Rearing & Weaning

Body length as an objective marker of time to wean in laboratory mice

In laboratory mice, the 21-day weaning standard is the most commonly applied strategy across institutions. However, this strategy has numerous drawbacks, including potential for litter overlap, pup mortality, and weaning extensions. In pursuit of a more objective marker for weaning,...

Welfare of calves and heifers on dairy farms with cow-calf contact rearing or early separation

Early separation (ES) of cow and calf in dairy farming is increasingly questioned due to implications on animal welfare. The aim of this study was to compare the welfare of animals on commercial dairy farms with cow-calf contact (CCC) or...

A scoping review on pair housing dairy calves: Health and performance outcomes and tactics to reduce cross-sucking behavior

Calves raised in pairs or triplets often experience better growth performance outcomes when compared to their individually housed peers. However, veterinarians may be concerned that pair housing compromises calf health, and producers are concerned about abnormal oral behavior (e.g., cross-sucking)....

Editorial: Fish welfare in aquaculture and research—where are we going?

Rapid technical developments are taking place in aquaculture, and its production is increasing globally every year by more than 4%. Research is the necessary foundation for politics to define reasonable regulations and recommend guidelines for aquaculture, but also the basis...

Impact of early social housing on the play behavior of neonatal and post-weaning dairy calves

We aimed to assess the impact of early life housing and play experiences on neonatal and weaned calves play behavior. A total of 96 female dairy calves were recruited from four Scottish dairy farms and assigned to individual (n =...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Lambs cope better with gradual weaning and definitive maternal separation when housed with known-adult companion ewes

Gradual weaning reduces lambs’ distress during definitive maternal separation by progressively decreasing milk intake and maternal contact. However, repeated temporary separation during gradual weaning, followed by definitive separation, remains stressful and negatively impacts lamb behavior, immune function, and overall physiological...

The effects of cow-calf-contact rearing on dairy animals’ social traits – a pilot study

Early separation of the calf from the dam, mostly within 24 h after birth, is common for dairy cows, but cow-calf contact (CCC) rearing gets increasing interest from both practice and science. CCC rearing allows calves suckling their dam or foster...
