Material type: materialTypeLabelBookPublisher: 2013Subject(s): Department of Clinical Medicine & SurgeryDDC classification: 1565,T Dissertation note: Coccidiosis is one of the most economically important parasitic diseases of small ruminants and infection may cause subclinical production losses to sheep and goat industry.Coccidiosiscause a serious threat to livestock productivity, due topoor feed utilization, stunted growth, poor weight gain, associated morbidity, mortality, and cost of treatment and control measures. The disease is worldwide in distribution and is caused by many species of Eimeria which invade cells of intestinal epithelium. To treat and control coccidiosis in sheep and goats, numerous drugs were found to be effective including Amprolium, Toltrazuril, Decoquinate, Diclazuril and Sulphadimidine. The present study was conducted to determine the prevalence of coccidiosis in Dera Ghazi Khan, for this 752 fecal samples (376 from sheep and 376 from goats) were collected and examined through direct smear method and salt flotation method. Overall prevalence of coccidialinfection was 48.67%, with prevalence of 52.92% for sheep and 44.41% for goats. The prevalence of coccidiosis in sheep was significantly higher (P<0.05) compared to goats. Eleven Eimeria species were identified 6 from sheepand 5 from goats. In sheep the common Eimeria species wereE. ovinoidalis(56.78%), E. ahsata(47.23%), E. parva(35.67%), E. intricate (30.15%), E. faurei(26.63%) andE. pallid (19.09%). In goats the prevalent species wereE. ninakohlyakimovae(68.86%), E. alijevi(59.88%), E. arloingi(53.29%), E. caprina(46.70%) andE. hirci(22.15%). Eimeria infection was significantly high (P<0.05) in female (54.57%; 310/568) compared to male (30.43%; 56/184).The prevalence of coccidiosis was significantly higher (P<0.05) in ?6 month as compared to above 1 year age.A significant difference was found in three feeding systems (i-e) in stall feeding, grazing and both (grazing + stall) feeding system.Coccidiosis was significantly high (P<0.05) in animals with poor and week body condition compared to medium, good and fat animals. A strong association (P<0.05) was observed between fecal score and prevalence of Eimeria infection. Peak prevalence was observed in month of August (68.08% and 60.63%) while low in October (38.29% and 30.85%) in sheep and goats, respectively. In present study threeaniticoccidial drugs were used and the percent efficacy of Furazolidon, Sulphadimidine and Amproliun was 96.34, 95.40 and 98.08 percent, respectively at day 7. Whereas 98.58, 98.03 and 99.55 percent,respectively at day 21.It was concluded from the results that there was no significant difference (P>0.05) among the percentage efficacy of Furazolidone, Sulphadimidine and Amproliun used in these trials. Hematological analysis was performed using Automated Hematological Analyzer. Hematological analysis showed a significant reduction (P<0.05) in total erythrocyte count (TEC) and hemoglobin (HB) content due tococcidiosis. Results show a significantincrease (P<0.05) in TLC, MCV and PCV of infected animals as compared to control negative. Mean lymphocytes, Monocytes, MCHC and MCH counts were also decreased in infected animals. Hematological values of treated animals become normal at day 21stafter treatment.
