The effect of stage of regrowth on the physical composition and nutritive value of the various vertical strata of kikuyu (Cenchrus clandestinus) pastures

Autor: D. G. Barber, M. A. Benvenutti, David G. Mayer, Jean V. Savian, Craig Findsen

Publikováno v: Tropical Grasslands-Forrajes Tropicales, Vol 8, Iss 2, Pp 141-146 (2020)

A plot study was conducted at the Gatton Research Dairy, Queensland, Australia, to quantify the effects of 5 regrowth periods (9, 11, 14, 16 and 18 days) and 4 vertical strata on the composition and nutritive value of kikuyu (Cenchrus clandestinus) p

Publikováno v: Animal, Vol 14, Iss 12, Pp 2503-2510 (2020)

An understanding of the processes involved in grazing behaviour is a prerequisite for the design of efficient grassland management systems. The purpose of managing the grazing process is to identify sward structures that can maximize animal forage da

Comparison between a laser sensor and mechanical tools to estimate pasture mass in strata of kikuyu (Pennisetum clandestinum) pastures

Autor: C. Findsen, David G. Mayer, D. G. Barber, M. A. Benvenutti, M.V. Colman, K. A. D. Ison

Publikováno v: Animal Feed Science and Technology. 249:31-36

Pasture meters are typically calibrated to estimate total pasture mass (TPM). Recent studies have shown that animal productivity was driven by the level of utilisation of the top leafy stratum (TLS) rather than the TPM. A study of kikuyu (Pennisetum

Ingestive behaviour and forage intake responses of young and mature steers to the vertical differentiation of sugarcane in pen and grazing studies

Autor: Iain J. Gordon, Dennis P. Poppi, D. R. Pavetti, David G. Mayer, M. A. Benvenutti

Publikováno v: The Journal of Agricultural Science. 155:1677-1688

SUMMARYSugarcane is an important forage resource in sub-tropical and tropical areas as it is used during the winter or dry season when the growth rate of pastures is significantly reduced. The current research study assessed the effect of four vertic

‘Rotatinuous’ stocking: An innovation in grazing management to foster both herbage and animal production

Autor: E. A. N. Schneider, Luis Augusto Martins Caetano, Radael Marinho Tres Schons, P. C. de F. Carvalho, Angel Sánchez Zubieta, Jean Carlos Mezzalira, Jean Victor Savian, E Laca, M. A. Benvenutti

Publikováno v: Livestock Science. 245:104406

‘Rotatinuous’ stocking is a grazing management strategy based on animal behavioural responses to sward structure which is designed to maximize herbage intake per unit of grazing time. It is an alternative to traditional grazing management practic

Defoliation dynamics, pasture intake and milk production of dairy cows grazing lucerne pastures in a partial mixed-ration system

Autor: N. Kleinitz, M. A. Benvenutti, D. G. Barber, David G. Mayer, Dennis P. Poppi, K. A. D. Ison

Publikováno v: Animal Production Science. 60:175

The effect of lucerne pasture allocation on defoliation dynamics, pasture intake and animal production was investigated in a subtropical partial mixed-ration dairy system. The study took place at the Gatton Research Dairy, south-eastern Queensland, w

Applicability of Eddy Covariance to Estimate Methane Emissions from Grazing Cattle

Autor: Thomas K. Flesch, Sean M. McGinn, E. Charmley, Trevor Coates, M. A. Benvenutti, Deli Chen

Publikováno v: Journal of environmental quality. 47(1)

Grazing systems represent a significant source of enteric methane (CH), but available techniques for quantifying herd scale emissions are limited. This study explores the capability of an eddy covariance (EC) measurement system for long-term monitori
