Pregnancy Of A Cow

The Pregnancy of a Cow

The pregnancy of a cow is an eventful and miraculous experience, from fertilization to the birth of their calf. A cow gestation or ‘term’ lasts approximately 285 days, which works out to be around 9.5 months. During this time, a lot happens inside the female cow’s body, and for those of us lucky enough to witness the birth of a calf, this is a truly incredible thing to behold.


When a female cow breeds with a male cow, this is known as ‘mating’. After successful mating, the female cow will usually become pregnant within a three-week window. Fertilization in mammals and cows in particular, is achieved when the male cow’s sperm combines with the female cow’s egg.

Stages of Development

Throughout the cow’s pregnancy, the young calf progresses in stages, with the initial embryonic development to birth.

  • First Trimester: During the first three months of pregnancy, the unborn calf will undergo important developments, such as organ and limb formation.

  • Second Trimester: During this 3-month period, you should notice the young calf’s movement, as well as gradually increasing in size.
  • Third Trimester: In the third and final trimester, the calf’s growth will increase even more, though there will be little movement.

Calf Delivery

The delivery of a calf is an amazing process, and is usually preceded by signs of labor such as:

  • Uterine contractions
  • Maternal restlessness
  • Transmission of labor noises
  • The discovery of a watery or mucous discharge from the genital canal.

The delivery itself is usually a peaceful process, lasting anywhere between a few minutes to an hour. The cow will then be on the cusp of giving birth and the calf should be birthed quite easily.

Calf Care

As the calf matures and their mother feed, the nutrition of their mothers’ milk will help them to grow. As such, it is important to keep a watchful eye on the calf and their mother’s health and nutrition to ensure they both stay happy and healthy.

It is worth noting that pregnancy can have a major effect on the cow, so be sure to check up on them regularly, and give them plenty of Tender Loving Care!
