The pH value is one of key factor of digestive environments in the animal body.The pH value is 2.0～2.5 in the animal stomach, the pH value is 5～7 in the small intestine, this sour environment is that feed ingredient is is fully digested and assimilated in vivo, profitable strain is rationally grown, pathogenic microorganism is subjected to the necessary condition that effectively suppresses, guarantees that these conditions can reach the purpose that improves growth of animal performance and efficiency of feed utilization, enhancing body resistance against diseases.Yet the growth of young animal digestive system is imperfect as yet, the gastric acid secretion deficiency, and digestive enzyme activity is low, and intestines and stomach pH value is higher than the optimum range of enzymatic activity and beneficial microbe growth.The nutritionist is that fodder acidulant (as sulfuric acid, hydrochloric acid, orthophosphoric acid etc.) reduces pH value in the alimentary canal by add the acid of external source type in the young animal feed, for animal provides the suitableeest digestive tract environment, reduce diarrhoea, promote digestion, to satisfy the needs of nutrition and diseases prevention.Nowadays, acidulant has become important additives arranged side by side with probiotic, enzyme preparation etc. after antibiotic, though it is still impossible to cancel the use in mixed feed of antibiotic and antibacterials in a short time, be well worth doing with acidulant instead of part medicine class additive.
Inorganic acidulant reaches lower interpolation cost often for using in the production owing to have stronger acidity, the inorganic acidulant that uses is mainly phosphoric acid at present, add the very fast decline of pH value that phosphoric acid can make feed in the feed, the corrosivity of phosphoric acid is littler than sulfuric acid and hydrochloric acid, and animal, equipment and human body are all compared safety.
The method of adding phosphoric acid usually is that orthophosphoric acid is adsorbed on (as calcium carbonate, white carbon, talcum etc.) on the general carrier, adds in the feed then.The problem that present phosphoric acid additive in use exists mainly is: (1) if contain stone flour, sodium bicarbonate, zinc oxide isogonic alkaline matter in the feed, chemical reaction heating aerogenesis can take place in phosphoric acid additive and these alkaline matters; (2) the phosphoric acid additive can destroy in the feed other meta-alkalescence nutrient such as carnitine, vitamins product etc., has a strong impact on the service efficiency of phosphoric acid and the effect of other nutritional labeling; (3) addition is big, the cost height, and cost performance of product is very low.
Recently the researcher studies the release tech that delays of acidulant, mainly is to adopt coating technique, and acidulant can slowly be discharged in alimentary canal, and most of acid can enter alimentary canal and bring into play its effect.But there are defectives such as complex process, cost of material height in these technology.

The test example
Experimental animal: select 96 of 30 age in days weanling pigs for use, body weight is 5.7～6.4kg.
Experimental design: by body weight experimental animal is divided into 4 test group at random, establishes 4 repetitions for every group, 6 pigs of every repetition.The following daily ration of feeding respectively: control group (not adding acidulant); Processed group A1(adds the acidulant 3# of proportion 0.3%); Processed group A2(adds 0.35% acidulant 3#); Processed group A3(adds 0.4% acidulant 3#).Daily ration consists of (proportion): corn 59.8%, dregs of beans 25.0%, fish meal 4.0%, whey powder 5.0%, stone flour 0.9%, calcium bicarbonate 1.0%, salt 0.3%, phospholipid powder 3.0%, top batch mixing 1.0%.Particulate material is raised, group feeding, and every day, feeding was 4 times, freely drank water.Test 30 days full phases.
Claim starting weight in on-test, weigh weekly then 1 time that the statistics feed intake is calculated daily gain and feedstuff-meat ratio, and observed the diarrhoea situation every day.
Result of the test: see Table 1:
The result of use of table 1 phosphatic type fodder acidulant of the present invention 3#
.
As seen from the above table, add acidulant 3# of the present invention and can effectively reduce the diarrhoea degree of weanling pig in 30 age in days weanling pigs, the diarrhea rate of A1, A2, A3 group is low by 2.4%, 3.9%, 3.7% respectively than control group, and the diarrhea rate of A2 group is minimum, be 5.8%, significantly be lower than control group.From this result of the test, the additive capacity of this acidulant product prevents the effect of diarrhoea best when 3500g/t.
Acidulant of the present invention can improve digestibility and the utilization rate of nutriment, strengthens metabolism, improves the speed of growth.As seen from Table 1, the daily gain of A3 group is the highest, is 309g, secondly is the A2 group.The feedstuff-meat ratio that adds this acidulant all is higher than control group, and wherein the feedstuff-meat ratio of A2, A3 group is more approaching, is respectively 1.29 and 1.27.From this result of the test, this acidulant addition is when A3, and its production performance effect is the most desirable, but from the effect of its prevention diarrhoea, effect during a little less than the A2 addition, therefore this product recommendation interpolation proportion optimum value is between 0.35～0.4% in the weanling pig daily ration.
Product acidulant 1# of the present invention, 2#, 4# are carried out recruitment evaluation, and the effect that result and 3# obtain is similar.
Phosphatic type fodder acidulant by the inventive method preparation, add in the concentrate feed or premix that contains sodium bicarbonate, stone flour isogonic alkaline matter, can make phosphoric acid and external environment isolated, avoid effectively that the meta-alkalescence material directly contacts external in phosphoric acid and the feed, thereby avoid the two reaction to produce carbon dioxide or heat release, and avoid destroying other alkaline nutritional labeling in the feed, thereby improved the service efficiency of acidulant and feed.
Acidulant of the present invention efficiently is adsorbed in the refining carrier, and is covered by coating material, so this product is convenient to store.Stability is high in the use of this product, can efficiently bring into play the effect of acidulant, for animal provides the suitableeest digestive tract environment, reduces diarrhoea, promotes digestion, improves growth of animal performance and efficiency of feed utilization, is suitable for use of large-scale production.
