The Effect of Selection According to Live Weight on Fattening Performance in Obtained Progeny in Different Genotype Breeding Japanese Quails

Abstract

This research was planned to determine the fattening performance in progeny obtained from quails with different genotypic structures. Two genotypes, one commercial (T) and one Japanese quail (CU) reared at Çukurova University, were used in the experiment. 500 chicks were obtained from both genotypes at the end of hatching. After the quails obtained were grown for 5 weeks, the selection was made according to live weight. Thus, 6 different experimental groups, 2 control (TK, CUK), 2 selection (TS, CUS) and 2 hybrids (TM, CUM) were formed in the trial. 72 breeding quails were selected from each experimental group and a total of 432 animals were used. Broiler feed containing 22% crude protein and 3000 kcal/kg ME was used for feeding the progeny. Weekly live weight, feed consumption, feed conversion ratio, live weight gain and carcass characteristics at the end of 5 weeks were investigated in progeny obtained from breeders. According to the findings obtained from the study; It was found that the differences observed in terms of live weight gain in progeny were not significant (P>0.05). It was observed that the differences observed between the groups in the 1st and 2nd weeks were significant in terms of feed conversion ratio, and it was determined that the Çukurova selection group was the best in these weeks (P<0.05). It was found that the differences observed between the groups in terms of carcass characteristics except for the stony and inedible parts were significant (P<0.05). As a result, it can be said that the Çukurova group and hybrids are better in fattening performance.
