Broiler chicken feed for boosting lean meat percentage and improving slaughter performance and preparation method thereof

Abstract

The invention discloses a broiler chicken feed for boosting lean meat percentage and improving slaughter performance and a preparation method thereof. The broiler chicken feed is prepared from the following raw materials (by weight): 500-600 parts of fresh manioc waste, 1.5-2.5 parts of sodium citrate, 45-48 parts of sunflower seed cake, 56-63 parts of peanut meal, 3-4 parts of radish juice, 1-2 parts of cumin powder, 34-37 parts of wheat germ, 13-16 parts of Arctium lappa L. leaves, 47-54 parts of sea-buckthorn residue, 25-27 parts of dried-powder of housefly larvae, 34-36 parts of wheat bran, 23-25 parts of Typha angustifolia L. powder, 13-16 parts of magnolia denudate powder, 23-27 parts of sickle alfalfa, 17-20 parts of morning-glory vines, 0.4-0.5 part of candida utilis, 3-4 parts of dendrobium candidum, 2-3 parts of rhizoma polygonati, 5-7 parts of exocarpium benincasae powder and 1-2 parts of attapulgite. By the use of the feed, growth and development of broiler chicken can be promoted, nutrition absorption can be improved, weight gain rate can be boosted, slaughter performance can be improved, nutritive value and health care value of chicken can be raised, chicken color is pure, meat is fresh and tender, nutrition value is high, and mouthfeel is good.

Description

[0001] technical field [0002] The invention relates to the technical field of animal breeding, in particular to a broiler feed for improving lean meat percentage and slaughter quality and a preparation method thereof. Background technique [0003] Cassava is one of the staple foods in the world. Together with sweet potatoes and potatoes, it is called the world's three largest tuber crops, and its output ranks seventh among food crops. The main planting areas of cassava in my country are Guangxi, Guangdong, Hainan, Yunnan, Fujian and other places, with an annual output of more than 10 million tons of cassava nationwide. At present, cassava is mainly used to produce starch, and there is a large amount of cassava residue after production. The ratio of cassava residue to starch is 1:2 (calculated on dry matter), that is, the annual output of cassava residue is about 300,000 tons. According to chemical composition analysis, the content of non-nitrogen compounds in cassava re...

Problems solved by technology

Although this scheme has certain positive effects, its disadvantages are also very obvious: First, the author did not effectively treat the cassava residues. Since cassava will add a variety of preparations in the process of extracting starch, some preparations will remain in the fresh cassava residues. , if it is directly used without removal, the quality and taste of the final feed product will be greatly reduced, and it will cause harm to the health of the animals; second, the raw materials used in the scheme are relatively simple, resulting in insufficient nutrition of the product obtained after fermentation , which is not very beneficial to the growth and production of animals; the third is the lack of processing and modulation of fresh cassava residues in the plan, resulting in poor nutrition and taste of the final feed product, which is not conducive to the improvement of animal appetite; the fourth is in the plan The lack of modification measures for fresh cassava residues is not conducive to the further improvement of the function and flavor of feed products
