Pregnancy In Ruminants
This topic provides information about Pregnancy In Ruminants.
What is pregnancy
- When the male mates with the female he deposits sperm in the vagina.
- The sperm joins with the egg and forms the embryo which becomes attached to the wall of the womb.
- The embryo grows within a bag of fluid (water bag) and is attached to the wall of the womb by a navel cord.
Signs of pregnancy
- Heat stops when pregnancy begins.
- The animal becomes quieter and the belly grows bigger.
- In milk animals the production of milk will gradually drop.
Length of pregnancy
- If male and female animals have been allowed to run together in a large herd it will be difficult to determine the expected time for birth (parturition).
- If however you do know when a female was mated or given artificial insemination you can determine when she will give birth.
- The length of pregnancy differs in different animals.
|Animal||Length of pregnancy|
There can be a few days difference either way depending on the type, climate, feed and other factors.
Management of the pregnant animal
- You must remember that a pregnant animal will need more feed and will benefit from the addition of some grain to the feed towards the end of pregnancy.
- All pregnant animals should be kept close to home towards the end of the pregnancy and some form of shelter should be provided.
- They should be watched twice a day for signs that parturition is close.
- In particular cattle and buffalo need a clean, well ventilated place, preferably with a sand or grit floor on which suitable bedding is placed.
- Do not keep a pregnant animal constantly tied up or with little room to exercise in. Allow her some freedom in a field or yard each day.
