Pine needle powder contains 11% to 12% crude protein, 9% to 11% crude fat, 1% to 1.5% calcium, 0.05% to 0.1% phosphorus, 1000 to 1300 mg chlorophyll, 300 to 400 mg carotene, and 500 to 600 vitamins. It contains 18 kinds of amino acids and 7 kinds of trace elements, among which the content of selenium is more, which can prevent white rickets, white muscle disease and vitamin deficiency caused by selenium deficiency. Adding 3% to 5% pine needle powder to the compound feed, the average daily gain per pig is increased by 15% to 20%, so that the fattening pig can shorten the feeding cycle for 20 to 30 days, and improve the pork quality and lean meat rate. Increase by 3% to 5%.
As a feed additive, pine needle powder is not easy to form harmful residues in edible animal products due to its non-toxic side effects. It is easy to widely promote and use, and it is more and more affected by farmers in the current trend of returning to nature and pursuing green food and healthy consumption. Our favor. However, due to the addition of 5% to 10% of pine needle powder in the feed, the amount is large, which not only increases the cost of the product, wastes the drug, but also affects the palatability and nutritional ratio of the feed. When the feed is first, the livestock will appear. The phenomenon of reduced intake and the like, and the active ingredients of pine needle powder itself are unstable and inconsistent, it is difficult to play a balanced role in promoting growth. In the practice of breeding, pine needle infusion instead of pine needle powder was added to the full-price feed to feed the pigs and achieved good results. Pine needles and their production and use method are: using pine needles as raw materials, crushing, cooking, pressing, filtering, sedimentation and separation to obtain pine needles. Each meal is fed with 1.5~2.0 ml of this pine needle into the feed, and the pig is fed 2 to 3 meals a day. The pig will eat the pine needle and the feed will grow faster, generally 3 to 7 days will be effective. The total required amount per head is only about 500 ml, which is not only easy to use, but also reliable in quality and effective in effect.
