dc.description.abstractBirth and weaning weights, average daily weight gain, and Kleiber ratio are important indicator traits in selection decision. The phenotypic expression of these traits is determined by the genetic background, environmental effects, and their interactions. The objective of this study was to estimate genetic parameters regarding birth (BW) and weaning weights (WW) and average daily weight gain (ADWG), Kleiber ratio (KR), and obtain the effects of sex, birth type, herd, and year. The data consisted of 2274 Kilis goats with pedigree information obtained from 53 bucks and 774 does in 4 generations. The restricted maximum likelihood (REML) procedure was conducted with an animal linear mixed model. Sex, birth type, herd, and year were found to be statistically significant (p value < 0.001) for all traits. Moderate direct heritabilities (h(a)(2)) for BW, WW, ADW, and KR were found to be as 0.18 +/- 0.03, 0.50 +/- 0.04, 0.47 +/- 0.04, and 0.37 +/- 0.05, respectively. The proportion of maternal permanent environmental effect (c(2)) to the total phenotypic variance (sigma(2)(p)) was estimated as 0.00 +/- 0.00, 0.12 +/- 0.02, 0.11 +/- 0.02, and 0.18 +/- 0.03 for BW, WW, ADWG, and KR, respectively. The genetic, phenotypic, and environmental correlations between the pre-weaning growth traits were found to be ranging from - 0.02 to 0.99. Thus, our study suggests moderate heritabilities and positive and relatively high genetic correlations among the observed pre-weaning growth traits. These results have implications in terms of providing rapid genetic progress for these traits in breeding programs of Kilis goats.en_US
