In the first experiment, the nitrogen corrected apparent metabolizable energy (AMEn) and nutrients apparent digestibility of full fat soybean (FFSB) extruded at 145, 155 (common temperature) and 165 o C were evaluated. The corn-soy based diets were replaced with zero, 7.5, 15 and 22.5 % of each FFSB extruded at three temperatures during 15-21 d of age and AMEn and nutrients digestibility of EFFSB were calculated by regression analysis through extrapolation to 100 ٪ substitution in basal diet. The AMEn values of the FFSB samples extruded at 145, 155 and 165 o C obtained 3893, 3908 and 4037 kcal/kg, respectively and were not significantly different (P>0.05). The apparent digestibility of dry matter and ether extract in FFSB samples extruded at 165 o C, was higher as compared to FFSB extruded at 145 o C. In the second experiment, the effects of 15 % FFSB extruded at three temperatures, evaluated on performance, ileal digesta viscosity and morphology of jejunum mucosa of broiler chickens. Weight gain, feed intake and feed conversion ratio of 42 d chickens and ileal digesta viscosity of 21 d chickens were not affected by extrusion temperatures of FFSB. The jejunal villi lentgh of chickens increased with increase in extrusion temperature of FFSB, which resulted in significant increase (P

The replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of Holstein heifers have been evaluated. Fifteen Holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% wheat straw and 3) 36% treated wheat straw and 5 replicates for 2 months. Straw presses treated with 4% ammonia gas for 30 days. The results showed that the difference in dry matter intake and average daily weight gain and wither sheight among treatments is not significant. Digestibility of DM, CP, ADF and NDF in treatment 1 was significantly higher than other treatments. Ruminal pH and ammonia nitrogen in treatment 3 as were significantly higher than other treatments. Eating time, rumination time and total chewing time in treatment 3 was significantly higher than the other two treatments. Blood urea nitrogen in treatment 3 than the other two treatments and blood albumin in treatment2 were significantly higher than the other two treatments. Glucose, cholesterol, TG and AST and ALT had no significant difference among treatments. In general, for every kilogram of weight gain, in treatment 3 and treatment 2 as compared to treatment 1, 3860 and 3935 Rials were saved respectively The results showed that the treated straw with 4% ammonia gas can be completely replaced corn silage in the diet of Holstein heifers without negative impact on their performance.

Four-handed fifty lactating Holstein cows with mean body weight of, 597± 40 and 50±20 and days in milk body Condi from sure of 3.1±0.4 were blocked by parity and randomly assigned to 3 treatments. Each treatment had 3 pens and each pen had 50 cows. The experiment lasted for 60 days (10 days adaptation and 50 days collection period). Concentrate to forage ratio was 60 to 40 and alfalfa hay replaced with alfalfa silage. Dry mater intake, milk yield and composition did not changed significantly due to complete replacement of alfalfa hay with alfalfa silage. Milk urea nitrogen increased significantly (15.85 vs 14.69 mg/dl) when alfalfa silage was replaced with alfalfa hay. Rumen pH were similar in all treatments and higher than 6.0 of alfalfa silage diet. The result of this experiment indicated that in TMR based ration alfalfa hay can replaced completely with the alfalfa silage.

An experiment was conducted to predict the true metabolizable energy (TMEn) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of Sibbald in male boilers. In the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. Results of chemical composition showed that average values of dry matter, crude protein, ether extract, crude ash, crude fiber, calcium and phosphorus were 90.47, 20.99, 2.79, 2.88, 6.69, 1.08 and 0.49 percent, respectively with coefficient of variation between 2.01 to 13.29 percent. The average value of TMEn in compounded starter feeds was also obtained 3006 Kcal/kg with variation from 2884 to 3275 Kcal/kg and differences between them were significant. The variation between metabolizability values in the compounded feeds was 0.7 to 0.8 percent and differences between their values were not significant. The average value of dry matter true metabolizability in starter feeds was obtained as 54 percent and those having higher crude fiber, showed lower dry matter true metabolizability. The TME and TMEn values of compounded starter feeds showed a negative correlation as 0.38 and 0.59 percent with crude ash of feeds, so that the feeds containing higher crude ash had lower TME and TMEn values. Regression analysis showed that we can predict the TMEn value of broiler compounded starter feeds via regression equations from crude ash, crude protein, calcium and phosphorus contents of feeds from their crude ash, crude protein, calcium and phosphorus with R2 value as 0.67 (P=0.002).

This research was conducted to compare effects of electron beam (EB) and gamma ray (GR) treatments at doses of 25, 50 and 75 kGy on soybean meal (SBM) ruminal degradation kinetics of crude protein (CP) and amino acids (AA). The nylon bag and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) techniques were used for this aim. Ionizing radiations decreased washout and degradation rate fractions and increased potentially degradable fraction of CP. GR had more effects on degradability parameters of CP than the EB. Irradiation processing caused decreasing in AA degradation after 16 h of ruminal incubation significantly. GR irradiation was more effective than EB irradiation in lessening the ruminal degradability of AA. In unirradiated SBM, subunits ά, α and β of β-conglycinin protein disappeared after 4 h, and basic and acidic subunits of glycinin protein disappeared after 16 h of rumen incubation. The 50 and 75 kGy doses of EB and GR maintained and preserved the subunits of β-conglycinin until 16 h and 48 h for glycinin subunits. The results of this study showed greater effects of GR than the EB in reducing the ruminal degradation of CP and AA, while the ruminal disappearance of the protein subunits in the SBM was equally affected by these ionizing radiations.

