1. Dirty sows enter the farrowing room and there is almost no disease resistance. The pathogens are most likely to invade and cause piglets to get sick. Because the sows have completely cleaned and disinfected the incubator before the bed, they are brought in by the sows. Disease is the main source of infection. It is even more important to cleanse and disinfect prenatal sows. 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, pre-natal breast milk is not the only source of nutrition for suckling piglets, and the pig's breasts 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 during sow pregnancy, carry out inspections and take appropriate measures against unsatisfactory breasts, we will increase 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 the phenomenon of excessive temperature in the delivery room, but not conducive to piglet growth and development, because the high temperature in the delivery room will reduce the sow feed intake, lactation The quantity is small and there is insufficient supply of nutrition for piglets. When the outside temperature is high, the piglets often go outside and do not know how to return to the incubator. The crushed death rate increases, and if the temperature is not stable, the piglets will fall outside and the temperature of the homes will decrease, causing the piglets to suffer from colds or diarrhea. 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, the sow material undernutrition According to some scholars research, sows to meet the maximum growth of piglets, feed intake need to feed more than 8 kilograms per day, and we now sows feed intake of less than 8 kilograms, to increase Sow nutrition, 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. Fifth, lack of necessary sow care and health care Sow postpartum, the body is extremely weak, disease resistance, reduced digestion, both susceptible to pathogen infection and disease, but also prone to constipation, loss of appetite and other adverse reactions, sows Postpartum care and health care are quite 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 the 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 the water is better than that in the material.) (3) Feed with good taste and light laxative effect.
