Overview

Randomized trial estimates genetic parameters for milk and reproduction traits in Carpatina goats, suggesting ways to improve local breeds.

Key Points

  • The study aimed to estimate genetic parameters for milk yield and reproductive traits in Carpatina goats.
  • Utilized data records from 1517 goats.
  • Applied an animal model for reproductive traits.
  • Used a random regression test-day animal model for daily milk yield.
  • Average age at first kidding was 498.54 days, with low heritability estimates (0.09).
  • Mean daily milk yield was 1.19 kg at 78 days, increasing to 1.21 kg at 140 days with heritability increasing toward the end of lactation.
  • Litter size and kidding interval also showed low heritability estimates (0.05 and 0.08 respectively).
