SUBSTITUTION OF THE PROTEIN-SOURCES BY HOME-MADE PROTEIN MOLASSES IN RATIONS FOR GROWING PIGS

A total of 72 pigs of 15 kg liveweight were used in a random block des ign for studying their performance on substituting 0, 60 and 80% of th e protein sources by home made protein molasses (HPM). The HPM was pre pared with 2% urea and a 30:70 molasses B:water proportion. Average da ily gain was reduced and had values of 475, 301 and 277 g for 0, 60 an d 80% substitution. Other performance indices were poorer in the anima ls which consumed HPM, but these required lower amounts of protein sou rces. The evaluation of lower than 60% substitution levels is suggeste d.
