An experiment was conducted with 27 multiparous Holstein and 27 multiparous
Jersey cows to determine if nicotinic acid (NA) supplementation during the prepartum
phase of the transition period decreases lipolysis and improves dry matter intake and
to determine if Holstein and Jersey cows respond similarly to NA supplementation.
There is growing public concern about the high proportion of saturated fatty acids in milk fat; however, feed intake, energy partitioning toward milk synthesis, and milk fat concentrations can decrease when cows are fed high concentrations of unsaturated lipids. The objective of this study was to identify the optimal rate...
Three studies during three consecutive summers were conducted
at the Squaw Butte Experiment Station to estimate relative and quantitative
forage intake of spring and fall calving cow-calf pairs on
summer range. In a drylot study (experiment 1) individual animal
consumption of fescue or meadow hay cut at 2- to 10-day...
The objectives of this study were to determine the diets of
cattle at risk to DABPE on stress and inciting pastures and to determine
if segregated feeding groups of cattle displayed differential
susceptibility to DABPE.
Stress pastures were classified and mapped by plant communities
and segregated feeding group areas. Cattle...
Rapid copper depletion without clinical symptoms of copper deficiency
was found in cattle under natural Klamath basin conditions.
Copper metabolism was influenced by grass species fed to the animals.
Tall fescue, Festuca arundinacea Schreb. 'Altar and 'Fawn', reduced
liver copper stores and decreased blood plasma copper and ceruloplasmin
Pangola digitgrass (Digitaria decumbens), Coastcross-
1 bermudagrass (Cynodon dactylon), and Kazungula
setaria (Setaria sphacelata cv Kazungula) were used in a
two-year study at the C.A.M.P.A. Training Center in
Tampico, Mexico. The objective of the study was to determine
the optimum stocking rate during the grazing season
on these species and...
