Studies show that when the diet is chosen so that the content of amino acids can fully meet the needs of animals, a high effect is achieved in the growth, performance, and use of the protein. Plant food for pigs deficient in lysine, methionine and tryptophan. Thus, when balancing diets were evaluated in the composition of essential amino acids, primarily to avoid shortages. To do this, use a variety of foods of animal origin, as well as fodder yeast, flour, soy. The aim of this work was to study the effect of the content of essential amino acids in the diet on productive qualities of Large White pigs. In the control group of pigs received a basal diet consisting of wheat bran and barley, sunflower and soybean flour, chalk aft, tricalcium phosphate, and sodium chloride. Pet second experimental group received a balanced diet with a high content of cereal components and a sufficient quantity of lysine. Pigs third experimental group received a diet balanced in essential amino acids by the addition of synthetic amino acids, based on the so-called “ideal” protein. Weight of the animals was determined at the end of each period in the morning before feeding animals. Average growth of pigs in each age is determined on the basis of these data, Сonsumption of a balanced diet with synthetic essential amino acids has increased the weight of the piglets at the age of 120 days by 13.1% compared in the control group. Weight of the animals of the third experimental group was higher than in the control group, 5.37 kg weight at, or 19.1%. The difference in weight between the animals in group 2 and the control group was 3.58 kg, or 12.8% in favor of the second group of guinea pigs. Costs feed units to obtain 1 kg of weight gain of the animals of the 3rd group were reduced by 16,2-20,3%, compared with control animals.

Е. И. Юлевич. Незаменимые аминокислоты в рационах кормления поросят-отъемышей.
Использование синтетических незаменимых аминокислот в рационах кормления поросят-отъемышей обеспечивает увеличение среднесуточных привесов животных на 19,3%. Балансирование рационов с помощью соевого шрота, также оказывает положительное влияние на показатели роста и развития поросят-отъемышей, однако расходы кормовых единиц на 1 кг прироста в этом случае больше на 8,5%, чем при использовании синтетических аминокислот.

E. Yulevich. Essential amino acids in the diet of weaned piglets.
The use of synthetic essential amino acids in the diet of pigs provides increased daily weight gain of animals by 19.3%. The use of soybean meal for a balanced diet also has a positive impact on the growth and development of weaned piglets, but the cost of feed units per 1 kg of gain in this case by 8.5% higher than in the use of synthetic amino acids.
