Problems solved by technology

[0006] The object of the invention of the present invention is: for above-mentioned existing problem, provide a kind of compound acidulant that is used to improve piglet feed digestibility and obtain piglet feed thereof, the present invention obtains a kind of compound acidulant by redesigning according to effective total acid content, The compound acidifier can release more hydrogen ions at pH=3.5, thereby effectively replenishing gastric acid, activating protease, and promoting protein digestion, overcoming the hydrogen ions released by traditional acidifiers at this pH value Too little to efficiently reach the defect of activating the protease

Embodiment 1

[0027] A compound acidifier for improving feed digestibility of piglets. In parts by weight, the compound acidifier consists of the following components: 5-10 parts of lactic acid, 40-60 parts of fumaric acid, 20-20 parts of anhydrous citric acid 40 copies and 10-20 copies of the carrier. Its preparation method comprises the following steps:

[0028] S1. Uniformly mixing 5 parts of lactic acid, 40 parts of fumaric acid and 20 parts of anhydrous citric acid to obtain an acid raw material mixture;

[0029] S2. Using γ-diphenylphosphinopropylsiloxane-platinum complex as a polymer catalyst, at a temperature of 30°C and a hydrogen pressure of 1-100 atmospheres, the reaction time is 3 hours until the degree of hydrogenation reaches 80 %-90%, get the first product;

[0030] S3. Adsorb the primary product with 10 parts of silicon dioxide (granular).

Embodiment 2

[0032] Example 2 is the same as Example 1, except that the compound acidifier consists of the following components: 8 parts of lactic acid, 50 parts of fumaric acid, 30 parts of anhydrous citric acid and 15 parts of carrier.

Embodiment 3

[0034]Example 3 is the same as Example 1, except that the compound acidifier consists of the following components: 7 parts of lactic acid, 50 parts of fumaric acid, 30 parts of anhydrous citric acid and 14 parts of carrier.

Abstract

The invention discloses a compound acidifier for improving digestive ability of piglet feed and the piglet feed obtained by the compound acidifier. The compound acidifier is prepared from the following components in parts by weight: 5-10 parts of lactic acid, 40-60 parts of fumaric acid, 20-40 parts of anhydrous citric acid and 10-20 parts of a carrier. The compound acidifier is obtained through redesign according to the effective total acid content, and the compound acidifier can release more hydrogen ions when the pH value is 3.5, so that gastric acid can be effectively supplemented, the effects of activating proteogen and promoting protein digestion are achieved, and the defect that the proteogen cannot be activated effectively due to the fact that the hydrogen ions released by a traditional acidifying agent are too few under the pH value is overcome; and meanwhile, fumaric acid, citric acid and lactic acid are compounded, so that the purpose of better activating the proteogen can be achieved, and the obtained compound acidifier is good in palatability, does not affect feed intake, has a component proportion which is simple and easy to control, and is high in comprehensive cost performance and very suitable for being used as an additive of the piglet feed.

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed, in particular to a compound acidifier for improving piglet feed digestibility and the piglet feed obtained therefrom. Background technique [0002] The digestion of protein in the feed first needs the digestion of pepsin, and the source of protease and the precursor protease, the activation of protease needs enough hydrogen ions. During the weaning stage of piglets, due to the imperfect development of their own intestines, the stomach secretes gastric acid. The ability is very limited. Before the age of 60 days, it is difficult for piglets to rely on the gastric acid secreted by their own stomach to control the pH value of the stomach below 3.5. At the same time, the feed is changed from breast milk to feed, and the exogenous feed will consume some gastric acid. At this time, the gastric acid is even more insufficient, and pepsinogen cannot be fully activated, thereby affecting the ...
