Journal ArticleDOI
Experiments on the nutrition of the dairy heifer: VIII. Effect on milk production of level of feeding at two stages of the lactation
TL;DR: The higher level of feeding increased yields of milk and milk solids and solids-not-fat content in each period but had a smaller effect in mid- than in early lactation, a trend which was shown to continue further into later lactation.
Journal ArticleDOI

Journal ArticleDOI
Experiments on the nutrition of the dairy heifer:IX. Food utilization in lactation
TL;DR: Animal-to-animal variation in output on constant diets was characterized by negative regressions of live-weight change on milk yield, which was greater in early than in mid-lactation but they were constant in size at any one time for the various groups.
Journal ArticleDOI
Influence of plane of nutrition and diet composition on rumen fermentation and energy utilization by dairy cows
TL;DR: It is suggested that both the reduction in milk fat concentration and the increase in milk yield in response to reductions in the fibre content of diets may be independently related to the increased in the proportion of propionate in the rumen VFA.

TL;DR: Greater compound content of the diet and larger daily allowance of DE were associated with increased occurrence of mastitis and lameness but not digestive upsets, and little cumulative effect was observed on either milk fat yield, or concentrations of fat and SNF in milk.
