Jerusalem artichoke is a perennial herb. It has the characteristics of cold resistance, drought resistance, tramp resistance, strong adaptability, and low requirements for cultivation and management conditions. It can be planted in front of and behind the house or on unused land. The yield is generally 2500 to 3000 kilograms of stems per mu, and about 2500 kilograms of fresh stems and leaves, which can be harvested for several years once planted. Helianthus tuberosus is generally digging holes and planting in spring, 50 kg to 75 kg per mu, row spacing 0.5 m, plant spacing 20 to 30 cm, hole depth 10 cm, base fertilizer per hole is about 1 […]

In recent years, due to the development of dairy cattle and shed-raising sheep and other breeding industries, straw micro-storage feed has been widely promoted and applied, and good economic and social benefits have been achieved. The operation technology of straw micro-storage feed is summarized as follows. The straw micro-storage feed uses straw, corn straw, wheat straw, corn and other crop stalks as raw materials, and is added with a high-efficiency composite dry inoculant prepared by bioengineering technology by lignocellulosic bacteria and organic acid fermentation bacteria. In an anaerobic environment, it decomposes cellulose and lignin and converts them into sugars, which are converted into lactic acid and volatile fatty acids by

In early spring, if the feed is yellow and green, feeding adult rabbits with thatch roots, willow buds, and elm seeds is good for aphrodisiac; feeding long-haired rabbits with rosewood buds is good for the growth of rabbit hair; for suckling female rabbits feeding more bitter vegetables, dandelions, bittersweet, pulling rice seedlings, etc. will help promote milk. In order to increase disease resistance, a certain amount of green onions and garlic should be mixed into the feed during wet and rainy seasons. Summer is hot and humid, and rabbits are prone to diarrhea. At this time, it is best to feed some "dry grass" with low water content, such as

According to the growth stages of pigs, it can be divided into five stages: suckling pigs, piglets, middle pigs, large pigs, and breeding pigs. Each stage should adopt a different pig feed making formula to prepare and use pig feed. 1. Preparation of suckling pig feed (1) Features　 Suckling pig refers to a growing pig from birth to weaning. The growth and development of suckling pigs are relatively rapid, and it is obviously not enough to rely on breast milk for nutrition. At this time, supplement feeding should be timely to maintain weight. (2) Feed preparation standards Corn 44.6%, fish meal 4%, soybean protein concentrate 5.5%, puffed soybean 31.5%, plasma

(1) Requirements for feed making raw materials It is prohibited to add drugs and other substances that are directly or potentially harmful to animals and humans in feed and drinking water; it is prohibited to add meat and bone meal, fish meal, bone glue and other animal-derived raw materials (milk and dairy products) to feed Except), and all kinds of feed processed with these raw materials; it is forbidden to add melamine, cyanuric acid and melamine-containing scraps in the feed. (2) Feed hygiene requirements The used concentrate supplements, concentrated feed, etc. must meet the feed hygiene standards; prevent the forage from being contaminated by the feces of farmed animals and

1. Fish Pellet feed The diameter of pelleted fish feed is usually 2.5～8.0 mm and the length is 5～10 mm, which can be directly fed. If the feed is damp, do not feed it directly, dry it or dry it before feeding it; if the feed has deteriorated, it should not be fed again to prevent fish poisoning after eating. 2. Fish Cake feed The cake feed should be crushed, soaked, and grinded to feed small fish. Feed the medium to large fish to soak them. 3. Fish Grain feed Big grains such as corn should be processed and crushed and fed to fish; small grains, such as grains, can

What are the most common grass and fodder for raising sheep in rural areas? Raising sheep in rural areas is not like raising sheep professionally and does not need to plant professional forage. Raising sheep in rural areas is the use of weed resources and crop scraps that are unique in rural areas as forage and fodder. In the green grass season, grazing is all-weather, and in the dry season, grazing is half-grazing, half-eating dry forage, that is, agricultural waste. 1. Spring, summer and autumn are mainly grazing. Raising sheep in rural areas, in early spring, that is, before the Qingming Festival, most weeds are in the budding stage, and

Screw shells are leftovers of rural aquatic products. The shell left after people eat screws, mussel shells, etc., is mainly composed of calcium carbonate and organic bone calcium compounds. The screw shell is mechanically pulverized into powder, and after puffing and high temperature treatment during feed processing, most of the calcium is degraded into soluble or slightly soluble in water under the action of the digestive juice in the animal body, which can be used by the animal The digestive system absorbs and utilizes to supplement the animal's nutritional needs for calcium elements. It is an ideal calcium supplement for various breeding animals. It is economical and affordable, convenient to

Although this type of additive does not contain the nutrients needed by chickens, it is beneficial to promote layer chicken growth, increase egg production, enhance disease resistance and layer chicken feed storage. Its types include antibiotic additives, insect repellent health care additives, antioxidants, antifungal agents, Chinese herbal medicine additives and hormones, enzyme preparations, etc.　 1. Antibiotic additives Antibiotics have antibacterial effects. Some antibiotics can inhibit the activity of harmful bacteria in the intestines of chickens when added to the diet as additives. They can resist a variety of respiratory and digestive diseases, improve feed utilization, and promote weight gain and egg production. The effect is more obvious when the chicken

The use of compound feed to raise pigs can increase the utilization rate of pig feed and achieve the effect of rapid growth and slaughter. In this regard, many large-scale pig farms have achieved successful experience. So, how can large-scale pig farms make use of local feed resources and conditions to make compound feeds themselves? Generally speaking, consider the following five principles: (1) Variety diversity A single feed cannot meet the nutritional needs of pigs. When selecting, choose as many raw materials as possible. The compound feed for pigs is preferably composed of more than 6 raw materials. The main energy feeds include corn, rice bran, bran, dried sweet potatoes,

Adding 10-20mg of soy isoflavones per kilogram of diet for broiler chickens can improve the meat color, water content and pH of the broiler chicken, prevent muscle oxidation during storage, delay the rapid decline of muscle pH after slaughter, and prevent poor-quality meat produce. Adding 600-2700mg betaine per kilogram of diet for broilers can increase the content of creatine, creatinine, inosinic acid and other flavor precursors and myoglobin in the chicken, and improve the flavor and color of the chicken. Adding 50-100 mg of L-carnitine per kilogram of diet can increase the redness value, inosinic acid and crude fat content of breast muscles, and improve the color and flavor of

1. Natural pasture. There are mainly Gramineae, Leguminosae, Compositae, Cyperaceae, Chenopodiaceae, etc. It is more appropriate to harvest forages during booting, budding, and first flowers, because the forages are in a period of vigorous growth, young and juicy, and high in protein content, which can reach more than 15% based on dry matter. Such forage grass is tender, contains less crude fiber and lignin, has good palatability, is easy to digest, and has high nutritional value. It contains a variety of vitamins, phosphorus and calcium, and the yield of grass is also high. Especially natural forage grass has fast lignification and decreased digestibility. The older the forage grass is, although
