Analysis of the causes and prevention of nutritional disorders peripartum cows

The aim of the project is to analyze the parameters of protein and energy metabolism in relation to the incidence of metabolic load in the peripartum period. The focus of this work is to analyze: - the study of rumen degradation and intestinal digestibility of amino acids for selected kids and treatments of protein feeds, - temporal the plasma amino acids dynamics in dairy cows in relation to the level of nutrition and status of intermediary metabolism, - an analysis of limiting amino acids and their substitution possibilities in dairy cows in peripartum period. The aim of project is to verify and propose the system of management and control of energy and amino acid saturation as a tool for nutritional prevention of peripartal and production phase of dairy cows nutrition
