Scientific lactation method for lactating sows

The milk quality of lactating sows, that is, the amount of milk secreted, directly affects the growth rate and health of piglets. Therefore, once lactation or lactation of lactating sows must be carried out scientifically, the types of lactation analysis of sows are as follows:

The main results are as follows: 1. lactation method of parturient sows: the lack of milk in parturient sows is mostly caused by inadequate breast development or low dietary nutrition level. Therefore, the breast should be artificially massaged 1-2 times a week before and after delivery to promote the recovery of breast development and lactation function. For postpartum sows with less milk, you can use 1-2 placentas of healthy sows, chopped, fried soup in 3 times, or people with lactation tablets 1-100 tablets.

Second, parturient sows: most of them are caused by mastitis or systemic diseases, which should be fundamentally treated, adjust gastrointestinal function, supplement some green feed, and treat with traditional Chinese medicine: Huangqi Wang Bu Xing 200g decoction, one dose a day for 3-5 days, the lactation effect is good.

Third, the method of lactation of obese sows: due to excessive fat of sows, resulting in lack of milk or lack of milk, the treatment of hormone lactation. Subcutaneous injection of prolactin, 50-1000 international units each time, twice in a row, or 30-50 units of oxytocin, the injection effect is very good. In addition, it reduces the energy and protein in the feed.

Fourth, lactation of too thin sows: postpartum milk deficiency of thin sows is mainly due to malnutrition and some consumptive diseases, resulting in milk deficiency, symptomatic treatment and adjustment of the diet, adding 20% corn, 10% bean cake and 20% bone meal in the diet, while boiling soup with pig bones and adding feed towels to feed.

5. Multiple and prolific sows: for multiple births, uneven litter size or less litter size, sows with lactation at least 8 parities should be eliminated. For fertile sows, the following two methods can be adopted: a, foster care: sows with fewer offspring are raised by sows with fewer litters, and the principle is "large and strong". The reason is to raise the big and strong ones in the original litter to sow towels with less litters and foster care at night to reduce stress. The number of days in foster care should be that the delivery period of sows and foster sows should not exceed three days of age, and food can be induced earlier. Sows should add high-energy protein, can add some vegetable oil, add 3% animal oil, increase milk yield to meet the nutritional needs of piglets.

Measures to promote ovulation in sows

1. Seduction: with the method of trial, boars chase sows that have not been in estrus for a long time, or boars and sows are kept in the same circle to promote oestrus and ovulation.

2. Early weaning: in general, for pig farms with medium technical conditions, early weaning can be used, preferably no more than 5-6 weeks.

3. Nestling and controlling lactation time: the piglets born to Shaowan sows will be fed to other sows 3 days after eating colostrum. In this way, the pig is no longer breast-feeding, it can quickly estrus and breed. Control lactation time ask, that is, after training piglets to eat early, adopt the method of isolating mother and litter, control lactation time and lactation times, sows begin oestrus 6 Mel 7 days after non-lactation time.

4, hormone aphrodisiac: the hormones commonly used in production are pregnant horse serum, chorionic gonadotropin or estrogen. Pregnant horse serum can be in estrus for 4 days after subcutaneous injection of 5 ml each time, and chorionic gonadotropin is suitable for intramuscular injection of 1000 units in medium sows.

5. Traditional Chinese medicine: 40g Angelica sinensis, 40g Chinese angelica, 30g Chinese yam, 30g Chinese yam, 30g Chinese traditional medicine, 30g Chinese angelica, 30g Radix Astragali, 30g Chinese yam and 30g cooked land.
