The present study investigated the use of perforated plastic floors with different heights in the broiler performance, surface temperature, air quality, and carcass characters of broilers. Three hundred sixty-seven day-old unsexed chicks randomly divided into 4 groups: control reared on sawdust litter in others used, plastic floors with different heights (5, 10 and 15) cm, for 2nd, 3rd and 4th treatment respectively. The first treatment (sawdust) showed significantly (P < 0.05) increase in body surface temperature, as compared to the plastic floors system treatments, and the three plastic floor treatments affected air quality, with less concentrations of ammonia and carbon dioxide compared to the sawdust. The results showed significant differences (P < 0.05) in the live relative weight, where the treatments T2, T3 and T4 were increase at the age of 35 days compared to the sawdust treatment. We suggested the perforated plastic floors could be a good alternative to promote a better quality environment and superior production rates with improved surface temperature.

This study conducted in the Physiological Laboratory of the Department of Animal Production/College of Agriculture/Tikrit University, with the aim of finding out the effect of the genotype and sex of local chickens and Brahma chickens on some hematological traits. Used 24 blood samples, twelve samples from local chickens and Brahma chicken, with six samples for both sexes. After performing the hematological analyzes, the following results showed A significant effect of the genotype was observed in the TCH, HB, MCV and MCH. Moreover, it showed a significant increasing for domestic chickens compared to Brahma chickens. The total number of red and white blood cells did not significantly affect the genotype. Sex had a significant effect on most of the studied traits (HCT, HB, RBC, MCV, and, MCHC), where males significantly outperformed females. The interaction between genotype and sex had a noteworthy impact (p≤ 0.05) on most ofthe considered characteristics, and it by and large demonstrated a noteworthy diminish within the examined characteristics in female Brahma chickens compared to male and female residential chickens and indeed male Brahma. However, not effect in WBC count. From the results local chickens recorded to exceed expectations in most of the physiological characteristics and for both genders, the immune status of both genetic structure was rise to, and this may show the versatility of the Brahma chickens to the Iraqi airspace.

This study aimed at detecting the effects of COQ10 with and without vitamin E on some semen characteristics of the broiler breeder males. Twenty-five males at 43weeks of age divided into five categories of treatment with five replicates. The first treatment (control group) included drenching with corn oil capsules only. The second and fourth treatments were about drenching with capsules containing the COQ10 enzyme at a concentration of 5 mg / male / day with and without10 mg of vitamin E whereas the third and fifth treatments included drenching with capsules containing the Q10 enzyme at a concentration of 10 mg / male / day with and without 10 mg of vitamin E. This whole scheme of treatments was to study their effects on certain semen and seminal plasma properties. The results showed a significant increase (P<0.05) in the ejaculation volume, both individual and mass motility in addition to sperm concentration, all accrediting the fifth treatment. Furthermore, the results clear a significant decrease in the percentage of dead and abnormal sperms. The COQ10 with and without vitamin E led to improved semen quality marking a reduction in AST and ALT, glucose concentration and total protein with improved antioxidant status referring to a high level of GSH and low MDA. We conclude from this study that COQ10 with and without vitamin E has the ability to improve the semen characteristics of age-old broiler breeder males and can improve the status of antioxidants in semen.

In the dark, the pineal gland secreted melatonin hormone after produced from tryptophan that is Responsible for organizing many vital functions such as Wake up and sleep, circadian rhythm, Immune response and reproduction. As well as that Melatonin act as antioxidant and inflammatory. Thirty-six of 45 days-old Japanese quail male randomly divided to four treatments nine replicates per each. The control treatment consisted of the basal diet and normal water, 2nd treatment of (1%) hydrogen peroxide in drinking water.3rd and 4th treatment the ratio supplemented with (20 mg melatonin / kg diet) with or without(1%) hydrogen peroxide in drinking water. At 28 days, hematological parameters, antioxidant measurement determined and testes histological assessment. From the results noted a significant reduction in the total counting of red blood cells (RBC) and the relative weight of the testicles with a deterioration in antioxidants status, represented by a significant increase in MDA level and a significant decrease in GSH level of with H2O2 treatment . The supplemented of melatonin led to a decrease in the total number of WBC, PCV, and the concentration of Hb. Moreover, the treatment with the use of melatonin led to an improvement in antioxidants indicators represented by an increase in the level of GSH and a decrease MDA level. As the fourth treatment did not record significant differences compared to the first treatment. Adding melatonin at 20 mg melatonin / kg diet lead to significant improvement in area of germinal layer and its thickness.

This study was investigated the protective role of (CoQ10) on reproductive dysfunction of males quail induced by hydrogen peroxide (H2O2). Forty Japanese quail male 45 days old were randomly allotted into four groups with ten replicate one per each , and treated for 28 days as follows : (G1): the first control group (G2): reserved standard ratio and (1%) H2O2 in drinking water. (G3): reserved production ratio + (100 mg Co Q10/kg diet) and (1%) H2O2 in drinking water. (G4): reserved production ratio + (100 mg Co Q10/kg diet) and normal water. The results showed that exposure of birds to H2O2 caused decrease in serum glutathione level (GSH), testosterone, luteinizing hormones (LH) and follicle stimulating hormone (FSH) hormones and this reflects on histology of testis by reducing seminiferous tubules diameter , area of germinal layer and germinal layer thickness. Whereas supplement of CoQ10 caused an increase the concentrations of theses, hormones in-group G4 as compared with group G2. It can noted that an addition was able to restore the oxidative stress birds (G3) to a state close to the natural state (G1). Though testicular histological modifications were made strides in grown-up Japanese quail male treated with CoQ10. In conclusion, the comes about of the display think about appeared that utilize of Co Q10 can easing the pernicious impacts on male regenerative work takingafter introduction toH2O, maybe through enhancement the antioxidant parameters or testicular capacities or other related endocrine organs.
