Long haired rabbits have unique digestive characteristics due to their developed digestive system.
(1) High digestibility of crude fibers:
The long haired rabbit is a single stomach herbivorous animal, with a long and complex digestive tract and a large volume. It relies on the microorganisms in the cecum and developed balloon tissue to effectively utilize low-quality and high fiber feed.
According to experiments, providing an appropriate amount of coarse fiber feed in the diet of long haired rabbits is beneficial and harmless to their health, can stimulate intestinal peristalsis, and promote normal digestion and absorption functions. On the contrary, if the crude fiber content in the diet is too low, it can cause slow intestinal peristalsis, prolonged retention time of the content, fermentation deterioration, and induce the proliferation of harmful bacteria, leading to enteritis, diarrhea, and even death.
(2) Can fully utilize the protein in coarse feed:
According to experiments, long haired rabbits not only have a high digestibility of protein in green coarse feed, but also have strong digestion and utilization ability for protein in low-quality feed.
(3) Can tolerate high calcium content in the diet:
Long haired rabbits do not have strict requirements for the proportion of calcium and phosphorus in their diet as other livestock and poultry. Experiments have shown that the phosphorus content in the diet of long haired rabbits should not be too high. Only when the ratio of calcium to phosphorus is below 2:1 can high levels of phosphorus be tolerated, and excessive phosphorus is excreted from the body through feces and urine. If the phosphorus content in the diet is too high (exceeding 1%), it will also reduce the palatability of the feed and affect the feed intake of long haired rabbits.
Rabbit hair has a certain growth period. When rabbit hair grows to the end of maturity, the bottom of the hair root gradually becomes thinner and falls off, and new hair begins to grow. This process of hair exchange is called rabbit hair exchange. Age related hair exchange refers to young rabbits.
When a rabbit is born, it is hairless and usually begins to grow fine hair at 45 days old. By around 30 days old, all the milk hair has grown. For young rabbits with normal growth and development, the first age related hair change is at 30100 days old, and the second age related hair change is at 130190 days old. The hair changing pattern after 6.57.5 months of age is the same as that of adult rabbits.
Seasonal hair change: Seasonal hair change refers to adult rabbits. Under normal circumstances, adult rabbits change their fur once a year in spring and autumn. Spring hair exchange takes place in April. Due to the abundant feed and vigorous metabolism at this time, rabbit hair grows faster and the hair exchange period is shorter; Autumn hair exchange takes place in August. Due to changes in feed, the metabolic function of hair follicles is weakened, resulting in slower growth of rabbit hair and a longer hair exchange period.
Pathological hair loss: During the illness or for a long period of time, long haired rabbits suffer from insufficient nutrition, metabolic disorders, and skin metabolic disorders, often leading to systemic or local hair loss, which is called pathological hair loss.
