Randomized trial evaluates genetic effects on growth traits in Deccani sheep, suggesting maternal influence improves outcomes.

The study aims to estimate genetic contributions to growth rate and Kleiber's ratio traits in Deccani sheep.
Utilized data from 2590 lambs between 2011 and 2020 at ICAR-Network Project in Maharashtra, India.
Assessed growth traits including average daily gain and Kleiber's ratios across different age groups.
Employed Bayesian inference to estimate genetic parameters using animal models and BLUPF90 programs.
Direct heritability estimates for growth traits ranged from 0.05 to 0.12, indicating low additive genetic variation.
Maternal genetic effects contributed up to 9% of the total phenotypic variance in growth traits.
Negative genetic correlation between direct and maternal effects reflects an antagonistic relationship.

Kandalkar et al. (2026) studied this question.
