The chicken major histocompatibility complex (MHC) has abundant SNP and indels, and is closely related with host genetic resistance or susceptibility to disease. The LEI0258 locus is the most variable in the MHC region, and is a useful marker in reflecting the variability of MHC. In this study, we applied the LEI0258 microsatellite marker to investigate polymorphism of MHC in Chinese indigenous...

Data from population-based studies and national surveillance systems were collated and analyzed to estimate the impact of disease and risks associated with eating different foods in England and Wales. From 1996 to 2000, an estimated 1,724,315 cases of indigenous foodborne disease per year resulted in 21,997 hospitalizations and 687 deaths. The greatest impact on the healthcare sector arose from...

Chicken is the most common poultry species and is important to human societies. Tibetan chicken (Gallus gallus domesticus) is a breed endemic to China that is distributed mainly on the Qinghai-Tibet Plateau. However, its origin has not been well characterized. In the present study, we sequenced partial mitochondrial DNA (mtDNA) control region of 239 and 283 samples from Tibetan and Sichuan indi...

Indigenous (native) breeds of livestock have higher disease resistance and adaptation to the environment due to high genetic diversity. Even though their extinction rate is accelerated due to the increase of commercial breeds, natural disaster, and civil war, there is a lack of well-established databases for the native breeds. Thus, we constructed the native pig and chicken breed database (NPCD...

The data on ten SNP markers of Myostatin gene (GDF-8) was generated on nine breeds/populations of indigenous poultry and Red Jungle Fowl (RJF). The SNPs were five in promoter region, one each in intron 1 and 2 and three in exon 1. The data was analyzed to find out the genetic relationship among the indigenous chicken populations. PCR-RFLP was carried out to genotype the populations at seven SNP...

AIM Chicken astroviruses (CAstV) are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada. MATERIALS AND METHODS Blood samples from 366 indigenou...

This study aimed to screen single nucleotide polymorphisms (SNPs) in the chicken gap junction protein alpha 1 (GJA1) gene, and to investigate their association with five growth traits measured in 269 chickens encompassing Chinese indigenous Beijing-You (BJY) and commercial Cobb broiler (CB) populations. Four variants were detected in the chicken GJA1 gene, in which one synonymous mutation was l...

Ascariasis is very common in indigenous chicken causing retarded growth, low productivity and mortality. Considering the problem of Ascaridia galli in chicken, anthelmintic resistance, high cost and human health hazard of chemical anthelmintic the use of medicinal plant is an alternative choice. An experiment was conducted in the Department of Pharmacology, Bangladesh Agricultural University, M...

A study was conducted to find out the differences in carcass traits among the Cobb-400, Vanraja, Aseel and Kadaknath Breeds of chicken. Cobb-400 showed significantly (P<0.05) higher live weight and dressing percentage than indigenous breeds (Vanrja, Aseel and Kadaknath) at the age of six week. Hot carcass weight as well as cold carcass weight were significantly (P<0.05) higher in comparison to ...
