Embodiment 1

[0027] Embodiment 1 Feed of the present invention

[0028] The green tea powder used in the present invention is Lingyun Pekoe, a famous local green tea in Guangxi, which is made by ultrafine grinding in Liuzhou Pharmaceutical Factory, and the particle diameter of the green tea powder is ≤0.075mm.

[0029] Green tea powder contains: tea polyphenols ≥ 20%; caffeine 2%-3%; chlorophyll ≥ 0.35%; protein ≥ 20%; amino acids ≥ 1.0%; Inorganic components such as fluorine 5%-6%; Vitamin C, vitamin B1, vitamin B2, vitamin B6, inositol, folic acid and other vitamins 3%-5%.

[0030] The above-mentioned green tea powder was mixed with the basal rations of two stages shown in Table 1 according to the mass ratio of 0.5%, 0.75%, 1%, and 1.5% to obtain the feed described in the present invention.

Embodiment 2

[0031] Embodiment 2 adopts feed described in the present invention to carry out comparative feeding experiment to Liang Feng chicken

[0032] 1. Experimental process

[0033] 1.1 Experimental animals and grouping

[0034]This experiment adopts single factor randomized block design: 420 1-day-old Liangfeng chicken commercial broiler chickens are selected, male and female are identified, and they are randomly divided into 7 treatment groups (1 control group, 6 test groups). Three replicates were set up for each treatment, with 20 chickens in each replicate, half male and half female. The chickens were weighed one by one after putting on the wing number, and there was no significant difference in body weight between the chicken groups (P>0.05). The test is divided into 2 stages (1-33d, 34d-73d), the whole period is 73d.

[0035] 1.2 Preparation of test feed and diet

[0036] The test diets were added 0, 0.5%, 0.75%, 1.0%, 1.5% green tea powder from the 1st day and 0.75% and 1...

Abstract

The invention provides a feed for improving chicken quality. The feed is prepared by adding 0.5 to 1.5 percent of green tea powder into basic ration. The invention further provides a feeding method for improving the chicken quality of Liangfeng chickens, namely, the Liangfeng chickens are fed by the feed. According to the feed and the feeding method provided by the invention, the fresh and tender degree of the chicken quality of the Liangfeng chickens can be effectively improved without influencing the growth performance of the chickens; the conversion rate of the feed can also be improved to a certain degree; the feeding cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a feed and a feeding method for improving the quality of chicken. Background technique [0002] The main active ingredient of green tea is tea polyphenols, accounting for about 20%-30%, and also contains caffeine, tea pigment, amino acids, vitamins, methylated xanthine derivatives, theophylline, theobromine and other biologically active substances , many varieties and high content, with extremely high nutritional value and pharmacological value. Coupled with the special properties of ultrafine powder, such as surface effect, volume effect, quantum effect, tunnel effect, etc., ultrafine particles have different biological activities from macroscopic substances. Its good absorption and dispersibility can improve the activity and bioavailability of nutrients, while reducing the amount of functional substances added to food and feed. [0003] At present, in the existin...
