Appropriate Genetic Approaches for Heat Tolerance and Maintaining Good Productivity in Tropical Poultry Production: A Review

SIMPLE SUMMARY: Tropical regions exhibit a wide range of climatic and environmental conditions. Therefore, to optimize the selection of genetic approaches to address heat stress affecting poultry productivity, this article compiles the different advantages and limitations of genetic methods for readers to have information to help them decide which method is suitable for their area and with genetic methods inevitably produces more sustainable results than other methods. ABSTRACT: Heat stress is a major environmental threat to poultry production systems, especially in tropical areas. The effects of heat stress have been discovered in several areas, including reduced growth rate, reduced egg production, low feed efficiency, impaired immunological responses, changes in intestinal microflora, metabolic changes, and deterioration of meat quality. Although several methods have been used to address the heat stress problem, it persists. The answer to this problem can be remedied sustainably if genetic improvement approaches are available. Therefore, the purpose of this review article was to present the application of different approaches to genetic improvement in poultry in the hope that users will find suitable solutions for their poultry population and be able to plan future poultry breeding programs.
