Growing Heifer Checks Before First Breeding

A young heifer can be checked before her first breeding with a brucellosis test, a blood count, a mineral profile and a progesterone test. Together they help a vet look for a serious herd infection, check her general health and see whether she has started to cycle. Your vet decides which tests she needs.

Why check a heifer before first breeding?

A heifer is a young female that has not yet calved. She is about to join the milking herd, so this is a good moment to check her. If you bought her rather than raised her, her past may be unknown, which makes a starting check even more useful. An infection she carries can spread to other animals. A heifer that is thin, anaemic or short of minerals may be slow to come on heat or may struggle to hold a pregnancy.

Your vet will also look at her size, growth and general condition by examining her. The vet decides when she is ready for breeding. Lab tests add information, and a registered veterinarian reads them together with her feed, health history and the way she looks.

What does the brucellosis test do?

Brucellosis is a bacterial infection that mainly affects breeding. It may cause abortion and retained afterbirth in cattle. It can also pass to people, through raw milk and through birth fluids or aborted material. Wash your hands, wear gloves when handling such material, and speak to a doctor if you feel unwell.

The Brucellosis Test (RBPT / ELISA) looks for antibodies in the blood. RBPT is a quick screening test and ELISA is a laboratory method; the lab confirms which is used when you book. A negative result does not always rule infection out, for example when the infection is new. If the heifer has been vaccinated against brucellosis, tell your vet, because vaccination can affect some antibody tests.

Why check minerals?

Calcium, phosphorus and magnesium help bones, muscles, nerves and growth. A heifer fed on poor or one-sided fodder may fall short of them. The Mineral Profile (Calcium, Phosphorus & Magnesium) measures these three in the blood. Low phosphorus, for example, may go with poor growth and late heats.

The body holds blood calcium steady, so a normal calcium value does not always mean her stores are good. Your vet reads the profile with her feed and growth. The Mineral & Trace Element Pack goes further and looks at trace elements too; the exact list is confirmed when you book.

What does a blood count add?

A Complete Blood Count (CBC) counts red cells, white cells and platelets. Fewer red cells, called anaemia, may go with worms, ticks or poor feed. Changes in the white cells may indicate infection or inflammation. It is a quick way to see whether a heifer is healthy enough to be bred, and a baseline to compare with later.

What does the progesterone test show?

Progesterone is a hormone made by a structure that forms on the ovary after an egg is released. A higher level in the blood may indicate that her ovaries are active and she has ovulated, or that she is pregnant. A low level is expected around the time of heat.

The Progesterone, Serum gives a snapshot of one moment, so your vet may repeat it, or combine it with heat signs and an examination. It is most useful for a heifer that is old enough to breed but has never been seen in heat. Note any dates when you see signs of heat, such as restlessness or mounting other animals, and tell your vet. The Repeat Breeder Fertility Pack groups checks for animals that fail to conceive; it is mainly for cows, so ask your vet whether it suits a heifer.
