The effectiveness of the use of probiotics for wet maize grain preserving

Abstract

The process of processing and storage of high moisture grain is one of the important problems of forage production, especially in the Carpathian region due to its excessive moisture, therefore, due to the intensification of the livestock industry, the conservation of feed is becoming increasingly important. The purpose of the research was to determine the effect of different doses of bacterial preparation KT-L 18/1 (produced by Chernihiv ISMAV NAAS) on the preservation of nutrients and microbiological parameters of maize grain of high humidity in dynamics. The investigation of influence different doses of bacterial preparation KT-L 18/1 on the nutrients and microbiological parameters protection in maize grain with high humidity were realized in the laboratory of animal feed and feed technology (containers with maize grain, treated with different doses of microbial preparation KT-L 18/1, were laid, their chemical composition and microbiological parameters were determined). The control was grain without drying and with the addition of a chemical preservative CAS. During storage of treated maize grain were determined their chemical composition, content of main fermentation acids, and microbiological parameters. It was found that dry matter reduce, an integral feed nutrition indicator, in maize grain samples, treated with KT-L-18/1 and chemical preservative were 1.0 and 1.1% respectively. The lowest number of harmful micromycetes was noted by using the KT-L-18/1 at dose 8 ml/kg. It was found that using of chemical preservative CAS suppresses all investigated microorganisms, including lactic acid bacteria. Probiotic preparation KT-L-18/1 at dose 8 ml/kg wet maize grain provides to nutrients preservation same level like chemical preservative through active development of lactic acid microorganisms. It is advisable for final conclusions to carry out the testing of this preparation during the harvesting of wet ivy corn grain under production conditions and in experiments on animals.
