Animal genetic diversity is essential for both rural development and food security. It enables farmers to make decisions about their livestock or create new breeds in response to changing environmental factors like climate change, disease threats from emerging or resurgent diseases, updated information about the nutritional needs of people, and shifting market conditions or societal demands. These are all mostly unpredictable. The need for food will likely increase in the future, which is predictable. The implications will be most noticeable in emerging nations, where demand is predicted to rise at a rate that is faster than production growth and where climate change is anticipated to have the biggest effects.

Climate change affects and is affected by the production of livestock. The repercussions of climate change are likely to include an increased chance that geographically confined rare breed populations may be severely impacted by disruptions in addition to the physiological impacts of higher temperatures on individual animals. Ecosystem changes that modify the distribution of animal diseases or have an impact on the supply of feed can have indirect effects. In order to account for higher temperatures, worse diets, and a larger challenge from disease, breeding goals may need to be altered. Breeds and species that are well suited to these circumstances could grow increasingly popular. The use of breeds and species may change as a result of climate change mitigation methods, leading to a shift toward monogastrics and breeds that are proficient at converting grain into meat, milk, and eggs. This could result in the undervaluation of native breeds' capacity for adaptation in developing nations.

The traditional analysis of variance is a good tool provided that the interaction component of variance is corrected for significant differences between environments in the extent of genetic effects. Methods of measuring genetic-environmental interaction were examined In order to account for the potential for negative genetic correlation, it is recognized that the variance component for the average effects of genetic groups is comparable to the average covariance of the same genetic group across different contexts.

Every time animals are bred with a specific goal in mind, such as for a specific function, environment, or market, precision animal breeding ought to be applied. Therefore, it ought to apply whenever animals are bred for any of the four aforementioned purposes. This is appropriate given that the methods employed are mostly universal. It show how they have improved in precision over time most importantly, show how generic technologies are opening up opportunities to significantly increase precision and demonstrate what needs to be done to take advantage of these opportunities. Animal breeding is frequently regulated or affected by law, as well as by local, national and international organizations.

Because it is impossible to discuss precision animal breeding without taking into account either of these elements, as well as animal population levels and their economic and cultural relevance, it has been vital to situate the research within a broader context. On the other hand, we had to restrict the number of species we could investigate, so we'll focus on terrestrial vertebrates.
