ResuméHerd reproductive performance assessment integrates multiple metrics to evaluate the efficiency of breeding programs and overall population fertility. Formalized in the 1990s-2000s by dairy veterinarians and herd health specialists, the method combines individual animal records (conception rates, calving intervals) with population-level indicators (age structure, open days, pregnancy rate) to identify reproductive constraints. Assessment is fundamental to dairy profitability and sustainability.Milk yield recording is a systematic method for measuring and documenting the volume of milk produced by individual dairy animals across lactation cycles. Formalized in the early 20th century by dairy scientists including W. L. Gaines, the practice forms the backbone of modern dairy herd management and genetic improvement programs. It enables objective assessment of production performance and identification of high-producing animals for breeding.
