Physical form of feed - Pelleting feeds usually results in increased density and intake of the ration, and also improves growth and feed efficiency. Shown in Table 4 are results of three experiments comparing performance of broiler chickens fed pelleted and ground rations. These particular experiments were conducted on the same breed of chickens under similar management conditions. The differences in feed conversion observed within the pelleting treatment could have been linked with differences in pellet quality. It has been estimated that 0.01 in feed conversion is lost with each 10% increase in ‘fines’ in pelleted feeds. Although pellet quality may appear adequate immediately after leaving the feed mill, pellet quality at the time the flock is consuming the feed in the house is what counts. Every effort should, therefore, be directed toward improving the quality of pellets that arrive in the feed troughs for broilers.
