PSIV-A-9 Effects of forage composition in a rotational grazing system on the performance of lactating ewes and their lambs

Journal of Animal Science
The objective was to compare the effects of two forage mixes on the performance of lactating ewes and their lambs in a rotational pasture system. Commercial sheep operations are less common in the Midwest, but they can be an efficient use of limited ...

The effects of livestock grazing on biodiversity are multi-trophic: a meta-analysis.

Ecology Letters, 2020
Anthropogenic disturbance has generated a significant loss of biodiversity worldwide and grazing by domestic herbivores is a contributing disturbance. Although the effects of grazing on plants are commonly explored, here we address the potential multi ...

Creep-grazing fall-born calves on winter annual forages

Translational Animal Science
Providing calves with access to high-quality forage through creep grazing prior to weaning may help improve calf productivity. In this study of fall-calving herds, the productivity of a rotationally stocked forage system with 10% of the pasture area ...

416 Implementation of virtual fencing in heifers for mountain summer grazing

Journal of Animal Science
A virtual fencing (VF) system is based on a smartphone application that defines an invisible grazing boundary based on global positioning. Animals are tracked via GPS collars. When reaching the virtual boundary, the collar emits an ascending audio tone,

Determination of gas flux of growing steers under intensive grazing conditions

Translational Animal Science
Ruminants produce one-third of the anthropogenic methane (CH4) emissions worldwide, and 47% of the CH4 emissions result from ruminants under grazing conditions.

395 The effect of forage allocation on steer performance when grazing cereal rye

Journal of Animal Science
With good winter tolerance and rapid spring growth, cereal rye can fill the early spring grazing gap in pasture productivity. However, there are little data regarding how to best use these acres in the Midwest.

184. Differences in Forage Quality and Hematological Parameters of Kiko Goats Grazing Southern Pine Silvopasture and Open Pasture During Summer

Journal of Animal Science
Milder climatic conditions in silvopasture may impact understory vegetation and grazing animals differently than open pasture. However, not much is known about the potential differences in forages and grazing animals because of pasture system.
