EFFECT OF IN OVO NANOPARTICLES AND AMINO ACIDS INJECTION ON JAPANESE QUAIL PERFORMANCE

Abstract

The present study was carried out at the Quail Production Unit, Agricultural Experiments and Research Station at Shalaqan city, Faculty of Agriculture, Ain Shams University Farm, under the Egyptian conditions, during the period from May to October, 2017. The main objective of the study was to determine the effect of in ovo administration of Nano-Selenium (Nano-Se) and Glutamine (Gln) on hatchability, post hatch performance, carcass traits and some blood biochemical traits, under the prevailing conditions in Egypt. A total number of 600 eggs with an average weight of 12 gm, obtained from a 12 weeks old Japanese quail breeder flock, were used in this study. A day before setting in the incubator, eggs were numbered, weighed individually and randomly divided into five experimental groups each of 120 eggs with three replicates (40 eggs each). Eggs were subjected to injection in air cell just before incubation as follows: The 1st group (T1) was used as a negative control and not injected. The 2nd group (T2) was considered as a positive control and injected with bovine serum albumin (BSA) that was used to dissolve Nano-Selenium. The 3rd (T3), 4th (T4) and 5th (T5) groups were received Nano-Se (2.5 ppb/egg), Glutamine (20 ppm/egg) and Glutamine (10 ppm/egg), respectively.
