Lactation-promoting sow feed and preparation method thereof

Abstract

The invention provides lactation-promoting sow feed and a preparation method thereof. The formula of the feed is prepared from 20 to 40 parts of corn kernels, 5 to 25 parts of dried small shrimp powder, 10 to 30 parts of soybean meal, 12 to 28 parts of whey powder, 15 to 27 parts of spirulina, 9 to 21 parts of duckweed, 12 to 24 parts of nigella damascene, 8 to 24 parts of melodinus fusiformis leaf, 6 to 18 parts of dregea sinensis vine, 12 to 24 parts of primula cernua franch rhizome, 9 to 21 parts of stem of October clematis, 6 to 22 parts of helwingia japonica stem pith and 0.5 to 2 parts of probiotic bacteria. The preparation method of the feed comprises the following steps: (1) fermenting the corn kernels, the soybean meal and the whey powder; (2) reflowing and steaming the spirulina,the duckweed, the nigella damascene, the melodinus fusiformis leaves, the dregea sinensis vines, the primula cernua franch rhizomes, the stems of October clematis and the helwingia japonica stem pithby utilizing acetic acid; (3) mixing all the materials and carrying out secondary fermentation. The feed provided by the invention has the effects of clearing away heat and promoting lactation, dispelling wind and dampness, diminishing swelling and diminishing inflammation, enhancing the body constitution and the like.

Description

technical field [0001] The invention relates to the technical field of feed formula preparation, in particular to a lactating sow feed and a preparation method thereof.
