A heifer cow.
A heifer is a young cow, usually one that has not yet given birth to a calf. These cows are an important part of the herd dynamic as they represent substitutes for older cows. In the dairy industry, they are desired as they will eventually produce milk. In the meat industry, the gender of young cattle is not as important as they are usually destined for slaughter in both cases, although some heifers may be retained to produce more calves.
Unneutered adult male cattle are called bulls.
Cattle in general are widespread throughout the world and a number of complicated terms are used to refer to cows at various life stages. An ox, for example, is a young bull, and he can grow up to be a bull or ox, or he can be castrated to become a bull. Adult females are often referred to as cows, and ranchers may have additional specific terms to define the animals they work with. These terms can get a bit confusing outside of the industry, and some livestock terminology requires very graphic explanation.
Dairy producers raise heifers as often as possible to see if they produce enough milk.
The exact usage of the term “heifer” varies. In some regions, the term is used to describe a cow that has not yet given birth, until the time of calving. One in the last weeks of pregnancy is sometimes called a nascent heifer. In other regions, a cow may be called by this term even during her first lactation, after which she is considered a fully adult cow. In some areas, the term “first calf” is used to describe a cow that has produced a single calf.
Heifers are an important part of herd dynamics as they represent substitutes for older cows.
The management of young cattle varies, depending on the final destination of the animals. Cows are generally sexed early in the livestock industry, with most calves being castrated to make them easier to handle. Young cows have potential economic value as they can produce both calves and milk. A dairy farmer usually raises heifers as quickly as possible to determine whether or not they produce adequate milk.
After calving, the cow is no longer a heifer.
In regions of the world with programs that sponsor young farmers, such as 4-H or FFA, many people enjoy raising heifers as a project. A young cow is generally kinder and easier to handle than an ox. When it reaches full size, it can be auctioned off at a cattle auction, which can be an interesting learning experience, or the student can create it to expand the scope of the project.
