Productivity and sustainability of four grazed grass – alfalfa mixtures

Aspects of productivity,morphological characteristics and nutritive value of two native and four introduced cultivars of alfalfa

Lamb performance from grazed grass in 2013

In mid-season prime lamb production it is essential to optimise lamb performance from grazed pasture to minimise costs and so improve margins from sheep production. This is achieved by continuously supplying high feed value herbage for the duration of the grazing season. Feed value is a combination of nutritive value (i.e. digestibility) and intake characteristics (which is a combination of her...

The Manganese Content of Grasses and Alfalfa from Grazed Plots '

The nutritive value of manganese and its occurrence in animal and plant tissue has received considerable attention within the last few years. The literature relating to manganese in plant tissue has been reviewed by Lindow and Peterson (^)^, who reported analyses of 84 samples representing the principal classes of human foods. In a later paper by Skinner and Peterson {12), analyses of 54 feedin...

Estimating legume N2 fixation in grass-clover mixtures of a grazed organic cropping system using two 15N methods

The input of Nitrogen (N) through symbiotic N2 fixation (SNF) in grass-clover mixtures was determined in an organic cropping system for grazing during 3 years. The mixture of perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) was established by undersowing in spring barley (Hordeum vulgare L.) and maintained subsequently for two production years. Dinitrogen fixation w...

Integrating Weed Management Practices to Enhance Productivity of Grazed Pastures

As animal grazing has intensified within Kentucky and the surrounding region problematic weeds such as tall ironweed, spiny amaranth, horsenettle, buttercup, common cocklebur, and thistles have been increasing. These weeds become prominent in pastures because they have spines, thorns, or are unpalatable to animals. Animals selectively graze and avoid these weedy plants and with intensive grazin...
