Bulling is a behaviour seen in cattle when one mounts another, usually when one or the other is a female in oestrus (on heat); "bulling" is commonly used as a term for a female in oestrus. Female cattle in oestrus may mount any adult cattle, especially a bull (fertile male) if one is present, but they will also mount ...
Since cow-cow mounting is an accurate sign that the time is right for taking the cow being mounted (“mountee”) to be bred, and that estrus is imminent in most mounting cows (“mounters”), selection for this behavior was probably coincidental.
Mounting other cows.
The act of mounting other cows may be a sign the cow is in heat or approaching heat. Although it's not a primary sign of heat, you should watch cows exhibiting this behavior closely for standing behavior.
Natural breeding and artificial insemination are the two primary processes involved in the cow's reproduction. In natural breeding, the fertile bull, capable of breeding with many cows for minimal production of calves, is used in the process.
Behavior As can be seen in Table 2, mounting other cows, restlessness and increased walking were observed very frequently at oestrus during pregnancy.
However, if an ovum is released after the female is already pregnant, there is a chance of a second pregnancy—albeit at a different stage of development. The mother cow evidently became pregnant in July, and again in September.
Berry and Cromie (2007) reported that older cows were more likely to give birth to a bull, whereas younger cows were more likely to give birth to a heifer.
No, cows and horses cannot mate with one another. Although they are both mammals, they are from different species and are unable to successfully breed with one another.
Usually a bull will mate with a cow once, but it's not uncommon if it's done several times, especially if she has garnered the attention of more than one.
Like humans, cows only produce milk as a result of being pregnant. Dairy cows must give birth to one calf per year in order to continue producing milk. Typically they are artificially inseminated within three months of giving birth.
How long is a cow pregnant? A cow is pregnant for around nine months (or 279 to 292 days).

Cows use sound (mooing) to communicate with each other and their environment. Cows are herd animals and have complex social structures. Mooing is one way that they interact and how they express their emotions.
Mounting behavior is commonly recognized as a sexual behavior that is performed by cattle to identify female cattle in estrus and possibly attract a bull for breeding.
Signs of heat
As the animal comes into heat, she is restless and may bawl and wander in search of a bull (traveling three or four times as much as she would normally do), sniffing other cattle. She interacts more with herdmates — licking them or fighting with them.
While bulls are known for aggression, female cows are just as likely to kill, especially right after they've birthed a calf. Maternal defensive aggression is the likely culprit.
What are the do's and don'ts of breeding a bull to his daughter, mother, granddaughter, or sister? Mating any of the above would result in a high level of inbreeding. Generally speaking, inbreeding of this nature should be avoided.
To achieve the ideal calving distribution, the guidelines for the length of mating are: maximum 60 days for bulls run with cows. minimum 45 days for bulls run with cows (if bulls are not run with the cows for long enough, the calving percentage is decreased).
that a mature bull can service 25 to 35 cows; however it has been shown that highly fertile bulls can service up to 50 cows. *Some heifers may have been included in this category. An annual reproductive examination is important to ensure that bulls are healthy and fertile.
Donkeys are kept in the company of horses to breed mules. Similarly, donkeys which live with cows are likely to mate with cows, if the donkeys don't have a female partner, says the expert.
Horses can breed with two different animals that are of different species as long as they are within the same Equidae family group. Horses can breed successfully with donkeys and zebras, although their offspring are usually sterile, unable to procreate themselves.
Hinny: The result of a horse stallion mating with a female donkey. Hinnies are less common than mules and there might be subtle differences in appearance. Size: Varies greatly depending on the stallion and mare.
Farmers typically use artificial insemination to get cows pregnant. This procedure consists of inserting one gloved hand and arm into the rectum to apply downward internal pressure, causing the cow's vulva to open. Once the vulva has opened, a long catheter is placed into the cow's body.
The occurrence of pregnant cattle at slaughter is unavoidable because of health, manage- ment, and economic reasons, or because farmers may be unaware of their pregnancy status.
Castration is the removal of the testicles from male animals. A bull that has been castrated is called a steer. There are various castration methods, and it is recommended that castrations be performed in calves at the youngest age possible (1), preferably within three months of age (2).
