Embodiment 1

[0075] Embodiment 1: Effect of feed formula on production performance of green-shell laying hens

[0076] Effects of Feed Green Tea Powder on Egg Production Rate

[0077] In this experiment, the egg production rate tended to increase gradually with the increase of the amount of green tea powder added for feeding. Wang Xuexin introduced: Tea contains B vitamins, Vc, VD, glucose, lactic acid, theophylline, caffeine and other substances. Layers are fed with 5ml each time and twice a day. %. Luo Xianhui and others added 1% tea powder to the diet of laying hens. After 110 days of experimentation, the egg production rate increased by 16.8% compared with the control group. Wang Renyue's experiment showed that when green tea powder was added to the diet, the addition of 500mg / kg green tea powder increased the egg production rate in the whole period by 1.67 percentage points compared with the control group (p>0.05). Yin Jingdong reported that adding 40mg / kg of tea polyphenols to lay...

Embodiment 2

[0081] Example 2: Effect of feed formula on conventional egg quality of green-shell laying hens

[0082] The effect of feeding green tea powder on the average egg weight

[0083] Egg weight is an important index for grading fresh eggs. Within the normal egg weight range, the larger the egg weight, the higher the grade. It is affected by factors such as breed, age, stage of sexual maturity, environment, certain medications, and nutrition.

[0084] In this experiment, the average egg weight was slightly decreased by feeding green tea powder, but there was no significant difference among the groups (P>0.05). This is different from the report of Yin Jingdong et al., that adding tea polyphenols can increase the average egg weight of the test group. In this experiment, the average egg weight tends to decrease, and the analysis suggests that the decrease in average egg weight may be related to the increase in egg production rate.

Embodiment 3

[0094] Embodiment 3: Feed formula influences the content of cholesterol in egg yolk of green-shelled eggs

[0095] Tea polysaccharides in tea polyphenols have high blood fat-lowering, blood-sugar-lowering, anti-coagulant, anti-thrombosis and other effects.

[0096] Experiments by Zhu Xiangming and others showed that tea polyphenols can inhibit the increase of quail serum total cholesterol, triglyceride and low-density lipoprotein levels. Zhang Hongfeng et al. tested on quail that tea polyphenols have a strong effect of lowering blood fat and anti-fatty liver. Yin Jingdong's experiments on chickens showed that adding tea polyphenols to the diet significantly reduced the levels of plasma triglycerides, total cholesterol and low-density lipoprotein cholesterol (P<0.05). Qi Guanghai et al. added 5, 10, 20, and 40 mg / kg tea polyphenols to the rations of brown-shell Hesek laying hens for 28 weeks. Cholesterol levels in egg yolk, breast muscle and liver also decreased to varying de...

Abstract

The invention discloses a feed for producing low-cholesterol green-shell eggs. The feed comprises the following components: 63 parts of corn, 14 parts of bean pulp, 4.5 parts of wheat bran, 8 parts of mountain flour, 8 parts of source peptide, 2.5 parts of premix and 0.4-1.2 part of green tea powder. According to the technical scheme of the invention, the green tea powder for feeding is added in daily ration of green-shell egg chickens, so that the digestive absorption and utilization of the egg chickens to nutrient substances are improved, the production efficiency can be improved, the egg quality can be improved, and green healthy low-cholesterol eggs can be produced. The feed for producing low-cholesterol green-shell eggs is suitable for the field of poultry farming technologies.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and relates to a feed, in particular to a feed for producing low-cholesterol green-shell eggs. Background technique [0002] With the continuous deepening of people's understanding of tea and the application of ultrafine pulverization technology in tea processing, tea products are gradually applied to many fields of life and production, especially in animal husbandry and feed processing. But the application of green tea powder in animal husbandry, especially in poultry industry, except for a small amount of research in Japan, there are few related researches at home and abroad. [0003] The functionality of tea is the result of the comprehensive action of various ingredients in tea, and the leading role is tea polyphenols, which account for 25% of the weight of dry matter in tea, and dietary fiber in tea. In recent years, the research of a large number of scientists at home and abroad h...
