Research Report [rom NMSU
NMSU was represented at the 65th annual meeting of the American
Dairy Science Association in Gainsville , Florida, on June 28 to July 1
by' Dr. D.W. Kellogg, Assistant Professor, who reported on Effect of Sodium
Butyrate in a High-Grain Ration on Milk Production and Comoosition.
Results of his work indicated that sodium butyrate had no effect on milk
yield . It also produced no effect on milk solids_not_fat content. There
was a significant reduction in milk fat yield with sodium butyrate compared
with the high_grain ration . Butyrate compounds are known precursors of
milk £at . but apparently were not limiting fat yeild in these rations.
The cows were receiving less than five pounds of hay daily . Therefore,
the rate of grain consumption was extremely high .
A second experiment has shown that apparently part of t,he negative
effect of sodium butyr'ate on milk fat was due to the pelleting of about
101. of the milo with sodium butyrate . The pelleting was necessary to
achieve tD4ximum intake of grain with sodium butyrate.
Some Highlights of Papers Presented at the 65th annual meeting of the
American Dairy Science Association
C. L. Pelissier of the University of California reported on some
factors contributing to low breeding efficiency in dairy herds. Breeding
record analysis of 5,000 cows revealed an average conception rate of 43.37.
on first service and an average of 2.67 services per conception. He found
that one out of every six heat periods was either missed or not rec orded
subsequent to the first recorded heat period . A wide between-herd range
was found .

Object Description
| Title | Dairy Herd Improvement Notes, August, 1970 |
| Series Designation | Dairy Herd Improvement Association Monthly Report |
| Description | The monthly report of the Dairy Herd Improvement Association (DHIA) was initiated by E.E. Anderson, Extension Dairyman in the 1940s. From the 1960s forward a cooperative report had been prepared jointly by staff members of the NMSU Dairy Department, Agricultural Engineering, Agronomy, Veterinary and sent primarily to dairy herds on test (OS, DHIA, DHIR), County Extension Agents, and Instructors of Vocational Agriculture. The publication of the DHIA report was overseen by Philip Leyendecker, a director of the NMSU Agricultural Extension Service in cooperation with U.S. Department of Agriculture. The title of the report had changed over time; it had a couple of variations, New Mexico Dairy Herd Improvement and Dairy Improvement Notes. This digital collection includes historical issues published between 1961 and 1980. |
