  • 1 November 1999
The transition period, from 3 wk before to 3 wk after parturition, is critically important to health, production, and profitability of dairy cows. Most health disorders occur during this time.Expand
Adaptations of Glucose and Long-Chain Fatty Acid Metabolism in Liver of Dairy Cows during the Periparturient Period
Tremendous metabolic and endocrine adjustments must be made as dairy cows move from late gestation to early lactation. Requirements for glucose and metabolizable energy increase two- to threefoldExpand
The development, nutrition, and management of the young calf
This volume examines the raising of dairy calves, giving an account of all aspects of calf rearing from the rudiments of anatomy and development through the practicalities of feeding and housing.Expand
Nutrition during the dry period and hepatic lipid metabolism of periparturient dairy cows.
From dry-off until 7 d before expected parturition date, 30 Holstein cows were fed a low energy diet (control) to maintain body condition or high energy diets (high fat or isocaloric high grain) toExpand
Identification of a missense mutation in the bovine ABCG2 gene with a major effect on the QTL on chromosome 6 affecting milk yield and composition in Holstein cattle.
We previously localized a quantitative trait locus (QTL) on chromosome 6 affecting milk fat and protein concentration to a 4-cM confidence interval, centered on the microsatellite BM143. WeExpand

The general principles of growth and nutrients required are no different for young calves than for any other species. Additional complexity is introduced, however, by the need to transition the youngExpand
Growth and body composition of dairy calves fed milk replacers containing different amounts of protein at two feeding rates.
Previous research has demonstrated that increasing the CP concentration from 16 to 26% in milk replacers fed to male preruminant dairy calves at 1.5% of BW (DM basis) daily resulted in increased ADG,Expand
Diets during far-off and close-up dry periods affect periparturient metabolism and lactation in multiparous cows.
The objectives of this study were to determine the effects of far-off and close-up diets on prepartum metabolism, postpartum metabolism, and postpartum performance of multiparous Holstein cows. FromExpand
Growth, nutrient utilization, and body composition of dairy calves fed milk replacers containing different amounts of protein1
Abstract Male Holstein calves <1 wk of age were allowed a 2-wk adaptation period after purchase, and then were blocked by BW and assigned randomly within block to either a baseline slaughter group orExpand
Effects of yeast culture (Saccharomyces cerevisiae) on prepartum intake and postpartum intake and milk production of Jersey cows.
Yeast cultures (Saccharomyces cerevisiae; YC) have been added to diets for dry and lactating dairy cows to attempt to improve ruminal fermentation, potentially increasing dry matter intake (DMI) andExpand
