NEW METHODS OF MANURE DISPOSAL AND USE OF PROCESSING PRODUCTS IN PIG BREEDING

The research was conducted in the laboratory of innovative technologies and experimental facilities of Institute of Pig Breeding and AIP NAAS and in the conditions of LIGA COJIAP LLC. In the course of the research, they evaluated and improved the “stepping technology” of vermiculture, developed a method of extracting young dungworms from compost, determined the possibility of vermiculture in large-sized packages of the “Big-Bag” type, and the expediency of using vermighumus and “Nanoverm” in the rations of young pigs. Vermihumus was obtained by utilizing manure in a continuous reactor to obtain vermiproduction using California worms (Eisenia Foetida). Raw vermighumus was extracted in the ABC-100 vortex bed apparatus and the biological preparation “Nanoverm” was obtained. It is determined that the technology has been developed vermiculture in containers compared to that in the fields in open ground increases the output of vermiculture by 14.78% and vermihumus by 23.36%. The developed method of extracting young worms from compost, compared to the known one, ensures the separation of young individuals from sexually mature ones from compost. allows to separate young individuals from sexually mature ones. For the effective disposal of manure as a biological reactor for the production of compost and vermiproduction, a large-sized package “Big-Bag” was used, as well as a thermal case, which is four horizontally stacked reconstructed used truck ramps, covered with a polyurethane cover, in the middle of which a thermostat and a two-meter heating cable are installed. The developed device provided air temperature in the zone of vital activity of worms in the cold period of the year within the range of 13-18ºC. Before feeding, raw vermighumus was mixed with compound feed and placed in the feeder, and “Nanoverm” – in a trough with water. For weaned piglets, the dose of vermighumus was 80-120 g per head per day at the age of 28-45 days, and Nanoverm – 2 ml, for 46-60 days 2.5 ml, 61-75 days – 3 ml. It was determined that the introduction of vermighumus and “Nanoverm” into the diet of weaned piglets had a positive effect on their growth energy and survival. In terms of live weight, the piglets outnumbered the control analogues at the age of 60 days by 13, 11 and 6.96%, and at the age of 90 days – by 14.2 and 11.52%, respectively. The cost of additional main products obtained from feeding vermihumus and “Nanoverm” to piglets was UAH 343.3/head in the first experimental group, and UAH 278.53/head in the second.
