Glad the FEL driver for T posts worked for you... I think you have the idea down now... all you need to do is get a piece of pipe just larger thana T post, weld a solid end on it, cut it to length so bottom of pipe just kisses ground when T post is driven to proper depth... and, you have solved the bent post problem as well as "how far do I drive it?"
AI is an interesting experience.... theory is better than practice.. UNLESS, you are there, DAILY, to determine when an animal is in standing heat and do the AI in the proper 6 hr window... labor intensive. Yes, synchronization can be done too.... any AI technique you try, regardless of efforts at superb management, will meet with limited success. Best efforts will result in a 60% pregnancy rate.... and you will need to AI again, or use a clean up bull. Result will be that it is impossible to have a concentrated breeding/calving period. If all your cows are not calving at the same time, then your AI efforts will be similarly spread out... all over the calendar... and calving intervals will slip and slip.. not for every cow, but more so than if you were only using bulls. AI can be used to reduce the number of bulls required, total. However, unless you have so many cows in heat at once (maybe 4 or more a day) that they start shooting blanks, you really don't need AI for that reason.
The only reason for AI, best I have determined, is to have calves that you can sell that are from "that great xxx bull" and "famous cow of mine" . If you can develop a market for such animals, at a profitable return for cost of straws, your labor, lost oportunity time, etc... that is dandy.
Try it, but I am betting you won't stay with it for more than a couple of years, if that. Your partner when he finishes his degree will be far smarter than I am and will surely want and need to put his degreed learning into practice... and he should... it's a graduate program....
These folks
Capitol Land and Livestock
are where I sell my calves... they collect from all over the area, are extremely vertically integrated, background animals until ready, have lots of cattle trailers and deliver trailer loads to feeders, etc... What you are trying to do is to match their operation.... they are superb at what they do.. worth studying.
Suggest you have a HEALTHY trailer before you start hauling buffalo! Glad you respect them already!
