Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a kind of silage mixed with Reyan No. 4 king grass and papaya peel and its silage method, which solves the problem that Reyan No. 4 king grass is used as silage raw material, and the silage quality is low and the fiber content is high. The problem of low nutritional value; on the other hand, by adding papaya peel, the content of soluble sugar is increased

Embodiment 1

[0023] Cut the fresh Reyan No. 4 king grass to 2-3 cm, and then dry it to a semi-dry state, with a moisture content of about 70%. The papaya skins for mixed silage are prepared 24 hours in advance by reducing the moisture content to 30% and removing rotting parts. Mix evenly according to the ratio of semi-dry Reyan No. 4 Wangcao 85% and papaya peel 15%, use plastic barrels for silage, fill and compact to discharge air, and seal after completion. Sampling after normal temperature storage for 30 days, the measured pH value is 4.13, ammonium nitrogen content 8.52%, lactic acid content 5.03%, silage quality is better than embodiment 2; neutral detergent fiber content is 56.79%, acid detergent fiber content is 41.40%, The RFV is 92.79%, and the nutritional value has improved.

Embodiment 2

[0025] Cut the fresh Reyan No. 4 king grass to 2-3 cm, and then dry it to a semi-dry state, with a moisture content of about 70%. The papaya skins for mixed silage are prepared 24 hours in advance by reducing the moisture content to 30% and removing rotting parts. Mix evenly according to the ratio of 75% of semi-dry Reyan No. 4 Wangcao and 25% of papaya peel, use plastic barrels for silage, fill and compact to discharge air, and seal after completion. After 30 days of storage at room temperature, samples were taken. The measured pH value was 3.87, the ammonium nitrogen content was 5.80%, the lactic acid content was 6.90%, and the silage quality was good; the neutral detergent fiber content was 53.00%, the acid detergent fiber content was 38.78%, and the RFV was 99.96 %, higher nutritional value.

Embodiment 3

[0027] Cut the fresh Reyan No. 4 king grass to 2-3 cm, and then dry it to a semi-dry state, with a moisture content of about 70%. The papaya skins for mixed silage are prepared 24 hours in advance by reducing the moisture content to 30% and removing rotting parts. Mix evenly according to the ratio of 65% of semi-dry Reyan No. 4 king grass and 35% of papaya peel, use plastic barrels for silage, fill and compact to discharge air, and seal after completion. After 30 days of storage at room temperature, samples were taken. It was determined that the pH value was 3.71, the ammonium nitrogen content was 5.33%, the lactic acid content was 7.57%, and the silage quality was good; the neutral detergent fiber content was 49.44%, the acid detergent fiber content was 35.15%, and the RFV was 115.70 %, higher nutritional value.

[0028] In summary, reducing the water content of Reyan No. 4 King Grass by drying, adding papaya peel to supplement soluble sugar in the silage fermentation substr...

Abstract

The invention discloses a King grass and papaya skin mixed silage which is characterized by comprising the following components in percentage by weight: 65-85 percent of damp-dry King grass and 15-35 percent of papaya skin, wherein the water content of the damp-dry King grass is 70 percent, and the water content of the papaya skin is 30 percent. The water content of the damp-dry King grass is reduced through drying treatment, and the papaya skin is added so as to supplement soluble sugar of an ensiling fermentation substrate, so that the King grass ensiling is easy to succeed. Through the treatment, the pH value and the ammonium nitrogen content of the silage are reduced, the lactic acid content is increased, and the ensiling quality is significantly improved. The fiber content is reduced, the nutritive value of the King grass silage is improved, and the operation is simple and effective. The silage has important significances for achieving the purposes of balance of coarse fodder resource supply, reasonable utilization of industrial by-products, and improvement of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of feed processing methods, and in particular to a silage mixed with Reyan No. 4 king grass and papaya peel and a silage method thereof. Background technique [0002] Reyan 4 Wangcao is a high-quality perennial grass forage bred by the Institute of Tropical Crops Variety Resources of the Chinese Academy of Tropical Agricultural Sciences. It has the characteristics of high yield and good palatability, and is an important source of roughage for ruminant livestock in tropical areas. In Hainan, there is little rain in winter and spring, the temperature is low, and the growth of plants is slow, causing a shortage of forage grass. Therefore, during the vigorous growth season of Reyan No. 4 kinggrass, it is of great significance to balance the annual feed supply of livestock and promote animal production performance by ensiling excess green grass in an appropriate way. However, the moisture content of Reyan No. 4 ...
