Abstract

The invention relates to a piglet puffed compound feed and a preparation method thereof. The piglet puffed compound feed is characterized in that corns, bean pulp, enzymolysis bean pulp, fish meal, whey powder, acyl-hydroxylated emulsified oil powder, calcium hydrophosphate, zeolite powder, enzymic preparations, xylanases, citric acid, lysine and a pre-mixing material are contained in raw materials. After the raw materials are treated at a high temperature and high pressure in a puffing cavity, multiple harmful bacteria are killed; the starch is pasted, so that the defect that the starch cannot be fully utilized by a weaned piglet is overcome to a certain extent while the generation of lactic acid in the gastrointestinal tracts of the weaned piglet is stimulated. After the raw materials are puffed, the antigen activity of beans is lost, so that the stimulation to digestive tracts and especially to intestinal villi is avoided. Based on the puffed treatment, the utilization ratio of protein and prandial fibers are improved, so that the absorption utilization rate of the piglet to the feed is improved; the durchfall and diarrhea of the piglet are reduced; the immunity of the piglet is enhanced. Thus, the daily gain and feed conversion ratio of the piglet are improved effectively.

Description

A kind of piglet expanding compound feed and preparation method thereof

Technical field

The present invention relates to a kind of animal feed, particularly a kind of piglet expanding compound feed.

Background technology

In propagating the process of pig artificially, be in the growth phase that health is grown rapidly behind the weaned piglet, but early-weaned piglets can reduce feed intake usually, and that the low reason of feed intake is that mainly ablactation stress causes is physically different.Therefore, the piglet of early weaning has special requirement to feed, if the formula of piglet feed that uses and technique science not, gastricism, the food digestion rate that then often easily causes piglet is low, over-burden and cause diarrhea for intestines and stomach, thereby causes the body development of piglet bad.Adopting bulking process to process is the good method that addresses this problem.Expanded the amylum body of cereal is broken, starch gelatinization, thereby can improve digestibility.Also can improve in addition the digestibility of dietary fiber.Dregs of beans is protein raw material main in the pig starter feed, but because it contains multiple ANFs, easily cause grice diarrhoea, affecting soybean antigen contained in the absorbing of nutriment, particularly bean material is the Major Nutrient reason that causes the intestinal villus atrophy.Expanding treatment can be eliminated soybean antigen well, and improves the utilization ratio of soybean protein.

Summary of the invention

An object of the present invention is the technical problem that will solve for above, provide a kind of balanced in nutrition, can improve piglet stomach digestive efficiency and body weight gain rate, reduce pig starter feed of grice diarrhoea rate and preparation method thereof.

The invention provides a kind of expanded pig starter feed, contain the component of following part by weight in the raw material: corn 25～65, dregs of beans 5～15, enzymolysis dregs of beans 5～15, fish meal 1～6, whey powder 2～7, acyl hydroxylating emulsification oil-bound distemper 3～10, calcium monohydrogen phosphate 0.3～0.5, zeolite powder 0.6～1.2, enzyme preparation 0.05～0.1, acidulant 0.01～0.15%, lysine 0.1～0.5, premix 1～2;

The preferred phytase of described enzyme preparation, non-starch polysaccharide enzyme or zytase;

Described acidulant optimization citric acid.

Prepare the method for above-mentioned pig starter feed, may further comprise the steps:

(1) quantitatively takes by weighing each raw material components;

(2) corn, dregs of beans, enzymolysis dregs of beans are pulverized rear the mixing;

(3) mixture is added wet-process puffing machine and carry out expandedly, expanded rear material cools off by cooler;

(4) will cool off rear crushing material;

(5) crushing rear material and other raw materials are mixed;

(6) all raw materials are joined modulator, the steam that passes into 90 ℃ was modulated 5～7 minutes, then pushed granulation under 80 ℃ of conditions;

(7) under 90 ℃ of conditions, feed granules is dried;

(8) cooling, packing.

The present invention has following remarkable advantage:

1, raw material can kill multiple harmful germ through high temperature, the HIGH PRESSURE TREATMENT of Builking cavity, makes feed satisfy relevant hygienic requirements, thereby effectively prevents animal alimentary canal diseases.2, starch has been destroyed the integrality of starch granule structure by gelatinization after the expanding treatment, has increased the sensitiveness of enzyme to starch, has remedied to a certain extent the deficiency that weanling pig utilizes starch, can stimulate the generation of lactic acid in the Gastrointestinal Tract of Weanling Piglets simultaneously.3, soybean antigen is lost activity, avoid alimentary canal particularly to the stimulation of intestinal villi.Improved the utilization rate of protein and dietary fiber by expanding treatment, and then can improve piglet to the absorption rate of feed, reduce diarrhoea and the diarrhea of piglet, can effectively improve daily gain and the feedstuff-meat ratio of weanling pig, especially more obvious than early stage results after wean.4, grease is after the modification of acyl hydroxylation, and unsaturated double-bond significantly reduces, and has improved oxidation resistance.Increased hydrophilic radical, greatly improved emulsibility and aqueous emulsion stability, more be conducive to absorption and the utilization of animal, the prevention fatty liver strengthens immunity.

Preparation process: with example 1.

Implementation result of the present invention:

Use pig starter feed provided by the invention to test on kind pig farm, Gongzhuling of Jilin Province ten room.120 of body weight 13kg left and right sides market pigs are selected in test, are divided at random 3 groups, and the male and female ratio between group is identical.Control group uses common pig starter feed to feed.I organizes the inventive embodiments 1 of feeding, and II organizes the inventive embodiments 2 of feeding.

Test period one month.Test and adopt free choice feeding, drinking-water, it is conventional definite that the test site is pressed in test pig house temperature, humidity, illumination, and the epidemic prevention system is according to the test site routine operation.

Testing index and method:

Test the 1st day and the 30th day morning 8 empty stomaches the examination pig is weighed, take the hurdle as each stage body weight of unit record and feed consumption rate to calculate average daily gain, average daily ingestion amount and to expect anharmonic ratio.Take the hurdle as the number of having loose bowels of unit record every day examination pig, in order to calculate diarrhea rate.

Average daily ingestion amount (ADFI)=feed consumption rate/fate

Material anharmonic ratio=feed consumption rate/weightening finish

Diarrhea rate (%)=total diarrhoea number/(a piglet number * test fate) * 100.

	The I group	The II group	Control group
				Feedstuff-meat ratio	1.048	1.034?	1.21?
Diarrhea rate %	2.07?	1.98	8.23
				Survival rate %	100	100	97.5

Learn by this test, the pig starter feed that uses the embodiment of the invention 1 and embodiment 2 the to provide piglet of feeding, obviously effective than what use common pig starter feed to feed in the control group.Growth performance aspect, daily gain are higher than control group and feedstuff-meat ratio is significantly higher than control group.The health status aspect uses mortality and the diarrhea rate of embodiment 1 and 2 two test group of embodiment all to be lower than control group, and difference is extremely remarkable.
