Changes in plasma volatile fatty acids in response to weaning and feed intake in young calves.
Effects of weaning age on plasma VFA were examined using 16 Holstein heifer calves. Animals entered the study at 6 +/- 3.5 d of age and were fed 1.8 kg milk twice daily to 28 (early weaning) or 56 d (late weaning) and a commercial pelleted calf starter from 0 (early) or 28 (late) d. Blood was sampled once weekly for 14 wk. Total blood concentrations of VFA, acetate, propionate, and butyrate wer...
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...

Effects of weaning age on blood glucose, ketones, and nonesterified fatty acids were examined using 16 Holstein heifer calves. Animals entered the study at 6 +/- 3.5 d of age and were fed 1.8 kg of milk twice daily to 28 (early weaning) or 56 d (late weaning) and a commercial pelleted calf starter from 0 (early) or 28 d (late). Blood was sampled once weekly for 14 wk and analyzed for beta-hydro...
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 کاملEffect of feed and(or) water deprivation prior to weaning on reproductive performance of sows: a cooperative study.
A total of 292 sows, at three experimental stations (Auburn, Texas A&M, Texas Tech), was used to determine the effects of depriving sows of feed and(or) water before weaning on reproductive performance. The four treatments were arranged as a 2 X 2 factorial to evaluate two periods of feed deprivation (0 and 48 h) and two periods of water deprivation (0 and 24 h) before weaning. Sows were allowe...
