ABSTRACT: Estimating the efficiency of N utilization for milk production (MNE) of individual cows at a large scale is difficult, particularly because of the cost of measuring feed intake. Nitrogen isotopic discrimination (Δ15N) between the animal (m

The effects of feeding calcium salts of poultry oil as fat supplement on feed intake, nutrient digestion, feeding behavior and milk production of dairy cows were investigated. Twenty four Holstein cows (BW = 589 ± 41 kg; DIM = 105 ± 26.7 d [range o

Heat stress is a major problem for dairy cows in hot climates, thus coping strategies are essential. This study evaluated the effects of increasing diet fermentability on intake, total tract digestibility, ruminal pH and volatile fatty acids (VFA) pr

This study investigated the effects of, and interactions between, dietary grain source and marginal changes in alfalfa hay (AH) particle size (PS) on digestive processes of dairy cows. A total of eight Holstein dairy cows (175 days in milk) were allo

Context Although several studies investigated the dairy cow performance in response to varying ratios of corn to barley grain, little attention has been paid to the forage component of the diet. We hypothesised that a diet based on corn silage with c

Background Normal feeding behaviours is one of the criteria of the health condition of dairy cows particularly in the condition of heat stress. Objective The study evaluated the effects of the ratio of pellets of wheat and barley grains to ground cor

This study evaluated the effects of feeding diets that were formulated to contain similar proportions of undigested neutral detergent fiber (uNDF) from forage, with wheat straw (WS) substituted for corn silage (CS), alfalfa hay (AH), or both. The die
