Twenty four lactating Damascus goats were used in a comparative feeding trial to investigate the effect of replacing clover hay (CH) by dry bean vines (DBV) in their diets on nutrient digestibilities, productive performance and economic efficiency. Does were chosen with an average body weight 40±1.50 kg and 3-4 milk seasons. Goats were divided into four groups (6 animals each). The first group T0 was served as control and fed concentrated feed mixture and clover hay at rate of (50: 50). The tested groups T1, T2, and T3 were fed on rations contained DBV (50, 75 or 100%) as replacement of CH in control ration. Results showed that digestibility and feeding values of most nutrients were significantly higher with T2 and insignificant higher with T1 than those of T3 and control T0. While, insignificant difference in digestibility of CP were observed among the dietary treatments, being the highest in T2. Milk composition, feed intake and most blood parameters did not affected significantly by the tested rations. Actual milk and 4%-FCM yields were significantly higher with T2 and insignificant higher with T1 than those of T3 and T0. Feed conversion was improved with T1 and T2, while, the poorest value was occurred with T3 or T0. Economical efficiency was marked improved in T2 compared with the other treatments. It could concluded that replacing clover hay in the diet of lactating goats by dry bean vines up to 75% could led to significant improvement of digestibility, productive performance of goats and profitability.
