PROMISING METHODS OF MANURE UTILIZATION AND USE OF VERMOPRODUCTS IN PIG FARMING

Abstract

A study was conducted to determine the methods of manure utilization and the use of vermicompost in pig farming. The study was conducted in the conditions of LLC "LIGA COJIAP", Zaporizhzhia region and LLC "Agroprime Holding" Odessa region. The characteristics of various operations and processes (preparation, structure and mass of the population, monitoring of population development, extraction of worms, collection of vermicompost and its repackaging) are given. (substrate preparation, vermiculture settlement, worm adaptation, nutrient substrate consumption rate, settlement density, population structure and mass, population development monitoring, worm extraction, vermicompost collection and its repackaging), which characterized a particular vermiculture technology. It was found that the production of vermihumus and vermiculture (California worms), depends on the vermiculture technology. It has been established that for manure utilization it is advisable to use modern vermicomposting technologies, namely in continuous vermireactors. In particular, when using vermicomposting technology in continuous reactors compared to "stationary banks", the production of vermihumus per 1 m2 increases by 2.70 times, and vermiculture by 2.68 times, the cost of vermicompost is reduced by 2.24 times, and vermiculture by 2.6 times, and the level of profitability increases by 2.22 and 2.6 times, respectively. It has been established that the technology of vermicomposting in continuous reactors makes it possible to increase production volumes, reduce physical labor costs and reduce the cost of vermiproduction.
It has been proven that the introduction of 5 and 10% of dry vermihumus contributes to an increase in the average daily gain in live weight by 7.92 and 15.29%, respectively, and in live weight by 4.02 and 8.76%.
