Description
Summary:ABSTRACT The present study was aimed at studying the influence of seasonal parameters (ambient temperature, atmospheric pressure, air humidity, duration and gradient of daylight hours) on the quantitative and qualitative parameters of sperm (volume, motility, concentration, survival) of rams bred in mid-latitude. Sperm samples were collected from 5 Dzhalginsky merino rams once a week for twelve calendar months using an artificial vagina. The lowest quality sperm was produced in the spring, high quality indicators were observed in the autumn period (semen volume: 0.96 ± 0.14 ml versus 1.42 ± 0.15 ml, P
