Özet
This study aimed at comparative investigation of estrus, pregnancy, mating performance, behaviors, and kid yield at birth in different goat genotypes. The study was carried out at the Technological and Agricultural Research Centre of Canakkale Onsekiz Mart University for a period of two years. Although the courtship behavior index of females did not differ, the bucks of Gokceada had lower courtship behavior index and jumping frequency with ejaculation than did other genotypes (P <= 0.05). Maltese bucks displayed courtship behavior index and mounting frequency with ejaculation similar to Turkish Saanen bucks, but had lower mounting frequency without ejaculation (P <= 0.05). First estrus and birth rates (buck under) were 33% and 25% for Gokceada, 65% and 42% for Maltese and 96% and 64% for Turkish Saanen, respectively (P<0.0001). The period between buck introduction and first estrus or conception increased in all genotypes in the second year of the study. Gokceada had longer periods and lower return rates in both years (P <= 0.05). Kid yield per goat at birth in the second year increased significantly in Gokceada and Maltese genotypes and was found as Maltese (1.9; 2.4), Turkish Saanen (1.9; 1.8) and Gokceada (1.6; 1.8) in the descending order.
