Note that the supply of sow full-strength compound feed does not arbitrarily change the feed formulation or refueling during lactation, disables the high-energy feed, and prevents the feeding of mildewed feed. Feeding lactating sows without the usual high-energy ratio hog feed. In combination with sow feed, limit the ratio of corn and other energy feeds below 60%; crude protein content should not be less than 18%. The sows began to reduce their diets 7 days before they were born. A small amount of salt-added bran water was given on the day of litter, and the feed was gradually added after the birth so that the sows could evenly secrete the milk with good quality and sufficient quantities to facilitate the digestion and absorption of the piglets.
Try to ensure that the sow is healthy and disease-free during the lactation period. Provide the sow with a suitable environmental condition. Pay attention to sunstroke prevention and cooling in the summer, keep the cold warm in the winter, and strengthen the sow's constitution; remove the excrement in time and keep the house clean, dry, and hygienic. The sows’ prenatal production circle is cleaned and covered with dry alfalfa; on the day of production, the sows’ udders and chest and abdomen are washed first, and 0.01% potassium permanganate solution is used to disinfect, and a few drops of milk from each nipple are squeezed out. Let the piglets feed on them.
