Serum Free Amino Acid Concentration in Hepatic Lipidosis of Dairy Cows in the Periparturient Period

Metabolomic biomarkers correlating with hepatic lipidosis in dairy cows

BACKGROUND Hepatic lipidosis or fatty liver disease is a major metabolic disorder of high-producing dairy cows that compromises animal performance and, hence, causes heavy economic losses worldwide. This syndrome, occurring during the critical transition from gestation to early lactation, leads to an impaired health status, decreased milk yield, reduced fertility and shortened lifetime. Because...

Concentration of Free Amino Acids in Blood Plasma of Dairy Cows with Developing Hepatic Steatosis

Pechová A. , J . I l lek, I . Li‰ka, R. Halouzka, L. Pavlata: Concentration of Free Amino Acids in Blood Plasma of Dairy Cows with Developing Hepatic Steatosis. Acta vet. Brno 2000, 69: 93–99. The aim of this experiment was to study the changes in free amino acid (AA) concentration in blood plasma of dairy cows developing hepatic steatosis after parturition and to establish the diagnosis by mea...

Dairy cows experience selective reduction of the hepatic growth hormone receptor during the periparturient period.

At parturition, dairy cows experience a 70% reduction in plasma IGF-I. This reduction coincides with decreased abundance of GHR1A, the liver-specific transcript of the growth hormone receptor (GHR) gene, suggesting impaired growth hormone-dependent synthesis of IGF-I. It is not immediately obvious that the periparturient reduction in GHR1A is sufficient to reduce hepatic GHR abundance. This is ...

P-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...
