This experiment was conducted to compare and estimate the fertilizing capacity of native with New Hampshire chicken semen. Also to study the effect. Of different levels of semen dosage on fertility percentage, duration’ of fertility and duration of fertilizing ability. In this experiment (12) native and (12) N.H. male chicken with (240) Hisex laying hens have been used. The results of the statistical analysis showed that there were no significant (P>0.05) differences between the native and N.H. male chickens for the fertilizing capacity. fertilizing percentage in duration of fertility and fertility duration. The values were 90.40, 90.73%; 85.77, 85.60%; 12.11, 12.3 days for native and N.H. chickens, respectively. There were no signi

The estrous cycle of 8 Arabian mares was followed for one year, by visual observation of the estrous behaviour and by teasing with a stallion. Serum progesterone concentration was determined by RIA, Vaginal electric resistence was studied with aid of Ovascan, comapared with the changes in the reproductive tract as determined by rectal examination for prediction of ovulation. The changes in the reproductive tract and the behavioural manifestations expressed during the cycle indicated that the experimental mares were exhibiting estrous year arround, however, 75% of the cycles were observed during the months from March to August and 25% during the. rest of the year. The total number of cycles exhibited by the mares averaged 68 cycles, of th

The present study was intended to evaluate the prophylactic effects of two anticoccidial drugs (monensin and amprolium) on experiinental infection with Eimeria tenella in chickens. Twenty one day-old chicks were used, they were divided in two main groups (floor and battery brooders rearing) with 112 chicks for each group. Each group was subdivided into four subgroups represent, control, infected nontreated, treated ‘with monensin and treated with amprolium. Monensin was given at rate of 100 ppm in ration while amprolium was given at a rate of 125 ppm in drinking water. The birds were infected with 50.000 sporulated oocystes/bird at 25 days of age injected directly into the crop. The following parameters were used to evaluate the drugs;

Infectious bursal disease is one of the diseases frequently diagnosed in broilers chickens in _ Iraq depending on pathological changes in the bursa of Fabricius. It is known that maternal antibodies may interfere with the clinical signs, severity of the infection as well as the responsse of chickens to live virus vaccines. Therefore, serological surveys are of value in determining the prevalence of antibodies to this disease. The agar jel precipitation test was used in this survey because of its simplicity and specificity for detecting antigen-antibody reactions. Serum samples were collected from chickens brought to the veterinary hospital in Baghdad. Precipitation lines appeared between positive serum and antigen prepared from infected

An infectious syndrome of broiler chickens characterized by. stunted growth, poor feathering, leg weakness, poor feed conversion, and loss of pigmentation of the skin. The syndrome was initially reported in Netherland (Kouwenhoven et al., 197848), and have since been described in England (Bracewell and Wyeth, 1981), U.S.A. (page et al., 1982), Australia (pass et al.,1982) and Canada (Riddell and Derow, 1982). The various names of the syndrome reflects the variety of clinical signs and gross lesions .observed, and although reported conditions share many clinical signs and pathological changes, it is not certain that all reports describe the same disease entity.

A group of 15 Awasi ewes were inserted with intravaginal sponges of Veramix plus which were removed thirteen days later. Immediately after removal of the sponges, they were injected with 500 IU of FSH intramuscularly. All ewes were came to estrus within 2-3 days after injection. They were serviced, then, after completing a successful pregnancy, all ewes had twin lambs. : This trial indicates the success of estrus synchronization in ewes.

Cyclopia is a congenital defect in which the two orkits merge to form a single cavity containing one eye, which is likely to show more or less evidence of its origin by fusion of the right and left optic primordia. It is usually combined with cyclencephaly. It is usually described as synophthalmus.

Twenty one male goats 3-4 months of age were exposed to five metacercariae per kg. of body weight of two isolates of Fasciola gigantica obtained from sheep and buffalo. Eosinophilia was mostly marked after prepatency in goats infected with sheep isolate.

