Problems solved by technology

[0003] The traditional animal blood sampling method is no longer suitable for monitoring the physiological status of the changes in the immunoglobulin content of brown-eared pheasant chicks. It is urgent to explore and develop a simple, fast, and non-invasive method for judging the physical condition of brown-eared pheasant chicks. brood grouping in rearing

Embodiment 1

[0049] Example 1. Determination of critical IgA content in the health status of brown horse chicken chicks using feces as the sample to be tested

[0050] 1. Grouping and breeding of brown horse chicken chicks to be tested

[0051] The brown horse chicken chicks artificially hatched in Pangquangou Nature Reserve from May to September 2011 were taken as the research object. From May 24 to June 12, 103 eggs from 9 litters in the wild hatched 93 chicks, with a hatching rate of 90%. For the determination of IgA content, 30 chicks hatched on May 29, from 3 litters, were divided into group A (14), group B (7), and group C (9). When the chicks are 2 days old, they are marked with a colored steel ring. The steel ring weighs 0.8g and is replaced every 30 days thereafter.

[0052] The chicks are 1 to 35 days old. The hens raised in the reserve will bring their chicks, and they will be reared in the chicks rearing room on a litter basis, providing sufficient chick feed and the same room tempe...

Embodiment 2

[0086] Example 2. Breeding and brooding test of brown horse chicken

[0087] Two-year brown horse chicken breeding brood grouping trial in 2011 and 2012

[0088] 1. Raising of 2~4 day old chicks

[0089] Experimental animals and groupings: 60 2- to 4-day-old brown horse chicken chicks artificially hatched from Pangquangou Nature Reserve were randomly divided into two groups, 45 in the experimental group and 15 in the control group.

[0090] Experimental group: According to the method described in Example 1, the content of IgA in the feces of brown horse chicken chickens in the experimental group was determined. According to the content determination results, referring to the results of the Euclidean distance systematic clustering analysis of the IgA content in the feces of the 3-day-old brown horse chicken chicks in step 6-3 of Example 1, the 60 2--4 day-old brown horse chicken chicks were divided into the following three groups , Isolate breeding between groups:

[0091] Group A: 20 ...

Abstract

The invention discloses a method for judging physical conditions of brown-eared pheasant chickens through a non-invasive sampling method and for grouping feeding, in particular to a brown-eared pheasant brooding method. According to the brown-eared pheasant brooding method, the brown-eared pheasant chickens to be bred are grouped and isolated for being fed according to the different contents of immune globulin A in excrement. Experiments prove that the healthy conditions of the brown-eared pheasant chickens can be evaluated through monitoring of the contents and the changes of the immune globulin A in the excrement of the brown-eared pheasant chickens, and the method is an ideal non-invasive method. When the method is used in the brood process of brown-eared pheasants, and the chickens are grouped and isolated for being fed according to the contents of the immune globulin A in the excrement of the chickens to be bred, results show that compared with comparison groups which are allocated in a random mode, the feeding method greatly lowers the death rate of the chickens for the whole chicken group.

Description

Technical field [0001] The invention relates to a method for judging the physical condition of brown horse chicken chicks and brooding and grouping during breeding, in particular to a method for brooding brown horse chickens. Background technique [0002] The brown horse chicken (Crossoptilon mantchuricum) is a rare and endangered bird unique to China and a national first-class protected animal. Due to the fragmented habitat and population isolation of this species, it has led to degradation of fecundity and population decline. The World Conservation Union (IUCN), the International Union of Birds (BirdLife), and the Public Utilities Agency (WPA) list it as a globally endangered species. The Convention on International Trade in Endangered Wild Fauna and Flora (CITES) is listed in Appendix I. Detecting and assessing the survival status of rare and endangered species, and implementing necessary manual management and protection, is a key link in ensuring the health quality of breedi...
