Abstract

In this paper we will focus on the results pertaining to the adult breeding herd from breeding season 1986 to calving season 1987. Unless otherwise stated, we will be referring to the randomly selected herds only. We will describe: how beef breeding herds are currently fed, housed, and otherwise managed; what happens to cows between breeding and the birth of a live calf; and what factors influence pregnancy and culling. Most of our work will focus on herd level information, since beef cows in Ontario and elsewhee are managed as herds rather than as individuals.
