In tropical and subtropical areas crop residues and agro-industrial by-products are used for feeding ruminant livestock under limited or zero grazing conditions. In order to increase feedding efficiency and livestock productivity supplementations are essential to meet deficient nutrients for diets. For the assessment of the impact by supplementation or supplements by various nitrogen sources together with salts and minerals upon energy utilisation C-14 labelled acetate was used for tracer to measure outflow rates of volatile fatty acids (VFAs) from rumen by Angora goat bucks. The supplemented diets led to increased VFAs outflow rates from rumen.
The conclusion was that ruminant diets consisted by crop residues and agroindustrial by-products need supplementations for deficient nutrients to increase efficiency of feed energy utilisation by ruminant livestock. The impact upon VFAs production by supplementation was assessed easily by nuclear technique.
