Embodiment 1

[0017] Example 1: Effects of different feed additives on growth performance and immunity of weaned piglets

[0018] 1. Experimental design

[0019] In the experiment, 96 healthy, 25-day-old weaned piglets (Du×Long×Da) with the same weight (about 6.0kg) were selected and randomly divided into 4 treatment groups, each treatment group had 6 repetitions, and each repetition had 4 piglets. for 28 days. Wherein group A is the control group, fed with basal rations; group B added plant essential oil (40% content) feed additive 400g / t on the basis of basal rations; group C added the present invention on the basis of basal rations Intestinal-protecting feed additive 300g / t; D group added 400g / t of intestinal-protecting feed additive of the present invention on the basis of basal diet, see Table 1 for details.

[0037] 1. Test method

[0038] 960 1-day-old white-feathered broiler chickens were selected for the test, and they were randomly divided into 4 groups for treatment, with 12 repetitions in each group and 20 birds in each repetition. The test lasted for 42 days. Wherein group A is the control group, fed with basal diet; group B has added plant essential oil (40% content) feed additive 300g / t on the basis of basal diet; group C has added the present invention on the basis of basal diet Intestinal-protecting feed additive 200g / t; D group added 300g / t of intestinal-protecting feed additive of the present invention on the basis of basal diet, see Table 5 for details.

[0053] Example 3: Effects of different feed additives on growth performance and intestinal microorganisms of yellow-feathered broilers challenged with Clostridium perfringens

[0054] 1. Test method

[0055] A total of 384 1-day-old yellow-feathered broilers were selected for the experiment, and were randomly divided into 4 groups according to the principle of no difference in body weight. Each group had 8 replicates, and each replicate had 12 broilers. Wherein group A is the control group, fed with basal diet; group B has added plant essential oil (40% content) feed additive 300g / t on the basis of basal diet; group C has added the present invention on the basis of basal diet Intestinal-protecting feed additive 200g / t; D group added 300g / t of intestinal-protecting feed additive of the present invention on the basis of basal diet, see Table 8 for details. From the 26th to the 30th day of the test, 2 mL of Clostridium perfringens culture solution was fed for 5 consecutive days ...

Abstract

The invention discloses a plant extract additive for improving intestinal health of livestock and poultry, and belongs to the field of feed additives. Intestinal tracts are digestion and absorption places of livestock and poultry nutrient substances, intestinal tract damage certainly causes diarrhea, diarrhea and the like, the phenomena of low feed conversion rate, reduced growth performance and the like are caused. The plant extract additive comprises the following main components: 10-30 parts of a plant essential oil compound, 10-30 parts of plant polysaccharide, 10-20 parts of medium and short chain fatty acid and 50-70 parts of a carrier, wherein the plant essential oil compound is prepared by mixing one or more of cinnamyl aldehyde, thymol, carvacrol, eugenol and allicin according to a specific proportion; the plant polysaccharide is prepared by mixing one or more of astragalus polysaccharide, ganoderma lucidum polysaccharide and gingko polysaccharide according to a specific proportion; and the medium and short chain fatty acid is prepared by mixing one or more of caprylic acid, capric acid and lauric acid according to a specific proportion. Breeding test results show that the plant extract compound feed additive has the functions of obviously improving intestinal flora structures of the livestock and poultry, promoting intestinal villus development and the like besides remarkable anti-inflammation and sterilization effects. The feed additive has the characteristics of wide antibacterial spectrum, difficulty in generating drug resistance, no pollution to the environment and the like, can effectively kill harmful bacteria in intestinal tracts of livestock and poultry, also has the effects of promoting intestinal villus development, intestinal barrier repair and the like, improves the digestion and absorption of organisms on nutrient substances, enhances the disease resistance of flora and improves the breeding benefits of the livestock and poultry.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a plant extract additive for improving intestinal health of livestock and poultry. Background technique [0002] At present, intestinal problems are still a major problem restricting the development of the breeding industry. The intestinal tract is the main place for livestock and poultry to digest and absorb nutrients. Therefore, the health of the intestinal tract is very important for feed intake and digestion and absorption of nutrients. Intestinal health mainly depends on a complete intestinal morphological structure, a relatively stable microbial ecosystem and the body's immune regulation system. According to reports, about 70-80% of the antibiotics used in the livestock and poultry breeding process in my country are used to prevent or treat digestive system diseases. Therefore, ensuring the body's intestinal health is one of the key ways to reduce the use of antibiotics in ani...
