This guide to animal breeding in tropical countries explains what can and cannot be achieved. It starts by dealing with basic genetics and then deals with the various techniques used in animal breeding - selection, crossbreeding and inbreeding, and the effects that each of these can have on the animal populations. The author gives examples of each and points out their limitations when applied in the tropics. He also identifies systems of potential value, such as the use of multiple ovulation and embryo transfer. The book deals with specific considerations, such as the effect of climate on animals, the problems faced when dealing with tropical species, such as buffalo, and factors to take into consideration when dealing with individual traits.
