Abstract
The invention provides a mould-proof antioxidant capable of increasing pig feed quality. A natural product, namely, soluble chitin, extracted from shrimp and crab shells is taken as a main component of a mould-proof agent and is combined with a composite antioxidant to exert functions, and the mould-proof antioxidant has the characteristics of long mould-proof period, good anti-oxidation effect, no toxic residue, safety and reliability, and can be used for replenishing nutritional ingredients required by the growth of live pigs and increasing the pig feed quality. After eating the feed in which the mould-proof antioxidant is added, the live pigs are increased in feed intake and obviously accelerated in body weight increase, and the slaughtering time is shortened.
Description
Technical field
The present invention relates to the agent of a kind of pig's feed mold-proof oxidation-resistant, relate in particular to a kind of mold-proof oxidation-resistant agent that improves the pig feed quality.
Background technology
Feed mold is the ubiquitous problem in the whole world, it be since in the feed a large amount of breeding of mould cause.Go mouldy easily at high temperature wet season feed, the feed that goes mouldy not only nutritive value reduces, and palatability is affected, and the toxin that produces of bacterium or mould such as aflatoxin can be poisoned live pig and residue in and influenced human health in the pork.Nutriments such as the lipid in the feed constantly carry out oxidation reaction in storage process, cause the photonasty of feed to descend, and nutritive value reduces; Storage life shortens and palatability descends; The feed that can cause that oxidation is serious becomes sour, and protein destroys and pigment oxidation, but also has certain toxicity; Live pig is caused harm to a certain degree, bring bigger loss to the raiser.
Mostly mold-proof oxidation-resistant agent in the market is the simple composite of mould inhibitor and anti-oxidant; The mold-proof oxidation-resistant effect of playing that can only be simple; And be that main mold-proof oxidation-resistant agent also is easy to generate the toxic residue problem with the chemical composition; Exist additivity to poison like benzoic acid, some countries and regions bans use of; Even some is because special smell can cause the repulsion of live pig, reduces the live pig feed intake, influences marketing time.
Summary of the invention
The invention reside in provides a kind of mold-proof oxidation-resistant agent that improves the pig feed quality; Adopt extract soluble chitin and anti-oxidant synergy in the shrimp and crab shells; Not only has good mold-proof oxidation-resistant effect; And can replenish the required nutriment of live pig growth, and accelerate the live pig weightening finish, improve culture efficiency.
The present invention realizes through following technical scheme:
Mould inhibitor: soluble chitin 50-150 part, KI 10-30 part, Potassiumiodate 10-30 part, calcium propionate 10-50 part, origanum oil 1-5 part;
Anti-oxidant: 5-20 part, dibutyl hydroxy toluene 5-20 part, butylated hydroxy anisole 5-20 part, citric acid 1-5 part, inositol 1-5 part;
Totally 1000 parts in mould inhibitor, anti-oxidant and carrier, the residue umber is a carrier;
=1: (1-3): (1-3), the three is beforehand with pulverization process respectively, and making its fineness is 0.1-0.5mm;
Wherein origanum oil obtains through following method:
With putting into supercritical extraction reactor after the pulverizing of 50g wild marjoram herb; Add 200mL75% ethanol as entrainer, the adjusting extracting pressure is 20MPa, and extraction temperature is 55 ℃; The entrainer flow is 0.02mL/min; Carbon dioxide flow is 1.2L/min, extracts and obtains the oily liquids that pale brown look has special aromatic odor after 2 hours, is origanum oil.
50-80 ℃ following stirring and adsorbing 3-5 hour, standing adsorption 20-30 hour again, the sepiolite that will be adsorbed with origanum oil then mixed in proportion with other raw materials and carrier, sieving promptly gets;
Add this additive of 0.5-1.5kg in the feed per ton.
Adopt the natural products soluble chitin that from shrimp and crab shells, extracts as the mould inhibitor main component among the present invention; With the composite antioxidant synergy, it is long to have a mildew-resistant phase, and antioxidant effect is good; Avirulence is residual; Safe and reliable characteristics also can be replenished the required nutriment of live pig growth, improve the pig feed quality.Live pig eats has added feed of the present invention, and feed intake increases, and body weight gain is obviously accelerated, and has shortened the time of delivering for sale.

Table 4 oxidation resistance testing result
Test Example 3: the investigation of live pig growing state
Test and Selection ZhangZhou twins feed corporation,Ltd subordinate pig farm average weight is 660 of the health pig of (38.7 ± 2.3) kg, and is not remarkable through statistical analysis body weight difference.Be divided into 11 groups at random, every group of 6 repetitions, each repeats 10.Experimental group has been added the feed of the mold-proof oxidation-resistant agent that embodiment 1-10 makes, and live pig free choice feeding and drinking-water carry out immunity and expelling parasite by routine, and ramming material and weighing after 30 days calculates daily gain, daily ingestion amount, feedstuff-meat ratio (feed intake/weightening finish); The blank group is not added any mold-proof oxidation-resistant agent, other same experimental group.Experimental result is seen table 5.
Table 5 live pig growing state
Can find out from above-mentioned test, compare with the blank group, add the feed of the mold-proof oxidation-resistant agent that the present invention makes and compared with conventional feed that it is long to have a mildew-resistant phase, anti-mold effect is good; Peroxide value is lower, the characteristics that antioxidant effect is good; Edible live pig daily gain and the daily ingestion amount that has added the feed of the mold-proof oxidation-resistant agent that the present invention makes significantly increases, and feedstuff-meat ratio obviously descends; And the effect of the test group that embodiment 1-6 is corresponding generally is superior to the corresponding test group of embodiment 9-10, especially with the best results of embodiment 1.So the mold-proof oxidation-resistant agent that the present invention makes can significantly improve the culture efficiency of live pig, utilization is worthy to be popularized.
