Abstract In addition to being a rich source of nutrients for newborn mammals, colostrum has important immune factors that are important for overcoming challenges in the first weeks of life. The quality of colostrum depends on some factors such as age, race and number of pregnancies. High concentrations of immunoglobulin G (IgG) determine, normally, a high quality colostrum. However, the relationship between this variable and other proteins present in colostrum still needs to be better exploited. Thus, this project will determine the relationship between the immune quality and the profile and concentration of proteins in colostrum of primiparous and multiparous cows. The experiment will use a group of 16 cows, being 8 primiparous and 8 multiparous, Holstein-Jersey crossbred. Colostrum samples will be collected immediately after birth for the determination of proteins by SDS-PAGE. In addition, the IgG concentration will be determined and related to proteins present in colostrum. | |
