An experiment was conducted to evaluate the effect of replacing dietary limestone with Mashhad power plant Calcium-waste in combination with available phosphorus level on growth performance, tibial strength and blood alkaline phosphatase activity in broiler chickens. Three hundred and eighty four male broiler chickens were used in a complete randomized design experiment with a 4×2 factorial arrangement of treatments and four replicates of 12 birds each. Limestone was replaced with Ca-waste source at the rate of 0, 33.3, 66.6 and 100% in combination with two levels of available phosphorus (80% and 100% of Ross recommended) in the starter, grower and finisher diets during 1- 42 days of age.Tibia ash, Ca and P percentage (only treatments contain 100% Ross recommended phosphorus) and sera alkaline phosphatase activity of chicks, were measured at 21 days of age. One bird from each replicate was weighed, slaughtered and carcass weight and carcass cuts were weighed on 42 days of age. Experimental diets were formulated to be isoenergetic and isonitrogenous with similar nutrients with the exception of total phosphorus.The results showed that the dietary limestone can be replaced up to 100% by Mashhad power plant Ca-waste source without any significant effect on body weight, serum alkaline phosphatase, carcass weight and cuts, tibia ash, calcium and total phosphorus. Also feed conversion ratio was significantly influenced by diet phosphorous levels during grows period.

A 3×3 factorial arrangements experiment was conducted to evaluate the effect of Fennel extract and Vitamin D3 on performance, hatchability, chick quality characteristics and Immunity. This experiment was done with using 360 Ross 308 broiler breeders after molting (84 - 92 weeks) in a completely randomized design with three levels (0, 50, and 100 mg/kg of diet) of fennel extract and three levels (0, 3500 and 4200 IU/kg of diet) of Vitamin D3. Fennel extract supplementation of broiler breeder diet decreased initial embryonic mortality in the whole experiment of period. Gender of chickens (male percent), relative chick weight was significantly affected by VitaminD3. In addition, vitamin D3 supplementation in diet caused an increase in Newcastle antibody titer.

This experiment was conducted to evaluate and compare antibiotic, organic acid, probiotic and prebiotic effects on performance, egg quality and blood metabolites in commercial laying hens. The experiment was a completely randomized design with 160 laying hens strain Hy line (W-36) from 32 to 42 weeks of age with 5 treatments and 4 replicates of 8 hens each. The experimental treatments consisted: 1- basal diet, 2- basal diet + 150 g/ton oxy tetracycline antibiotic, 3- basal diet + 3 kg/ton of organic acid supplementation, 4- basal diet + 50 g/ton probiotic (Protexin) and 5- basal diet + 2 kg/ton of mannan oligosaccharide prebiotic. The results showed that the use of antibiotic, organic acid, probiotic and prebiotic have significant effects on performance and egg quality traits. Accordingly, the maximum egg weight was obtained in treatments receiving organic acid and prebiotic that was significant compared to control treatment. Egg mass and feed conversion ratio in treatment received prebiotic significantly improved. The maximum egg shell weight was obtained in treatment received prebiotic that compared to the control treatment showed a significant increase. Between blood factors, glucose concentration in treatment received organic acid compared to control and antibiotic treatments, significantly increased. Consequently the use of organic acids and mannan oligosaccharides can have positive effects on performance and egg characteristics of laying hens.

To estimate the effect of microencapsulated fish oil on blood metabolites, rumen and blood plasma fatty acids concentrations twelve Sannan dairy goats with 30 ± 5 days in milk (DIM) were allocated to 3 treatments in a 3×2 change over design with 2 periods of 30 days. Treatments were: 1) the control (without fish oil), 2) microencapsulated fish oil (2% fish oil capsulated in 6% treated whey protein concentrate, 3) fish oil (2% fish oil and 6% whey protein concentrate). Concentration of C18:0 in the rumen for microencapsulated fish oil decreased significantly in comparison with the control. The same manner was observed in goat’s blood plasma for microencapsulated fish oil. Microencapsulated fish oil led to a significant increase in polyunsaturated fatty acids concentration, hence concentration of C18:3, C20:5 EPA, C22:5 DPA and C22:6 DHA as a source of ω3 fatty acids increased 10, 20, 10 and 13 folds in comparison with the control and 10, 20, 2 and 2.5 folds in comparison with the fish oil treatment, respectively. HDL concentration in protected fish oil was significantly higher than that for the control and unprotected fish oil treatments. It seems that fish oil supplementation caused significant changes in blood fatty acids composition of ruminants as well as ω3 fatty acids in their products. Significant increase of ω3 fatty acids in blood plasma of microencapsulated fish oil treatment showed the protective effect of capsulation against rumen microbial biohydrogenation.

