Abstract
The article presents the results of experiments on studying the preservative effect of various additives in the production of snaplage from early-ripening corn hybrids in the conditions of the Central region of the Russian Federation. After opening the containers with feed, its quality indicators were assessed by the content and ratio of organic acids, the degree of acidification, the content of ammonia nitrogen, the preservation of sugars and essential nutrients. In physiological experiments on Romanov wethers, the digestibility of nutrients was determined. It was found that in all variants, the acidity of the feed was optimal (pH 4.2 and below), which excluded the development of undesirable microbiota. At the same time, in the snaplage with chemical preservatives, acidification occurred due to formic and propionic acids introduced with the preparations and (partially) due to the fermentation of sugars. The results of the physiological experiment showed that the digestibility of dry matter of snaplage from the early-ripening hybrid corn Emelin was high (over 70.2%) in all variants, which also affected the energy value (over 11 MJ NE). Thus, for high-moisture snaplage from early-ripening corn hybrids in the Central region of Russia, it is possible to use both chemical preservatives based on organic acids and biological inoculants intended for the preservation of wet flattened grain, containing active strains of lactic acid bacteria.
