Choice feeding of the male and female broiler

1. Male and female broilers from 21 d of age were fed on either a complete diet or given a choice of whole wheat and one of two higher-protein foods formulated by omitting some or all of the cereal from the complete diet. 2. For males receiving the choice treatments, on average 44–7 and 73 73.1% by weight, respectively of the food consumed from 21 d consisted of whole wheat. The corresponding figures for the females were 49.9 and 77-3% respectively. 3. Growth rate from 21 d was significantly lower for the males which received wheat and the cereal-free higher-protein food and for the females on either choice treatment. Differences in the treatment means, however, were small.
