At what age can Sutai sows start mating?
Abstract When Sutai sows grow to about 6-7 months old, they can be mated for the first time. Usually at this time their body weight has reached about 70 kg. Sutai sows have an estrous period of about 20 days, and one estrus lasts about 4 days.

Usually at this time their body weight is about 70 kg. Sutai sows usually have an estrous cycle of 20.3 days, and the duration is 3.95 days. Getting Sutai sows successfully mated usually takes some effort, and the following matters need attention:</p><p>1. Carry out cleaning and disinfection. Usually, before mating, in order to prevent the sow's uterus from being infected by bacteria, Sutai sows need to be disinfected at this time. Tap water can be used to clean the sow. Usually after cleaning, a disinfectant is used for disinfection. A relatively low-concentration potassium permanganate solution can be used as the disinfectant, and then a towel is used to wipe the sow clean.</p><p></p><p>2. When a Sutai sow is in the standing estrus stage, a boar can be brought over to mate with the sow. This can stimulate the sow and arouse desire. The time is generally limited to half an hour.</p><p>3. If artificial insemination is adopted, it is best to have professional technicians carry it out, because this is a relatively complicated process. Not only must a suitable insemination catheter be selected, but some lubricating oil must also be chosen so as not to make the sow uncomfortable. The catheter needs to be pushed very slowly into the Sutai sow's body, with an angle of 45 degrees upward and advanced 5 cm, and finally injected horizontally. The time is best controlled at about 5 minutes.</p><p></p><p>From the introduction above, do you now understand the mating time for Sutai sows? During the mating period of Sutai sows, it is a very delicate process. Doing it well means profit; if any step goes wrong, it may lead to some losses.</p>

Key Technical Points and Methods of Raising Chickens with Distiller's Grains
Abstract The main technology of raising chickens with distiller's grains is the preparation of distiller's grains. The materials for fermenting distiller's grains include corn flour, tofu residue, swill, coarse bran, etc. The bacterial liquid and materials are fermented at a ratio of 1:200. After thorough stirring, they are placed in a sterilized container. After sealing, it is placed in a place without sunlight.

What are the precautions for raising chickens in winter? Farmers should master them in advance
Abstract The most important thing in raising chickens in winter is to pay attention to keeping warm. Chickens are poultry that are very afraid of the cold, so a heater needs to be placed in the chicken coop, and drafty openings should be plugged. On sunny days, take the flock outside to bask in the sun; ultraviolet rays can sterilize and improve their own resistance. Pay attention to dehumidifying during cold waves. In the chicken coop, you can place

Spring Chicken Raising Management Methods and Technical Key Points
Abstract Moisture-proofing: During the plum rain season, the chicken coop must be kept dry. A dehumidifier specially designed for chicken farms can be purchased, which can greatly reduce the humidity level in the chicken shed. Manure: Spring is prone to breeding bacteria, so chicken manure must be cleaned up in time. Feed: Some immunity-boosting nutritional feed can be added to the chickens' feed to strengthen their resistance. Ventilation: Bacteria easily breed in a stuffy, damp environment, so the chicken shed needs proper ventilation, but this should not be done on rainy days, otherwise the damp air outside can easily come in.

How to ventilate a pig-farming greenhouse? These methods are simple and practical
Abstract A ventilation outlet can be made at the top of the greenhouse, which can effectively discharge the stale air inside. Some old-style greenhouses are relatively low, so the ventilation outlet needs to be opened larger to be effective; open the greenhouse for a period of time every day to let natural air in. When the temperature inside the greenhouse
