In this study, records of 305-d and first lactation production traits of 13601 Holstein cows were used to estimate genetic parameters and genetic trends for production traits of Holstein cows resulted by imported semen. These data were collected from 218 herds during 1999 to 2013 by Animal Breeding Center of Iran. Procedure GLM software SAS, 9.1 was used for effect fixed (herd effect, semen type, year, month of calving) and age of calving as the covariate. Estimated were genetic and phenotypic variance (co) milk yield, fat and protein percentage traits by Wombat and univariate and bivariate animal model. Heritability of milk yield, fat and protein percentage were (0.23±0.007, 0.46±0.01 and 0.52±0.021) respectively. Genetic correlations between milk yield-fat percentage, milk-protein percentage and protein-fat percentage were (-0.30±0.021, -0.42±0.017 and 0.16±0.001) respectively. Compared the genetic trend milk, fat and protein percentage traits difference between daughters of semen American, Iranian and Canadian was significant (p<0.05). The most mean breeding value for milk, fat and protein percentage imported semen to American and Canadian and lowest mean breeding value were Iranian semen. Perform well have American semen to climate Fars province.

In order to genetic evaluate of milk yield in Iranian Holstein dairy cows a total of 276767 first lactation records from different provinces of Iran within 583 herds collected from 1991 to 2008 were used. The records were corrected for 305 days in milking, twice daily milking and mature equivalent age. The records less than 2500 and higher than 13000 kg were deleted before analyzing of data. To identify factors affecting milk yield a general linear model (GLM) procedure was applied and then herd-year-season and age at first calving were considered as fixed and covariate factors in the model respectively. A single trait animal model was applied for estimation of genetic parameters using restriction maximum likelihood (REML) method. Mean and heritability of milk yield were obtained 7944±1743 (kg) and 0.28±0.01 respectively. Genetic and phenotypic trends were 46.4±2.4 and 147.27±5.7 kg/y respectively (P<0.01). Classification of dairy cows based on their sire origin (Iranian, European, Canadian and American) showed that the maximum and minimum of breeding values belong to dairy cows by American and Iranian sire origin respectively (739 VS 256 kg). The maximum of phenotypic mean (9066 kg) and breeding value (577 kg) were observed for Qazvin province. The minimum of phenotypic mean was observed for Khuzestan province (5211 kg) and the minimum of breeding value was observed for Qom province (27 kg). The highest and lowest genetic trends of 50.7 and 18.2 kg/yr were obtained for Qazvin and Khuzestan provinces respectively. Moreover, the best age at first calving was determined 23 month for Iranian Holstein dairy cows.

Husbandry conditions including environmental and managmental factors, were the same for three strains during each experimental periods. The traits under consideration were daily body weight gain, daily feed intake, feed conversion ratio, means of live body weight, index of production, livability, carcass percentage, percent of breast, thigh and abdominal fat in end of 42th days of age. Statistical analysis of performance criteria showed that difference of daily weight gain in 42 days among of strain was significant and B had highest and C had lowest means of daily weight gain (P<0.05). Effect of nutrition program in this trait was significant and pellet form diets had highest and four phasing diets had lowest daily weight gain (P<0.05). Difference in means of daily feed intake in strains was very significant and B and C were highest and lowest respectively. Effect of nutrition program on daily feed intake was significant and pellet form diets was highest and four phasing diets was lowest in this trait (P<0.05). Analysis of average of live body weight show the significant difference among the strains and B had highest and C lowest amount in this trait (P<0.05). Effect of nutrition program on this trait was significant and diets with low protein and energy and pellet form diets were highest and diets with high energy and protein was lowest (P<0.05). There were no significant difference between strains and nutrition program in feed efficiency ratio. The effect of nutrition program on livability was significant and diets with high level of energy and protein was highest and four phasing diet was lowest in livability (P<0.05). Also Carcass percentage had significant difference among strains and B had highest and C had lowest in this trait (P<0.05). The effect of nutrition program on this trait was significant and diets with high energy and protein had highest and diets with low protein and energy had lowest means of carcass percentage (P<0.05). Strain had significant influence on breast percentage and B had highest and C had lowest of breast percentage, respectively. Significant effect of strain on thigh percentage was observed and C and B had highest and lowest percentage of thigh respectively. Strain had very significant effect on abdominal fat percentage and B had highest and A had lowest abdominal fat percentage (P<0.05). Calculated production index showed that effect of strain was significant and B had highest and C had lowest amount of this index (P<0.05). Effect of nutrition program on production index was significant and diets with high energy and high protein and pellet form diets had highest and four phasing diets and diets with low energy and low protein had lowest amounts of production index (P<0.05).

