The problem of coccidiosis in broiler chickens and laying hens: Selected control methods and alternative solutions
In industrial poultry production, especially in broiler chickens, coccidiosis, caused by Eimeria protozoa parasites in the digestive tract, continues to be a serious health and economic problem. In economic terms, the losses are mainly caused by the costs of prevention and treatment, as well as the reduced weight gain and reduced condition of the birds. Currently, the prophylactic program of this disease unit is mainly based on the use of chemotherapeutics. Another way to control coccidiosis is active immunoprophylaxis, based on the vaccination of chickens for fattening, and passive immunoprophylaxis, based on vaccination of the parent flock. An alternative, effective way to reduce the negative effects of protozoan infestation by Eimeria may be the use of herbs and their extracts, pre- and probiotics and betaine.
