Abstract
A commercially prepared alfalfa protein concentrate (APC), containing about 36% crude protein, was evaluated as a protein source for swine. In two experiments with growing-finishing pigs, no adverse effects on growth rate were observed with any level of APC used. At a dietary level of 24%, APC provided all the supplementary protein to a barley based diet; the growth rate was 1 kg per day. With creep and starter diets, the growth of pigs fed APC was inferior to the controls receiving soybean meal. With levels of 0, 14, 28 and 34% APC in starter diets, all levels of APC reduced growth (P < .05) in one replicate but did not in the other replicate. The results of these experiments indicate that APC has potential as a new protein supplement for swine. Copyright © 1975. American Society of Animal Science .
