Abstract
The invention discloses a special antibacterial acidifying agent for piglet feed and a preparation method of the special antibacterial acidifying agent. The special antibacterial acidifying agent for the piglet feed is prepared from, by weight, 15%-25% of lactic acid, 6%-15% of calcium formate, 12%-20% of citric acid, 8%-15% of benzoic acid, 12%-15% of propyl benzoate and 20%-30% of white carbon black. The special antibacterial acidifying agent for the piglet feed and the corresponding preparation method have advantages that problems of poor antibacterial performance and poor effect of the acidifying agent in improvement of a posterior intestinal segment intestinal tract acid environment are solved, and the special antibacterial acidifying agent is capable of improving acid environments of different intestinal segments and has acidification and antibacterial effects in a wide pH variation range.
Description
Technical field
The present invention relates to a kind of feed addictive and preparation method thereof, more specifically raised the present invention relates to a kind of suckling piglet
Expect special antibacterial type acidulant and preparation method thereof, belong to feed additive field.
Background technology
In recent years, deepening continuously with research, it has been found that the behind of great economic benefit is brought using antibiotic
Drawback, the food-safe uncertain risk brought, the use of antibiotic is caused from politics, economic dispute
With concern, Hangzhou G20 summits in 2016 think that " antibiotic resistance seriously threatens publilc health, economic growth and global economy
Stabilization ".The use of antibiotic under the political economy background will necessarily be subject to national governments strict control or forbid, nonreactive or
The low anti-animal husbandry development epoch are at hand.At present, probiotics, chemical probiotic (mainly oligosaccharide), enzyme preparation, plant
Thing extract (plants essential oil), compound acidulant etc. are known as the substitute products of conventional and effective antibiotic by industry, can carry
Animal growth rate high, improves efficiency of feed utilization, maintains the normal function of animal body, it is ensured that animal health.In these antibiotic
In substitute, acidulant is one of safe pig feed additive for more praising highly, but needs to strengthen the bacteriostasis property of acidulant,
Just adapt to the trend of current nonreactive cultivation.
Feeder acidulant is a kind of environment-friendly type novel fodder additive being widely used in Feed Manufacturing, it is possible to decrease
PH value in animal gastrointestinal tract, for animal endogenous enzymes provide most suitable environment, can be in live pigs such as weanling pig, pork pig, sows
Used in the feed of cultivating link, compound acidulant effect is better than single acidulant, it is now many to add so that organic acid and inorganic acid are compound
Master is added as, both Synergistics overcome the addition defect few with enteron aisle action site etc. greatly of single acidulant, reduce addition
Cost and feeding cost, improve culturing economic effect.
Organic acid type acidulant depends primarily on the PH of stomach itself as a kind of green feed additive, action effect
The dissociation coefficient of value, the molecular weight of acid and acid.Addition acidulant can improve animal gastrointestinal tract acidity, weaken feed acid and combine
Power, softens and the degraded of nutriment endogenous enzymes beneficial to feed, significantly improves crude fat and coarse-fibred digestive utilization ratio.Meanwhile,
Pipe intestinal digesting enzyme content be raised through parasympathetic stimulate liver increase choleresis, enhance fat emulsification into
The process of chylomicron, improves the autonomous digestive utilization ratio to lipid material in feed.In alkaline environment, feed majority is micro-
Secondary element easily forms the extremely low salt of solubility in water, reduces its bioavailability, and heavy metal element is rich in causing excrement
Collection, adversely affects to environment and soil.If using acidulant in feed, it can be with the mineral matter chelant poling in feed
The complex compound being easily absorbed and used, improves absorption and use efficiency of the animal intestinal tract to mineral matter element, creates beneficial to vitamin (such as
VA, VD) the intestines and stomach sour environment digested and assimilated.Macromolecule organic acid (such as citric acid, fumaric acid) may also participate in animal
The energetic supersession of body, they are the intermediate products of tricarboxylic acid cycle, are also one of glycolysis end-product, and gluconeogenesis also may be used
Release energy, form ATP, utilized for body.If in animal body in alimentary canal under sour environment, then for lactic acid bacteria
Growth and breeding can play beneficial facilitation, while fine inhibitory action can be played to the growth and breeding of harmful bacteria, so that
Mucous membrane of small intestine is protected with this, it is ensured that the mucous membrane of small intestine of animal being capable of normal development；Otherwise the nutriment that animal eats can
Digested and assimilated by animal body well, promote animal body and preferably grow, the benign cycle that formation is mutually promoted,
Reach the optimal growth result of animal body.
The content of the invention
Present invention seek to address that the rear intestinal segment enteron aisle acidity enhancement of environment ability of acidulant in the prior art in background technology
The poor problem of the bacteriostasis property of weaker and existing acidulant, there is provided one kind is respectively provided with acidifying in wider pH excursion, presses down
The special antibacterial type acidulant product of suckling piglet of the improved enteron aisle different loci acidified environment of bacterium performance and its corresponding preparation
Method.
In order to realize foregoing invention purpose, its concrete technical scheme is as follows：
A kind of special antibacterial type acidulant of the feed for piglet, including the component of following parts by weight meter is constituted：
A kind of the above special antibacterial type acidulant of the feed for piglet is applied in suckling piglet mixed feed, dosage

Example IV
Influence of the special antibacterial type acidulant of the feed for piglet to Production Performance of Weaning Pigs and diarrhea rate
1st, test site：Chengdu pig farm.
2nd, test combinations：Control group (basal diet group) and test group (the special antibacterial type acid of 0.4% the feed for piglet of addition
Agent group).
3rd, subjects：28 age in days weanling pigs, are randomly divided into 12 groups, every group 6, control group 36, experiment by totally 72
Group 36.
4th, test period：Pre-feeding period 4 days, 28 days formal test time.
5th, test data：Average daily gain, average daily gain, feedstuff-meat ratio, diarrhea rate.
6th, feeding and management：During experiment, raising is responsible for by special messenger, environment is consistent, free choice feeding, drinking-water.Carry out often
The immune sterilization of rule, keeps colony house sanitation and hygiene, observes growing state, carries out relevant record.60 ages in days weigh on an empty stomach.
7th, result：
The special antibacterial type acidulant production performance of the feed for piglet of table 1 and diarrhea rate are analyzed
| Project | Control group | Test group |
| Starting weight (kg) | 7.77±0.44 | 7.64±0.26 |
| End weight (kg) | 19.35±0.46a | 20.67±0.40b |
| Average daily gain | 386.00±21.63a | 434.33±12.01b |
| Average daily gain | 645.37±56.86 | 685.03±49.20 |
| Feedstuff-meat ratio | 1.69±0.05 | 1.58±0.09 |
| Diarrhea rate | 8.27±2.05 | 4.20±1.04 |
Conclusion：
1st, as seen from the above table, test group end weight and average daily gain is significantly higher than control group, be respectively increased 6.8%,
12.52%.Test group average daily gain improves 6.14%, feedstuff-meat ratio reduction by 6.51% compared with control group.
2nd, test group can reduce the Incidence of Diarrhea of weanling pig, compared with control group reduction by 47.12%.The reduction of diarrhea rate from
