Four experiments were conducted (1961-1964) for the primary
purpose of studying the milk and milk constituent yields of dairy cows
under dry lot and pasture systems of management. The secondary
purpose was to compare the health and breeding performance of cows
under these two systems.
Ninety-eight cows of the Holstein...
Two experiments involving 33 Holstein cows were conducted
for the primary purpose of studying the effects of flumethasone (a
synthetic glucocorticoid) on milk and milk constituent yields. The
secondary purpose was to compare udder health, reproductive performance,
and body weight changes of cows on flumethasone therapy.
Nine Holstein cows were...
Evaluations of body form and measures of milk production were
recorded for 188 Holstein lactations and 77 Jersey lactations in the
Oregon State University Dairy Herds. Components of body form
included general appearance, dairy character, body capacity, and
mammary system and 34 sub-components of these four traits plus body
weight...
Two experiments were conducted to study the effects of
melengestrol acetate (MGA) on inhibition of estrus, post-treatment
conception rates in heifers and rats, and MGA given during gestation
on the reproductive performance in rats. MGA was administered
orally to Holstein heifers and by subcutaneous injection to Sprague-
Dawley rats.
