چکیده

lysozyme is one of the bioactive components of eggs with well known antibacterial potential, widely used in food industry, medicine and pharmaceutics. in this study, the possibility of quail’s egg lysozyme concentration and activity (modified via amino acids dietary supplementation) was investigated. in accordance with lysozyme amino acids profile, four amino acids of: asparagine, arginine, glycine, and methionine were added to layer quails’ feed. for supplementation of amino acids, provision of the same level of protein content in all the groups was considered, so that amino acids were supplemented in such a way as to add 0.235% protein to the basal diet. a total of 72 japanese quails were employed in a completely randomized design experiment of six experimental groups, three replicates and four birds in each of the 18 cages. amino acids supplementation was proved to have significant increasing effect on egg number and on total egg,s mass production (p

Effect of Dietary Supplementation of Withania Somnifera on Egg Production and Egg Quality Parameters in Japanese Quails

An experiment was conducted on laying quails to determine optimum dietary level of Ashwagandha supplementation on egg production and egg quality traits at Instructional poultry farm Nagla, GBPUA&T. Hundred quails were randomly distributed in four treatments and reared on standard managemental conditions. The root powder of Ashwagandha was added over the basal ration at 0.5% level (T2), 1% (T3),...

Amino acid sequence studies on bobwhite quail egg white lysozyme.

To test the immunological prediction that there should be two amino acid sequence differences between the lysozymes of the bobwhite quail and the chicken, the sequences of these two lysozymes have now been compared. Lysozyme purified from bobwhite quail egg white was reduced, carboxymethylated, and digested with trypsin. The resulting 18 peptides were separated and their compositions determined...

Kisspeptin-10 Enhanced Egg Production in Quails Associated with the Increase of Triglyceride Synthesis in Liver

Our previous results showed that kisspeptin-10 (Kp-10) injections via intraperitoneal (i.p.) once daily for three weeks notably promoted the egg laying rate in quails. In order to investigate the mechanism behind the effects of Kp-10 on enhancing the egg laying rate in birds, this study focused on the alternations of lipids synthesis in liver after Kp-10 injections. 75 female quails (22 d of ag...
