Final answer:
The main differences between indigenous and improved pig breeds lie in genetic diversity, with indigenous breeds having more, growth and production, with improved breeds growing faster and being more productive, and adaptability, where indigenous breeds fare better in varying conditions.
Step-by-step explanation:
Differences Between Indigenous and Improved Pig Breeds
When comparing indigenous pig breeds with improved pig breeds, several differences can be observed:
Genetic Diversity: Indigenous breeds typically exhibit a higher genetic diversity due to their adaptation to local environmental conditions over many generations, whereas improved breeds may have been selectively bred for specific traits, reducing their overall genetic variability.
Growth and Production: Improved breeds are often selected for rapid growth and higher production efficiency. They tend to reach market weight quicker and have a greater lean meat percentage than indigenous breeds, which usually grow slower and may be more suited for subsistence farming.
Adaptability: Indigenous pig breeds are generally more adaptable to harsh and variable local climates and may have a greater resistance to local diseases. In contrast, improved breeds often require specific and controlled farming conditions to realize their production potential.
While indigenous breeds may be more suitable for traditional and subsistence farming methods, improved breeds are often preferred in modern, intensive production systems for their growth performance and efficiency.
