Core Tip: The five loopholes in the management of the sow delivery room are: dirty sows entering the delivery room, not checking the sow's breasts before delivery, high temperature in the delivery room, insufficient nutrition of the sow feed, lack of necessary sow care and health care.
First, dirty sows into the delivery room
After the birth of the piglet, there is almost no resistance to disease. The bacteria are most likely to invade and cause piglets to become ill. Because the sows have completely cleaned and disinfected the incubator of the obstetrics before the bed, the disease caused by the sow is the main infection channel. It is even more important to clean and sterilize sows before going to bed. Some pig farms use two flushing methods at a time, combined with measures such as cleaning up the sow at any time, effectively reducing the risk of early pregnancies in piglets, that is, cleaning the sows’ body filth in the breeding houses and then using the chemicals. Once sterilized, the pigs should be sterilized once they reach the upper part of the bed and the pathogens should be minimized. At present, some pig farms are still unable to do the cleaning and disinfection work before the sow goes into the house, hoping to attract enough attention.
Second, do not check the sow breast before giving birth
Breast milk is the only source of nutrition for suckling piglets, and the breasts of pigs are different from other animals. A piglet only eats milk from one nipple and has the habit of fixing the nipple. Once it is fixed for life, it will remain unchanged. Whether the breast is normal or not will determine whether a piglet survives or develops normally. Swelling or atrophy of the sows' udder is common in production, resulting in insufficient secretion of breast milk, impaired development of piglets due to malnutrition, predisposition to disease, and increased mortality. If we can focus on the breast when the sow goes to bed, conduct inspections and take appropriate measures on the unsatisfactory breasts, we will increase the lactation during lactation and improve the survival rate of piglets. At the same time, checking the number of effective nipples in advance will also provide a basis for fostering after birth, which is more conducive to the survival of newborn piglets.
Third, the delivery room temperature is too high
People have recognized the importance of temperature on the survival of piglets, but often there is a phenomenon that the temperature in the delivery room is too high. It is not conducive to the growth and development of piglets, because the high temperature in the maternity ward reduces the intake of sows, and the amount of lactation is low. The nutritional supply of piglets insufficient. When the outside temperature is high, the piglets often go to the outside and do not often return to the incubator. The crushed death rate increases, and if the temperature is not stable, the piglets can fall outside and sleep at a lower temperature, which can lead to colds or diarrhea in the piglets. Too high temperature in the delivery room wastes energy and is not conducive to piglet production. Under normal circumstances, the delivery room temperature is reasonable between 18°C ​​and 22°C. Above 24°C, there will be a decrease in the sow feed intake. Therefore, if the piglets have incubators and heating equipment, the indoor temperature should not be raised too much.
Fourth, sows feed poor nutrition
According to some scholars' research, sows are required to satisfy the maximum growth of piglets, and they need to feed more than 8 kilograms of feed per day. However, we currently have sows with a feed intake of less than 8 kilograms, in order to increase sow nutrition and increase nutrient concentration. Is the only way. The method for increasing the energy concentration is to add animal and vegetable fats and oils, and increasing the amount of several limiting amino acids can be solved by adding a single amino acid. Many pig farms have not been able to use the balance of energy protein or the balance between energy and amino acid ratios and amino acids when selecting feedstuffs. Instead, they blindly increase the content of crude protein and the results have not improved. The effect of breast milk, but due to high protein content increases the metabolic burden in the body.
V. Lack of necessary sow care and health care
After sows are born, the body is extremely weak, disease resistance is reduced, digestive ability is weakened, it is easy to be infected by pathogens, and it is also prone to adverse reactions such as constipation, loss of appetite, and sow postpartum care and health care is very important. In postpartum health care, there have been injections of penicillin, long-acting oxytetracycline, and cephalosporin, and there are also recommended methods of adding drugs to prevent the use of drugs such as Zhiyuanjing, fluorocresol phenolomycin, etc. Nice effect. However, these methods are still not used on some farms, either because the price is high, or because of the high number of injections, or because they do not see obvious results. This is not conducive to the health of the sows and is not conducive to the development of the piglets.
In sow care, the following methods are worth referring:
(1) The uterus is washed after artificial birth.
(2) sows give drink rehydration brine after delivery to enhance physical strength and promote bowel movement. (The effect of adding anti-inflammatory drugs in water is better than that in the material)
(3) Feed with good taste and light laxative effect.

A mixing system sterile medicine mixer (powder and liquid ) is a device that mixes powder and injection before injecting the drug into the patient.But traditional booster injection infusion dispensing still exist, need medicine soluble medicine, when dispensing, repeated shocks and mixed extraction liquid, in the process of repeated puncture easy to produce plastic particles, particles stopper is getting into the human body easily blocked blood vessels, granulation, some problems of inflammation, and the ward of bacteria, viruses, repeatedly extracting liquid easy to carry the virus in the air, infusion to the solution of the problem.
Transfer the fluid under the conidition of sterilization. Much easier, quicker and cleaner.
