the present study conducted to investigate the effect of energy sources and levels on performance and breast meat amino acids profile in cobb 500 broiler chicks. a total of 600 1-day-old cobb 500 broiler chicks with an average weight of 39 ± 0.50 g were randomly divided into five treatments. each treatment was further divided into four replicates. chicks were fed a basal diet based on corn and ...

the aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of ross 308 broiler chicks. fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), ...

abstract bee venom is a complex mixture of proteins, peptides and low molecular components: proteins (enzymes) :( phospholipase, a2phospholipase b, hyaluronidase α – glucosidase) - , peptides (melittin, apamine mcd peptide,adolapine ,procamine a and b, protease inhibitors)- low molecular components: biogenic amines:( histamine, dopamine and noradrenalin) - pheromones: complex ethers- sugars :( ...

In this paper, the ultrasonic absorption of amino acids was measured using a small cylindrical resonator at physiological pH and 25°C and a concentration of 0.1. M. The absorption of mixtures of some amino acids was also measured. In the case of cysteine-histidine, the absorption of mixtures is much larger (more than twice) than the summation of absorption of the individual amino acid. This...

a study was conducted to determine the effects of diet formulation on arian broiler breeder performance in their 50 to 64 wks of age. one hundred and sixty eight female and 24 male breeders were employed in 8 treatments of 3 replicates (7 females plus a male) in a completely randomized design (a factorial experience of 2 × 2 × 2). eight experimental diets were formulated based on three factors,...

caviar is one of the valuable and most popular fish products all over the world that are obtained from sturgeons. nowadays, the wild resources of these fishes are diminished, therefore, to meet the demand for the product, farming sturgeons has been considered. the chemical composition and the amino acids profiles of the wild and farmed roe obtained from beluga (huso huso) were compared and the ...

Early development of the digestive tract is crucial for achieving maximal growth and development of chickens. This study examined the effects of in ovo (IO) feeding of 0.70 mL of dextrose (10.00% and 20.00%) or amino acids solutions into the yolk sac at day 14 of incubation on small intestine histomorphometry and histomorphology, intestinal development, hatchability, body weight, and l...
