The impact of psychiatric comorbidities on emergency general surgical patients' outcomes.

BACKGROUND: Psychiatric disorders are increasingly prevalent. Studies have demonstrated that the presence of comorbid psychiatric conditions (CPC) is associated with a number of worsening outcomes in hospitalised patients in general. The relationship between a wide range of psychiatric comorbidities and acute surgical presentations has not been studied to date. STUDY DESIGN: The Hospital In-Patient Enquiry (HIPE) system and prospectively maintained eHandover were used to identify all surgical emergency admissions to Mayo University Hospital, Ireland. Patient demographics, comorbidities, primary diagnoses, length of stay (LoS), and procedures undergone were recorded over a 12-months period. Subgroup analyses examining LoS variation in surgical presentation types were performed. RESULTS: 1028 admissions occurred over this one year period, amongst 995 patients, the presence of psychiatric comorbidities increased the mean LoS by 1.9 days (p = 0.002). Comorbid depression, dementia, and intellectual disability conferred a significant increase in LoS by 2.4 days, 2.8 days and 6.7 days respectively. Subgroup analysis revealed greater LoS in patients with CPC diagnosed with non-specific abdominal pain (1.4 days, p = 0.019), skin and soft tissue infections (2.5 days, p = 0.040), bowel obstruction (4.3 days, p = 0.047), and medical disorders (18.6 days, p = 0.010). No significant difference was observed in mortality and readmission rates. CONCLUSION: Psychiatric comorbidities significantly impact length of hospital stay and discharge planning in surgical inpatients. Greater awareness of this can facilitate better care delivery for this population to reduce the LoS and subsequent economic burden on the healthcare system.

[Cotton Leaf Curl Multan Betasatellite as a Tool to Study the Localization of Geminiviruses in Plants].

Cotton leaf curl Multan betasatellite (CLCuMB) is a ubiquitous betasatellite commonly found along with cotton leaf curl disease (CLCuD) associated begomoviruses in the Old World. It has a promiscuous replicative nature and trans-replicated by a diverse range of geminiviruses. CLCuMB encodes a single ORF, ßCl, in the complementary direction and has pathogenicity, symptoms determinant, suppressor of post-transcription and transcription gene silencing functions. After substituting the ßC1 gene with the target gene, it has been used successfully as a gene delivery vector. In the present study, the ßC1 gene of CLCuMB was substituted with the green fluorescent protein (GFP) gene, and the resulting construct utilized as a reporter vector to decipher in planta localization of geminiviruses. The recombinant CLCuMB expressing GFP (CLCuMB-GFP) was co-inoculated to Nicotiana benthamiana plants either with Cotton leaf curl Kokharan virus (CLCuKoV) alone or in a combination with the wild type CLCuMB to investigate the objectives of the study. Results showed that CLCuKoV successfully supported the replication and systemic movement of CLCuMB-GFP either alone or in the presence of wild type CLCuMB. The presence of CLCuMB-GFP was readily detected with PCR and Southern blot hybridization. The modified CLCuMB may serve as a tool useful for in planta localization of geminiviruses.

Comparison of chemical extraction methods for determination of 146S content in foot-and-mouth disease oil-adjuvanted vaccine.

