Daily ration of the yellow-feather broiler of raising with stocking model and its preparation method and application
Technical field
The present invention relates to field of animal feed, be specifically related to a kind of yellow-feather broiler without daily ration of calcium monohydrogen phosphate and its preparation method and application.
Background technology
Calcium, phosphorus are elements essential in the animal life activity, and in current feed industry, calcium monohydrogen phosphate is main phosphorus source, and calcium monohydrogen phosphate or similar composition are arranged in all feeds, with the content that guarantees phosphorus in finished product feedstuff, can meet the needs of growth of animal.Yellow-feather broiler is the indigenous chicken kind of China, has a growth cycle long, the characteristics that speed of weight increment is slow.At later stages, the feed intake of yellow-feather broiler is large, but speed of weight increment is slow, and the phosphorus level of daily ration is lower than early stage, but due to the research that lacks the accurate requirement of yellow-feather broiler phosphorus, in existing formula, the level of phosphorus has all added very large safety factor.The feeding manner of yellow-feather broiler has stable breeding and puts two kinds in a suitable place to breed, mainly take the pattern of putting in a suitable place to breed as main.What mainly adopt due to yellow-feather broiler is the raising pattern of putting in a suitable place to breed, and broiler chicken can be from obtaining extra supplementing environment.And the calcium monohydrogen phosphate price is high, causes production cost higher, and too much phosphorus can not absorb by animal, after with ight soil, discharging, environment has been caused to pollution.
Phytase, as a kind of enzyme preparation by the microorganism fermenting and producing, can decompose the natural organophosphor in animal feed.The price circle of phytase is lower than calcium monohydrogen phosphate, and is in prior art, open, in feed, adds phytase and can replace the part calcium monohydrogen phosphate, improves the content of non-phytate phosphorus in feed.
No matter use phytase or calcium monohydrogen phosphate, what use, depend on the accurate assurance to the phosphorus requirement of institute's letting animals feed.And the kind difference of animal, growth phase is different, the raising pattern all can not make its difference of requirement to non-phytate phosphorus on an equal basis.
For yellow-feather broiler of the present invention, according to the amount of Chinese fowl raising standard recommendation in 2004, the requirement of the non-phytate phosphorus (NPP) of the yellow-feather broiler in 7 ~ 18 ages in week is 0.36%; Requirement is larger, in order to guarantee non-phytate phosphorus enough in feed, in existing yellow-feather broiler fodder formula, must guarantee that the content of non-phytate phosphorus reaches the level that needs by adding calcium monohydrogen phosphate.Therefore the cost of feed is still higher.
Summary of the invention
The first goal of the invention of the present invention is to overcome the defect of prior art, and the yellow-feather broiler that a kind of production cost is low, environmental pollution is light daily ration is provided.
The second goal of the invention of the present invention is to provide a kind of preparation method of above-mentioned yellow-feather broiler daily ration.
The 3rd goal of the invention of invention is to provide a kind of application of above-mentioned yellow-feather broiler daily ration.
For realizing the first goal of the invention of the present invention, the present invention adopts following technical scheme, and its raw material is comprised of (A), (B) two kinds of components:
Wherein (A) component is comprised of following component by accounting for the calculating of Diet Formula percetage by weight: corn 52-69%, wheat 10-30%, dregs of beans 2-7%, corn protein powder 3-5%, lard 2.5-3%, cotton dregs 2-6%, peanut meal 2-6%, stone flour 0.9-1.1%, lysine 0.5-0.8%, premix 0.6%, salt 0.3-0.4%, threonine 0.1-0.15%, methionine 0.1-0.15%; Above-mentioned A component meets makes nonphytate P level in raw material be at least 0.1%;
(B) component is comprised of the phytase that accounts for Diet Formula weight 0.12 ~ 0.15%.
The inventor finds through the long-term breeding research to yellow-feather broiler, and for the yellow-feather broiler of raising with stocking model, after its 85 day age, in daily ration, nonphytate P level only need to reach the 0.2% normal growth needs that can meet yellow-feather broiler.Therefore, the broiler chicken for after 85 day age of stocking model raising, can keep the non-phytate phosphorus of reduced levels to get final product in its daily ration.
Simultaneously, we find, in daily ration, add 0.12 ~ 0.15% phytase and both can improve the nonphytate P level of formula more than 0.1%.Therefore, the rational proportion of A component in filling a prescription by adjustment, make the A component that 0.1% non-phytate phosphorus is provided at least, then coordinate with the phytase of B component, can meet the nonphytate P level that makes in daily ration and reach 0.2%.Therefore, in Diet Formula of the present invention, without adding calcium monohydrogen phosphate, namely can meet the demand of broiler chicken to phosphorus, and the production performance of chicken is had no adverse effect, carcass quality can not change, and not there will be skeletal diseases.
In described premix, multidimensional and many ore deposits respectively account for 50 % by weight.
For realizing the second goal of the invention of the present invention, the present invention adopts following technical scheme, and a kind of above-mentioned yellow-feather broiler, without the daily ration preparation method of calcium monohydrogen phosphate, is crossed 80 mesh sieves after the above-mentioned raw materials component is pulverized, and then mixes and gets final product.
For realizing the 3rd goal of the invention of the present invention, the present invention adopts following technical scheme, and the application of the daily ration of described yellow-feather broiler of raising with stocking model, is characterized in that, is applied to feeding of yellow-feather broiler after 85 ages in days that stocking model raises.
