Abstract
<jats:p>Associations between protein feeding and reproductive efficiency in the dairy cow are reviewed. Examination of published data indicated that reproductive responses assessed as days open, services per conception or conception rate following changes in protein feeding tend to be inconsistent. Discrepancies can arise due to between-study variations in experimental design, statistical analysis, sample population size, uterine health, cow age, parity, reproductive management or nutrient intake. Detri-mental effects on reproductive efficiency following periods of excessive protein feeding are often attributed to increases in tissue urea and ammonia oncentratio...
