Effect of early feeding of L-arginine and L-threonine on hatchability and post-hatch performance of broiler chicken.

This study aimed to evaluate the effect of in ovo feeding (IOF) of L-arginine (Arg) and L-threonine (Thr) in the broiler. For this purpose, 500 embryonated eggs were randomly allocated into five treatment groups of four replicates 25 eggs/replicate. The five treatments were arranged as (1) non-injected control, (2) 0.75% NaCl injected group, (3) 25 mg/egg Arg 4) 25 mg/egg Thr, and (5) Arg + Thr25 mg/egg. On the 17th day of incubation, 0.5 ml of treatment solution was injected into the amniotic fluid of all treatment groups. The result showed that the supplementation group of Arg + Thr significantly (P < 0.05) improved the hatchability, post-hatch growth performance, organ weight, and organ development in compression to sham control and other treatment groups. The antibiotic titer of NDV was improved in Arg + Thr group. Moreover, hematological indices were improved significantly in Arg + Thr group. The plasma concentration of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were noted to decrease in Arg + Thr group. Histopathological investigation revealed that IOF of Arg + Thr increased the villi length and crypt depth of the intestine. Conclusively, the IOF Arg and Thr could be an effective way to optimize the health and productive performance of broilers.

Effects of in ovo supplementation of selenium (Se) and zinc (zn) on hatchability and production performance of broiler chickens.

The current research was conducted to assess the effect of in ovo feeding (IOF) of selenium (Se) and zinc (Zn) on hatchability, production performance, liver, intestinal morphology, antioxidant levels and expression levels of immune-related genes in broiler chickens. A total of 400 fertilized eggs were equally divided into four groups: control (non-injected), sham (in ovo injection of 0.75% NaCl), Se (@ 1.5 µg/egg in ovo injection) and Zn (500 µg/egg in ovo injection) groups respectively. On the seventeenth day of incubation, treatment solutions were administered into amniotic fluid of fertilized eggs. The results revealed that Se and Zn supplementation significantly (P < 0.05) enhanced hatchability, post-hatch growth, organ development, and liver antioxidant capability. Histopathological examination revealed a typical hepatocyte morphology, well-arranged cells, and a significant (P < 0.05) decrease in apoptosis in both selenium and zinc groups. Additionally, selenium and zinc produced auspicious effects on intestinal epithelium and villi surface area. Interestingly, our results revealed that IOF of Se and Zn modulated the expression of immune-related genes in comparison to the control and sham groups. Conclusively, IOF of Se and Zn augmented health and productivity by enhancing the cellular immunity in the broiler chickens, thus IOF can be utilized as an effective strategy to promote health and immunity in broiler chickens.

Effects of Lactobacillus plantarum on Broiler Health: Integrated Microbial and Metabolomics Analysis.

Given China's prohibition on the utilization of antibiotics as feed additives in 2020, we aim to investigate nutrition additives that are both efficient and safe. Lactobacillus, a well-recognized beneficial probiotic, has explicitly been investigated for its effects on health status of the host and overall impact on food industry. To evaluate effects of Lactobacillus plantarum (LW) supplementation on broiler chicken, we conducted comprehensive multi-omics analysis, growth performance evaluation, RT-qPCR analysis, and immunofluorescence. The findings revealed that LW supplementation resulted in a substantial progress in growth performance (approximately 205 g increase in final body weight in comparison to the control group (p < 0.01)). Additionally, LW exhibited promising potential for enhancing antioxidant properties of serum and promoting gut integrity and growth as evidenced by improved antioxidant indices (p < 0.01), intestinal villus morphology (p < 0.01), and enhanced gut barrier function (p < 0.01). Meanwhile, the multi-omics analysis, including 16S rRNA sequencing and liquid chromatography-tandem mass spectrometry, revealed an enrichment of beneficial microbes in the gut of broilers that were supplemented with LW, while simultaneously depleting harmful microorganisms. Moreover, a noteworthy modification was observed in gut metabolic profiling subsequent to the execution of the probiotic strategy. Specifically, variations were noticed in the levels of metabolites and metabolic pathways such as parathyroid hormone synthesis, inflammatory mediator regulation of TRP channels, oxidative phosphorylation, and mineral absorption. Taken together, our findings validate that LW administration produces valuable effects on the health and growth performance of broilers owing to its capability to boost the gut microbiota homeostasis and intestinal metabolism. Present findings signify the potential of LW as a dietary additive to promote growth and development in broiler chickens.

Ameliorative effects of supranutritional selenium on TLR-4-NF-kB-TNF-α-mediated hepatic oxidative injury and inflammation in goats fed high concentrate diet.

