Silage feed

a fresh feed made by using crop straw, green fertilizer, etc. to inhibit corrupt bacteria by fermentation of lactic acid. It can improve the tasteability, increase bacterial protein and
vitamin
, is a low-cost, simple feed processing preservation method. There are many raw materials used for silage, such as bean straw, sorghum, sunflowers, oats, broad beans, dates, clover, red pings and so on. The above raw materials into tall towers, cellars or other sealable containers, layer by layer, the use of natural breathing to deplete internal oxygen, resulting in anaerobic environment, promote lactic acid fermentation, silage fermentation process can generally be divided into
3
period: the beginning of the preparatory fermentation period. This phase is suitable for a variety of
microbial
growth, first of all E. coli,
yeast
bacteria, corrupt bacteria and some mold, such as a large number of growth,
1
to
2
days to exhaust the oxygen in the material gap. At this time, lactic acid bacteria activity increased, gradually inhibited the growth of the above bacteria. The
2
period is the mature period, lactic acid bacteria multiply in large numbers, the use of sugar for lactic acid fermentation, the accumulation of lactic acid. Finally, the completion period. At this time, the acid content of silage feed can reach
1
to
2
%,
pH
fell below
4.2
, completely inhibited the growth of other bacteria. Excellent silage feed can be kept for
7
years without any quality. Silage feed is of great significance to the development and improvement of animal husbandry feed and the development of animal husbandry production.
