Changes in herbage mass and time of herbage allocation modify nutritional and metabolic status of dairy cows
(2018)
In temperate milk production systems, it is important to study the effect of grazing strategies in both the quantity and quality of the diet, resulting in potential impacts on animal metabolism. The aim was to evaluate the ...
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. ...
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 ...
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. ...
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 ...
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 ...
Herbage Production, Nutritive Value and Grazing Preference of Diploid and Tetraploid Perennial Ryegrass Cultivars (Lolium perenne L.)
(Instituto de Investigaciones Agropecuarias, INIA, 2009)
