Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the tables in the embodiments of the present invention:

[0021] 1. The effect of acetic acid on the digestive performance of large-bone chickens

[0022] 1. Experimental animals, feeding management and experimental design

[0023] Select 48 1-day-old Liaoning Zhuanghe big-bone chickens, half male and half female, and randomly divide them into a control group and an experimental group. Add 0.5% acetic acid to the basal diet. At the 15th day of the experiment, four test chickens (half male and female) were slaughtered and blood samples were collected from the two groups of test chickens. They were left to stand for 15 minutes and centrifuged at 3000 r / min for 10 minutes. The supernatant was divided into 1.5 mL EP tubes, and stored in a refrigerator at -20°C for the determination of serum indicators. At the same time, 2 roosters and 2 hen...

Abstract

The invention discloses compound green feed additive for improving immunity of broiler chickens and feed conversion ratio. The compound green feed additive is prepared by: subjecting dried cortex mori(CM) to pulverizing and ultrasonic extracting, carrying out vacuum filtration, collecting filtrate, carrying out vacuum distillation on the filtrate to be concentrated to viscous state, cooling the concentrated filtrate to room temperature, adding anhydrous ethanol, putting the mixed solution in a sterile environment for standing, carrying out filtering to separate precipitates from the solution,and drying the precipitates to a constant weight; and adding 1 part of acetic acid and maltodextrin into 5 parts of polysaccharide isolated from cortex mori (CMP) with a need of continuous stirring in the process of adding the maltodextrin until the total mass of the mixture is 10 parts, thereby obtaining the compound green feed additive. The compound feed additive can improve the immunity of thebroiler chickens and the feed conversion ratio, thereby avoiding the overabuse of antibiotics as the feed additive and a series of problems on the safety of livestock and poultry products.

Description

technical field [0001] The invention relates to the field of broiler chicken breeding, in particular to a compound green feed additive for improving the immunity and feed utilization rate of broiler chickens. Background technique [0002] In order to promote animal growth and maintain animal health, antibiotics have been excessively abused as feed additives, resulting in a series of safety problems in livestock and poultry products, and even induced drug-resistant strains. Therefore, it has become an issue of increasing concern to find safe and side-effect-free alternatives to antibiotics used in livestock and poultry production. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned existing problems, provide a compound green feed additive that improves broiler immunity and feed utilization, and solve the problem of excessive abuse of antibiotics as feed additives, resulting in a series of livestock and poultry problems. p...
