Swine enzootic pneumonia causes great harm, and these prevention and control measures must be kept firmly in mind
Swine enzootic pneumonia is a serious swine infectious disease with high morbidity and low mortality that drives up costs and reduces profits in the pig industry. In China, for slaughter pigs of the same 100 kg, pigs infected with this disease suffer a loss of 119 yuan more than uninfected ones. Infection with Mycoplasma alone rarely causes death in pigs, but when other bacteria are also involved, it leads to a long course of disease, difficult treatment, reduced production levels, and possibly a certain mortality rate. Mycoplasma hyopneumoniae is present in the lungs of 80-90% of pigs, and more than 90

Garlic current management details reminder: don't overlook these key points
According to relevant information, during this current period the growth of all parts of the garlic plant is at its greatest, so this period is also the critical period for water and fertilizer needs of the garlic plant. This is especially true for nitrogen and potassium fertilizers; at this time, a deficiency of nitrogen or potassium will cause extremely large losses in yield. Another report indicates that the maximum leaf width and pseudostem diameter (leaf sheath) of garlic show a significant positive correlation with the weight of garlic scapes and garlic bulbs. To obtain high yields of garlic bulbs and garlic scapes, plants with thick, sturdy leaf sheaths and wide leaves must be cultivated, so ensuring that the garlic is not harmed by diseases and pests is also a guarantee

How are wild Schizothorax prenanti domesticated? Keep the precautions firmly in mind
Schizothorax prenanti belongs to the Cyprinidae family, Schizothoracinae subfamily, and Schizothorax genus; it is also known as Yayu, fine-scaled fish, and carp. As market demand for Schizothorax prenanti increases, its natural resources fall short of demand. To meet the market need for Schizothorax prenanti, some areas in Sichuan and Chongqing have begun flow-through pond and cage culture. Schizothorax prenanti farming has developed fairly quickly in recent years, and its broodstock mostly comes from wild populations in natural waters. In order to scientifically and rationally protect and develop high-quality wild fish resources, the Make River Sichuan-Shaanxi Taimen Protection

Oyster mushroom management reminder: special attention must be paid to cooling at present
Oyster mushrooms are mainly produced in winter, and most have now entered the second and third flush stages. At this time, great attention must be paid to cooling. The reasons: first, the natural temperature in spring is suitable for oyster mushroom growth, so people tend to neglect controlling the temperature inside the shed and of the mushroom bags; second, mycelial vitality declines, and high temperatures accelerate mycelial aging; third, in spring oyster mushrooms fruit quickly and evenly, and the respiratory heat produced can cause the temperature of the mushroom bags to rise sharply in a short time; fourth, to prevent a major outbreak of yellow mushroom disease, which occurs easily above 20°C. According to our investigation, yellow mushroom disease has recently shown early signs, and yellow

How to store lilies? Keep these key points in mind
Lilies can be stored by the burial method or by the basket (box) storage method. The specific steps are: 1. Pre-cooling: before storage, the lilies need to be spread evenly on the ground to air-dry, so as to dissipate heat. When air-drying, the pile height should be about 2-3 bulb-heights. The air-drying time should not be too long, to prevent the scales from discoloring. After pre-cooling, the bulbs should be selected promptly and stored without delay. 2. Bulb selection: choose lily bulbs that are white in color, large, fresh, round and neat in shape, with plump scales, without fibrous roots, without loose or scattered scales, and with brown scales

There's a right way to feed rabbits: keep these three dos and three don'ts in mind
Feed a complete mixed ration. The nutrient composition of a rabbit's daily ration is: 10% crude protein and 10% crude fiber, 5% fat, 2800 kcal of digestible energy per kilogram of ration, and 10% amino acids. If there is no way to feed a complete mixed feed, appropriately add concentrated feeds such as soybeans, soybean cake, wheat bran and corn, along with succulent feeds such as carrots. Feed heavily at night. Rabbits have a strong tendency to eat at night, and nighttime intake can account for more than 75% of their total daily intake. Therefore, provide rabbits with enough feed and drinking water at night. Change feed gradually. When one kind of feed has been fed for a long time, the rabbit has

Releasing fish fry in early spring requires care; keep these precautions in mind
Fish fry quality For fish fry of the same species and same age, the specifications should be uniform, with little difference in body length and body weight, thick back muscles, bright color, intact scales and fin rays, normal activity, and strong upstream-swimming ability. After being taken out of the water and placed in a basin, the gill covers should not open, the tail should not bend, and the fish should keep jumping, with no wounds or parasites on the body surface. Fish fry disinfection Some farmers do not disinfect fish fry at all when releasing them, resulting in a high disease rate, and drug treatment is not ideal. In fact, as long as fish fry disinfection is done well, disease prevention can often achieve twice the result with half the effort

What are the precautions for feeding pigs with distillers' grains? Farmers should keep them in mind
Distillers' grains are divided into baijiu distillers' grains and beer distillers' grains. Baijiu distillers' grains have 32 percent dry matter, 3.36 MJ per kg digestible energy, and 7.5 percent crude protein. Beer distillers' grains have 14 percent dry matter, 1.43 MJ per kg digestible energy, and 3.6 percent crude protein. Whether baijiu distillers' grains or beer distillers' grains, they must be fed fresh; if piled up for a long time, they will become moldy and spoiled. If there is any left over, it can be put into a large vat, trampled down firmly, and soaked in water. Pregnant sows and lactating sows are not suitable for feeding, to prevent miscarriage, stillbirth, and so on. For meat pigs, it generally does not exceed the daily ration

How to manage cotton in the late stage? Nine reminders to keep in mind
Cotton has now entered the boll-opening stage, the final growth stage. Throughout September, the upper bolls are still continuing to grow and fill out. From now until harvest is completed in late October, there are still more than 50 days, and if management is relaxed, significant losses can still occur. (1) Do not relax mentally when it comes to late-stage management, and especially do not think that because there are not many bolls, high yields are impossible, and therefore be unwilling to invest further. If you can keep more than 40,000 bolls per mu and let them grow and open well, you can harvest four to five hundred jin of seed cotton per mu. I downloaded 6 new nationally approved cotton varieties from our province

How to manage a rabbit farm? Keep these 4 key points in mind
1. Vigorously tackle disease prevention and control: In addition to controlling infectious diseases through preventive injections, coccidiosis in particular, which occurs mostly in spring, has a very high mortality rate and poses a great threat to rabbit farms. We should persist in combining prevention and treatment, with prevention as the priority. Veterinary drugs such as Qiu Ke can be mixed into the feed, and the whole farm can be sprayed once every 10 days with Baidusha, which can control the occurrence of coccidiosis. 2. Do a good job in rabbit breeding: Does have a short reproductive cycle and a high kindling rate, and breeding is highly technical and meticulous work. Timely mating and regular breeding should be carried out to improve the survival rate of young rabbits. 3. Seed
