Evaluation of lathyrus (Lathyrus sativus L.) as an ingredient in pig starter and grower diets

Seed from Lathyrus sativus L., with a low content of β-N-oxalyl-L-α, β-diamino-propionic acid (ODAP), was evaluated as an ingredient (LM) in swine diets. The first experiment involved 45 pigs fed LM, containing 27% protein (CP) and 3 g ODAP kg −1 , as 0, 10, 20, 30 and 40% of starter diets (20% CP) over a 6-wk period. In exp. 2, two types of LM (0.9 and 2.7 g ODAP kg −1 ) were each included as 0, 10, 20 and 30 of mash diets fed to 84 pigs from 25 to 100 kg liveweight. The effects of pelleting and supplementation with 1 and 2 g methionine kg −1 , for LM diets containing 0.10). In exp. 2, ADG declined as the dietary content of either LM increased. The lower-ODAP LM-fed pigs had relatively higher ADFI (P
