The farm production level has a direct impact on the profitability of the farm. If the profit of the farm is high, the key is to have a lot more children, fewer deaths, and faster growth. At present, the average litter size of sows in domestic pig farms can reach 11 or so, and the average number of pigs listed on the market per sow is very small. The key factor is that the survival rate of piglets is not high, and there are many pigs with sick and dead diseases. Fat pigs have a slow growth rate, a high feed-to-meat ratio, and a high cost. They are in a loss-making state all year round. Production practice shows that: To improve the survival rate of piglets and to reduce the ratio of pork to pork, the nursing of newborn piglets is particularly critical.
To prevent the poor vitality of newborn piglets
Weakness will inevitably lead to problems such as high morbidity, high mortality, and low growth rate. Weak individuals who have a primary weight of less than 0.8 kilograms or who are unstable in standing and do not eat milk will be able to prevent poor vitality of newborn piglets.
Supplementing the sows with sufficient reproductive nutrients during pregnancy will allow the uterus to develop well in the blood vessels of the uterus, secrete more uterine milk, promote the development of the piglets, and achieve ideal birth weight and vitality, especially during the late period of pregnancy.
Doing sow production to prevent the production process is too long. When the umbilical cord connecting the piglet to the sow is broken and there is no output for a long time, there will be oxygen deficiency and sudden death or poor vitality will become weak.
Preventing newborn piglets from eating into feces
When a piglet is born, he is born to know that he has a baby and he is thinking about feeding. During clinical production, the sows do not undergo strict cleaning and disinfection of the breast and hindquarters. The piglets are fed with feces as soon as they are born. They infect the pathogenic microorganisms and cause diarrhea. The incidence of disease has increased significantly.
Prevent piglets from catching cold
Timely dry the amniotic fluid on the piglet to prevent the amniotic fluid from entering the piglet's lungs and prone to pneumonia. The amniotic fluid is eaten into the stomach and affects the digestive ability. The amniotic fluid on the body is not wiped off in time and it is cold and diarrhea, and the incidence or vitality is reduced. After giving birth, especially for the first 6 hours, great care must be taken to give the piglets good insulation.
Prevent piglet cord blood loss
After the piglets are born, they should stay for 2 minutes to 10 minutes and then cut off the umbilicus, which can effectively alleviate the piglets' anoxic state. The piglets' vitality and constitution are well improved, and their growth and development will be better in the later period; the umbilical cord should be paid attention to when the umbilicus is broken. The length is generally 3 cm to 5 cm, so the umbilical cord does not touch the ground when the piglet stands. Umbilical cord blood contains a large number of hematopoietic stem cells, which are critical to the piglet's constitution, immunity, and growth rate. During the production process, attention must be paid to the treatment of the umbilical cord to prevent cord blood loss.
Prevention of sow milk shortage
During production, piglets must be fed colostrum to absorb maternal antibodies in breast milk as soon as possible, and they need to fix the teats to help the piglets to eat colostrum; within three days of the piglet’s birth, the delivery room staff must carefully observe the status of the piglet’s feeding. The quality of sow milk, promptly carry out the foster care of piglets, develop a corresponding postpartum health care program for sows, and prevent the lack of sow milk and poor milk quality.
Prevent being trampled and killed
In clinical production, the squeezing death of newborn pigs accounts for about 50% of the deaths. Therefore, it is very important to prevent the crushed piglets from being killed. We can solve the problem in five aspects:
1. Select good mother sows to retain seed, and do a small perinatal sow health care to promote postpartum recovery of sows.
2. Carry out the training of the piglet so that the piglet can sleep in the incubator after eating milk, which can effectively prevent the piglet from catching cold. Especially when the sow is fed within three days of age, the piglet must be thrown into the incubator, After the pig had finished lying down, she released the piglets.
3. To strengthen the control of the temperature in the delivery room. When the temperature in the delivery room is higher than 23 degrees Celsius, the proportion of dying piglets will increase by 50%.
4. The use of a bed with a better design can reduce the death of piglets in the delivery room.
5. Strengthen the training of the delivery room staff and adjust their assessment plans to increase employees' awareness of preventing piglets from crushed to death, so that the delivery room is 24 hours apart.
Prevent wound infection
In order to prevent grabbing of milk and fighting, when biting each other and biting the sow's udder when mastitis occurs and reducing the milking force, the piglet must be cut and tailed, and the time should be 24 hours after the piglet is born. Inside, and need to be disinfected and check if the teeth are cut flat. Long-acting cephalosporins are also used for effective health care at the time of cutting off the teeth, preventing pathogens and stress in the wound infection environment from declining resistance, and improving uniformity of piglets and weaning weight.
Prevent iron deficiency anemia in piglets
After the piglet is born, it contains about 50 mg of iron. Only 1 mg of iron can be eaten from the sow's milk every day. The growth and development of piglets requires 7 mg to 10 mg of iron per day. Usually after 5 days of age, the piglets will In the presence of iron deficiency anemia and slow growth, piglets must be supplemented with iron once at 2 and 10 days of age. Iron supplementation should be carried out according to the piglet's size. When the piglet’s initial weight is less than 1 kg, once Iron 2 mg or more is prone to poisoning and allergies.
