This study was carried out to determine the effect of the herb and Urtica dioica of the vitality of the Eimeria tenella, it conducted on 150 Ross broiler chicks, divided randomly on the seventh days into six groups. The last two groups (five and six) were considered as a positive and negative control groups, the first five groups were experimentally infected by 1000 oocysts/bird of Eimeria tenella at 17 days old directly in to the crop. The first four groups were given Artemisia herba alba and Urtica dioica According to concentrations for each group. Results were indicated a higher significant differences ( P

Essentiaol oil of thymus vulgaris and origanum vulgare were extracted by hexane and analyzed to the component by GC-MAS Gas chromatography. in vivo study was done on seventy two healthy mature non pregnant female rabbits. Animals were divided into nine groups of eight animals for each one. the first group was injected by 0.1ml physiological saline vaginally and served as a negative control group. All other eight groups were immune suppressed by drenching each animal with (5 mg/kg) dexamethasone once daily for 7 days ,group 2 considered as a dexamethasone control group. Other seven groups were infected vaginally with Candida albicans by (1.5)×〖10〗^8 candida cells/ml once daily for 7 days group 3 considered as vaginal candida (positive) control. The sixth groups then treated once daily for 14 days with ( 0.1) ml of oils according to each group:- group 4 was treated with thyme oil orally, group5 treated with thyme oil vaginally ,group 6 treated with oregano oil orally, group 7 treated with oregano oil vaginally, group 8 treated by oral nystatin, Group 9 treated vaginally with nystatin. Blood was drawn from animals at the end of the experiment all experimental animals were sacrificed and pituitaries; ovaries and uteri were collected and fixed in 10% formalin for histological technique. result explained that candidiasis caused significant increase in progesterone, LH and FSH also decreased in estrogen compared to control. Treatment with thyme or oregano oils by two routs showed decrease in progesterone and an increase in estrogen than candidiasis group. So FSH and LH decreased in groups treated with two oils compared to candidisasis group but not reached to normal level. Nystatin decreased all reproductive hormones. results showed improvement of organs structures in treated with thyme or oregano oils

Ten samples of baffula stomach including rumen, reticulum, omasum Abomasum were collected from slaughter of Basrah .Tissue sections were done and stained with alcian blue and acridin orange dyes then photographed by light and fluorescent microscope .The histochemical study showed that all four parts of stomach consist of mucosa,submucosa ,muscular and serosal layer .The histochemical study showed that mucopolysacchrides distributed in all histological layers but with high density in the mucosal layer.

The study was conducted on (96) local sheep breeds of different ages and both gender reared in Basrah, Iraq. Suspected animals show signs of night blindness, abortion of pregnant ewes, diarrhea with passing of normal small fecal materials ,nervous sings (such as paralysis of skeletal muscles, blindness due to constriction of the optic nerve canal, convulsions encephalopathy). Moreover diseased animals were also show panting and changing of skin .The levels of vitamin A and Beta carotene were estimated by ELISA test and results showed that local sheep suffer from hypo vitaminosis A with mean level of( 1.8 nmol/l). However according to regions of Basrah deficiency of vitamin A and carotenes respectively were indicated of center of Basra (1.7nmol/land 11.2 ng/ml). AlQurna (1.7 nmol/l and 15.9 ng/ml) .Azzubair (2.1 nmol/l and 26.3 ng/ml). Shateelarab (1.2nmol/l and 17.7 ng/ml).and Abulkhaseeb (2.0 nmol/l and 16.8ng/ml) It have been concluded that local sheep breeds of Basra province were suffer from hypovitaminosis A, therefore animals reared in those area should be screened periodically.

The aim of study was a histopathological evaluation of the effects of low-level laser therapy (LLLT) such as diode laser on healing fracture of distal third of the radius in dogs, at the end of 1st,3rd and 6th week post operation .18 male adult street dogs were used to obtained transverse fracture at the distal third of the radius under highly aseptic technique, the anesthesia was done by using the combination of (15 mg/Kg.B.W ) ketamine hydrochloride,and (5 mg/Kg.B.W ) xylazine, the fractured limb fixed with (Gypson) as an external fixation devise, and window is obtained at the anterior surface of the radius at the fracture sites for direct irradiation of the laser. The experimental animals were divided into two equal groups each contain 9 dogs, the control group lift without any irradiation, while the treatment groups received daily single dose of laser (850 nm, for 5 minutes at 72 hours interval for 14th days). Histopathological finding at the end of the 1st week revealed early formation of irregular trabecular bone (immature woven bone), compare with the control group at the same period, then these trabecular bone became later more regular, dense and width at the end of the 3rd week in the treatment group, then quickly changed to lamellar bone in the end of the 6th wk P.O. in the treatment group compare with the control group. It concluded that The LLLT promote and accelerate fracture healing, in the distal third of the radius in dogs

