CHEAPER PROTEIN FEED FOR PIGS
[Vol. XXVI, Part IV,
SUMMARY
Two studies one in summer and the other in winter, each of 6 months duration
with weaned piglings were undertaken to investigate whether groundnut cake
with high protein content can be used more effectively in place of maize in pig rations.
In summer study piglings getting 12 per cent digestible protein ration containing
10 per cent groundnut cake gave significant gain in weight over piglings getting
27 per cent digestible protein ration containing 50 per cent groundnut cake. However,
in winter study it was the group of piglings getting higher digestible protein
ration (27 per cent) containing 50 per cent groundnut cake which gave significant
weight difference over the group getting lower digestible protein ration (16 per cent)
containing 20 per cent groundnut cake.
In the summer study the group of piglings getting higher groundnut cake
content ration gave a net return of Rs. 64.0 for every 100 rupees of feed consumed,
while the corresponding group on high maize content ration gave a net return of
only Rs. 37.7, a reduction of Rs. 26.8 per 100 rupees of feed cost. In the winter
study the higher groundnut-cake-fed group gave a net return of Rs. 50 per 100
rupees of feed cost. While the corresponding figure for the other group was 28.6,
a difference of Rs. 21.4 per 100 rupees of feed cost.
