Even if you interested in fresh milk and eggs, breeding food animals means that once they will be slaughtered. The main rule among farmers is to never give names to your animals. But it will be very hard to you if you have two or more animals and you must discern them. At least try not to give them affectionate names. That will be a good advice to use numbers for calling your animals.
In addition to emotional preparation dealing with butchering includes prowess in prescribed procedures which will provide tasty and tender meat. If you can`t butcher your wards ask for help from your neighbor who has his own livestock or from professional slaughterhouse.
If you want to raise a goat or cow for dairy production you should know that your animal will give milk only after lactate. The main advantage to breeding livestock only for meat is that the project can be short. For example broiler chickens can be raised for about 8 weeks, lambs can be ready in 6 or 7 months.
