Corresponding author AYANDIRAN T.A e-mail: [email protected] TEL.+2348035327173 ABSTRACT An experiment of eight-week duration was conducted on the cost effectiveness of replacing fish meal with Cirina forda larva as a protein source in the diet formulation of broiler birds. Forty-five day-old chicks of white leghorn breed were divided into three treatment groups namely A,B and C; each group containing 15 birds was further replicated three times with 5 birds per replicate in a completely randomized design. Three diets tagged I,II and III were formulated. Diet I contained, 0% C. forda and 100% fish meal; Diet II contained 30% C. forda and 70% fish meal, while Diet III contained, 70% C. forda and 30% fish meal in that order. When broiler chicks were fed from starter to finisher stages on the three diets, there was no significant difference (P>0.05) in the cost of production of the broiler diets using C. forda larva and the conventional fish meal as sources of protein. However, the cost ofDIETsupplied to the broiler birds with lower content of C. forda ( Diet II) was marginally cheaper than the cost ofDietIIIonsumed by broiler birds with higher content of C. forda (Diet III); an indication that decreasing levels of C. forda incorporation in the diets of broiler birds may lead to lowering costs ofDIETproduction and hence, economically advisable in formulating diets of broiler birds. INTRODUCTION especially poultry (Fajimi et al., 1993; Tewe, 1997). Consequently, the prices of protein concentrates like Poultry as an agricultural enterprise has been groundnut cake, soyabean meal and fish meal suggested as one of the better placed production conventional protein sources have continued systems possessing the potential to contribute to the continue to soar and it is becoming uneconomical to Nigeria GDP and employment opportunities creation use them in poultryDIET(Esonu et al., 2001). The (Oladokun and Johnson, 2012). In Nigeria, poultry need to look for locally available and cheap sources meat and eggs have been suggested as possessing ofDIET Ingredients particularly those that do not great potentials for bridging the protein associated attract competition between humans and livestock health deficiencies as high yielding exotic poultry are has not abated. easily adaptable to our environment and the technology of production is relatively simple with Class Insecta is the most species-rich taxon of all returns on investment appreciably high (Idufueko, animals, not only posting an enormous biodiversity 1984; Madubuike, 1992: Chilima, 2007).

The first ration group tagged I, 1990; Akintola and Oyegoke, 2002; Oyegoke, et al., contained 0% C. forda and 100% fish meal; the 2006). With its proven levels of acceptance in poultry second ration group tagged II, contained 30% C. birds, it is important to investigate the cost effectiveness forda and 70% fish meal; while the third ration group of replacing fish meals with C. forda larva in the diets of taggedIII, contained 70% C. forda and 30% fish broiler birds. meal.
