Coccidiosis of Turkeys
Infection of turkeys with Eimeria spp. This disease is not very common in commercially reared turkeys though most turkey growers receive preventative medication for at least part of their lives. Five species of Eimeria have been identified that cause lesions in turkeys, of which two are associated with significant disease effects. E. meleagrimitis affects the upper small intestine, while E. adenoides affects the caecae and re**um. E. gallopavonis and E. meleagridis affect the lower small intestine re**um and caecae, while E. dispersa is found in the small intestine.
Signs
Huddling.
Weight loss.
Depression.
Watery diarrhoea that may occasionally be blood stained or contain clumps of mucus or shed mucosa.
Tucked appearance, ruffled feathers.
Post-mortem lesions
The affected area of intestine shows thickening of the wall and dilation. The contents may be haemorrhagic or be watery with white material shed from the mucosa.
Diagnosis
Signs, lesions, microscopic exam of scrapings (oocysts, gamonts). Differentiate from necrotic enteritis.
Treatment
Toltrazuril, Sulphonamides (e.g. Sulphaquinoxaline), Amprolium.
Prevention
1.always make use of drinker as feeder while brooding combine with round feeder if you don't have cash to purchase the hole feeder. Remove the round feeder after two days to prevent the birds from eating feed mixed with faeces.
2.always have drugs in your store for easy and quick administration in seen sign. Give Amprolium by kepro company because it also treat black head (histonomasis) at 5 days. Don't miss with any antibiotics.
3.The ionophore coccidiostats lasalocid and monensin are routinely used in turkey growers, typically to 12 weeks of age. Diclazuril is also used for this purpose. Dosage levels of ionophores may be critical to efficacy and safety. Exposure of previously unmedicated birds to these compounds can cause toxicity. Salinomycin is toxic for turkeys even at very low doses. Avoid use of tiamulin in ionophore treated birds.
