After the felling and tending of the Pinus tabulaeformis forest, a large amount of pine needles remain after thinning. Most of the pine needles are abandoned in the mountains for decay, which not only harms the forest environment, but also is a great waste. In fact, pine needles are an invaluable resource. With simple processing, pine needles can be produced. It is of great practical significance to change the structure of livestock feed and promote the development of animal husbandry. First, the nutritional value of pine needles feed Pine needle pine needles on the determination of the chemical composition of pine needles containing 18 kinds of amino acids, more than 10 kinds of trace elements, antibiotics and carotenoids, including crude fiber about 27 %, Containing carotene per kilogram
