When to breed a bull and do you have to...

Thanks for all the GREAT advice..you guys rock and as I already said ...the plan of the bull is of the table. Where I am at in Texas any pasture does not fit the label “decent” with the draught we are in so it will always be a struggle for any cow.I really like hickerbillywife’s comment what gives me hope.I may should try one steer and one heifer instead. Yes I am definitely a beginner and here to learn from you guys in many ways. Also my English you have to bare as it is for me a second language what is far from perfect but hey whom is………??

dirkwood, if hay isn't too pricey in your area, I would get a couple of steers and keep them in hay if your field can't feed them. The manure and uneaten hay will help get the field/soil in better shape. Every year you do this your field/soil/grass should be improving. Get a cattle panel and hook it to the back of your riding lawn mower/4-wheeler/truck/tractor and drag it around the field occasionally to bust up the manure piles. If your fencing is adequate, sheep or goats are an option to (no need to drag the fields). Even if you don't eat them, they are bringing a good price. Take the money from selling them and buy you some beef.

Thanks Melissa....sheep are difficult here...they all get some sort of a parasite and get sick and goats would ruin the pasture I have worked on for a few years without animals on it.(I did had a couple of Donkeys before that)After them I have been cultivating with a real one, seeding and fertilizing so now I have for Texas standards a good pasture en will try to keep it like that. I think dividing my pasture and rotational grazing will do fine for 2 Dexter's so going to be trying that as soon I got all the fencing and gates done.
