This experiment was conducted to determine the effect of date palm leaves (DPL) feeding on the blood parameter of Saanen dairy goat. Nine lactating dairy goats were randomly assigned to treatment in a 3 × 3 Latin squares design. All goats were given a TMR composed of 40% forage and 60% concentrate (corn grain 26%, cotton seed meal 15%, sugar beet pulp 15.5, wheat bran 2%, limestone 0.5%, premix 0.5%, salt 0.5%). The dietary treatment were 1) alfalfa hay (20%), wheat straw (20%) 2) alfalfa hay (20%), DPL (20%) and 3) alfalfa hay (20%), treated (4% urea) and ensiled DPL (20% DM basis). The experiment lasted for 63 d (3 periods of 21 d which 15 d for diet adaptation and last 7 d for data collection). Goats were individually fed twice daily at 07:00 and 15:00. Data were analyzed using General Linear Models procedure of SAS 9.1 for ANOVA to evaluate difference among experimental groups, mean compared with Duncan test. Average dry matter intake by the goats in different treatment were 2055, 2055, and 1794 g/d, respectively. The difference between there means was significant (P < 0.05). Ruminal pH (6.43, 6.41, 6.24); ruminal NH3 (23.8, 22.9, 19.00 mg/100 mL); blood urea nitrogen (20.2, 20.2, 18.9 mg/dL); blood glucose (39.1, 38.5, 40.1 mg/dL); blood Cholesterol (79.7, 79.7, 79.1 mg/dL) were into the normal ranges. Although no differences were detected between these figures, the obtained data on blood triglyceride (6.9, 12.2, 9.9 mg/dL) differed significantly. The studied parameters in this experiment support inclusion of DPL into the diets for dairy goats in a dry area with poor vegetation and rainfall.
