Embodiment 1

[0026] Cut the fresh Reyan No. 4 King Grass to 2 cm, and then dry it to a semi-dry state, with a moisture content of about 70%. Cassava leaves for mixed silage are harvested and cut to 2 cm. According to the ratio of 65% of semi-dry Reyan No. 4 King Grass, 30% of cassava leaves, and 5% of sugarcane molasses, and add lactic acid bacteria preparations according to the ratio of 5mg / kg of the total mass of the above-mentioned raw materials, take the raw materials, and fully mix them uniformly. Silage in plastic barrels, filled and compacted to expel the air, and sealed after completion. Sampling after storage at room temperature for 30 days, the measured pH value is 3.59, ammonium nitrogen content 4.58%, lactic acid content 8.36%, silage quality is better than comparative example 2; neutral detergent fiber content is 46.27%, acid detergent fiber content is 32.31%, The RFV is 123.68%, and the nutritional value is relatively high.

Embodiment 2

[0028] Cut the fresh Reyan No. 4 King Grass to 2 cm, and then dry it to a semi-dry state, with a moisture content of about 70%. Cassava leaves for mixed silage are harvested and cut to 2 cm. According to the ratio of 70% of semi-dry Reyan No. 4 King Grass, 28% of cassava leaves, and 2% of sugarcane molasses, and add lactic acid bacteria preparations according to the ratio of 5mg / kg of the total mass of the above-mentioned raw materials, take the raw materials, and fully mix them uniformly. Silage in plastic barrels, filled and compacted to expel the air, and sealed after completion. After 30 days of storage at room temperature, samples were taken, and 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 50.55%, the acid detergent fiber content was 34.24%, and the RFV was 108.76 %, higher nutritional value.

Embodiment 3

[0030] Cut the fresh Reyan No. 4 King Grass to 2 cm, and then dry it to a semi-dry state, with a moisture content of about 70%. Cassava leaves for mixed silage are harvested and cut to 2 cm. According to the ratio of 75% of semi-dry Reyan No. 4 King Grass, 23% of cassava leaves, and 2% of sugarcane molasses, and add lactic acid bacteria preparations according to the ratio of 5mg / kg of the total mass of the above-mentioned raw materials, take the raw materials, and fully mix them uniformly. Silage in plastic barrels, filled and compacted to expel the air, and sealed after completion. After 30 days of storage at room temperature, samples were taken. The measured pH value was 4.01, the ammonium nitrogen content was 6.43%, the lactic acid content was 5.75%, and the silage quality was good; the neutral detergent fiber content was 54.79%, the acid detergent fiber content was 37.4%, and the RFV was 96.18 %, higher nutritional value.

[0031] To sum up, the water content of Reyan No...

Abstract

The invention discloses silage with mixed Reyan No.4 Chinese sugarcane and cassava leaves and an ensiling method. The silage comprises the following components by weight percent: 65-85% of half-dry Reyan No.4 Chinese sugarcane, 15-30% of cassava leaves, 1-5% of cane molasses and 5mg / kg of a lactic acid bacteria preparation which is added based on the total weight of the raw materials, wherein the Reyan No.4 Chinese sugarcane is the Reyan No.4 Chinese sugarcane with the water content of 65-70%, and the cassava leaves are fresh harvested cassava leaves; the lactic acid bacteria preparation consists of lactobacillus plantarum. According to the invention, the pH value and the content of ammonium nitrogen of the silage are reduced, the content of lactic acid is improved, and the silage quality is obviously improved; the content of proteins of the silage is improved, the content of fiber components is reduced, and the nutritional value of the silage with the Reyan No.4 Chinese sugarcane is improved; the ensiling method is simple and effective to operate and has significance on solving of imbalance of coarse feed resource supply and reasonable utilization of byproducts of economical crops.

Description

technical field [0001] The invention relates to the technical field of feed processing methods, and in particular relates to silage mixed with Reyan No. 4 king grass and cassava leaves 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 Rey...
