Description

Balancing liquid for regulating gastric acid of ruminant and preparation method thereof Technical Field The invention belongs to the technical field of ruminant feed additives, and relates to a balancing solution for regulating gastric acid of ruminants and a preparation method thereof. Background The stable pH value of the rumen environment of ruminant animals (such as cattle) is critical to the digestion, absorption, growth and development of the ruminant animals, and acidosis is easy to be caused when gastric acid in the rumen is excessive, so that the feed intake of the ruminant animals is reduced, digestion is disturbed, and the culture benefit is seriously influenced. Currently, the main current method for regulating gastric acid of ruminants in the industry is to use sodium bicarbonate (sodium bicarbonate), and the pH value in the rumen is neutralized by adding sodium bicarbonate into concentrate or allowing the ruminants to eat freely, so that the aim of avoiding acidosis is fulfilled. The baking soda has obvious technical defects that firstly, the baking soda has great damage to the intestines and stomach of ruminants, the normal growth of the ruminants is influenced after long-term or improper use, secondly, the feeding mode is difficult to control, if the ruminants are not allowed to eat freely, the stomach acid cannot be neutralized in time when serious, acidosis is easy to cause, if the amount of the free ingestion is too large, the gastric alkali of the ruminants is caused, the digestion function of the ruminants is disturbed, and the growth is adversely affected. In order to thoroughly overcome the technical bottlenecks of gastrointestinal injury caused by strong alkalinity, feeding difficulty caused by response lag and the like of baking soda in practical application, the invention introduces a novel sodium humate buffer. Unlike simple acid-base neutralization with sodium bicarbonate, sodium humate is synergistic to block malignant circulation of rumen acidosis through four core mechanisms of physical adsorption, chemical buffering, microbial regulation and mucous membrane protection, and stabilizes rumen pH and function. The specific chemical buffer mechanism is more key to accurate regulation, because humic acid is organic weak acid, sodium humate is sodium salt, when rumen pH is too low, HA is balanced according to reactionH++AThe system spontaneously moves to the left to consume excessive H + so as to directly neutralize excessive lactic acid and volatile acid (VFA), and a large amount of carboxyl (-COOH) and phenolic hydroxyl (-OH) contained in sodium humate molecules can realize bidirectional pH stabilization through high-efficiency H +、Na+ exchange capacity. Therefore, research and development of a gastric acid regulating product which can accurately regulate the rumen pH value of ruminants, has no gastrointestinal damage and is easy to control the addition amount becomes a technical problem to be solved in the ruminant cultivation field.
