Classical quantitative trait loci (QTL) analysis and gene expression QTL (eQTL) were combined to identify the causal gene (or QTG) underlying a highly significant QTL controlling the variation of breast meat color in a F2 cross between divergent high-growth (HG) and low-growth (LG) chicken lines. Within this meat quality QTL, BCMO1 (Accession number GenBank: AJ271386), encoding the β-carotene 1...

Guanidino acetic acid (GAA) is naturally occurring in animal tissues playing a major role in the energy metabolism as a precursor of creatine. The objective of the study was to examine potential effects of GAA (CreAMINOTM) supplementation in purely vegetable diets compared to a positive control. Therefore a total of 780 male ROSS 308 broiler chickens were assigned to one of the following three ...

The global poultry industry has been faced with emerging broiler breast meat quality issues including conditions known as white striping (WS, white striations parallel to muscle fibers) and woody breast (WB, hardness of raw fillet). Experiments were conducted to evaluate effects of WS and WB hardness on meat quality traits in broiler breast fillets. In Exp. 1, birds were processed at approximat...

The objective of this study was to determine if a diet supplemented simultaneously with vitamins C and E would alleviate the negative effects of heat stress, applied between 28 and 42 days of age, on performance, carcass and meat quality traits of broiler chickens. A total of 384 male broiler chickens were assigned to a completely randomized design, with a 2×3 factorial arrangement (diet with o...

Background: One of the concerns of consumers of animal protein sources is the residues of heavy metals in meat. The accumulation of these elements in meat and the consumption by humans can cause acute and chronic disorders in the function of vital organs. Methods: For the estimation of cadmium, zinc and silver in the poultry meat products, 100 samples of chicken breasts, thighs, hearts and liv...

A respective number of pigeon and quail were purchased from Churkhai Bazar, Mymensingh at their marketing weight to compare yield quality characteristics meat. The birds then slaughtered the meat compared against live weight. samples breast, thigh drumstick kept 4°C for 24 hours. Findings reveal that thigh, drumstick, head, liver, gizzard, heart, neck shank% significantly higher in but feather ...

Over the past 50 years the worldwide growing demand of poultry meat has resulted in pressure on breeders, nutritionists and growers to increase the growth rate of birds, feed efficiency, size of breast muscle and reduction in abdominal fatness. Moreover, the shift toward further processed products has emphasized the necessity for higher standards in poultry meat to improve sensory characteristi...
