Embodiment 1

[0059] Compare the influence of extraction time on the solid content of the extract to determine the most optimal extraction time:

[0060] The process (extraction time described in step ③ in the preparation method) was determined by using fresh Pinus massoniana pine needles collected from Deqing Mountain, Zhejiang Province as raw materials.

[0061] Take five parts of the same number of fresh masson pine pine needles, remove other leaves, silt, and wash. First twist the pine needles into small sections of 1-5cm with a guillotine, control the ratio of pine needles to water at 1:3, smash and refine. Obtain the filtrate for the first time respectively, and set aside. Each filter residue is then extracted with 1:3 water, the extraction temperature is controlled at 80-100°C, the extraction time is 0, 30 minutes, 60 minutes, 90 minutes, 120 minutes respectively, and then filtered to obtain the second filtrate. The filtrates were combined twice and concentrated under normal pressu...

[0064] Preparation of Feed Additives Using Fresh Masson Pine Needles Collected from Deqing Mountain, Zhejiang Province as Raw Materials

[0065] Take fresh masson pine needles, remove other leaves, sediment, and wash. First, twist the pine needles into small sections of 1-5cm with a guillotine, add an appropriate amount of water in a certain proportion, break and refine. The ratio of pine needles and water can be controlled at 1:3, and the first filtrate is obtained respectively for subsequent use. Each filter residue is then extracted with 1:3 water, the extraction temperature is controlled at 80-100° C., the extraction time is 60 minutes, and then filtered to obtain the second filtrate. The two filtrates were combined and concentrated under normal pressure to obtain a tan viscous liquid. The pine needle water extract can be used as a feed additive.

Embodiment 3

[0076] Observe the effect of pine needle extract on the growth-promoting effect and disease resistance of broiler chickens:

[0077] Test with the pine needle extract prepared in Example 2, and use 1-day-old "Zhijianghuang" for broiler chickens. The tested strains were Salmonella resistant to 30ppm kanamycin and 5ppm ampicillin. The feed is full-price compound feed for chicks (see Table 1), without adding any antibiotics and anticoccidial drugs. The broiler chickens used in the test were divided into two groups: the control group (without adding pine needle extract group) and the group adding 2‰ pine needle extract, each group was 40 chickens, and the pine needle extract was mixed into the feed for feeding. 2-day-old challenge Salmonella 3 x 10 7 cfu / feather, weigh and detect Salmonella at the age of 9 days and 15 days respectively, and the detection method of Salmonella refers to the national standard (GB13091-91).

Abstract

A feed additive for increasing the resistance of animal to diseases is prepared from the fragments of the plants in pinaceae through pulverizing and extracting in hot water. Its contains polyphenol compound and polyose for regulating the balance between floras in animal's intestinal tract.

Description

1. Technical field [0001] The invention relates to a feed additive, especially a feed additive containing polyphenolic compounds, glucose, mannose, xylose, and arabinogalactose extracted from plant fragments of the genus Pinus in the family Pinaceae. The feed additive is prepared and produced The method and the purposes of this feed additive. 2. Background technology [0002] It is now recognized that an imbalance in the intestinal flora of animals is one of the causes of diarrhea in animals. If pathogenic microorganisms in the intestine, such as Escherichia coli, Salmonella, etc. reproduce in large numbers, or spoilage bacteria grow in large quantities, it will cause a decrease in the number of beneficial bacteria, such as Bifidobacteria and Lactobacillus, which can easily lead to diarrhea in animals. The conventional method to treat diarrhea in animals is to feed animals with antibiotics, but the long-term abuse of antibiotics not only weakens the disease resistance of th...
