Hay quality and intake by dairy cows. 2. Predicting feed intake with consumer-demand models
Autor: S. K. Baker, D. B. Purser, R. J. Sadler
Publikováno v: Animal Production Science. 58:730
Daily food intake is the single most important factor affecting milk production by dairy cows. However, an animal’s choice of food depends not only on the nutritional characteristics of the food in question, but also on the nutritional characterist

Fodder quality and intake by dairy cows. 1. Preference for oaten hays
Autor: Robyn A. Dynes, S. K. Baker, D. B. Purser
Publikováno v: Animal Production Science. 58:719
This work was undertaken to determine whether measurement of preference 30 min after alternative hays are offered to lactating dairy cows adequately predicts preference over a 3-day period and to determine the influence of the concentrations of water

Autor: MJ Barnes, D. B. Purser, DW Peter, DG Masters, SP Roe, C. L. White
Publikováno v: Australian Journal of Agricultural Research. 43:795
The safety and effectiveness of a loose mineral lick containing all known essential elements was investigated in an experiment in which 96 Merino weaner wethers grazed subterranean clover/grass pastures during summer and autumn. The treatments were n

Autor: SP Roe, MJ Barnes, D. B. Purser, C. L. White, DW Peter, DG Masters
Publikováno v: Australian Journal of Agricultural Research. 43:809
Sheep were fed an oaten hayllupin mixture (88: 12 W/W) containing either 0, 1.7, 3.3, 6.3, 12 or 21% of a multi-element mineral mix for 6 months. Each sheep was fed sufficient ration to provide 800 g DM of the oaten hay/lupin mixture per day. The acc

Autor: S. A Rahman, W. J. Tyznik, D. B. Purser
Publikováno v: The Journal of Protozoology. 11:51-55
SYNOPSIS. Factors influencing the cultivation of entodinia in vitro have been studied. It was found that removal of particulate material, culture division, or a combination of both resulted in similar maximum protozoal concentrations. At the same tim
