Technical Field

The invention relates to a moringa oleifera leaf powder additive feed for improving chicken intestinal tracts and a preparation method thereof, belonging to the field of feed processing and production in the livestock breeding industry.

Background

Moringa (Moringa spp.) belongs to Moringaceae (Moringaceae) of the Moringa suborder (Moringaceae), Moringa (Moringa Adans.) belongs to a single plant of a single family, and 13 species in total are present in the family. Moringa oleifera is a miraculous tropical and subtropical multifunctional plant, has a long history of eating, is rich and comprehensive in nutrition, is the best plant protein, vitamin, folic acid, pantothenic acid, calcium, iron, selenium and other nutrient sources found at present, is seriously short in traditional protein feed resources and high in price in China, and becomes a main factor restricting the development of animal husbandry at present, so that a novel protein feed with low price, high yield and high efficiency is sought to completely or partially replace the traditional protein feed to become a hotspot of research of animal nutriologists.

The moringa oleifera has the characteristics of high yield, rich nutrition, wide adaptability, simple and convenient cultivation, strong stress resistance and the like, and has the reputation of 'strange trees' and 'plant diamonds' internationally. In China, Moringa oleifera is introduced to Australian planting in the earliest 19 th century, Hainan island planting is introduced before and after 1940, southwest area is introduced after 1960, and Moringa oleifera introduction and cultivation tests are performed in Yunnan province in the early 60 th of 20 th century. By 2019, the planting area of the moringa oleifera in China exceeds 10 ten thousand mu. In recent years, the moringa industry has been rapidly developed and mainly developed for food and medical health products. At present, no research on the development of moringa oleifera leaves in poultry feed is reported in China.

With the development of economy, the animal husbandry in China faces significant challenges and unprecedented opportunities for development. At present, the feed resources are poor, and concentrated feed, particularly protein feed, is in short supply; more people and less land, more people and less land: the forage grass has unreasonable planting structure, low specific gravity of high-yield and fast-growing high-quality woody fodder, low production efficiency of energy and protein per unit land area, and serious restriction on sustainable development of animal husbandry in China. Among a plurality of factors restricting the development of animal husbandry, accelerating the adjustment of the production structure of forage grass and accelerating the development of high-yield, fast-growing and high-quality woody forage planting are important and urgent.
