Temperate grass response to extent and timing of grazing

Canadian Journal of Plant Science, 2014
Alber, N. B., Brink, G. E. and Jackson, R. D. 2014. Temperate grass response to extent and timing of grazing. Can. J. Plant Sci. 94: 827–833. Considerable differences exist among cool-season grass species in their production potential and response to management variables.

The time delay of a solar grazing photon

IEEE Aerospace and Electronic Systems Magazine, 1996
Moving clocks and clocks in a gravitational field slow down, not due to the effects of special relativity nor to the space-time curvature of general relativity, but due only to the principle of equivalence and the conservation of energy. However, some might argue that there has been a further "test" of the effect of gravity on time, namely, the ...

A grazing clock for measurement of time spent grazing by cattle.

African Journal of Range and Forage Science, 1981
To date, time spent grazing has been measured most successfully using an electronic grazing clock. Difficulties experienced with this clock however, were that temperature and stage in the life of the batteries affected the readings. Further, periods of grazing shorter than the units of time registered by the clock could not be recorded.

Timing of supplementation on intake and grazing behavior dairy cows

Tropical Animal Health and Production
The objective was to evaluate the response of New Zealand Holstein cows to concentrate supplementation at contrasting times of the day on herbage intake and ingestive behavior. Two experiments were conducted in winter and spring-summer in a grazing dairy production system of Medicago sativa L. with Dactylis glomerata L. pastures.

Time of daily supplementation for steers grazing dormant intermediate wheatgrass pasture

Journal of Animal Science, 1992
To compare the effects of time of daily protein supplementation on grazing behavior, forage intake, digesta kinetics, ruminal fermentation, and serum hormones and metabolites, 12 ruminally cannulated Holstein steers (449 and 378 kg average initial and final BW, respectively) were allotted to three groups. Treatments consisted of CON = no supplement, AM

Milk quality as affected by grazing time of day in Mediterranean goats

Journal of Dairy Research, 2008
We evaluated the effect of grazing time of day on goat milk chemical composition, renneting properties and milk fatty acid profile in a Mediterranean grazing system. Sixteen lactating Girgentana goats were divided into two experimental groups and housed in individual pens, where they received 500 g/d of barley grain.

Grazing time and pattern of grazing of Friesian cows on a tropical grass-legume pasture

Australian Journal of Experimental Agriculture and Animal Husbandry, 1975
Grazing time and pattern of grazing were recorded for 40 milking Friesian cows grazing a Panicum maximum var. trichoglume-Glycine wightii cv. Tinaroo pasture at stocking rates of 1.3, 1.6, 1.9 and 2.5 cows ha-1. These measurements were taken during summer and winter in a tropical upland environment.

Control of Medusahead (Taeniatherum caput-medusae) Using Timely Sheep Grazing

Invasive Plant Science and Management, 2008
Abstract Medusahead is among the most invasive grasses in the western United States. Selective control of this noxious winter annual grass is difficult in California grasslands, as many other desirable annual grasses and both native and nonnative broadleaf forbs are also important components of the rangeland system.

Effect of cow type and feeding strategy on grazing time in simplified rotational grazing systems

2020
Grazing time (GT) is one component of grass intake and varies with animal and sward characteristics. The objective of this experiment was to describe the effect of breed (Holstein vs Normande) and parity (primiparous vs multiparous) on grazing time within simplified rotational grazing systems.

A hybrid model for simulating grazing herds in real time

Computer Animation and Virtual Worlds, 2019
AbstractComputer simulations of animal groups are usually performed via individual‐based modelling, where simulated animals are designed on the level of individuals. With this approach, developers are able to capture behavioural nuances of real animals. However, modelling each individual as its own entity has the downside of having a high computational
