Ebeveynlerin bazı özelliklerinin kuluçka ve etlik piliç performansına etkisi
Özet
Consists of 100 male parents in the Ross 308 genotype determined in small, standard and large pens in the 6th week of growing period. In the 18th week of growing, 5 male from each group were selected for the production period, as smaller (KK) and standard (KS) weight from small pen, standard (SS) weight from standard pen, standard (BS) and larger (BB) from large pen. The study was carried out to investigate incubation results and broiler performance of these males at different periods (24-Young, 35-Middle and 48-Old) in artificial insemination with standard weight females. While there was a significant difference between groups in terms of fertility rate in the first study (p<0.05), it was not clear in other studies and generally there was no difference between the groups in terms of hatchability of fertile eggs and hatchability (p>0.05). When the broiler performance characteristics were analyzed; it was calculated that BB group, which was the highest average in terms of body weight (p<0.05). Although the ranking of the other groups varies according to sir age, the KS group had the lowest average in general (p<0.05). In addition to weight BB group broilers were also advantage in terms of FCR (p<0.05). BB group broilers reached the highest values according to the mean of EPEI, where performance criteria such as BW, FCR and liveability were evaluated together (p<0.05). As a result, it was determined that it was impossible to choose PS males according to the male body weights only in the 6th week and being at the standart weight negatively affects broiler performance. It is suggested that BB group males can be preferred for the production of heavier and economical broilers.
