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.

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 ...

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.

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.

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.

Incentives, time use and BMI: The roles of eating, grazing and goods

Economics & Human Biology, 2010
In the 2006-2007 American Time Use Survey and its Eating and Health Module over half of adults report grazing (secondary eating/drinking) on a typical day, with grazing time almost equaling primary eating/drinking time. An economic model predicts that higher wage rates (price of time) will lead to substitution of grazing for primary eating/drinking ...

PTZ camera tuning for real time monitoring of cows in grazing fields

2020 IEEE 11th Latin American Symposium on Circuits & Systems (LASCAS), 2020
This article describes a system for automatic monitoring of cattle behavior using video cameras in grazing fields (80 [has]). This system is made up of an IoT cow’s collar in charge of locally store signals obtained from inertial movements units and microphones.

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

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 herbage allocation in strip grazing: Effects on grazing pattern and performance of beef heifers.

Journal of animal science, 2006
The timing of grazing bouts (GB) determines how cattle allot time to meet their nutritional needs. Net photosynthesis and evapotranspirational losses increase herbage nonstructural carbohydrate and DM concentrations, which may lead to longer and more intense GB at dusk.

Effect of stress and time for recovery on the amount of compensatory growth after grazing

Oecologia, 1991
We tested the hypothesis that the amount of compensatory growth after defoliation is affected by the level of stress at which plants grow when defoliated and by the length of time for recovery. Growth response to defoliation went from partial compensation when plants were growing at high relative growth rates (RGR) to overcompensation when plants were ...
