In-ovo Effects of Lysine Amino Acid on Histomorphometry of Thigh Muscles, Cecal Tonsils and pH in Japanese Quail

Abstract

The current was carried out to investigate the in-ovo effect of lysine on the histology of Thai muscles, their pH and Cecal tonsil in the Japanese quails. At 1^st day of hatching, total number of 240 quail eggs was injected with four different solutions. G-1^st was kept as control and injected with sterile distilled water. G-2^nd was injected with 1g/50 ml sterile distilled water solution of lysine. G-3^rd was injected with 2g/50 ml sterile distilled water solution of lysine. G-4^th was injected with 3g/50 ml sterile distilled water solution of lysine. In-ovo treated eggs hatched at 17^th day. Birds after hatching divided into four groups. All the birds of four groups reared on the same diet.  Three birds per replicate (n=05) were selected for slaughtering and samples were collected for histological analysis. In-ovo inoculation of lysine at the level of 3g/50 ml sterile distilled water solution has considered more beneficial effects on the histo-morphometry of cecal tonsils, thai muscles. Improvement in the histology of cecal tonsils indicated the immunity level and thai muscles indicating the muscles growth and meat quality of quail birds.
