The experiment was investigated the effects of degradability crude protein on some blood parameters of ruminants, two experiments were conducted for three sources dietary crude protein: Soya, whey protein and urea. First experiment, soya was replaced with whey protein, while second experiment, soya was replaced with urea. Fifteen male lambs were used for each experiment and randomly distributed to five treatments T1, T2, T3, T4 and T5. Concentrated was fed at 3% of body weight as DM basis, while alfalfa was fed ad-libitum. Jugular blood was sampled from lambs after 90 days of experiment before feeding morning. Results of replacing soya with whey protein showed decreased blood protein and cholesterol, while, blood urea was increased and blood glucose had a linear increase with increasing whey protein intake, 45.75, 48.5, 52.5, 66.0 and 89.75 mg/dl for T1, T2, T3, T4 and T5. In second experiment, the results of replacing soya with urea showed decreased blood glucose and cholesterol for 2% urea in contrast with control, while blood urea was increased for 2% urea 36.11 mg/dl in contrast with 22.73mg/dl for control. In concluded, feeding high soluble crude proteins, decreased cholesterol and increased blood urea nitrogen.
