pFATS AND PELLETS IN BROILER RATIONS

It is estimated that over three-fourths of the commercial rations currently fed to broilers in this area are in crumbles or pellet form. Bearse and coworkers (1952), Lanson (1954), and Lanson and Smyth (1955) have shown that pelleting improved growth and feed conversion of broilers fed high-efficiency rations. Little experimental information is presently available regarding the value of pelleting broiler feeds containing animal fat. Procedure The experimental plan involved four groups of sexed, day-old broiler fed mash or pellets each in the presence or absence of 3 % animal fat 2/. This procedure was repeated at three different intervals with 200 New Hampshire chicks of mixed sex used in each of the first two experiments (1 and 2) and 192 Delaware chicks of mixed sex in the third experiment (3). Experiment 1 was of 8 weeks t duration while experiments 2 and 3 were of 9 weeks ' length
