Abstract
Two experiments were conducted to assess the addition of pistachio by-product biochar (PBB) to lactatingIn first experiment, the effects of the addition of different levels (0, 0.5, 1 and 1.5% diet on dry matter basis, DM) ofPBB on rumen fermentation parameters after 24h of incubation were investigated ...

Two experiments were conducted to assess the addition of pistachio by-product biochar (PBB) to lactatingIn first experiment, the effects of the addition of different levels (0, 0.5, 1 and 1.5% diet on dry matter basis, DM) ofPBB on rumen fermentation parameters after 24h of incubation were investigated in a completely randomized designwith four treatments and three replications. Second experiment was designed to evaluate effect of feeding selectedlevel of PBB on performance and nutrient digestibility of 8 lactating Kermanian ewes in a Latin square change-overdesign with two 21-day periods. Methane production and ammonia-N concentrations decreased linearly (P<0.01), andpH increased linearly (P<0.01) as the dietary level of PBB raised. With the addition of 1%diet, milk yield, blood glucose, digestibility of DM increased (P<0.05) and blood urea nitrogen (BUN) decreased(P<0.05) compared to control group. In general, adding 1% of PBB to lactatingand digestibility of DM.

This experiment was conducted to evaluate the effect of silver nanoparticles coated on clinoptilolite on performance traits, liver enzymes and blood lipid concentrations to use 375 Cobb 500 broiler chickens in completely randomized design with five treatments and five replicates and 15 birds to each replicate. The use of silver nanoparticles coated on clinoptilolite improved feed conversion ratio compared with the control treatment (P<0.05). Dietary treatments had no significant effect on the feed intakes and weight gain (P>0.05). The use of silver nanoparticles coated on clinoptilolite decreased alkaline phosphatase and alanine amino transferase level in serum (P<0.05). Silver nanoparticles coated on clinoptilolite be can decreased cholesterol, triglycerides, low density lipoprotein, very low density lipoprotein concentration and increased high density lipoprotein concentration in broiler chickens (P>0.05). In conclusion, the results of this study showed that silver nanoparticles coated on clinoptilolite can be considered as a growth and health promoters as well as according to the results of liver function enzymes and blood lipids prevent liver damages during rearing period in broiler chickens.