Out of 704 sheep examined from three provinces (Baghdad, Hilla and Diala) in the central part of Iraq, 323(45.88%) were infected with Theileria  hirci, 80 (11.36%) with Anaplasma ovis and 19(2.70%) with Babesia motasi. The percentage of sheep infected with Th. Hirci was much higher (P < 0.01) than those with A. ovis and B. motasi. The rate of infection with Th. hirci and A. ovis but not B. motasi increased with advancing age. There was no significant (P>0.05) difference in the rate of infection between males and females

In an experiment designed to study the pathogenicity of two isolates of F. gigantica, one of sheep and the other of buffalo origin, twenty-one, 3- months old goats were divided into 3 equal groups. The first received 5 metacercariae per kg body weight of the sheep strain and the second group has given the same dose of buffalo strain, while the third group was left as control.

The main pathological findings were characterized as: fibrinous. perihepatitis, haemorrhagic tracts, haematomas, focal necrosis, hydroperitoneum and in the chronic phase by fibrosis and the typical pipe-stem liver. In animals of the second group, lesions were minor and consisted only of fewer heemorrhagic foci.

 The possible explanation of the d

A synthetic prostaglandin F2 α(PGF₂  α) analogue, luprostiol^* , was used in treatment of clinically anoestrus Arabian mares that suffered from abnormal persisting luteal function. Thirty two anoestrus mares were selected for this study after careful examination of their breeding history and a thorough genital examination which included rectal palpation of the genital tract and ovaries. The genital examination also included a vaginoscopy of the vagina and cervix. These mares were diagnosed as clinically anoestrus during the spring and summer months breeding season and received a single intramuscular injection of the prostaglandin F2 α. Twenty six mares (81%) responded to the treatment and came to oestrus with

Hematological values for sixty clinically normal Arabian bred race horses of both sexes were estimated.Red cell ,count, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean ‘corpuscular hemoglobin concentration, white cell count, differential leukocytic count, total serum protein, albumin and globulin were determined by using several laboratory techniques. It appeared that the total serum protein and globulin were significantly higher in the stallions than those in mares (P < 0.05) whereas the results of other hemaltological parameters were comparable and the mean values did not show significant differences (P > 0.05).

Spores of Bacillus subtilis HU1 suspended in whole milk and /or distilled water subjected to high and ultrahigh temperatures ranging from 85 to 14°C. Resulting survivor and thermal death time (TDT) curves were shown to be non-linear for all temperatures investigated; convex survivor curves at most heating temperatures were observed. TDT curves observed in all studies were concave and biphasic. The z-value using milk as the menstruum were 57°C for heating temperatures of 121-140°C, and 20°C, for heating temperatures of 110-121°C. Distilled water as the menstruum yielded z-values of 58°C and 16°C for heating temperatures of 120-140°C and 110-121°C respectively.

Unilateral. thoracotomy was performed in twenty nine donkeys and twenty five horses aged 4-10 years without an ‘aid of positive ‘respirator. Surgical pneumothorax did not endanger the life of patient. Eighteen horses and twenty four donkeys became clinically “normal and the wounds were completely healed within 30 days, however, two horses .dies due to pleurisy. Five horses and five donkeys were killed and subjected to anatomical studies to find out if .there is a communication between the plural sacs or if the mediastinum is not strong enough to resist pressure. Observations indicate that there is no communication between the two plural sacs and that the mediastinum is strong enough to resist the difference in the pressure of the p

Cheddar cheese was made from milk which had been inoculated with psychrotrophs 48hr.. prior to pasteurization. This was compared to ‘control cheese. The cheese was stored at 7 °C and evaluated at 0, 5, 30, 60 and 180 days. ‘All cheese made with psychrotroph-treated milk had significant lower flavor score than control cheese. The predominant flavors of the 180 day-treated cheese were bitter and unclean. High performance. liquid chromatography (HPLC) analysis indicated significant increases of citric, pyruvic, lactic, formic, acetic and propionic acids with ‘aging of Cheddar cheese. Only orotic acid decreased with aging. The control cheese had lower values than the treated cheese for pyruvic, lactic and formic acids. The control che

Sers. from 525 Arabian horses were tested for the presence of antibodies to Toxoplasma gondii by the indirect haemagglutination test. Of these sera, 39(7.43%) were positive. Thirty eight (8.15%) of seropositive animals were horses of two to 13 years of age and only one of the yearlings (1.5 year old) was seropositive. Twenty six of males (6.57%) and 13 cf females (10.08%) were seropositive. There was no significant (P)0.05) difference in the prevalence of toxoplasmosis between males and females.

