Abstract
The invention discloses a feed for SPF chicken in the laying starting period, and relates to the technical field of poultry feeds, for solving the problem of nutrition requirements of SPF chicken in the laying starting period. The feed for SPF chicken in the laying starting period comprises the following components in percent by mass: 63.78 percent of corn, 15 percent of 43% ordinary bean pulp, 3.6 percent of 55% corn gluten meal, 9.85 percent of DDGS26 protein, 2 percent of stone grains, 3.2 percent of refined stone powder, 1 percent of calcium hydrophosphate, 0.36 percent of salt, 0.05 percent of 60% choline chloride, 0.58 percent of 65% lysine, 0.17 percent of methionine, 0.01 percent of threonine, 0.2 percent of mineral premix M-P for poultry, 0.1 percent of medium chicken multi-vitamin LV52H, and 0.1 percent of grown chicken multi-vitamin LV62H. Compared with the prior art, the feed for SPF chicken in the laying starting period has remarkable advantages that the survival rate of the chicken groups in the laying starting period is increased by 2.35 percent, and the uniformity is 98.4 percent.
Description
Technical field
The present invention relates to bird feed technical field, be specifically related to a kind of SPF chicken and open feed in term.
Background technology
At present, there is no in the world general SPF fowl raising standard, only have the normative reference of common chicken.SPF chicken is conventionally raised in barrier system or shielding system, from young bird to laying eggs until eliminate, lives in throughout one's life in the environment being hedged off from the outer world, and during chicken all living creatures is long, required all complete by artificial condition.Therefore, the height of the long what state of chicken all living creatures, production performance depends on whether feed nutrition can meet the nutritional requirement of SPF chicken group in each stage to a great extent.Different phase trophic level differs.Therefore, answer combining environmental factor, the situations such as impact of biological characteristics, nutritional need and the feed sterilization that takes into full account SPF chicken on nutrition is actual in conjunction with producing, the required feed of the different growth phases of SPF chicken is studied, required to meet SPF chicken production performance in growth period.The living environment of SPF chicken and requirement are different from common laying hen, thus at its trophic level, formulate and Feeding Prescription Design all will take into full account the difference of SPF chicken and common chicken, therefore when designing feed formula, to take into full account following some:
1) when Feeding Prescription Design, in common chicken feed, allow to add animal protein, fish meal and antibiotic and anti parasitic class medicine, and in SPF chicken feed, forbid adding animal protein, fish meal and antibiotic and anti parasitic class medicine.
2) compare with common chicken, because SPF chicken is all the time in barrier system or isolator, living environment is relatively stable, and (it is 14 ℃～28 ℃ that barrier system requires temperature, and its required metabolizable energy is a little less than the chicken of raising under conventional environment.
3), for to guarantee that SPF chicken has higher production performance, during its formula Design, methionine and lysine outline are high.
4) what the infringement of autoclaving feed was maximum is vitamin.Experimental results show that after autoclaving, wherein larger with the loss of vitamin A .D.E and B family vitamin, the amount of loss is greatly between 10～60%.General situation is: vitamin A or D loss 10～23%, vitamin B1 loss 20～84%, vitamin B2 loss 10～84%.For this kind of situation, can carry out from two aspects supplementing of vitamin, the one, when formula Design, according to the damaed cordition of autoclaving feed vitamins, the vitamin dosage that scales up, to make up autoclaved loss; The 2nd, by through irradiation (CO
60irradiation) multivitamin after adds the feed after autoclaving or adds through the qualified vitamin of aseptic detection in drinking-water.
Summary of the invention
In order to solve SPF chicken, opening the nutritional need problem in term, the invention provides a kind of SPF chicken and open feed in term.
The present invention is that the technical scheme that adopts of technical solution problem is as follows:
SPF chicken of the present invention opens feed in term, comprises by mass percentage following component: common dregs of beans 15%, 55% corn protein powder 3.6% of corn 63.78%, 43%, DDGS26 albumen 9.85%, stone grain 2%, microlith powder 3.2%, calcium monohydrogen phosphate 1%, salt 0.36%, 60% Choline Chloride 0.05%, 65% lysine 0.58%, methionine 0.17%, threonine 0.01%, premix M-P0.2%, middle chicken multidimensional LV52H0.1%, large chicken multidimensional LV62H0.1% for mineral fowl.
Vitamin A content in this feed is not less than 12000IU/kg, vitamin D content is not less than 1200IU/kg, and content of vitamin E is not less than 20IU/kg, and vitamin B1 content is not less than 3mg/kg, vitamin B2 content is not less than 6mg/kg, and pyridoxamine content is not less than 6mg/kg; Protein content is not less than 17g/kg.
The invention has the beneficial effects as follows:
Compared with prior art, lay eggs early stage feed of SPF chicken of the present invention has clear superiority, and the chicken group survival rate of opening term improves 2.35%, and the uniformity reaches 98.4%.
