In this experiment, the effect of oak kernel on digestibility, rumen fermentation and some blood parameters of Arabi sheep and Najdi goat were investigated. In this research, oak kernel (63%) was used for feeding six Arabi sheep and six Najd goats with the mean live weight of 50 ± 3 Kg for 28 days, and digestibility and fermentation, rumination and some blood parameters were measured. Obtained data were analyzed in split plots design. The results showed that dry matter intake and digestibility of dry matter, crude protein and neutral detergent fiber were not affected by treatment and type of livestock. Regardless of the type of livestock, dry matter intake and crude protein digestibility in control treatment was significantly higher and regardless of the type of treatment, the digestibility of dry matter and neutral detergent fibre of goat was higher than sheep (P<0.05). The ammonia nitrogen and pH of rumen between control and oak treatments for goats and sheep was almost the same. Time to eating, rumination and chewing for dry matter, NDF and crude protein between control and oak diets in sheep and goats was not different. Feeding the livestock with oak had no significant effect on the amount of blood glucose, urea nitrogen, cholesterol and triglycerides in sheep and goats. The results of this experiment showed that 63% oak fruit could be used in diet of Najd goat and Arabi sheep.

This experiment was conducted to investigate the digestibility and fermentation parameters of diets containing flower, pod with seed and leaf of siris in sheep by two-step digestion and gas production methods. The experimental diets were including zero, 25, 50, 75 and 100 percent of Siris flower, pod and leaf. The result showed that gas production potential of diet containing 50 percent leaf was greater than other treatments (P<0.05). Gas production rate of diet containing 75 percent flower showed significant increase compared with the other diets (P<0.05). Partitioning factor, microbial biomass, biomass efficiency were the greatest for diets containing 100 percent leaf and different levels of pod (P<0.05). Dry matter digestibility of diets including different levels of siris leaf, 50 percent siris flower and 25 percent siris pod and neutral detergent fiber digestibility of diets including different levels of siris flower and 25 percent Siris pod were higher compared to control diet (P<0.05). The lowest concentration of ammonia nitrogen was belonged to diets containing 100 percent leaf and pod of Siris (P<0.05). It could be concluded that Siris leaf, flower and pod with seed of siris can be used instaed of alfalfa in sheep diet and increase digestibility and diet ruminal fermentation.