To determine the effects of different sources of oilseeds including n-3 and n-6 fatty acids (FA) on blood metabolites, sex ratio and reproductive parameters in Zel ewes' a total of 102 ewes were assigned randomly to three diets in a completely randomized design. Diets contained either basal diet (Control), n-3 (Canola), or n-6 (roasted whole soybeans), and they were fed for 56 d. Results showed that there were no significant differences among treatments in glucose, triglyceride and LDL concentrations, but cholesterol and HDL were significantly higher in ewes fed n-3 and n-6 fatty acids compared with those control diets. Lambing rate was significantly greater in ewes fed n-3 (82.3%) and n-6 (82.3%) compared with ewes fed control diets (70.2%) but there were no significant differences between ewes fed diets n-3 and n-6. Treatments affected sex ratio of offspring (P<0.05). The proportion of male offspring was significantly higher when ewes were fed the control diet (44.1 %) compared with n-3 (32.3 %) and n-6 (35.2 %) fatty acids diets. In conclusion, feeding a source of n-3 or n-6 fatty acids can be a strategy to increase oestrus behavior and lambing rate in ewes.

A study was conducted to evaluate the effects of three medicinal plants, antibiotic and probiotic on performance, carcass traits, immune system and biochemical parameters in broiler chicks. A total of 360 one-day old mixed Ross-308 broiler chicks were assigned to six treatment with 3 replicate (n=20). The diets were fed including: the control (without feed additive), control supplemented with 20 ppm of virginamycin, control supplemented with 50 ppm of probiotic (protexin), control with 1.5% of either Thyme (thymus vulgaris L), Chicory (cichorium intybus), Pennyroyal (mentha pulegium). Body weight gain increased with antibiotic supplementation and decreased with adding Pennyroyal (P<0/05) respectively, but the difference between chicory and control, antibiotic and probiotic was not significant. Feeding diets supplemented with antibiotic, probiotic, Chicory, and Thyme had no significant effect on feed intake, while the feed intake decreased by feeding Mentha pulegium (P<0/05). Dietary treatments had no effect on the feed conversion ratio, relative weight of abdominal fat, liver, and tight. However, carcass yield decreased by feeding diets supplemented by Pennyroyal (P<0/05). The level of glucose, triglyceride, hetrophile, lymphocyte and hetrophile/lymphocyte had not significantly affected by dietary treatments. It was concluded that supplementation of Chicory and Thyme had no positive effects compared to diets containing antibiotic and probiotic on performance and blood metabolites in broiler diets.

This experiment was conducted to study the effect of using diets containing fermented fish waste on growth performance and carcass characteristics of broiler chickens. A total of 240 male Cobb 500 broilers were allocated into 5 treatments with 4 replicates (12 chickens in each replicate) using a completely randomized design. Experimental treatments contained 0, 3, 6, 9 and 12% fermented fish waste replaced by soybean meal in diets. Results showed that 1-10 days weight gain in chickens fed diets containing 9 and 12 percentage of fermented fish waste was more than chickens fed control diet (P<0.05). At 11-22 days and 23-42 days, replacing different levels of fermented fish waste with soybean meal in broiler diets improved weight gain and feed conversion ratio compared to the control group (P<0.05). Feed intake was not affected by treatments in any of the different periods of rearing. Liver weight in control treatment was significantly lower treatments containing fermented fish waste (P<0.05). Therefore, replacing a part of soybean meal with fermented fish waste in the diet improved growth performance and carcass characteristics of broiler chickens.

This study was carried out to evaluate the effect of different levels of metabolizable energy (2750, 2900 and 3050 kcal/kg) and crude protein (13, 15 and 17%) in the diet on the performance and egg quality of native laying hens of Mazandaran province at the first stage of production. For this purpose, two hundreds seventy 24-week-old native hens were randomly assigned to a 3×3 factorial design experiment. Egg production and feed intake were affected by different levels of energy (P<0.05). Egg production and feed intake reduced as energy level of the diet was increased. However, different levels of energy had not significant effect on final body weight, egg weight, feed conversion ratio and hatchability (P>0.05). Moreover, different levels of crude protein had significant effect on egg production (P<0.05). Egg production of laying hens increased by 12.9% as increased dietary crude protein level from 13 to 17%. According to results of this study, the diet of containing 2900 kcal metabolizable energy per kg and 15% crude protein is recommended for feeding of native laying hens of Mazandaran province in the first stage of production.

This experiment was conducted for effect of feeding fermented rapeseed meal on reduction salmonella population in broiler chickens. A total of 240 Cobb 500 broilers in a completely randomized design were allocated to 6 treatments with 4 replicates of 10 chickens each. Experimental treatments were including negative control (not challenged by salmonella), positive control (challenged by salmonella) and treatments containing 50 and 100% raw or/and fermented rapeseed meal replaced by soybean meal in diet. All broilers were challenged by Salmonella typhimurium using oral gavage except negative control at the end of 3 day of rearing. Results showed that 7 and 14 days post challenge, the percentage of contamination in fermented rapeseed meal treatments were less than positive control and raw rapeseed meal treatments. Weight gain and feed conversion ratio in positive control and 50% fermented rapeseed meal treatment were significantly different with other challenged treatments (P<0.05). Therefore, According to the positive results of feeding fermented rapeseed meal on health and performance of broiler chickens challenged with salmonella, this processed protein source could be considered as a new strategy to control salmonella contamination.

