Safety of a feed additive consisting of potassium ferrocyanide for all animal species (K+S Kali GmbH). [PDF]

EFSA J
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety of a feed additive consisting of potassium ferrocyanide for all animal species. In a previous assessment the FEEDAP Panel concluded that, in the absence of a margin of safety, the use of potassium chloride supplemented with the ...

Effects of an optimized dairy calf-rearing protocol on performance and health in the subsequent fattening period on Swiss veal farms [PDF]

Veterinary and Animal Science
We conducted a prospective field study to characterize the effects of an optimized rearing protocol of calves on dairy-farms on the subsequent performance, health and antimicrobial use (AMU) at the veal-farm. On 19 dairy-farms a total of 55 matched pairs

Trends in Veterinary Drug Residues in US Cattle: Analysing USDA Sampling Data. [PDF]

Vet Med Sci
National US residue monitoring data (2021–2023) were analysed to characterise veterinary drug residue detections in cattle. Detection patterns varied by cattle type, with dairy cows accounting for the highest number of detections and a consistent group of commonly used drugs responsible for most violative and non‐violative findings.

The future of surplus dairy calves – an animal welfare perspective

Frontiers in Animal Science, 2023
An important obstacle toward sustainably produced animal-source food is the existence of so-called ‘surplus animals’, which are by-products of the production of dairy products and eggs, and ‘unwanted’ due to their perceived low value.
