Farms should guard against excessive sow hyperactivity
The lyrical condition of binary sow sows has a greater influence on their reproductive performance. At present, the mass rearing of the binary cross sow is still following the traditional method of rearing local sows, which can easily lead to over-hyesthesia in the binary sow. Therefore, to prevent excessive hyperpigmentation in sows with binary crossbreeding, the key is to prevent gilts and pregnant sows from overeating, and the sows after nursing and weaning are too lean. First, the reason 1. The binary sow has the characteristics of good fattening performance, faster growth rate than the local sow, and strong fat deposition ability. Overfeeding on a daily basis or unbalanced feed nutritional ratios, abuse of fattening pig additives, gluttony, snooze, and severe lack of exercise result in increasing fatness, often occurring in gilts and pregnant sows. 2. Excessive suckling Sanyuan piglets, long lactation period, combined with the three yuan piglets larger than the dual piglets individual, the amount of sucking milk is also large, resulting in a large number of nursing sows use the body reserves, in isolation weaning, the body condition is thin Only one skeleton remains. With severe internal and external parasites, labor or illness, poor body condition often occurs in late lactating sows. Second, the harm Excessive hyperactivity of the sow can easily lead to endocrine disorders, non-estrus symptoms or symptoms are not obvious, ovulation is small, egg viability is weak, reproductive failure occurs, the number of infertile, empty, and fewer litter size. Excessive deposition of fat around the body and reproductive organs hinders ovulation, fertilization and fertilized egg movement, implantation and fetal development. There is a long production process at the time of childbirth, a weak contraction force, difficulties in output, and a large number of weak babies or stillbirths. The body is too bulky and obese. In the early stages of childbirth, it is easy to crush and suffocate newborn piglets. Third, prevention 1. Feeding properly, providing a balanced diet for nutrition is the key. Should take a sub-feeding: 1 after weaning, early pregnancy (21 days after mating), to make the recovery of sensation as soon as possible, poor sensibility should adopt "short-term excellent feed", supplement protein feed, ensure timely estrus and embryonic normal ovulation , reduce early embryonic death. 2 Late pregnancy (after 80 days), attention should be paid to the intake of sufficient protein, especially animal protein, to the pregnant sow to meet the needs of the fetus for large amounts of deposited nutrients and weight gain. 3 Pre-harvest period (one week before delivery) is suitable for reducing the amount of feed, when the sow is too lazy to move, feeding too much will affect post-natal feed intake, resulting in decreased milk production and poor milk quality. 2. Early weaning (28 to 35 days of age) was carried out by fortifying the piglet and inducing early feeding and feeding. 3. Do regular pest control and epidemic prevention. After weaning in each breeding cycle, to the pre-mastaging stage, we injected “three-joint seedlings†to consolidate the epidemic prevention. We changed the routine use of “levamisole†to drive only the internal parasites and chose avermectin†(developed by North Agricultural University). Can exterminate the body and the external parasite.Strengthen the postpartum and disease sow care to ensure that the public opinion is not affected. 4. Proper exercise. Free exercise within one month of pregnancy, exercise should not be too much. 40 to 80 days of pregnancy can be fully exercise, 1 to 2 hours a day, 80 to 105 days of free activities. A week before delivery is not suitable for activities. 5. Feeding sows without finishing pig additives, supplying minerals with trace elements and vitamin supplements, and supplementing green feed as much as possible.
