it was more the medication side, such as TB testing - is their a set time in the year or anything else, despite living around cows i really am clueless 
TB testing is another big question. Different parishes have different testing intervals (1, 2, 4 years) , a farm which has had a reactor will have to be tested again in 60 days, etc. We're a TB4; every 4 years Defra tell us they want us to be tested, we arrange a mutually convenient day with the vet in the next couple of months. I assume that if you are tested every year or more frequently, you will have more of a schedule - but perhaps someone who knows can tell you that.
Meds will depend a bit on the area; it's flukey here so cows are fluked as they come in for the winter and may be fluked again during the late summer if it's a wet one. We put a bolus into the stirks as they are turned out, this is a slow-release wormer and will keep them covered for their first season outdoors. Lungworm is a problem with cattle, especially youngstock, in addition to the same types of worms sheep get. We're mineral-poor soils here, so most cattle will get a mineral drench at some point - on turnout perhaps.
If the beef breed(s) are horned, there may be disbudding and / or dehorning to think about. Disbudding is done on young calves less than two months old, dehorning not in summer (flies) or winter (frosts) and cannot be done on a very young animal as there is not enough horn to grab hold of.
Most farms will castrate the male calves, either with rubber rings like lambs in the first week or using a burdizzo at about one month old. Any older than two months and it's a vet job.
