Twenty yearling Angus, Hereford, and Angus-Hereford crossbred heifers and 20 two-year-old Hereford heifers were individually fed rations consisting of different levels of protein but similar amounts of energy, minerals, and vitamins. Five heifers of each age were alloted per group and fed for a period of 159 to 207 days, depending on reproduction performance. Yearling heifers, initially weighing about 500 pounds, with a daily consumption of 1.06, 0.65, 0.28, and 0.08 pound crude protein, gained 0.94, 0.70, 0.01, and - 0.72 pound per day, respectively. Two-year-old heifers, initially weighing 675 pounds, consuming 1.34, 1.06, 0.71, and 0.62 pound crude protein daily, gained 0.75, 0.52, - 0.07, and - 0.23 pound per day, respectively. The differences obtained in the performance between the year-ling and two-year-old heifers were due in part to age and weight differences, as well as source of energy and level of TDN and protein intake. The nutritional stress due to a low protein intake decreased appetite and rate of gain... |
