Problems solved by technology

At present, there are also some microbial compositions for piglets, but the existing microbial compositions are mainly aimed at post-weaning piglets, and the effect for lactating piglets is poor, and cannot effectively increase weight or reduce diarrhea rate and mortality

Embodiment 1

[0069] Prepare the microbial composition with reference to the following methods:

[0070](1) Preparation of Lactobacillus plantarum subsp.plantarum (Lactobacillus plantarum subsp.plantarum) Zhang-LL (CGMCC No.6936) freeze-dried bacterial powder: ① Strain activation: L.plantarum Zhang-LL strain in glycerol storage tube according to 2 % inoculum amount inoculated into 10mL sterilized improved MRS culture medium, and cultured at 37°C for 12 hours; ②Strain fermentation: Inoculate the bacterial liquid obtained from the above culture into 100mL sterilized improved MRS culture medium according to 2% inoculum amount, and other culture conditions were the same as above ; ③Strain fermentation: inoculate 1 000mL sterilized and improved MRS culture solution with the above-mentioned expanded culture solution according to 2% inoculation amount, and the fermentation time is 16h, and other culture conditions are the same as above; ④Thalline collection and freeze-drying: after the fermentation...

Embodiment 2

[0074] Prepare the microbial composition with reference to the method described in Implementation 1, the only difference is that the viable counts of L.plantarum Zhang-LL and B.coagulans Liu-g1 in the microbial composition are 1.0×10 9 CFU / mL.

Embodiment 3

[0076] Prepare the microbial composition with reference to the method described in Implementation 1, the only difference is that the viable counts of L.plantarum Zhang-LL and B.coagulans Liu-g1 in the microbial composition are 1.0×10 10 CFU / mL.

Abstract

The invention provides a composite microorganism composition and feed for piggies at a lactation period. The composite microorganism composition comprises the following two strains namely lactobacillus plantarum Zhang-LL of which the preservation number is CGMCC No.6936 and bacillus coagulans Liu-g1 of which the preservation number is CGMCC No.10790 in the viable count ratio of the lactobacillus plantarum Zhang-LL to the bacillus coagulans Liu-g1 being 1 to (0.5-2). According to the composite microorganism composition, the average daily gain of the piggies at the lactation period can be effectively increased, the diarrhoea rate and the mortality rate of the piggies at the lactation period are reduced, and the digestion function and the immunity of the piggies at the lactation period can bestrengthened.

Description

technical field [0001] The invention relates to the field of microbial compositions, in particular to a compound microbial composition and feed for suckling piglets. Background technique [0002] Piglets refer to pigs from birth to about 70 days old. Piglets can also be divided into two stages, namely the lactation stage and the nursery stage after weaning. Piglets in the lactation stage refer to piglets from birth to weaning, generally from birth to growth to about 1 month, and the main feeding method is sow-feeding or breast-feeding + feed. The piglets in the nursery stage refer to the stage of piglets after weaning, and their main feeding method is whole feed feeding. [0003] Piglets in the lactation stage and piglets in the nursery stage are both in the piglet stage, but their physiological and developmental states are quite different. Compared with the piglets in the nursery stage, the digestive system of lactating piglets is not fully developed, the activity of sali...
