As previously mentioned, records of animals identified are the only means of tracing diseased animals to the location where they were tagged. It is imperative, therefore, that orderly records of animal identification be maintained in a safe location. Accredited veterinarians may return the unused tags to the district office if they do not expect to use them anymore in the future.
The return of these tags must be indicated in the record. Tags approved under the TRACE program are issued and records are maintained by responsible administrators.
Chapter 2 - Identification 2. Search for related documents in the Guidance Document Repository This section describes the general identification procedures for livestock, official Identification, and record keeping.
The following information should be recorded: Three official animal identification systems have been approved by the CFIA: Tags or indicators approved or considered equivalent under the Livestock Identification and Traceability TRACE program; Health of Animals HofA ear tag for species not covered by mandatory national identification requirements; legible registered tattoos. Bovine and bison must be identified with an electronic RFID ear tag which bears a unique number that follows the International Organization for Standardization ISO standard format, i.
The first three digits is the country code: For more information, please consult module 5. Ovine must be identified with tags that follow the ISO standard. These tags may be electronic RFID or non-electronic. Porcine may be identified with tags or other indicators tattoo.
Ear tags that meet the ISO standard are mandatory for swine intended for admission into a semen collection centre. For export purpose, requirements of both the national program and the country of destination will need to be met. These requirements are dependent on the country or state of destination and the end use of the animal breeding or fattening. Please refer to the appropriate export section for more details.
HofA Ear Tags 5. Ensure that the proper size is used. Ear tags are available to accredited veterinarians through CFIA district offices. Ear tags should be placed in the proximal third of the anterior border of the animal's ear. The alpha-numeric sequence must face "out. When inserting an ear tag, always leave a small space between the edge of the ear and the outer margins of the tag.
The district veterinarian will demonstrate the proper technique if clarification is required. The estimated breeding value indicates the value of the animal with respect to the breeding goal: Fifth, given the estimated breeding values of sires and dams, the actual selection of parents has to take place 5. The parents with a higher than average estimated breeding value will improve the breeding goal traits in the next generation.
When for example a group of dairy sires with the highest breeding value for milk yield is selected as sires for the next generations, their daughters will produce more milk than the present generation of dairy cows.
Proper selection of parents will give a positive selection response in the next generations. Selection creates progress in breeding goal traits.
After the selection of the parents another choice has to be made: The choice can be made e. Sixth, in many breeding schemes the number of animals from which traits are recorded is rather small in relation to the population of animals used for human purposes.
The dissemination of the selection response depends of the structure of the breeding programs. In cattle breeding artificial reproduction techniques, in particular artificial insemination techniques, give the opportunity to produce high numbers of offspring, disseminating the genes of the superior animals widely. Selection of a small number of animals may have a large impact on the traits of a population. Within the commercial breeding schemes e. These lines each are selected for specific traits and crossed in the multiplying phases to obtain crossbred progeny with the breeding goal traits by combining the traits of each of the lines.
Seventh, the breeding program should be evaluated regularly 7. The first question is: Is the new generation of animals better with respect to the breeding goal traits? Do we observe unwanted effects of selection? The second question is: Are they more related to each other than their parents, due to the fact that we have selected only a few heavily related animals as parents for this generation?
Did we decrease the genetic diversity of the population? Then, the breeding circle starts again with a critical review of changes in the production system. Questions to be answered are: Do production circumstances change, e.

2.1 Animal Population
Identification of Livestock (updated January ) In the case of purebred animals, the information on the registration/pedigree. First, the set up starts with a description of the production system (1). In more general terms the analysis of the way we keep the animals and for which purpose . Animals. Treatment groups. For the dose-response study, 40 week old C57/Bl6 wild type male mice (The Jackson Laboratory) were subjected to.
