Embodiment 1

[0038] According to the weight ratio of lactic acid:citric acid:malic acid:tartaric acid:bamboo vinegar=40:20:20:20:160, the feed acidifier is prepared after uniform mixing.

[0039] 60 weaned piglets were taken, with an average initial weight of about 5.4kg. The 60 weaned piglets were randomly divided into a control group and a compound acidifier group according to the principle of similarity in litter, sex, age, and body weight. The control group was fed with conventional antibiotic-containing diets (the addition of chlortetracycline, colistin sulfate and kitastamycin were 75, 20 and 50 mg / kg basal diet respectively); the compound acidifier group (without antibiotics) was The feed acidifier was prepared by adding 0.65% by weight of the above-mentioned method in the feed for suckling piglets, that is, the addition amount was 6.5 kg / t of the basic diet. The test period is 25 days, and the specific test process is the same as test 1. The test results are shown in Table 4.

Embodiment 2

[0043] According to the weight ratio of lactic acid: citric acid: malic acid: tartaric acid: phosphoric acid: bamboo vinegar = 30: 10: 20: 15: 25: 160, the feed acidifier is prepared after uniform mixing.

[0044] Experimental animals and design are the same as in Example 1. The compound acidifier group (without adding antibiotics) was prepared by adding 0.65% by weight of feed acidifier to the piglet feed by the above method, that is, the addition amount was 6.5 kg / t of basal ration. The test results are shown in Table 5.

[0045]

[0046] The test results showed that adding the compound acidifier increased the daily gain of piglets by 17.4%, feed intake by 11.8%, feed-to-weight ratio by 4.6%, and the incidence of diarrhea from 12.3 to 2.9%.

Embodiment 3

[0048] According to the weight ratio of lactic acid: citric acid: malic acid: tartaric acid: phosphoric acid: bamboo vinegar = 20:20:10:15:35:160, the feed acidifier is prepared after uniform mixing.

[0049] Experimental animals and design are the same as in Example 1. The compound acidifier group (without adding antibiotics) was prepared by adding 0.65% by weight of feed acidifier to the piglet feed by the above method, that is, the addition amount was 6.5 kg / t of basal ration. The test results are shown in Table 6.

[0050]

[0051] The test results showed that the daily gain of piglets increased by 14.1%, the feed intake by 7.2%, the ratio of feed to weight decreased by 5.9%, and the incidence of diarrhea decreased from 12.3 to 3.2%.

Abstract

The invention belongs to the field of fodder, and specially relates to a fodder acidulant, which is characterized by comprising the following raw materials in part by weight: 20-40 parts of lactic acid, 10-20 parts of citric acid, 10-20 parts of malic acid, 10-20 parts of tartrate, and 150-180 parts of bamboo vinegar liquid. The invention also provides an application method of the fodder acidulant, and the method specially is that the acidulant is added in an amount of 2-10 Kg per ton of fodder. The invention utilizes bamboo vinegar liquid combined with organic acid and inorganic acid to produce fodder composite acidulant which can reduce the acid-binding capacity of the fodder, substitute or partly substitute antibiotics. In addition, the composite fodder acidulant can perform opsonization for feeding pig intestines and inhibit the growth of pathogenic bacteria, has effective effect in solving problems of intestinal diseases and diarrhoea in pigs production, can promote health conditions of pigs, and improve production performance of pigs.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a feed acidifier and a using method thereof. Background technique [0002] As we all know, piglet breeding is the basis for the development of pig production, and cultivating high-quality piglets is the key to improving the quality of pig herds, reducing production costs, and improving the economic benefits of pig production. Due to the special physiological characteristics of underdeveloped digestive organs and incomplete digestive function of piglets, coupled with nutritional and environmental stresses, piglets directly lead to problems such as frequent intestinal diseases, diarrhea, growth retardation, and high mortality. Therefore, enteric diseases are an important factor in piglet mortality. In actual production, high-dose antibiotics and high-dose zinc oxide are commonly used to treat piglet diarrhea, resulting in more and more serious bacterial resistance and serious envir...
