Gut Microbiota Composition and Diversity in Different Commercial Swine Breeds in Early and Finishing Growth Stages.

ABSTRACT: The gut microbiota affects the metabolism, health and growth rate of pigs. Understanding the characteristics of gut microbiota of different pig breeds at each growth stage will enable the design of individualized feeding strategies. The present study aimed to compare the growth curves and development patterns of pigs of three different breeds (Duroc, Landrace and Yorkshire) using the mathematical models Gompertz, Logistic, Von Bertalanffy and Richards. For Duroc pigs, the Gompertz model showed the highest prediction accuracy (R² = 0.9974). In contrast, the best models for Landrace and Yorkshire pigs were Richards (R² = 0.9986) and Von Bertalanffy (R² = 0.9977), respectively. Path analysis showed that body length (path coefficient  =  0.507) and chest circum
