Heat stress generally refers to the physiological response of the animal body's non-specific defense response to heat stress sources. When the ambient temperature exceeds the upper critical temperature of the thermal neutral zone, the heat generated by the body exceeds the heat dissipated to the surrounding environment, causing the energy originally used for growth and development to be used to maintain the body's homeostasis, and exhibits a series of symptoms. A non-specific physiological response, this phenomenon is called heat stress.
The core of the harm caused by stress to animals is that stress causes intestinal microecological disorders and the proliferation of harmful bacteria, leading to the release of large amounts of bacterial endotoxins, destroying the intestinal mucosal barrier, causing a large amount of endotoxins to invade the blood, and destroying the body's immune function.
Summer is here, the environment is hot and humid, and chicken coccidiosis is most likely to occur at this time. Coccidiosis is a common intestinal disease of chickens caused by Eimeria coccidia infection. It occurs in different breeds, ages and seasons. Especially for high-quality chicken breeds with relatively rough breeding environments, coccidia is an unavoidable topic.
The liver transfer period of P. vannamei is the most important period in breeding. It promotes better liver transfer of P. vannamei, improves the survival rate of P. vannamei, ensures body health, and ensures greater profits!
As we all know, the normal egg is generally oval, the egg shape index is between 1.32-1.42 (egg shape index = the long axis of the egg/the short axis of the egg) is the best, and the surface is smooth and full, and the egg produced by the chicken of the same age is moderate in size and uniform. However, malformed eggs often appear in production, and the so-called malformed eggs are eggs that are not full and irregular in shape. Deformed eggs are various, common are: no shell eggs, thin shell eggs, wrinkled shell eggs, how are these deformed eggs formed?
Breeding friends often say that the use of enteritis drugs such as colistin and neomycin is not effective in treating diarrhea and feed passage enteritis. In fact, the diarrhea and diarrhea we usually talk about are just a description of the symptoms of enteritis and do not represent the cause of enteritis. There are many causes of enteritis.
The broiler industry plays an important role in meeting the growing global demand for meat. Broilers are raised for their efficient meat production, which is particularly important in countries with low food self-sufficiency. Ensuring the gut health of broilers and their overall health is critical to animal welfare and industry profitability. One of the most pressing problem in poultry production is still the intestinal health, had a profound impact on poultry intestinal health.
