  Journal of Dairy & Veterinary Sciences Abstract Sustainability, animal welfare, environmental and climate concerns and awareness of social responsibility towards the community have increased consumers interest in knowing how, where and by whom food is produced and handled on its way from the farm to the table. This constitutes a business opportunity for farmers as a growing number of consumers want to buy food, produced locally or regionally directly or under farm certification schemes whereby acceptable animal welfare conditions play often an important role. Farming systems for dairy cows, including housing and management conditions, are important factors affecting their health and other aspects of their welfare, partly through housing and equipment and partly through management and handling practices. Importance of European Food Safety Authority (EFSA) The panel on Animal Health and Animal Welfare (AHAW) is a scientific advice on all aspects of animal diseases and welfare of fo

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The neonatal phase of calves is a phase that needs extra care due to newborns’ vulnerability. Enteritis - an inflammation of the intestinal mucosa, resulting mainly in diarrhea - stands out among the conditions that affect animals in this period. Enteritis are responsible for huge losses in cattle breeding, especially in the early stages of rearing. Besides the losses caused by mortality, there are also expenses with veterinarians, treatments and decreased performance of the animal throughout its productive life. The present study aimed to perform a review of diarrhea in newborn calves.

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract Evaluation of the concentrations of the sperm macromolecule called proAKAP4, has been successfully introduced as a pertinent sperm parameter to assess sperm quality and high concentrations of proAKAP4 was shown to be highly correlated with sperm motility and fertility in large mammals. The sandwich ELISA kits known as Pig 4MID® Kits allowed the artificial insemination stations to monitor sperm quality more accurately with threshold values qualifying each ejaculate and animal. Introducing new methods and procedures are always challenging and sperm frozen collections have been suggested to standardize sperm assessment in daily routine. We thus have designed an experimental study to assess proAKAP4 stability and integrity in neat frozen ejaculates. Following baseline measurements, fresh ejaculates were aliquoted and stored at -20 °C for stability experiments up to 6 months and following up to 10 freeze-thawing cycl
