A Ganoderma lucidum polysaccharide preparation that regulates rumen microflora

Abstract

The invention discloses a ganoderma polysaccharide preparation for regulating rumen microflora and a preparation method thereof. The invention extracts the ganoderma polysaccharide from ganoderma ganoderma residues, ganoderma processing leftovers or ganoderma, and adds a carrier to make a preparation. The preparation is added to the premix or total mixed ration at 5-50 mg / kg dry matter of the ration, and is used to feed cattle and sheep. Filamentous bacteria, Ruminococcus xanthus, Bacillus fibrinolyticus and total bacteria concentration, reduce the concentration of methane bacteria, increase the production of NH3-N, microbial protein and total volatile fatty acids, and at the same time enhance the immunity of cattle and sheep, and improve fiber feed Utilization, improve production performance. Moreover, the source is easy, the preparation process is simple, the use is convenient and safe, and there is no side effect. It can be used as a green additive for cattle and sheep feed, and has broad application prospects.

Description

technical field

[0001] The invention belongs to the field of feed additive preparation in animal husbandry, and in particular relates to a ganoderma polysaccharide preparation for regulating rumen microflora and a preparation method thereof. Background technique

[0002] Ganoderma lucidum (Ganoderma Lucidum) is also known as red lucidum, red lucidum, wood ganoderma, fungus ganoderma, ten thousand years mushroom, ganoderma grass. With the continuous development of the Ganoderma lucidum industry, the cultivated Ganoderma lucidum lees and other by-products are also increasing year by year. Ganoderma lucidum lees and other by-products contain a large amount of polysaccharides with good biological activity. According to reports, Ganoderma lucidum polysaccharides can directly or indirectly activate immune cells such as T cells, B cells, and macrophages, and promote the proliferation of unpurified splenocytes in vitro; it can enhance humoral and cellular immune responses; Ganoder...
