The aim of this study is to evaluate different aspects regarding culled cattle and to suggest operating procedures for their correct management. Information collected in Piedmont region allowed for an assessment of the number of cattle put down on the farm, a quantification of slaughters performed in urgency and emergency (SUS/SES) and a headcount of those which died during farming. The survey highlighted the limited use of euthanasia or putting down compared to the number of cases of SUS/SES which were approximately ten times higher. If cattle displays severe health problems, such as a multifactorial disease like downer cow, the farmer has to decide rapidly the treatment to avoid cattle distress. A checklist has been developed and a flow chart has been revised to assist farmers and vets to quicken the decision-taking process and to manage the cattle in a more efficient manner. During this study a number of different problems have been stressed out. Particularly, the shortcomings in the training of operators commissioned to manage the animals, the inadequacy of structures used for the sheltering and slaughter of bovines on the farm, and differences in the operating procedures for culled cattle across the territory. From the obtained results, we can conclude that it is necessary to adopt a transversal approach, so that the information regarding these animals (welfare, health status, drug treatments and destination) will be uniform and adequate during all the steps of production, to ensure animal welfare and food safety.

Unlabelled: Bovine herpesvirus (BoHV) infection poses a significant threat to the healthy development of the cattle industry. BoHV-1 primarily causes infectious bovine rhinotracheitis, while BoHV-5 is associated with bovine necrotic meningoencephalitis. These two pathogens not only exhibit a high correlation in antigenicity and genetic background but, more importantly, can establish latent infections within the bovine ganglion.

Epizootic hemorrhagic disease (EHD) is a non-contagious viral infection that can cause important economic losses in dairy farms. This study aimed to identify epidemiological and genetic factors influencing the susceptibility and severity of EHD in Holstein dairy cattle during the 2023 outbreak in Spain. Data from 2852 animals in 7 affected farms from 5 Spanish provinces were used.

This article addresses infectious reproductive diseases in cattle, which can significantly impact production and profit on cattle operations. It highlights vital biosecurity practices aimed at minimizing the introduction of reproductive pathogens into breeding herds, including the importance of maintaining records, implementing a defined breeding season, culling nonproductive animals, quarantining and testing imported livestock, and the use of vaccines to maximize herd immunity. The article focuses on economically important reproductive pathogens of cattle from a biosecurity standpoint, focusing on mitigating the introduction and impact of reproductive diseases in cattle.

B vitamins, including niacin (vitamin B), are synthesized by rumen microbes, but supplementation may provide additional benefits for ruminant health and productivity. Supplementing rumen-protected niacin (RPN) during the transition period can reduce lipolysis after calving and, consequently, may improve health and fertility of dairy cattle later in lactation. Our objective was to determine if supplementing RPN during the first 21 DIM would improve the health of dairy cows on a commercial dairy farm.

Udder cleft dermatitis (UCD) is a common dermatological condition of the udder skin in dairy cows. It is generally considered to be a multifactorial disease, being described in a rather limited amount of literature. Its cow and within-herd prevalence widely ranges between studies depending on the study characteristics, environment and breed.
