Forage-use green probiotic acidifier and preparation method thereof

Abstract

The invention discloses a forage-use green probiotic acidifier. The forage-use green probiotic acidifier is prepared from the following components in mass percent: 0-5% of 60% phosphoric acid solid powder, 28-60% of 35% lactic acid solid powder, 3-14% of 60% n-butyric acid solid powder, 30-45% of solid organic acid, 0-6% of disodium hydrogen phosphate, 0-13% of calcium formate, 0-10% of prebiotics and 0-6% of filling carriers. According to the invention, the disodium hydrogen phosphate and an organic acid or an inorganic acid (citric acid or phosphoric acid or the like) are added to the forage-use green probiotic acidifier to form a buffer pair, so that the buffering capacity of the acidifier is enhanced to sustainably maintain pH to be about 3-4 in a gastric phase, feed change or weaning stress is effectively perfected, and the growth of harmful bacteria in an intestinal phase is inhibited.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a green probiotic acidifier for feed and a preparation method thereof. Background technique [0002] Modern intensive farming focuses on production efficiency, and high-energy, high-protein diets are the main means of pursuing high efficiency. Due to the immature development of the digestive tract of young livestock and poultry, the secretion of digestive enzymes and gastric acid is insufficient, and the ability to digest nutrients is poor. Therefore, the intake of a large amount of high-nutrient concentration diets will inevitably lead to indigestion, causing flatulence in the front part of the digestive tract, and regurgitation Phenomenon. At the same time, the accumulation and fermentation of a large amount of high-concentration undigested nutrients in the hindgut lead to an imbalance of intestinal flora, which in turn leads to indigestion. As time goes on, pathogenic ...

AI Technical Summary

Problems solved by technology

Three of the formulations are mainly phosphoric acid (30-60%), lactic acid (20-40%) and calcium lactate (30%). However, our research found that phosphoric acid is a medium-strong acid with Strong corrosiveness, the addition of a high proportion will lead to a rapid decrease in the pH value of the stomach of livestock and poultry, causing acidosis; while acidifiers based on lactic acid (organic acid) and calcium lactate (organic acid calcium salt) have poor pH adjustment ability, Cannot effectively reduce the acid binding force of the feed in the stomach, and the price is high

[0006] Therefore, the use of inorganic acids, organic acids or organic acid salts alone cannot meet the needs of effectively reducing the acidity and production costs of feed systems

In addition, the suitable adsorption ratio of liquid acid and adsorbent (expanded grade silica) was not clearly defined in previous inventions.

Due to the inherent volatility and strong hygroscopicity of the acidifier, it is easy to cause the loss of effective content in the process of adsorption and drying, and it is difficult to ensure the quality of the finished product
