Heifer – a cow that has not borne a calf, or has borne only one calf. In North America, a typical farm has about 100 milk cows and as many young female stock called heifers. The heifers are raised as replacement cows.
Frontal precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature. Along the fronts, the warm air rises above the denser cold air. The mid-latitude regions experiencing the convergence of warm tropical and cold polar air masses are important areas receiving frontal precipitation.
