Basic types of establishments for animal keeping are breeding / supply establishments and user establishments. The number of animals can only be approximated in advance because it is impossible to predict the exact number and sex of offspring. In natural mating a breeding male is actually used for mating with the females. Programming was in Fortran because Fortran programs are relatively easy for numerical problems, and many existing packages in animal breeding still useful at that time were written in Fortran. Stephen A. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has revolutionized livestock production throughout the … Use of Laboratory Animals in Biomedical and Behavioral Research (1988) Animals for Research: A Directory of Sources, Tenth Edition and Supplement (1979) Amphibians: Guidelines for the Breeding, Care and Management of Laboratory Animals (1974) Copies of these reports may be ordered from the National Academies Press (800) 624-6242 or (202) 334-3313 The reproductive system of the fowl, however, differs in form and function from the other domestic animals covered in this lesson. Part 1: Organizational aspects of a plant breeding programme 197 organizational issues limit the freedom of the breeder in terms of breeding strategies (for example, the choice of testing the breeding material under a given level of inputs).

Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. %%EOF Genetic evaluation of individual animals in a breeding population, selection of the best individuals for traits of importance in some sense (adaptation, production, economic), followed by mating of selected individuals to generate the next generation of animals. The number of animals can only be approximated in advance because it is impossible to predict the exact number and sex of offspring. Animal breeding the modern approach : a textbook for consultants, farmers, teachers and for students of animal breeding, Keith Hammond, Hans-Ulrich Graser, Alex McDonald, 1992, Animal breeding, 257 pages. 2. Furthermore, processes 3 The various techniques for altering the genetic make-up of an animal are explained in the report. appropriate breeding schemes, weaning ages, and methods for identification of individual animals.

The health and well-being of the animals depend on the care, human attitude of the animal-keepers (staff) of the animal house. animal products such as urine, dander and serum by using long-necked, non-allergic gloves, laboratory coats and adequate respiratory protective equipment, (b) avoidance of wearing street clothes while working with animals as well as (c) leaving work clothes at the workplace, should be taken. This monograph will focus only on agricultural crop biotechnology. quantitative and molecular breeding methods. The domestic mouse, Mus musculus and related subspecies (see Mice and Rats as Laboratory Animals), is popular as a mammalian research model because of its small size, adaptability, docility, low husbandry costs, fecundity, well-defined health and genetic backgrounds, and relative ease of genetic manipulation.The development of genetic engineering techniques of inserting … Several sections of the guidelines have yet to be finalised, but the Councils are now issuing those relating to housing and care of laboratory animals. Animal breeding, controlled propagation of domestic animals in order to improve desirable qualities. Selective breeding involves using knowledge from several branches of science. Some, such as selective breeding or exposure to Artificial insemination (AI) and embryo transfer (ET) are commonplace in conventional animal breeding. �|ÚŸT³MÙ ³cä$60qzòş�j¦#§â�¾2B©’�Ÿ6�e~¤à'×wÀ¬ù‡Ğ–ì0œO‘¦î�ó¨è :†&�¤š8��M>x �N:?ôÑæ°ÏT¤×éP=‚bÙ%M%ß …Ú“.

OBJECTIVES To provide basic concept of animal handling to new user. Genetic evaluation of individual animals in a breeding population, selection of the best individuals for traits of importance in some sense (adaptation, production, economic), followed by mating of selected individuals to generate the next generation of animals. But these techniques are 'artificial' and they deprive animals of natural mating behaviour and negatively affect the animals' welfare and integrity. Hundreds of animals may be 'created' in an attempt to obtain a transgenic individual with a particular desired set of traits. The primary enclosure provides the limits of the animal’s immediate environment. %PDF-1.6 %���� In natural mating a breeding male is actually used for mating with the females. .

Th ese techniques have been developed and used by Th e Jackson Laboratory for over 75 years. Testicles – As in the other animals, sperm and hormones are produced in the testicles. The other method is artificial insemination. Section 1 Animal Welfare Considerations J.S. But these techniques are 'artificial' and they deprive animals of natural mating behaviour and negatively affect the animals' welfare and integrity. Methods. Estimates of repeatability obtained from this study were 0.29, 0.26, 0.22, 0.38, 0.41, and 0.74 for BWs of chickens at 1 day, 4, 8, 9, 10 and 16 weeks of age respectively (Table 9). The most important item on a rodent breeding bin is the cage ID/breeding record card. Inbreeding may be explained by taking an example of cows and bulls. Mouse stocks and breeding methods were as de-scribed by Bruce & Emmens (1948). Laboratory animals in most countries are protected by the Law “Cruelty to Animals Act”. Inbreeding: When breeding is between animals of the same breed for 4-6 genera­tions, it is called inbreeding. Agricultural biotechnology is the term used in crop and livestock improvement through biotechnology tools. Animal Breeding Principles and Practice in the Philippine Context, Orville L. Bondoc, 2008, Science, 386 pages. III. domestic animals (2). females in a week. animals should be handled regularly and fully famil- iarized with the methods of restraint to be used later. establish a laboratory animal health monitoring (HM) programme as an integrated part of any quality assur-ance system. Section 1 Animal Welfare Considerations J.S. females in a week. A. The exact procedure for rodent breeding for investigators is performed according to instructions in the individual animal use protocols. This handbook attempts to provide a basic guide to anaesthesia for research workers and animal technicians. Methods of Mating Livestock: The two method of mating livestock breeding is natural and artificial. Care and Use of Laboratory Animals on performance goals as opposed to engineering approaches is a theme that resonates throughout. The goal of that course was to train students to program new ideas in animal breeding. In fowl, they also secrete the seminal fluid. 1st Year ANIMAL HANDLING TECHNIQUES 2. Federal Regulations and The Guide for the Care and Use of Laboratory Animals require appropriate management and housing for breeding. Mouse stocks and breeding methods were as de-scribed by Bruce & Emmens (1948). Many of the techniques used are poorly understood and produce unpredictable results. The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities—a resource of proven value, now updated and expanded. Laboratory Animals, 2002), with the intention of harmonizing HM pro-grammes. But recent developments in molecular biology have given biotechnology ... basic tools of modern biotechnology (6). Generations: P1 x P2 F1 F2 Too much inbreeding, beyond S6, may be deleterious Year 1 Year 2 Year 3. Akodon molinae (Rodentia Cricetidae), a new laboratory animal: breeding, management and reproductive performance used by all persons responsible for laboratory animals and particularly by licensees and others now working under the authority of the Animals (Scientific Procedures) Act, 1986. Selection of males is less intense in this as a bull can be used for mating only 2-3 times, i.e. Laboratory Animals, 2002), with the intention of harmonizing HM pro-grammes. An example is the crossbreeding of Yorkshire and Duroc breeds of pigs. Random breeding methods are used to maintain outbred stock. It rotates and sprays semen during mating. Breeding Strategies for Maintaining Colonies of Laboratory Mice A Jackson Laboratory Resource Manual Th is manual describes breeding strategies and techniques for maintaining colonies of laboratory mice. Breeding cage cards should be filled out completely. The macroenvironment is the physical environment of the secondary enclosure (suc h as an animal holding room, a barn, etc.).
