In order to investigate the effect of using different levels of pistachio seed coat (PSC) on feed intake, ruminal parameters, microbial protein synthesis and nitrogen retention in Kermani sheep, four male sheep with a mean weight of 54 ± 2 kg were used. This experiment was conducted in 4×4 Latin square design in 4 periods of 21 days. After determining the chemical composition of PSC, it was used in the preparation of experimental diets and replaced with wheat bran. The experimental diets were: 1) control diet (without PSC), 2) diet containing 5 % PSC, 3) diet containing 10 % PSC and 4) diet containing 15 % PSC. The results showed that feed and nitrogen intake, excreted nitrogen and nitrogen retention were not affected by feeding the experimental diets. Adding PSC to the diet reduced ruminal ammonia nitrogen (P < 0.05), however, it did not affect the pH of ruminal fluid at 0, 2, 4, 6 and 8 hours after feeding. The total protozoa population of the rumen was not affected by experimental diets, while the population of cellulolytic species increased linearly (P < 0.05). There was no significant difference between the treatments in terms of total purine derivatives, allantoin, creatinine, uric acid, hypoxanthine, xanthine and, microbial protein synthesis. According to the results, PSC can be used up to 15% of dry matter in sheep diet and replaced with wheat bran or other diet ingredients.

The effects of replacement of alfalfa hay and wheat straw with different levels of tarragon plant stalk (TPS) on feed intake, digestibility, microbial protein synthesis, and blood and rumen parameters of sheep were investigated using four Kermani male sheep (BW= 45±2 kg) with approximately three years old in a Latin square design with four 21-day periods. The experimental diets were: 1) control diet (without TPS), 2) diet containing 8% TPS, 3) diet containing 16% TPS and 4) diet containing 24% TPS (DM basis). Dry matter intake, and dietary digestibility of DM, OM and CP were not affected by feeding of TPS in the present research. The amounts of nitrogen intake, nitrogen excreted in the urine and feces, the amount and percentage of retained nitrogen, ruminal pH, ruminal concentrations of NH3-N and volatile fatty acids, and protozoa population were not affected by experimental diets. Feeding different levels of TPS had no effect on, microbial protein synthesis, and concentrations of blood glucose, total protein, urea nitrogen, triglyceride and cholesterol. Results of this study showed that tarragon plant stalk could be replaced with alfalfa hay and wheat straw up to 24% (DM basis) in sheep diet without any effect on ruminal fermentation, blood parameters or feed intake.

The effect of feeding ensiled licorice pulp with different levels of wasted date was investigated on ruminal fermentation parameters, blood parameters and microbial protein synthesis on four male mature Raeini goats. The experiment was designed as a 4×4 Latin square design with four 21 days periods. Licorice pulp was mixed with 0, 5, 10 and 15 percent of wasted date without stone and ensiled in 40 L containers for 45 days. Experimental diets were: 1) control (20% ensiled Licorice pulp without wasted date, 2) 20% ensiled licorice pulp with 5% wasted date, 3) 20% ensiled licorice pulp with 10% wasted date and 4) 20% ensiled licorice pulp with 15% wasted date. The results showed that ensiling licorice pulp with different levels of wasted date significantly increased DM and fleig point linearly (p

Abstract
This study was conducted to evaluate the effect of adding waste dateand ensiling periods on chemical compositions and quality of ensiled lemon. For ensiling, different levels of waste date without stones (0, 10, 20, 30, percent) were mixed with lemon pulp and ensiled in two-liter ...

This study was conducted to evaluate the effect of adding waste dateand ensiling periods on chemical compositions and quality of ensiled lemon. For ensiling, different levels of waste date without stones (0, 10, 20, 30, percent) were mixed with lemon pulp and ensiled in two-liter containers for 25, 35 and 45 days. After opening the silages, samples were taken for determination of dry matter, crude protein, ammonia-nitrogen, neutral detergent fiber, organic matter and ash. The pH of silages was determined immediately after opening. The effects of waste date supplementation without stone was studied as a factorial design (3×4). The results of this study showed that silage of lemon pulp with 30percents waste date improved silage quality and increased DM, OM and pH (P<0.05). However, CP, NDF, NH3-N and ash were decreased (P<0.05). Also, lemon pulp silage with 30percent waste date had the highest energy and sensory evaluation than those of other silages. In conclusion, supplementation of 30per cent waste date without stone to the lemon pulp and the optimum ensiling period of 45 days are recommended.

The aim of this experiment was to study the effects of two levels of barley silage particle sizes and two levels of non-forage fiber on feed intake, nutrients digestibility, rumen parameters and feeding behaviors in sheep. Whole-plant barley was harvested at 28% moisture in 8 and 16 mm theoretical chop lengths to prepare short and long silages. Four male sheep with the weight of 46±7 kg were used and experimental diets were: 1) coarse barley silage diet without beet pulp, 2) coarse barley silage diet with 20% beet pulp, 3) fine barley silage diet without beet pulp and 4) fine barley silage diet with 20% percent beet pulp. The NDF intake was affected by beet pulp levels (P=0.05) and the highest NDF intake was in sheep fed with fine barley silage diet with 20% beet pulp (P<0.05). The DM, OM, CP, and NDF digestibility were affected by an interaction between barley silage particle sizes and beet pulp levels, and the highest digestibility of nutrients were in fine barley silage diet and 20% beet pulp (P<0.05). Two and four hours after feed intake, the lowest rumen pH was in animals fed fine barley silage diet and 20% beet pulp (P<0.05). The NDF consumption increased when barley grain was replaced with sugar beet pulp in diets containing high levels of concentrates and low levels of physical effective fiber.

The effect of feeding silage of leaf and stem of banana tree with waste date palm on feed intake, microbial protein synthesis and blood parameters using four adult rams in a change- over design with four 21-days period were examined. Eighty five kg leaf and stem of banana tree with 15 kg of waste date palm were mixed together and ensiled for 45 days. Chemical composition and sensory evaluation of silage of leaf and stem of banana tree with waste date palm was evaluated and used in experimental diets as zero, seven, 14 and 21 percent of DM. According to sensory evaluations, silage with a score of 20 had a very good rating. Nitrogen retention in sheep fed 21 percent silage was lower than the control group (P<0.05). Dry matter digestibility of experimental diets containing 14 and 21 percent silage was lower than diets containing zero and seven percent silage (P<0.05). The mean excretion of allantoin, uric acid and total purine derivatives in the urine of sheep were increased linearly (P<0.05) with increasing the silage in the experimental diets. Increasing of nitrogen and microbial protein synthesis in sheep fed diet containing 21 percent silage was more than sheep fed diet without silage (P<0.05). Increasing of the silage level in diet, was increased triglyceride concentration by linearly (P<0.05). According to the results, using of 21 percent silage of leaf and stem of banana tree with waste date palm in sheep diet without change in dry matter intake, increase microbial protein synthesis.
