Lactating sow compound feed and preparation method thereof

Abstract

The present invention discloses a lactating sow compound feed and a preparation method thereof. The compound feed is composed of the following raw materials (parts by weight): 200-250 parts of fermented soybean meal, 180-200 parts of fermented cottonseed meal, 150-170 parts of puffed corn flour, 70-90 parts of animal blood meal, 50-60 parts of brans, 50-60 parts of sweet potato vine powder, 30-40 parts of jujube leaf powder, 20-40 parts of mutton, 15-20 parts of black sesame, 20-25 parts of peas, 25-35 parts of peanut kernels, 10-15 parts of red beans, 15-20 parts of undaria pinnitafida, 10-15 parts of hemerocallis citrina, 8-10 parts of leaf lettuce, 3-5 parts of eggs, 2-3 parts of tetrapanax papyriferus, 3-4 parts of stemmacantha uniflora, 2-3 parts of cowherb seeds, 1-2 parts of astragalus mongholicus, 5-8 parts of pawpaw powder, 3-5 parts of pedicellus cucurbitae powder, 0.4-0.8 parts of salt and 10-15 parts of counterpoisons. The compound feed can provide sufficient nutrients for lactating sows, improve the milk yield of lactating sows, enable good reproductive performance of lactating sows after weaning, promote the growth and survival of piglets, and increase the raising rate and the weaning weight of piglets.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a compound feed for lactating sows and a preparation method thereof. Background technique [0002] Lactating sows generally refer to sows that are pregnant and lactating after giving birth. Lactating sows are in the most important position in the entire pig production line, because the nursing sows are well managed and fed, the sows are prone to estrus after weaning, and can maintain good reproductive performance, and it is easy for piglets to be transferred to the nursery after weaning Feeding, so as to lay a solid foundation for improving the growth rate of piglets; when the management and feeding of lactating sows are not good, the sows are too fat or too thin will affect the next estrus, the sows' empty period will be prolonged, and the piglets will grow poorly, and they will be transferred to the nursery Afterwards, it is difficult to feed and manage, and the bre...
