Method for preparing livestock feed by anaerobic fermentation of a complex of purple grasses

Abstract

The application discloses a kind of purple pasture's composite bacteria anaerobic fermentation preparation method of livestock and poultry feed, belong to livestock and poultry green feed preparation technical field.The present application aims at solving the problems of poor specificity of existing pasture fermentation technology, large fluctuation of fermentation period, and the problem that the nutritional and biological activity advantages of purple pasture cannot be fully utilized.The fresh purple pasture is adjusted to the appropriate moisture content after pretreatment, inoculated with self-prepared multi-strain synergistic composite bacteria suspension, and then anaerobic fermentation is carried out after adding an appropriate amount of nutritional adjuvant, compacting and sealing.The fermentation time is controlled according to the environmental temperature of different seasons, and the finished product is obtained after natural airing and crushing after fermentation.The present application significantly improves the crude protein content of feed and reduces the crude fiber content through the synergistic effect of multi-strains, and the fermentation period is stable and controllable.The feed is palatable and rich in probiotics, which can effectively improve the growth performance of livestock and poultry, reduce the diarrhea rate, and has simple process and low cost, suitable for large-scale popularization and application.
