Problems solved by technology

[0005] However, although simply combining beneficial bacteria and oligosaccharides can improve the survival rate and proliferation ability of beneficial bacteria to a certain extent, the effect of compatibility cannot be achieved because the bidirectional selectivity between probiotics and oligosaccharides is not considered. Maximum performance, so not broadly applicable and efficient
And so far, there is no special probiotic oligosaccharide synbiotic product suitable for weaned piglets to improve piglet health and improve production performance

Embodiment 1

[0024] Example 1 Lactobacillus plantarum ZLP001

[0025] A high-performance probiotic strain isolated from the intestinal tract of healthy piglets with acid resistance, bile salt resistance and good bacteriostasis. The survival rate of the bacteria was 90.49% in an acidic environment with pH 3.0; the survival rate in 0.3% bile salt was 87.02%; it was moderately sensitive to Escherichia coli, Salmonella and Staphylococcus aureus. It was identified as Lactobacillus plantarum (Lactobacillus plantarum) by the China Industrial Microbiology Culture Collection Management Center, and it was named ZLP001. The strain was preserved in the Microbiology Culture Collection Center on March 27, 2013 (Address: Chaoyang, Beijing No. 3, No. 1 Yard, Beichen West Road, District, Institute of Microbiology, Chinese Academy of Sciences, 100101), the classification name is Lactobacillus plantarum (Lactobacillus plantarum) ZLP001, and the preservation number is CGMCCNo.7370. Experiments show that the ...

Embodiment 2

[0026] Example 2 In vitro culture experiment

[0027] 1. Materials

[0028] Probiotics: Lactobacillus plantarum ZLP001; Oligosaccharides: mannan oligosaccharides, isomaltooligosaccharides, fructooligosaccharides, chitooligosaccharides, xylooligosaccharides, soybean oligosaccharides, raffinseed oligosaccharides, inulin.

[0029] 2. Methods and Results

[0030] 2.1 Experimental design

[0031] Add mannan oligosaccharides, isomaltooligosaccharides, fructooligosaccharides, chitooligosaccharides, xylooligosaccharides, soybean oligosaccharides, cottonseed oligosaccharides, and inulin as carbon sources to the Lactobacillus plantarum culture medium, and screen out The best oligosaccharide for growth of Lactobacillus plantarum.

[0032] 2.2 Test method

[0033] Activation: Inoculate the frozen Lactobacillus plantarum liquid into the MRS liquid medium with a 1% inoculum, and incubate at a constant temperature of 37°C for 18 hours for later use (the number of viable bacteria is equiv...

Embodiment 3

[0055] Embodiment 3 feeding test

[0056] 1. Materials

[0057] 1.1 The strain selected for probiotics and oligosaccharide tests is Lactobacillus plantarum ZLP001, which was screened and preserved by our laboratory and identified by the China Industrial Microbiology Culture Collection Management Center. It has strong acid resistance, bile salt resistance and antibacterial activity , the total number of effective viable bacteria in its freeze-dried bacterial powder preparation is 10 9 CFU / g. The oligosaccharide used in the test was fructooligosaccharide with a purity of 95%.

[0058] 1.2 Selection of animals The experimental animals were 30-day-old “Du×Long×Da” triple cross weaned piglets. The experiment was carried out in a pig farm in Fangshan District, Beijing.

[0059] 2. Methods and Results

[0060] 2.1 Experimental design and experimental diet

[0061] A total of 84 weaned piglets (30±2) days old with an average body weight of 7.19±0.45kg “Du × Chang × Da” were sele...

Abstract

The invention provides a synbiotics feed additive special for piglets. The additive comprises Lactobacillus plantarum ZLP001 with the preservation number being CGMCC NO.7370, and fructo-oligosaccharide. According to the additive, the Lactobacillus plantarum ZLP001 and the fructo-oligosaccharide are combined, the optimized weight ratio of the Lactobacillus plantarum ZLP001 and the fructo-oligosaccharide is selected, namely the best synergy compatibility effects of the two annexing agents can be played, the effects generated by the common use of the two annexing agents are higher than those generated by single use of the two annexing agents. The additive can be widely popularized and applied in the field of livestock culture industry and has good market effects and social effects.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, in particular to a feed additive for improving the production performance of livestock and poultry. Background technique [0002] After weaning, piglets are prone to weaning stress due to multiple influences such as sudden change of food, environmental changes, and immature digestive system and immune system, which often lead to decreased appetite, slowed weight gain or even weight loss, diarrhea, and Severe growth retardation etc. Therefore, after weaning piglets, various measures should be actively taken to reduce the occurrence of stress reactions, enhance the intestinal function and immune function of piglets, increase the feed intake and digestibility of piglets' diets, and reduce the occurrence of diseases such as diarrhea and growth retardation in piglets. to ensure its normal growth. [0003] Weaning stress in piglets has been prevented and addressed for a long time by addi...
