I started with dairy animals and quicky learnt the hard way dairy is expensive.
I came across some cheap cows and jumped in head first.
PROBLEM #1: Feeding
Dairy cows EAT in large quantities and need a lot of space. Bales are not an option, you need real grass
PROBLEM #2: Dairy animals are fragile and fickle. They are very susceptible to tick borne diseases, mastitis and only produce enough when fed a balanced diet.
If pure milk volumes are affected by many variables including breed and temperature
PROBLEM #3: Dairy is a volume game. It's not the same having 5 cows as having 50 cows, the more milking cows you have the easier it is.
Milk buyers are only interested above a certain volume and having 10 cows is not worth their while from a volume perspective
