Techniques described by Marshall et al. (1967) were used in a field trial situated in Ankole Kingdon, Uganda. Twelve Sanga-type steers were fitted with esophageal fistulas and were for sampling a paddock typical of the area. The pasture was also sampled by means of clipping. Twenty four areas of 5 yd2 each were collected and analyzed. In addition samples were collected of the more common individual grass species; some of these were halved and one-half separated into leaves and stems. Average chemical composition of pasture clipping and chemical composition of fistula samples are compared. Results clearly show the possibilities of the use of fistulated animals for the evaluation of pasture and emphasize the inadequacies of the clipping method. |
