In a metabolism trial study conducted at the Botswana College of Agriculture`s farm, twenty yearling Tswana goat castrates were used to determine the digestibility of diets containing two browse plants namely Terminalia serecia or Boscia albitrunca fed along with Cenchrus ciliaris and wheat bran. The browse plants were obtained from Sebele rangelands which were analyzed for proximate composition and evaluated for in vivo dry matter digestibility using Tswana goats. The animals were divided into five groups the control group and four treatment groups. Control group was offered per animal 800 g of lucerne while the treatment groups were offered; 400 g B. albitrunca, 800 g B. albitrunca, 400 g T. serecia and 800 g T. serecia, respectively. Buffel grass hay was offered at 400 g and 250 g wheat bran per goat for all groups and clean water was available at ad libitum. Percentage crude protein values obtained were 10.4, 6.84, 5.72 and 6.11 for lucerne (Medicago sativa), Cenchrus ciliaris, Terminalia serecia and Boscia albitrunca, respectively. The dry matter digestibility coefficients obtained for the goats were 0.692, 0.545, 0.481, 0.412 and 0.490 for control group, treatments 1, 2, 3 and 4, respectively.
