The content of crude protein in cane shoots is as high as 12% to 13%, containing 16 kinds of amino acids and many kinds of sugars. In the state of winter storage, through anaerobic fermentation such as lactic acid bacteria, the sugar in the cane tip will be gradually transformed into organic acid (lactic acid). When the concentration reaches a certain concentration, the nutrients in the sugarcane shoot will be inhibited from being destroyed by other microorganisms. The sugarcane tip has been kept green, juicy, and nutritionally unchanged. Therefore, the winter storage cane tip is a good way to solve the lack of green feed for livestock in winter and early spring. Changdong City, Hunan Province, West Dongting Management District, planting 2,000 to 3,000 hectares of sugarcane every year, produce cane shoots from 35,000 to 40,000 tons, equivalent to 200 to 250 hectares of artificial high-quality grass, worth 3 million yuan. Before 2000, the cane farmers in West Dongting saw the sugarcane shoots as a major hazard and they took a burned approach. Since 2001, the West Dongting people have mastered the techniques of raising sugarcane stocks in winter storage by learning relevant scientific and technological knowledge. In winter, there are 20,000 cubic meters of sugarcane shoots for 3500 beef cattle, 554 buffaloes, 4,500 goats and tens of thousands of goose. A few rabbits eat for about 6 months. Their specific approach is: 1. Timely winter storage only fresh cane tip is only nutritious, containing large amounts of chlorophyll, amino acids, crude protein and sugar. After drying out, these nutrients can be destroyed and even converted to toxic substances that produce a large number of harmful bacteria, viruses and parasites. Therefore, you should choose before freezing, it is best before the frost, sugar cane tip when the green when the winter storage. 2. Preparation of Containers Since winter storage must create an oxygen-free environment to ensure the fermentation of anaerobic bacteria, the general requirements for winter storage containers are airtight, water-inhibiting, and easy to use gradually. Three types of containers are usually used: First, digging. To choose a high ground, the groundwater level is low, and dig pits where it is sunny. To dig into a rectangle, the depth is 100 to 150 cm, and the width is 60 to 80 cm. The length is not limited. The second is to build pools with concrete and red bricks. The third is to use abandoned houses. The ground and walls can be covered with agricultural film. In addition, you can also use plastic bags, large cylinders, large jars and other containers. 3. Cut the seal Press the seal to cut the cane tip of the winter storage into pieces about 1 cm long. Cut into the container. Do everything possible to press tight, the tighter the better. Finally covered with agricultural film, sealed with river sand or mud. Do not open before taking, so as not to damage the anaerobic environment. 4. Scientific use of winter storage can be opened after 50 to 60 days. Only one place can be opened and it can be gradually accessed in stages. If mildew is found after unsealing, mildew should be removed. If you find that the color is yellow-green, soft and juicy, and has a scent of alcohol, it is an excellent product. Can be directly used to feed cattle, sheep, rabbits, geese and other herbivorous livestock, poultry, can also add some fine feed. When starting feeding, it should be increased from small to large, and gradually increased; (Chang Long, Party Manager, West Dongting District, Changde City, Hunan Province)
