Problems solved by technology

However, the high temperature in summer is a kind of heat stress for laying hens, which leads to a decrease in feed intake, a decrease in the utilization rate of feed nutrients, a body weight that cannot meet the requirements of the standard egg production rate, and a decline in the immune function of the body, which not only affects production The amount of eggs will reduce the egg weight, the eggshell will become thinner, the egg quality will decrease, and it will affect the disease resistance of laying hens

Embodiment 1

[0022] Experiment 1 was carried out in the same closed-type wet curtain ventilation chicken house in the farm of Huafeng Breeding Professional Cooperative in Yixing City. The experimental chickens were Hailan brown commercial laying hens. The time is from May 1st to August 31st, 2012. The distribution of maximum daytime temperature in Yixing City from May 1, 2012 to August 31, 2012 is shown in Table 1. The entire test period was 123 days, and the time when the temperature was higher than 30°C reached 75 days.

[0023] 2000 Hailan brown commercial layer hens were divided into 4 groups, control group, experimental group 1, experimental group 2 and experimental group 3, with 500 chickens in each group. The feed formula of each group is as follows:

[0024] Chinese herbal medicine mixed additives: weigh astragalus, angelica, epimedium, privet privet, wolfberry, hawthorn, motherwort, mint and licorice, and the mass ratio of each component is 1:1:2:1:3:1:1:1 : 0.5; after each comp...

Embodiment 2

[0039] Experiment 2 was carried out in the same closed-type wet-curtain-ventilated chicken house in Yuda Ecological Agriculture Chicken Farm in Yixing City, and the test chickens were Roman brown commercial laying hens. The time is from May 1st to August 31st, 2012. The distribution of daytime maximum temperature in Yixing City from May 1 to August 31, 2012 is also shown in Table 1.

[0040] 2000 Roman brown commercial laying hens are divided into 4 groups, each group of 500, the specific method is the same as embodiment one.

Abstract

The invention discloses feed for improving production performance of laying hens in a high temperature season and a breeding method. The method comprises the following steps of: adding 0.5-2.5 percent of soybean oil into a formula of normal laying hen feed for performing equivalent replacement on corn in the formula of normal laying hen feed, adding 50-200mg of Chinese herbal medicine mixed additive subjected to superfine grinding into the feed per kg, wherein the Chinese herbal medicine mixed additive comprises astragalus, Chinese angelica, herba epimedii, glossy privet fruit, wolfberry, hawthorn, motherwort, mint and liquorice. Therefore, the eggshell thickness of the laying hen can be increased by 8.3-8.6 percent, the Haugh unit is improved by 3.2-3.5 percent, the eggshell strength is improved by 22.1-32.9 percent, the egg breakage rate is reduced by 3-4 percent, the feed utilization rate is improved by 7-8 percent, the high-temperature period death rate of the laying hen is reduced by 1-3 percent, and the laying hen is bright in feather color and gloss.

Description

Technical field: [0001] The invention relates to the field of poultry production, in particular to a feed and a breeding method for improving the production performance of laying hens in high temperature seasons. Background technique: [0002] The breeding quantity of layer hens in my country ranks first in the world, the breeding quantity of commercial layer hens is about 1.5 billion, and the egg production accounts for more than 40% of the world. Most of the provenances of laying hens currently raised are imported from abroad, and the feeding methods and dietary formulas have been relatively stable. However, the high temperature in summer is a kind of heat stress for laying hens, which leads to a decrease in feed intake, a decrease in the utilization rate of feed nutrients, a body weight that cannot meet the requirements of the standard egg production rate, and a decline in the immune function of the body, which not only affects production The amount of eggs will reduce t...
