Detailed Explanation of Key Technical Points for Categorized Galactagogic Techniques in Sows

First-Litter Sows

Hypogalactia in first-litter sows is mostly caused by insufficient development of the mammary system or a low nutritional level in the daily ration, so their nutritional needs for both growth and lactation should be met as fully as possible. When hypogalactia occurs in first-litter sows, 1-2 fresh afterbirths can be taken, chopped, cooked, and added to the sow's feed, then fed in 2-3 divided portions.

Multiparous Sows

Hypogalactia in multiparous sows is mostly secondary. Galactagogic treatment should follow the principles of eradicating the underlying cause, adjusting the daily ration, and feeding more green, succulent feed. Use 200 grams of daylily, decoct in water, mix with feed, and feed; 1 dose per day for 3-5 consecutive days.

Obese Sows

In obese sows, the parenchymal organs of the mammary system are infiltrated by fat, which affects the endocrine system and reduces milk secretion. Hormonal galactagogic treatment is the first choice. By subcutaneous injection of prolactin, 500-1000 international units per sow each time, once daily for 3 consecutive times, the effect can be evident.

Thin and Weak Sows

The main cause of their hypogalactia is malnutrition. First check whether the nutritional composition of the sow's feed meets the requirements of feeding standards, then check whether the sow has parasitic diseases or other wasting diseases. After removing the cause, follow the principle of nourishing to restore the sow's physique and promote milk secretion.
