Factors that cause diarrhea in pigs and chickens

The main substitute - wheat, the DON content is generally too high to cause necrotizing enteritis. What is even more frightening is that after testing, it was found that the content of mycotoxins in many feed materials such as corn and wheat exceeded the standard. Intestinal inflammation can also easily induce the occurrence of necrotizing enteritis.

Since the beginning of this year, the prices of many breeds have continued to be sluggish, and they have entered a long period of deep losses.

Therefore, in order to optimize feed costs and reduce losses, many companies use more complex raw materials, lower nutrient concentrations, and fewer functional additives, or in the selection of functional additives, especially those aimed at improving intestinal health, pay too much attention to processing costs , while ignoring the functionality of the product itself.

For example, in the selection and use of probiotics, probiotic products on the market are uneven, and their functionality is even more different. How to evaluate the effect of probiotics is very important. As one of the core products of current feed substitution, probiotics should be comprehensively evaluated. The first thing to do is to evaluate the bactericidal effect of probiotics (see figure below).

It is necessary to clearly compare the inhibitory ability of different probiotics against pathogenic bacteria through tests in vitro and in animals.

Secondly, probiotics must have stable environmental resistance performance, such as the effects of high temperature granulation in feed production, gastric acid, choline and other physical and chemical conditions in livestock and poultry on probiotics.

Compatibility with other anticoccidial agents, acidulants and other additives is also evaluated. This ensures that probiotics have a stable and efficient effect in animals.

The relaxation of biosecurity is also a central factor in causing diarrhea. At present, the continuous losses of multiple animal species at the breeding end, especially yellow chickens and woolly pigs, have entered a deep loss. As a result, in order to save costs, terminal farms have carried out a large number of layoffs, reduced the dosage of additives and vaccines, and relaxed biosecurity management, making livestock and poultry more likely to cause diarrhea.
