National Cattle Evaluation has never been static, and future changes are inevitable as science continues to advance.
Recent research has shown maternal nutrition during late gestation can have lasting impacts on calf health, growth, and performance postnatally. These impacts can include improved weaning weights, yearling weights, and marbling scores of progeny.
Since 1993, the U.S. Meat Animal Research Center (USMARC) has produced a table of factors to adjust Expected Progeny Differences (EPDs) so that the genetic merit of individual animals can be compared across breeds. These adjustment factors are needed because EPDs published by one breed are inherently not comparable to those published by another breed.
A resource reality of cattle production is that only 10-30% of the nitrogen (N) that is consumed (i.e. fed protein) is utilized by animals for growth, reproduction, milk production, and maintenance needs. Unused N is excreted, primarily in urine. Nitrogen is an essential, valuable plant nutrient, so recycling of N is highly desirable and occurs when urine and feces are applied directly onto soil in a pasture, range or other grazing scenario, or collected manure is applied to cropland.
In this month's BeefWatch Producer Perspective Podcast, Brock Terrell from Hay Springs shares how his family added a sheep enterprise to their operation. Some of the topics that Brock discusses in the interview include:
