Herd grassfed bull tests
The Rose Herd Project began
with the generous donation of an entire herd of Belted Galloways to the
newly established Belted Galloway Foundation whose mission is research
and education as it relates to the Belted Galloway breed of cattle. Some
of the young heifers in the herd were used in projects for the Beltie Youth
Group and the balance of the herd was moved to Malabar Farm in St. Charles,
Iowa for on-farm research in a forage-based operation.
1. Identification of those bloodlines which are best suited for a grass-based or partially grass-based, non-feedlot program.During the first full year of the project, quite a lot was accomplished. Complete measurements were taken of all of the cows in the herd. All bull calves from the 2002 calf crop were placed on a grass-based bull test and much data was collected on these animals. The purposes of the bull test were to identify which genetics within this herd did best, to design a template for an easily managed bull test which could be replicated, and to develop an indexing system rather than a strict average daily gain model for bull selection. The optimum level of production is rarely the maximum, yet most bull selection has been based previously on rates of gain. Typically bull tests in commercial operations are done by multiple producers who send their best animals to the test. By using the whole herd as the bull test, we were able to determine not only the best performing animals but also to see the range of performance of an “average” herd. These data can then become the benchmarks for others to use for comparison in their herds. Selection of the top performing bulls was done by developing an indexing system, weighting value-added characteristics more heavily. Ultrasound technology was a major tool in bull selection. Those bulls which were not selected will be harvested and the quality of their meat will be studied. At least two of the bulls which were considered superior were used on a limited number of females in 2003 and more extensively during 2004. A new bull test began in the fall of 2003 including bulls from the Rose Herd as well as from the Malabar Farm and Blossom Ridge herds. Another result of the Rose Herd Project has been establishment of a Beef Marketing Committee to study the best ways to market Beltie beef and to consider the possibility of a beef branding project. One question to be answered in this research is whether it is possible to make more money by accepting less production per cow and concentrating on managing grass and production per acre.