AIMS: To compare antigen extraction efficiency of chemical methods such as benzyl alcohol, chloroform, sodium citrate, extraction buffer with Tween-20 (EBT) and isopropyl myristate for determination of 146S content in the fresh and stored FMD oil-adjuvanted vaccines. METHODS AND RESULTS: Standard vaccine with antigen payload of 10, 5 and 5 µg per cattle dose (2 ml) for serotypes O, A and Asia1, respectively, was used to compare the antigen extraction efficiency of five chemical methods: benzyl alcohol, chloroform, sodium citrate, EBT buffer and isopropyl myristate. The purity of the extracted 146S antigen was quantified by caesium chloride (CsCl) ultracentrifugation. Serotype-specific sandwich ELISA (sELISA) was developed to identify the serotype and to compare the 146S in aqueous phase and ultrafractions. The antigen recovery was also tested in stored trivalent vaccine. Coefficient of regression was calculated to assess the predictive power of the benzyl alcohol extraction method. Of the five methods, benzyl alcohol showed consistent antigen recovery of >90% in monovalent as well as trivalent vaccines. Ultrafraction showed a 1·4 ratio at A259/239 nm in UV spectrophotometry indicating the presence of 146S. sELISA revealed that the antigen recovery was significantly less in ultrafractions than that of aqueous phase. Further, there was no significant difference in antigen recovery from stored trivalent vaccine for 12 months, indicating the usefulness of the benzyl alcohol method. Linear regression model revealed R2  = 0·99 with a narrow band of predictive interval. CONCLUSIONS: The benzyl alcohol method was efficient in extracting 146S from the monovalent and trivalent fresh and stored FMD vaccines. CsCl density gradient precisely quantified the 146S, while sELISA identified the serotype of the vaccine. SIGNIFICANCE AND IMPACT OF THE STUDY: When the benzyl alcohol method is coupled with CsCl density gradient and sELISA, it has the potential to determine the 146S content of FMD vaccine.

Flock use of the range is associated with the use of different components of a multi-tier aviary system in commercial free-range laying hens.

1. The objective of this study was to investigate the association of using a multi-tier aviary system and access to range on flock uniformity in free-range laying hens, and to determine whether the extent of range use or flock uniformity can be predicted from the use of different levels of the aviary system.2. A total of 13,716 Lohmann Brown hens from five commercial free-range flocks housed in identical houses on the same farm were individually weighed at 16 weeks of age and allocated to five replicate areas within each house. Hen movement in the multi-tier aviary system and on the range was individually monitored using radio frequency identification (RFID). All hens had access to the range from 18 to 22 weeks of age and were exposed to the same management conditions.3. Whilst only one flock significantly changed its flock uniformity with time, they differed from each other in uniformity and body weight (P = 0.001).4. Hens spent most of their available time on the lower aviary tier (7.29 ± 0.029 h/hen/day) and on the upper aviary tier (4.29 ± 0.024 h/hen/day) while the least amount of time was spent on the range and in the nest boxes (0.93 ± 0.005 h/hen/day and 1.48 ± 0.007 h, respectively, P = 0.001).5. Range use was negatively correlated (r = -0.30) to the time spent on the upper aviary tier and positively correlated (r = 0.46) to the time spent on the lower aviary tier (P = 0.001). Bivariate analysis revealed that range and upper aviary resp. lower aviary tier usage had a significant curvilinear association.6. In conclusion, the study showed that range use was associated to the time hens spent on the different tiers of the aviary system. Flock uniformity varied between flocks but was not associated with either range and aviary system usage.

The antisense 5' end of the V2 gene confers enhanced resistance against the monopartite begomovirus cotton leaf curl Kokhran virus-Burewala strain.

Whitefly-transmitted viruses of the genus Begomovirus (the family Geminiviridae) have become a limiting factor for agricultural productivity in many warmer parts of the world. The economies of Pakistan and India have, since the early 1990s, suffered losses due to cotton leaf curl disease (CLCuD). The disease is caused by begomoviruses, the most important of which at this time is cotton leaf curl Kokhran virus strain Burewala (CLCuKoV-Bu), and a disease-specific betasatellite, cotton leaf curl Multan betasatellite (CLCuMuB). Efforts to minimize losses due to CLCuD rely mainly on the use of insecticides to kill the whitefly vector; no resistant cotton varieties are currently commercially available. The study described here has investigated RNA interference technology for its potential to yield resistance against CLCuKoV-Bu and three other begomoviruses; CLCuKoV, tomato leaf curl New Delhi virus (ToLCNDV) and Pedilanthus leaf curl virus (PeLCV). Three fragments of the virion-sense V2 gene of CLCuKoV-Bu were transformed into Nicotiana benthamiana in antisense orientation and transgenic lines expressing virus-specific short RNAs were assessed for their ability to yield resistance. Only CLCuKoV-Bu with the V2 sequence closest to the promoter was resistant. Inoculation of CLCuKoV-Bu with CLCuMuB into transgenic plants did not significantly affect the outcome, although viral DNA was detected in number of plants, suggesting that the betasatellite may impair RNAi resistance. Overall the results indicate that targeting the 5' end of V2 gene using antisense-RNA has the potential to deliver resistance against begomoviruses and that RNAi-based resistance imparts some degree of resistance to heterologous viruses. Keywords: geminivirus; begomovirus; RNAi; resistance; CLCuKoV-Burewala; CLCuMuB.

