There are two points to be grasped in the selection of grass species: First, it is necessary to purchase good varieties from reputable units. At present, there are many types of grass seed in the market, and there are many different types of grass. Some unscrupulous traders shoddy to make many farmers deceived. The introduction of the best to the animal husbandry sector, the agricultural research department and the formal grass company to buy, must not be willing to buy cheap seeds, so as not to achieve the expected results after planting, affecting production. The second is based on the digestive characteristics of geese, select suitable forage species. Goats suitable for raising geese include ryegrass, Rumex, and grain pods.
(B) Pay attention to determining the area for forage cultivation based on the number of geese
Under normal circumstances, 0.5 to 15,000 kilograms of fresh grass can be produced per 0.067 hectare. During the fattening period of meat geese by 80 days, then 100-150 hectares of forage geese can be planted in 0.067 hectares. However, in the production practice, the climate and the field management level all affect the yield of forage grass. In addition, due to the market price of meat and goose, the slaughter time is also an uncertain factor. Therefore, the planting area of ​​pasture in production should be slightly higher than the theoretical plan. And pay attention to ensure that the period of utilization of pasture is consistent with the time of hatching, so as to avoid the use of pasture when the goslings are introduced or hatched.
(3) Pay attention to the feeding of pre- and post-fattening
Goslings have poor early digestive function, rapid growth and development, and they need to supplement feeds that are easily digestible and full-fledged, and feed the pellets better. Supplementation should be carried out in the order of the first material and then the green material to prevent goslings from picking up green material. With the increase of the age of the geese, the green feed can be fed gradually and the concentrate can be reduced. After 30 days or so, supplements can be stopped and fed mainly for pasture. However, feed supplements should be added about 20 days before slaughter to increase geese.
Catalyst refers to a substance which can change the reaction speed in a chemical reaction and whose composition and mass remain unchanged after the reaction. The catalysts that speed up the reaction are called Positive Cata-lyst and the slower ones are called Negative Cata LYST or moderators. Generally speaking, the catalyst is to correct the catalyst. These catalysts are widely used in industry, especially in organic chemical industry. They are of great significance, for example, catalysts are needed for the preparation of sulfuric acid by contact method, the hydrolysis of synthetic ammonia, esters and polysaccharides, and the hydrogenation of oils and fats. Commonly used catalysts are metals, metal oxides and inorganic acids. If the catalyst is a solid, the reactant is a gas, forming a heterogeneous catalytic reaction, this catalyst, sometimes called a catalyst or contact agent.
Auxiliaries refer to the industrial and agricultural production, especially chemical production, in order to improve the production process, improve product quality and output, or give the product a unique application performance, usually need to add some auxiliary chemicals. It is a kind of important auxiliary raw materials in chemical production, which can give the products special properties and improve the use of finished products, accelerate the chemical reaction speed and improve the yield of products, save raw materials and improve the processing efficiency. It is widely used in chemical industry, especially in organic synthesis, synthetic material processing and petroleum refining, pesticides, pharmaceuticals, dyes, coatings and other industrial sectors. By use, it can be divided into synthetic auxiliaries and processing auxiliaries. Auxiliaries used in the synthesis and polymerization of resins, fibers, rubber and other monomers are called synthetic auxiliaries, including catalysts, initiators, solvents, dispersants, emulsifiers, polymerization inhibitors, regulators, terminators, etc. Auxiliary chemicals used in the manufacture of rubber, plastic products and in the spinning and spinning of chemical fibers are called processing aids, including plasticizers, heat stabilizers, antioxidants, light stabilizers, flame retardants, foaming agents, lubricants, demoulding agents, vulcanizing agents, accelerators, softeners, anti-scorching agents. Agents, surfactants, oils, fillers and so on. Many of these Additives are dangerous chemicals, such as diphenyl peroxide, azodiisobutyronitrile, hydrogen peroxide-ferrous blue, alkyl aluminum, titanium chloride and other initiators, catalysts are inflammable and explosive materials, should be stored and transported in accordance with the relevant provisions of the Regulations on the Safety Management of Chemical Hazardous Goods. Management and use.
