A kind of chick is with biofermentation expanded pellet feed and preparation method thereof
Technical field
The present invention relates to poultry fodder and preparation method thereof, relate in particular to a kind of biofermentation expanded pellet feed that chick is used and preparation method thereof that is applicable to.
Background technology
At present used chick material has broken pellet and powder, and its water content generally is not higher than 12.5% (percentage by weight).Chick goes out shell in hatching factory and is transported to feed lot and needs 24 to 48 hours, and going into house to feed lot still needs the food of just beginning to drink out after a period of time, and chick is hungry because of lack of water therebetween, butt-swelling often occurs, and body weight descends even dewaters death.Therefore chick goes out behind the shell moisturizing as early as possible and opens food very important.
Feed factory is for common digestive tract disease such as prevent the white scour of chicken, have loose bowels; In feed, add antibiotic and medicine; Cause and when suppressing and killing harmful pathogen such as salmonella, Escherichia coli, also suppress and killed probiotics such as lactic acid bacteria, even also cause medicament residue and pathogen to develop immunity to drugs.
In recent years, some Feed Enterprise is added probioticses such as probiotic, but because of high temperature extruding in chicken material pelletization, causes the considerable part beneficial bacterium to be inactivated, and its effect is not remarkable.
In addition, some enterprise releases fermented feed containing probiotics, but all is powder.Powder fermentation toughness, feeding inconvenience, and chick is not liked powder.
Summary of the invention
The problem of technology to be solved by this invention be to provide be fit to chick open food, water content high, do not add antibiotic and medicine and ability prevention and control digestive tract disease, can improve the feed of chick weight gains and survival rate.
Technology to be solved by this invention be problematic in that the preparation method that above-mentioned feed is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is like this:
A kind of chick is used the biofermentation expanded pellet feed, is that the fermentation of substrate inoculation probio bacterial classification liquid is processed by swelling granular, and its swelling granular is processed by the raw material of following weight ratio:
33~55 parts of corns, 20~25 parts of dregs of beans, 2~4 parts of fish meal, 4~6 parts of corn protein powders; 2~4 parts in soya-bean oil, 15~23 parts in inferior powder, 1.1~1.5 parts of calcium monohydrogen phosphates, 0.1~0.25 part of salt; Chicken is with 0.1 part of microelement pre-mix material, 0.03~0.04 part of vitamin premix, 0.4~0.7 part of lysine, 0.14~0.25 part of methionine; 0.03 part of anti-oxidant, 0.15 part of Choline Chloride, 0.45~1.0 part of stone flour.
Described biofermentation expanded pellet feed is circular or oblate.
Moisture 25~the 45wt% that is divided into of above-mentioned biofermentation expanded pellet feed; Be acid; PH value is 3~6, contains the nutriment of following percentage by weight: metabolizable energy 12.55~13.4Mj/Kg, thick protein 21.5~23.5%, calcium 0.85~1.1%, total phosphorus 0.65~0.85%, available phosphorus 0.4~0.5%, lysine 1.05~1.25%, methionine 0.45~0.5%, egg+cystine 0.85~0.95%, salt 0.2~0.35%.
Feed of the present invention makes like this:
(1) according to nutritional need; The part by weight of confirming various raw materials is mixed with complete feed; Mixing the back to the complete diet pellet raw material for preparing pulverizes with 1~1.5 mm sieve hole sizer; Then through feed extruder, extrude and the expanded particle diameter that becomes is 1.5~5 millimeters a circular or oblate particle through 1~1.5 millimeter nib, the swelling granule material of particle oven dry to moisture 7~12wt%;
(2) be substrate inoculation probio bacterial classification with the swelling granule material, comprise each 2-3 kind of bacillus subtilis and lactic acid bacteria;
(3) behind the inoculation probio, pack normal temperature fermentation 3 to 5 days, the expanded pellet feed that can obtain fermenting.
The method of described inoculation probio is: with 150~200 milliliters of the bottled culture mediums of triangle, by the sterile working inoculation, shaking table is cultivated into first class inoculum liquid; Enlarged culture become to be produced strain liquid then, according to the capacity of mixer, and a groove 100~200 kilograms of swelling granule materials processed by above complete diet pellet bulking process of packing into; According to the requirement of product water content 25~45wt%, confirm the requirement of strain liquid, with consumption the strain liquid of swelling granule material 10wt%; Add clean water and be diluted to required strain liquid total amount, spray the strain liquid of dilution while stirring, until the swelling granular uniform absorption; Left standstill about ten minutes; The particulate material surface is dried slightly, disperses, and just can wire up and carry out sealing and fermenting.
The fermentation expanded pellet feed that adopts technology of the present invention to process has following advantage, is specially adapted to out the chick in age in food to two week.
Feed product of the present invention has following advantage:
(1) product is a fine granularity, and moisture height (25~45%) has microbial fermentation fragrance, and poultry is liked pecking and eats.Be used for feeding when young fowl goes out to open behind the shell food or long-distance transport, can keep the skin wet, prevent young fowl dehydration, hunger, advantageously grow with improve survival rate.
(2) pH value of product is 3~6, and the gastroenteric environment of the young fowl of acidifying except that suppressing and killing the pathogen, strengthens proteinase activity in addition, promotes the effect that protein digestibility absorbs.
(3) probiotics fermention produces digestive ferments such as protease, amylase, cellulase, can improve the feed nutrient digestibility, promotes the poultry growth.
(4) product is rich in probios such as bacillus subtilis and lactic acid bacteria, and poultry searches for food the back at intestines and stomach formation dominant microflora, suppresses harmful bacterium breeding, reduces and falls ill.
(5) probiotics fermention produces multivitamin and immune enhancing substance, improves the poultry resistance against diseases, improves survival rate.
Product of the present invention shows through the multiple batches of breeding chickling result of a plurality of units: open food with product of the present invention after chick goes out shell; Free choice feeding; Feed continuously to seven ages in days, the chick average weight gain improves 15~25% than the chick that feeds commercially available chicken material, and survival rate improves 5~10%.
Preparation method of the present invention earlier with raw material puffed one-tenth swelling granule material, with its substrate as biofermentation, has following advantage again:
1, raw material is after expanded, and digestibility improves;
2, the product after expanded is circular or oblate, and certain free-running property is arranged, and feeds conveniently;
3, operation adopts unique multiple probiotics fermention behind the production, can in feed, effectively preserve useful bacillus subtilis and lactic acid bacteria and reach the multiple digestive ferment by its generation.Therefore, contain more useful viable bacteria than the conventional granulates material that adds probiotic, thereby more effectively protect the healthy and growth of poultry with the feed of explained hereafter of the present invention.
