The same after selective breeding. A cow's weight, of course, increases as the fetal calf inside her grows until it's time to give birth to push him out.
Cows weren't "made," they evolved and descended from ancient animals from the pre-Cambrian period. Domestic cattle themselves evolved and were selected by man (which would be artificially) from their wild ancestors being the Aurochs and Celtic Longhorns. From these ancestors, and through selective breeding, various breeds and types of cattle were formed and created, forming four main types of cattle: sporting, dairy, beef, and dual-purpose (both dairy and beef). The breed that is probably the closest-related to the Aurochs are the Spanish Fighting cattle.
Puberty in cattle is the same for humans: it is the time when a heifer or bull begins to become more receptive to the possibility of conceiving offspring, due to the fact their reproductive organs start reaching maturity and their secondary sexual characteristics begin to develop. Sexual maturity is when the reproductive organs reach maturity enough that a heifer is old enough to conceive or a bull is old enough to start breeding heifers and cows. Age of puberty in cattle is highly dependent on the breed and how selective for fertility a producer is for his/her cow-calf herd. Heifers in herds that have high fertility have been known to start puberty as early as 4 or 5 months of age. Other herds or breeds may not see heifers beginning puberty until they're between 9 to 12 months of age. Brahman and zebu cattle may have heifers beginning puberty as late as 15 to 20 months of age. The latter breeds often don't see heifers being bred to calve until they're around 24 or 25 months old. The former often have a rule of thumb with having heifers not to be bred until they're 15 months of age. However, some breeders of the more highly fertile herds may find that they have no issues with breeding heifers a few months younger. Of course this is all down to the producer's discretion and management goals.
The Jockey Club (Thoroughbred registry in US) registers about 37,000 foals every year with the majority from, of course, the Bluegrass state, Kentucky. Followed by Florida, California and New York.
Selective breeding helps to rule out weakness and disability in animals and helps make farming more lucrative for farmers by providing more robust animals for sale. Corn would only have ten kernels or less per ear withour selective breeding!
Selective Breeding of course!

The female two toed sloth is probably one of the most selevtive breeding animals. Her mate must do the can-can before she will breed with him. Of course, the most selevtive in biology it the venemous tentacular.
Selective breeding, the farmer will select what bulls to breed to what cows in order to increase milk production.
Although there are places where the horse is still used much the same as he did 100's of years ago, most modern horses are pets. Through selective breeding there are now many different breeds for many different uses. Whether cutting cattle or negotiating a cross country jump course, the horse will always have a place in the lives of humans.
I'm unaware of any animals which cannot be selectively bred. If offspring are produced through the mating of male and female of the species, you should be able to select for the most desirable traits in both parents. This assumes, of course, that the breeding stock are already in captivity.
yes of course
Of course you can, why wouldn't you?
Yea of course he is
yes !!!!!!!!!!! of course
ANGUS of course!!
Saliva and of course their mouths.
