Description
Technical field
The present invention relates to a kind of feed that improves meat chicken production performance, simultaneously, the invention still further relates to a kind of method of producing the feed that improves meat chicken production performance.
Background technology
Along with the raising and the Developing of Animal Industry of people's living standard, increasing to the demand of animal protein, quality requirements is also more and more higher, and this has just promoted the development of aquaculture and feed industry.And along with the fast development of feed industry and animal husbandry, the feed resource shortage problem also becomes the key factor of restriction animal husbandry development day by day.According to statistics, global poultry (fryer and turkey) output in 1999 if calculate according to feed conversion rate 1.8, then needs high nutrition fowl expect 6,800 ten thousand tons up to 3,800 ten thousand tons every year, is about 12% of world's whole year production feed.China 1999 poultry production (comprising aquatic bird) just reaches 1,230 ten thousand tons, 9 kilograms per capita, also with different speed increments, it is predicted in recent years: from 2000 to the year two thousand twenty, China's energy feed breach will rise to (24-83) * 10
6Ton, and the protein feed resources breach will rise to (24-48) * 10
6Ton, therefore, it is quite difficult that the needs that only depend on limited arable land to satisfy human and livestock and poultry have become, and the contradiction of " people and animals strive grain " is more and more serious.Be the shortage of resource on the one hand, but then, the feed nutrient utilization rate is low, and environmental pollution is serious, has caused the waste of resource.Have report to show that animal has only 15%-20% with the efficient that feed nutrient is converted into livestock products, the nutrient of eating of 80%-85% enters environment, and soil, air and water source have been caused huge pollution, and is especially serious with the pollution of nitrogen, phosphorus.
Just can find that from current protein feeds utilization the protein utilization efficient in the protein feeds is not high, the protein waste is more serious, and the protein utilization efficient in the particularly unconventional protein feeds is lower, and the space of exploiting potentialities is arranged greatly.So-called unconventional feed is meant the general no feed of tradition breed, particularly unconventional protein feeds, ubiquity ANFs in various degree, animal dislikes searching for food or not eating, this feed even searched for food, digestion, utilization ratio is also much lower than traditional protein feeds dregs of beans, fish meal etc.Along with the breed level improves constantly, the demand of protein feeds is increasing, and traditional protein feeds obviously can not be satisfied the demand, and protein feeds has become the limiting factor of the further raising animal level of production.Solve protein feed resource in short supply is forage science research and the problem of raising the practice concern always.Up to the present, mixed feed is produced the situation that ubiquity still the not only in short supply but also waste of protein feeds, and relatively more typical performance is the level that the mixed feed energy does not reach standard code, the be above standard level of regulation of protein content, cause low energy high protein, waste albumen.Some commodity batches are produced, and for outstanding high-quality, propagate as bright spot improving protein content, in fact waste albumen.The low-cost feed that some utilize unconventional protein feed such as rapeseed dregs, the cottonseed dregs of rice etc. to produce, because the low-quality inefficiency problem of raw material itself does not solve, its feeding effect is also bad, particularly this low-cost feed, palatability is generally bad, animal feed intake is low, and production performance is lower, and feeding period increases, caused protein serious waste, obviously, after unconventional protein feeds has solved utilizability in theory, further need to solve the low-quality poor efficiency and utilize problem.Undergoing an unusual development rapidly of present feed processing technology, ultramicro grinding is a very fast new and high technology of development in recent years, uses this technology and solid matter can be crushed to micron even nanoscale.Be widely used among the every field at present, this technology comprises contents such as the ultramicro grinding to powder material, high-precision classification and surface-active change, according to the size or the granularity of raw material and finished particle, pulverizing can be divided into coarse crushing, fine powder is broken, micro mist is broken and ultramicro grinding.Much studies show that the broken protein solubility and the digestibility that can improve raw material significantly of micro mist,, can improve the mouthfeel and the absorbability of fiber significantly by micronize to fiber.
In the exploitation of feed resource, improve the research of food utilization efficiency, generally be in the compound feed prescription design, solve by the amino acid whose method of balance, but the feed formula design on producing at present, generally all balance lysine and methionine, what the amino acid waste was maximum in the feed is leucine, phenylalanine+tyrosine and arginine, these amino acid on average exceed more than 3 times of needs in general feed formula design, be equivalent to waste the crude protein about 4%; On the other hand, though in prescription with the feed balance of separate sources amino acid because the source is different, protein digestibility utilization ratio difference, the amino acid whose actual effect of balance is also very undesirable.
