Abstract: This experiment was conducted to determine nutrient composition of rosehip seed and determine the effects of various chemical treatments on its nutritive value for ruminants. Three, 2 years old Awassi rams were incubated with rosehip seed subjected to no treatment, ammonization (4%), urea addition (4%) and NaOH treatment (1.5%). After 72 h incubation, ruminal disappearance and degradation kinetics of nutrients in response to different chemical treatment and treatment duration were analyzed using nonlinear model. Concentrations of DM, CP, NDF, ADF, ADL and crude ash were 95.05, 8.84, 60.00, 51.80, 29.91 and 3.49%, respectively, in untreated rosehip seed. Treatments significantly altered nutrient composition, especially protein content. Effective degradability of DM, CP, NDF and ADF were 29.1, 79.6, 9.3 and 4.8% for untreated rosehip seed; 25.7, 69.6, 1.0 and 6.2% for rosehip seed treated with 4% ammonia; 24.3, 83.4, 4.5 and 3.9% for rosehip seed treated with 4% urea and 1.28, 17.9, -1.3 and -8.6% for rosehip seed treated with 1.5% NaOH, respectively.
