Over 100 years, the Journal of Dairy Science has recorded incredible changes in the
utilization of fat for dairy cattle. Fat has progressed from nothing more than a contaminant in …

Blood flow and net nutrient fluxes for portal-drained viscera (PDV) and liver (total splanchnic
tissues) were measured at 19 and 9 d prepartum and at 11, 21, 33, and 83 d in milk (DIM) in …

Fat is an important constituent contributing to the organoleptic, processing and physical
properties of ruminant milk. Understanding the regulation of milk fat synthesis is central to …

The efficiency of N utilization in ruminants is typically low (around 25%) and highly variable
(10% to 40%) compared with the higher efficiency of other production animals. The low …

An experiment was conducted to determine whether the susceptibility to ruminal acidosis, as
defined through differences in days in milk (DIM), milk production level, and ration …

Four multiparous Holstein cows were used in a 4× 4 Latin square experiment to study the
effects of fat sources rich in omega-3 fatty acids on milk production and composition …

A total of 90 lactating Holstein cows averaging 628kg (SE= 8) of body weight (BW) were
allotted at calving to 30 groups of three cows blocked for similar calving dates to determine …

Our objective was to determine the effect of feeding rumen-inert fats differing in their degree
of saturation on dry matter intake (DMI), milk production, and plasma concentrations of …

The objectives were to measure the effects of transition and supplemental barley or rumen-
protected protein on visceral tissue mass in dairy cows and the effects of transition and …
