Abstract

This experiment was carried out to study the effect of feeding cottonseed meal
or linseed meal with three level of concentrate feed mixture (CFM): 2, 2.5, and 3% of
live body weight on animal performance and carcass quality. Sixty growing Australian
calves were randomly divided into 6 equal groups. All groups were fed on rice straw
ad lib as the sole source of roughage. Digestibility trials were conducted with three
calves chosen randomly from each group. Five calves of each group were slaughtered at the end of the experiment for carcass evaluation. Results indicated that the digestibility coefficients of all nutrients, feeding value of rations, average daily gain and dressing percentage of fasting body weight values increased with increasing level of CFM in rations. In additions, apparent utilization of rations was insignificantly different between the two types of CFM. It is concluded that the Australian calves can play a significant role in meat production in Egypt. Unseed meal can substitute cotton seed meal in traartional concentrate feed mixtures so that the cost of nutrition might be reduced. The recommended level of the CFM containing linseed meal woufd be 2% of SW.
