Effects of BSFL on the growth performance of poultry.

References	Breed	Type	Level, %	Age	Performance
[104]	Lohmann Selected Leghorn	DF	50, 100	128 days	No difference in feed intake, egg production, yolk and shell weight. No mortality occurred.
[107]	Laying Hens	FF	10	168 days	No difference in feed intake, BW, liver weight, and the egg-laying rate. No difference in egg yolk weight, egg shell weight, egg shell strength, and Haugh unit. Increases the richness of cecal microbiota.
[106]	Ross 308	DF	5, 10, 15	1–35 days	No difference in FCR (days 1–10). Increases the LW, ADG, DFI and FCR (days 10–35).
[31]	Ross 308	FF	50, 100	21–48 days	No difference in DWG, DFI and FCR.
					No difference in LW, chilled carcass, breast, thighs, abdominal fat, liver, heart and spleen.
[68]	Cobb 500	FF	5, 10, 15	1–79 days	No difference in final weight, DFI and FCR (days 7–28). Increases the final weight (days 28–79). No effects on breast meat weight, abdominal fat content, and internal organ (liver, heart, gizzard, and spleen) weights.
[108]	Ross 308	FF	5	1–39 days	No difference in final weight DFI and FCR. No difference in slaughtering performance.
[105]	Ross 308	FF	50, 75, 100	1–42 days	Reduces the LW of the whole stage. Decreased ADG (days 1–14, days 14–35). Reduces DFI and FCR in the 100% groups. Reduces carcass weight and muscle weight. Increases abdominal fat deposits. Increases carcass fat content and the proportion of viscera to the total weight.
[109]	R71 L	FF	3, 6, 9	3–50 days	No difference in LW, ADG, DFI and FCR. Reduces mortality (from 4.16% to 2.08%).
[110]	Canedins R71 L White	DF	3, 6, 9	3–50 days	No difference in LW, ADG, DFI and FCR. SW, and consequently the HC and CC weights, and abdominal fat showed a quadratic response with the minimum corresponding to the 6% group.

ADG = average daily gain, BW = body weight, CC = chilled carcass, DF = defatted, DFI = daily feed intake, DWG = daily weight gain, FCR = feed conversion ratio, FF = full-fat, HC = hot carcass, LW = live weight, SW = slaughter weight.
