Актуальность. Моноглицериды органических кислот рассматриваются как перспективная замена кормовых антибиотиков в рационах свиней и птиц, так какони обладают выраженными бактериостатическими и бактерицидными свойствами. Одним из самых перспективных соединений является альфа-монолаурин, обладающий значительным антибактериальным действием на грамположительные микроорганизмы.

Методы

Методы. Опыт проведен на одном из свинокомплексов Ростовской области 5–27 сентября 2020 г. на свиньях на откорме весом от 36 кг и до достижения живой массы в 75 кг. Поросята опытной группы в составе премикса для комбикорма марки СК-5 получали 0,4 кг/т альфа-монолаурина. В условиях производственной площадки проводились контрольные взвешивания перед началом и по завершении опыта. Фиксировали показатели прироста живой массы за период опыта, потребление корма, сохранность, конверсию корма.

Результаты

Результаты. Изучена возможность применения альфа-моноглицерида лауриновой кислоты (GML, глицерол монолаурат) в рационе свиней первого периода откорма в условиях действующего свинокомплекса. Установлено, что альфа-монолаурин улучшает конверсию корма, снижает потребление корма, а также увеличивает сохранность свиней на откорме. Применение альфа-монолаурина привело к увеличению экономической эффективности выращивания свиней на 37,63 руб./гол., или на каждый вложенный рубль было получено 2,38 рубля прибыли.

Relevance

Relevance. Monoglycerides of organic acids are considered as a promising replacement for feed antibiotics in the diets of pigs and poultry, as they have pronounced bacteriostatic and bactericidal properties. Alpha-monolaurin is a one of the most promising compound, which has a significant antibacterial effect on gram-positive microorganisms.

Methods

Methods. The experiment was carried out at one of the pig farms of the Rostov region on September 5–27, 2020 on fattening pigs weighing from 36 kg and up to achievinga live weight of 75 kg. Piglets of the experimental group received 0.4 kg/t of alpha-monolaurin as part of the premix for compound feed CK-5. In the conditions of the production site, control weighing was carried out before the beginning and at the end of the experiment. Weight gain, feed consumption, survival rate and feed conversion were recorded.

Results

Results. The possibility of using alpha-monoglyceride lauric acid (GML, glycerol monolaurate) in the ration of pigs of the first period of fattening under the industrial conditions of an operating pig farm has been studied. It has been found that alphamonolaurin improves feed conversion, reduces feed intake, and also increases the survival rate of fattening pigs. The use of alpha-monolaurin led to an increase in the economic efficiency of raising pigs by 37.63 rubles/head, or 1:2.38 ROI.
