Breeding strategies for sustainable livestock production in developing countries are discussed with reference to breeding objectives in more uniform environments of temperate regions and to those in stressful and highly variable environments of the tropics. The relative importance of breeding objectives to be based not on single performance traits but also on fitness traits is discussed in relation to production efficiency. With particular reference to breeding strategies for dairy production the following aspects are referred to: assessment of scope for performance improvement; the rôle of local breeds in stressful environments; the need for potential assessment and options for breed improvement; the use of exotic breeds; and the need for comparative field performance test as part of improvement schemes.
