EXST7015 Daily Design 8 Carefully read the description of the experiment below. Be prepared to answer the questions that follow the design description as a class quiz. In order to study the effect of cutting management on quality of sweet potato (SP) used as forage for dry season feeding of sheep, SP vines were subjected to four cutting regimes: pruning at 4, 6, 8 weeks interval and uncut plots. Cut forages were fed to twelve mature West African dwarf (WAD) sheep confined in individual metabolic pens for 14 days to determine the digestibility. Freshly harvested forage from the plots was chopped, sun dried and stored for the digestibility trial. Although originally grown in 3 separate plots, a single composite sample for each cutting interval was used in the feeding experiment. Twelve male one-year-old WAD sheep were used to estimate the digestibility of sweet potato forage cut at the different intervals. Sheep were placed in individual pens with floors adapted for faecal collection. Each sheep/pen was then randomly assigned to one of the cutting interval forage diets
