Carcass yield traits of kids from a complete diallel of Boer, Kiko, and Spanish meat goat breeds semi-intensively managed on humid subtropical pasture

摘要: Bucklings (n = 275) from a complete diallel of Boer, Kiko, and Spanish meat goats were slaughtered at 7 mo age (4 postweaning) to evaluate genetic effects on carcass yield. Breed sire did not affect (P > 0.05) live, carcass, primal weights. Conversely, breed dam was consistently significant source variation for weight traits. Kiko dams produced kids with heavier Boer or Kiko. Subjective conformation scores muscularity affected by breeds dam. Direct negative weight, dressing percent, shoulder positive proportional leg weight. differ 0.10) 0 any trait tested. Heterosis levels similar among pairings. substantial ≤ weights (5 9%) but boneless yield, proportions (<2%). Significant observed goat yield Dam more influential than breed. germplasm superior when semi-intensively managed humid, subtropical pasture. Results emphasize the importance comparative evaluations provide industry reliable information genotypes.
