Consider Nutritional Influences


FORT COLLINS, COLO. (Dec. 2, 2008) — Environment and nutrition play an important role in reproductive success in a beef female, Rick Funston, University of Nebraska Extension reproductive physiologist, reminded participants at the 2008 Robert E. Taylor Memorial Symposium: Applied Reproductive Strategies in Beef Cattle in Fort Collins, Colo.

Funston discussed the importance of selecting for a balance of traits, but he emphasized that producers must also select traits that match animals to their environment.

Reproduction is the most important factor affecting profitable beef production, said Rick Funston, University of Nebraska Extension reproductive physiologist. Funston discussed how nutrition is a key influence on reproduction.

Crossbreeding can be a valuable tool in achieving herd longevity, calf weight per cow exposed and net profit per cow exposed, he noted. But, he also cautioned that it’s not as simple as putting two breeds together. Instead, he stressed that producers must be attuned to a cow’s nutrient requirements in order to achieve reproductive success within the herd.

Most importantly regarding nutrition and reproduction, Funston said that research indicates, “It is better to have cows and heifers in good condition before calving than to play catch up after calving.” He recommended that cows be in a body condition score (BCS) of 5 to 6 prior to calving.

To that end, he said, “Balanced nutrition is the key to optimizing production.” On his list of nutrients to consider were protein, energy, minerals, vitamins and water. Some tips that he highlighted to achieve this balance:

There is no quick fix for reproduction challenges brought on by poor nutrition, Funston emphasized. “There is no magic feed ingredient that exists to compensate for a diet deficient in any of the mentioned nutrients or poor BCS.”

The Robert E. Taylor Memorial Symposium is conducted by Colorado State University every other year to provide current, research-based information for improving profitability in the beef cattle industry. The ARSBC program was developed by the Beef Cattle Reproduction Task Force to improve understanding and application of reproductive technologies, including AI, estrus synchronization and factors affecting male fertility. In 2008, CSU and the Task Force collaborated to provide the Dec. 2-3 symposium in Fort Collins.
