Laying hens in brooding period premix and preparation method thereof
Technical field
The present invention relates to a kind of laying hens in brooding period premix and preparation method thereof, particularly relate to a kind of laying hens in brooding period 3-10 week premix in age 5% and preparation method thereof.
Background technology
In recent years, along with the development of breeding layer chicken industry, the nutritional need of laying hens in brooding period is required increasingly high, the nutritional need in preceding 2 all ages of laying hens in brooding period especially.Generally search for food in preceding 2 weeks of the egg chick pellet of high nutrition, the mash feed of searching for food gradually after 2 weeks, this is a challenge to chick, so require the feed nutrition level of 3-10 chick in age in week and preceding 2 all feeds to have one well to be connected.Age in egg chick 3-10 week, the height of feed nutrition level directly affected the body weight of laying hens in brooding period, and the brood time body weight whether the performance to the laying hen lifetime performance up to standard is most important.
Present problem is that we have had good chick opening material now, and this opening material is primarily aimed at the 0-2 chick in age in week, and trophic level is higher, and is particulate material, is easy to digestion.But since 3 age in week chick to be converted into from the pellet of eating slaking and eat living mash feed, this to the chick digestive system be very big stress.The mixed feed trophic level that traditional chick premix is made into reduces a lot than particulate material, be unfavorable for the chick growth of later stage, causes the body weight of chick brood time not up to standard, and especially the body weight in 3-10 age in week is not up to standard, and then influences lifelong production performance.
Summary of the invention
The invention provides a kind of laying hens in brooding period 3-10 week premix in age 5% and preparation method thereof, can solve the nutrition connection problem of traditional chick premix and 0-2 chick particulate material in age in week.
For solving the problems of the technologies described above, the present invention adopts following technical proposals:
A kind of laying hens in brooding period 3-10 week premix in age 5%, this premix is made up of following raw materials by weight proportioning:
Raw material weight percentage
Vitamin 0.6-1%
Choline Chloride 1-2%
Trace element 4-6%
Lysine 6-8%
Methionine 3.5-4.5%
Threonine 1-2%
Little ecological 0.4-0.6%
Salt 6-7%
Stone flour 20-30%
Calcium monohydrogen phosphate 20-30%
Fatty powder 8-15%
Carrier 15-20%
The percentage by weight sum of above-mentioned raw materials is 100%.
The raw material preferred weight percent proportioning of said premix is formed as follows:
Raw material weight percentage
Vitamin 0.6%
Choline Chloride 1.7%
Trace element 4%
Lysine 7.4%
Methionine 3.6%
Threonine 1.4%
Little ecological 0.4%
Salt 6.25%
Stone flour 23.8%
Calcium monohydrogen phosphate 24.7%
Fatty powder 10%
Carrier 16.15%
Further, said lysine is the lysine of 70% content; Said fatty powder is the solid-state palm oil of content 98%; Said little ecological active ingredient is bacillus and lactic acid bacteria; Said carrier is a rice bran meal.
The preparation method of a kind of laying hens in brooding period 3-10 week premix in age 5% adopts above-mentioned high-quality premix according to the nutritional need of egg chick, and extracts raw material according to above-mentioned prescription, and raw material is carried out premixed step by step; Vitamin, trace element are mixed step by step; In the step of mixing, the premix incorporation time is 90s.
The present invention is directed to traditional chick premix and be not suitable for the problem of the nutritional need of chick in age in 3-10 week, the egg chick premix of egg chick 3-10 nutritional need in age in week is satisfied in design.This chick premix is satisfied the laying hens in brooding period 3-10 nutritional need in age in week after being made into mixed feed, promotes skeleton development, guarantees that the shin bone of chick is grown up to standard; Add fatty powder, solve the difficulty that liquid fat is added in the feed, improve the energy of chicken feed; Increase amino acid whose addition, promote the growth of chick; Add little ecology, reduce immunological stress, improve the speed of growth, reduce the death rate, make the egg chick brood time body weight body weight that is above standard, for laying cycle of laying hens performance highly yielding ability lays the foundation.
The present invention is through improving the premix nutrient content and mixing step by step; Be primarily aimed at the chick feed intake low, to feed nutrition content and the demanding characteristics of the uniformity; Finally make the body weight of the chick brood time body weight that is above standard, therefore obtain being suitable for the egg chick 3-10 premix in age in week.
Compared with prior art, the present invention has the following advantages and good effect:
The present invention satisfies the laying hens in brooding period 3-10 nutritional need in age in week, better is connected the pellet in early stage simultaneously, promotes that chick carries out the transition to mash feed from pellet smoothly, guarantees the whole nutritional need of chick brood time; Promote bone and muscle development, improve chicken crowd's the uniformity, make the body weight of the chick brood time body weight that is above standard, for laying cycle of laying hens performance highly yielding ability lays the foundation.
The specific embodiment
Below in conjunction with examples of implementation the present invention is made further detailed description.
Embodiment 1
Chick 5% premix made from above-mentioned optimum formula is made into mixed feed nursing egg chick in age in 2000 3 weeks; With do not add that mixed feed that fatty powder and lower common chick 5% premix of amino acid content is made into feeds 2000 3 age in week the egg chick as contrast, its result is difference obviously:
Wherein, said lysine is the lysine of 70% content; Said fatty powder is the solid-state palm oil of content 98%; Said little ecological active ingredient is bacillus and lactic acid bacteria; Said carrier is a rice bran meal.
The preparation method of a kind of laying hens in brooding period 3-10 week premix in age 5% adopts above-mentioned high-quality premix according to the nutritional need of egg chick, and extracts raw material according to above-mentioned prescription, and raw material is carried out premixed step by step; Vitamin, trace element are mixed step by step; In the step of mixing, the premix incorporation time is 90s.
The raw material that the present invention uses comprise vitamin, trace element, Choline Chloride, salt, stone flour, calcium monohydrogen phosphate, rice bran meal, fatty powder, probiotics, single amino acid.Recommended formula adds corn, dregs of beans and 5% premix.The Analysis of Nutritional guarantee value that is made into mixed feed is: crude protein>=19%, crude fibre≤6.0%, coarse ash≤8.0%, moisture≤14.0%, calcium 0.8%-1.3%, total phosphorus>=0.45%, salt 0.3-0.8%, methionine>=0.4%.
The chick 21 age in days average weights of feeding with the chick material of embodiment of the invention proportioning preparation reach 190g, and are high by 18.75% than control group; 28 age in days average weights reach 280g, and are high by 12% than control group; 35 age in days average weights reach 380g, and are high by 8.5% than control group.Concrete data are following:
The chick average weight that the present invention feeds by the chick of embodiment proportioning material, chicken crowd regularity etc. all are superior to traditional chick material, the chick premix that prove the present invention's prescription be can the fine 3-10 of being applicable to chick in all ages nutritional need.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But everyly do not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of technical scheme of the present invention according to technical spirit of the present invention.
