We tested an immunomarking system that used egg white as marker and enzyme-linked immunosorbent assay as a detection assay to characterize face fly (Musca autumnalis DeGeer) dispersal from cow pats in a pastured beef cattle operation. In microcage assays, adult flies acquired marker after contact with cow pats that were treated with marker and field aged up to 11 d. In arena assays on sprayed f...

Abstract The objective was to compare the effects of tall fescue grazing systems utilizing either rotational only or and spring fall stockpiling on beef cow body condition reproductive performance, calf pre-weaning forage characteristics. Over 2 years, multiparous, fall-calving cows (n = 360/year; BW 600 ± 64 kg; gestation 113 8.5 d) were randomly assigned 1 treatments (3 reps/treatment/year); ...

Automatic monitoring of liveweight and weight change is now possible with walk–through weighing systems. Computer–based drafting can incorporate a range of measurements such as pregnancy status, past performance, value–for–wool and value–for–meat to implement decisions on supplementary feeding. The combination of these technologies will provide the option of allocating animals likely to give th...

The only global autonomous system in which quasiresonant processes have been previously described is the seminal example of one atom colliding with a diatom molecule. In this work we describe classical quasiresonances in a different context, the grazing angle atomsurface collisions. While in the first system the actions related to the process correspond to the internal vibro-rotational degrees ...

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...

Development of new tillers in smooth bromegrass is largely determinant, with synchronized elevation and Smooth bromegrass (Bromus inermis Leyss.) is poorly adapted to elongation of new apical meristems above the soil surmanagement-intensive rotational grazing because of slow and limited regrowth potential. In an effort to find existing germplasm with tolerface (Krause and Moser, 1977). Cutting ...

Effective grazing management in Australia’s semi-arid rangelands requires monitoring landscape conditions and identifying sustainable productive practice through understanding the interactions of environmental factors soil health. Challenges include extreme rainfall variability, intensifying drought, inherently nutrient-poor soils. We investigated impacts strategies on function—specifically hea...
