Abstract

This study advocates for the strategic repositioning of local animal genetic resources, re-evaluating them not merely as remnants of cultural heritage but as critical biological archives essential for ensuring future food security. The contemporary livestock sector is navigating a precarious transition as global production systems encounter an ecosystem based bottleneck induced by decades of intensive monoculture. By contrasting the physiological and genetic characteristics of high yield industrial breeds with the inherent resilience of local genotypes, the research highlights a fundamental trade-off between short-term productivity and long-term environmental adaptation. Research suggests that while industrial populations face potential metabolic weakness under escalating Temperature-Humidity Index (THI) thresholds, indigenous breeds maintain superior homeostatic capacity through specialized mechanisms such as Heat Shock Protein (HSP) synthesis and complex MHC polymorphisms. Furthermore, the emergence of Digital Sequence Information (DSI) and CRISPR based biotechnologies has transformed the conservation of these resources into a protean struggle for biosovereignty and intellectual property. In this context, repositioning indigenous breeds moving beyond the constraints of laboratory centric breeding paradigms is imperative. For regions with ancient livestock cultures, establishing a resistance line between the land and the animal is a matter of geopolitical vision and national defense. Ultimately, the synthesis of survival and yield determination modeling in climate scenarios up to 2050 confirms that the genetic adaptation shaped by long term evolutionary processes of local genotypes constitutes the most reliable biological insurance against next generation pathogens and resource scarcity in the 21st century.
