Nutritional Value of Green Seaweed (Ulva Lactuca) for Broiler Chickens

Abstract
The current work aimed to assess the potential of the green seaweed Ulva lactuca (U. lactuca) as an alternative ingredient in broiler chicken diets. The effect of substituting 1.0 or 3.0% of corn with U. lactuca on performance, carcass characteristics, serum constituents and nutrients retention of broilers from 12 to 33 d of age was evaluated. Three treatments were distributed in a RCBD design: T1 = control diet (0% U. lactuca); T2 = 1.0 % U. lactuca; T3 = 3.0 % U. lactuca. Cumulative feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR) and nutrients retention from 12 to 33 d of age were not affected by treatment (P>0.05). Birds which had received T3 had a higher dressing percentage and breast muscle yield compared to those which had received T1 or T2. Serum total lipid, cholesterol and uric acid concentrations were significantly lower in birds which had received T2 and T3 (P green seaweed (U. lactuca).