The current study was aimed to investigate the development of testis during pre-hatching periods to diverse the components of the testis in duck embryo from embryonic day 5 to 19 consequently; fifteen males' of mallard ducks embryos have been used. The results showed that development of testis has divided into two periods: the first one was the period of undifferentiated gonad (genital ridge) while the second period was the development into a testis which showed various stages. The undifferentiated stage has revealed of development a small protruded thickening of germinal epithelium and primordial germ cells on the ventromedial surface of the mesonephros and dorsal mesentery.The development periods has showed three stages: development of rete cords, sexual cords,primary somniferous tubules and Sertoli progenitor cells at the 8-10th day embryos. During 14th day old embryo was revealed of development immature somniferous tubule, tunica albuginea and testicular capsule. While the period of 19th day embryo showed that development of interstitial cells and thin septa from tunica albuginea, .in addition to marked division of spermatogonia cells. Size of left testis was larger than the right one also the epithelial layer of left gonad is thicker than that covering the right gonad.

The comparison toxico-epidemiological study designed to evaluate the Lead, Nickel and Cadmium levels in healthy sheep of different regions in Al Basrah province and compared with sheep from Animal Farm of Agriculture College /University of Basrah(as control group). Sixty three adult male sheep were tested for the study (6 animals for each region). Blood samples were collected from each ram, the Pb, Ni and Cd values were measured. AST, ALT and creatinine values were also determined. The results revealed to high increase levels of Cd, and Pb concentration among the different regions and compared with control rams values. There were no significant differences in the transaminase enzymes activity and creatinine concentration among the animals tested. In spite of the rise in trace minerals values but it did not threshold to harmful effect on rams’ body physiology.

This study was carried out to evaluate the effects of locally produced fish biosilage as fish meal alternative on feeding, growth efficiency and gut histology in common carp C. Carpio fingerlings. Biosilage was prepared by fermenting marine by-catch fish with date fruit residues, domestic vinegar and citric acid. The produced biosilage was incorporated in feeds to replace 0, 25, 50 or 75% of fish meal protein. Fish were fed for 14 weeks and feeding and growth parameters were close in the four feed groups so as fish survival rate during the experiment (88.9-93.3%). Histological examination of intestine and liver sections has showed improvements when fish fed on the four different feeds. Initial fish group showed signs of nutritional deficiency through limited size of intestinal villi and hepatocytes. However, the histological structure of gut was improved after fish were fed on the experimental feeds without significant differences between fish meal or fish biosilage feeds. The study concluded that fish silage could replace fish meal without adverse effects on feeding, growth efficiency and gut histology.

The present study aimed to determine the macro minerals status ( calcium , phosphorusand magnesium ) in the local buffaloes breed that suffering from uterine prolapse comparedwith other buffaloes withoututerine prolapse. The study started from August 2015 toMay 2016 , and conducted on 100 local buffalo breed, 3-14 years old, reared in Basraprovince (Basra – Iraq ). Animals were divided into two groups, first group included (40 ) diseased animals with uterine prolapse and the second group included ( 60 ) animalswithout uterine prolapse served as control. Diseased buffaloes were diagnosed on thebases of clinical manifestation, since uterine prolapse were evaluated after 6-72 hourspost calving.The results showed that there wasa drastic decrease in serum macro mineralslevels in prolapsed animals, and calcium serum level was (6.31 ± 0.71mg/dl), phosphorus(3.69 ± 0.45mg/dl) and magnesium (2.85 ± 0.18mg/dl) compared with levels of controlanimals that showed (10.02 ± 1.52, 4.97 ± 0.39 , 5.17 ± 0.97) mg/dl of the calcium,phosphorus and magnesium successively. It was concluded that deficiency of calcium,phosphorus and magnesium serum level in the last period of pregnancy and at parturitionmight be possible causes of post calving uterine prolapse in these buffaloes