The objective of the present study was to investigate the effects of dietary L-arginine on performance, meat production and its chemical composition, carcass fat deposition, intestine morphology and blood parameters of Ross broiler chickens during 46 days. In this experiment, 192 day old commercial female Ross broiler chicks were used with 4 dietary treatments and 4 replications in a completely randomized design. Dietary treatments included 100, 153, 168 and 183 percentages of digestible arginine, based on the Ross catalogue recommendation. On 46th day of experiment, three chickens per replication were selected randomly, blood samples were collected from each, and thereafter they were slaughtered in order to measure carcass traits, intestine morphology and meat chemical composition. The results showed that dietary arginine treatments caused a significant increase on body weight, carcass efficiency, muscle yield, protein and fat content of muscle, heart weight, and growth of small intestine, while decreased abdominal fat weight. Arginine supplementation increased plasma concentrations of triiodothyronine and thyroxine, but reduced plasma concentrations of cholesterol, triglyceride, and urea. According to the results of this study, consumption level of 168% digestible arginine, based on the Ross catalogue recommendation, had the best results on growth improvement and carcass traits, while consumption level of 183% digestible arginine had the greatest fat carcass reduction.

In order to investigate the effect of different levels of zinc on some productive parameters of broiler breeder, an experiment was conducted with 300 hens and 40 roosters of Ross 308 strain (40 wk old) in 12 week period in completely randomized design with 4 treatments, 5 replicates and 15 hens and 2 roosters in each replicate. Treatments consisted of 4 different levels of zinc (80, 110, 140 and 170 mg zinc/kg diet) in which the dietary zinc was supplied from zinc sulfate. Zinc supplementation significantly improved egg production, egg weight, egg shell quality and feed conversion ratio during the experiment. Production percentage and feed conversion ratio had the best results in 170 mg zinc/kg diet and the best results of egg weight and egg shell quality were observed in 140 and 170 mg zinc/kg diet. Zinc supplementation improved the weight and quality of neonatal chicks. By increasing levels of zinc in the diet, weight of bursa fabricius of chicks and weight of heart of broiler breeders increased. The results of this experiment suggest that supplementation of broiler breeder diet with zinc could improve performance and quality of neonatal chicks.

This study aimed to investigate the effect of different levels of silymarin against lead induced oxidative stress in broiler chickens. Therefore, 240 broiler chickens of Ross 308 allocated to 24 experimental units in a completely randomized design with factorial 2x3 arrangements and four replicates of 10 birds. The experimental diets containing silymarin at 3 levels (0, 100, 200 mg/kg) and 2 levels of lead (0, 200 mg/kg) were fed for 6 weeks. Results of this experiment showed that supplementation of 200 mg/kg silymarin attenuated adverse effect of lead on body weight gain (BWG) and feed conversion ratio (FCR) in 42 d. Also, addition of 200 mg/kg silymarin in lead-induced oxidative stress improved carcass characteristics. In addition, supplementation of silymarin in lead-induced oxidative stress no significantly decreased blood lipid parameters (cholesterol, triglyceride, LDL). Furthermore, supplementation of 200 mg/kg silymarin significantly increased superoxide dismutase (SOD) and decreased malondealdehyde (MDA) and heterophyle /lymphocyte (H/L ratio). These results suggested that supplementation of silymarin in lead induced oxidative stress had a protective role and by improving the antioxidant system improved the performance.

This study was carried out to investigate the effects of 1, 25-Dihydroxycholecalciferol (1, 25 (OH)2 D3) and
root hydroalcoholic extract of Withania somnifera (WS) root on performance, mineral retention, bone
mineralisation and mechanical characteristics of broiler chicks. Treatments were arranged factorially (2×3×2)
consisted of a positive control with adequate Ca and a negative control diet (Ca level reduced by 30%), three
levels of WS (0, 75 and 150 mg/kg diet), and two levels of 1, 25 (OH)2 D3 (0 and 0.5 g/kg diet). Six hundred
male day old Ross 308 broiler chicks were randomly distributed into 60 floor pens, 10 birds each. Each treatment
was replicated 5 times (50 birds). Each diet was fed ad libitum to chicks from day one to 42 d of age. On d 21
and 42, one bird per replicate was killed and left tibia removed. Dietary treatments did not influence feed intake
and feed conversion efficiency. The maximum body weight gain (2475.75 g) was noted in group fed adequate
dietary Ca supplemented with 75 mg/kg WS. The retention of Ca and P were significantly higher at lower level
of dietary Ca. Supplementation of 150 mg/kg WS significantly improved dietary Ca retention in birds received a
negative control (83.09%) compared to those consumed positive control diet (66.35%). Regardless of dietary Ca
level, in birds fed 75 mg/kg WS, addition of 0.5 g/kg 1, 25 (OH)2 D3 significantly improved Ca retention. On d
21, Birds received WS had significantly higher tibia Ca compared to those of control group. Whereas, no
significant effects was noted at 42 d. Birds fed on negative control diet supplemented with 75 mg/kg WS and 0.5
g/kg 1, 25 (OH)2 D3 displayed similar tibia Ca compared to those fed only 150 mg/kg WS. Supplementation of
1, 25 (OH)2 D3 in diet significantly increased tibia Ca at 42 d of age. Tibia shear force and stiffness significantly
increased by supplementation of Withania somnifera. The present study indicated that Withania somnifera
supplementation exerts positive effects on Ca retention, bone calcification and mechanical properties without
adverse effects on performance. Also, synergistic effects of withania Somnifera and 1, 25 (OH)2 D3 was
observed on Ca retention and bone calcification.
