What does this research mean for the field?

Early-life body and testicular measurements strongly correlate with each other and are significantly influenced by breed, birth type, and lamb age, making them reliable indicators for selecting breeding male sheep. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the variation in body weight, morphometric traits, and testicular measurements in young male lambs across different breeds, birth types, dam ages, and lamb ages.

Key Points

To evaluate the variation in body weight, morphometric traits, and testicular measurements in young male lambs across different breeds, birth types, dam ages, and lamb ages.
Tracked 36 male lambs (18 Awassi and 18 Cukurova Meat Sheep) raised in the Cukurova region monthly from 1 to 4 months of age.
Evaluated body weight, anatomical body dimensions, and testicular parameters using a linear mixed-effects model accounting for breed, birth type, dam age, and lamb age.
Cukurova Meat Sheep lambs displayed significantly higher values for most morphometric traits and testicular measurements compared to Awassi lambs.
Single-born lambs demonstrated greater body and testicular dimensions than twin-born lambs, while lamb age had a strong positive effect and dam age exerted minimal influence.
Body weight, morphometric traits, and testicular measurements correlated positively, with scrotal circumference and testicular volume demonstrating an exceptionally strong association.
