Average weight is around 1600 lbs.
A newborn Holstein may weigh around 60 to 70 lbs. However, it's not uncommon for cows to give birth to calves 80 to 90 lbs.
Holsteins prefer a temperature range of 50 to 55 degrees F.
It depends in the breed! If you are talking about dairy cows the average Holstein Cow weights 1,300lbs give or take a couple hundred pounds. But that is for a mature cow. Dairy cows usually have their first calf at about 2 years old and not considered mature until they are about 5 or 6 years old!!! Cows only start producing milk when they have their first calf. Holsteins are the most common dairy cows in the world and the biggest and largest of the dairy cows. Jerseys are much smaller for example!
Dutch Belted cows were originally bred in Holland so they do fine with a northern European type climate. However being an antique breed, they are very sturdy and adapt much better to hot climates than say your typical Holstein cow. They can live pretty much wherever dairy cows in general live. They are disease resistant, have pleasant personalities, easy calving and sweet milk across a range of climates. == ==
A Holstein cow will average at around 1600 lbs. Bulls average around 2300 lbs.
A holstein heifer typically must be about 60% of the cow herd's average mature weight; so, if the average weight of all dairy cows in the herd is 1400 lbs, then she has to be around 840 lbs or more to conceive and be pregnant. But by the time she is fully mature body weight doesn't matter much; it is the fact that if she is bred and has had the calf that she can officially be a milking cow.
No they are much smaller
No. Cows are female, they're mature female bovines that have had a calf. Beef cows are genetically selected to produce more beefy frames than dairy cows are, and thus only produce enough milk for their calves. Beef cows are typically not selected for increased milk quantity like other dairy breeds are (including Holstein, Jersey and Brown Swiss), and thus, unlike dairy cows, do not produce so much milk that their one calf can't drink it all at one nursing.
Desi cows is a general Indian term referring to all cows that are used for milk and draft. Jersey is just a specific breed of cow that is also found in India along with other breeds that are indigenous to India, like the Nellore, for instance.
