In trial one, short term intake rate measurements were performed on five wethers with a mean live weight of 41.3 ± 2.5kg. Treatments consisted of whole barley treated with one of five terpenes (α pinene, β pinene, limonene, caryophyllene, and α terpineol) at five concentrations (Omg, 0.001 mg, 0.01 mg, 0.1 mg, and 1.0mg/kg feed). The intake rate of barley was measured during a period of one minute. Each wether was offered sequentially all five terpenes at all concentrations. In trial two long term intake measurements were performed on 12 wethers with a mean live weight of 40.8 ± 1.6kg. Sheep were randomly allocated to 3 treatment groups and one of three terpenes was infused directly into the rumen of four sheep, at a rate of 200mg/day. Measurements of daily intake of lucerne chaff (kg/hd/d) were carried out over a 21 day period. The mean intake rate for whole barley was 136g/min while the mean intake rate per day for lucerne chaff was 1.4 kg/hd/day. The five terpenes tested had no significant effect on either short (P=>0.01) or long term intake.enhttps://researcharchive.lincoln.ac.nz/pages/rightsterpenesintake ratewhole barleyrumen infusionsheeplucerne chaffalfalfaMedicago sativaanimal nutritionpasturesseasonal variationfeed requirementsorganic compoundsDissertationDigital thesis can be viewed by current staff and students of Lincoln University only.
