Embodiment 1

[0019] A non-protein nitrogen feed additive, consisting of the following raw material components in mass percentage: 65% corn flour, 25% urea, 8% bentonite, 1% sodium diacetate, 1% Bacillus subtilis preparation, wherein Each gram of Bacillus subtilis preparation contains 10 billion live spores. Specifically, it is prepared according to the following steps: each component is weighed according to the mass percentage of the above-mentioned raw material components, and then mixed evenly.

Embodiment 2

[0021] A non-protein nitrogen feed additive, consisting of the following raw material components in mass percentage: 60% corn flour, 30% urea, 5% bentonite, 2% sodium diacetate, 3% Bacillus subtilis preparation, wherein Each gram of Bacillus subtilis preparation contains 20 billion live spores. Specifically, it is prepared according to the following steps: each component is weighed according to the mass percentage of the above-mentioned raw material components, and then mixed evenly.

Embodiment 3

[0023] A non-protein nitrogen feed additive, consisting of the following raw material components in mass percentage: 70% corn flour, 20% urea, 7% bentonite, 2% sodium diacetate, 1% Bacillus subtilis preparation, wherein Each gram of Bacillus subtilis preparation contains 30 billion live spores. Specifically, it is prepared according to the following steps: each component is weighed according to the mass percentage of the above-mentioned raw material components, and then mixed evenly.

[0024] In order to verify the application effect of the non-protein nitrogen feed additive of the present invention, the following uses Example 1 as an experimental group to verify the effect of slow release of ammonia nitrogen and the effect on the growth of dairy cows.

Abstract

The invention discloses a non-protein nitrogen feed additive. The non-protein nitrogen feed additive is prepared from, by mass, 60-70% of corn flour, 20-30% of urea, 5-10% of bentonite, 1-2% of sodium diacetate and 1-3% of a bacillus subtilis preparation, wherein each gram of the bacillus subtilis preparation contains 10-20 billion living spores. The non-protein nitrogen feed additive is low in cost and easy to prepare, can replace expensive protein raw materials like corn and has good application prospects in preparing ruminant feed. The invention further discloses a calf feed prepared from the non-protein nitrogen feed additive. The calf feed is prepared from, by mass, 35-38% of corn, 10-12% of sorghum, 18-20% of wheat bran, 4-6% of bean pulp, 20-22% of cottonseed cakes, 1-2% of mountain flour, 1-1.5% of sodium chloride, 0.5-1% of premix and 4-6% of the non-protein nitrogen feed additive. The calf feed can increase the growth speed of calves and also can significantly reduce the feed production cost.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a non-protein nitrogen feed additive and its application. Background technique [0002] With the improvement of people's living standards, the Engel ratio is becoming more and more reasonable, and the dietary structure is improving day by day. The share of animal husbandry products such as meat, eggs, and milk in people's food is growing rapidly, especially the development of the dairy industry has become an important factor. The most competitive industry in animal husbandry. However, the shortage of land resources in our country, the low grain output, and the gradual increase in the demand for grain in animal husbandry have led to a shortage of feed, especially protein feed. [0003] Non-protein nitrogen (agricultural nitrogen fertilizer, etc.) has great potential for production and has a wide range of sources. It can be produced independently of land and can be...
