Compound feed for laying hen and preparation method thereof
Technical field
The present invention relates to a kind of compound feed for laying hen and preparation method thereof.
Background technology
In recent years, more and more higher to the requirement of laying-hen compound feed along with the development of breeding layer chicken industry, not only for the trophic level of feed own, raw material framework higher requirement is arranged, the impact that simultaneously breeding environment is produced is also among exploratory development., become increasingly conspicuous on the impact that the laying hen productivity effect produces for summer high temperature, become the new focus of cultivation industry.
For the whole life cycle of laying hen, laying period, be undoubtedly period of greatest concern, has conclusive impact for culture benefit.For many years, basic unit cultivation client exists that the feeding feed stuff structure is single, material quality is uneven, the mode of feeding is coarse, medication is lack of standardization during for Egg Production of Laying Hens etc., so that species the advantage is expressed slow or performance is incomplete, even reduces, cause productivity effect to descend.Particularly in summer high temperature season, heat stress can produce great impact for the Egg Production of Laying Hens level, causes that laying rate descends, egg size reduces, the death rate rises, a series of health factors of immunity degradation etc. produce.
Rely on traditional means such as Wet-curtain temperature reducing not create an interior environment that more adapts to the animal Production requirement from the animal internal body, extraneous cooling means often cause environment temperature unstable greatly, have aggravated the impact for animal body.
Summary of the invention
The present invention starts with from the animal internal body, solve the harmful effect that heat stress brings for animal body, the invention provides a kind of compound feed for laying hen and preparation method thereof, by raw-material preferred, rational raw material framework, so that the heat stress problem that exists summer during the Egg Production of Laying Hens produces the favorable influence effect.
For solving the problems of the technologies described above, the present invention adopts following technical proposals:
A kind of compound feed for laying hen, this mixed feed is comprised of following raw materials by weight proportioning:

Wherein, described vitamin C, formulation is the vitamin dressing, content 95%; Described Choline Chloride, content 60% for its character, is done premix and is processed in the middle of process, prevent moisture absorption sex change; Described phytase, the 5000IU/g of unit, the grace production of Weifang health ground is carried out front premix and is processed, and guarantees the uniformity; Described oyster shell whiting, for high-quality shell raw material comes through pulverizing, digestibility is high.
The raw material that the present invention uses comprise high-grade maize, dregs of beans, steck powder, oyster shell whiting, salt, Choline Chloride and the laying cycle of laying hens compound premix special that full seed, nothing are gone mouldy, also added simultaneously the nourishing additive agent that strengthens immunity, the excessive secretion of restriction adrenal steroid, reduce immunological stress, improve immunity of organisms, improve egg laying performance, the vitamin C of the continuation of strengthening laying eggs.All raw materials of the present invention carry out Crushing of Ultrafine, and sieve is preferably 2.0mm; In the feed mixed process, incorporation time is preferably 200S; For being conducive to corn digesting and assimilating in the laying hen enteron aisle, crush maize granularity 5.4mm.
The Analysis of Nutritive Composition guarantee value is: crude protein 〉=16.00%, crude fibre≤6.00%, coarse ash≤10.00%, moisture≤14.0%, calcium 2.00%-4.50%, total phosphorus 〉=1.25%, salt 0.3-0.8%, methionine 〉=0.35%.
Feeding and management: the semi open model hen house, the three layers of staged in two corridors are raised in cages, 4 plumages/cage, hand fed (day feeds three times), artificial egg collection, round plastic water pipe and nipple-shape supply water, freely drink water, gravity-flow ventilation and illumination, other cultivation programs are normally moved.
Data are processed: the gross weight of laying eggs take test unit as the unit weighing every day, count total egg number, the death of record duration of test, eliminate, the quantity of damaged egg, regularly add up materials amount situation, temperature in 10 o'clock of the every morning record hen house.Test data adopts the SAS9.1 statistical software to analyze, and the result represents that with average and the average variance of least square method P<0.05 is significant difference.
Production performance is analyzed: as can be seen from Table 1, the test group average egg production is high by 0.9374% than control group.Test full phase average egg production test group than control group difference extremely significantly (P<0.01).
The average feedstuff-egg ratio of test group laying hen is low by 0.0341% than control group, and along with the carrying out of test, three phase of test group feedstuff-egg ratio is on a declining curve, and the control group feedstuff-egg ratio is in rising trend.Average feedstuff-egg ratio of full phase of test group is than control group difference extremely significantly (P<0.01).
