The medicinal rabbits, a newly developed breed successfully cultivated in China, serve multiple purposes such as medicinal, experimental, cosmetic, and meat production. These rabbits have become a valuable resource for extracting various drugs and vaccines from their living bodies. Their meat is not only delicious but also nutritious, free from pollutants, and considered a healthy food source. Additionally, their skin is known for its beauty-enhancing properties, helping to delay aging, improve health, and prevent cardiovascular and cerebrovascular diseases, making them highly sought after by consumers both domestically and internationally. With their ability to thrive on roughage, fast growth, high reproduction rates, and significant economic returns, these rabbits have long been exported to Japan and are expected to have a promising market.
The breeding techniques for medicinal rabbits include several key steps:
First, nursing does and their newborns should be placed in farrowing boxes with soft hay or cotton. If the mother fails to pull out her fur, it's necessary to assist her by removing the hair around her abdomen and placing her in the box. When giving birth, it's best to stay nearby and offer warm, light salt water (0.5–1%) immediately after birth to help the young drink and nurse. If there are too many kits, they can be grouped together, and the mother’s urine can be used to mark the fostered kits to prevent rejection. In some cases, a syringe with a bicycle valve core can be used to feed milk or goat’s milk to weak babies. By day 20, the puppies can be introduced to easily digestible, high-quality mixed concentrates.
Second, weaning should be gradual. Starting at 30–35 days old, reduce breastfeeding and introduce soft feeds. Feed small amounts more frequently—six times a day—and add antibiotics like olaquindox to boost disease resistance.
Third, young rabbits aged 18–20 days begin shedding their soft fur and grow rapidly. The diet should include 15% soybean cake, 25% corn, 15% wheat bran, 30% peanut meal, 10% peanut cake, 0.5% salt, and 4.5% premix, processed into pellets. Offer 30–50 grams daily with free access to water.
Fourth, for rabbits aged 3–5 months, the formula includes 14% soybean cake, 20% corn, 17% bran, 11% peanut cake, 30% peanut meal, 4% sorghum, 0.5% salt, and 3.5% premix. Daily feed is 60–100 grams with unlimited water.
Fifth, for breeding rabbits (5–6 months), males and females should be kept separate to avoid early mating. The feed consists of 8% bean cake, 19% corn, 18% wheat bran, 40% peanut meal, 5% sorghum, 6% peanut cake, 0.5% salt, and 3.5% premix. Daily feeding is 80–120 grams.
Sixth, adult rabbits (7–8 months) weighing about 5 kg are ready for breeding. During estrus, they should be paired. Keep the cage temperature between 5–10°C in winter. Ten days before breeding, supplement with vitamin E tablets. The feed formula includes 15% soybean cake, 4% premix, 10% peanut cake, 31% peanut meal, 20% corn, 19% wheat bran, and 1% salt, with 100–150 grams per day.
Seventh, male rabbits aged 7–8 months can follow the adult diet during non-breeding periods. During breeding, use a formula of 15% bean cake, 10% peanut cake, 35% peanut meal, 15% corn, 20% wheat bran, 1% salt, and 4% premix. Provide 100–180 grams daily along with plenty of water.
Eighth, pregnant does require a protein-rich diet. Avoid spoiled or frozen feed, and ensure a calm environment to prevent stress-induced miscarriage. The diet includes 15% soybean cake, 4% premix, 10% peanut cake, 31% peanut meal, 20% corn, 19% wheat bran, and 1% salt, with 110–200 grams per day.
Finally, for export, live medicinal rabbits must meet Japanese import standards: they should be healthy, disease-free, clean, white-brown in color, and weigh between 2.65 kg and 2.75 kg. They must remain standing for at least 24 hours before being shipped.
Rubber is a high elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under the action of a small external force. It can recover its original state after the removal of external force. Rubber is a completely amorphous polymer with a low glass transition temperature (T G) and a high molecular weight of more than several hundred thousand.
Rubber is divided into natural rubber and synthetic rubber two kinds. Natural rubber is made from rubber tree, rubber grass and other plants after extraction and processing. Synthetic rubber is made by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.
