Abstract
The present invention discloses grain-saving yellow-feathered meat chicken formula feed and a preparation method and a use method thereof. The feed comprises the following components in percentage by mass: corn 40-46%, wheat bran 4-8%, cassava 20-28%, soybean meal 8-12%, corn gluten meal 3-5%, distillers dried grains with solubles (DDGS) 5-10%, rapeseed meal 3-6%, DL-methionine 0.10-0.15%, lysine 0.10-0.15%, stone powder 1.0-1.2%, calcium hydrogen phosphate 1.0-1.2%, common salt 0.30-0.35%, choline chloride 0.1-0.2%, vitamin premix 0.1% and trace element premix 0.2%. The grain-saving yellow-feathered meat chicken formula feed is formed by applying cassava to the feed and thus part of corns is saved. Therefore, the feed resource tension in the feed industry is alleviated and the production cost of feed for yellow-feathered meat chickens is reduced.
Description
Technical field
The present invention relates to a kind of yellow-feather broiler fodder, belong to feed product technical field, refer in particular to a kind of grain-saving type yellow-feather broiler mixed feed and preparation method thereof and using method.
Background technology
China's animal husbandry development is rapid, and livestock and poultry breeding stock and animal products annual production increase year by year, thus also increase year by year the demand of feed.The total output of China's feed has been increased to 1.94 hundred million tons of 2012 by 1.37 hundred million tons in 2008, add 41.6%.By comparison, China's grain yield increasing degree is relatively low, only increases by 11.5% between 2008 ~ 2012 years.Meanwhile, along with the propelling of China's expanding economy and urbanization, the cultivated area of China reduces year by year.The cultivated area of China in 2012 is 18.26 hundred million mu, close to the arable land red line (1,800,000,000 mu) of national regulation in 2007.In a word, the shortage problem of China's feedstuff affects the development of China's animal husbandry always, has become a major challenge that China's animal husbandry Future Development faces.Therefore, on the basis ensureing grain security, new feedstuff or unconventional feed is sought, to save the study hotspot that the bulk raw material such as corn, dregs of beans has been current feed industry and animal husbandry.
On the other hand, cassava, as the perennial shrub of one, is collectively referred to as the large tuber crops in the world three with sweet potato and potato, has the title of " underground granary " and " king of starch ".Cassava is extensively cultivated in the Guangxi of China, Guangdong, Hainan, Yunnan and Fujian and other places.According to Chinese starch industry association statistics, China cassava cultivated area is at about 6,500,000 mu in recent years, and fresh potato total output reaches total output 850 ~ 8,800,000 tons.Cassava is cheap, and the byproduct etc. after the processing of block root, cauline leaf and tapioca all can be developed as feed.Cassava is nutritious, and especially maximum with content of starch, cassava does the starch containing 70%, and majority exists with the form of amylopectin, opaque exquisiteness, and digestibility is high and not easily by mycotoxin contamination.Therefore, cassava may be used for being used as the main energetic such as replacement of corn, wheat feedstuff in animal feed to reduce these feedstuffs situation in short supply.
