Sika deer is a national first-class animal protection, not only has great ornamental value, but also has extremely high antler, deer kidney, deer tail, deer muscle, deer, deer blood, deer skin, deer tendon, deer heart, and venison. Medicinal, edible and economic value. Since 2000, our county began to introduce deer for domestication. It has been more than 10 years since then. Sika deer breeding has become an effective way to get rich. Now in the winter, the deer do not breed in the winter, but it is closely related to the velvet and calving of the following year. In the winter, if there is no good feeding and management condition, there will be no summer high yield. Therefore, it is an important part of raising the economic benefits of deer conservation and ensuring safe and successful wintering. Winter feed preparation: Corn stalk or green storage: 50%-55% Concentrate: 20% of soybean meal Wheat bran about 20% Salt: adult male deer 30-40g/day Adult doe 20-25g/day Deer 10-20g/day Urea: no more than 3% of concentrate A small amount of auxin and oxytetracycline Bone meal and other calcium-containing feed: 1%-3% Mix all ingredients with appropriate amount of warm water and stir until the hands do not have water and do not scatter. If too much water is added to the ingredients, the deer feed will be reduced. Too little water is not conducive to the digestion and absorption of nutrients by the deer. To prevent symptoms such as vitamin deficiency in spotted deer, it is advisable to add appropriate amounts of feed, such as lotus root starch, carrots or beets, to meet the deer's growth and nutrients required for metabolism. In addition, the rational choice of venues for the deer farms directly affects the development and management quality of the deer farms, and to a large extent determines the economic benefits of the deer farms. Deer likes to inhabit quiet and secluded places. The terrain of the deer field should be a relatively flat topography with a slight slope to the south or southeast, which facilitates drainage and keeps the field dry. To avoid the noisy and polluted environment, it is best to build a sandy loam soil that is sheltered from wind, sunny, conducive to drainage, solid soil, good water permeability, and no pollution. The deer farm should have enough land area and a long-term reliable feed base. There must be sufficient water in the deer farms, with good water quality and no pollution. The deer farm should not only keep away from noise but also have convenient transportation to ensure timely supply of feed and other materials. The deer field should be kept away from cattle and sheep pens to reduce the incidence of epidemics. There are two ways for paper sizing, one is in front of the sheet forming (beating or ingredients) add sizing agent in pulp called intracytoplasmic sizing, another is in sheet forming after coating on paper or cardboard surface is called the surface glue.The sizing agent of pulp is mainly rosin sizing agent, synthetic sizing agent, paraffin sizing agent and neutral sizing agent.Surface sizing agent and neutral sizing agent.Surface sizing is mainly to improve the smoothness of the surface of the paper, reduce the porosity and prevent the surface hair and hair loss.The more used is modified and unmodified starch, and the PVA is also used.Other products include paraffin emulsion, animal glue, carboxymethyl cellulose, polyurethane, styrene-maleic anhydride copolymer, acrylate copolymer, dihydroxy fatty acid compound, etc. Paper Sizing Agent,Sizing Agent For Paper,Paper Surface Sizing Agent,Papermaking AKD Surface Sizing Agent Shandong Tiancheng Chemical Co., Ltd. , https://www.tianchengchemical.com
