Sixty layers (50 weeks of age) each of native Desi, Fayoumi and commercial White Leghorn (Nick Chick) were kept in wire cages following completely randomized design for 8 weeks during summer season (June and July). The birds of each type were divided into two groups i.e. with and without supplementation of vitamin C with three replicates assigned to each layer group (10 birds in each replicate)...

Biosecurity and sustainability in poultry production requires reliable germplasm conservation. Germplasm conservation in poultry is more challenging in comparison to other livestock species. Embryo cryopreservation is not feasible for egg-laying animals, and chicken semen conservation has variable success for different chicken breeds. A potential solution is the cryopreservation of the committe...

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...

The main dietary guidelines recommend restricting total and saturated fat intake in the management of high blood cholesterol levels for cardiovascular risk. These recommendations are usually oversimplified by considering that all red meats should be limited and replaced by white meats. However, lean red meat can be as low in fat as white meat. We examined the effects of red meat (lean breed lam...

Background and Aim: IPB-D2 chickens are selected from IPB-D1 due to their disease-resistance characteristics. One-way evaluate the strength of a chicken’s immune system is by examining number circulating T lymphocytes. This assessment can be conducted using modern analytic method called flow cytometry which relies on monoclonal antibodies detect relative proportions each cell measure quality qu...

Insulin-like growth factor binding protein 2 regulates a broad spectrum of biological activities involved in growth, development, and differentiation. The current study was designed to investigate the associations of IGFBP2 gene polymorphisms with chicken growth and body composition traits. The Northeast Agricultural University Resource Population (NEAURP) was established by crossing broiler si...

UNLABELLED Chicken whole-genome gene expression arrays were used to analyze the host response to infection by infectious bursal disease virus (IBDV). Spleen and bursal tissue were examined from control and infected birds at 2, 3, and 4 days postinfection from two lines that differ in their resistance to IBDV infection. The host response was evaluated over this period, and differences between su...

Intramuscular fat (IMF) plays an important role in meat quality. However, the molecular mechanisms underlying IMF deposition in skeletal muscle have not been addressed for the sex-linked dwarf (SLD) chicken. In this study, potential candidate genes and signaling pathways related to IMF deposition in chicken leg muscle tissue were characterized using gene expression profiling of both 7-week-old ...
