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), ...

Arginine and methionine transport by Aspergillus nidulans mycelium was investigated. A single uptake system is responsible for the transport of arginine, lysine and ornithine. Transport is energy-dependent and specific for these basic amino acids. The Km value for arginine is 1 X 10(-5) M, and Vmax is 2-8 nmol/mg dry wt/min; Km for lysine is 8 X 10(-6) M; Kt for lysine as inhibitor of arginine ...

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...
