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 laying hens, which will affect the eating and absorption of other nutrients of laying hens, thereby reducing the resistance of laying hens to diseases

Abstract

The invention discloses a laying hen feed using Leucaena microphylla as raw material, which comprises the following raw materials: pretreated Leucaena microphylla, corn flour, soybean meal, bone meal, fish meal, calcium hydrogen phosphate, additives and probiotics; The preparation method of laying hen feed comprises the following steps: (1) pretreatment of Leucaena microphylla: chop the young stems and leaves of Leucaena microphylla into small pieces, soak them in warm water, and freeze them in an environment of -20°C quickly , into the fermentation vessel, mixed with extracellular enzymes, and fed with N 2 / C0 2 mixed gas, fermented, dried and dehydrated to constant weight to obtain pretreated Leucaena lobata; (2) pulverizing and granulating; (3) coating treatment; (4) microalgae sedimentation. The invention can improve the palatability of the leguminous forage, and provides a laying hen feed that effectively reduces the feeding cost, has comprehensive nutritional value, good palatability, easy absorption, convenient use and high disease resistance.

Description

【Technical field】 [0001] The invention belongs to the field of feed, and in particular relates to a feed for laying hens using Leucaena microphylla as a raw material and a preparation method thereof. 【Background technique】 [0002] At present, the development and application of laying hen feed at home and abroad mostly use corn, wheat bran, etc. as raw materials. The feed cost is high, and it is extremely grain-intensive. In order to reduce the cost of breeding, some farmers and enterprises use cheap feed such as Tongmu to reduce the cost, but this seriously affects the daily nutritional needs of laying hens, the rate of feed remuneration decreases, and affects the laying hen production rate and production time. and the quality of livestock products. [0003] Leucaena microphylla is a small shrub of the leguminous family, with a plant height of 1.5m to 3m, even-numbered pinnate compound leaves, soft leaves, good palatability, and rich nutrition. The dry matter in the young ...
