An experiment was conducted for evaluation the effects of raisin waste (RW) on the performance, blood parameters and volatile fatty acids (VFA). Numbers of 15 Baluchi male lambs (average weight of 21.15±0.67 kg) were allocated to 3 treatments with a completely randomized design. Experimental treatments included: 1) control (40% alfalfa and no RW), 2) replacement of 50% alfalfa with RW and 3) replacement of 100% alfalfa with RW. Using RW in treatments 2 and 3 had a significant effect on average daily gain compared with control ration (P<0.05). With increasing the amount of RW in the ration, the total protein of serum (TPP) decreased significantly (P<0.05) in the first period of experiment (14-28 days). However, other blood parameters such as glucose, cholesterol, alanine aminotransferase (AST), triglycerides (TG), and blood urea nitrogen (BUN) were not affected by the treatments (P>0.05). The level of TG, AST, TPP and BUN decreased compared with control ration (P<0.05) within the second period of experiment (42-56 days). The lowest amount of acetic acid and valeric acid within the first period of the experiment was for treatment 3, while the highest level of valeric acid and isovaleric acid within the second period was for treatment 1( P<0.05). Adding RW to the ration had no significant effect on pH of ruminal fluid (P>0.05). Overall results showed that replacing part of alfalfa with RW as a low cost product not only had no negative-impact on the studied parameters in Baluchi lambs but it also improved their performance.

This experiment was conducted to study the effect of different levels of pure saponin (Loba Chemie Ltd.) on digestibility, fermentation parameters, ruminal protozoa population and blood metabolites in Baluchi male sheep. Four rumen fistulated Baluchi male sheep (LW=40.3±2.2kg) were used in a change-over design. Experimental treatments were 1) basal diet (control), 2) basal diet + 75 mg saponin per kg of diet (DM basis), 3) basal diet + 150 mg saponin, and 4) basal diet + 300 mg saponin. Saponin did not affect apparent digestibility of dry matter, organic matter, crude protein, crude fat, NDF, and ADF of the diet (P>0.05). Concentration of acetate, propionate, butyrate, valerate and also pH of the rumen fluid were not affected by the treatments (P>0.05), but the level of 300 mg saponin increased total volatile fatty acids compared to the control group (P<0.05). The mean of ammonia nitrogen concentration and total number of protozoa were decreased with the increasing of saponin in the diet (P<0.05). Also by increasing saponin in the diet, the mean of blood triglyceride concentration decreased (P<0.05) but cholesterol, HDL, and LDL level were not affected by the treatments (P>0.05). Although use of saponin up to 300 mg in the diet, had no negative effect on the health of animal, but among the studied parameters, ammonia nitrogen concentration, total volatile fatty acids, blood triglyceride and numbers of ruminal protozoa were affected by saponin. However, more studies are needed to prove the beneficial effects of saponins on animal performance.

This experiment was carried out to study the effect of oxidized soybean oil (OSO) against antioxidative ability of Pomegranate seeds (PS) on body antioxidant status and oxidative stress complications in periparturient Saanen goats. Blood total antioxidant capacity (TAC), Malondialdehyde (MDA) concentration, C-reactive protein (CRP), rheumatoid factor (RF) & enzyme activities were investigated three weeks pre and post-partum, through a completely randomized design with repeated measurements. Dietary treatments (T) included base diet and 4% fresh soybean oil (FSO) (T1), 4% OSO (T2), 4% OSO and 8% milled PS (T3)(DM basis). Three days after parturition similar diet was fed to all groups, to evaluation of durability of treatment effect. The blood enzyme activities of alkaline phosphatase (ALP), creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT) & lactate dehydrogenase (LDH), CRP, RF, MDA and TAC had ascending pattern in T2 vs. T1 and descending trend in T3 vs. T2. The ascending pattern in CRP, ALT, MDA and ALP and the descending trend in RF, TAS, CRP and ALP were significant statistically. Also two weeks after feeding similar diet, all parameters except CK, RF, TAC & MDA changed likewise previous pattern. Generally, the possible roles of lipid peroxidation derivatives of OSO led to progressive oxidative stress complications and reduced Blood TAC vs. FSO. Nevertheless, PS antioxidative components had beneficial effects on blood TAC and lowering role on oxidative stress signs.
