Keeping sows should pay attention to the following aspects:
First, sow breeding and management:
Sows are more extensively reared, especially in rural areas. Green roughage is the main ingredient, and the feed mix is ​​diversified. It plays a role in complementing the nutrients. In the late period of pregnancy and lactation, the feeding method of the fine material is appropriately added. The lean and thin sow should be supplemented after the breeding, so that It resumes its physical condition as soon as possible and assumes the heavy task of conceiving a child. This feeding method has low cost, high income, and high economic efficiency.
Sows are generally single-circled. There are two critical periods for pregnant sows. One is the period of 17 to 22 days after mating. It is the fertilized egg that is implanted in the uterine horn. The fertilized egg is in a free state and is not firm. If this period is not well managed, put a few in a circle. , Pigs fight each other between Europe, crowded with each other, housing uneven, so that the sow fell or chasing sows, are likely to cause miscarriage. In addition, salt, bone powder or eggshell powder and vitamins and minerals should also be added to the feed. After this period, green coarse fodder can be used more, and less concentrated material is used to prevent the sows from becoming over-fat. Second, the period from 90 days to output of the pregnant woman is an extremely fetal development stage, especially during the last 20 days. Re-occupy about 60% of its initial weight, sows have a strong appetite, if poor feeding and management, lack of nutrition, fetal hypoplasia, sows will lose weight due to the consumption of their own nutrients. Conversely, if the sow is fed too much fat, it can hinder the growth and development of the fetus, resulting in miscarriage or stillbirth.
Second, the estrus and breeding of sows:
The sow is a multi-cycle estrus animal that breeds throughout the year. The estrus cycle is 21 days. The appropriate initial age of sows: the introduction of the species is 8 to 10 months of age, weighing about 100kg; local varieties of 6 to 8 months of age, weight 70kg ~ 90kg or so. Premature mating will affect the growth and development of sows and birth weight and lactation.
The timing of sow breeding should be well-known. As the saying goes, “Older and earlier, less late, and not much older.†The timing of mating is also related to breeds. Local breeds have obvious estrus symptoms, mainly manifested as: Outflow of mucus, frequent urination, unsteady behavior, cramps, food intake, standing still when pressing the sow's back, ears erected and so on. The maturity of lean-type pigs is relatively late, and the estrus symptoms are not obvious. In order to improve the conception rate, the keeper must carefully observe and master the changes of the pus and the behavior of each sow. The hybrid sows are usually distributed on the afternoon of the second day or on the third day after the onset of estrus. In other words, it is most appropriate to have the boar's waist position immobilized. In order to make the sow more fetuses, repeat mating and double mating are used. Repeated mating is performed 20 to 30 hours after the start of oestrus, then 12 to 18 hours apart, and then the same boars are used for breeding for the second time; while double mating uses two boars of different species at intervals of 5 to 15 minutes. Have one each time. This will increase the rate of conception and achieve the goal of high yields.
Third, the sow's conception and birth:
After sowing, the sows are no longer in heat for more than 20 days, and their food intake is increased. The hair is shiny, and the temperament becomes docile, tired, snoozing, the vulva shrinks, and the tail hangs down. Generally, the sow is considered to be pregnant. About 90 days of pregnancy, gently press the abdomen with your hand, can touch the fetus. The sow's gestation period is generally 112 to 116 days (local pigs have short gestation periods and longer pigs to be introduced; younger pigs have shorter gestation periods and longer production pigs), with an average of 114 days, ie "three or three." Three (three, three, three days). In order to prepare for prenatal work, the expected date of each sow should be calculated.
7 to 10 days before birth, to completely clean, disinfect the production circle, pad with soft, shredded mat grass, ready to take delivery tools, arrange day and night duty personnel. 3 to 5 days before delivery, the sows have symptoms of labor: breast enlargement, fever, milk hair, red, bright, thick, and sometimes can be squeezed out a small amount of thin milk. The vulva is swollen, loose, red, or purple in color, and thin mucus flows out of it. A day or night before delivery, most sows in the front of the nipple can extrude or leak yellow colostrum with more viscous colostrum. The sow is disturbed by actions, such as the sow is lying uneasy, when she is lying, the movement, the tail roots are lifted, sometimes urination, start pain, and the mucus outflow from the vulva, it means that the child will be delivered immediately. Producers should carefully disinfect and prepare for confinement, allowing sows to enter the delivery room and move into the delivery bed. Wash and disinfect the sows before going to bed, especially sows' nipples should be washed. In order to prevent the sow's nipple from being dirty, digestive tract diseases occur in piglets. During the sow giving birth, it is strictly forbidden for a living person or a child to watch lively or loud noises at the scene so as not to panic and tamper with the sow and affect the delivery or squeezing of the piglets. After all the piglets have been delivered, the confinement workers should immediately remove the mucous membranes from the mouth and nose of the piglets, wipe the whole body, and immediately cut the umbilicus. Excreted tires should be removed immediately and sows are strictly prohibited from swallowing. Feed the postpartum sow with warm bean cake, bran or rice bran, and add some salt as appropriate. 2 to 3 days after childbirth, do not feed too much too thick, feed modulation into a thin porridge-like, feeding gradually increased.
In short, sows have economic value for 5 to 6 years in their lifetime, and good sows have 8 years of economic value. Older sows should be eliminated, otherwise there will be fewer litters, weaker breeders, and stillbirths, and the significance of raising sows will be lost. The level of conception of sows is also directly related to the early and late mating of the primiparous sows, overweight body condition, overweight, and diseases of the reproductive system. For example, the primiparous sows have lower fertility than the gilts, and the estrus breeding period does not allow the affected fetus to be affected. The gilts are over-fertilized and the fetus is too overweight to be affected by the fetus. For infertile sows, reproductive system diseases (such as endometritis, vaginitis, etc.) must be taken into consideration and should be promptly treated.
How to raise sows
Raising sows is a prerequisite for productive piglets and healthy piglets. As the saying goes, "mother and child fat" is completely correct. Sows require good health, long shape, large body, wide chest, wide hip, high hips, long legs, straight or slightly bent waist, high weight gain, high feed reward, neatly arranged nipples, prominent nipples, and effective nipples In 7 pairs or more, the genitals developed well without reproductive defects.
