Poroshinskay O. The physiological rationale for the use of lysine, methionine and threonine for quail meat production

The paper is devoted to the study of protein metabolism features and functional state of the digestive system of the quail by complex amino acids. Found that feeding quail lysine, methionine and threonine promotes activation of protein metabolism in the body, which indicates the increase in serum levels of total protein, albumin, amino and residual nitrogen, free amino acids. Marked increase in enzyme activity in the digestive organs such as the pancreas and duodenum. When fed with a complex of essential amino acids in quail increased activity of proteolytic, amylolytic and lipolytic enzymes, resulting in them found an increase in nutrient digestibility of the diet (organic matter and protein). This makes the use of feed proteins for normal physiological processes and maximize productivity quail. Adding to feed amino acids in doses: lysine - 0.3%, methionine - 0.2%, threonine - 0.2% increases in body weight increments birds to the improvement of meat productivity. Cost-effectiveness of feeding amino acid complex for growing quail beef productivity is 2.5 USD for one quail.
