Fatty acid intake and rumen fatty acid composition is affected by pre-grazing herbage mass and daily herbage allowance in Holstein dairy cows
(Spanish National Institute For Agriculture And Food Research And Technology, 2014)
The objective of this study was to investigate the effect of level of pre-grazing herbage mass (HM) and daily herbage allowance (DHA) on the fatty acid (FA) intake and composition of ruminal content of grazing dairy cows. ...
Protein and Carbohydrate Fractions in Warm-Season Pastures: Effects of Nitrogen Management Strategies
(Mdpi, 2021-05-01)
Nitrogen (N) management affects herbage production and chemical composition; however, information on the impact of tropical herbage on N and carbohydrate fractions is scarce. A two-year study was conducted to investigate ...
Interaction between herbage mass and time of herbage allocation modifies milk production, grazing behaviour and nitrogen partitioning of dairy cows
(2019)
The objective of the present study was to evaluate the interaction effects between herbage mass and time of herbage allocation on milk production, grazing behaviour and nitrogen partitioning in lactating dairy cows. ...
Diurnal Concentration of Urinary Nitrogen and Rumen Ammonia Are Modified by Timing and Mass of Herbage Allocation
(2019)
The objective of this work was to evaluate whether changes in time of herbage allocation and herbage mass (HM) (low (L) or medium (M)) modify the diurnal pattern of urinary nitrogen (N) concentration and ruminal ammonia ...
Effect of daily herbage allowance restriction on pasture characteristics and milk production by grazing dairy cows in spring
(2018)
The cumulative effects of daily herbage allowance (DHA) restriction on pasture
characteristics and the sustainability of pasture-based dairy systems were evaluated. Sixty-four dairy cows were randomly assigned to one of ...
Relação planta-animal em diferentes intensidades de pastejo com ovinos em azevém anual (Lolium multiflorum Lam.)
(Universidade Federal de Santa MariaBRZootecniaUFSMPrograma de Pós-Graduação em Zootecnia, 2006-02-22)
This work aimed to evaluate the utilization of different grazing intensity on the productive and structural characteristics of pasture and on the ingestive behaviour and performance of sheep in continuous grazing. The ...
Pasture condition and milk production by grazing dairy cows as affected by daily herbage-allowance restriction
(2019)
Daily herbage allowance is recognised as the main tool to control pasture utilisation and milk production per cow. The aim of the present study was to evaluate the long-term effects of daily herbage allowance (DHA) on ...
Different herbage allowances and milk yield in crossbred Holstein x Gir
(UNIV FEDERAL SANTA MARIASANTA MARIA, 2012)
The objective of this study was to evaluate different herbage allowances in stargrass (Cynodon nlemfuensis Vanderyst var. nlemfuensis), on the herbage disappearance rate (HDR) and milk yield in crossbred Holstein x Gir ...
Short-Term Effect of Daily Herbage Allowance Restriction on Pasture Condition and the Performance of Grazing Dairy Cows during Autumn
(2019)
The aim of this study was to evaluate the short-term effects of daily herbage allowance
(DHA, defined as the product of pre-grazing herbage mass and offered area per animal) on pasture conditions and milk production of ...
