Stems, leaves and flowers remain after Organic matter digestibility (OMD) of basil was extraction of etheric oils from peppermint and the lowest among the tested roughages, while basil. The data about their chemical peppermint showed only slight decrease, composition and utilization by ruminants are compared to meadow hay (basal diet). scarce. FU and FUG decreased in the order of : hay>peppermint>basil. The data about net The study aimed to determine the nutritive content of tested feeds were value of whole plants of peppermint and basil energy supported the results of in vitro The after distillation and their influence on some by gas production. ruminal parameters of sheep. volume of gas produced by basil was similar to that of barley straw, reported by Bluemmel and Digestibility of peppermint and basil was 0rskov (1993, Anim Feed Sci Technol, 40, determined after different in vivo trials with 109-119). No differences between the diets wethers applying 3x3 Latin square design. were found in pH and VFA concentration of Three diets were tested : 900 g dry matter rumen liquor, which were in the range of 6.57 - (DM) meadow hay (H), 450 g DM meadow hay 6.99 and 4.50 - 5.10 mmol/dl, respectively. plus 450 g DM peppermint (P) and 450 g DM Feeding diet B led to the highest proportion of meadow 450 DM basil hay plus g (B). acetic acid (75 %) in the rumen liquor which The chemical composition of feeds, refusals corresponded to the highest crude fiber content and faeces was determined Weende following of basil. The lowest total protozoa number was method. Feed units were calculated from (FU) counted in the rumen liquor of sheep fed measurements and feed units for digestibility diet B - 151 x 103/ml vs 195 - 197 x 103/ml for to the new growth (FUG) - according Bulgarian diets H and P. feed evaluation system (Todorov, 1992, Agric Acad, Sofia, Bg, 186). In vitro gas production In conclusion, the nutritive value of was measured as described by Menke and peppermint Steingass (1988, Anim Res Develop, 28, 7-53). by-product after etheric-oil distillation was lower to the meadow Rumen fluid was analysed for total and slightly compared individual volatile fatty acids (VFA) using hay. Basil by-product had nutritive value steam distillation and gas chromatography, close to barley straw. The tested by-products, respectively. Protozoa were counted using a particularly from peppermint, could be used Fux-Rosental counting chamber. as roughage compound in sheep feeding.
