How long do you leave a bull in with cows?
Subject: Re: How long do you leave your bulls in.
Same here 60/75 give or take 2-3 days.
60 days exposure gives us close to 70 days of the cows calving and that is a huge difference between the calf that is 70 days older than the youngest @ weaning.
80%+ calve in 30 days so those last ones are killing your weights..
When can a heifer get pregnant?
A: Breeding should occur when the heifer reaches puberty. Puberty is a function of breed, age, and weight. Most heifers will reach puberty and be bred by 12 to 14 months of age and will be between 55% and 65% of their mature weight when they first begin to exhibit estrous cycles.
How many calves can a cow have in one pregnancy?

Will a bull mate with the same cow twice?
Yes…the bull will breed the same cow over again during the same cycle.
Are milking cows always pregnant?
“Cows in dairy production are forced to become pregnant nearly every year of their lives.” Cows, like all mammals, begin to make milk when they give birth. Milk production rises after calving, then naturally declines unless the cow has another calf. Cows are bred to become pregnant to complete the cycle.
How far away can a bull smell a cow in heat?
six milesThose crimson flags that matadors wave in the rodeo ring only catch a bull’s attention because of their fluttering. Cows have an acute sense of smell and can detect odors up to six miles away, which is also helpful in detecting imminent danger.
How long do you wait to breed a cow after calving?
30 daysIt takes at least 30 days after calving for a cow’s reproductive tract to return to normal. Therefore, some cows can be bred starting 45-60 days after calving.
How often does a beef cow cycle?
every 21 daysAfter puberty, a heifer continues to have regular estrous cycles every 21 days (the normal range is every 18 to 24 days). The estrous cycle in cattle is complex and regulated by several hormones and organs (see Figure 1).
Will a bull mount a pregnant cow?
Seven of nine pregnant cows at oestrus stood willingly to be mounted by a bull. … True oestrus begins when the female assumes the mating stance so that the male may mount and copulate. It does not normally occur during pregnancy in farm animals, although it is known to occur sporadically in cattle.
Do cows have periods?
Cows do not have periods but they do have heat cycles. … The term period is a human reference to a female’s monthly menstruation, the bleeding that occurs if a woman does not become pregnant during their monthly reproductive cycle. Cows do not menstruate; therefore they do not have a period.
What causes a cow not to breed?
The most common cause of infertility in beef herds is poor cow nutrition. Over conditioning can also be detrimental, especially in heifers, but is far less common a problem. Body condition before calving, after calving, and at breeding can all contribute to infertility.
How do you tell if a bull is breeding?
Look for raised hair, mud or bare patches over the female’s hindquarters. Also an indication of mating and estrus activity, it is another useful way to see if a cow has been serviced or not. These characteristics should be used to note breeding activity, but only if there is a breeding bull with the females.
How many times a cow can give birth?
As one local dairyman puts it, cows get their maternity leave for a couple months before they give birth. It usually works out that cows are giving birth every 12-14 months. With the life span of U.S. dairy cows averaging 4-6 years, most cows have 2-4 calves in a lifetime.
