Every year from the winter season to the Spring Festival, lamb is listed in the peak season. The price of mutton is relatively high. Yangyang households can seize the favorable opportunity for long winter according to the individual conditions of the goat and adopt the scientific fattening method to round up the slaughter and obtain higher economic benefits.
Choosing good breeds is a good basis for raising sheep. It is optional to breed offspring of Boer goats, horse head goats, Saanen dairy goats, Nanjiang yellow goats and other local goats because of the high breeding rate, slaughter rate, and rapid growth rate of the hybrid goats.
Timely grazing of those ewes with poor fertility in time, and timely castration of lambs that are not used for breeding. All fattening sheep should be kept separately from other sheep, and divided into groups according to different ages, individuals, and parents. To ensure the best fattening effect of winter sheep.
Timely deworming First, levamisole can be used in combination with avermectin or ivermectin, or on sunny days 0.3% veterinary solution of dipterex or 12.5% ​​of double thymus gland 1:1000 times solution In the body, it removes 80% of the parasites inside and outside the sheep. Secondly, targeted drugs were used to repel certain parasites such as trematodes, cockroaches and cerebral lice. At the same time as deworming, prevention of epidemic diseases such as sheep dysentery, sheep aphthous disease, sheep pleuropneumonia, sheep epidemic disease, and sheep acne should be done to avoid affecting the fattening effect.
Prepare ready-made green grass Yangyang households must prepare enough fodder before winter, such as vines, stalks, leaves, alfalfa, etc., which can collect soybeans, sweet potatoes, radish and other crops and root and tuber vegetables, and also can prepare some silage corn stalks. Or dry straw for winter feed. In general, a sheep needs 3,000 kilograms of fodder for one winter.
Appropriate supplements for feeding and fattening can achieve the best slaughter effect. While ensuring that fattening sheep eat enough forage every day, they should also feed their appropriate amount of concentrated feed to ensure their nutritional needs. The diet should contain 60%-70% of roughage, that is, 30%-40% of hay, 30%-40% of straw, and 30%-40% of concentrated feed. Any sheep can freely feed and freely drink water. The reference formula for concentrate feed was corn 48.9%, soybean meal or cotton cake, 10% cake, 30% wheat bran rice bran, 10% distillers grains, 0.1% salt, and 1% additive. In general, each sheep feeds 100-150 grams of mixed concentrate on a day, and the concentrate can not be fed too much at a time to prevent the sheep from suffering from gastrointestinal diseases. The weight of the sheep can be increased by more than 200 grams by supplementing the improved hybrid sheep.
Timely slaughter The growth rate of adult sheep after a certain length of weight is greatly reduced. Continued fattening will not only increase costs, but also affect the quality of lamb. The fattening time of adult goats after castration is 30-40 days. The growth time of growing sheep and lambs can be appropriately extended. Generally, the growth and development of the goats within 6 months is fastest, and the feed reward is high, the input is small, and the yield is large.
Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries.
There is a conceptual overlap between plant extracts and herbal extracts. The raw materials of plant extracts in my country are mainly derived from Chinese herbal medicines, so domestic plant extracts can also be called Chinese medicine extracts to some extent.
