    Growth and Economic Performance of Improved Indigenous Chicken Fed On Diets Containing Black Soldier Fly (Hermaria Hiucens) Larvae Meal In Kenya
    (Kenyatta University, 2023-03) Mwangi, Kevin Waithaka
    ABSTRACT poultry feed cost constitutes ab o of protein f:‘ed resources, eSPegi\:atllz/of Otf‘total poultry production costs. This is mainly due to the high cost have identified Black soldier fly (, He::f;fl"< concentrates, and their limited availability. Studies elsewhere animal feeds. This study aimed to provid ia 'z‘ IMCEMS') larvae (BSFL) meal as an alternative protein source in and determine the growth and economic e l? ormation on the nutritive value of locally prepared BSFL meal eraded levels of the meal. A total of 3 lspec‘l" Omllance of 1mp}'oved indigenous chicken fed on diets containing study. Five experimental diets were forml;lata }:'1(;' - KALRO Impider ks ol p::ocured i ascd e Ol (C0), 5% (C5), 10% (C10), 15% (C15), and ;O‘V()r tche chick and'grower phases containing BSFL le\fels of 0% (fishmeal and soybean meal). The diet; i % (C20), respectnvf:ly, to replace conventional protein sources for the chick diets and 2550 Kcal/Kg ME redorn:ulated to contain at l'east 2800 Kcal/ Kg ME and 18% CP randomly allocated to the eXperimeugtal and 15% for the growers’ fhets. Tl?e five dietary treatments were Srets from 7to 56 days o T T units in a completely randomized design, and the birds were fed the & od st gabyied o6 ph phase and frm.n. 57 to 126 days for the grower phase. The BSFL meal and o i, Ab et ot proximate composition, and data on body weight and feed intake was collected k y. A ic analysis was done to determine the cost implication of using the BSFL meal in the feeding trial. ;I'he results showgd .that BSFL meal used in the diets had a high CP level at 43.9% and ether ext'ract at 2_9.4 %. There'was a significant difference (P=0.0001) in the feed intake, final body weight, and daily “.velght gain of the chicks at the end of the chick phase. However, in the grower phase, the treatments s{gmf?cantly gffected feed intake, not the final body weight, daily weight gain, and feed conversion ratio. The birds in the dietary treatment CO had the highest final body weight (1673.6:90.70g), and C20 had the lowest final body weight ( 1383.0+86.04g). Dietary treatment €10, whose BSFL meal inclusion was 10%, had the highest final body weight (1564.7+90.70g) among the diets with BSFL meal. Dietary treatments with high inclusion levels of BSFL meal (C15 and C20) resulted in low feed intake and final body weight after the iod, and it gradually feeding trials. The cost of feed consumed was also significantly different for the entire pert reduced with the increase of BSFL meal in the diets. The dietary treatment CO had the highest cost of feed consumed, followed by Cs, C10, C15, and C20, respectively. The treatments also significantly affected the total cost of production, which reduced gradually, with the highest being CO and the lowest being C20. Nonetheless, the control diet CO recorded the highest gross profit margin (27 6.3+42.15 Ksh) in the feeding trials, while C10 recorded the highest gross profit margin (254.3+42.15) among fiie.ts with B.SFI., meal. According to these findings, BSFL meal can replace conventional protein sources it improved \nd{genous erformance. This study chicken diets at certain inclusion levels without affecting their grow
