Abstract

The invention discloses a mixed feed of potato starch residues and corn stalks. The mixed feed is composed of, by weight, 40% of fine materials, 15% of corn stalks and 45% of potato starch residues, and the fine materials comprise 50-55 parts of corn flour, 10-12 parts of soybean meal, 10-12 parts of fish meal, 8-10 parts of wheat bran, 1.2-1.5 parts of stone powder and 2-4 parts of linseed oil. The mixed feed is high in quality, worries of potato starch processing plants are removed, the feed formula is reasonable in matching, growth of livestock is promoted, the weight is increased, and the quality of meat of the livestock is improved.

Description

A kind of potato starchy residue and the method for corn straw mixture feedstuff

Technical field

The invention belongs to field of fodder, be specifically related to a kind of potato starchy residue and corn straw mixture feedstuff Method.

Background technology

Rhizoma Solani tuber osi is the fourth-largest cereal crops in the world, is only second to Semen Tritici aestivi, Oryza sativa L. and Semen Maydis.Cultivate horse in the world The country of bell potato has 148, is mainly distributed on the ground such as Asia, Europe.At present, China is Big Rhizoma Solani tuber osi produces plantation state, according to FAO's statistics in 2008, the potato planting face of China Long-pending more than 85,000,000 mu, annual production has broken through 7200 × 104t, and potato planting area and total output all jump Rank first in the world.In northern China most area, the main deep processing of Rhizoma Solani tuber osi is used for producing starch and bean noodles, Substantial amounts of potato starchy residue can be produced in the course of processing.General processing 1t Rhizoma Solani tuber osi can produce 9t Ma Ling Sweet potato starch slag.Potato starchy residue is that a class is aqueous, cell debris and the processing byproduct of remaining starch granule, Its (dry) main component is protein 4.6%～5.5%, crude fat 0.16%, crude fibre 9.46%, Sugar 1.05%.But fresh potato fecula water content is up to 90%, certainly carry disease germs up to 33 kinds, be difficult to store, Transport, putrid and deteriorated after produce stench, cause environmental pollution；If drying, high cost, increase enterprise and bear Load, generally by fresh potato slag directly as feed conversion, but in fresh potato starchy residue protein content low, Crude fiber content is high, palatability is poor, the freshest potato starchy residue directly as feedstuff utilization rate very Low.If potato starchy residue is buried process as waste residue, a large amount of owing to potato starchy residue containing Inorganic salt, can cause the pollution of soil and groundwater.Therefore, the development and utilization of potato starchy residue is always It it is a troubling difficult problem.Containing substantial amounts of starch, cellulose, hemicellulose, really in potato starchy residue The available composition such as glue, contains a small amount of protein simultaneously, can have higher exploitation as fermentation medium Value.Abroad begin to carry out the exploitation research of potato starchy residue as far back as the forties in 20th century, And China just starts the research work of this aspect in late 1990s.At present, potato starchy residue is opened Send out and utilize mainly to process and extract advantageous product or as culture medium fermentation production of protein feedstuff.And by horse The report of bell sweet potato starch slag fermenting and producing ensilage abroad only has okinea et al., and research report feeds Ma Ling Sweet potato starch slag ensilage does not produces impact to dry matter intakes amount, milk production and the milk composition of milch cow；Domestic It is blue or green that only Yan Xiao ripple research report potato starchy residue and straw mixed silage material can substitute whole-plant corn completely Bin stock feeding cow, does not makes significant difference to milch cow dry matter intake and milk cow production performance etc., and Rhizoma Solani tuber osi is formed sediment Process and the transition problem of granulated slag are never well solved.

Summary of the invention

The problem that the invention aims to process and the conversion solving potato starchy residue further, it is provided that A kind of potato starchy residue and the method for corn straw mixture feedstuff, produce the mixture feedstuff of a kind of high-quality, solve Except the trouble and worry of potato starch processing factory, feed formula collocation rationally, promotes the growth of domestic animal, increases Body weight, improves livestock meat quality.

To achieve these goals, one potato starchy residue of the present invention and corn straw mixture feedstuff, including The raw material of following portions by weight is made up of 40% concentrate+15% corn straw+45% potato starchy residue.

In described raw material, concentrate is: Semen Maydis powder 50-55 part, soybean meal 10-12 part, fish flour 10-12 part, wheat Bran 8-10 part, stone powder 1.2-1.5 part, siritch 2-4 part.

In described raw material, corn straw is any one of ensiling or fresh corn straw.

Its preparation method: step one) the Semen Maydis powder in concentrate, soybean meal, fish flour, Testa Tritici, stone powder, recklessly Oleum Sesami, after being sufficiently mixed, packages spare, it is thus achieved that concentrate；

Step 2) according to 40% concentrate+15% corn straw+45% potato starchy residue, after being sufficiently mixed, Potato starchy residue and corn straw mixture feedstuff.

In place of beneficial effects of the present invention:

Present invention utilizes potato starchy residue, wherein potato starchy residue be that a class is aqueous, cell debris and The processing byproduct of remaining starch granule, its (dry) main component is protein, crude fat, slightly fibre Dimension, sugar, etc. the present invention again on the basis of feedstuff carried out nutrition comprehensively arrange in pairs or groups, compatibility rationally can promote house The growth of poultry, puts on weight, and improves livestock meat quality.

Detailed description of the invention

Below by way of specific embodiment, the invention will be further described, but the right model that the present invention is protected Enclose and be not limited only to following example.

Embodiment 1

Weigh Semen Maydis powder 50 parts, soybean meal 10 parts, fish flour 10 parts, 8 parts of Testa Tritici, stone powder 1.2 parts, recklessly 4 parts of Oleum Sesami, after being sufficiently mixed, packages spare, it is thus achieved that concentrate；Weigh again and take 40g concentrate+15g corn stalk Stalk+45g potato starchy residue, corn straw is the straw after ensiling, be sufficiently mixed after, potato starchy residue With corn straw mixture feedstuff.
