It is given the results of researches conducted under conditions of the industrial pig breeding farms of Sumy Meat Company on 72 pigs of the Large White breed. The control group of piglets used a stationary bunker self-feeder with a round trough, and the experimental one was an experimental one that was different from that of a hollow cylinder in the lower part of which a compartment for an adsorbent or flavor is located, closed with a perforated circular plate with a cylindrical protrusion, and in the middle – fodder cells with the size of sufficient to promote the pig's head, and in the upper – the lid. Moreover, the size of the perforations is made to prevent spill aging into the compartment of the feed additive. It was determined that the consumption of feed by pigs in the experimental group compared with the control on the 14th, 21st, 28th days of the suckling period was significantly higher for 24.0, 70.2 and 99.7 grams per litter per day.
Observations carried out during the experiment showed that the proposed the construction of self-feeder prevents the excrement, the deterioration of feed, activates the pig activity and promotes the increase of their live weight by 17.9%.
