The invention belongs to the field of poultry breeding, and relates to a molecular marker for indirect selection of Eimeria tenella resistance and its application. The molecular marker for the indirect selection of Eimeria tenella resistance in chicken is the genotype TT formed by the SNP mutation at the 5' regulatory region of the chicken interleukin 8 gene -360bp. The present invention provides a molecule that realizes the indirect selection of resistance indicators under non-challenge conditions, improves the coccidia resistance of selected groups of chickens, and can breed new varieties or strains of Eimeria tenella resistance indirect selection labeling and application.
Description
A molecular marker for indirect selection of resistance to Eimeria tenella in chickens and its application technical field The invention belongs to poultry breeding field, relate to a kind of molecular marker and application, relate in particular to a kind of chicken tender Amy Molecular markers and applications for indirect selection of Coccidia resistance. Background technique Chicken coccidiosis is a kind of epidemic acute parasitic disease that seriously harms breeding enterprises. The disease rate is the highest, and the main features are weight loss, loss of appetite, anemia and bloody diarrhea. will be affected. The world's annual economic loss caused by chicken coccidiosis is as high as 3 billion US dollars, and my country is used to prevent and control it every year. The drug cost of chicken coccidiosis has also reached hundreds of millions of yuan, accounting for nearly one third of the total cost of chicken disease prevention and control. For a long tim...
