Abstract

Abstract A 42 day trial was carried out at Chinhoyi University of Technology’s Farm to measure growth performance, carcass quality and sensory attributes of meat produced from broilers fed lucerne (Medicago sativa) based diets (MSD). A total of 240 Cobb 500 broilers were used in a completely randomised design. Sixty (60) birds were randomly assigned to one of 4 treatments (0% control, 5%, 10% and 15% MSD). Each treatment had 3 replicates of 20 chicks per pen. The 10% and 15% MSD resulted in increased (P<0.05) cumulative feed intake (CFI) of 1637.20g and 1683.90g respectively. Feed conversion ratio (FCR) was significantly higher (P<0.05) in the 15% MSD at 2.2. Average daily gain (ADG) was significantly lower at 59.90g in the 15% MSD. The highest (P < 0.05) dressed weight (DW) was found in the 5% MSD at 1936.80g. The 15% MSD produced the lowest (P < 0.05) live weight (LW) at 1795.00g. No significant treatment differences were noted amongst broiler portion cuts. The 15% MSD had the heaviest (P<0.05) gizzards (79.30g) and the 5% MSD had the longest (P<0.05) ileum (1968.00mm). No differences (P>0.05) were noted among treatments on aroma intensity, amount of connective tissue, overall flavour intensity and a-typical flavour intensity. Meat from the 15% MSD scored lower (P<0.05) on initial impression of juiciness but did not differ when scored on sustained juiciness. It was concluded that lucerne could be used to formulate broiler diets up to 10% inclusion levels without adversely affecting growth performance and sensory attributes of broilers.
