| Popis: | Ensiled grass is presently the major source of winter feed for dairy cows and other livestock in the UK. However, the quality and quantity of protein in grass silage tends to limit its use for milk production, which means that bought-in concentrate supplements must be fed to maintain high production levels. Whilst forage legumes such as red clover and lucerne appear to have potential as home-grown, protein-rich feeds for livestock (Frame et al., 1998), there is very little information available regarding their nutritive value when ensiled. The aim of this study was to compare the N balance of lambs offered red clover and lucerne silages harvested at two different growth stages. |