Exome sequencing of Pakistani consanguineous families identifies 30 novel candidate genes for recessive intellectual disability.

Intellectual disability (ID) is a clinically and genetically heterogeneous disorder, affecting 1-3% of the general population. Although research into the genetic causes of ID has recently gained momentum, identification of pathogenic mutations that cause autosomal recessive ID (ARID) has lagged behind, predominantly due to non-availability of sizeable families. Here we present the results of exome sequencing in 121 large consanguineous Pakistani ID families. In 60 families, we identified homozygous or compound heterozygous DNA variants in a single gene, 30 affecting reported ID genes and 30 affecting novel candidate ID genes. Potential pathogenicity of these alleles was supported by co-segregation with the phenotype, low frequency in control populations and the application of stringent bioinformatics analyses. In another eight families segregation of multiple pathogenic variants was observed, affecting 19 genes that were either known or are novel candidates for ID. Transcriptome profiles of normal human brain tissues showed that the novel candidate ID genes formed a network significantly enriched for transcriptional co-expression (P<0.0001) in the frontal cortex during fetal development and in the temporal-parietal and sub-cortex during infancy through adulthood. In addition, proteins encoded by 12 novel ID genes directly interact with previously reported ID proteins in six known pathways essential for cognitive function (P<0.0001). These results suggest that disruptions of temporal parietal and sub-cortical neurogenesis during infancy are critical to the pathophysiology of ID. These findings further expand the existing repertoire of genes involved in ARID, and provide new insights into the molecular mechanisms and the transcriptome map of ID.

Consumer segmentation and time interval between types of hospital admission: a clinical linkage database study.

Background: Healthcare policies target unplanned hospital admissions and 30-day re-admission as key measures of efficiency, but do not focus on factors that influence trajectories of different types of admissions in the same patient over time. Objectives: To investigate the influence of consumer segmentation and patient factors on the time intervals between different types of hospital admission. Research design, subjects and measures: A cohort design was applied to an anonymised linkage database for adults aged 40 years and over (N = 58 857). Measures included Mosaic segmentation, multimorbidity defined on six chronic condition registers and hospital admissions over a 27-month time period. Results: The shortest mean time intervals between two consecutive planned admissions were: 90 years and over (160 days (95% confidence interval (CI): 146-175)), Mosaic groups 'Twilight subsistence' (171 days (164-179)) or 'Welfare borderline' and 'Municipal dependency' (177 days (172-182)) compared to the reference Mosaic groups (186 days (180-193)), and multimorbidity count of four or more (137 days (130-145)). Mosaic group 'Twilight subsistence' (rate ratio (RR) 1.22 (95% CI: 1.08-1.36)) or 'Welfare borderline' and 'Municipal dependency' RR 1.20 (1.10-1.31) were significantly associated with higher rate to an unplanned admission following a planned event. However, associations between patient factors and unplanned admissions were diminished by adjustment for planned admissions. Conclusion: Specific consumer segmentation and patient factors were associated with shorter time intervals between different types of admissions. The findings support innovation in public health approaches to prevent by a focus on long-term trajectories of hospital admissions, which include planned activity.

