Dairy cows enter the negative energy balance in the early post-partum period, which negatively affects milk yield, health status and reproduction. This study aimed to determine if milk yield (MY) and fat/protein (F/P) ratio could be used as reliable

Despite the routine use of cryopreservation in dairy cattle, the subsequent deterioration in the quality of bull insemination doses (IDs) is an incentive to refine cryopreservation protocols, including the composition of the ID. The aim of this study

There are still concerns over sperm quality when plant-based diluents are used instead of animal-based semen extenders. Therefore, in our study we compared the effects of one soybean lecithin-based (AndroMed®) and two egg yolk-based (BullXcell® and
