    Country                          Many Oklahoma ranchers choose to breed the replacement heifers about a month
                                     ahead of the mature cows in the herd. In addition, they like to use a shortened 45 to
    Short Term Calf Removal    3     60-day breeding season for the replacement heifers. The next logical step is to deter-
                                     mine which of these heifers failed to conceive in their first breeding season.

                                        herd. Lifetime cow studies from Montana indicated that properly developed heifers
                                        that were exposed to fertile bulls, but DID NOT become pregnant were often sub-
    Lane Ag Center Field Day      5     fertile compared to the heifers that did conceive. In fact, when the heifers that
                                        failed to breed in the first breeding season were followed throughout their life-
                                        times, they averaged a 55% yearly calf crop. Despite the fact that reproduction is
                                        not a highly heritable trait, it also makes sense to remove this genetic material
                                        from the herd so as to not proliferate females that are difficult to get bred.

     Oklahoma is Cattle Country
Oklahoma plays an important role in an industry that is extremely huge and complex. Oklahoma, along with Kansas,
Nebraska and Texas, has a diverse cattle industry with large components of all the major live animal production sectors.
As is clear from the following lists, Oklahoma ranks in the top ten states for cow-calf production, stocker production and
feedlot production.

A careful look at these lists also reveals something about the complex flows of animal and distribution of cattle produc-
tion around the country. Beef cattle productions occur all across the country in a wide variety of production environ-
ments. Animals tend to move towards the center of the country as they move toward feedlot finishing and generally be-
come more concentrated geographically. This is evident in the lists above where the top ten cattle feeding states have
nearly 86% of total cattle feeding while the top ten cow-calf states represent less than 60% of the total. Stocker produc-
tion is also more concentrated in the middle of the country but is somewhat harder to see. However, the list of top ten
states of estimated feeder supply indicates some significant movements of cattle after weaning. For example, Missouri
drops to fourth while Oklahoma moves from third to second. Oklahoma has 6.2% of beef cows but has 8.2% of feeder cat-
tle, which indicates movement of cattle into Oklahoma. By contrast, Montana, which ranks seventh in beef cows, does
not even appear on the feeder supplies list, which indicates large movement of feeder cattle out of Montana after wean-
ing.

Herbicide Spray Container Program Expanded for Summer 2003
The Choctaw/Pushmataha County OSU Cooperative Extension Service is very pleased to announce that
the Herbicide Spray Container Program has been greatly expanded for the summer of 2003. Instead of
having the collection on just one day in the local communities, it has been expanded from June 1st thru
August 1st. This will give producers 2 full months to rinse the barrels or containers and drop them off at
four collection sites at their convenience. Thanks to the cooperation of the local feed stores they will be
an empty van trailer that will be set aside just for rinsed spray container collection. The collection pro-
gram will be run on the “honor system”. It is the responsibility of the producer to triple rinse the con-
tainers (barrel or 21/2 gallon jug) to remove the label and the lid. If we get too many un-rinsed and dirty
containers we will discontinue the program. With everyone cooperating we hope that this program will
be even more successful at removing and recycling spray containers. The feed stores that are participating
in this program are:
