Abstract
The invention provides a mixed feed for weaned piglings and a preparation method thereof. Raw materials for the mixed feed comprise, by weight, 40 to 48% of corn, 8 to 12% of soybean meal, 8 to 12% of broken rice, 10 to 15% of swelling soybean, 2 to 5% of soybean oil, 1 to 3% of plasma protein powder, 5 to 10% of whey powder, 2 to 5% of domestic fish meal, 0.5 to 0.8% of calcium formate, 1.0 to 1.5% of calcium dihydrogen phosphate, 0.1 to 0.3% of salt, 0.2 to 0.4% of an acidifying agent, 0.05 to 0.15% of an emulsifier, 0.02 to 0.05% of probiotics, 0.03 to 0.07% of choline chloride and 0.04 to 0.28% of nanometer zinc oxide. All the raw materials are subjected to fine grinding, and 100% of the ground raw materials are screened with a 30 mesh standard sieve. The invention enables the solving of the problems of severe diarrhoea, poor growth vigor, bad fur and the like of weaned piglings caused by conventional feeds for the weaned piglings.
Description
Technical field
The present invention relates to a kind of Weanling pig compound feed and preparation method thereof.
Background technology
At present, in the application of animal nutrition and feed, zinc source additive mainly contains zinc sulfate and zinc oxide, prevents and reduces that zinc sulfate does not have advantage aspect diarrhoea weanling pig.Heavy dose of common zinc oxide (3000mg/kg) is widely accepted in the application that weanling pig reduces in diarrhoea, but the use of heavy dose of common zinc oxide has brought problems: use for a long time high dose zinc oxide can affect piglet skin and a quilt hair situation, the piglet skin whitening, by staple length and tarnish, cause the late growing stage retardance, the zinc of high dose also can make the animal product quality reduce, and because the zinc oxide bioavailability is low, most of with ight soil discharge, serious environment pollution.In June, 2009, No. 1224, The Ministry of Agriculture of the People's Republic of China, MOA bulletin promulgates, stipulated after the weaned piglet that in front 2 all mixed feeds, the addition of the zinc of zinc oxide form is no more than 2250mg/kg.And according to previous experiences, the zinc oxide 2250mg/kg that adds traditional form can not play good Antidiarrheic effect.In addition, along with global economic growth and inflationary pressure, the internal feed cost of material continues to raise up.
Summary of the invention
The present invention provides a kind of Weanling pig compound feed and preparation method thereof for solving problems of the prior art, can solve the having loose bowels of traditional Weanling pig compound feed, growing way, hair color problem.
For solving the problems of the technologies described above, the present invention adopts following technical proposals:
A kind of Weanling pig compound feed, this mixed feed is comprised of following raw materials by weight proportioning:
Raw material weight percentage
Corn 40-48%
Dregs of beans 8-12%
8-12% cracks rice
Expanded soybean 10-15%
Soybean oil 2-5%
SDPP 2-4%
Whey powder 5-10%
Domestic fish meal 2-5%
Calcium formate 0.5-0.8%
Calcium dihydrogen phosphate 1.0-1.5%
Salt 0.1-0.3%
Acidulant 0.2-0.4%
Emulsifying agent 0.05-0.15%
Little ecological 0.02-0.05%
Choline Chloride 0.03-0.07%
Nano zine oxide 0.04-0.28%
The percentage by weight sum of above-mentioned raw materials is 100%.
Nanometer technology refers to study atom, molecular structures and interactional technology in measuring 1nm～100nm scope, material is by with " nanometer " technology " refinement " afterwards, namely lose original characteristic, directly show physics, the chemistry and biology characteristic that makes new advances with atom, molecule and material on nanoscale.Nano zine oxide is a kind of novel high function fine inorganic product geared to the 21st century.Its particle diameter claims again ultra-fine zinc oxide between 1nm～100nm, and Product Activity is high, and the function of shielding infrared ray, ultraviolet ray and sterilization is arranged.The nano zine oxide powder especially can decomposite the electronegative electronics that moves freely in the sun voluntarily under ultraviolet irradiation, stay simultaneously the hole (h+) of positively charged.This hole can be activated airborne oxygen and become active oxygen, and extremely strong chemism is arranged, can with gas chromatography generation oxidation reaction (comprise bacterium in organic matter), thereby most germs and virus are killed.Relevant quantitative test shows: when nano oxidized zinc concentration was 1% in 5rain, the sterilizing rate of staphylococcus aureus was 98.86%, and colibacillary sterilizing rate is 99.93%.
The present invention is directed to conventional oxidation zinc and add according to the Ministry of Agriculture 1224 bulletin, the rare weak effect of Weanling pig compound feed tension, the problem such as growing way is poor, fur is poor have designed the Weanling pig compound feed that can improve above-mentioned performance.This mixed feed contains nano zine oxide, and nano zine oxide can by affecting the synthetic and level of the bioactivators such as insulin, zinc finger protein, be strengthened nucleic acid and protein metabolism; On the other hand, promote intestinal villus and enterocyte hyperplasia, division to accelerate by zinc finger protein, the intestinal mucosa that quick reparative factor pig ablactation stress causes and fine hair damage, the gastrointestinal ulceration that effective treatment causes because of ablactation stress, suppress simultaneously the harmful bacteria growth, safeguard the gut flora balance.Because it has stronger astriction, can reduce enterocinesia, be conducive to the reparation of impaired of enteron aisle, be conducive to the absorption of nutriment, also can reduce the incidence of pigling diarrhoea.
The present invention is by picking of raw material and retrofit, and the raw material weight percentage proportioning of described mixed feed is composed as follows:
Raw material weight percentage
Corn 44.6%
Dregs of beans 15.1%
Crack rice 9.8%
Expanded soybean 12.5%
Soybean oil 2.5%
SDPP 2.5%
Whey powder 8.0%
Domestic fish meal 2.5%
Calcium formate 0.6%
Calcium dihydrogen phosphate 1.2%
Salt 0.18%
Acidulant 0.25%
Emulsifying agent 0.10%
Little ecological 0.03%
Choline Chloride 0.04%
Nano zine oxide 0.1%
Further, described acidulant active ingredient is benzoic acid, fumaric acid and DL-methionine hydroxy calcium; Described emulsifying agent active ingredient is the soybean lecithin extract, i.e. haemolysis lecithin; Described little ecological active ingredient is bacillus and lactic acid bacteria; Nano zine oxide refers to the zinc oxide of particle diameter between 1nm～100nm.Wherein also contain carrier in acidulant and little ecology, but carrier is inoperative in the formula of this mixed feed.
A kind of preparation method of Weanling pig compound feed adopts the mixed feed of above-mentioned high-quality, and extracts raw material according to above-mentioned formula according to the nutritional need of weanling pig, raw material is carried out Crushing of Ultrafine make it 100% by 30 mesh standard sieves.Search for food for ease of weanling pig, product is carried out little broken kernel, granularity is between the 8-15 order.
Compared with prior art, the present invention has the following advantages and good effect: significantly reduced the consumption of zinc oxide in the wean piglet diet, reduced environmental pollution, for the mankind's health is benefited.Improved the index such as the rare performance of tension, piglet growing way, fur color of Weanling pig compound feed.
The specific embodiment
The present invention is described in further detail below in conjunction with examples of implementation.
