The liveweight performance and carcase characteristics of Brahman x Hereford, Africander x Hereford and Africander x Shorthorn F, crossbred spayed heifers were compared with those of local Shorthorn spayed heifers on native pasture at Katherine, N.T., between 1962 and 1965. The breed groups were divided for planes of winter nutrition, viz., with and without 2 lb a day of peanut meal from early June until the start of the wet season. Without supplement, the average weight gains of B x H, A x H, A x S, and Shorthorn cattle between June 1962 and May 1965 were 0.49, 0.37, 0.36, and 0.23 lb a day respectively. With supplement, cattle reached slaughter weight a year earlier ; the average weight gains of B x H, A x H, and Shorthorn cattle between June 1962 and May 1964 were 0.61, 0.63, and 0.50 lb a day respectively. (There was no A x S supplemented group). Without supplement, the dressing percentage and estimated proportion of fat of B x H cattle was higher and the estimated proportion of muscle and bone lower than those of other breeds. With supplement, there were no significant differences in dressing percentage or carcase composition between breeds. Measurements made of thermoregulatory attributes indicated that the local Shorthorn cattle, through body temperature control, showed adaptation to heat stress.

Small ruminants are the critical source of livelihood for rural people to the development of sustainable and environmentally sound production systems. They provided a source of meat, milk, skin, and fiber. The several contributions of small ruminants to the economy of millions of rural people are however being challenged by extreme heat stress difficulties. Heat stress is one of the most detrimental factors contributing to reduced growth, production, reproduction performance, milk quantity and quality, as well as natural immunity, making animals more vulnerable to diseases and even death. However, small ruminants have successfully adapted to this extreme environment and possess some unique adaptive traits due to behavioral, morphological, physiological, and largely genetic bases. This review paper, therefore, aims to provide an integrative explanation of small ruminant adaptation to heat stress and address some responsible candidate genes in adapting to thermal-stressed environments.
