Problems solved by technology

[0004] Or for medium-sized laying hens that are currently overweight or fat, because their feeding technology requirements are stricter than light laying hens, if there is a slight negligence in feeding management, satisfactory egg production performance cannot be obtained (Dong Shumin. Purpose and method of feeding restriction[J]. Animal Husbandry and Veterinary Science and Technology Information, 2016(12): 35.)
[0005] However, there is no relevant report on how to restrict feeding of laying hens, how to screen and determine the most suitable method of restricting feeding

Embodiment

[0029] A research method for feeding during the breeding period of laying hens, comprising the following steps:

[0030] 1. Select 1,300 1-day-old Suqin green-shell parental hens from the same batch of breeders, wear wing numbers, weigh at birth, and feed them to 6 weeks of age. From 0 to 6 weeks old, they had free access to food and water, and routine feeding and management. At 6 weeks of age, 1080 hens with good body condition and similar body weight were selected.

[0031] 2. 1080 hens were randomly divided into 6 groups with 6 repetitions in each group and 30 chickens in each repetition. From 6 to 15 weeks old, the laying hens in the control group were fed ad libitum, while the other 5 groups were fed 90%, 85%, 80%, 75% and 70% of the ad libitum intake, respectively. After 15 weeks of age, they were transferred to individual egg-laying cages in units of repetitions, and all chickens were fed freely and managed in a unified manner. The diet composition and nutritional le...

Abstract

The invention belongs to the technical field of poultry breeding, and in particular relates to a research method for laying hens to be fed during the breeding period. The method of the invention takes the population uniformity as the first limiting factor, and determines the pros and cons by comprehensively analyzing the variation coefficient of each week age; taking the body weight as the second limiting factor, in order to ensure that the laying hens reach body maturity before sexual maturity without affecting the production The length of the egg cycle, choose the feeding restriction program that requires no significant difference in body weight after ad libitum feeding and the ad libitum feeding group. According to two limiting factors, determine the most suitable feeding restriction that can improve the uniformity of laying hens in the early stage of laying. method.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a research method for laying hens to be reared and termed feed. Background technique [0002] Restricted feeding is one of the important means of feeding and management of laying hens. It is an effective method to artificially control the feeding amount and limit the energy and crude protein level of chickens in the diet, so as to improve the egg production of chicken farms. [0003] At present, most of the research on chicken feed restriction focuses on broiler breeders. For example, Wang Qianbao et al. studied the effects of different crude protein levels on the production performance, reproductive performance and egg quality of broiler breeders by means of feed restriction. A total of 240 broiler breeder S3 hens at 25 weeks of age with the same body weight and egg production rate were selected and randomly divided into 4 groups with 6 replicates in each gr...
