Prevalence And Chemotherapy Of Bovine Coccidiosis In River Region - 2013
Bovine coccidiosis-is an infectious-disease affecting cattle and buffaloes resulting in great economic losses to the beef and dairy sector all over the world. Coccidiosis is an intestinal disease and usually associated with poor growth, bloody diarrhea and sometimes death of young animals. As bovine coccidiosis is commonly found in cattle and buffaloes, therefore it severely affects the production of milk and beef in Pakistan.
500 fecal samples-were collected (250 from-cattle and 250 from buffaloes) randomly to investigate the prevalence of coccidiosis in River Ravi Region Lahore. Overall prevalence of coccidiosis was recorded 57.2 % and 58.8 % in cattle and buffaloes, respectively. Slightly high prevalence was found in female animals. Highest prevalence (66.66% and 70.31%) was observed in animals below 6 months of age, while lowest (44.87% and 48.91%) prevalence was found in animals above 1 year of age in cattle and buffaloes, respectively. The study further revealed that highest prevalence occurs in August, followed by September and October while lowest prevalence was observed in July. The infection rate was a little high in crossbred (59.26 %) and Sahiwal cattle (57.89 %) as compare to imported breeds. Seven Eimeria species were identified from fecal-samples of cattle while Six species were identified from buffaloes, where E.bovis and E.zurnii were found most prevalent among them. Coccidiosis was prevalent significantly higher (P < 0.05)-in animals housed in confined-and dirt yard (72.13 % in cattle, 74.13 % in buffaloes) as compare to animals housed on paved (58.49 % in cattle, 61.22 % in buffaloes) and those having outdoor access. Coccidiosis was most prevalent in stall fed (71.64% and 73.68 %) as compare to grazing (28.58% and 31.91%) cattle and buffaloes. Highest (73.07 % and 72 %) prevalence was found in animals with Poor body condition (score-1), while animals with body condition score 3 (Good) were found with lowest prevalence (37.5% and 47.76%). Highest (82.35 % and 84.21 %) prevalence was found in diarrheic while lowest (36.19 % and 42.85%) prevalence was observed in animals with normal fecal score (1) both in cattle and buffaloes, respectively.
Efficacy of different chemotherapeutic agents against coccidiosis in buffalo calves was also determined in current study. Non-significant difference-(P > 0.05)-was observed-in percentage efficacy of all three anticoccidial drugs at day 28 onward, i.e. 100 % for Amprolium (Amprovil), 99 % for Furazolidone (Furasym) and 99 % for Trimethoprim+Sulphadiazine (Trisym). All the three drugs showed satisfactory results against coccidiosis in buffalo calves and no toxic effects were found during and after treatment.
The current study also determined the effects of coccidiosis on various blood parameters of buffalo calves. A significant reduction in Total Erythrocytic Count (TEC), Hemoglobin concentration, PCV, MCH, MCHC and statistically significant increase-(P < 0.05) in TLC, DLC (except Lymphocytes) and MCV was observed in infected animals. Also a statistically significant difference-(P<0.05)-was observed in mean hematological-values of infected not-treated and treated animals at day 28, where treated groups showed an improvement to the normal values.
