Porcine sub-health syndrome
In the actual production management of pig farms, managers and technicians generally pay more attention to the treatment and prevention of diseases, but do not pay enough attention to chronic consumptive diseases such as pig parasites. in the production practice for many years, we have found that: in addition to the above factors, the pig sub-health syndrome in the critical state between health and disease is relatively long now and in the future. And virulent virus disease will become the biggest enemy of the pig industry. If the pig farm manager does not pay high attention, it will be serious.

Do a good job of preventing heat and cooling chickens in summer
The most suitable temperature for laying hens is 17 ℃ ~ 28 ℃, and the temperature that has little effect on production is about 7 ℃ ~ 27 ℃. When the summer temperature in Shandong Province is more than 35 ℃, chickens will faint and die when they reach 40 ℃. The experiment proved that when the temperature in the henhouse reached more than 30 ℃, the sperm of the rooster decreased, the sexual maturity of the hen was delayed, the fertilization rate decreased by 60%, and the laying rate of laying hens decreased generally. At the same time, due to the decrease of blood calcium and the imbalance of acid-base balance, it was easy to induce other diseases, such as Escherichia coli, mycosis and so on. Broilers are easy to fat because of their large size.

How to give a pig an injection
Injecting pigs is the main method to prevent and treat pig diseases. Several injection methods are usually used, such as intramuscular injection, subcutaneous injection, intravenous injection, intraperitoneal injection and so on. Intramuscular injection is rich in blood vessels, and the injected solution is absorbed quickly. in addition, the distribution of sensory nerves in muscle is less, and the pain caused by intramuscular injection is less, so it is the most commonly used method of injection. The injection site is generally chosen in the muscular buttocks or neck. When injecting, first shearing, disinfecting, holding the syringe in the right hand, piercing the needle vertically. The depth can be determined according to the size of the pig.

Symptoms and comprehensive prevention and treatment of porcine endometritis
When sows are in breeding, artificial insemination, delivery, midwifery and abortion, if they do not pay attention to hygiene or disinfection is not strict, bacteria will be brought into the uterus, resulting in reproductive infection of sows, including Escherichia coli, Corynebacterium, Streptococcus, Staphylococcus, Pseudomonas aeruginosa, Proteus and so on, leading to endometritis. During delivery, the operation of the birth canal or part of the placenta remains in the uterus, which can also cause endometritis. Bacteria can also enter through the vulva when the floor of the barracks is poorly sanitary, or when sows are active in a sewerage playground.

Matters needing attention in raising piglets in spring and summer
First, pay attention to the change of temperature. The temperature changes greatly in spring and summer, Rain Water is more, the temperature is larger. Pigs like dry environment, how much fat tissue, piglets are easy to be afraid of cold. Therefore, the temperature in the house and the dry environment of the house should be maintained. Second, pay attention to the increase of protein feed. Especially for piglets after long-distance transportation, some piglets suffer from diarrhea and diarrhea, loss of appetite and weight loss due to wind chills and bumps in cars and boats. in addition to doing a good job in drying and keeping warm in the barn, nutrition should be replenished in time.

The male goose is castrated and fattened.
Except for a small number of male geese raised by the rural people according to the traditional feeding method, most of them are fattened and sold as meat geese. This old feeding method has the advantages of long feeding time, slow growth and development and low breeding efficiency. If the male goose is castrated and then fattened, not only the goose is docile and easy to manage, but also grows fast, has a large size and has high economic benefits. In order to further improve the breeding efficiency of goose farmers, the castration methods of male geese are introduced as follows: 1. Castration season

Raise growing pigs well in summer and autumn
Piglets are weaned at the age of 3-6 weeks and kept in weaning houses for 4 weeks. When the body weight is 20-50 kg, they are called growing pigs because of the rapid growth of bones and muscles. At this stage, the protein level is 16% and the lysine content is 0.8%. A large amount of adipose tissue is deposited at 50-110 kg, so the levels of protein and lysine can be appropriately reduced to 14% and 0.65%, respectively. General pig farmers are used to using feed concentrate or premix with corn, wheat bran and other raw materials, but it should be noted that the quality of the premix produced by some manufacturers is not up to standard, resulting in pigs.

Care of febrile pigs
The normal body temperature of pigs is 38 ℃ ~ 40 ℃. If it continues to exceed 40 ℃, it is feverish. Persistent high fever for a long time will accelerate the catabolism of the body, disorder of digestive function, decrease of resistance, and even cause coma or heart failure. The principles for the treatment of febrile pigs are as follows: feverish pigs are immediately isolated and the contaminated environment should be thoroughly disinfected. In the absence of a clear understanding of the cause, as long as it is not excessive fever, generally do not use antipyretic drugs at will. While using antimicrobials, we should pay attention to supplement nutrients.

Prevention of chicken acidosis in hot weather
Summer temperature is higher, leftover food overnight or feed damp, heat is very easy to rot and sour, after being eaten by chickens will stimulate the crop wall, causing inflammation. If the leftover food produces too much acid in the process of spoilage, the acid will enter the bloodstream through the crop wall and intestinal wall of the chicken, leading to chicken acidosis. After the occurrence of acidosis, the general crown of the chicken is purple, standing apart from the group, the wings are drooping, the feathers are fluffy, the intake is greatly reduced, and even refuse to eat. If you press the crop with your hand, some are empty, some are full of liquid, and if you mention a chicken, a foamy sour liquid will flow out of its mouth, and the illness is serious.