Pasture, multi-enzymes, benzoic acid and essential oils positively influence performance, intestinal organ weight and egg quality in free-range laying hens.

1. The objective of this study was to investigate the effect of range type, multi-enzyme applications, and a combination of benzoic acid (BA) and essential oils (EO) on the productive performance, organ weight and egg quality of free-range laying hens. 2. Three hundred laying hens were evaluated for the short-term (6 weeks) and long-term (12 weeks) effects of range type (G = no pasture, P = pasture) and feed additives (T1 = control; T2 = betaglucanase/pectinase/protease; T3 = BA/EO). Body weight, feed intake (FI), feed conversion ratio (FCR), egg production (EP), digestive organ weight, and egg quality (EQ) were evaluated. Data were analysed using SPSS 2.2 in a 2×2×3 factorial arrangement. 3. Hens that ranged on pasture were significantly heavier (2043 g vs. 1996 g; p < 0.001), laid heavier eggs (61.9 g vs. 60.3 g; p < 0.001) and produced darker yolk colour (4.3 vs. 7.0; p < 0.001) compared to hens ranged on gravel. Hens fed T2 were significantly heavier (2050 g) compared to hens fed T1 (2005 g) or T3 (2008 g). Organ weights (gizzard, liver and pancreas) were significantly heavier in hens ranged on pasture (16.8 g/kg BW, 22.3 g/kg BW and 1.89 g/kg BW, respectively) compared to hens ranged on gravel (14.2 g/kg BW, 21.7 g/kg BW and 1.83 g/kg BW, respectively). Over time, body weight (1970-2070 g; p < 0.001) and egg weight (59.5-62.8 g; p < 0.001) increased, FI (123-120 g; p = 0.024) was reduced and FCR (2.36-2.10; p = 0.002) improved 4. In conclusion, hens housed on pasture and fed multi-enzyme supplemented diets had significantly heavier body weight and produced heavier eggs with darker yolk colour. Pasture intake and enzyme supplementation increased digestive organ weight significantly.

Effect of different head-neck-jaw postures on cervicocephalic kinesthetic sense.

OBJECTIVES: To investigate the effect of different induced head-neck-jaw postures on head-neck relocation error among healthy subjects. METHODS: 30 healthy adult male subjects participated in this study. Cervicocephalic kinesthetic sense was measured while standing, habitual sitting, habitual sitting with clenched jaw and habitual sitting with forward head posture during right rotation, left rotation, flexion and extension using kinesthetic sensibility test. RESULTS: Head-neck relocation error was least while standing, followed by habitual sitting, habitual sitting with forward head posture and habitual sitting with jaw clenched. However, there was no significant difference in error between different tested postures during all the movements. CONCLUSIONS: To the best of our knowledge, this is the first study to see the effect of different induced head-neck-jaw postures on head-neck position sense among healthy subjects. Assuming a posture for a short duration of time doesn't affect head-neck relocation error in normal healthy subjects.

The Utility of Neutrophil to Lymphocyte Ratio as a Predictor of Intervention in Acute Diverticulitis.

BACKGROUND: Neutrophil to lymphocyte ratio (NLR) is a novel biomarker that has been recently studied in diverticulitis. The primary aim of this study was to assess the accuracy of NLR in predicting which patients had complicated diverticulitis and which patients required a radiological or surgical intervention. The accuracy of NLR was compared to C-reactive protein (CRP), white blood cell (WBC) count, neutrophil count and white cell to lymphocyte ratio (WLR). METHODS: Details of all patients admitted with acute diverticulitis over an 18-month period were collected prospectively. Median CRP, WBC, neutrophil count, WLR and NLR values at initial presentation were compared using the Mann-Whitney U test. The diagnostic accuracy of each test was assessed using receiver operating characteristic curve analysis. Optimal cut-off points were determined for each biomarker using Youden's Index (J). RESULTS: CRP, WBC, neutrophil count, WLR and NLR had variable accuracy in predicting complicated diverticulitis. NLR had the greatest accuracy of the 5 biomarkers in predicting the need for intervention with an area under the curve of 0.79 (p < 0.0001). The optimal cut-off point for NLR was 5.34 (J = 0.45). CONCLUSION: NLR was more accurate than CRP, WBC, neutrophil count and WLR in predicting the need for intervention. This cost-neutral, readily available biomarker can easily be calculated from the complete blood count and is a useful adjunct to CT.

