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 کاملEffects of lasalocid on selected ruminal and blood metabolites in young calves.
Twelve Holstein bull calves were ruminally cannulated at 5 d of age and assigned to 0 or 1 mg of lasalocid/kg of BW daily, administered postruminally via milk replacer or into the ruminal cannula. Calves were fed milk replacer for 8 wk and calf starter for 12 wk. Lasalocid administration was terminated at weaning in calves fed lasalocid in milk replacer.
