Alternative sources of protein in lamb diet

Abstract

The high price of protein nutrients as well as import orientation have triggered the demand for alternative protein sources in the feeding of lambs. In addition, it is necessary to take into account the degree of degradability of proteins. In order to ensure optimal amino acid pool for high genetic capacity of lamb growth, it is important to provide a protein fraction that avoids degradation in the rumen. An excellent source of protein that slowly degrades in the rumen is fish meal. However, given the recommendation of its non-use, the effects of the use of Eko fish meal, as a fishmeal substitute in diet of lambs of average body weight of about 14 kg and age of 30 days, were examined. The source of protein did not significantly affect the growth rate and the efficiency of food utilization in the lambs of MIS population in fattening (P>0.05), suggesting that fish meal can be successfully replaced by Eco Fish Meal. As an alternative to soybeans, in diet for lambs in fattening, the following were used: sunflower meal with the addition of fibrolithic enzyme, lupine, fodder peas, fodder beans were used, while in the more exotic areas the following were used: castor cake, pomegranate peel, product obtained after rice fermentation without any harmful effect on the biological efficiency of growth and food conversion.
