Non-infectious infertility is particularly critical for sire rams/bucks, as seasonal breeders. This seasonal heavy use of males may lead to sexual exhaustion such that the regular semen production, libido, ejaculation, and litter yield can be seriously impaired. In severe cases, the reproductive processes may stop completely. For avoiding infertili...

Türkiye, özellikle koyun sütü üretiminde (dünyada 1.), koyun (dünyada 7.) ve küçükbaş (Avrupa'da 1.) popülasyonuyla (2020) dünya çapında söz sahibi olan bir ülkedir.

In the literature, there is a wide range of information about infectious infertility (decrease in reproductive performance or litter productivity), due to a certain microbial factor, in different breeds of breeding animals. Also, regarding infertility cases in animals, dairy breeding females (eg. Holstein/Simmental cow, Chios ewe, and Saanen doe) c...

The most important factors affecting the success of artificial insemination are the balanced nutrition of the animals and the determination of estrus. Malnutrition causes a decrease in the Body Condition Score (BCS). Low BCS affects the deterioration of the metabolism of cows which has a primary influence on estrus and offspring productivity. In th...
