What are the advantages and disadvantages of breeding cattle for a 3 month period vs. all year round?

Answer 1

Advantages- many of what the previous person answered. You can control when the calves are born and during what time of the year they are born. You also make it easier on yourself if all your cows calf at the same time or within a window of time. This way you are not having calves that are finished or ready to breed (depending on what you are doing with them) at all different times.
Disadvantages: If a cow does not catch during the three month period you will not get a calf out of her till next time. However, in my opinion you cows should be able to get pregnant when you need them to. If you have a cow that never catches you need to either consider AI or hormones or get her out of your herd. I guess also another advantage could be that you have calves that would finish out at different times. If you have a small operation perhaps this is something you might want, but it makes for more work.

Answer 2

From having lived in different parts of the U.S. , I would say three months a year for myself. Why? Okay, because you can control(to and extent) when the breeding and birthing season will be. You can also plan as to when the livestock will have to be fed and housed so as to have more live births in a barn rather than chance it out in the open where the weather, carnivores and other things(Yes, cattle rustlers do still exist) may be very much so present.
