Analysis of the reasons why young rabbits are prone to disease after weaning

After weaning, young rabbits face changes in environment and feed, and the stress responses caused by these changes are an important reason why young rabbits become ill after weaning.

1. Environmental stress: young rabbits are moved to a new environment and do not adapt. The physiological functions of weaned young rabbits are still not fully developed, and their immune function and stress resistance are weak, so their adaptability to the new environment is low. 2. Nutritional stress: young rabbits change from nursing to eating feed. The colostrum of doe rabbits is high in immunoglobulin, and newborn young rabbits obtain passive immunity by absorbing immunoglobulin from colostrum. As the amount of breast milk fed and the immunoglobulin in it decrease, while feed intake increases, young rabbits then rely mainly on active immunity. In young rabbits around one month old, the development and function of the gastrointestinal mucosa are incomplete. When gastrointestinal function is normal, beneficial and harmful microorganisms in the intestine are in a mutually restrictive state, maintaining balance, so the young rabbits do not become ill. When young rabbits are weaned, the antibody level of the young rabbits is greatly reduced, immune function is inhibited, and so on, which damages the structure of the digestive organs, reduces digestive function, and lowers the resistance of the young rabbits, leading to indigestion, allowing pathogenic bacteria originally present in the intestine to seize the opportunity to multiply in large numbers and produce toxicity, resulting in diarrhea.

Before and after weaning of young rabbits, intestinal mucosal repair factors, immune synergists, coated Vc, enzyme preparations, etc. should be added to the diet to improve the stress resistance and immune function of weaned young rabbits and help them pass through the weaning stage smoothly.
