Early 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 کاملEarly Weaning Beef Calves at 70 to 90 Days of Age An overview of recent research
The benefits of early weaning during instances of environmental strain, usually witnessed by a shortage of summer forage, has been understood and practiced for many years. However, the use of early weaning as a normal, annual management practice for beef cows is not common. Our interest in the topic originated from the common production practice in the Southeast, which allowed heifers to develo...
متن کاملBiomarker 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 alters the acute-phase reaction to an endotoxin challenge in beef calves.
Previous research indicates that early weaning before shipment can reduce transportation-induced increases in acute-phase proteins (APP) and can increase feedlot performance in beef calves. These data suggest that the combination of weaning and transport stress may compromise the immune system of calves, thus hindering subsequent performance and health. Therefore, our objective was to determine...
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...
