Evaluation of Westwood Larva (Cirina forda) Meal as feed for Broiler Production | Evaluation of Westwood Larva (Cirina forda) Meal as feed for Broiler Production

Bulgarian. One hundred and ninety eight (198) day old broiler chicks of Arbor Acre strain were used todetermine the performance, nutrients digestibility, serum enzymes and organoleptic properties ofbroiler chickens fed graded levels of Westwood larva meal (WLM) as a replacement for local fishmeal(Schilbe mystus) and imported fishmeal. Six experimental diets were fed in a completely randomizeddesign. Diet without fishmeal served as Negative Control (NC). Diet containing 100% importedfishmeal (IF) was the Positive Control (PC). Westwood larva meal replaced imported fishmeal as wellas Schilbe mystus fishmeal (SMF) at 50% and 100% in the other four diets. Data were collected onperformance, serum enzymes and organoleptic properties. Data were analyzed using one-way analysisof variance. The WLM, IF and SMF respectively contained 42.7%, 60.9% and 54.6% crude protein.Westwood Larva meal showed high lysine (7.05%) and low methionine (0.91%) content. The finalbody weight (FBW) and average daily gain (ADG) of broiler chicken fed 50% WLM as replacementfor SMF were significantly higher than those fed 100% SMF. Feeding 100% WLM to broiler chickencaused elevated level of serum alanine aminotransferase (ALT). Highest ether extract, crude fibreand nitrogen-free extract digestibility were noticed in broilers fed 100% SMF, 100% WLM and NC,respectively. Thigh meat of broilers fed diet 100% WLM (T6) had the best colour, flavour, juicinessand acceptability than those fed other diets.It is concluded that WLM could optimally replace SMF and IF in broilers diet at 50% to supportmaximum growth rate.
