COCCIDIOSIS; VACCINATION A BETTER OPTION.

Coccidiosis is an intestinal disease affecting birds,its caused by a protozoan parasite of the genus EIMERIA. There are various species of eimeria affecting different segments of the intestine.The parasite is introduced to the flock by ingestion of the oocyst from dropping of infected birds,contaminated litter and bedding.The protozoan parasite effects on intestines results in poor feed utilization and malabsorption due to damage of intestinal lining.The damage to intestinal lining predisposes the birds to cross infection by Clostridium perfringens,which causes necrotic enteritis. The economic implication of coccidiosis on poultry production can be overuled simply by vaccinating birds at day one.This stimulates development of natural immunity against eimeria. This early exposure confers protection on the birds so that the intestinal health is maintained, which ensures that feed consumed is properly absorbed and utilized. Feeding accounts for 75% of cost of production in poultry, it is of pertinent importance that factors that will increase the cost should be avoided. Disease control/ prevention and management protocols should be well planned with strict compliance. Coccidiosis is a global issue and strategies have evolved over the years on management of the disease,vaccination of the flock has been adduced the most effective. Vaccination of birds coupled with moisture management in litters plays a significant role in prevention of coccidiosis.The production of drug-free animals for human consumption has further tipped vaccination as a better option to prevent coccidiosis in poultry. The campaign of no antibiotics and anticoccidials in poultry feed has been incorporated in Japan with the CP Bangkok producing drug-free birds.Dr Kreeta Khanti, a veterinarian and senior vice president stated that 1/2 of the 60 million broiler chicken produced annually by the Charoen Pokphand's poultry operation are now raised without antibiotics and anticoccidials. The company has stated that vaccinating for coccidiosis is a better option,it allows production of drug-free birds without sacrificing weight gain,conversion or profitability. The option of vaccination adds more value to their products and premium price on their products. The consumers today are much more concerned about what they eat,how the products are produced,handled stored and packaged.This awareness has made people kick against unwholesome products and opt in for organic foods/ antibiotic-free animal by products. Animal health is indeed human health.
