Rex rabbit fattening is the final stage in rabbit production, aimed at producing high-quality meat and pelts. This phase should begin after the rabbits have completed their skeletal growth to ensure optimal muscle and fat development. Proper management during this period is crucial for maximizing productivity and profitability. Here are some key practices for successful Rex rabbit fattening:
First, once the skeleton has fully developed, weight gain during fattening primarily comes from muscle and fat. Therefore, a diet rich in concentrates should be used as the main feed. It's especially beneficial to include feeds high in sugars such as sweet potatoes, potatoes, hawthorn, and radishes. These ingredients help increase energy intake and promote fat deposition. Green feeds should also be included in moderation to maintain digestive health and provide essential nutrients.
Second, physical activity should be limited during the fattening period to reduce energy expenditure and conserve feed. Rabbits can be housed in higher densities in a warm, dimly lit environment, which helps promote fat accumulation. However, care must be taken to avoid overcrowding that could lead to stress or disease outbreaks.
Third, castrating male rabbits before the fattening stage can significantly improve meat quality and reduce feed costs. Castration lowers metabolic rate and reduces oxidation, making it easier for the rabbit to store fat. Studies show that castrated males can gain 10% to 15% more weight than uncastrated ones under similar feeding conditions.
Fourth, water intake should be carefully managed. As the diet shifts from mainly green feed to concentrate-based feed, rabbits need plenty of clean, fresh water. Ensure they have access to water 2 to 3 times daily to support digestion and overall health.
Lastly, maintaining good hygiene is essential during this period. High stocking density, limited light, and reduced movement can weaken the rabbits’ immune systems, making them more prone to illness. Regular cleaning of cages, proper waste management, and ensuring clean food and water sources are critical to preventing disease outbreaks.
By following these practices, farmers can optimize the growth and health of their Rex rabbits, resulting in better meat quality, higher yields, and improved economic returns.
