Randomized trial examines body and carcass traits in pigs, indicating significant effects of gender on growth and morphology.

This study aims to investigate the impact of sexual dimorphism on economic traits in pigs.
80 grower pigs, averaging 4 weeks old, were randomly assigned into 2 groups with 4 replicates.
Data collected from 6 to 18 weeks, measuring body weight gain and feed intake.
Key morphometric and carcass traits such as body length, ham length, and weights of various organs were assessed.
Males displayed significantly higher body weight gain (19.75 kg vs 16.39 kg, p<0.05).
Ham length was significantly greater in males at multiple ages (e.g., 26.20 cm vs 22.28 cm at 16 weeks, p<0.05).
Males had a better feed conversion ratio (6.70 vs 7.78, p<0.05), indicating more efficient growth.

Sorhue et al. (2026) studied this question.