The effects of single cell protein (SCP) were studied in Al-Awassi lambs in Iraq. Four groups of lambs received 0%, 5%, 10% and 15% of (SCP) as a replacer for a soybean. The influence of (SCP) on the performance and carcass data of lambs and their blood pictures were studied. The total uric acid, blood urea and the histopathological changes were also investigated. The results - showed” that ‘there were no significant (P>0.05) differences ‘among the initial, slaughtered, total weights gained and chilled carcass weights. The wholesale cuts showed. no significant (P>0.05) differences. The eye rib area, fat  thickness of. longissmus doris muscle, average percentage of organs and offal dressing percentage (calculated in live

This study was carried out to determine the feasibility of dry poultry manure (DPM) as a feed stuff. Three types of DPM were studied: 1- layer litter manure, 2- caged layer manure, 3- processed caged layer manure. Three hundred fifty one-day old broiler chicks were allocated at random into seven dietary treatments, chicks in T1 (control) were fed on ‘starter and finisher commercial diets. Chicks in T2 and 13 were fed diets supplemented with 5% and 10% layer litter manure, respectively. Chicks in T4 and T5 were fed dies contained 5% and 10% caged layer manure, respectively, while chicks in T6 and T7 were fed diets contain 5% and 10% processed caged layer manure, respectively. Body weight gain, feed consumption and feed efficiency of the

Blood serum samples were obtained from ten normal nonpregnant ewes at mid January and mid August. The level of acetylcholine estrease (ChE). enzyme activity was estimated colorimetrically while the values of glutamete-oxaloacetate transaminase (COT), glutamate-pyruvate transaminase (GPT) and alkaline Phosphatease (A Ph) were estimated by an autoanalyzer. The results indicated significant depression in the normal values of ChE, GOT and GPT in summer season.

Parathyroid gland of ten adult one-humped came] has been collected from the slaughter house. Glands have been fixed sectioned and stained by several procedures. The gland measured 1.2 cm in length, 0.4 cm in width and 0.25 cm thick. It differs in position from left to right side due to displacement of thyroid gland. The gland consisted of aggregate of cells arranged as solid masses, clusters, cords or strands. The parenchyma of the gland appeared with different cell density. Four cell type has been distinguished, viz., light as well as dark chief cells, oxyphils and syncytial cells.

Naturally infected large intestine of 16 mules were collected during one year period. All three species of Strongylus were identified: S.vulgaris, S.equinus and S.edentatus. Specimens were processed for standard histological examination. The effect of the parasite on the wall of the intestine ‘included the _ surface epithelium, glandular tissue, muscularis mucosa and part of the submucosa. Changes on the intestinal wall were observed at the site of the parasitic attachement, which included oedema, cellular infilteration with congestion and haemorrhages.

Little information is available on the pathophysiological changes caused by Fasciola gigantica. The present study aimed at the ellucidation of these changes in Awasi lambs infected with various doses (100, 300 and 600) of metacercariae.

The radio-isotop (Fe5%) was used to reveal the ferrokinetic pathway in the blood stream of sheep as a result of infection.

All lambs exposed to 100 metacercariae showed the chronic phase of the disease. Of the group exposed to 300 metacercariae, two lambs suffered the subacute phase and the remaining three had the chronic phase. Out of the five lambs given 600 metacercariae, four showed acute syndrom, while the fifth showed the subacute phase of the disease.

