Abstract: 

This experiment was carried out to study the effects of sainfoin (Onobrychis viciifolia) as tannin source and different level of forage: concentrate ratio on digestibility, blood parameters, ruminal fermentation, milk yield and milk composition in milking ewes. Therefore, eight Lori milking ewes were alocated to factorial experiment base on the 4´4 replicated Latin square design. Four total mixed ration diets were formulated with two level of concentrate and two level of intake forage which consisted of forage: concentrate ratios of 35:65 high concentrate without sainfoin (HC), 65:35 low concentrate without sainfoin (LC), 35:65 high concentrate with sainfoin (HCS) and 65:35 low concentrate with sainfoin (LCS). Total phenols, total and condensed tannin among treatments were significantly different (P<0.05). Digestibility of DM and OM in the HCS treatment were higher compared to the other treatments (P<0.05). The ruminal pH and NH3-N values in HCS and HC diets were lower than those fed HC diet. The concentration of ruminal VFAs in ewes received low concentrate diet were higher (P<0.05). The acetate to propionate ratio was lower in HC and HCS treatments. The results showed milk yield in HC and HCS treatments was greater than other treatments (P<0.05). Level of concentrate effect were significant on milk fat, lactose, SNF and protein (P<0.05). In total, adding to sainfoin as a tannins source to diet with high concentrate ratio (65%) increased organic matter and fiber digestibility, and also increased ruminal propionate and finally, increased milk yield and protein.
