Problems solved by technology

[0009] At present, the main micro-ecological preparations in the domestic and foreign markets are mainly Lactobacillus and Bacillus subtilis. Although Lactobacillus has a strong acid-producing ability, it is not heat-resistant and dies due to heating during the feed pelleting process. Therefore, most microbial feed additives use resistant Bacillus subtilis with high heat and high production of digestive enzymes, but Bacillus subtilis does not produce lactic acid

Embodiment 1

[0031] Example 1 Preparation of Microecological Synbiotic Feed Additive

[0032] 1. Weigh the oligosaccharides as fructooligosaccharides, xylo-oligosaccharides, isomalto-oligosaccharides and soybean oligosaccharides each 10Kg for use;

[0033] 2. Preparation of Bacillus lactis preparation:

[0034] The strain is freeze-dried lactic acid bacillus; the weight of the lactic acid bacillus medium is composed of the following components: 0.5 part peptone, 0.3 part beef extract, 0.1 part yeast extract, 0.5 sodium chloride Parts, MnSO 4 Copies. H 2 O 0.005 parts, CaCl 2 0.00756 copies, MgSO 4 .7H 2 O 0.05 parts, 99 parts ultrapure water, pH 6.8, autoclaved at 115°C for 30 min;

[0035] ①Expand the seed bacteria, inoculate the bacteria on the slope (such as an inoculation loop) into the test tube containing the lactobacillus culture medium, and incubate at 37°C for 24 hours to obtain the first-level seed bacteria, take it out of the refrigerator and save it for later use;

Embodiment 2

[0050] Example 2 Feeding effect of goslings

[0051] A total of 210 1-day-old Rhine geese with an average weight of 87.35±2.21g were selected and randomly divided into 5 treatment groups according to gender and weight. Each treatment had 3 replicates, and each replicate had 14 young geese, half male and half female. The experiment started at 1 day and ended at 14 days. The diet combination of each group is shown in Table 1.

[0052] Table 1 Experimental grouping and diet combination

[0053]

[0054] The base material is conventional gosling feed sold in the market; the above percentages are weight percentages

[0055] Table 2 Effects of different combinations and dosages on the performance of goslings (g)

[0056]

[0057] Note: The data adopts the mean ± standard deviation; the same row of figures * with ** Indicates a significant level difference between 0.05 and 0.01.

[0058] It can be seen from Table 2 that the daily weight gain, feed intake and feed-to-meat ratio test 4 groups a...

Embodiment 3

[0062] Example 3 Feeding effect of chicks

[0063] In the experiment, 270 1-day-old laying chicks were randomly divided into 6 treatment groups according to sex and body weight. Each group had 3 replicates, each with 15 chicks, and the experiment period was 5 weeks. The diet combination of each group is shown in Table 4.

[0064] Table 4 Experimental grouping and diet combination

[0065]

[0066] The above percentages are percentages by weight

[0067] Table 5 The effect of different combinations and dosages on the performance of chicks (g)

[0068]

[0069] Note: The data adopts the mean ± standard deviation; the same row of figures * with ** Indicates a significant level difference between 0.05 and 0.01.

[0070] It can be seen from Table 5 that in the 1-35 days of age, the daily gain, feed intake and feed-to-meat ratio test of the 8 groups were significantly better than the control group and other test groups ( * p** P<0.01)

Abstract

The invention relates to a micro-ecological synbiotic feed addictive, comprising 10-60 weight parts of micro-ecological probiotics and 40-90 weight parts of oligosaccharide, wherein the viable count of lactic acid bacillus contained in each gram of the micro-ecological synbiotic feed addictive is 0.1-50 billion, the micro-ecological probiotics is a lactic acid bacillus preparation, and the oligosaccharide is one or more of fructo-oligo saccharide, xylo oligosaccharide, isomaltose oligosaccharide and soybean oligosaccharide. Separate application of the additive can raise animal culture production efficiency, reduce feeding cost, enhance the immunity and anti-stress capability of animals, and reduce incidence of diseases. Combined application of the additive and a Chinese herbal medicine additive has significant synergism.

Description

Technical field [0001] The invention relates to the field of animal husbandry, and particularly relates to micro-ecological feed additives. Background technique [0002] With the rapid development of the national economy and the increasing improvement of people's living standards, people have put forward higher and newer requirements for the breeding environment and safe and healthy animal products. As the world’s largest animal breeding country, China’s export of animal products plays an important role in the national economy. However, in recent years, some countries such as Europe and Japan have used food safety issues as barriers to refuse part of the entry of Chinese animal products, causing undesirable effects on the Chinese economy. loss. This series of problems are caused by the "animal product safety" issues, which have become a bottleneck restricting the scientific, healthy and sustainable development of China's aquaculture industry. [0003] In recent years, my country'...
