Abstract
The objective of this work was to evaluate the effects of increasing the contents of total solids (TS) in whole milk, by adding increasing amounts of milk replacer powder, on the behavior of dairy heifers. Holstein-Gyr crossbred heifers (n = 60) were distributed in four treatments: 13.5, 16.1, 18.2, and 20.4% TS. From 5 to 55 days of age, heifers received 6 L per day of liquid feed, which was reduced by half from 56 to 59 days. Heifers were weaned at 60 days of age and monitored until 90 days, and their behavior was evaluated weekly. During gradual weaning and after weaning, heifer behavior was recorded 1 hour before and 1 hour after liquid feed was offered, and, during weaning, it was evaluated by the scan method. Heifers fed liquid feed containing 20.4% TS present a higher number of play behaviors, spent less time standing, and spent more time ruminating than those that received liquid feed with 13.5% TS, indicating that a higher nutritional plan during weaning is an effective strategy to reduce stress in this period. |
