A cow is usually bred to give birth when she turns two, at this time she is fully mature and ready to produce. After that she can have one calf every year. Depending on genetics, she can still be producing calves by the age of 7-9.
So with 80 head of cattle, we have a 1:3 ratio of dairy to beef, respectively. That translates to: for every head of dairy cattle there are three beef cattle. Since, mathematically, 80 total head of cattle with a 1:3 ratio don't really work out to nice, round numbers, we will have to work with fractions and such. 1:3 ratio can be converted to a fraction: 1/3. 1/3=0.3333333... So, with 80 head of cattle, we find the number of dairy cattle: 80 x (1/3) = 26.66666666.... Which we could round off to 26 dairy cattle. Since we have 80 total head, we subtract to find how many beef cattle are in the herd: 80 - 26 = 54. So the answer is thus: If there are 80 head of cattle, and the ratio of dairy to beef cattle is 1:3, then there are 26 dairy cattle and 54 beef cattle.
None. Oxen are castrated male cattle that are used for pulling carts, wagons, plows, etc. and thus do not produce any offspring.
dairy cattle. 'Dairy cattle' just describes milk-giving cattle in general, and covers many breeds. Some people would say that Channel Islands cattle give the best milk.
Koalas produce a single offspring, just once a year. On rare occasions, they may produce twins.
2-6 offspring
Koalas produce a single offspring, once a year. On very rare occasions, they may produce twins.
Because the breed needs to keep producing offspring if breeders are to keep the breed from going extinct. Cattle don't live forever, and offspring need to be produced to keep the breed alive for many many years to come.

They produce many offspring
Koalas produce a single offspring, once a year. On very rare occasions, they may produce twins.
Chlamydiae reproduce by binary fission, producing two offspring.
No, only the "female cows" do. Male "cows" are not cows. They are bulls or steers, which do not produce milk. Female bovines that have had a calf (or at least two) are called cows and those cows produce milk. Young female bovines that have not had a calf are called heifers, and they are not able to produce milk because they have not had a calf yet.
