“…Average daily feed intake (ADFI), average daily gain (ADG) and feed conversion ratio (FCR) were calculated as follows: ADFI = total feed intake/experimental days; ADG = (final body weight -initial body weight)/experimental days; FCR = ADFI/ADG. An economic analysis of experimental feed and broiler production was calculated based on the prevailing market price of feed and the body weight of the broilers at the end time of the experiment, as is presented below: feed cost was calculated by multiplying cumulative feed intake throughout the feeding period by dominant prices; because a corn-soybean meal diet is widely used and feed cost accounts for approximately 70-80% of the total cost of raising broilers (17), a coefficient of 75% was used and a fixed cost of all groups was calculated: fixed cost = feed cost of PC (a corn-SBM diet in this study)/0.75 -feed cost of PC; total cost (TC) = feed cost + fixed cost; total revenue (TR) = live body weight × price/kg; net profit (NP) = TR -TC; Economic efficiency (EE) = NP/feed cost (18).…”

“…O último índice é a relação custo-benefício (RCB), calculado pela razão entre a RB e o CT (Equação 10). Quanto mais alto o valor de RCB, maior é a rentabilidade do sistema de produção (ANDRADE et al, 2018;IBRAHIM et al, 2021;QAID et al, 2023).…”
