(1) Keeping up with the market needs to adjust the diet formula
The quantity and grade of beef required by major cities are different. For example, beef noodles in Beijing, grilled beef steak in Shanghai, and beef and glutinous raw materials in Guangzhou all require fine beef. The breeding experts generally believe that the marble texture of beef is good. beef. Therefore, the proportion of concentrate in the diet can be increased from 40% to 75% or even higher. If the fattening period is extended from 90 days to 140 days, it is also required to raise technology.
(2) Make full use of feed
Cottonseed cake (粕), rapeseed cake (粕), distiller's grains, sugar residue, sugar cane tail, beet pulp, peel, etc., is the energy and protein feed of fat cattle, the diet can be increased from 5% to 15%, corn, etc. The proportion of grain feed can be reduced, which also reduces the cost of feeding.
(3) The necessity of straw processing
Straw must be found in the diet of cattle, which is an essential component of normal digestion of cattle. Feeding straw must pay attention to the following two factors: First, the proportion of concentrate in the diet during the post-fertilization period increases. If a certain amount of straw is not maintained, the digestion of the cattle will be abnormal, causing rumen stagnation, gastric nipple wear, and cattle stopping eating and dying. And so on. There should also be 2% to 3% of straw in the beef quality improvement diet. In order to make the cattle eat more straw, keep the straw clean, remove the dust, and make the straw soft, and the straw should not be broken into powder. Straw is short, 5-7 cm is good, straw, wheat straw, corn stalk can be used to achieve the purpose with a masher. Second, it is necessary to produce high-quality beef with a marble texture and red and white, which is inseparable from corn stalks and other feeds. Green hay or hay can not replace the effect of straw, otherwise it will affect the fat color and reduce the price of meat.
(4) Straw processing technology
Feeding with processed straw can increase the feed intake of cattle and improve the nutrition of cattle. There are several processing methods: one is cleaning, the straw is soaked for a short time, the dust is removed by light, and the straw is softened. The main raw materials are wheat straw and straw; the second is softening and softening, mainly corn coarse straw; The salt water is moistened, the straw is poured, mixed and pressed with 1% warm salt water, covered with plastic cloth, and fed after 1 day; the fourth is ammoniated, the straw is treated with water dissolved in urea, and the protein can be improved after feeding. The content can be promoted when the urea price is low.
Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
