Research improves breeding evaluations for Hereford cattle, suggesting better selection methods for livestock.

The aim is to enhance the assessment methods for the breeding qualities of Hereford cattle, focusing on productive and reproductive traits.
Analyzed breeding and genetic parameters from 2012 to 2024.
Studied three groups of animals across seven calvings.
Measured live weight, body condition score, milk productivity, pregnancy duration, inter-calving interval, and service period.
Inter-calving interval showed high variability (Cv = 7.79–12.98%).
Reducing open period to 90 days can increase offspring by 26.4%.
Milk production significantly influences breeding evaluations and heredity affects it up to 10%; recommended threshold for elite classification is 193.5 kg for first-calf heifers.

Dzhulamanov et al. (2025) studied this question.
