Well let me start by stating that this is our first calving season, which will lead into our first breeding season.
We are evaluating which breeding program to go with. We know of several potential programs.
The first is simply pasture bull breeding. Due to the presence of young kids on the old homestead, we have not seriously considered this as an option.
The next method would be a timed breeding program , which would require hue use of prostaglandins and follicle stimulating hormones. Seeing that we are trying to go with a hormone free program, this is off the table as well. So what should we do?
The best breeding programs are reliant on heat detection. This can be noted through observation or left to the bull if one is around. The issue facing most farmers is that they are too busy to simply sit on the fence and watch for evidence of heat. These behaviors include increased walking activity, mounting behavior, and willingness to be mounted. Typically a cow that is willing to be mounted is ready to be bred, the cow doing the mounting is about 12 hours away.
I think that we are going to go with some kind of marker-type system. This can be a simple as tail chalking. This method uses chalk to mat the hair over the tailhead down. Once the animal is mounted, the hair stands up, so that it is evident that she is in heat. Another form of the marker system is called a Kamar pak. This is a dye pack that is fixed to the tailhead region. Once the animal is mounted, the dye pack is broken and changes color to alert you to the presence of a breedable heat.
After compiling the above from the vast knowledge contained within my head (Said with tongue in cheek sarcasm), I found the following website, which may be more helpful.

I found this to be a great resource. It is organized well and goes through the possible management systems that are available.
