Embodiment 1

[0044] Embodiment 1, the preparation of fermented wormwood

[0045] 1. Select the crushed whole plant wormwood, and pass through a 60-mesh sieve after crushing. The probiotics were purchased from the General Microbiology Center (CGMCC) of China Microbiological Culture Collection Management Committee (CGMCC), Lactobacillus casei (Lactobacillus casei, strain number 1.2884) was cultured with MRS medium, Candida utilis (Candida utilis, strain number 2.0615) ) was cultured with YPD medium, and Bacillus subtilis (Bacillus subtilis, strain number 1.0504) was cultured with LB medium, and the viable counts of the three bacteria were adjusted to 1.0×10 6 CFU / mL, 1.0×10 7 CFU / mL and 1.0×10 6 CFU / mL, the three kinds of probiotics are mixed according to equal volume ratio to prepare compound probiotics. Cellulase was purchased from Shandong Zesheng Biotechnology Co., Ltd., and the enzyme activity of the filter paper was 130 FPU / g.

[0046] The test adopts solid fermentation, and is div...

Embodiment 2

[0058] Embodiment 2, production performance

[0059] 1. Weigh the animals on 1d, 21d, and 42d respectively, and record the feed intake of each repetition every day. Record the diarrhea and death status of each repeated chicken. Calculate average daily feed intake (ADFI) and average daily gain (ADG). And calculate feed conversion ratio and diarrhea rate, diarrhea rate=total diarrhea days / (total number of chickens×test days).

[0060] 2. The effect of different treatments of wormwood feed on the growth performance of broiler chickens. It can be seen from Table 3 that in the early stage of the broiler chicken experiment, adding wormwood and fermented wormwood to the broiler feed reduced the diarrhea rate of broilers, and adding 3% fermented wormwood D group works best.

[0061] Table 3. Effects of different treatments of wormwood feed formulations on the growth performance of 1-21d broiler chickens (g)

Embodiment 3

[0067] Embodiment 3, the mensuration of nutrient digestibility

[0068] 1. Use the method of collecting manure completely, and collect excrement on 19-21d and 40-42d respectively (record feed intake and excretion for 3 days). Mix the feces samples every day to remove impurities, add 10% hydrochloric acid to fix nitrogen, and store them in a -20°C refrigerator. After the test, mix the feces samples for three days and dry them at 65°C. CP): adopt national standard CB / T6432-94; crude fat (EE): adopt national standard GB / T6433-2006; calcium (Ca): adopt disodium edetate complexometric titration method; phosphorus (P): adopt national standard GB / T6437-2002.

[0069] 2. The effect of bacterial enzyme combined treatment with wormwood on the nutrient digestibility of broilers

[0070] It can be seen from Table 5 that in the early stage of broiler feeding, adding 3% fermented wormwood (group D) to the feed significantly improved the digestibility of crude protein and crude fat (P<0.05...

Abstract

The invention discloses application of fermented wormwood in preparation of a product for improving production performance and antioxidant capacity of broiler chicken. The application of the fermentedwormwood in any one of the following steps: preparing a product for reducing diarrhea rate of the broiler chicken; preparing a product for reducing feed-weight ratio; preparing a product for improving digestibility of crude protein and crude fat; preparing a product for reducing digestibility of crude protein in feed; preparing a product for improving tenderness and color of breast muscle and legmuscle of the broiler chicken; preparing a product for improving total antioxidant capacity of the broiler chicken; preparing a product for enhancing the digestive ability of the broiler chicken to the feed; preparing a product for reducing the depth of intestinal crypt of the broiler chicken; and preparing a product for improving the fluff arrangement of the broiler chicken. Tests show that by adding the fermented wormwood rich in probiotics and antioxidant active ingredients in a proper proportion into a broiler chicken feed formula, the production performance of the broiler chicken can beimproved, the intestinal health and antioxidant capacity of the broiler chicken are promoted, the meat quality is improved, and the fermented wormwood has high application value and market prospect.

Description

technical field [0001] The invention relates to the technical field of biological feed preparation, in particular to the application of fermented wormwood in the preparation of products for improving the production performance and antioxidant capacity of broilers. Background technique [0002] Artemisia argyi (Artemisia argyi) is a perennial herb of the genus Artemisia in the Asteraceae family. It is a traditional Chinese medicine in my country and has unique medicinal and health care values. Wormwood and wormwood powder also have certain applications in animal production. Previous studies have shown that adding a certain amount of wormwood powder to pig and chicken feed can promote growth and health care, but wormwood has a high fiber content and has a special smell. Excessive feeding affects the digestion and utilization of monogastric animals. Compound probiotics and enzyme fermented wormwood can increase the content of active antioxidant components in wormwood, rich in ...
