What is a severe condition due to excess production of estrogen in ferrets?
The female ferret is an induced ovulator, meaning she must mate to terminate estrus. If she is not bred, she will remain in estrus which in time will result in excess estrogen in her body leading to a disorder know as estrogen-induced anemia, which can lead to leukemia and finally death.
What is the role of estrogen in cattle reproduction?
In breeding cows and heifers, estrogen is basically responsible for two things: 1) Bringing a female into heat or estrus so that she can be bred, since when a cow is showing signs of estrus this means she is ready to conceive or mate with a bull so that she can bear a calf. A cow nor heifer can become pregnant at any other time in their estrous cycle. Estrogen peaks at the time of estrus, which will change the behaviour of a cow or heifer from a seemingly placid, friendly animal to a madly rutting female that is desperately looking for a mate. 2) Encourage labour or parturition. Estrogen spikes when a cow is going into labour and ready to deliver a calf, and this estrogen is one of several hormones on the hormonal pathway to parturition (birth or calving) that is first initiated by the stress levels of the fetus.Basically estrogen is one of many female hormones that is very important in cattle reproduction in both breeding and calving. Estrogen cannot function alone, however, without the help from other hormones in the female's system, including progesterone, luteinizing hormone, and gonadotropin-releasing hormone. Estrogen is also used by producers as a hormone injection to synchronize the estrus patterns of several cows and heifers in order for them to come into heat at the same time, or close to, so they can be artificially inseminated. Estrogen or its similar form estradiol is also used to encourage abortion in cattle, especially in heifers that are too young to be in calf.

Why does your dog smell foul in between menstrual cycles?
Female dogs (bitches) don't have menstrual cycles in the same way that women do. Bitches go through estrus, or go into heat, three times a year. It is during these times that they are receptive to mating and can become pregnant. The odor of female dogs in heat is designed to attract males and increase the chances of mating. You can reduce the smell of your bitch's genital area by purchasing "bitch's britches" and pads for her to wear during estrus. These are available commercially and also reduce staining of furniture, carpeting, etc.
How does estrogen affect the behavior of a cow during mating?
Estrogen is the hormone that induces estrus, or the heat period where a cow is susceptible or ready to be bred by a bull. The cow acts more vigorously during her heat period than when she's not in heat, mooing a lot, pacing the fence-line, inducing other females to mount her, or encouraging the bull to follow her and attempt to mount her. She tends to be more focused on finding a mate than on eating or sitting down and relaxing, and may go off feed temporarily during estrus.
