1. Arranging the best lambing season The production system for the fattening of the year when the lambs are produced will enable the slaughter of the lambs to reach the New Year's Day and the Spring Festival. This will yield considerable economic benefits. In this way, on the one hand, it meets the market demand, and on the other hand, it considers the changes in the supply of forage. In order for the lamb to have a longer growing period, the ideal lambing time should be in the early spring (January to February). In this way, the lamb's slaughter weight at the end of the year can reach about 35 kilograms, or even higher. Lamb lambing time should be relatively concentrated, which facilitates fattening management and facilitates the organization of sales to the city.
2. Choosing the right weaning time Lambs can be weaned at normal weaning time, ie 3 to 4 months of age. For large lambs, early weaning may be appropriate and delaying weaning time for weak lambs is appropriate. During the lactation period, efforts are made to develop the lambs because the fattening effect of the lambs is closely related to the time of weaning.
For the lambs weaned, those who did not castrated were castrated. Lambs are to be dewormed and medicinal baths, individually grouped in accordance with the principle of similar body weight and individual size, individually grazing, and individually supplemented and managed.
3. Choose ideal fattening time Lamb fattening ideal time should be selected in the autumn and autumn after the temperature is more appropriate. If the fattening period is too late, the weather will continue to consume cold, which will affect the effect of weight gain. At the same time, there are abundant forages in the autumn and sufficient agricultural and sideline products to provide feed guarantee for the fattening of lambs. In general, in mid-to-mid-October, mixed concentrates should be added. The start of fattening is too early and not good. In the case of too long fattening period, the total feeding period will be shortened, which will affect the lamb slaughter weight and the quality of the skin.
4. Ensure adequate grazing time Grazing should be performed every day for 7 to 9 hours to increase lamb feed intake and promote growth and development. After finishing the grazing cycle every day, the lambs should be supplemented with roughage. The sheep's gastrointestinal tract volume is relatively large. Even if a large amount of grass is eaten during the day, due to its strong digestive capacity, starvation may occur at night. After winter, the amount of roughage fed should be increased, and better quality roughage should be fed, such as peanut meal, sweet potato meal, etc.
5. Supplement feed The mixed feed is grazing on a daily basis and should be supplemented with mixed feeds. There are also two supplements in the morning and evening. Supplement feeds should be quantified and gradually increase with age. About 2 months before slaughter, it belongs to the phase of fattening and fattening. It should be used as the focus of supplementary feeding. The amount of mixed concentrate should be increased, and the amount of daily supplements should be 0.2-0.5 kg each. In the preparation of mixed feeds, salt and mineral elements should be added.
In order to increase the fatness of the slaughter sheep, it is necessary to increase the energy level of the feed at the end of the fattening period. Increasing the amount of corn in the mixed feed is a commonly used method. It is also possible to add oil to the mixed feed, such as adding cottonseed oil and rapeseed oil. When adding oil feet, the amount of oil should not be too much to prevent accumulation of toxic components in the body. If you do not want the sheep to be too fat and you want to reduce the weight of caraway flowers, you should control the energy level of the mixed feed during the late period of fattening to reduce the proportion of energy feed. Mixed feed formulation (for): corn 50%, bran 20%, barley 10%, bean cake 10%, cottonseed cake 9%, salt 0.5%, additive 0.5%.
Vitamins are a class of organic compounds necessary to maintain good health. This kind of substance is neither a raw material for body tissue nor a source of energy in the body, but a kind of regulating substance, which plays an important role in material metabolism. These substances are often supplied from food because they are not synthesized or are insufficiently synthesized in the body, although they are rarely needed.
Vitamins, also known as vitamins, are, in popular terms, substances that sustain life, are a class of organic substances necessary to maintain human life, and are also important active substances for maintaining human health. Vitamins are low in the body, but they are indispensable. Although the chemical structures and properties of various vitamins are different, they have the following in common:
1 vitamins are present in food in the form of provitamins;
2 vitamins do not constitute a component of body tissues and cells, it does not produce energy, its role is mainly involved in the regulation of the body's metabolism;
3 Most of the vitamins, the body can not be synthesized or the amount of synthesis is insufficient, can not meet the needs of the body, must be obtained through food;
4 The human body needs a small amount of vitamins. The daily dose is usually calculated in milligrams or micrograms, but once it is lacking, it will cause the corresponding Vitamin deficiency, which will cause damage to human health;
Vitamins are different from carbohydrates, fats and proteins. They are only a small percentage of natural foods, but they are necessary for the human body. Some vitamins such as B6.K can be synthesized by bacteria in the intestines of animals, and the amount of synthesis can meet the needs of animals. Animal cells can convert tryptophan into niacin (a type B vitamin), but the amount of production is not enough; vitamin C can be synthesized by other animals except primates and guinea pigs. Plants and most microorganisms can synthesize vitamins themselves, without having to be supplied from outside the body. Many vitamins are part of a prosthetic or coenzyme.
Vitamins are some small amounts of organic compounds necessary for human and animal nutrition and growth. They are extremely important for the metabolism, growth, development and health of the body. If you lack a certain vitamin for a long time, it will cause physiological dysfunction and cause certain diseases. Generally obtained from food. There are dozens of kinds found at this stage, such as Vitamin A, vitamin B, vitamin C and so on.
Vitamins are essential organic compounds in the metabolism of the human body. The human body is like an extremely complex chemical plant, constantly carrying out various biochemical reactions. The reaction is closely related to the catalytic action of the enzyme. Enzymes must be enzymatically active in order to produce activity. Many vitamins are known to be coenzymes of enzymes or constituent molecules of coenzymes. Therefore, vitamins are important substances for maintaining and regulating the normal metabolism of the body. It can be considered that the best vitamins are in the form of "biologically active substances" and are present in human tissues.
