Milk production can be increased by managing dairy cows’ exposure to light. Photo period is defined as the duration of light exposure within a 24-hour period. A long-day photo period (LDPP) means exposure to 16–18 hours of continuous light followed by 6–8 hours of continuous darkness. A short-day photoperiod (SDPP)...
Our objectives were to determine if dietary cation-anion difference (DCAD) and source of anions influence periparturient feed intake and milk production, and to characterize feeding behavior of dairy cattle during the transition period. Diets differed in DCAD (cationic or anionic) and anionic supplement (BioChlor®, Fermenten®, or anionic salts), and were...

The objective of this study was to evaluate triticale
grain fed as a concentrate in the diet of high producing
dairy cows. A lactation study, in vitro dry matter
digestibilities and a preliminary physiological effects
trial were conducted to evaluate triticale and used to
make feeding recommendations.
In the lactation...
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...
