Effect of sainfoin and forage:concentrate ratio on nitrogen balance, biohydrogenation and milk fatty acid profile in dairy ewes

This experiment was carried out the aim of the effect of sainfoin forage and forage:concentrate ratios on feed intake, nitrogen balance,ruminal biohydrogenation and milk fatty acid profile in dairy ewes using of eight Lori breed ewes according to a replicated 4 × 4 Latin square design. Treatments were adjusted from one to four according to forage:concentrate ratios of 35:65 with and without sainfoin and 65:35 with and without sainfoin. Dry matter intake was not significant among experimental diets. Retention of N was higher in ewes that receiveddiets consist of forage:concentrate ratios of 35:65 with sainfoin and 65:35 with and without sainfoin (P