For evaluation the effect of Heracleum Persicum on performance, immunity, antioxidant activity, estrogen and some blood parameters of broiler chickens, a total of 192 Ross 308 broilers were trained in a completely randomized design with 4 treatments, 4 replicates and 12 observations in each replicate. Treatments were included the levels of zero (control(, 0.3, 0.6 and 0.9% of Heracleum Persicum seed powder in diet. Heracleum seed levels caused the higher weight gain and feed intake in starter, grower and total rearing periods (P<0.05). The feed conversion ratio in starter period was not affected by treatments. In grower and total periods, the lowest feed conversion ratio was in 0.6% of seed (P<0.05). The Heracleum seed increased the primary and secondary antibody responses against SRBC (P<0.05); But, there was no significantly effect on bursa and spleen weights. The 0.6% of Heracleum caused the lower heterophil and higher lymphocyte percente. The heterophil/lymphocyte ratio in 0.3 and 0.6% of Heracleum was lower than control (P<0.05). The Heracleum increased the total antioxidant capacity of plasma (P<0.05). The Heracleum has no significantly effect on blood serum estrogen and glucose levels. The Heracleum seed levels caused the lower blood concentrations of triglycerid and LDL and higher HDL value (P<0.05). The 0.6 and 0.9% of Heracleum seed caused the lower blood colestrol level (P<0.05). Carcase characteristics were not affected by treatments. In conclusion, the Heracleum Persicum improved the performance, immune function, antioxidant activity and lipid parameters of blood in broilers, which 0.6% of seed is advisable.

To evaluate the effects of Elaeagnus Angustifolia (EA) and enzyme on serum biochemistry parameters of broiler chicken, 288 one-day-old male Ross 308 broilers were randomly allocated to 32 cages for 8 dietary treatments with 4 replicates. This experiment were done in a completely randomized design with 4*2 factorial trial involved 4 levels of EA (0, 0.75, 1.5 and 3% EA) and 2 levels of Enzyme (0, 0.05% of Natozyme plus). The data were shown that EA were improved the body weight and feed conversion ratio. Dietary treatment did not affect the triglyceride, and HDL of broiler fed with EA and Enzyme at 28d; but the concentration of LDL and cholesterol was significantly affected, so that the LDL and cholesterol concentration were higher when birds fed 3% EA as compared to birds fed control(P<0/05). The activity of AST and ALT liver enzymes were gradually decreased when birds fed up to 3% of EA. It is concluded that supplementation of EA up to 3% may improve performance and decrease cholesterol and LDL concentration of broiler.

This experiment was conducted to consider of sunflower meal (SFM) levels and protease enzyme on performance, egg quality traits and intestinal morphology of laying hens from 78 to 86 weeks of age. In total, one hundred and twenty white Bovans laying hens were used in 6 treatments, 5 replicates and 4 hens in each in a factorial arrangement 3×2 by completely randomized design (CRD). The experimental treatments contain 3 levels (0, 6.78 and 13.56% SFM) and 2 levels of protease enzyme (0 and 200 g/ton). Results have shown that second level of SFM (6.78%) in the diet increased egg production than control treatment (P<0.05). Feed intake increased significantly (p<0.05) by enzyme supplementation. Increased feed intake by 13.56% SFM with enzyme than 0 and 13.56% SFM without enzyme and 6.78% SFM with enzyme supplementation (p<0.05). Egg quality including shape index, yolk index, haugh unit and shell weight (p<0.05) were improved by protease enzyme. Duodenal villus width significantly decreased by 13.56% of SFM without enzyme supplementation (p<0.05). Height of duodenal villus decreased by enzyme supplementation (p<0.05). The general results have indicated that could be use sunflower meal up to 13.56% with enzyme in laying hens diet without any adverse effect on performance.

To evaluate the effects of Primalac probiotic and Fermacto prebiotic, alone or combined, on growth performance, ileal nutrients digestibility, intestinal mucosal morphometry and some blood biochemical parameters, a trial was conducted using 256 broiler chicks (Ross 308) by employing a completely randomized design. Four treatments including Avilamycin antibiotic (control), Perimalac, Fermacto and Perimalac plus Fermacto with four replicates were added to the basal diets and fed to birds for a period of 42 days. Primalac and Fermacto decreased feed intake (P<0.01) and lowered weight gain of the chickens (P<0.001). Feed conversion ratio was depressed by Perimalac containing diets as compared to the control (P<0.05). pH value of gizzard and cecal digesta was not affected by the treatments. Ileal digestibility of energy was decreased by the experimental treatments (P<0.05). Decreased villus height as the effect of Perimalac and Fermacto and increased crypt depeth as the effect of all treatments were observed (P<0.01). Applying Primalac, Fermacto and their combination in the diet declined total and LDL-cholesterol levels (P<0.001) while these two additives alone enhanced HDL-cholesterol levels of broilers sera (P<0.05). In overall, using Primalac and Fermacto alone or combined, except lowering effect on serum cholesterol, failed to show any similar effects as Avilamycin on broilers performance. In conclusion, Primalac and Fermacto could not be replaced for the growth promoter antibiotic. Moreover, no synbiotic characteristic was observed between Perimalac and Fermacto.

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.
