This experiment was conducted to investigate the effect of using hydroalcoholic sage extract after experimental copper poisoning on performance and blood metabolites of Japanese quail, in a completely randomized design with 320 one-day old Japanese quails in 4 treatments with4 replicates and 20 birds per each replicate. Experimental treatments were: 1) control (basal diet), 2) basal diet + 750 mg/kg copper sulfate, 3) basal diet + 10 g/kg sage extract and 4) basal diet with 750 mg/kg copper sulfate and 10 g/kg of sage extract. The feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) were measured weekly and calculated for starter, grower and whole periods. The results of this experiment showed that in starter period, FI was highest in control group compared to other treatments (P <0.05). In the starter and total periods, the average BWG of birds that received diet contained copper was significantly lower than birds in control and the birds that received diets supplemented with sage extract (P <0.05). In the starter period, the FCR was improved when diets supplemented with sage extract in comparison with the birds that received copper (P <0.05). Higher levels of blood glucose and triglyceride and lower levels of HDL and LDL were observed in birds receiving copper in their diet (P <0.05). The results of this experiment showed that supplementation Japanese quail’s diet with sage extract can improve BWG and FCR in starter period, and it may alleviate harmful effect of copper poisoning.

Abstract
This study was conducted to investigate the effect of dietary supplemented with zinc oxide (0, 40, 80, 120 and 160 mg /kg of diet) and vitamin E (Vit E; α-tocopherol acetate; 0 and 40 IU/kg of diet) on fertility and hatchability of Japanese quails, and growth performance and immune response of ...

This study was conducted to investigate the effect of dietary supplemented with zinc oxide (0, 40, 80, 120 and 160 mg /kg of diet) and vitamin E (Vit E; α-tocopherol acetate; 0 and 40 IU/kg of diet) on fertility and hatchability of Japanese quails, and growth performance and immune response of their progenies. A total of 960 Japanese quails (Coturnix coturnix japonica) 70 d of age were housed in cages and randomly allocated to 10 treatments with 4 replicates of 24 birds in each (sixteen females and eight males). Dietary supplemented zinc and Vit E significantly increased hatchability (P≤0.05). There was a significant effect of Vit E on breeder quails fertility, while zinc supplementation was reduced embryonic mortality at the second stage (10-16 day) (P≤0.05). Supplemental zinc significantly improved feed conversion ratio of offspring in the first three weeks of age, while added Vit E improved feed conversion ratio only in the first week of offspring growth (P≤0.05). Dietary supplementation of Japanese quail’s ration with zinc and Vit E increased immune response of offspring, and enriched Zn content of tibia bone of offspring increased with zinc supplementation. In conclusion, supplementing breeder Japanese quails ration with zinc and Vit E improved hatchability and growth performance and immune response of offspring.

Effect of natural zeolites and nano-zeolite on gut flora, tibia bone characteristics, blood parameters and performance of broilers investigated with 336 male Ross 308 broilers chicks allocated to seven treatments with four replicates and 12 chicks per each. Experimental treatments were control (no zeolite supplemented), natural zeolite (0.5, 1 and 1.5 percent) and nano-zeolite (0.5, 1 and 1.5 percent). Experimental diets had no significant effect on relative weight of breast, thights, liver, abdominal fat, gizzard and carcass efficiency. Zeolite and nano-zeolite supplementation led to significant decrease of total bacteria and E. Coli population (P<0.05). Experimental additives did not show effect on weight, length, volume and density of fresh and dry tibia. Nano-zeolite inclusion increased phosphorus, ALP and AST amounts compared to control group (P<0.05). It could be concluded that nano-zeolite inclusion in broiler diet, promote gut microflora and increased hepatic enzymes activity.

The Effect of various amount of soybean lecithin replaced with egg yolk to protect the ram semen in times of one hour after semen collection, as well as 24 and 48 hours after the semen store at 5°C was evaluated. Semen was collected weekly for 8 weeks from 10 rams with 2-3 years old and average body weights of 64 kg. Semen samples were pooled and divided into 4 parts. Each part was diluted with one of the tris base extender containing 0.5, 1 and 1.5 percent of soybean lecithin and 14 percent of egg yolk. The motility, viability, morphological abnormalities and membrane integrity of spermatozoa and pH of semen were evaluated. The results showed that 1.5 percent of soybean lecithin improved the motility and viability of spermatozoa at the first time (P< 0.05). At the 48 hours after the semen store in 1 and 1.5 percent of soybean lecithin the sperm viability improved when compared with egg yolk treatment (P<0.05). Overall, soybean lecithin is the appropriate replacement with egg yolk and improved the semen quality in times of study. With regard to limitations of egg yolk using with animal source in ram extender, it was recommended to be using the soybean lecithin as the plant source.

In this Research, effect of bovine serum albumin (BSA) on motility and fertility of indigenous rooster spermatozoa was evaluated using 20 and 48 indigenous roosters and hens, respectively. Semen was collected and pooled. In the first experiment, the pooled semen was diluted and divided into four aliquots.The treatments were included the diluted semen without BSA and with 1% BSA; In each group, spermatozoa motility was evaluated during 30 minutes of semen collection and 24 hours after semen storage in 4°C. Spermatozoa motility parameters were evaluated by computer assisted sperm analysis and routine methods. In the second experiment, hens were divided into 4 groups with 12 hens in each group and fresh diluted semen without BSA and containing 1% BSA as well as stored diluted semen without BSA and containing 1% BSA were inseminated. The eggs were incubated and proportion of fertile egg in each treatment group was recorded. By adding 1% BSA into the diluted semen of indigenous rooster, sperm motility parameters and fertility rate were not affected in fresh semen. However, after 24 hours of semen storage in liquid condition, BSA significantly preserved motility and fertility potential of spermatozoa (P<0.05). In conclusion, BSA improved the spermatozoa motility and fertility of indigenous rooster in liquid storage for 24 hours.
