Nitrovin supplementation of diets for growing pigs

Abstract

Two experiments were conducted to examine whether the chemical nitrovin, a gudnidine derivative, would promote growth in pigs. In the first experiment, conducted at the Agricultural Research Station, Cressy, Tasmania, the addition of 20 p.p.m. nitrovin significantly increased liveweight gain by 5.5 per cent and feed conversion by 5.2 per cent. In the second experiment, conducted at the Agricultural Research Station, Wollongbar, N.S.W., the addition of 23 p.p.m. nitrovin significantly increased liveweight gain by 11.3 per cent but had no effect on lean in the ham. Feed conversion efficiency (not statistically analysed) was 10.6 per cent more efficient in pigs supplemented with nitrovin.
