Problems solved by technology

According to the survey, there are great differences in the typical domestic piglet rations. Most piglets are not in the optimal requirement for animal production, and the rations have high acid resistance and low electrolyte balance, which is consistent with the optimal acid resistance of animals. (low acidity) and electrolyte balance value (high electrolyte balance value) are contradictory, which will inevitably affect the growth potential of animals
In addition, many experiments have shown that when too much acidulant is added to the diet, it will affect the balance of its electrolytes. Conversely, when too much electrolyte (baking soda) is added to the diet, it will also affect the acidity of the diet and the acidity and alkalinity in the animal body. balance

Abstract

The invention relates to a pig starter ration acidity and electrolyte balance coupling regulate and control method, which weights 100g pig starter ration with electrolyte balance value and positions it into a cleaning beaker; it adds some basic sodium salt so that the electrolyte balance value comes to the best product working value (250mEq / kg); it adds 200ml deionized water and some muriatic acid to adjust the acid; it dose uniform mixing and uses acidifier with known density to titrate it after mixing half an hour with the titration end pHú¢4.00; at last the consumed acid value is the needed value of the starter ration acidity.

Description

technical field [0001] The invention relates to a method for regulating and controlling animal nutrition, in particular to a method for coupling and regulating the acidity and electrolyte balance of piglet diets. Background technique [0002] Dietary acidification and adjustment of electrolyte balance can greatly improve the performance of piglets, which is of great significance to production. According to the survey, there are great differences in the typical domestic piglet rations. Most piglets are not in the optimal requirement for animal production, and the rations have high acid resistance and low electrolyte balance, which is consistent with the optimal acid resistance of animals. (low system acidity) and electrolyte balance value (high electrolyte balance value) are contradictory, which will certainly affect the performance of animal growth potential. In addition, many experiments have shown that when too much acidulant is added to the diet, it will affect the balan...
