Effects of herbage mass and herbage allowance on bite mass of grazing dairy cows
Animal Feed Science and Technology, 2021Abstract Dry matter intake (DMI) of herbage is a product of bite rate and bite mass and is a determinant of the performance of grazing ruminants. This research tested the effect of herbage allowance and herbage mass on average bite mass of individual dairy cows grazing perennial ryegrass herbage (Lolium perenne L.).

Effect of herbage mass per unit area and conditioning treatment on herbage drying rate
Grass and Forage Science, 2001The rates of drying of herbage, cut from perennial ryegrass (Lolium perenne L.) – dominant swards and subjected to different treatments, were investigated under field conditions by changes in weight of herbage in wire mesh trays in 1995 and 1996. A series of replicated factorial experiments studied the effects, in different combinations, of intensity ...

The relationship between herbage mass and pasture accumulation rate in winter
New Zealand Journal of Agricultural Research, 1998Abstract Herbage mass of rotationally grazed paddocks was measured by pasture plate meter on Massey No. 4 Dairy Farm in the Manawatu and at Limestone Downs, a sheep and beef property near Port Waikato, in the North Island, New Zealand. Data were collated and pasture accumulation rates calculated.

Factors influencing the accuracy of herbage mass determinations with a capacitance meter
New Zealand Journal of Crop and Horticultural Science, 1983Abstract Pasture herbage mass was determined before and after grazing of grass‐clover and lucerne pastures with a capacitance meter using the ‘paddock mean method’. This proved to be an accurate and efficient technique for estimating herbage mass for both types of pasture either before or after grazing.

Analysis of Herbage Mass and Herbage Accumulation Rate Using Gompertz Equations
Agronomy Journal, 2010Sigmoid equations are recognized as representative of the pattern of herbage accumulation during a growth period; however, the various equations and their variability among locations and during the growing season have not been well described. The objectives of this study were to find the most suitable, four‐parameter sigmoid equations to fit measured ...

The effects of change in herbage mass on rates of herbage growth and senescence in mixed swards
Grass and Forage Science, 1984AbstractA study was conducted to determine the influence of a change in herbage mass on rates of herbage growth (G), senescence (S) and net production of green herbage (NP) in swards of Lolium perenne L., Poa annua L. and Trifolium repens L. under continuous stocking with sheep.

The cage method of sampling vegetation was used to estimate herbage mass and herbage consumed by sheep, grazing a pasture dominated by annual species, near Camawon, Western Australia. Using paired quadrats (2m x lm), one caged and the other open, herbage mass and herbage consumed were measured at five stocking rates on two soil types, on eight ...

Calibration of two techniques for estimating herbage mass
Grass and Forage Science, 1993AbstractTwo non‐destructive techniques for estimating herbage mass (dry matter yield) were evaluated during the growing season of 1988, from April to September. Samples were collected from four sites, with ten observations made on twenty‐five days at each site, giving a total of 612 sample units. Observations were obtained from each unit, either with a

The relative efficiency of three methods of estimating herbage mass in veld
Journal of the Grassland Society of Southern Africa, 1985Reports the results of an investigation conducted to compare three methods of estimating herbage mass in terms of their relative efficiencies when precision obtained per unit effort is required;Three methods of estimating herbage mass were compared in terms of their relative efficiencies when precision obtained per unit effort was taken as criterion ...

AbstractTwo experiments are described in which groups of lactating cows, non‐lactating cattle and weaned calves grazed a sequence of swards varying in maturity and herbage mass under strip grazing management at a daily herbage allowance of 60 g dry matter per kg live weight.
