Dr. Mike Hutjens Discusses Alfalfa Vs. Corn Silage in Hay and Forage Grower

March 23rd, 2011 by Courtney Beck

For many years, producers have turned to alfalfa haylage as their forage choice for dairy cows. However, corn silage has established itself as a choice as well. Both alfalfa and corn silage help optimize digestion and fermentation, while reducing feed costs. So how does one plant rank against the other and why are more producers leaning towards corn silage for dairy forage?

In a February article in Hay and Forage Grower, recently retired University of Illinois dairy scientist Michael Hutjens gives the inside scoop on the pros and cons of corn silage and alfalfa. Click here to read Dr. Hutjens’ full article on “Alfalfa vs. Corn Silage”.

University of Illinois to offer online dairy courses

December 17th, 2010 by Karlie Justus

The University of Illinois is offering a series of online courses for feed industry representatives, dairy farm managers and other dairy professionals.

Developed by the university’s Department of Animal Sciences, course material will cover applied research and knowledge of the dairy and feed industry using case studies that test the knowledge of principles learned in class. The upcoming spring semester course Advanced Dairy Nutrition 423 will be taught by Dr. Michael Hutjens.

The courses offer undergraduate and graduate credit, continuing credit for veterinarians, and professional training for feed industry representatives and dairy farmers. To register as a non-degree student, click here.

BASF Plant Science Recognizes Dr. Michael Hutjens through $2,000 Donation to University of Illinois Scholarship Fund

October 14th, 2010 by Karlie Justus

RESEARCH TRIANGLE PARK, NC, October 14, 2010 – BASF Plant Science announced a $2,000 donation to the University of Illinois at Urbana-Champaign Department of Animal Sciences during the 2010 World Dairy Expo in Madison, Wis. The donation, which recognizes retiring professor Dr. Michael Hutjens for his contributions to the dairy industry, will establish the “Michael F. Hutjens BASF Graduate Student Travel Awards” scholarship fund.

BASF Plant Science manager of nutrition and technical service Jerry Weigel announced the donation while introducing Dr. Hutjens at the “Managing Feed Costs 2010” seminar during the World Dairy Expo.  The seminar was his last prior to retiring, and was delivered to a packed room of dairy producers, nutritionists and other dairy stakeholders.

The “Michael F. Hutjens BASF Graduate Student Travel Awards” fund will grant $500 travel scholarships to exceptional graduate students, two each in 2011 and 2012, whose research and career interests are in dairy cattle nutrition and management. The funds will cover travel and other expenses associated with attendance at the American Dairy Science Association (ADSA) meetings.

“We are pleased to support dedicated students in the University of Illinois Department of Animal Sciences and demonstrate our appreciation of Dr. Hutjens’ service to the dairy industry,” said Weigel. “The scholarships will allow Dr. Hutjens’ contributions to continue to grow even after his retirement.”

Dr. Hutjens, professor at the University of Illinois at Urbana-Champaign, 2008 American Dairy Science Fellow and 2008 World Dairy Expo Industry Person of the Year, has provided significant developments in dairy nutrition and research. In his 2010 World Dairy Expo seminar, Dr. Hutjens discussed strategies for evaluating forage inputs, building rations for optimal performance in high-producing cows, and determining nutrient levels and forms.

At the World Dairy Expo, BASF Plant Science and NutriDense Silage also gave away four 50-yard line tickets to the Green Bay Packers vs. Minnesota Vikings game as well as free cheese sandwiches and milkshakes from the University of Wisconsin at Madison’s Dairy Badger Club Cheese Stand.

NutriDense Silage is nutritionally enhanced corn silage developed specifically for efficient milk production. University studies show NutriDense Silage provides a four to eight percent improvement in feed efficiency, or converting feed to milk, giving dairy producers an income over feed cost advantage. The result is lower feed costs and greater profitability for dairy producers. NutriDense Silage yields equal to or greater than dual purpose and greater than brown midrib, so producers can achieve high-quality corn silage without sacrificing yields.

Feed Efficiency: Effect of Corn Silage Quality and Hybrid Selection

August 11th, 2010 by Rich Lutz

Feed costs in dairy rations are no doubt the largest single expense associated with milk production, as often they can average in excess of 50% of production costs.  Feed Efficiency (FE), also known as milk production efficiency, is often utilized to benchmark herds in terms of their relative profitability.

Hutjens (2007 and 2010)1, 2 offers practical approaches to feed efficiency and their applications on dairy operations.  With regard to silage quality contributing to feed efficiency, Hutjens points out the following:

  • As neutral detergent fiber (NDF) percent in the ration dry matter increased, FE declined from 1.8 to 1.4 based on Journal of Dairy Science data from 2002 to 2004.  FE values remained constant at 35 percent NDF and above.
  • Currently, with herd FE ranging from 1.4 to 1.7, each change in 0.1 point is worth approximately 34 cents per cow per day.
  • Feeding high-quality forage is a key solution.  Consider increasing corn silage levels in rations as cost per cow per day may drop 15- 30 cents as protein prices remain competitive.
  • Evaluate the use of silages with more effective fiber and high neutral detergent fiber digestibility (NDFD).

For more practical tips on increasing feed efficiency, click here to read the paper.

Additionally, feeding corn silage hybrids with increased fiber digestibility has been shown to significantly increase FE in dairy herds.  Spain and Sampson (2007)3 published findings determining the feed values and ultimate effect on FE utilizing a corn silage hybrid with NutriDense Silage traits:

  • Cows fed NutriDense Silage produced 71.7 pounds/cow/day compared to 70 pounds/cow/day for cows receiving conventional corn silage.Based on dry matter intake, cows receiving NutriDense Silage were 11.4% more efficient than cows fed conventional silage (1.56 vs. 1.4).
  • In related in vitro work, Spain and Sampson observed a 13% increase in the production of volatile fatty acids (VFA) with NutriDense Silage when compared to conventional silage.
  • This positive measurement of fiber utilization supports that NutriDense Silage contains favorable fiber for energy contribution to the overall TMR used in the feeding trial.

More recently, Chase (2010)4 conducted a trial with lactating dairy cows to examine the relationship between corn silage hybrid fiber digestibility, milk production, dry matter intake and feed efficiency.  Results demonstrated that:

  • Cows fed NDS had significantly better feed efficiencies when compared to cows receiving either BMR or conventional hybrid silages.Feed efficiency (kg 3.5% fat corrected milk/kg dry matter intake) was significantly higher for cows fed NDS (1.87) compared with either BMR (1.76) or conventional (1.74) rations (P<0.002).
  • Dairy consultants utilizing FE numbers to evaluate dairy production profitability may wish to consider how silage quality and hybrid selection can affect those values.
