Objectives
Upon completion of this course, the students will be able to understand the basic principles and fundamentals of animal breeding and the application of animal breeding techniques to improve the breeds of different species.
Syllabus of Principles and Practices of Animal Breeding in Bsc. Agriculture
Animal breeding is important, and its scope is in livestock improvement. Animal genetic resources and sustainable development of indigenous breeds. Rare breeds of different species of animals and their characteristics and economic values, the reason for being endangered, strategies and methods for conservation of AnGR, Variation and causes of variation, important of heredity and environment. Gene action (additive and non-additive). Concept of heritability and repeatability. Selection, selection response, selection limit, selection differential, methods and basis of selection, mating system, inbreeding, and outbreeding. Concept of genetic resistance to disease and parasites. Traits of the economic importance of different livestock species. Biotechnology in animal breeding, Nuclear transplantation, transgenic animal production, and its significance in genetic improvement of livestock.
Practical: Estimation of heritability and repeatability, means, breeding values and components of variances, calculation of inbreeding relation and coefficient, selection response, selection differential, genetic gain, probable breeding value, most probable producing ability, selection intensity, and selection index.
