The phosphorus requirement of pregnant sheep

The Journal of Agricultural Science, 1976
SummaryThirty-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 ...

The maintenance requirement of the adult sheep

The Journal of Agricultural Science, 1926
In 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.

Mineral requirements of hair sheep in tropical climates

Journal of Animal Physiology and Animal Nutrition, 2016
SummaryIn 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, 1962
The 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 ...

Effect of shearing on feed requirements of sheep

New Zealand Journal of Crop and Horticultural Science, 1974
Abstract 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. Subjective observation suggests the increase would be considerably
