Studies On The Taxonomy And Prevalence Of Eimeria Species And Their Effect On Total Serum Protein In Commercial Layers
1998
The present project was designed to study the prevalence of Eimerian species in layers of different age groups arid breeds. For the purpose, 500 carcasses of layers were obtained from various sources and brought to the College of Veterinary Sciences Lahore, and opened in Paraisitology Laboratory. Different parts of intestine were examined for the presence of Eimerian species. In addition, to asses the general health status of birds, relationship between oocyst count and total serum protein, 30 different layer farms were selected randomly and from cacti farm 5 birds were subjected to faecal arid blood examination. The faecal samples were checked for the presence of Eimerian. oocysts arid their count par gram of faeces. The serum wan separated from the collected blood sample and total serum protein value was calculated. The managemental factor of these 30 Farms were also recorded.
Five species were isolated from the 500 carcasses on the basis of site of infection, oocyst shape, size, length/width ratio and sporulation time. These specie5 included Simeria tenella 32.40%, C. acervulina 29.62%, C. necatrix 15.68%, C. brunetti 13.59% and C. maxima G.71@.
Out of 30 farms, 13 farms were found positive for coccidiosis. Correlation was found between the values of oocyst count and total serum protein. Five farms showed positive correlation which indicated that there was no significant difference between oocyst count and total serum protein values. Eight farms showed negative correlation indicating significant difference between the relavtive values of oocyst count and total serum protein.
It was found that layers between 3-9 weeks of age were most susceptible to coccidiosis. ESb3 was found to be the most effective and commonly used drug. Among different types of litter being used in the farms, rice husk was found to be the best bedding. Babcock was found to be the most resistant breed in layers. It was also observed that inadequate space provided to the birds, uncontrolled temperature of the farm and inadequate number of drinkers and feeders favoured the infection. Biosecurity measures remained the most important among all the factors.