Comprehensive genome-wide evaluation of lapatinib-induced liver injury yields a single genetic signal centered on known risk allele HLA-DRB1*07:01.

Lapatinib is associated with a low incidence of serious liver injury. Previous investigations have identified and confirmed the Class II allele HLA-DRB1*07:01 to be strongly associated with lapatinib-induced liver injury; however, the moderate positive predictive value limits its clinical utility. To assess whether additional genetic variants located within the major histocompatibility complex locus or elsewhere in the genome may influence lapatinib-induced liver injury risk, and potentially lead to a genetic association with improved predictive qualities, we have taken two approaches: a genome-wide association study and a whole-genome sequencing study. This evaluation did not reveal additional associations other than the previously identified association for HLA-DRB1*07:01. The present study represents the most comprehensive genetic evaluation of drug-induced liver injury (DILI) or hypersensitivity, and suggests that investigation of possible human leukocyte antigen associations with DILI and other hypersensitivities represents an important first step in understanding the mechanism of these events.

Production and characterization of novel self-assembling biosurfactants from Aspergillus flavus.

AIM: This work was conducted to produce, purify and characterize biosurfactants from Aspergillus flavus AF612 isolated from citrus fruit. METHODS AND RESULTS: Biosurfactant named 'Uzmaq' was isolated from A. flavus AF612. The chemical characterization of the biosurfactant was conducted. Biosurfactant Uzmaq produced by A. flavus, was composed of methoxy phenyl oxime glycosides. Two molecular forms of the biosurfactant, Uzmaq-A and Uzmaq-B were isolated. Biological properties (antifungal activity) were evaluated. The fractions of the biosurfactant were isolated and their surface properties were analysed. Uzmaq-A and Uzmaq-B had critical micelle concentration (CMC) around 170 and 80 mg l(-1) , and lowered surface tension of water up to 20 and 25 m Nm(-1) respectively. The biosurfactants were stable at pH 3-12 and temperature up to 80°C. Growth and biosurfactant production kinetics were also analysed. CONCLUSION: Novel biosurfactant Uzmaq was produced from A. flavus, which was composed of methoxy phenyl oxime glycosides. The surface activity of Uzmaq was better than the maximum values of synthetic chemical surfactants. The biosurfactant showed antifungal activity and self-assembling properties. SIGNIFICANCE AND IMPACT OF THE STUDY: Aspergillus flavus AF612 can be used for commercial production of Uzmaq that may be employed for controlled drug release applications and bioremediation.

Vitamin D deficiency and dyslipidemia in early pregnancy.

