Проблема разработки эффективных жировых добавок для молодняка современных высокопродуктивных пород и линий свиней осложняется трудностями изучения механизмов физико-химических трансформаций липидных комплексов, которые происходят в просвете кишечника и в процессе их всасывания. Решение проблемы осложнятся наличием широкого спектра различий по составу и качеству в источниках жировых добавок для свиней. В связи с этим возникает необходимость в более глубоком изучении влияния химического состава липидов на их переваривание и метаболизм. Результаты изучения физиологических механизмов этих процессов и роли факторов, влияющих на усвоение жировых добавок, позволяют разработать способы повышения эффективности использования липидов. Основные разделы обзора: общая классификация липидов; переваривание и усвоение липидов; питательная ценность жиров и масел в рационах свиней; жирные кислоты в питании свиней; влияние уровня окисленности жиров и масел на их усвоение. Более тщательная оценка факторов, влияющих на физиологические эффекты липидных добавок в рационах свиней, требуется в связи с современными достижениями в области исследования процессов переваривания липидов, их метаболизма после всасывания, процессов клеточного деления, иммунной функции и метаболического стресса у продуктивных животных. В целом, для разработки эффективных жировых добавок и их применения в свиноводстве необходимо проведение дальнейших исследований по изучению физико-химических свойств липидных комплексов и физиологических эффектов их действия в просвете кишечника, в процессах всасывания и метаболизма.
