Abstract

Accurate and early identification of the likelihood of conception (LC) in cows is imperative for a profitable dairy farm. This study aims to use the milk mid-infrared (MIR) spectra in different intervals before the first insemination and partial least squares discriminant analysis (PLS-DA) to predict LC. The results show that the MIR data within 30 to 50 d after calving and close to insemination had a better prediction in LC (accuracy = 73.9 and 72.3%) than 0 to 30 d. And specificity (74.4 to 84.9%) was higher than sensitivity (67.8 to 73.1%). Once the expected date of insemination is given, the model can predict LC before the actual insemination, and intervene in advance for cows predicted poor LC such as delayed insemination and treatment can be initiated. The predicted LC also provide a novel and convenient way to accumulate extra reproductive phenotypes for genetic evaluation.