BACKGROUND: Vitamin D deficiency is a common nutritional issue and dietary supplementation in the general population, including pregnant women, is generally advised. Appropriately high levels of vitamin D are expected to play a role in containing the glycemic and atherogenic profiles observed in pregnancy. However, the relation between vitamin D status and the lipid metabolic profile in Saudi women, who are known to suffer from chronic vitamin D deficiency and high incidence of obesity and type II DM, during the course of pregnancy is not known. METHODS: In this study, we analyzed the relation between serum vitamin D level and various serum metabolic markers among Saudi women (n = 515) in their first trimester of pregnancy (11.2 ± 3.4 weeks). Coefficients of Pearson correlation and Spearman rank correlation were calculated for Gaussian and non-Gaussian variables, respectively. Serum vitamin D status was defined as (in nmol/L): deficient (<25), insufficient (25-50); sufficient (50-75) and desirable (>75). RESULTS: Results indicated that vitamin D status was sufficient in only 3.5% of the study participants and insufficient and deficient in 26.2% and 68.0% of participants, respectively. Serum vitamin D values in the overall study population correlated positively with serum levels of total cholesterol (R = 0.172; p < 0.01), triglycerides (R = 0.184; p < 0.01) and corrected calcium (R = 0.141; p < 0.05). In the subgroup of vitamin D deficient subjects (n = 350), log serum vitamin D values correlated with serum triglycerides (R = 0.23; p = 0.002) and cholesterol (R = 0.26; p = 0.001). CONCLUSIONS: The positive correlations between serum vitamin D and the atherogenic factors such as total cholesterol and triglycerides indicate a pro-atherogenic metabolic status in vitamin D deficient expectant mothers. This may represent an adaptation to the high metabolic demands of pregnancy.

A National Evaluation of the Conservative Management of Uncomplicated Acute Appendicitis: How Common Is This and What Are the Issues.

INTRODUCTION: The management approach for acute appendicitis has been challenged in recent years, with numerous randomized controlled trials demonstrating that antibiotics/conservative management is an efficacious treatment, with lower complication rates. METHODS: A national survey of all consultant general surgeons evaluating their practices was performed. Reasons for changed practices, choice of antibiotics and follow-up investigations were evaluated. In addition, the role of interval appendicectomy and conservative management in the pediatric population was also assessed. RESULTS: The response rate for this survey was 74.7% (n = 74/99). Over one-fifth (n = 17, 22.9%) routinely treat acute appendicitis conservatively, while another 14.8% (n = 11) consider this approach in selected cases. Main reasons for modified practices included the presence of inflammatory phlegmon (75%), delayed presentation (64%), and recent evidence-based medicine developments (46%). Co-amoxiclav/clavulanic acid was the most popular antibiotic for conservative management (53%). Alternatively, combinations of antibiotics were also utilized. One-third felt interval appendicectomy was warranted, while one-fifth supported conservative management in the paediatric setting. The overwhelming majority (>95%) advocate follow-up colonoscopy ± computed tomography in any patient aged >40 years managed conservatively. CONCLUSION: Considerable variation in management of uncomplicated appendicitis remains in Ireland despite growing evidence suggesting that the non-operative approach is safe. Reasons for adopting a conservative management practice have been identified and reflect the expanding literature on this subject.

The Utility of Neutrophil-to-Lymphocyte Ratio as a Severity Predictor of Acute Appendicitis, Length of Hospital Stay and Postoperative Complication Rates.

BACKGROUND: Numerous screening tools have been reported to aid in diagnosing appendicitis, but have poor severity prediction and lack accurate estimation of postoperative complications or total length of hospital stay (LOS). AIM: This study aims at evaluating the utility of neutrophil-to-lymphocyte (NLR) ratio in predicting the severity of appendicitis, LOS and 30-day complication rates. METHODS: Patients who underwent appendicectomy over a 4-year period were evaluated. Demographics, blood results, severity of appendicitis, LOS and 30-day complications were recorded. Recommended cut-off values of NLR and C-reactive protein (CRP) for severity of appendicitis were determined using receiver operating characteristic analysis. The Mann-Whitney test was performed to assess the correlations between LOS and 30-day complications with NLR. RESULTS: A total of 663 patients were included in the study of which 57.3% (n = 380) were male with mean patient age of 23.6 years, and 461 appendix specimens (69.6%) had simple inflammation on histological evaluation. A NLR of >6.35 or CRP of >55.6 were statistically associated with severe acute appendicitis, with a median of one extra hospital day admission (p < 0.0001). Mean NLR was statistically higher in patients with postoperative co(13.69 for severe vs. 7.29 for simple appendicitis group, p = 0.016). CONCLUSION: We advocate that NLR is a useful adjunct in predicting severity of appendicitis. It aids in delineating severe inflammation requiring surgery without substantial delay.

