JERSEY
ORGANIZATIONS ALLOCATE NEARLY $30,000 FOR
SCIENTIFIC STUDIES IN 2006 Reynoldsburg,
Ohio, March 20, 2006—The AJCC Research Foundation and National
All-Jersey Inc. (NAJ) have committed grants totaling $29,500 for five
scientific investigations related to Jersey dairy cattle for 2006. The
funded projects were selected from nine (9) proposals addressing six
major topic areas received in response to the Foundation’s annual
Request for Proposals. With this year’s grants, a total of $587,500
has been awarded for Jersey-specific research in the past 16 years by
the Foundation and the national Jersey organizations. Studies
Funded by AJCC Research Foundation The
largest grant, $8,000, was made to Dwight K. Roseler and Tom Earlywine
of Land O Lakes Animal Milk Products Co. and Purina Feeds, working in
cooperation with Christopher Reynolds of the Agriculture Research and
Development Center of The Ohio State University. Recent field research
by Dr. Roseler indicated that approximately 20% of Jersey cows in
high-producing herds fail to produce at least four quarters of first
milking colostrum. This study will identify specific areas of nutrition,
environment, housing or management that are correlated with first
milking colostrum quantity. This information will then be used to
provide recommendations for cow herd management for better calf survival
and health. A
grant of $7,500 was allocated for a study of feed efficiency in Jersey
and Jersey-cross cows being conducted by Randy D. Shaver of the
University of Wisconsin, Madison. Because of their smaller body size and
high milk component yields, Jersey and Jersey-Holstein crossbred dairy
cows may offer potential for improved feed efficiencies, but this has
not been documented. The trial will be conducted over at least a
one-year period so that seasonal, days in milk, and dietary effects on
feed efficiency measures can be evaluated. Daily milk weights for
individual cows, monthly body weights and body condition scores for
individual cows, daily dry matter intake (DMI) for pens, and weekly milk
composition for pens will be determined. Impact of changes in feed
efficiency over time will be evaluated in terms of economic performance. Michael
A. Ballou and Edward J. DePeters of the University of California, Davis,
received funding of $5,000 for their ongoing research program related to
Jersey calf immunity. The new study will evaluate the immune competence
of Jersey and Holstein calves, evaluating the innate and adaptive immune
responses of both breeds as well as response to Salmonella
typhimurium endotoxin. Bennet
Cassell of Virginia Polytechnic Institute and State University,
Blacksburg, received an award of $4,500 for a study of energy balance
and its relationship to health, productivity, and fertility for first
lactation Jerseys, Holsteins and their reciprocal crosses. The results
will be used to compare economic returns from each of these groups and
may have implications for the market value of the Jersey breed as well
as breed improvement programs. Studies
Funded by National All-Jersey Inc. The Board of Directors of National All-Jersey Inc. approved a $4,500 award for the project submitted by Richard A. Zinn of the University of California, El Centro, to characterize feedlot growth performance of Jersey steers. This study will provide new information related to the pattern of growth under modern feeding conditions (high energy growing finishing diets, and growth implants); mature weight; changes in dressing percentage, ribeye area, fatness, and marbling score with respect to mature weight; and assessment of energetic efficiency. About
the AJCC Research Foundation
Founded
in 1967, the AJCC Research Foundation has provided seed money for
well-designed scientific investigations related to high-priority areas
affecting the Jersey breed of dairy cattle:
An advisory committee that includes Jersey producers, dairy scientists, and allied dairy industry representatives evaluates proposals. The final decision on funding is made by the Directors of the American Jersey Cattle Association. The
next Request for Proposals will be issued in August, with projects due
by December 1. Detailed information about the Competitive Grants Program
can be found on the web
site or requested from Cari W. Wolfe, Director of Research and
Genetic Programs Development, at 614/861-3636.
