На современном этапе ведения свиноводства, в связи с повсеместным разведением мясных генотипов, внедряются прогрессивные технологические приёмы кормления и содержания животных. Развитие отрасли ставит новые задачи по оценке и разработке норм потребностей животных в обменной энергии, незаменимых аминокислотах и других питательных и биологически активных веществах. Целью работы было изучить влияние концентрации обменной энергии в рационе на показатели роста, прироста ткани и скорости отложения мышечной твани у свиней. Установлено, что нормирование комбикормов для молодняка свиней живой массой 20-40 кг по обменной энергии, усваиваемым лизину и другим незаменимым аминокислотам, сбалансированными в соответствии с концепцией «идеального протеина», позволяет удовлетворить их физиологические потребности в данных элементах питания. Скармливание животным комбикормов с содержанием 13,8 МДж обменной энергии и 10 г/кг корма усвояемого лизина способствует получению 621 г среднесуточного прироста живой массы при минимальном потреблении корма (1,44 кг/сутки).

At the present stage of pig breeding, due to the widespread breeding of meat genotypes, progressive technological methods of feeding and housing of animals are introduced. The development of the industry poses new challenges in assessing and developing standards of animal needs for metabolizable energy, essential amino acids and other nutrients and biologically active substances. The aim of the work was to study the effect of the concentration of metabolizable energy in the diet on the indicators of growth, tissue gain and the rate of protein retention in pigs. It was found that rationing of compound feed for young pigs with a live weight of 20-40 kg in terms of metabolizable energy, digestible lysine and other essential amino acids, balanced in accordance with the concept of “ideal protein”, made it possible to satisfy their physiological needs for these nutrients. Feeding animals with compound feed containing 13.8 MJ of metabolizable energy and 10 g/kg of digestible lysine provided 621 g of daily live weight gain at minimum feed consumption (1.44 kg/day).
