Embodiment Construction

[0032] The present invention was implemented in Shandong Xilaili Feed Co., Ltd. from May to October 2018. Before silage, first crush the air-dried corn stalks, and then use the axial flow mill to crush the forage mulberry into 0.5cm particles after harvesting the forage mulberry suitable for cutting. The ratio of forage mulberry and crushed corn stalk is 5:1. Mix and adjust the moisture content of the fermented feed to 60%. The fermentation dose added to each ton of fermented feed mulberry is: 2kg of corn soft white sugar, 2kg of compound lactic acid bacteria, 1.0kg of Bacillus subtilis and 1kg of Enterococcus faecalis. A mixture of corn stalks is mixed. Finally, it is compacted and closed for fermentation. After 2 weeks of anaerobic fermentation and stabilization, it can be mixed with other feeds and fed directly.

[0033] Evaluation of silage mulberry quality: After anaerobic storage for 2 weeks, the feed quality was evaluated, the pH was 3.8, the crude protein was 17.63%,...

Abstract

The invention discloses a method for preparing high-quality pork feed by using feed mulberry. According to the invention, the method comprises the steps of harvesting feed mulberry in a mowing period,conducting smashing directly by a pulverizer to obtain particles of 0.5 cm, adjusting the moisture content of the particles, then uniformly mixing the particles with a special fermentation preparation, conducting compacting and sealing, then conducting anaerobic fresh storage, and after 2 weeks and anaerobic fermentation is stable, mixing the fermented material with other feeds for direct feeding. The stored feed mulberry of the invention overcomes the problem of poor palatability of feed mulberry after silage, improves the palatability of the pig, and increases the feed intake. The technology is simple in preparation, and is less affected by external environmental conditions, and all farms can separately produce the feed mulberry of the invention. The fermented feed mulberry does not require secondary processing, and does not require additional storage steps, thereby solving the problem of feed mulberry storage, achieving annual supply and reducing nutrient loss during storage.

Description

technical field [0001] The invention relates to a method for preparing and producing high-quality pork feed by using feed mulberry, and belongs to the technical field of animal husbandry. Background technique [0002] The feed mulberry is a herbal mulberry cultivated by artificial hybridization, and the crude protein content of the air-dried sample is above 16%. my country's protein resources are insufficient, and more than 85% depend on imports. The price of protein raw materials remains high, which reduces the efficiency of breeding and affects the long-term stable development of the breeding industry. The dry matter of feed mulberry is 7-8t / hm2, the annual output of soybean is 2-3t / hm2, and the output of feed mulberry protein per unit area is higher than that of soybean. In addition, feeding feed mulberry can replace part of the usage of soybean meal, reduce feeding cost and improve production efficiency. In addition, feeding mulberry feed can increase the fat content a...