In this research, chemical composition, gas production characteristics, effective degradability and nutritive value index (NVI) of DM and CP by in situ method of treated walnut hull by Nurospora Sitophila were studied. Three fistulated Kermani ram were used for determination of Walnut hull degradability. Data were analysed using completely randomize design. By processing walnut hull with Neurospora Sitophila, water holding capacity and total content of tannin and phenol decreased significantly, while the insoluble ash increased significantly. Processing had no significant effect on degradability parameters and NVI of dry matter and crude protein. Gas production volume in untreated Walnut hull in times 6, 12 and 24 hours increased significantly with comparison to the treated Walnut hull. Generally, processing of walnut hull with Nurospora Sitophila had no significant effect on nutritive value of this feedstuff.

The objective of the current study was to examine the extent of variation of genetic improvement in dam of dams genetic pathway after insemination of heifers with sex sorted semen. For this purpose three different sexed semen based strategies were examined including 1: continuous use of sex sorted semen (strategy CS), 2: use of sex sorted semen for the first and the second inseminations and use of conventional semen for the third and later inseminations (strategy S2) and 3: use of sex sorted semen for the first insemination and use of conventional semen for the second and later inseminations (strategy S1). Predicted values of genetic improvement resulted from the referred strategies were compared to its related values in the case of utilizing conventional semen. Changes in the selection proportion and selection intensity and its effect on genetic improvement were achieved in different scenarios under different conception rates. In all scenarios, genetic improvement of CS strategy was greater than its value in other strategies. Genetic improvement varied in additive genetic standard deviation unit from 0.31 to 0.32 in CS strategy, from 0.23 to 0.30 in S2 strategy and from 0.20 to 0.27 in S1 strategy. Furthermore, predicted genetic improvement in sexed semen based strategies was about 5.82 to 39.65 % greater than its related value when continuous utilization of conventional semen was applied. In spite of enhancing genetic improvement in dam of dams pathway after utilizing sex sorted semen in heifers, changes were not considerable compared with the obtained genetic improvement from other genetic pathways; And a greater genetic improvement is expected from other genetic pathways.

The objective of this study was to evaluate the potential gain in accuracy of predictions by imputing genotypes from a low-density marker panel (6640 marker with 10 replicates) to a medium-density marker panel in a simulated population of Jersey cattle using FImpute software and also to evaluate the reliability of genomic estimate of breeding values (GEBV) for milk yield (h2=0.40) and fertility rate (h2=0.04) with different number of cows in the reference population. A population of 900 medium-density panel of genotyped proven sires was simulated to quantify the accuracy of imputation of reference cows. To evaluate the reliability of GEBVs of 3000 randomly selected animals of test population, nine scenarios were employed. Average accuracy of imputation for cows was 98.64 percent. Only one percent difference observed in GEBVs of 54k and GEBVs achieved for imputed markers. According to high rate of imputation, however, just 1 percent difference obtained between comparing GEBV of 54k and GEBV achieved of imputed markers. Therefore, despite of little difference and although the genotyping cost of a medium-density panel is two-fold of low-density, using of 50K genotyped proven sires plus all cows imputed to medium-density is recommended. Following this procedure, not only the higher rate of GEBV for both traits would be achieved but also by decreasing the cost of genotyping, more animals of reference population would be used in prediction model. The more the reference animals, the more the pedigree, phenotypic and genotypic data are available to predict marker effects and, therefore, genomic estimated breeding value.