Out of 225 specimences taken from nasal, Vaginal, eye swabs, milk synovial fluid and from internal organsof horses. Twelve isolates were recovered as follows 9 isolates from nasal swabs, 3 isolates from vaginal swabs. No mycoplasma isolates were recovered from milk and internal orgxuns. All isolates have been tested for thier reversion to bacterial form. These isolates were purified and biochemical characterized. Six isolates “were fermented glucose, two isolates were diaminted arginine and non of these isolates did reduced tetrazolium. Six of these isolates were resistant to digitonin while the rest were sensitive.

This study was conducted at the turkey farm of the college of Agriculrure? Salahaddin University, by using (7) black and (10) red local turkey toms to study the effect of strain and environmental temperature on semen volume, time needed for semen collection, frequency of massage and percetage of successful trail, and to study the relation beteen pairs of characters under study.

Analysis of variance showed that aenadnie had a significant effect (P<0.05) on both percent of successful trails and the time needed for semen collection, and highly significant (P<0.01) on frequency of massage while it was not significant on the volume of semen.

Effect of environmental temperature showed a significant effect (P<0.05) on t

The incidence of gross ovarian diseases were survid by studying 500 specimens obtained from Babylon slaughter house. The results of the study indicated that the incidence of the ovarian hypofunction (15.2%) was the highest, followed by cystic ovaries (2.8%), whereas the incidence of the ovarobursal adhesions was low (1.8%), while that of the parovarian cysts and cystic corpora lutea were lowest (1%). Additionally, the dimensions and content of the normal ovaries were included in the present study.

This study was undertaken to evaluated vaccinating pregnant cows with "coligen" produced by "Fort Dedge Co." against colibacillsosis in newly born calves. The vaccine was given twice in the last two months of pregancy. Another group of pregnant cows were used as a control. Titration of antibodies was done in the sera and colostrum of the vaccinated and controlled animals and also in the sera of the newly born calves. There was significant rising in antibodies (P<0.01)in the vaccinated animals. These antibodies were protective. Calves receiving colostrum from vaccinated animals were to a certain degree protected aginst colibacillosis. Challenge experiment showed that 36 out of 43 calf of the control group developed diarrheal condition

Four Friesian bulls 3-6 Years old four Friesian heifers 18-24months old were used in this study. Three bulls were injected with 3 ml 3 davs old Mycoplasma bovigenitalium strain AL culture. One bull served as a control which recived broth only. Mycoplasma bovigenitalium organisms serologically similar to the injected strain was isolated from the experimental bulls. All the bullsshowed clinical signs of seminal vesiculitis with varying degress. Two of the infected bulls were left to service 4 clean virgin heifers for four months. All heigers required more than three services to concieve. Mycoplasma bovigenitalium serologically similar to the experimental strain was isolated from three cows at different periods.

Globule leukocytes were detected in the epithelial mucosa of the biliary system of sheep infected with liver flukes. Histochemical investigations revealed cytochemical similarities between the globule leukocytes and mast cells of the biliary system. Both the intracytoplasmic granules of the mast cells and the globules of the globule leukocytes contained a sulphated acidmucopolysacchride assosiated with a highly basic protein.

The clinical, microbiologic and pathologic findings of swollen head syndrome in broiler chickens in Iraq are reported in this study. A consistent clinical feature of this syndrome was swelling of the face. The facial subcutaneous tissue, conjunctivae and nictitating membranes were edematous. Microscopically, there was acute or chronic dermatitis and cellulitis characterized by necrosis of the dermis and subcutaneous tissues, with infiltration by heterophils in acute cases and by macrophages and giant célls in chronic cases. Esherichia coli was constatnly isolated from the facial subcutaneous tissue.

Tetrameres was diagnosed in a free-range-reared chicken. Macroscopically, there were dark spots on the subserosal surface of the proventricular wall; small dark red nodules were present on the cut surface of the proventricular wall. Histologically, each of the nodules was a Tetrameres female in a greatly distended lumen of a gastric gland lobule.
