The influence of supplementary protein and phosphorus to Dorper and Merino wethers on native pasture was investigated over a period of one year. The supplements were provided by 2 different methods namely as a lick or at a constant daily…

Voluntary feed intake, digestibility and rumen flow- and fermentation dynamics were studies using sheep. NaOH treated (5 % w/w) wheat straw, washed and. unwashed as well as untreated straw were compared. Results indicated that washing the straw had little effect…

A first order model for predicting voluntary intake was applied to sheep fed roughages differing in quality. Important variables identified in this study were the rumen capacity of the animals, the first order rate constant for fermentation of the diet,…

A trial was carried out at the Vaalharts Agricultural Research Station in which Dorper ewes were run on either Cenchrus ciliaris or Panicum maximum pastures or fed lucerne hay. Three lamb crops were obtained over a 2-year period. Lambs were…

An estimate of the total energy intake of litters until weaning, including both energy obtained in-utero and that derived post-natally from milk consumed, is often required in experiments on growth efficiency. Frequently it is, however, impossible to measure this energy directly…
