In the face of stressors, the intestine is not only an organ that is damaged, but also an organ that aggravates damage to the intestine and other tissues. Once the intestinal mucosal barrier function is damaged and the immune function is disordered, conditions will be created for bacteria and toxins to translocate and invade the body. The invasion of bacteria and toxins will lead to systemic multi-organ dysfunction. The consequence will be an imbalance of the internal environment of the body and the intestinal maintenance. Barriers and normal defenses become initiating a systemic inflammatory response.
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?
