Problems solved by technology

[0004] Compared with the common Leucaena, Leucaena microphylla does not contain mimosin toxin, which can reduce the detoxification process steps in the processing and save production cost, but the content of neutral detergent fiber and acid detergent fiber in Leucaena microphylla is relatively high. High, reaching 39.70% and 34.20% respectively, after conventional fermentation treatment, it is still difficult to be completely digested by meat rabbits, resulting in a negative effect on dry matter intake of meat rabbits, affecting the eating of meat rabbits and the absorption of other nutrients , thereby reducing the resistance of meat rabbits to diseases

Abstract

The invention discloses a feed for rabbits using Leucaena microphylla as raw material, which comprises the following raw materials: pretreated Leucaena microfolia, corn flour, wheat bran, soybean meal, bone meal, inorganic salt, vitamins and amino acid additives, carboxymethyl shell polysaccharide solution mixture and probiotics; the preparation method of the rabbit feed comprises the following steps: (1) pretreatment of Leucaena microphylla: chop the tender stems and leaves of Leucaena microphylla into small sections, soak them in warm water, Freeze in an environment of ‑20°C, put it into a fermentation container, control the stacking thickness of Leucaena lobata, mix in extracellular enzymes, and pass in N 2 / C0 2 The mixed gas is fermented at 23-30° C. for 20-35 hours, dried and dehydrated to constant weight to obtain pretreated Leucaena lobata; (2) crushing and granulating; (3) coating treatment. The invention can improve the palatability of leguminous herbage, and provides a rabbit feed which effectively reduces feeding cost, has comprehensive nutritional value, is easy to absorb, and improves disease resistance.

Description

【Technical field】 [0001] The invention belongs to the field of rabbit feed, and in particular relates to a rabbit feed using Leucaena microphylla as a raw material and a preparation method thereof. 【Background technique】 [0002] At present, the development and application of rabbit feed in my country is mainly based on agricultural and sideline crops such as peanut stalks, soybean stalks, and wheat straw. In order to meet the daily nutritional needs of breeding rabbits and commercial rabbits, a large amount of corn, soybean meal, etc. Increasing the protein content in the feed leads to high feed cost and extremely grain consumption, which is contrary to the idea of ​​transforming traditional grain-consuming animal husbandry to modern grain-saving animal husbandry proposed at this stage in our country. Unreasonable feed composition not only seriously affects the rate of feed return, but also affects the reproductive efficiency of breeding rabbits, and affects the slaughter ra...
