Causes of disease of farmed young rabbits after weaning
After weaning, young rabbits are faced with changes in environment and feed, and the stress response caused by these changes is an important reason for the disease of young rabbits after weaning.
The main results are as follows: 1. Under environmental stress, the young rabbits are moved to the new environment. The physiological function of weaned rabbits is not perfect, the immune function and self-resistance of weaned rabbits are weak, and their adaptability to the new environment is low. 2. Under nutritional stress, the young rabbits were changed from breast milk to food. The content of immunoglobulin in colostrum of female rabbit is high, and newborn rabbits can obtain passive immunity by absorbing immunoglobulin in colostrum. With the decrease of breast milk feeding and immunoglobulin, and the increase of feed intake, young rabbits mainly rely on active immunity. The development and function of gastrointestinal mucosa of one-month-old rabbits are not perfect. when the gastrointestinal function is normal, the beneficial and harmful microorganisms in the intestines are in a state of mutual restriction and balance, so that the baby rabbits do not get sick. When the young rabbits were weaned, the antibody level of the young rabbits was greatly reduced, the immune function was inhibited, the structure of digestive organs was destroyed, the digestive function was reduced, the resistance of the young rabbits was reduced, and the indigestion was caused. The pathogenic bacteria that originally existed in the intestinal tract take the opportunity to multiply and produce toxicity, leading to diarrhea.
Before and after weaning, intestinal mucosal repair factor, immune synergist, coated Vc and enzyme preparation should be added to the diet to improve the stress resistance and immune function of weaned rabbits.
