Autor: Rodney A. Hill, D. J. Reid, M. M. Reich, R. E. Hendricksen, R.F. Roberton, C. Gazzola
Publikováno v: Animal Science. 76:471-480
An experiment was conducted to determine if molasses could be successfully used to administer dotriacontane (C32) and hexatriacontane (C36) n-alkane markers to steers and to compare this method with a commercially available intra-ruminal controlled r

Publikováno v: Animal Science. 74:567-577
The n-alkane method was developed in temperate areas as a tool to estimate voluntary intake (VI) at pasture. The present study aimed to investigate the performance of n-alkanes as markers for estimating VI of steers (mean live weight 213 kg) offered

The phosphorus requirements of growing cattle consuming forage diets
Autor: D. B. Coates, R. E. Hendricksen, G. Bortolussi, J. H. Ternouth, R. W. McLean
Publikováno v: The Journal of Agricultural Science. 126:503-510
SUMMARYThe results of six experiments on growing cattle weighing 140–480 kg, and with liveweight gains of —0·46 to 1·11 kg/day, were reanalysed to provide estimates of their phosphorus (P) requirements. The 158 data sets were from individually

Publikováno v: Animal Production Science. 50:284
Steer liveweight gains were measured in an extensive grazing study conducted in a Heteropogon contortus (black speargrass) pasture in central Queensland between 1988 and 2001. Treatments included a range of stocking rates in native pastures, legume-o

Impacts of grazing management options on pasture and animal productivity in a Heteropogon contortus (black speargrass) pasture in central Queensland. 3. Diet composition in autumn
Autor: D. J. Myles, D. M. Orr, D. J. Reid, R. E. Hendricksen
Publikováno v: Animal Production Science. 50:276
The diet selected in autumn by steers fistulated at the oesophageous was studied in a subset of treatments in an extensive grazing study conducted in a Heteropogon contortus pasture in central Queensland between 1988 and 2001. These treatments were a

Publikováno v: Australian Journal of Experimental Agriculture. 41:477
A grazing study commenced in 1988 at Calliope, Central Queensland, measured the effects of stocking rate, legume over-sowing and animal diet supplements/burning on pasture and animal production in a native black speargrass (Heteropogon contortus) pas

Publikováno v: The Journal of Agricultural Science. 95:547-554
SUMMARYEating behaviour and the diet selected by cattle progressively defoliating a crop of Lablab purpureus cv. Rongai were measured in three periods each of 12 days. Crop composition during defoliation was recorded.At the beginning of grazing the c

Publikováno v: The Journal of Agricultural Science. 105:9-14
SUMMARYIn a study of the effect of animal species on the threshold particle size leaving the rumen, two grasses cut at two stages of growth and one mature legume were separated into leaf and stem fractions and fed to cattle and sheep. Samples of rume
