Effect of age at weaning and fiber level in the diet on performance of early-weaned beef calves


, : Effect of age at weaning and fiber level in the diet on performance of early-weaned beef calves. Revista Argentina de Produccion Animal 22(1): 1-13

In experiment 1, 72 calves, 55-80 days old, were grouped into two weight categories: WGT1=71+or-4.08 kg and WGT2=92+or-5.23 kg. Three diets were imposed on each group: DIET1+energy-protein concentrate (CONC)+alfalfa hay; DIET2=CONC+oats hay and DIET3=CONC+oats silage. Diets were similar in ADF, ME and CP. Type of diet and liveweight at early weaning interactions were evaluated in a pen feeding trial for 62 days (Period 1).
