Good sheep breeds have large size, fast growth, high reproduction rate, strong adaptability, good meat quality, and high efficiency. At present, there are mainly Boer goats, Sha Neng goats and Huang Huai goats. Most of the goats raised by farmers nowadays are dominated by local breeds. Their individuality is small, their growth is slow, and their slaughter rate is low, so the benefit is not high. In order to reverse this situation, Boer goats and Sha Neng goats should be introduced for crossbreeding. For example, a cross between a Boer Goat and a local goat is nearly 10 kg heavier than a local goat at 6 months of age, which can significantly increase the benefits.
Second, the scale of raising sheep should be appropriate.
The scale of family raising of sheep should be measured by force. It can be determined according to the number of cultivated land, the size of pasture, the amount of forage and feed, the labor force and the amount of funds invested. Generally, the scale of professional breeding households is 15 to 25 breeding ewes.
Third, reform the traditional feeding habits.
1. The remixed group grazing is a single group grazing. For the lambs, single-group grazing is performed according to physiological characteristics and life characteristics. The extensive management is carefully managed and the early cultivation is strengthened so that the lambs can eat good milk, early weaning, early grass feeding, and early feeding to speed up their growth and development.
2. Change simple grazing to grazing and feeding. In winter and spring withered grasses, it is difficult for herds to satisfy their nutritional needs by grazing alone. Therefore, half-day grazing and half-day supplementary feeding are conducted in winter and spring, which can not only save the sheep from physical exertion, but also achieve the purpose of conservation.
3. Change the production of spring lamb to produce winter lamb. Lambs are born in winter. Lambs grow for 10 to 11 months in the same year, which is very beneficial to the winter slaughter in the autumn of fattening in the autumn. This can avoid the wintering of the flock, save manpower and material resources, accelerate the turnover of sheep, and increase economic efficiency. .
4. Extensive feeding management for fine feeding management. First of all, we must do a good job of seasonal grazing, autumn weather is cool, the nutritional value of paraquat seeds is high, is the golden season of grazing, then we must try to grazing as much as possible, so that sheep eat more grass; winter cold weather, grazing as little as possible, to achieve the right amount of exercise Yes, to add quality hay and fine ingredients; spring weather is cold and changeable, let the sheep run less to eat; hot summer weather, more mosquitoes, catch as soon as possible as soon as possible to graze. Secondly, to make full use of the farm-produced green concentrate feeds, especially lambs, pregnant ewes, and rams, grazing alone can not meet their nutritional needs, so be sure to add concentrate and forage, with particular attention to protein Supplies of minerals and vitamins. Third, pay attention to providing clean drinking water and improve environmental hygiene. Clean the sheep house every day and clean the feed trough and sink to ensure that the sheep house is cool in winter and cool in summer.
Fourth, regular insecticide and medicine bath.
During the breeding process, sheep are highly susceptible to both parasites on the inside and outside of the body, resulting in slow growth, low resistance, and serious death. Therefore, the sheep farmers should conduct deworming and medicinal baths every year according to the parasite prevalence. Usually the first insect repellent in the spring, and more with levamisole or insect nemesis, etc. drive nematodes, every 5 to 7 days, and then necrophagous nematodes 1 times, and then again in autumn. The medicinal bath is conducted once a year in spring and autumn, and the weather is selected to be warm and sunny. The water temperature is 35° C., and 0.5 to 2% of trichlorfon is used for adding sulfur for 1 to 2 minutes.
Fifth, do a good job in disease prevention and control.
Lamb dysentery, streptococcal disease, brucellosis, No. 5 disease, infectious pyrematitis, etc., are serious diseases that are harmful to sheep. Vaccination and comprehensive prevention and control work should be done well, and strict immunization should be established and implemented. program.
Goji berry for people on the commodity Goji berry, plants Ningxia Goji berry, Chinese Goji berry and other Goji berry species collectively. People often eat medicinal medlar mostly Ningxia medlar fruit "medlar", and Ningxia medlar is the only load "2010 edition of Chinese Pharmacopoeia" varieties.
Ningxia Goji berry cultivated area in China the largest. Ningxia Goji berry are mainly distributed in northwestern China, while in other areas common Chinese Goji berry and its variants.
If "Goji berry" refers to the commodity "Goji berry", the basic is derived from Ningxia Goji berry dry and ripe fruit; if "Goji berry" refers to the wild Goji berry plants other than the northwest region, the basic plant Goji berry or Goji berry .
Ningxia Goji berry shrub, or cultivation of large shrubs due to artificial pruning, 0.8-2 meters high, cultivators stem diameter up to 10-20 cm; branches finely, when wild more and slightly ramp up or bow bow, when cultivated Twig bow song and the crown mostly round, with vertical ribbing, gray or gray, glabrous and slightly shiny, with no short leaves spines and leaves, flowers, long thorns. Leaves alternate or clustered, lanceolate or oblong-lanceolate, apically short acuminate or acute, base cuneate, 2-3 cm long, 4-6 mm wide, up to 12 cm long, 1.5-2 cm wide , Slightly fleshy, veins not obvious.
Main Ingredients: medlar contains betaine, atropine, gyoscyamine.
Lycium barbarum polysaccharide: Lycium barbarum polysaccharide is a water-soluble polysaccharide, is the most important active ingredient of Chinese Goji berry, the relative molecular mass of 68-200, becoming a hot research at home and abroad. Which in order to LBP immune regulation and anti-tumor effect of the most. There are many studies have shown that LBP has the role of promoting immunity, anti-aging, anti-tumor, free radical scavenging, anti-fatigue, anti-radiation, liver protection, reproductive function protection and improvement.
Betaine: The chemical name is 1-carboxy-N, N, N-trimethylaminoethyl lactone. It is chemically similar to amino acids and belongs to quaternary ammonium bases. Betaine is one of the major alkaloids in goji berries, leaves and stalks. Goji berry on lipid metabolism or the role of anti-fatty liver is mainly due to the betaine contained in it in the body as a methyl donor role. Research on Lycium betaine is limited to the domestic determination of the content, the extraction process and the physiological role of Lycium barbarum plant (enhanced salt tolerance) research, the pharmacological effects of Lycium betaine little research.
Lycium pigment: Lycium pigment is present in the Goji berries of various types of color material, is an important physiological active ingredient of Goji berries. Mainly include - carotene, lutein and other colored materials. Lycium contains the carotenoids have a very important medicinal value. Many studies have proved that Goji berry seed pigment has the function of improving human immune function, preventing and inhibiting tumor and preventing atherosclerosis. Carotene is the main active ingredient of lycopene pigment, with antioxidant and vitamin A as a precursor of synthesis and other important physiological functions.
Pharmacological effects: have an impact on immune function.
Taste: Goji berry: sweet, flat. Goji leaves: bitter, sweet; cool.
