  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 o...

  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. Keywords: Neonatal diarrhea; Infectious agents; Dairy cattle Abbrevations: ETEC: E. coli enterotoxigenic; EHEC: E. coli enterohemorragic; BVDV: Bovine Viral Diarrhea Virus Introduction The neonatal period in cattle - that goes from birth to 28 days of age - is especially important from a health point of view, since approximat...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract In order to determine the phytochemical and bromatologic components of S. nigrum L., plant widely used as medicine and food for the population in the Huambo province, in Angola, young leaves were harvested in the morning period. They were subsequently put to dry in shade for 15 days, mashed in a traditional mortar and passed through a sieve to reduce them in finer powder. 500g of leaves powder were sent to National Center for Animal and Plant Health in Cuba (CENSA) for the determination of secondary metabolites and bromatologic analisis. Qualitative phytochemical analysis were performed using the Rondina and Coussio methodology (1969), the bromatologic trials by the Kjeldahl methods and thermogravimetric balance was used for dry matter and moisture calculation. Tannins, alkaloids, flavonoids, primary and secondary amines, leucoanthocyanidins, free phenols and triterpenes and or steroids were identified. In t...

  Journal of Dairy & Veterinary Sciences - Juniper Publishers Abstract The availability of indicators that would help to avoid the overvaluation of one of the characteristics involved in the assessment of a good dairy cow over others that are important as well would also allow identifying the most adapted biotypes to the different environments existing at the place of the evaluation This article aims to discuss the need to use several productive and reproductive indicators when measuring the biological efficiency of a dairy cow in grazing systems. It was used retrospective data corresponding to the lactations of 300 primiparous and multiparous cows of the Holstein breed - American-Canadian biotype, along with records of their entire productive life, from their incorporation into the system until their sale or death. The animals were divided into two categories: pure cows (PC, n = 120) and cows in the breeding record (CBR, n = 180). It is observed that there are two different st...
