Problems solved by technology

[0004] The object of the present invention is to provide a silage additive specially used for Pennisetum silage, which can not only inhibit the growth of aerobic microorganisms in the silage process of Pennisetum silage, shorten the aerobic respiration period of silage, but also promote the growth of Pennisetum lactic acid bacteria. Rapid propagation, overcome the problems of poor adaptability and poor growth performance of adding exogenous lactic acid bacteria to pennisetum silage, thereby significantly improving the effect of fermentation quality of pennisetum silage

Embodiment Construction

[0010] In order to make the content of the present invention easier to understand, the technical solutions of the present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0011] 1. Extraction and purification of Pennisetum lactic acid bacteria: Weigh 5g of vigorously growing and fresh “Minmu No. 6” Pennisetum leaves, cut them into small pieces about 1cm long with scissors, and put them into 50mL MRS liquid medium for 37 Cultivate statically at ℃ for 72 hours, then inoculate 0.5 mL of MRS fermentation broth into 9.5 mL of MRS liquid medium, and culture in anaerobic chamber. After 5 generations of continuous culture, the bacterial solution with a pH value higher than 4.0 was eliminated, and then the subculture was continued, and the bacterial solution with a pH value higher than 4.0 was eliminated at any time. After about 10 generations of subculture, a strain was selected with a low and stabl...

Abstract

The invention discloses a special silage additive for pennisetum alopecuroides. The silage additive contains the following raw materials in percentages by weight: 1.00wt% of a schisandra chinensis extracting solution, 2.00wt% of an astragalus membranaceus extracting solution and 1.00wt% of a honeysuckle extracting solution. The silage additive is capable of inhibiting growth of aerobic microorganisms in pennisetum alopecuroides silage process, shortening the aerobic respiration stage of silage, promoting rapid propagation of lactic acid bacteria of the pennisetum alopecuroides and solving the problems that exogenous lactic acid bacteria is low in adaptability and poor in growth performance in the pennisetum alopecuroides silage, thereby significantly improving the silage fermentation quality of the pennisetum alopecuroides. Through detection, the promoting ratio of the silage additive on lactic acid bacteria of the pennisetum alopecuroides is 16.51%.

Description

technical field [0001] The invention belongs to the technical field of silage, and in particular relates to a silage additive specially used for pennisetum. Background technique [0002] Pennisetum ( Chinese Pennisetum ) is a perennial gramineous forage grass with high yield, mowing resistance and good palatability. It is a high-quality green feed for herbivorous livestock. Due to its strong drought and humidity resistance and low soil requirements, it has been widely promoted and applied in the southern red soil mountainous areas in recent years. The peak production period of Pennisetum is concentrated in summer, and silage of Pennisetum in summer is conducive to the balanced seasonal supply of Pennisetum and the improvement of its utilization efficiency. [0003] Silage fermentation generally includes, aerobic respiration period, lactic acid fermentation period and stable storage period. After silage fermentation, all the biological and chemical processes in Pennisetum ...
