Wanyama wafugwao na wanyama pori huwa wanapata joto kila baada ya muda fulani,mfano ngombe kila baada ya siku 21, na wakati huo wanweza kuonyesha dalili ambazo madakitari wamifugo/wafigaji huzitumia kuwapandishakwa dume au kupandisha kwa chupa.Not in the same way as in humans, no. Since some people here are obviously confused about what oestrus and menstruation actually are, I will explain.
Oestrus, commonly called being 'in season' or 'in heat', is the only time an animal can become pregnant - it is when the womb lining is thickened in preparation for pregnancy, and the ovaries have either released eggs or are about to release them with the stimulus of mating. In the majority of species, oestrus is the only time the animal feels sexual desire, since it is the only time pregnancy can occur and it would be pointless to mate at any other time. We humans are rare in that we are unaware ourselves of being in oestrus, though it happens once a month - we must work out where we are in our cycle or use ovulation strips to tell us when the best time to try for a baby is.
In humans, if a woman does not become pregnant during oestrus, the womb lining and unfertilised egg are discarded - this is menstruation, or 'having a period'. This does not happen in animals - they reabsorb the womb lining into their bodies instead of shedding it. When some animals, such as dogs, are in oestrus, they produce a bloody discharge, which may lead some people to think the animal is having a period. This is not the case - the animal is ready to conceive, not getting rid of its womb lining after failing to conceive.
[h=3]Source(s):Yes all animals have periods. It is called the HEAT PERIOD when the females accept the males for mating. In human it is called menstrual cycle as it is a monthly phenomenon. In other animals (specially mammals) it is called estrous cycle or oestrous cycle with different time period cycle. These cycles are hormone regulated.
Now for your curiosity, Animals (including humans) that have menstrual cycles shed the endometrium through menstruation - so you see blood; but other animals (like cattles) that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle - so often you don't see blood[/h]I used to be a zookeeper and have studied animals all my life.
