Ad libitum intake is achieved by offering a diet at amounts in excess of expected consumption; however, the amount of excess may alter the intake of certain diets and challenge this definition of ad libitum intake. The objectives of these trials were

Opaque-2 corn (Zea mays L.), more commonly known as high lysine corn, contains more lysine than normal corn. However, little is known about the digestibility in ruminants of different high lysine hybrids. Objectives were to determine in vitro ruminal

The objective of this study was to determine the effect of forage fiber digestibility as part of a total mixed diet on intake and production of cows with intakes that were likely limited by rumen fill, using treatments that were not confounded by fib

Twelve Holstein cows (63 DIM; 6 primiparous) were offered a common diet and monitored for 21 d (11 d of adaptation, 10 d of collection) with a data acquisition system to measure continuously feed and water intakes and chewing behavior. Objectives wer

The monitoring of feeding, chewing, and ruminal activity was integrated into one data acquisition system for continuous measurement of 12 dairy cows. Feed mangers were hung from single-point load cells for measurement of feed disappearance from indiv

Twelve multiparous, rumen, cannulated cows (17 DIM) were fed 25 or 35% NDF diets without or with added rumen-inert bulk as water-filled plastic containers (500 ml each) within three 4 × 4 Latin squares (21-d periods). Added bulk equaled 25% of pretr

Dietary requirements for NEL and absorbed true protein were summarized for marginal production of milk components because of genetic improvement through selection. Shelled corn and soybean meal were used to meet marginal nutrient requirements and wer

Objectives were to develop a system of equations for formulating rations to meet absorbed protein requirements, to define NEL requirements for individual milk components, and to evaluate the effects of changes in milk composition on requirements for
