A composition containing probiotics and compound extract for improving the farrowing rate of sows and the birth weight of piglets

Abstract

The invention belongs to the technical field of agricultural breeding, and particularly relates to a composition capable of increasing the farrowing rate of sows and increasing body weight of new-bornpiggies, and containing probiotics and composite extracts. The composition comprises bacillus subtilis, lactobacillus acidophilus, an enterococcus faecalis mycoplasm extract, radix astragali, radix codonopsis, radix angelicae sinensis, honeysuckle flowers and a herba epimedii extract. Compared with the prior art, the composition disclosed by the invention has the following advantages that extraction is performed on enterococcus faecalis to obtain the enterococcus faecalis extract, and the enterococcus faecalis extract is mixed with probiotics and a traditional Chinese medicine extract, so that the composition can be obtained; improvement of digestion and absorption of nutrient substances by pregnant sows at middle and later stages can be further facilitated; a micro-ecological environmentwhich is beneficial to beneficial bacteria and capable of resisting diseases is created in intestinal tracts of the sows, so that the capacity of the sows, for resisting the diseases is strengthened,the production amount of endotoxicity is reduced, and the infectious rate of the sows to descendants is reduced; and after the composition is added, the fat content in milk of the sows during 24 hours after delivery can be increased, the farrowing number of the sows can be increased, the new-born weight can be increased, the propagation life is prolonged, and the generation of postpartum metritisand postpartum vaginitis of the sows is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a composition containing probiotics and composite extracts for improving the farrowing rate of sows and the birth weight of piglets. Background technique [0002] Reproductive performance of sows is a key point in the production and management of pig farms. There are many influencing factors, which can be summarized into two aspects: in vivo and in vitro. The nutrition of sows during pregnancy, especially the nutrition in the late pregnancy, has a greater impact on the change of fetal weight. If Nutrient intake cannot meet the growth and development requirements of the fetus, and the sow will have a negative nutritional balance, and the birth weight and weaning weight of the piglets are relatively small. Nutritional needs for growth, sow delivery and lactation, but after the sow enters pregnancy, the anabolism is strengthened, and the utilization rate of...

[0002] Reproductive performance of sows is a key point in the production and management of pig farms. There are many influencing factors, which can be summarized into two aspects: in vivo and in vitro. The nutrition of sows during pregnancy, especially the nutrition in the late pregnancy, has a greater impact on the change of fetal weight. If Nutrient intake cannot meet the growth and development requirements of the fetus, and the sow will have a negative nutritional balance, and the birth weight and weaning weight of the piglets are relatively small. Nutritional needs for growth, sow delivery and lactation, but after the sow enters pregnancy, the anabolism is strengthened, and the utilization rate of nutrients is improved. It is not suitable to feed high-energy feed. Restricted feeding is implemented to reduce the energy in the feed content, can reduce the mortality of embryos, but correspondingly, the litter rate and piglet birth weight are also correspondingly reduced, so further research should be carried out on the feed for sows in the late pregnancy
