Abstract

The invention provides a preparation method of a cassava-based pig feed. The preparation method of the cassava based pig feed comprises the following steps: rolling cassava tubers into sheets by using a rolling mill, soaking the rolled cassava tubers into water in which citric acid is added for 2 hours, and filtering; adding the cassava tubers and leaves from which linamarin is removed into a pulverizer together, and pulverizing to obtain cassava pulp; weighing the cassava pulp containing 100kg by weight of cassava flour, adding 20kg of soybean dregs, 5kg of fish meal, 2kg of tangerine peel powder, 1,000g of edible salt, 20g of cerium oxalate, 50g of medical stone powder and 200g of indigowoad roots; adding yeast, mixing uniformly, and fermenting for 2 days; and drying the fermented cassava pulp by a spraying and drying method to obtain the pig feed. The cassava-based pig feed prepared by adopting the preparation method is low in cost and can be directly fed to pigs after being soaked in warm water, and the pigs fed by the cassava-based pig feed can grow healthily and gain weight.

Description

A kind of take cassava as the pig feed preparation method of base material

Technical field

The present invention relates to a kind of take cassava as the pig feed preparation method of base material, belongs to animal feed processing technique field.

Background technology

Cassava is a kind of perennial shrub plant, high more than 1 meter, and leaf is bottle green, and rhizome shape is as red (in vain) potato.Tapioca starch present is about 14-40%.Cassava belongs to Euphorbiales in plant, formal name used at school MANIHOT, is called CASSAVA (cassava or tapioca starch) or TAPIOCA(tapioca in international trade).Cassava originates in South America, after be generalized to the worlds such as Africa, Latin America, Asia some other area plantation.Cassava is one of the world three yampi class (potato, sweet potato, cassava).The place of production, the whole world is horizontally distributed between north and south latitude 30 degree, and vertical distribution is height above sea level less than 2000 meters.

Drought-enduring, resistance to lean, the acid resistance soil of cassava, and photosynthetic efficiency is high, the food energy of unit are exceedes paddy rice, wheat, Chinese sorghum and corn.Cassava is adapted at the tropical and subtropical zone area plantations such as SOUTHERN CHINA, Southeast Asia, South America, Africa, to solve local food problem.Particularly many places, Africa still short-commons, have a lot of people to be still in semistarvation state, implant mass cassava is good selection as staple food.Existing more than the 100 year history of China plantation cassava, according to statistics, has reached 1,300 ten thousand tons to China's fresh cassava output in 2007.

Summary of the invention

The object of the present invention is to provide a kind of take cassava as the pig feed preparation method of base material, to make full use of cassava resource, the pig feed produced has the somatic metabolic activity of conditioner, promote the appetite of pig, increase feed intake, improve abilities of digestive and absorption, enhancing development, improve the function of the price of deed.

The present invention is realized by following technical proposals, and a kind of take cassava as the pig feed preparation method of base material, it is characterized in that step is as follows:

(1) first with roller mill, tapioca root is rolled into sheet, the roll shop building of adjustment roller mill is apart from being 5-10mm, and the tapioca root after rolling with the water soaking that with the addition of citric acid 2 hours, then filters; Soaking in acid condition and make the bitter glycosides hydrolysis of flaxseed in tapioca root, after eliminating animal edible cassava, the hydrogen cyanide of free state after the bitter glycosides of flaxseed is hydrolyzed in hydrochloric acid in gastric juice, can be separated out, to suffocate causing animal tissue cell poisoning potential safety hazard.

(2) tapioca root after bitter for removal flaxseed glycosides is put into pulverizing in flour mill together with cassava leaves and obtain cassava slurry.Cassava leaves is also a kind of good protein feeds, general fresh leaves contains thick protein 7-9%, dry gross protein value 27 ~ 42%, and per hectare can obtain cassava leaves protein and reach 1905kg, far away higher than corn and other cereal crops, can with peanut compared with soybean.Cassava leaves is also rich in beta carotene (53mg/100g) and lutein (92mg/100g).Except methionine is lower than except critical level, other amino acid content enriches, and Compositional balance is more much higher than some high quality forages.The thick protein level of cassava leaf meal and quality alfalfa grass meal is close, cassava leaves 17.54%, clover 20.40%, metabolizable energy value higher (cassava leaves 1.55Mcal/kg, clover 0.81Mcal/kg), crude fiber level lower slightly (cassava leaves 11.49%, clover 19.70%).Cassava leaves Argine Monohydrochloride composition is better than oil meal, grouts, substantially suitable with animal protein; The extractability of cassava leaves albumen is very high, can reach 60%, and can improve digestibility to 90%, and the crude fibre contained by leaf protein and ash content are very low, and easy and tapioca starch forms daily ration and do not reduce digestibility, is raise the good plant protein fodder of livestock and poultry.

(3) claim the cassava slurry containing tapioca starch dry weight 100kg, add dregs of beans 20kg, fish meal 5kg, 2kg orange skin powder, 1000g salt, 20g cerium oxalate, 50g medical stone powder, 200g Radix Isatidis; Adding yeast, mixing, fermenting 2 days; Medical stone: need the trace element such as K, Ca, Mg and Si, Fe, Zn, Cu, Mo, Se, Mn, Sr, Ni, V, Li, Co, Cr, I, Ge, Ti to reach kind more than 40 containing cattle and sheep, also containing pig essential amino acid.Have the toxin such as heavy metal, bacterium that stronger absorption is harmful, there is diuresis, stomach invigorating, protect the liver, the function of relax the muscles and stimulate the blood circulation, strengthen cardiopulmonary vigor, bactericidal antiphlogistic, be beneficial to pig healthy growth; Radix Isatidis has clearing heat and detoxicating ability, promotes the resistance against diseases of pig; Cerium ion is to the formation of organism internal hormone or enzyme or activated efficient catalytic effect, significantly improves cattle and sheep weightening finish, improves cattle and sheep immunity, improves meat, improves meat grade.Orange skin contains in a large number useful to human body vitamin C, carrotene, protein, carbohydrate and many

Plant trace element, be of high nutritive value, have facilitation to pig growth.

(4) adopt the slurry after spray drying process drying fermentation, obtain pig feed powder.

Technique effect of the present invention is: adopt citric acid immersion treatment tapioca root to eliminate the poisoning potential safety hazard of pig food, using containing enriching the cassava leaves of vitamin together as the main material of feed, and add dregs of beans and fish meal makes feed comprise the main food materials of starch, protein and cellulose iii large growth of animal needs, add orange skin powder, cerium oxalate, medical stone powder and Radix Isatidis as additive simultaneously, improve the resistance against diseases of pig, ensure pig healthy growth, improve pig growth efficiency.Because cassava account for the overwhelming majority, cassava is cheap, and pig feed of the present invention is with low cost, directly brews with warm water and feeds pigs, without the need to adding other foodstuffs.
