if you are a beginner ... chickens.
More than a few, just in case!
for all rounders, goats definitely fit the bill. Milk, less space needed than cattle, less suicidal than sheep (or so I'm told, I don't keep sheep so should stick to telling you what I know about) intelligent, affectionate, generally few kidding problems (assuming you want them for purpose, ie to milk from) and, if you do your homework, buy good, tested stock, then usually little need for vet attention, with good husbandry.
depending on your land, pigs give good meat.
cats or terriers will keep down the rodents ...
.. after that, its a case of what you fancy keeping really!
best of luck