Solid lipid nanoparticles of anticancer drug andrographolide: formulation, in vitro and in vivo studies.

Diterpenoidal anti-cancer drug andrographolide (AD) was encapsulated into solid lipid nanoparticle (SLN) because of poor aqueous solubility and high lipophilicity. AD-SLNs were prepared by solvent injection method and characterized for droplet size, surface morphology, zeta potential, etc. In vitro drug release was carried out by dialysis-membrane method. A pharmacokinetic study was performed by UPLC/Q-TOF-MS method to determine the maximum plasma concentration (Cmax), area under the curve (AUC), etc. There was an improvement in Cmax and AUC of AD-SLNs when compared with AD, thereby enhancing the bioavailability of AD. The tmax was increased than that of AD suspension, indicating the sustained release pattern of AD-SLNs. The antitumor activity was carried out on Balb/c mice showing better results with AD-SLNs as compared to AD. Thus, the AD-loaded SLNs would be useful for delivering poorly water-soluble AD with enhanced bioavailability and improved antitumor activity.

Effects of selenium supplementation on the growth performance, slaughter characteristics, and blood biochemistry of naked neck chicken.

This study examined how selenium-supplemented diets affected the performance of naked neck chickens. The birds were fed both organic and inorganic selenium at 0.30 ppm, while the control diet did not include any additional selenium. A total of 225 one-day-old naked neck chicks were randomly divided into 3 experimental groups, each of which was replicated 5 times (replicates) and contained 15 birds. This was done using a completely randomized design. The data was collected after growth, meat quality, and blood profile parameters were assessed. The findings showed that the birds fed inorganic selenium in the diet displayed increased (P < 0.05) feed intake followed by those administered organic selenium and the control diet. On the other hand, birds fed organic selenium in the diet showed enhanced body weight gain and better feed conversion ratio (P < 0.05). Similarly, organic selenium supplementation increased (P < 0.05) breast and thigh weight compared to inorganic selenium, but no other metrics, such as dressing percentage, drumstick weight, liver weight, gizzard weight, heart weight, or wing weight, significantly differed between treatments (P > 0.05). When compared to birds fed inorganic Se and control diet, the birds fed organic Se had greater (P < 0.05) blood levels of total protein and globulin. Additionally, it was discovered that organic Se-fed birds had greater (P < 0.05) blood Se concentrations than control and inorganic Se-fed birds. However, no differences between treatments were found in albumin, glucose, cholesterol, triglycerides, or uric acid (P > 0.05). In conclusion, adding Se-enriched yeast, as an organic selenium source, to diets may enhance the poor growth and slaughter characteristics of naked neck chicks without negatively affecting blood chemistry.

Organoleptic characteristics and compositional profile of meat of growing Japanese quail fed different levels of poultry byproducts compost.

The poultry industry generates a lot of waste, including dead birds, manure, and poultry litter. Poultry waste should never be disposed of improperly because it can seriously harm the environment. The waste can be recycled as a feedstock for use in poultry feed by composting the litter and deceased birds. The compositional profile and organoleptic properties of the meat of growing Japanese quail were examined over the course of a 4-week trial to ascertain the effect of adding compost to the diet. In a completely randomized design (CRD), 1200 newly hatched quail chicks (Coturnix coturnix japonica) were divided into five treatment groups (diets with 0, 2.5, 5, 7.5, and 10% compost), each consisting of 40 birds with six replicates. The addition of compost to the diet had no noticeable effects on the organoleptic qualities of appearance, color, aroma, taste, texture, juiciness, tenderness, and acceptability (P>0.05). The compositional profile characteristics for chicks given compost at any level compared to chicks fed the control diet showed no differences (P>0.05). These findings suggest that the sensory characteristics and compositional profile of growing meat quails can be maintained when fed diets including up to 10% compost.
