One thing that sets the beef industry apart from all
other animal agriculture industries is that there is no set breeding program
and/or universal cattle breed. Then within a breed there is about as much
genetic variation as there is between the breeds. Every breeder of livestock has
his/her own reason for choosing the bulls they use; we are no different. Because
we calve in May/June, which is right before peak grass growth here in the Peace,
we have an interesting set of circumstances to deal with.
First of all: We hate having multiple breeding herds because it interferes with managing our pastures. So we graze all our pairs as one herd. This allows us to have a high intensity; short duration grazing system with long periods of rest. The result has been an increase in the carrying capacity and better health of our pastures. To get around the problem of one big herd which one bull cannot cover we rely on AI for the first 21 days of the breeding season. This way over 3/4's of the cows are bred before the herd sire gets a chance. We used to use the CIDR technology for synchronization of our mature cows with not bad results. However CIDR's were labor intensive, stressful on cows, hard on the bull (when all the cows that did not catch from the AI came around in a 4 day window) and most of all: it costs money. Now we use visual heat detection and are getting even better AI conception rates and I am paying myself to do it.
Our in house Spirit View Herd Sires all come from Elite cows within our herd.
The dams of these sires are 1200 - 1300 lbs and always care good to excellent
flesh at weaning. They are all very feminine, at least 8 years old or older,
have perfect udders and feet and they are all the type that every rancher wishes
he had 100 of. Because these bulls are not used till they are 2 years of age -
they have no problem covering the rest of the cows that I did not catch.
I was once told, "There is nothing wrong with doing something - as long as you can justify what you are doing; if you are doing something simply because someone else is doing it - it can not be justified"! |
