Embodiment 1

[0016] Trials are underway in May 2020. The test material is white-feathered broiler chickens, which are fed with the feed containing the extract of Zhishencao, that is, the feed formula of the present invention (Table 1). The white-feather broilers are fed with the formula of the present invention at the age of 26 days, and the feed addition is concentrated in the stage of large chickens. The stage time is from 26-42 days of age. During the period of 26-35 days, feed 5 times a day, the first feeding time is 5:00am, and the interval is 4 hours. During this period, 21:00-22:00 is the dark time when the lights are turned off, and the fifth time is fed after turning on the lights. 36-42 days old are fed 5 times a day, the first feeding time is 5:00am, and the interval is 4.5 hours. The white-feathered broiler chickens were weighed at the age of 35 days, and weighed continuously for 3 days to determine the weight gain of the white-feathered broilers.

Embodiment 2

[0024] To study the effect of the extract of Zhidyceae on the body weight of broilers; Table 1 shows that the broiler chickens in group A were fed with a formula without the extract of Zhidyceae (control group); the broiler chickens in group B were fed with a formula containing 0.15wt% of the extract of Diarrhea; C The broiler chickens in the group were fed with a formula containing 0.2wt% Zhishencao extract; the broilers in group D were fed with a formula containing 0.3wt% Zhishencao extract; the feeding method of each group was the same as that in Example 1. The results are shown in Table 3, the extract of Zhishencao of the present invention obviously improves the age at slaughter and the weight at slaughter of white-feathered broilers.

Abstract

The invention belongs to the technical field of feeds, and particularly relates to a feed for improving the chicken quality of broilers and a use method thereof. The additive comprises the following raw materials in percentage by mass: 50.1%-55.6% of domestic corn, 22%-24.5% of third-grade soybean meal, 0.15%-0.3% of a dysentery fortunei extract, 2%-5% of full-fat soybeans, 5%-6% of yellow flour, 1.4%-2.9% of second-grade rice bran, 0.7% of stone powder, 0.9% of calcium hydrophosphate, 0.4%-0.6% of L-lysine hydrochloride, 3% of a premix, 1% of feather meal, 3%-3.5% of corn protein powder, 2.3%-3% of lard oil and 0.2% of table salt, and the sum of the total mass percentage is 100%. According to the feed, the dysentery fortunei extract is added and is mainly concentrated at a big chicken stage, so that the fat content of the broiler chicken can be effectively changed, the feed conversion ratio is improved, the slaughter weight of the broiler chicken and the oxidation resistance of the chicken meat are improved, and the chicken quality is improved.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed for improving the quality of broiler chicken and a use method thereof. Background technique [0002] With the rapid development of China's fast food industry, the consumption of chicken is increasing year by year, and chicken is delicious and nutritious. Chicken is one of people's favorite foods. It is loved by people for its low price and delicious taste. As the main source of chicken, broiler chickens are raised in large quantities. Broiler chickens are different from laying hens. Broiler chickens are mainly measured by body weight. The same feeding time and Feed amount, the greater the body weight, the higher the benefit. At present, the feed for broiler chickens is mostly supplemented with components containing various nutrients to provide nutrition. At present, in broiler chicken breeding, the feed for large chickens in the short-term fattening process is mos...
