0.05). The concentration of colostrum minerals (arsenic, cadmium, cobalt, copper, iron, lead, magnesium, manganese, molybdenum, sodium, nickel, phosphorus, selenium, tin, zinc and calcium) was also not affected (P>0.05). So far, no studies have been performed on the addition of probiotics protexin to colostrum factors and minerals. However, there have been studies of the addition of probiotics to concentrations of albumin, total protein, and globulin and blood minerals. Contradictory results have also been reported in this case. The addition of protexin probiotics at the end of pregnancy on milk factors (fat, lactose, protein, solids and freezing point) in ewes was not significant (P >0.05). Consistent with our study, commercial bacterial probiotic feeding in ewes had no significant effect on the production and chemical composition of ewes. In other species of ruminants, the addition of bacterial probiotics and yeast probiotic resulted in inconsistent results on milk composition. The results were inconsistent due to differences in the amount and type of probiotic used, probiotic feeding method, type of ruminant, duration of probiotic use, and conditions of the ruminant (lactation).Conclusion Overall, the results showed that the addition of probiotics in the last month of pregnancy had no significant effect on body weight, colostrum factors, colostrum mineral content and milk composition of Lori Bakhtiari ewes. This indicates that the rations were normal and had no negative effect of probiotics in the last month of gestation on ewes. ]]>

0.05). The amount of BUN, creatinine, LDL and triglyceride significantly decreased by oak kernel treatments, but amount of blood cholesterol and HDL in treatments containing 10% increased (P<0.05). Protozoa population, rumen ammonia nitrogen and pH in diets containing palm kernel decreased as compared with that of the control diet (P<0.05).The potential and rate of gas production, microbial biomass efficiency and organic matter digestibility of soybean meal with rumen fluid animals fed with experimental diets for control treatment, and PF and microbial biomass for 10% palm date kernel significantly increased (P<0.05). Also the potential and rate of gas production of wheat straw with rumen fluid animals fed with experimental diets, microbial biomass and organic matter digestibility for control treatment, and PF and microbial biomass efficiency for 10% palm kernel significantly increased (P<0.05). There were significant amounts of lignin and resistant starch in the seed, phenolic compounds, volatile compounds and unsaturated fatty acids, flavonoids, carotenoids, and other compounds in the palm kernel that can influence parameters of current study.Conclusion According to the results of current study, due to the lack of negative effect on rumen fermentation and blood parameters and improving of performance, palm kernel can be used up to 10% in the Arabi sheep diet. Therefore, the use of palm kernels with the effect on the improving of livestock performance and high source of fiber, energy and fatty acids is an acceptable alternative to sheep diets.]]>
