Problems solved by technology

The long-term use of antibiotics will cause the resistance of pathogenic bacteria, and it will also destroy the micro-ecological balance in the intestinal tract of livestock and poultry, causing endogenous infection or superinfection, resulting in the decline of cellular immunity and humoral immunity of livestock and poultry, so that the production performance is reduced. Impact: Antibiotic residues in livestock and poultry products such as meat, eggs, and milk directly threaten human health and safety, and have adverse effects on public health

Embodiment 1

[0027] Select 320 healthy 1-day-old Aiba Yijia (AA) broilers, with an average body weight of 46±2.5g, and randomly divide them into 4 treatments, each with 8 repetitions, which are control group, test group 1 and test group 2 respectively. and test group 3. The feeding method is caged. The control group and test group 1 were fed with basal rations (refer to American NRC (2012) broiler nutritional requirements, see Table 1 for ration composition), test group 2 was fed with basal ration+300mg / kg honokiol, test group 3 Feed basal diet +300mg / kg magnolol. Experimental groups 1, 2, and 3 challenged broilers with Salmonella pullorum at the age of 7 days (fed with 10 8 CFU / ml Salmonella pullorum nutrient solution 1ml), the test period was 21 days, and the material consumption was recorded and weighed in the test period. After the test, the broiler production performance indicators were determined. On the 14th and 21st days of the test period, one broiler chicken was randomly sele...

Embodiment 2

[0039] Select 400 healthy 1-day-old Aiba Yijia (AA) broilers, with an average body weight of 46±2.5g, and randomly divide them into 5 treatments, each with 8 repetitions, respectively as control group, test group 1, 2, 3 , 4. The rearing method is flat rearing on the ground. The control group was fed the basal diet (refer to the American NRC (2012) broiler nutritional requirements, the diet composition is shown in Table 1), the test group 1 was fed the basal diet + 200mg / kg magnolol; the test group 2 was fed the basal diet +200mg / kg honokiol; test group 3 fed basal diet+0.1% feed additive (components and parts by weight are 10 parts of magnolol, 10 parts of honokiol, 5 parts of sodium butyrate, manna Oligosaccharides 5 parts, 10 10 CFU / g 5 parts of Bacillus coagulans, 1 part of vitamin E, 64 parts of rice husk powder), the test group 4 was fed with basal diet+0.1% feed additive (the components and parts by weight were 10 parts of magnolol, and 10 parts of phenol, 80 parts o...

Embodiment 3

[0046] A total of 1200 45-week-old Jingfen No. 2 healthy laying hens were selected and randomly divided into 4 treatments, with 10 replicates in each treatment, which were respectively the control group and the test group. The control group was fed with basal diet (refer to American NRC (2012) laying hens nutritional requirements, see Table 7), test group 1 was fed with basal diet + 200mg / kg magnolol; test group 2 was fed with basal diet + 200mg / kg honokiol; test group 3 fed basal ration+feed additive (components and parts by weight are 10 parts of magnolol, 10 parts of honokiol, 5 parts of calcium propionate, 5 parts of mannan oligosaccharides , 10 10 CFU / g Clostridium butyricum 5 parts, vitamin E 5 parts, rice husk powder 60 parts). The test period was 12 weeks, and it was carried out in the summer high temperature season (mid-June to the end of August). Feed consumption, daily egg production and total egg weight were recorded during the test period. At the 4th, 8th, and...

Abstract

The invention discloses application of magnolol and / or honokiol in poultry farming, and belongs to the technical field of livestock and poultry farming. Application of magnolol and / or honokiol in daily ration of poultry can promote development of intestinal villi of poultry and increase intestinal villi height and villi / crypt ratio; and adverse effects of common intestinal pathogen infection, stress and the like of poultry on chicken intestines and production performance can be remarkably improved. The invention also discloses a feed additive which takes the magnolol and / or the honokiol as a main component and replaces antibiotics.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding, and in particular relates to the application of magnolol and / or honokiol in feed additives in poultry breeding. Background technique [0002] Since the 1940s, antibiotics have been widely used as feed additives in livestock and poultry farming. It can reduce the diarrhea rate of animals under certain energy conditions, regulate intestinal microbial flora, and inhibit pathogenic bacteria and hosts from competing for nutrients. Thereby improving animal growth performance and feed utilization. [0003] According to statistics, among the feed antibiotics used in the world at present, 42% are used for growth promotion, and only 18% are used for treatment. Abuse of antibiotics is widespread. The long-term use of antibiotics will cause the resistance of pathogenic bacteria, and it will also destroy the micro-ecological balance in the intestinal tract of livestock and poultry, ca...
