Color Inheritance In Farm Animals

For animal breeders coat color genetics is one of the fundamental elements of breeding, along with health and conformation. Breeders need to know about coat color for showing purposes and where the fibre is used in industry, for example sheep and alpaca wool.Breeding for coat color is complicated because many dominant and recessive traits interact to produce the base coat color. Alleles for these occur in pairs, so that the phenotype, or visual appearance, does not always reflect the underlying genotype.Practical Color Genetics for Livestock Breeders is a guide for breeders on the biology behind coat color in large animals directing breeders on how to implement breeding strategies to achieve desired results.

It is very important to understand the recent advances and basic concepts of veterinary genetics to explore the possibilities for control of diseases in animals. They are also significant for enhancing animal production and reproduction. Our book Trends and Advances in Veterinary Genetics provides a concise introduction and details to the aspects of genetics relevant to animal science and production. This is the first edition of the book so it covers the introductory level of topics which are ideal for veterinary students, classroom use, and practitioners who require more guidance with genetics. The book coverage includes the following main sections: Biotechnology and Reproductive Genetics, Advances in Embryonic Genetics, Conservation and Basic Genetics, and Veterinary Genetics and Future. Each book section comprises two chapters from renowned experts from the area and gives readers a unique opportunity to explore the topic.

Different tests have been developed for evaluating the temperament of cattle, pigs, and sheep and some studies appear to have conflicting results. This may be due to confusion between the basic emotional systems of fear and separation distress (panic). Methods used for temperament tests can alter results such as how tightly an animal is restrained in a squeeze chute during temperament evaluation. Animals with a more reactive (fearful) temperament will exhibit greater agitated behavioral reactions when suddenly confronted with novel objects. Animals can be habituated to new things but learning is very specific. Habituation to one type of strange object may not transfer to other types of objects. Animals with smaller-diameter leg bones and slender bodies may be more reactive (fearful). Facial hair whorl position is related to a vigilant temperament and it may be more evident in populations with more diverse genetic backgrounds.
