The phosphorus requirement of pregnant sheep
The Journal of Agricultural Science, 1976SummaryThirty-eight mature Scottish Blackface sheep were mated at pasture and 32 brought indoors when 3–4 weeks pregnant. Eight were killed at this stage as controls (CI). The remaining 24 were offered a basal hay ration (200 g/head/day) supplemented with a semi-purified diet containing 84 g crude protein/kg and either 1·5 (P1), 2·8 (P2) or 9·3 (P3) g ...

Mineral requirements of hair sheep in tropical climates
Journal of Animal Physiology and Animal Nutrition, 2016SummaryIn this study, we evaluated the requirements of calcium (Ca), phosphorus (P), magnesium (Mg), sodium (Na) and potassium (K) for sheep hair growth. Experimental diets contained different levels of metabolizable energy [ME; 0.96, 1.28, 1.72, 2.18 and 2.62 Mcal/kg of dry matter, (DM), corresponding to 4.23, 5.64, 7.58, 9.61 and 11.55 MJ/kg DM].

The energy requirements of sheep for maintenance and gain. II. Grazing sheep
The Journal of Agricultural Science, 1962The intake of grazing sheep in terms of digestible organic matter, DOM, has been measured by faecal index methods, employing chromic oxide to measure faecal output and faecal nitrogen for digestibility of pasture. A regression equation for the prediction of digestibility from faecal nitrogen (organic matter basis) was developed from several series of ...

The maintenance requirement of the adult sheep
The Journal of Agricultural Science, 1926In attempting to interpret the results of two series of sheep feeding experiments, we have been confronted with the fact that the sum of the accepted figure for maintenance requirement and the allowance for the live weight increase produced does not account for the whole of the ration consumed. Sheep averaging 100 lb.

Estimates of the energy required for maintenance by adult sheep 2. Grazing sheep
Animal Science, 1963SUMMARYThe mean daily digestible organic matter intake (D) of each of 47 adult sheep during a grazing period of mean length 48 days was estimated by the chromium sesquioxide/faecal nitrogen technique. Mean live-weights (W) and mean daily weight gains (G) were also measured.The regression of D on W and G, and the underlying or functional relationship ...

Effect of shearing on feed requirements of sheep
New Zealand Journal of Experimental Agriculture, 1974Abstract A series of experiments was conducted in which the increased feed (energy) requirement due to shearing was estimated from the live-weight loss of shorn sheep relative to unshorn sheep. The estimate represented the mean increase during the month after shearing.

Water requirements of African goats and haired-sheep
The Journal of Agricultural Science, 1971SummaryA number of species of desert-dwelling ungulates (e.g. Grant's gazelle and oryx) can apparently survive desert conditions without drinking. We were interested in finding out whether goats and sheep herded in the arid Northern Frontier Region of Kenya utilized the same physiological strategies for reducing water requirements as the wild ungulates.
