What does this research mean for the field?

Body weight in female Jiangyue donkeys can be accurately estimated using morphometric traits, particularly chest circumference, and their population-level age-weight relationship is best described by the Brody model. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the predictive accuracy of 11 morphometric body measurements for estimating live body weight and to model population-level growth dynamics in female Jiangyue donkeys.

Implication

Cross-sectional study demonstrates strong predictive value of morphometric traits for body weight in female Jiangyue donkeys, suggesting practical tools for herd growth monitoring.

Key Points

To evaluate the predictive accuracy of 11 morphometric body measurements for estimating live body weight and to model population-level growth dynamics in female Jiangyue donkeys.
Recorded body weight and 11 morphometric traits in 484 female Jiangyue donkeys, using stepwise regression to build weight prediction equations.
Fitted four nonlinear growth functions (Logistic, Gompertz, Brody, and von Bertalanffy) to cross-sectional age and body weight data from 241 females.
Body weight positively correlated with all 11 morphometric traits (p < 0.01), with chest circumference exhibiting the strongest correlation.
Stepwise regression equations accounted for 91.8% of weight variation in growing donkeys and 84.4% in adult donkeys (both p < 0.01).
The Brody model provided the best fit for growth trajectories (R² = 0.99960), projecting an asymptotic mature body weight of 191.049 kg.
