Effect of flaxseed and cannula seed on digestibility and some of blood parameters in Kurdish ewes durring Postpartum period

Dietary fat has been shown to improve reproductive performance and lactation. Therefore, this experiment was conducted to investigate the effects of adding cotton and canola to Kurdish ewes' diet on the ability to digest the nutrients, some metabolites and blood hormones were carried out after birth.

The design was carried out in a completely random design. Treatments included 1) diet without oilseed 2) diet containing 6% cotton dry matter 3) diet containing 6% cotton dry matter 4) diet containing 3% f cotton and 3% cotton dry matter. Feed digestibility was calculated according to the method of Wankulen and Young (1977). Blood samples were taken at 5, 3 and 1 weeks after calving to assess blood metabolites and hormones. rumen fluid was obtained by oral sucker.

The results showed that the effect of treatments on ruminal pH was significant at 5% level, with the highest pH related to canola seed treatment (6.60). Blood glucose levels were significantly increased in all treatments (1, 3 and 5 weeks) in treatments containing oilseed (P <0.01). The highest amount of glucose was related to canola seed treatment in the 5 week of calving (90.90 mg / dl). Blood cholesterol levels in all three treatments were significantly increased in treatments containing oilseed, and the highest cholesterol level was observed in the cotton and canola (85 mg/dl) treatment one week after calving (P <0.01). Insulin levels were significantly increased in canola treatment at week 3 and 5 (P <0.01). Among the digestibility factors, dry matter increased in treatments containing oilseed, and the highest dry matter was in cotton and canola (54.42) (P <0.05). NDF was significantly decreased in treatments containing oilseed and the lowest NDF was in canola seed treatment (45.52) (P <0.05).

The overall results of this study showed that the use of oilseeds improved digestibility and it has had a positive effect on blood cells. Therefore, it is recommended to use a diet containing 3% dry matter cotton and 3% canola dry matter in postpartum period.
