The status of sows in pig farms is unusual, which is an important guarantee for higher-than-forecasting, is the focus of epidemic prevention, and is also the most demanding technology for pig farms. The sow breeding problems in small and medium-sized pig farms are generally prominent. The basic sow refers to the weaned first sow, which is the main body of the sow in the pig farm. Here, the basic sow's feeding technology will be summarized.
First, before weaning until estrus, do not deliberately reduce the material after weaning, but the material should be replaced with empty sows. The material at this stage is characterized by high sugar, high protein and micronutrients. The small and medium-sized fields that are not available in the conditions can be fed on the basis of the pregnant sow material, with the addition of 200 grams of glucose plus 5 grams of energy per day.
Secondly, select adult boars with more libido and more saliva for the sow house to be induced each day. The sows should be in direct contact with the boars twice a day for 15 minutes. At the same time, strengthen exercise and light. Sows who did not have metritis during breast-feeding were given a prostaglandin preparation first. The next day, they were given 1000 units of maternal serum, and 500 units of chorionic gonadotropin were injected after estrus.
Third, mating sows should be between 18 mm and 22 mm in thickness when they are mated, or the body size can reach 3 points. It is more appropriate to match two times when mating: When the static reflection occurs, it is assigned once, and the next 8 hours to 16 hours are assigned the second time.
Fourth, to avoid various stress factors during the first months of breeding during pregnancy, feed should be changed to pregnant sows, 4 kg per day for the first month, 5 kg per day for the second and third months, and 1 month before childbirth. Instead of sow feeding, 6 pounds per day. At this time, pay attention to increase the proportion of coarse material as much as possible so as to increase the dietary volume of the sow's gastrointestinal tract. The use of Oleoc for sows is usually added to sow feeds, which helps increase the sow's milk production, increase the birth weight of piglets, and reduce yellow and white piglets.
Fifth, five days after giving birth, the sow needs to be treated for five days after birth: Yabo 25g + Lihuening 10g + Zhongwei Lengxing 5g / sow, each with 5 days to 7 days before and after childbirth. Yabo is Liuweidihuang Powder, which is a good medicine for nourishing the liver and kidney and regulating the function of the reproductive system. Lihuanning is an antibacterial anti-inflammatory drug that is very sensitive to the digestive tract and respiratory tract bacteria. Zhongwei Xingnengxing is an effective drug that can effectively supplement sow's physical micronutrients. The combination of the three can effectively reduce the various diseases of sows after delivery. In addition, the end of the sow's birth should also be a Longmi first (20 ml) or long-acting cephalosporins, while playing a prostaglandin preparations.
Sixth, the sows are born on the same day without feeding or only one pound of bran wet mix. Gradually increase the amount from the second to the fifth day to the maximum: 3 pounds + number of piglets multiplied by 1 pound. At this time, we will focus on the summer cooling of sows and winter warming of piglets. To reduce the daily intake of sows, use less feeding. In addition, additional 1 and 1.2% lysine was added to the sow feed. Our ultimate goal is to achieve a daily feed intake of 10 pounds or more for lactating sows and 20 pounds or less for weaning sows.
Seventh, to purify pathogens, sows should be immunized once every three or four months for swine fever, pseudorabies, foot-and-mouth disease, ring, and blue ear disease vaccines. The JE should be vaccinated one month prior to the mosquito epidemic. The vaccine should also be vaccinated in conjunction with the prevalence of the epidemic. The sow uses silver Qiao San 2 kg to 3 kg per ton of material each month for 7 consecutive days, which can effectively relieve sub-health and increase the immune effect.
Eighth, to ensure the quality of feed, it is necessary to prevent the harm of mycotoxins. Every time ingredients are dispensed, fans are used to remove the bad particles and dust. When the mycotoxin is still heavy, it uses a one-ton ton of Neumann Neumann's 1kg ingredient for long-term use.
In the ninth, each month, 6 to 8 fetal sows were supplemented with Zhongweijuenxing (1kg/ton) for seven days. For high-grade (greater than 9) sows and poorly productive sows, they should be eliminated in time, and the elimination rate is 25% to 30% per year.
