Carcass Characteristics, Meat Quality and Nutritional Composition of Kadaknath, a Native Chicken Breed of India.

The study was carried out to investigate the carcass and meat quality traits and nutritional profile of the meat of the Kadaknath, a unique native chicken breed in comparison with commercial broilers. The yield of the carcass, breast and giblets of the Kadaknath was lesser (p < 0.01), while that of the legs, wings, back, and neck was higher (p < 0.01) than broilers. The meat of the Kadaknath was significantly (p < 0.0001) darker (42.44, 50.92) and more yellow (6.23, 8.99) than broilers. The decline in pH of the meat was lower (p < 0.001) in the Kadaknath compared to broilers. Kadaknath meat had more protein and less fat, moisture and ash content than broilers (p < 0.01). Furthermore, it was richer (p < 0.01) in 11 amino acids, including those which are known to impart a sweet and umami taste, than the meat of broilers (3 amino acids). Both genotypes were almost similar in meeting the daily requirements of indispensable amino acids of adult human. The study concluded that the Kadaknath differed in carcass and meat quality characteristics from the broilers, and the nutritional quality of Kadaknath meat in terms of high protein and less fat and higher content of amino acids (tasty type) was better in Kadaknath meat as compared to broiler meat.

Effect on physiological and production parameters upon supplementation of fermented yeast culture to Nicobari chickens during and post summer.

Nicobari is an indigenous bird reared for meat and eggs. This study evaluated the effect of heat stress on plasma levels of leptin, growth hormone and their receptors, liver AMP kinase, plasma cholesterol and lipid peroxide (MDA). The laying period coincided with the post summer period. The birds were equally divided into three groups, control group was offered ad libitum feed and treatment groups were supplemented with fermented yeast culture at 700 mg (T1) and 1.4 g/kg (T2) of feed/day. The levels of plasma Leptin and GH hormones were higher (p < 0.05) in the control group when compared to the treatment groups. The expression of the hormone receptors was higher in the brain, and MMP3 gene expression in the magnum was lower in the treatment group. Plasma cholesterol, MDA and AMP kinase were significantly higher (p < 0.05) in the control group. Fermented yeast culture supplementation decreased feed intake and increased egg production parameters, which indicates a greater efficiency of supplementation. Supplementation reduced the severity of necrosis of villi in the jejunum when compared to control. In conclusion, higher ambient temperature during summer had negative effect on production parameters through modulation of physiological parameters which could be ameliorated by supplementation of FYC.

Estimation of breeding value, genetic parameters and maternal effects of economic traits in rural male parent line chicken using pedigree relationships in an animal model.

Breeding value (BV), genetic parameters and additive genetic, and maternal effects were evaluated on growth and production traits utilizing data from eight generations employing animal model in a rural male parent line (PD-6) chicken at ICAR-Directorate of Poultry Research, Hyderabad, India. The least squares means (LSM) for body weight (BW) and shank length (SL) up to 6 weeks of age varied significantly (p ≤ .01) among the generations and hatches. BW increased significantly (p ≤ .01) over the generations and decreased with the hatches. Sex also had a significant effect on BW and shank length except for BW at 0 day (BW0). LSM for BW (BW6) and Shank length (SL6) at 6 weeks of age were 598.84 ± 0.79 g and 74.57 ± 0.04 mm, respectively. Males recorded significantly (p ≤ .01) higher BWs and shank length. All the production traits were significantly (p ≤ .01) influenced by the generation effect. The overall LSM for age at sexual maturity (ASM), egg production at 40 weeks (EP40) and egg weight at 40 weeks (EW40) were 164.93 ± 0.23 days, 74.66 ± 0.40 eggs and 54.79 ± 0.08 g, respectively. Model 3 with additive, maternal permanent environmental and residual effects was the appropriate model for BW2, BW4, BW6, SL4 and SL6, whereas Model 4 with maternal effects was the best for BW0. The heritability estimates for BW6 and SL6 were 0.22 ± 0.02 and 0.18 ± 0.02, respectively. Model 1 with additive direct and residual effects was the best appropriate model for all the production traits. The heritability estimates of EP40 and EW40 were 0.16 ± 0.04 and 0.34 ± 0.05, respectively. BW and shank length were highly correlated with significant (p ≤ .05) positive association from different components. The correlation coefficient from direct additive component between egg production and BW40 was negative, while it was positive with less magnitude between egg production and BW20. The egg production and egg weights had a negative association at different ages. BV of SL6, the primary trait of selection, was significant (p ≤ .05) across the generations and increased linearly with an average genetic gain of 1.05 mm per generation. BV of BW6 was also significant (p ≤ .05) and increased linearly as correlated response with an average genetic response of 22.34 g per generation. BV of EP40 showed an increasing trend with a genetic gain of 0.02 eggs per generation. The EW 40 also increased linearly with an average genetic gain of 0.06 g. The average inbreeding coefficient of the population was 0.015. The study concluded that the population was in ideal status with a linearly increasing trend of average BV with negligible inbreeding over the eight generations of selection.

