Most Angus cows are already past this age--they are mature female bovines that have already had a calf and are past 2 years of age.
Yes, if he's already reached puberty.
The weight of a Black Angus heifer can vary significantly depending on age and genetics, but typically, they weigh between 600 to 1,200 pounds (272 to 544 kg) by the time they reach maturity. A heifer that is around 6 to 12 months old might weigh closer to the lower end of this range, while older heifers approaching breeding age will be on the higher end. Proper nutrition and management can also influence their weight.
When she shows her first signs of heat, you have to AI her 12 hours later. The process of AI-ing only takes a couple minutes, or even shorter if you're really good at it. As for the natural process, the act of copulation between a bull and a cow only takes a few seconds.
A cow would be liable to breed for until she's over 20 years of age. On average, a cow is expected to have a breeding span of 10 to 15 years. However, the actual span depends on the breed; Brahman and Brahman-type cows tend to live longer than British or Continental cattle, and they tend to breed for longer than dairy cows.
A Steller's Sea Cow typically gave birth to a single calf at a time. The gestation period for these marine mammals was around 11 to 12 months, and mothers would nurse their young for several months after birth. This reproductive strategy is similar to that of other large marine mammals. Unfortunately, Steller's Sea Cow went extinct in the 18th century, primarily due to human hunting.
The average weaning time would be 8-10 months. The mother will naturally wean the calf around 12 months.
most bulls are fertile by 12 months and can service anytime after that
Once every 11 to 12 months, accounting for the period of rest a cow gets after being bred (which will last from 2 to 3 months), and the gestation period for that cow after she has conceived.
She's already the right age to be pregnant, since a cow is a mature female that has had one or two calves already. If she's open and has been open at least 45 to 60 days after having her last calf and is showing signs of normal estrus, she can be bred to be pregnant again.
Negative three to four months, assuming the cow gets bred two months after calving and the calf is weaned at six months of age. Seriously, a cow is already bred and into her second trimester when her calf is weaned. Cows are not like human females where they can only get pregnant again at least a year or 8 to 12 months post-partum.
For one cow, it's usually 11 to 12 months in between each calving. For a cow-calf operation with defined breeding and calving seasons, it's always 12 months in between the start of one season to the start of the next.
Yes, if he's already reached puberty.
