Use of sweet lupin (Lupinusalbus L. var. Multitalia) in feeding for Podolian young bulls and influence on productive performances and meat quality traits.
The objective of this study was to evaluate the effect of sweet lupin (Lupinusalbus L. var. Multitalia) as a substitute for soybean (Glicinemax [L] Merr.) in feed on the productive performance and meat quality of Podolian young bulls. The steers were divided into 2 homogeneous groups and were fed durum wheat (Triticumdurum L.), straw and a complete pellet feed containing 20% sweet lupin seeds or 16.5% soybean. Productive performances were similar for both groups. The values of pH, measured on Longissimuslumborum and Semitendinosus muscles 24h after slaughter, were similar. No differences were shown between groups regarding the colour characteristics of both muscles or the tenderness of the cooked meat. No statistical differences were found between diets regarding the fatty acid profile of meats, except for a significantly higher incidence of linoleic acid in the meat obtained from animals on soybean feed. In conclusion, comparable results were obtained when soybean was replaced with sweet lupin seeds in complete pellet feed for Podolian steers.
