The use of leaves for fodder has a long history in China. The classical literature "Shen Nong's Materia Medica" has records of "Tong Ye feeding pigs, hypertrophy three times, and easy to raise". China is rich in tree resources. The leaves are rich in protein, minerals and vitamins. More than 100 species of tree leaves can be used as feed; the development and use of leaves for feeding livestock and poultry, low cost, rapid weight gain, provincial concentrate, and high efficiency , And help to improve resistance to disease. The leaves can be freshly fed, or they can be harvested and then stored in pots and cylinders. After dried and crushed, they can also be fed in winter and spring withered grass. Eucalyptus leaves and leaves contained 20.82% of crude protein, 2.7% of crude fat, 19.48% of crude fiber, 31.69% of nitrogen-free extracts, 3.79% of calcium, 0.03% of phosphorus, 0.96% of lysine, and more The vitamins, especially carotene and vitamin E2, are abundant; the protein content of 2 kilograms of loquat leaves is equivalent to 1 kilogram of bean cake. Adding 10-15% of eucalyptus leaf powder to pig feed can replace fishmeal feed. Adding 5% of eucalyptus leaf powder to chicken feed can increase egg production rate and increase egg yellow pigment. Pine needles are the leaves of pine trees and are not only nutritious (250 mg of pine carotene, 1.2 g of calcium, 320 mg of iron, and mineral elements such as copper, zinc, and cobalt per kilogram of pine needle), but also contain phytoncide, which can promote livestock and poultry. Growth, increase product rate, prevent gastrointestinal diseases and various vitamin deficiencies, and have the effect of increasing the amount of semen secretion for broilers. According to the experiment, adding 6% pine needle powder to the chicken diet can increase the egg production rate by 13-15%. Adding 4% pine needle powder to the diet of the boar can increase the sperm extraction volume 8-10. %. Paulownia leaves Paulownia leaf meal contains 19.32% crude protein, 11.11% crude fiber, 5.8% crude fat, 54.83% nitrogen-free extract, 0.2% phosphorus, and 1.93% calcium. The paulownia leaves are used as feed. In addition to providing nutrients, there are also functions such as promoting the growth of livestock and poultry, accelerating weight gain, and increasing the production of laying hens. According to experiments, weaned piglets weighing 6-8 kg, add 30 grams of paulownia leaf powder each day, and feed 2 months, 24% more weight than the control group; 25-30 kg of shelf pigs, every other day feeding 60 grams of paulownia leaf powder was fed for 1 month, and the average weight per head increased by 14% compared with the control group. According to other data, adding 5% of Paulownia leaf meal instead of wheat bran in the diet of chicken can increase egg production by 1.3%, egg weight by 1.7%, and feed cost by 10%. Apple leaves The apple leaves have a wide source and high nutritional value (including protein 9.8%, fat 7%, crude fiber 8%, calcium 0.29%, phosphorus 0.13%, ash content 10%, and nitrogen-free extract 59.8%). It is a good feed for rabbits. The leaves of the willow willow leaves contain 11.1% crude protein, 2.11% crude fat, 11.66% crude fiber, 54.13% nitrogen-free extract, 0.57% calcium, 0.08% phosphorus and many Amino acids have a higher content of main nutrients than ordinary forages. Their crude fiber content is lower than that of ordinary pastures and their palatability is good. They can be directly beaten and fed to pigs, and they can also be crushed and fed to pigs after fermentation. Mulberry Mulberry is a good feed for chickens. Foreign studies have found that the broilers given 4 weeks before the larvae feed 3% of the mulberry leaf powder in the feed. Compared with broilers without mulberry leaves, the broilers have a finer meat, a stronger aroma and a particularly good taste, and can reduce the number of hen houses. Odor. In addition, the leaves of pear, peach, poplar, eucalyptus, persimmon, citrus, grape, amorpha, apricot, plum, etc., can be used to feed livestock and poultry after proper treatment. It should be noted that the contents of nutrients in the leaves collected at different periods vary greatly. The tender fresh leaves generally collected in spring have good palatability and high nutritional value. The young leaves in summer are followed by autumn leaves.
