digestion. It works only on Apicomplexa protozoans (coccidia, cryptosporidia, etc.). The target dosage must be always expressed as individual daily dosage and never as ration inclusion rate (ppm). The correct dose is 0,5 mg / kg BW / day with a 28 days duration minimum. In light of ration variation and in order to more readily achieve the target decoquinate dosage of 0,5 mg / kg BW a supplementary, pelleted, decoquinate-containing feed was designed. A 1,000 ppm inclusion rate was chosen so that each gram of the supplement delivered 1mg decoquinate. Therefore each gram of supplement mixed in the forage ration medicated 2 kg BW. The objective of this trial was to evaluate the effect of the decoquinate 1000 ppm feed on growth and carcass weight of bulls entering fattening units .The experiment, conducted in fattening units, began in January 2006. 34 Limousin bulls, 8,5 months of age, weighing 253 kg were utilized. 17 head received decoquinate and 17 head served as controls. Supplement containing decoquinate (1,000 ppm) was incorporated in the feed to deliver decoquinate at a rate of 1g / 2 kg BW/head/day for 28 days. There was no evidence of clinical coccidiosis during the trial. Forty-one days from study initiation, the decoquinate and control groups weighed 329 kg and 316 kg respectively. At 103 days on feed, decoquinate-fed bulls weighed 418 kg versus 404 kg for controls. Duration of the fattening period was 360 days for the treated group and 381 days for the control. Carcass weights were 680 kg and 668 kg for the decoquinate and control groups respectively. This study suggests the use of decoquinate at a daily dosage of 1 g/2kg BW/head/day in a supplementary feed (1000 ppm) will improve live weight gain and carcass weight of bulls during the fattening period. 1161 Effects of Imidocarb Dipropionate Use on Tripanosomosis by Trypanosoma vivax in Sheep R. Lira, F. Bezerra, J. Carvalho, H. Alves, C. Rodrigues, J. Araújo, J. Batista Universidade Federal Rural do Semi-Árido, Cincias Animais, Mossoró, Brazil The effects of imidocarb dipropionate use on tripanosomosis by Trypanosoma vivax in sheep were studied. Four male sheep without definite race were inoculated intravenously with 1ml of blood containing 1,25x105 trypomastigotes of T. vivax, and other 4 sheep were used as control. After infection, the presence of trypanosomes in the blood and temperature were recorded daily for a 60-day experiment period. Blood samples were obtained for hematological analysis at 5-day intervals. Fifteen days after infection, period in which the animals were in the acute phase and high parasitaemia, the treatment was made using imidocarb dipropionate (Imizol, 0,025 ml/kg) via deep intramuscular injection. T. vivax was observed constantly in the blood of the inoculated sheep from 4 days after inoculation. The higher parasitaemia occurred between 7 and 15 days after inoculation. Two weeks before the treatment, infected sheep showed anemia and fever. All animals were negative for T. vivax infection without signs of reinfection, from the first day immediately after treatment. Infected animals still presented after the treatment normal rectal temperature, not significantly different from the control group (P>0,05). The same occurred with the hematocrit average values that raised significantly and did not differ from the control group animals. The use of imidocarb dipropionate in the tripanosomosis by T. vivax treatment has presented effectiveness in promoting the disappearance of clinical signs of the disease and parasitaemia.

Vahedi Razi Institute, Parasitology, Mashhad, Iran Prevalence of anti-Neospora caninum Ig G (subclass I and subclass II) was measured in serum samples randomly collected from 1084 dairy cattle from four cities (Mashhad, Neyshaboor, Torbate-heydarieh, Gonabad) of Northeast Iran. The presence of anti-N. caninum antibodies was determined by indirect immunofluorescence - antibody test (VMRD Inc., Pullman,WA 99163, USA) with a cut-off value of 1:200. We randomly compared a few negative and positive samples by another test (Iscom Elisa). In four cities, of the 1084 samples, 178 280 XXV. Jubilee World Buiatrics Congress 2008 (16.42%) were positive. Distribution of N. caninum in four cities indicated range of seropositivity from 15.18% to 27.71%. The percentage of seropositive aborted cattle was 20.23%. The results revealed the presence of N. caninum infection in the herds investigated, drawing attention to its role as a potential cause of abortion in cattle in Iran. Key words: Neospora caninum, epidemiology, cattle, Iran 1163 Evaluation of Anemia and Leucocytes Indexes in Cattle Theileriosis A. Ramin, S. Asri-Rezaie, M. Hemati Urmia University, Animal Science Department, Urmia, Iran Objectives: 1) the frequency of anemia in theileriosis, 2) the parameters influences and severity and type of anemia 3) changes in leucocytes. Procedure: 91 cows with theileriosis and 19 healthy cows as control group were selected. Theileriosis was confirmed by preferal blood smear or schizontes in LN. A 5 ml blood with EDTA was taken from each cow. PCV (%), Hb (mg/dl), WBC (ml), RBC (x106/ml), Ptn (g/dl) and absolute lymphocyte, neutrophil, eosiniphil counts (/ml), MCV (fl), MCH (Pg), MCHC (g/dl) and parasitemia were assessed by the current methods. Results: The mean for parameters in theileriosis were 22.1, 6.8, 7075, 4, 6.4, 3898, 2746, 136, 55.5, 16.7 and 30.5, respectively. Mean concentrations for PCV, Hb, RBC, eosinophils and MCHC were significantly (P24, 20-23.99, 12-19.99 and
