Abstract

The invention relates to a weanling pig compound feed containing earthworm powder as a protein source, belonging to the feed field. The weanling pig compound feed provided by the invention contains the following components in parts by weight: 50-70 parts of corn, 15-25 parts of extruded-soybean, 5-15 parts of soybean meal, 2-6 parts of earthworm powder and 1-6 parts of lactose. The earthworm powder used in the invention is manufactured by the fresh Japanese bloodworms after being dried in the shade and crushed, which are rich in animal protein, antibacterial peptide and amino acid, and is added to the weanling pig compound feed in two stages according to a certain proportion, so that the compound feed can effectively reduce the diarrhea rate of the weanling pig and improve the growth performance of the weanling pig.

Description

A kind of weanling pig mixed feed

Technical field

The present invention relates to the animal and fowl fodder field, relate to a kind of weanling pig mixed feed, more specifically, relate to a kind of weanling pig mixed feed that contains earthworm powder as protein sources.

Background technology

Plasma protein and fish meal are weanling pig protein feeds commonly used, but these expensive raw material price are used in actual production and received certain restriction.Bloodworm is the saprophagous character animal, likes living in the soil that contains a large amount of organic matters, can utilize vegeto-animal organic waste, propagates artificially in a large number.Its feeding habits is wide, ight soil of livestock and poultry and straw, various aquatic foods, dried green grass, and leaf, melon and fruit, dish skin even hogwash etc. can both eat after fermentation.Earthworm powder is dried in the shade by fresh Japanese red earthworm and processes after pulverizing; Protein content is up to 70%, and is suitable with imported fish meal, and wherein arginine content is higher 2～3 times than fish meal; Tryptophane is 7 times of beef liver, also contains more carrotene and multivitamin and trace element.Be rich in animal protein, antibacterial peptide and amino acid, pig feed is advanced in interpolation can obtain the effect identical with SDPP, is that weanling pig produces the novel available efficient protein of searching source establishment foundation.

Summary of the invention

In order to address the above problem, the present invention provides a kind of weanling pig mixed feed.

Weanling pig mixed feed provided by the invention, it contains following components by part by weight:

Corn 50-70;

Expanded soybean 15-25;

Big dregs of beans 5-15;

Earthworm powder 2-6;

Lactose 1-6.

Preferably, described mixed feed contains following components by part by weight:

Corn 55-60;

Expanded soybean 18-20;

Big dregs of beans 5-10;

Earthworm powder 3-5;

Lactose 2-5.

Further, described mixed feed also can contain the protein sources of 1-3 weight portion, and said protein sources is preferably one or more in SDPP, globulin powder and the fish meal.

Further, described mixed feed also can contain the premix of 5-10 weight portion.Said premix can be routine and adds the premix in the mixed feed to, can commercially available or preparation voluntarily.Among the present invention, can contain the premix of following weight parts prescription: salt 5.0-5.5, sucrose 16-19, soybean oil 35-43, calcium monohydrogen phosphate 12-16, stone flour 12-15, lysine 3-4, methionine 1.2-1.5, threonine 0.8-1.2, tryptophan 0-0.3.

The present invention also is provided for preparing the method for the earthworm powder of said mixed feed, and it comprises the steps:

Earthworm is raised in fresh pig manure: in the base-material of mellow soil 30-40%:60-70%, the control water content is 30-35%, and the control raising temperature is 25-28 ℃, raises 40-45 days;

Dry in the shade after fresh earthworm chosen, roll pulverizing, cross 40 mesh sieves.

The weanling pig mixed feed that the present invention produces is rich in each required seed amino acid of weanling pig 30 age in days to 45 ages in days growth, trace element, and vitamin etc. can reduce the diarrhoea of wean back piglet, improve its production performance.The earthworm powder that the present invention uses is dried in the shade by fresh Japanese red earthworm and processes after pulverizing; Be rich in animal protein; Antibacterial peptide and amino acid; Added a certain amount of earthworm protein as the weaning pigs protein sources, the weanling pig production performance is superior to other processed group, particularly ADG and ADFI obviously is superior to adding SDPP, fish meal processed group.Earthworm powder is as protein sources, and the diarrhoea that also can reduce weanling pig to a certain extent takes place.In addition, for expensive imported fish meal and SDPP, the earthworm powder production cost is lower, can be used as novel environment friendly animal feed protein sources and promotes the use of.

Test Example 1

Animal used as test: select average 30 age in days weanling pigs (long * big binary), be divided into 4 processing at random according to body weight, sex, each handles 5 repetitions, and each repeats 6-8 pig, public female balanced proportion.

The experiment daily ration: two phases carried out before and after this test was divided into, feed early stage material of wean 0-10d, the 11-13 excessively material (mixing) of feeding, the 14-28d later stage material of feeding by front and back phase material, and each is handled and sees table 1.Each handles the daily ration kind and the major protein source is seen table 2 and table 3 for details.

Phase piglet diet kind major protein source before and after table 1 test

Table 2 test feed formula in early stage and nutrient composition content

Table 3 test later stage feed formula and nutrient composition content

Testing regulations:

Test begins about 30 ages in days during from weaned piglet, carries out altogether 28 days, finishes about 58 ages in days.Early stage, daily ration was fed 10 days, and the transitional period is 3 days, and the later stage fed 15 days.The ratio of first day daily ration front and back phase material of transition is 2:1; The ratio of second day daily ration front and back phase material of transition is 1:1; The ratio of the 3rd day front and back of transition phase material is 2:1.The weighing by weight proportion of transition material is fed after mixing again.

The feeding of piglet, management, drug therapy are undertaken by the pig farm established procedure.

Feed in on-test, early stage and finish and the later stage weighing piglet body weight when finishing of feeding, carry out morning on an empty stomach, and off-test was cleaned out feeder for piglet in preceding 12 hours, and piglet is weighed after hungry 12 hours.

Observe the health status of piglet in the entire test, dead, naughty piglet of record and diarrhoea, medicining condition.

Diarrhea rate (%)=experimental period diarrhoea piglet head/(a test piglet number * test fate) * 100%

Average daily gain (ADG)=(off-test litter weight-on-test litter weight)/test pig's head number/test fate

Average day feed consumption (ADFI)=consumption feed/test pig's head number/test fate

Feedstuff-meat ratio (F/G)=ADFI/ADG

Death rate (%)=superseded pig's head number/test pig's head number * 100%

Experimental result:

28 days weanling pig production performances of table 4 test

Can find out according to table 4, add a certain amount of earthworm protein as the weaning pigs protein sources, the weanling pig production performance is superior to other processed group, particularly ADG and ADFI obviously is superior to adding SDPP, fish meal processed group.Earthworm powder is as protein sources, and the diarrhoea that also can reduce weanling pig to a certain extent takes place.For expensive imported fish meal and SDPP (homemade SDPP 38000-40000 unit/ton; Imported fish meal 13000-15000 unit/ton 2011-2012 price); The earthworm powder production cost is lower, promotes the use of as long as there is suitable base-material source (20000 yuan/ton of purchasing prices) to can be used as novel environment friendly animal feed protein sources.

The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
