Average daily gains and profitability of calf- rearing during pre-weaning period

This research was done to determine pre-weaning average daily gains and nutrition cost calves fed with milk replacer (R1), milk (R2) and combination of milk and milk replacer (R3) with ad libitum consumption of pre-weaning total mixed ration (TMR). Calves fed with R2 had significantly (p<0.0001) higher average daily gains then calves fed with R1 or R3. Feeding calves with R3 resulted in the lowest costs of pre-weaning nutrition. Considering average daily gains and total costs of preweaning nutrition, the most profitable pre-weaning nutrition model was the one including milk and TRM.
