Abstract

The sheep industry is growing fast in Brazil but it faces important problems like the resistence of endoparasites to drugs and low reproductive performance, especially in Santa Ines breed, the most important hair sheep of that agribusiness. So, this research aims to find new approaches to help to solve those problems, finding DNA polymorphisms linked the Major Hystocompatibility Complex and to resistence to Haemoncgus contortus and others, like BMP-15, BMP-1B and GDF-9 and verify their association to prolificacy in Santa Ines sheep.