We examined whether surplus dietary selenium (Se) supply could alleviate high concentrate (HC) diet-induced hepatic oxidative stress (OS) and inflammation. Eighteen young goats were distributed into three groups; were fed low (LC, concentrate: forage; 35: 65), high concentrate (HC, 65: 35), or Se-supplemented HC (HCSe, 65: 35 + 0.5 mg Se kg-1 diet) diets for 10 weeks. Short chain fatty acids, OS markers and immunoinflammatory genes expressions were assessed through gas chromatograph, kits, and RT-qPCR, respectively. Compared with LC, HC diet increased (p < .05) colonic and serum lipopolysaccharide (LPS) levels and induced hepatic oxidative injury by increasing (p < .05) malondialdehyde (MDA) levels and decreasing (p < .05) activities of glutathione peroxidase, superoxide dismutase, and catalase. HC diet altered hepatic mRNA expressions of toll-like receptor-4 (TLR-4), cluster of differentiation-14 (CD-14), tumor necrosis factor-α (TNF-α), TNF receptor-associated factor-6 (TRAF-6), nuclear factor kappa B (NF-κB), interleukin-1ß (IL-1ß), IL-10, IL-13, LPS-binding protein (LBP), serum amyloid A (SAA), α-acid glycoprotein (AGP), and albumin (ALB). Conversely, extra-Se supply lowered LPS and attenuated antioxidant status and inflammation in liver. In conclusion, HC diet induced oxidative lesions and TLR-4 pathway-mediated inflammation, whereas supranutritional Se alleviated oxidative and inflammatory lesions through TLR-4 pathway regulation in goat liver.

Screening of Proliferation-Related Genes and Pathological Changes in Thiram-Induced Tibial Dyschondroplasia.

Materials and Methods: Three hundred sixty (n = 360) broiler chickens were equally divided into control (C) and thiram (T) groups. Furthermore, the C and T groups were dividedinto 8-, 9-, 11-, and 13-day-old chickens. Results: Clinically, it was observed that broiler chickens of group T had abnormal posture, gait, and lameness, and histopathological results revealed dead and abnormal chondrocytes of T group on day 6. Real-time qPCR results showed that HDAC1, MTA1, H4, and PCNA genes were significantly expressed (P < 0.05). HDAC1 was upregulated on days 1, 2, 4, and 6 (P < 0.01); MTA1 was upregulated on days 1 and 2 (P < 0.01); H4 was upregulated on days 2 and 4 (P < 0.01), and PCNA was downregulated on days 1, 2, and 4 (P < 0.01). Furthermore, IHC results of HDAC1 protein were significantly (P < 0.01) expressed in proliferative zone of day 1 and hypertrophic zone of day 6. MTA1 protein was significantly (P < 0.01) expressed on days 1, 2, and 6 in all zones, except prehypertrophic zone of day 2. Conclusion: In conclusion, the mRNA expressions of HDAC1, MTA1, H4, and PCNA were differentially expressed in the chondrocytes of thiram-induced TD chickens. HDAC1 and MTA1 protein expression found involved and responsible in the abnormal chondrocytes' proliferation of broiler chicken.

Impact of therapeutic and high doses of florfenicol on kidney and liver functional indicators in goat.

AIM: The aim of this study was to evaluate the impact of therapeutic and high doses of florfenicol on kidney and liver functional indicators in goat species. MATERIALS AND METHODS: Six mature, healthy goats (combine breed and sex) with average weight 25 kg were selected for this study. The therapeutic (20 mg/kg b.w.) and high doses (40 and 60 mg) of florfenicol were administered for 3 days with 24 h interval. Blood samples were collected at 0, 24, 48, 72, 96, and 120 h following the each administered dose. RESULTS: The results showed that the therapeutic dose of florfenicol produced nonsignificant effect on serum urea, creatinine, total protein (TP), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and bilirubin on all timings, and increased (p<0.05) the serum glutamic oxaloacetic transaminase (SGOT) and serum glutamate-pyruvate transaminase (SGPT) levels for 48 h. Whereas the high doses of florfenicol (40 and 60 mg) significantly altered the kidney and liver functional indicators in the blood. In contrast with control, the serum urea level was (p<0.01) increased at all timing points. Creatinine values were altered (p<0.01, <0.05) in increasing manner from 24 to 96 h. The high dose of 40 mg decreased the TP (p<0.05) for 72 h and 60 mg persisted same effect (p<0.01) up to 120 h. The indices of ALP, GGT, SGOT, and SGPT were raised (p<0.01, <0.05) at all timings. The bilirubin indexes also (p<0.05) elevated from 48 to 72. CONCLUSION: It was concluded that the high doses of florfenicol produced reversible dose-dependent effects on functional indicators of kidney and liver such as urea, creatinine, TP, ALP, SGOT, SGPT, GGT, and bilirubin.
