Embodiment 1

[0012] 1.1 Test material

[0013] The alfalfa material was planted in the West Lake Management District of Changde City. It was harvested with a combine harvester on July 5, 2019, and crushed to 1-2 cm at the same time. Corn flour is crushed into powder from corn kernels purchased by the Lifang Grain Purchase and Marketing Department of Baxiantong Town, Naiman Banner. Wheat bran is produced by Handan Ruima Noodle Industry Co., Ltd. Corn dried distiller's grains are produced by Mengzhou Houyuan Biotechnology Co., Ltd. Soybean meal was produced by COFCO Cereals and Oils Industry (Jingzhou) Co., Ltd.

[0014] The nutritional components of various silage raw materials are shown in Table 1.

Embodiment 2

[0055] In order to verify the effect of the alfalfa high-protein silage provided by the application for feeding pigs, 45 pigs in good health were selected, and the feeding test was started 45 days before slaughter. A completely randomized experimental design was adopted, and 45 pigs were randomly divided into 3 groups (n=15), and divided into two experimental groups, control group A and B; Protein silage (80% alfalfa, 10-12.5% ​​soybean meal, 0-2.5% corn meal, 0-2.5% wheat bran, and 2.5-10% corn distiller's grain) replaced 10% of the complete diet. The silage and the full-price ration are mixed according to the ratio, and a small amount of water is added to maintain the fluidity of the feed, and they are fed in the form of liquid feed.

[0056] The group house feeding method is adopted, and the pig house is thoroughly cleaned and disinfected before feeding. After one week of pre-feeding, the formal feeding test was carried out. The test period is 45d.

[0057] The results s...

Embodiment 3

[0059] In order to verify the effect of the alfalfa high-protein silage provided by the application for feeding perinatal sows, 45 perinatal sows in good health were selected to start a feeding experiment. A completely randomized experimental design was adopted, and 45 perinatal sows were randomly divided into 3 groups (n=15), and divided into two experimental groups, control group A and B; Alfalfa high-protein silage (80% alfalfa, 10-12.5% ​​soybean meal, 0-2.5% corn meal, 0-2.5% wheat bran and 2.5-10% corn dry distiller's grain) replaces 20% of the full-price diet . The silage and the full-price ration are mixed according to the ratio, and a small amount of water is added to maintain the fluidity of the feed, and they are fed in the form of liquid feed.

[0060] The group house feeding method is adopted, and the pig house is thoroughly cleaned and disinfected before feeding. After one week of pre-feeding, the formal feeding test was carried out. The test period is the who...

Abstract

The invention discloses a high-protein alfalfa silage, which is composed of alfalfa and a mixture according to the mass ratio of (3-5): 1; the mixture is composed of the following components (by mass)50-65% of soybean meal, 0-15% of corn flour, 0-15% of wheat bran and 12-50% of corn dry total alcohol grains. The high-protein alfalfa silage of the invention has low crude cellulose content (less than 18%), high crude protein content ( greater than 20%) and good silage fermentation quality.

Description

technical field [0001] The invention belongs to the technical field of feed formula, and in particular relates to alfalfa high-protein silage. Background technique [0002] Alfalfa (Medicago sativa L.) is a leguminous perennial high-quality forage grass and an important source of protein roughage for livestock. It is known as the "king of forage grass". Silage is an important method for safe storage of alfalfa under humid climate conditions. The content of lactic acid bacteria in alfalfa is low, the content of soluble carbohydrates is low, and the buffering capacity is high. Conventional silage alone is not easy to succeed. Some studies have shown that silage of alfalfa mixed with other raw materials can improve silage quality. Zhang Ling conducted mixed silage research on defective jujube powder and alfalfa. The results showed that the addition of defective jujube powder improved the fermentation and nutritional quality of silage, increased the number of lactic acid bacter...