A Case of Cheilitis Granulomatosa/Orofacial Granulomatosis.

A case of a 19-year-old female patient is presented to a private practice dental clinician with swelling of the lower lip and inflammation of the anterior dorsal tongue. The patient presented with moderate oral pain as well as abdominal pain. The lesions were biopsied and noted for a granulomatous histopathologic appearance. The patient reported a history of using cinnamon as a flavoring agent. The lesions resolved within two weeks after the biopsy procedures and topical steroid therapy. The lesions were diagnosed as cheilitis granulomatosa/orofacial granulomatosis. The patient has remained lesion free as of the three-year follow-up. Etiologic, diagnostic and therapeutic issues related to this relatively rare condition of cheilitis granulomatosa/orofacial granulomatosis are discussed.

Effect of FecB status on the allometric measurements and reproductive performance of Garole × Malpura ewes under hot semi-arid environment.

The study was conducted with the primary objective to establish the influence of FecB gene mutation on the growth and reproductive performance of Garole × Malpura ewes. The duration of the study was for 5 months involving 97 adult Garole × Malpura (GM) ewes. These 97 animals were segregated based on FecB genotype and the animals were divided into three groups as group I (FecB(BB) ; n = 13), group II (FecB(B+); n = 65), and group III (FecB(++); n = 19). All the animals were kept under semi-intensive management system by subjecting the animals to grazing during day time and housing them in the night. Apart from grazing, ewes were provided with concentrate mixture at the rate of 150 g/day/ewe. The ewes in estrus after 12 h of onset of estrus were hand mated twice at 12-h intervals with a ram of proven fertility in the morning and evening. The pregnancy was confirmed by real time B-mode transabdominal ultrasonography. The experiment was continued until lambing. Under the treatments of different FecB genotype, the ewe's growth and reproductive parameters were assessed. FecB genotype significantly (P < 0.05) influenced body weight, heart girth, pin shoulder length, height at wither, lambing percentage, litter size, twinning percentage, and birth weight of lambs. From this study, it can be concluded that breeding Galore and Malpura breed shall help insure an economically viable production system.

Using insurance claims and demographic data for surveillance of children's oral health.

OBJECTIVES: This paper examines the utility of using private insurance and Medicaid dental claims as well as demographic data for assessing the oral health of children aged 5-12 years in Genesee County, Michigan, communities. METHODS: Dental insurance claims data from Delta Plan of Michigan and Michigan Medicaid, plus demographic data from the 1990 US Census (percent poverty) and from the 1995 National Center for Educational Statistics (percent free or reduced lunch eligibility), were compared to findings from two school-based oral health surveys. These surveys were the 1995 Genesee County Oral Health Survey and the 1998-2001 Mott Children's Health Center oral health screenings. Data were analyzed using zip codes, representing communities, as the comparison unit. Statistical comparisons using correlation coefficients were used to compare the findings from the six data sets. RESULTS: Using the insurance claims and school-based data, some communities consistently demonstrated high levels of dental caries or treatment for the primary dentition. The demographic measures were significantly associated with many of the primary dentition survey measures. The demographic data were more useful in identifying communities with high levels of dental disease, particularly in the primary teeth, than the insurance claims data. CONCLUSIONS: When screening is not practical, readily available demographic data may provide valuable oral health surveillance information for identification of high-risk communities, but these data do not identify high-risk individuals. In these analyses, demographic data were more useful than dental insurance claims data for oral health surveillance purposes.

Early childhood caries and quality of life: child and parent perspectives.

PURPOSE: The purpose of this study was to investigate the effects of early childhood caries (ECC) on children's oral health-related quality of life (QOL) before and 4 weeks after its treatment, as assessed by the children themselves as well as by their parents/guardians. METHODS: This study had a longitudinal intervention design. Sixty-nine children diagnosed with ECC and 43 children without caries (combined children's mean age=50.4 months; range=22 to 70 months) and their parents/guardians responded to face-to-face administered surveys before a dental treatment was started (baseline assessment). Thirty-seven children with ECC completed dental rehabilitation. Four weeks after the treatment was completed, these 37 children as well as their parents/guardians responded to a second survey (follow-up assessment). RESULTS: The results show that children with ECC have significantly lower oral health-related QOL than children without ECC as assessed both by the children and the parents/guardians at baseline. The children with ECC who received dental treatment had a significantly improved oral health-related QOL at the follow-up assessment when compared with their baseline measurement as measured both with the children's self-ratings of oral health-related QOL and the parents'/guardians' perception of their child's oral health-related QOL. CONCLUSIONS: ECC and its treatment affect children's oral health-related QOL in a significant way. Oral health-related QOL can be assessed validly and reliably both in self-reports from children as young as 36 months of age as well as by asking parents/guardians about their perceptions of their child's oral health-related QOL.
