Abstract
The invention discloses a method for producing a fermented feed for a ruminant by taking a sugarcane waste material as a raw material, and belongs to the technical field of straw ammoniation feed production. In the method, the sugarcane waste material is used as the raw material, and the straw ammoniation feed is prepared by ammoniation and fermentation. The technology is simple, the production cost is low, and limitation on the weather and the season is avoided; a product can be stored for a long time and is easy to popularize; local rich sugarcane resources can be fully used, waste of the sugarcane waste material is reduced, and the utilization rate of the sugarcane waste material is increased; the feed produced by ammoniation fermentation is soft and juicy, smells sweet, sour and fragrant, is high in palatability and can promote secretion of the digestive gland; a good effect of increasing the digestion rate of the feed is achieved; a feeding test shows that the feed palatability is obviously improved; the feed intake of cows is increased by 18-23 percent; the digestion rate of organic matters such as cellulose and hemicellulose is increased to 15 percent or so; meanwhile, the feed is high in nutritional value and high in absorption speed; and the daily gain of finished cattle is increased by 3-5 percent, and material-to-meat ratio is reduced by 6-10 percent.
Description
Technical field
The invention belongs to straw ammoniation Feed Production Technology field, be specifically related to a kind of with the method for sugarcane dead meal for raw material ammonification production ruminant fermented feed.
Background technology
Along with the fast development of China's economy, improving constantly of people's living standard, the diet structure of people is also progressively changing, and the shared ratio that obtains of meat, egg, milk is in continuous increase.Greatly developing animal husbandry is the unique channel effectively solving China's livestock products imbalance between supply and demand, and so rely on grain to increase substantially and support that the material conditions of animal husbandry high speed development have not existed, animal husbandry development faces the severe challenge of feed grain shortage.Therefore optimize Feed Manufacturing structure, set up low consumption, efficient Animal husbandry production system is following developing direction.Agriculture district of China about has about 700,000,000 tons stalk resources not obtain fully effective utilization at present every year, and according to measuring and calculating, the feed conversion of 100,000,000 tons of ammoniated straws is worth and is equivalent to 2,500,000 tons of concentrated feeds.Therefore, stalk is used for developing animal husbandry, and has great economic benefit and social effect.
Stalk is crops straw remaining after comprising the harvesting such as corn, wheat, paddy rice, Chinese sorghum, is characterized in that crude fiber content is high, general crude fiber content at 30-50%, have even up to more than 60%, also comprise hemicellulose and lignin etc.Animal is to the digestion of fibrous substance in feed mainly by fermentable in digest tube, and therefore, the roughages such as stalk are only suitable for feeding the ruminants such as cattle and sheep, but its palatability is poor, organic digestibility is low, and poultry feed intake is limited, and particularly lignin is non-digestible.
Fodder process for producing feed is carried out to stalk, cattle and sheep palatability, feed intake and grazing speed can be improved.At present, more straw feed treatment technology is used to have the method such as ensiling, ammonification, expanded, hot spray, fermentable.Stalk after ammoniated treatment, its lignocellulosic is destructurized, and lignin and hemicellulose level reduce, and are beneficial to microbial degradation cellulose, then through microbe fermentation method process, effectively can improve the crude protein content of straw feed, reduce crude fiber content.Ammoniated straw feed quality through fermentable process can reach the standard of grain feed, even better, is effective application of straw feed technology, reaches the object improving straw feed quality.
Summary of the invention
The object of the present invention is to provide a kind of with sugarcane dead meal for the method for straw ammoniation feed prepared by raw material, the method technique is simple, production cost is low, be easy to promote, products obtained therefrom good palatability, be of high nutritive value, absorb fast, long shelf-life and containing a large amount of probio, be suitable for ruminant feeding.
The present invention be achieved in that a kind of with sugarcane dead meal for the method for straw ammoniation feed prepared by raw material, described sugarcane dead meal comprises bagasse, the sugarcane tip and sugarcane leaf, and the method comprises the following steps:
(1) by air-dry to bagasse, the sugarcane tip and sugarcane leaf or dry, then bagasse, sugarcane tip hand hay cutter are as short as less than 1.5 centimetres, sugarcane leaf hand hay cutter is as short as 2-4 centimetre, and bagasse, the sugarcane tip and sugarcane leaf after mixing hand hay cutter is short, obtain sugarcane dead meal compound;
(2) sugarcane dead meal compound is put into ammonification pond, add the ammoniacal liquor of sugarcane dead meal compound weight 10-15%, the lime of 1-3% and the salt of 0.2-0.8%, keep the water content of ammonification compound (i.e. the compound of sugarcane dead meal compound and ammoniacal liquor, lime, salt) to reach 50-60%; Sealing, under 25-35 DEG C of condition, ammonification 6-12 days, obtains ammoniated straw;
(3) ammoniated straw is taken out, natural air drying; Add the fermenting agent of the wheat bran of ammoniated straw weight 5-10%, the urea of 1.5-3%, 0.5-1.5% magnesium sulfate, 0.5-1.5% ammonium dihydrogen phosphate (ADP) and 5-20%, the water content of fermentation compound (i.e. the compound of ammoniated straw and wheat bran, urea, magnesium sulfate, ammonium dihydrogen phosphate (ADP), fermenting agent) is kept to reach 55-70%, adjust ph is 4.5-7.5, at 25-50 DEG C of condition bottom fermentation 10-15 days, obtain straw ammoniation feed.
Sugarcane, saccharum, perennial tall and big solid draft.The sturdy prosperity of root-like stock.Stalk height 3-5 rice.The southern torrid areas such as TaiWan, China, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan are extensively planted.Sugarcane is temperate zone and tropical crops, is the raw material manufacturing sucrose, and can refines ethanol as energy substitution product.The sugarcane tip, sugarcane leaf, bagasse chaff, blackstrap or alcohol effluent can be used as the feed of the ruminant such as ox, sheep; Molasses, filter mud are mixed in grain fodder and be can be made into pellet; The waste residue of sugar refinery discharge, waste liquid can make again the fertilizer of sugarcane.
Further illustrate as of the present invention, described fermenting agent is by the fermented bacterium of following Feed Manufacturing: candida utili (candidautilis), candida tropicalis (Candidatropicalis), Humicola insolens (Humicolainsolens), long handle wood mould (Trichodermalongibrachiatum), geotrichum candidum (GeotrichumcandidumLink), aspergillus niger (Aspergillusniger), cultivate through expanding, the combination liquid bacterial agent be mixed.
