Rabbits are herbivores and require a certain amount of fibrous food. China has a vast territory and abundant forestry resources. A large number of leaves, twigs and pomace can be used as a good feed and feed additive for rabbits. Any non-toxic leaves and twigs, as long as no odor, rabbits do not refuse to eat can be used as feed, such as the hedgehog leaves, pine needles, poplar leaves, eucalyptus leaves, mulberry leaves, willow leaves and so on. The leaves contain various nutrients such as cellulose, sugar, fat, protein, amino acids, and vitamins and minerals. According to the rabbit's different growth stages, adding suitable proportions in the diet can save the concentrate and improve the rabbit's production performance. . Fresh leaves have the highest nutritional value, followed by deciduous leaves and poor yellow leaves. Fresh leaves can be fed directly or after silage, so that rabbits can eat green feed year round. If deciduous and yellow leaves are fermented by microorganisms (micro-storage), their nutritional value can be improved.
Hedgehog leaf also known as artichoke. Fresh Locust Leaf contains 28.8% of dry matter, 5.33 MJ/kg of total energy, 7.8% of crude protein, 4.2% of crude fiber, 0.29% of calcium, and 0.03% of phosphorus. Vitamins and trace elements, its nutritional value is no less than legumes. Hedgehog leaves are used fresh and can also be made into Locust leaf powder. Feeding of Robinia pseudoacacia should be reasonable and should not be used alone for a long period of time. It needs to be matched with fine material and other green feed.
Pine needles are processed into pine needle powder for storage, transportation and use. If pine needle rosin phospholipids and tannins are removed during processing, the palatability is better. Pine needle powder processing method is very simple, the collected pine needles and twigs washed, dried, can be crushed. Pine needle powder contains 7% to 12% of protein, 18 amino acids such as lysine and aspartic acid, and total amino acids of 5.5%-8. l%; contains 7% to 12% of crude fat, 24% to 26% of crude fiber, and approximately 37% of nitrogen-free extract. The iron, manganese and other trace elements contained in pine needle powder are higher than the stems and leaves of herbs and legumes. Pine needle powder also contains a variety of vitamins, of which vitamin C and carotene content is the most prominent. Adding pine needle powder to the rabbit's diet can obviously promote the growth of rabbits, increase the hair production of long-haired rabbits, increase the number of litters of female rabbits and increase the survival rate of young rabbits. Fresh pine needles were added with water and boiled for 1 hour. Rabbits were fed pine needles once a day for 3 days to prevent and treat colds in rabbits.
