Abstract

An SPF chicken growing period feed relates to the technical field of poultry feeds and solves a problem of requirement of nutrition in a growing period of SPF chickens. The SPF chicken growing period feed includes following components, by mass: 58.9% of corn, 12.3% of a 43% common soybean meal, 1.4% of a 55% corn protein powder, 12.85% of DDGS26 protein, 10% of whole-fat rice bran, 2.3% of fine limestone powder, 0.7% of calcium hydrophosphate, 0.3% of salt, 0.05% of 60% choline chloride, 0.41% of 65% lysine, 0.22% of methionine, 0.17% of threonine, 0.2% of a mineral poultry pre-mixed material M-P, and 0.2% of multiple-vitamin for middle chicken LV52H. The SPF chicken growing period feed has obvious advantages, can increase a chicken crowd survival rate in the growing period by 2.9% and enable a uniformity to reach 98.6%.

Description

SPF chicken finishing period feed

Technical field

The present invention relates to bird feed technical field, be specifically related to a kind of SPF chicken finishing period feed.

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 the impact of biological characteristics, nutritional need and the feed sterilization that takes into full account SPF chicken on nutrition are 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 formulate and Feeding Prescription Design all will take into full account the difference of SPF chicken and common chicken at its trophic level, therefore in the time designing feed formula, to take into full account following some:

1) in the time of 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), compared with common chicken, because SPF chicken is all the time in barrier system or isolator, living environment is relatively stable, and (it is 14 DEG C～28 DEG C 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, when 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, in the time of 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 ⁶⁰irradiate) after multivitamin add feed after autoclaving or add through the qualified vitamin of aseptic detection in drinking-water.

Summary of the invention

In order to solve the nutritional need problem of SPF chicken at finishing period, the invention provides a kind of SPF chicken finishing period feed.

The present invention for the technical scheme that technical solution problem adopts as follows:

SPF chicken finishing period feed of the present invention, comprises following component by mass percentage: common dregs of beans 12.3%, 55% corn protein powder 1.4% of corn 58.9%, 43%, DDGS26 protein 12 .85%, full-cream rice bran 10%, microlith powder 2.3%, calcium monohydrogen phosphate 0.7%, salt 0.3%, 60% Choline Chloride 0.05%, 65% lysine 0.41%, methionine 0.22%, threonine 0.17%, premix M-P0.2%, middle chicken multidimensional LV52H0.2% for mineral fowl.

Vitamin A content in this feed is not less than 6000IU/kg, vitamin D content is not less than 500IU/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, SPF chicken finishing period feed of the present invention has clear superiority, and the chicken group survival rate of finishing period improves 2.9%, and the uniformity reaches 98.6%.
