ДИНАМИКА ИЗМЕНЕНИЯ ПИТАТЕЛЬНОСТИ СЕНАЖА ЛЮЦЕРНОВОГО ПО СРОКАМ ХРАНЕНИЯ ПРИ ПРИМЕНЕНИИ РАЗЛИЧНЫХ БИОЛОГИЧЕСКИХ КОНСЕРВАНТОВ

Abstract

Scientists of Tatar Scientific Research Institute of Agriculture, FRC Kazan Scientific Center, Russian Academy of Sciences and JSC Bioamid (Saratov, Russia) in creative collaboration developed experimental samples of the biological preservative Bioamid-3 with different concentrations and ratios of lactic acid bacteria, without and in combination with enzymes. Studies of the chemical composition and nutritional value of alfalfa haylage, on a daily basis for 3, 6, 10, 17, 30 days of storage, were carried out with the aim of assessing the effectiveness of preservation of experimental preparations in comparison with other industrial biological preparations Sil-All 4x4, Bioamide-3 and without preservative (the control). In the course of laboratory analyzes, it was found that on the 30th day of storage, the dry matter safety was higher in haylages using Bioamide-3 C-0, Bioamid-3 С-0,5, respectively, 1,1 (p≤0,05), 0,9% than in the control sample. In terms of crude protein, superiority was noted in samples with Bioamide-3 C 0,25% (p≤0,05), Sil-All 4x4 0,16%, Bioamid-3 C-0 by 0,11% with respect to control. The greatest increase in crude fiber concentration was found in haylages with preservatives Bioamid-3 C-0, Bioamide-3 C-0,5, Bioamid-3 C - by 0,28% (p≤0,05), 0,20, 0,20% in comparison with the control. The maximum level of metabolic energy was also revealed in the variants with the use of new drugs in excess of the control level for Bioamid-3 С-0 at 4,55% (p≤0,05), Bioamid-3 C-0,5 – 3,18% (p≤0,05), Bioamid-3 C – 1,82%.