Scotland, cryptosporidiosis appears in young calves of 5 to 15 days of age, with a putrid-odor mucoid diarrhea. The differential diagnosis is based on the presence of oocysts revealed at the lab. Clinical cryptosporidiosis generally appears in beef or dairy herds at the end of the calving period when the pressure of infection is at its maximum. Curative treatments in calves are few, difficult to use and often provide poor results. A systematic preventive treatment in suckling calves is also difficult to carry out owing to the constraint of treating them preventively once a day during 7 consecutive days. Moreover, weight loss is often observed. The pregnant Simmental cows were treated with decoquinate at the rate of 1.25 mg/kg BW/day over 28 days prior to calving and for 7 days following it. In these field trials, 120 cows were first treated during two consecutive pregnancies. In these farms, clinical cryptosporidiosis disappeared almost totally. The dosage must be strictly adhered to and the body weight of pregnant cows must not be underestimated (760kg in Simmental). Also it is important to treat before and after calving, cows must be grouped according to their calving date, a cow with delayed calving must be treated till after parturition. Our field trial confirms other trials already run in France and Spain on Beef cows and ewes. Treating cows or ewes with decoquinate 4 weeks before and 1 week after parturition controls cryptosporidiosis in newborn ruminants. 1165 Evaluation of the Persistent Efficacy of CYDECTIN (Moxidectin) 10% LA Injectable against Psoroptes ovis in Naturally Infested Cattle in Belgium B. Losson1 , R. Hanosset1 , M. Lekimme1 , B. Mignon1 , E. Deroover2 1 University of Liege, Parasitology, Liege, Belgium 2 Fort Dodge Animal Health, Animal Health Department, Brussels, Belgium The aim of the study was to evaluate the persistent efficacy of Cydectin (moxidectin) LA 10% injectable (Cyd. LA) in a herd of Belgian White and Blue cattle naturally infested with Psoroptes ovis. The animals were weighed, clinically and parasitologically examined and divided into two groups of 17 (Group 1- all positive for P. ovis) and 23 (Group 2 - 20 positive for P. ovis mite) animals. On day 0, 13 Group 1 animals and 19 Group 2 animals were given a subcutaneous injection of Cyd. LA at a dosage of 1.0 mg/kg bw (1 ml /100kg). In each group, 4 animals remained as untreated controls. Mite counts were performed on days 0, 28, 35, 42, 49, 56, 63, 70 and 77 PT. Mite counts were transformed into mite scores and means were calculated for each group. In both pens an unexpected result was achieved as all experimental animals were found to be negative for live P. ovis mites on day 28 PT. All animals remained negative for live mites until day 42. On day 46 PT, two seeder animals were removed from Group 1 and replaced by one clinically affected and one clinically and parasitologically positive animal. This was not possible in Group 2. In Group 1, all animals remained negative for live mites until the end of the trial on day 77 despite the presence of an actively infested seeder animal; the second seeder animal was found positive for live mites on day 70. In Group 2, all animals remained negative for live P. ovis mites until the end of the trial. This trial indicates that Cyd. LA at a dosage of 1.0 mg/kg bw was highly efficient against a natural infestation with P. ovis in growing BWB cattle and was very well tolerated. The fact that all seeder animals became negative for live P. ovis mites is difficult to explain. Self cure can be observed but this is unlikely in all control animals. The high dosage linked with the use of LA moxidectin could be responsible for the excretion of fairly high amounts of the active ingredient via the urine, faces and skin secretions. The seeder animals could be exposed to fairly high doses of moxidectin. Nevertheless, in Group 1, 2 new seeders animals were introduced; this challenge was maintained until the end of the experiment (day 77). All skin scrapings remained negative for live mites. In conclusion, Cyd. LA at a dosage of 1.0 mg/kg bw provided under field conditions a full protection for at least 77 days in a group of animals under a P. ovis challenge which was continuous from day 46 onwards. Key words: Psoroptes ovis, Cydectin LA, lasting effect, cattle 1166 Liver Copper Status in Sheep with Fascioliosis G. Kojouri 1 , J. Shojai 2 , I. Amani 3 1 Shahrekord University, Clinical Sciences, Shahrekord, Iran 2 Islamic Azad University of Shahrekord, Graduated Veterinary Student, Shahrekord, Iran 3 School of Veterinary Medicine, Shahrekord University, Student, Shahrekord, Iran Fascioliosis is a disease that affects sheep, goats, cattle and many other species. The flukes also can migrate into the bile ducts or through hepatic tissue, leaving large anaerobic tracts and may produce anemia, hypoalbuminaemia, increasing hepatic enzyme and decreasing plasma ascorbic acid concentration. Liver has a major role on energy and protein metabolism and many important enzymes synthesis too. To this respect and to determine the role of parasite on copper status and also the role of this mineral on parasite survival, liver tissue samples were taken from 35 healthy and 35 infected slaughtered sheep. Copper concentration was measured by atomic absorption spectroscopy and data were statistically analyzed by ANOVA at the level of P
