“…According to Carson et al (2009) knowledge on breed distribution can indicate regions at risk from diseases that can wipe out populations of Animal Genetic Resources (AnGR). In Brazil, the smaller commercial breeds are at greater risk than the naturalized breeds which tend to have a wider distribution.…”

“…Unlike the British study (Carson et al, 2009), Brazil is a continental sized country ranging from the equator to the Tropic of Capricorn, englobing at least six different and distinct ecosystems. Most of the breeds have no formal breeding plans in place and studies have shown that breed success depends largely on environmental factors, especially in stressful environments.…”

“…According to Carson et al (2009), the investigation of breed distribution provides a valuable foundation for future research into genetic diversity within and between breeds, and serves as a baseline of information to enable population trends to be examined and a robust evidence-base for policy decisions on Farm Animal Genetic Resources (FAnGR). Most studies find high correlations between genetic diversity and geographic distance (Pariset et al, 2009;Kijas et al, 2012) but the lack of knowledge on distribution of breeds may hinder the establishment of effective breeding programs.…”

“…An example that has received increasing attention in recent years, particularly following the 2001 foot-and-mouth disease epidemic in the United Kingdom, is endemism (concentration of a breed population in a limited geographical area). Carson et al (2009) show that substantial numbers of British sheep breeds are highly concentrated in their distributions (in 10 out of 12 breeds studied, 95 percent of the population was located within a radius of 65 km of the mean geographical centre of the breed's distribution).…”

“…It is predicted that climate change may be accompanied by natural catastrophes like flood, earthquake, emergence of new disease, etc. There is risk of local rare breed being lost in localized disasters (Carson et al 2009). To secure against such disasters, it is necessary to conserve these breeds using ex situ method of conservation like cryo-conservation of genetic material in gene bank.…”

Environmental Stress and Amelioration in Livestock Production

The concept of adaptability revolves around fitness describing relative ability of an individual to survive and reproduce next generation to ensure continued survival of the population and is the result of natural selection over many generations. Current trend in genetic selection has severely eroded the genetic base ignoring the diversity of the production milieu, importance of adaptation, production of multiple products and social value of the livestock. The problem has been compounded with non-capturing of environmental costs though animal genetic resources (AnGR) on extensive and intensive scale are affected by direct impacts of climate change. Unplanned genetic introgression and crossbreeding has contributed to the greatest extent toward the loss of indigenous breeds. The genetic mechanism influencing fitness and adaptation is not well explored and adaptation traits are usually characterized by low heritability. Further, it may be difficult to combine the adaptation traits with high production potential as there seem to be different physiological and metabolic processes involved. Though decision regarding matching genotypes with environment or vice versa will be situation specific, the low and intermediate level of animal production in many parts of the world suggests that increased yields and efficiency will be more environmentally sustainable than extensive goals ensuring genetic diversity, environmental soundness, animal health and welfare, and social viability. Breeding for climate change adaptation or mitigation will not be necessarily different from existing
