CASE HISTORY: A herd of Holstein, Jersey, or Holstein-Jersey cross lactating cattle of mixed ages presented with a sudden drop in milk yield in 94/678 cows on 3 October 2014 (Day 0). The herd was located in Gretna in the Derwent Valley (Tasmania, Australia) and had been grazing dryland pasture. CLINICAL FINDINGS: On Day 0 the cows variably showed recumbency, peracute photosensitisation, inflame...

Because of all-weather working ability, sensitivity to biomass and moisture, and high spatial resolution, Synthetic aperture radar (SAR) satellite images can perfectly complement optical images for pasture monitoring. This paper aims to examine the potential of the integration of COnstellation of small Satellites for the Mediterranean basin Observasion (COSMO-SkyMed), Environmental Satellite Ad...

Grevy’s zebra (Equus grevyi) populations declined dramatically in the last decades of the 20 century. Though now stabilising, there has been an estimated 50-68% drop in numbers over the past 18 years (IUCN, 2012). While there are many threats facing the species, the role of parasite burdens in this decline is poorly understood. Lewa Wildlife Conservancy provides ex situ or marginal (transition ...

This paper reviews current production trends for sheep and beef cattle production in New Zealand and gives some insight into the opportunities for improvement. The New Zealand climate favours pasture growth and this is the key to sheep and beef cattle production with over 95% of the diet being grazed pasture or crop. Exports are the focus of the industry with 92% of sheep meat and 82% of beef e...

Infdtration rate and sediment production were measured over a 2-year period on an intensive rotationally grazed pasture. Measurements were taken prior to the movement of livestock onto the pasture, soon after their removal, and approximately midway through the subsequent rest period of each rotation through the system. Midgrass-dominated interspaces were characterized by significantly higher ht...

Thirty-meter resolution Landsat data were used to evaluate the effects of irrigation management in the Wood River Valley, Upper Klamath Basin, Oregon. In an effort to reduce water use and leave more of the water resource in-stream, 4,674 ha of previously flood irrigated pasture was managed as dryland pasture. Ground-based measurements over one irrigated and one unirrigated pasture site were use...

A replicated randomized block trial was conducted to determine the response of Holstein cows rotationally grazing annual ryegrass-Crimson clover pasture to supplemental concentrate. Within each of 2 yr, 16 Holstein cows were assigned to one of four blocks by energy-corrected milk yield, days in milk, and parity. Treatments included one of four levels of concentrate based on the following grain ...

Nomadic pastoralism has thrived in Asia’s rangelands for several millennia by tracking seasonal changes in forage productivity and coping with a harsh climate. This pastoralist lifestyle, however, has come under intense transformations in recent decades due to socio-political and land use changes. One example is of the high-altitude trans-Himalayan rangelands of the Jammu and Kashmir State in n...

Natural grasses in semiarid rangelands constitute an effective protection against soil erosion and degradation, are a source of natural food for livestock and play a critical role in the hydrologic cycle by contributing to the uptake and transpiration of water. However, natural pastures are threatened by land abandonment and the consequent encroachment of shrubs and trees as well as by changing...

One IO-day experiment in autumn 1994 then four lo-day experiments throughout the 1994195 lactation in a complete Latin square investigated the effect of pasture species on yield, composition and total colour of milk from dairy cows. Treatments were Grasslands Kopu white clover (Trifolium repens L.), Yatsyn1 perennial ryegrass (L&urn perenne L.), Grasslands Kahu timothy (Phfeum pratense L.) and ...
