Biomarker responses to weaning stress in beef calves.
The study objective was to investigate the physiological effects of weaning on beef calves and identify a panel of blood-based welfare biomarkers. On the day (d) of weaning (d 0), 16 spring-born, single-suckled, beef bull calves that previously grazed with their dams at pasture, were assigned to one of two treatments: (1) control (n = 8), calves were loose-housed with their dam, (2) weaned (n =...
متن کاملEarly weaning beef calves.
Early weaning is a management practice that reduces grazing pressure on pastures by decreasing the nutrient requirements of cows. Calves that are weaned early are relatively efficient at converting feed to gain, and can weigh as much, or more than, calves allowed to remain with their dams until a conventional weaning age is reached. Balanced diets with excellent physical, chemical, and palatabi...
متن کاملMinimising the stress of weaning of beef calves: a review
Weaning of beef calves is usually done abruptly and early compared to the natural weaning of the species, and is associated with simultaneous exposure of calves to a range of social and environmental stressors. Behavioural and physiological responses to weaning indicate detrimental effects on the welfare of these animals. The development and assessment of weaning methods aiming at reducing or a...
متن کاملThe effect of early weaning on feedlot performance and measures of stress in beef calves.
Forty crossbred steers (Brahman x English) were categorized into two groups: 1) early weaned (EW; n = 20); and 2) normal weaned (NW; n = 20). Calves were 89 and 300 d of age at the time of EW and NW, respectively; SEM = 4.4. Early-weaned calves were kept on-site (University of Florida, Ona), provided supplement (1% of BW), and grazed on annual and perennial pastures until NW. At the time of nor...
متن کاملWeaning Strategies in Beef Cattle to Reduce Stress
Weaning is considered one of the most stressful periods in the beef production system for beef calves. During this process calves are subjected to a variety of stressors including removal from their mothers, new diets, processing (vaccination, dehorning, castration etc.), and possibly even new pen or pasture environments. These stressors, singly or in combination, can result in behavior or phys...
