Effects of the addition of different egg yolk amountsto skimmilk extenders on post-thaw spermatological characteristics
2 Tarım ve Köyişleri Bakanlığı, İstanbul İl Müdürlüğü - In this study, the bull semen collected from 5 Holstein bulls were extended with skimmilk which conta1ned 0 %, 5 %, 10 % and 20 % egg-yolk and frozen in straws. Before freezing and post-thawing, motility and morphological abnormal rates were examined, and de termined as similar. Fertility rates gained from 220 inseminations were not different among extenders. The difference was not important statistically. Keywords :
