Effects of summer pastures and winter feeding strategies on reproductive performance of beef cows

The reproductive performance of beef cows is a major factor affecting the profitability of beef production. Poor reproductive performance of beef cows can be associated with feeding management. As a result, continual assessment of management systems to ensure efficient use of available feed resources while optimizing reproductive performance is essential. The objective of this study was to determine the impact of summer pasture composition (i.e., grass with and without alfalfa) and winter-feeding strategy (i.e., drylot vs. extended grazing) on the reproductive performance of beef cows.
