Genetic Parameter Estimation for Plasma Biomarkers Associated With Energy Reserves During Critical Physiological Stages in Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The ability of ruminants to mobilise and restore body reserves (BR) over time, referred to as BR dynamics, is currently considered an interesting biological component to be included in breeding programs targeting enhanced BR resilience. However, genetic studies of proxies for BR levels and BRD remain scarce, particularly in small ruminants ...

Precocial Weaning Influences Anxiety, Social and Maternal Care but Not Cognition in African Striped Mice, Rhabdomys dilectus chakae

Developmental Psychobiology, Volume 68, Issue 2, March 2026.
ABSTRACT Weaning is a stressful stage in the lives of young mammals. Early weaning, in particular, can lead to long‐lasting physiological and psychological changes. We investigated the effects of precocial weaning on anxiety, social behavior, cognition, and maternal behavior in adult African four‐striped mice (Rhabdomys dilectus chakae). Mice weaned at

Dairy calves suckled by their dam: which compromise between calf growth, milk production and animal welfare?

, 2022
In dairy farms, early separation of calves is a common practice that is becoming increasingly controversial. Two trials were set up to test three rearing practices that allow to maintain the calves with their dam during the day (9am-5pm), up to 3 weeks of age or up to weaning, and compared to calves fed from an automatic milk dispenser.

Scientific Opinion on the safety and efficacy of vitamin D3 (cholecalciferol) as a feed additive for chickens for fattening, turkeys, other poultry, pigs, piglets (suckling), calves for rearing, calves for fattening, bovines, ovines, equines, fish and other animal species or categories, based on a dossier submitted by DSM [PDF]

EFSA Journal, 2012
The principal physiological role of vitamin D in all vertebrates is in calcium and phosphorus homeostasis. The classic clinical deficiency syndrome is rickets. The FEEDAP Panel notes that for turkeys for fattening, equines, bovines, ovines and pigs the maximum content for vitamin D3 in feed does not provide any margin of safety, and that, except for ...

Effect of suckler cow breed type and parity on the development of the cow-calf bond post-partum and calf passive immunity

Irish Veterinary Journal
Background Development of the cow-calf bond post-partum and passive immunity of calves from spring-calving beef × beef (B×B) and beef × dairy (B×D) cow genotypes was determined using primiparous and multiparous (Experiment 1), and primiparous and second ...
