The current study was conducted in the laboratory of the Faculty of Science / University of Anbar, for the period from 09/27/2012 until 11/17/2012 day for the purpose of comparison methods give treat disease Coccidosis in the productive performance of broiler through the use of 135 chick is one day old unsexal ( Ross strain 308) where distributed randomly to nine treatment and by five replicates per treatment and 3 chicks each repeater (15 chicks / treatment), gavage chicks in treatment first with distilled water (control negative) , and treatment second chicks for by gavage (Intra - Crop) challenge dose for the E. tenella locally isolated and by 5x 104 Oocyst / chick (2.5 ml) at 28 days for the treatment of positive control For the purpose of comparison methods give immunoglobulin IgY locally isolate,
has been giving him a concentration of 11.013748 mg / ml amount of 0.5 ml / chick on all transactions, and in the third treatment given by antibodies capsule was given in the fourth treatment by gavage (Intra - Crop) after administration of 1 ml of acidity equalizer after preparing a tea spoon of equivalent acidity in 10 ml of distilled water (Sodium bicarbonate 2.80 gm, Tartaric acid 1.33gm, Citric acid 0.82 gm, Flavour to 5gm) . In the fifth treatment injected antibodies peritoneal membrane, and the sixth-treatment antibody was injected in the muscle (thigh, chest, neck) and in the seventh treatment injected objects counterrevolution in the yolk sac one day old and in the eighth treatment antibody injected under the skin (thigh, chest, neck) and in the ninth treatment antibody was injected intravenously.
Notes from the current results of the experiment that the antibody injection in peritoneal membrane has led to a significant increase in body weight and the weighted increase in the seventh week of life compared to the rest of the transactions. In addition, got a significant increase (p> 0.05) in cumulative feed conversion ratio while significantly decreased the proportion of cumulative mortality (1-49 days) in the treatment of peritoneal injection and yolk sac injection treatment compared to the rest of the treatment. Inferred from the current study that giving intravenous IgY peritoneal membrane was significantly better than the rest of the transactions in its effect on the productive performance down Representative proportion of cumulative mortality and improve feed conversion efficiency, which is reflected in the body weight and increase the cumulative weighted.
