[Effect of amino acid supplements to barley meal on the nitrogen metabolism of growing castrated male swine (20-65 kg live weight)]. 1981

C Wecke, and G Gebhardt

In 56 N-balance experiments of the influence of differentiated amino acid supplements to coarse barley meal enriched with energy, minerals and additives on the nitrogen metabolism of castrated male pigs, was investigated. The joint supplement of lysine and methionine remained without result in comparison with the sole supplementation of lysine. Only the additional supplementation of threonine resulted in the further improvement of protein utilisation. The results corroborate the effect of the amino acid lysine limiting the performance in barley protein and prove that threonine takes the second place in the sequence of limitation.
