متن کاملP-64: The Relationship between Polymorphism in Gene of Insulin-Like Growth Factor-I and The Serum Periparturient Concentration in Holstein Dairy Cows
Background: One of the most important metabolic factors affecting the reproductive activity is insulin-like growth factor-I (IGFI) concentration changes after calving. Recently, Maj et al. (2008) discovered a significant association between the IGF-I genotypes based on the 5'-untranslatedregion (5'-UTR) of IGF-I gene and the IGF-I blood level. The objective of this study is to investi...
متن کاملTransition Diseases in Grazing Dairy Cows Are Related to Serum Cholesterol and Other Analytes
The objectives of this study were to describe the incidence of postpartum disease and to evaluate the association with serum cholesterol concentrations during the first 3 weeks after calving in grazing dairy cows. The association between non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHBA), calcium and postpartum diseases was also evaluated. A total of 307 Holstein dairy cows from 6 comm...
