Feeding Value of Fermented Duckweed Meal (Lemna minor Linn.) as a Plant Protein Components in the Formulated Diets of Free- Range Chicken (Gallus gallus domesticus Linn.)

Abstract

The present study evaluates the growth performance and hematological attribute of experimental free-range chicken, Gallus gallus domesticus Linn. (Black Australorp x Barred Plymouth Rock) fed formulated diets of fermented and non-fermented duckweed meal (Lemna minor Linn.). Three isonitrogenous formulated treatment diets are prepared: 0% duckweed (control), 10% Fermented Duckweed Meal (FDM), and 10% Duckweed Meal (DM) inclusions. Five chickens (mean weight = 202.5 g) per replicate are used in a three-month feeding trial under single factorial experiment. Chickens fed FDM diet have significantly (P < 0.05) higher mean final weight (1,182.8 ± 42.13 g) as compared to those fed DM diet (1,070.4 ± 84.61 g). The mean final weight of control and FDM is significantly homogenous (P > 0.05). Variation in feed conversion ratio among treatments is significant, with the highest mean value being observed in DM (5.85 ± 0.52). The average daily gain in weight is higher in DM and is comparable with the control (P > 0.05). Treatment diets have no significant effect on the observed hematological variables.

“…Los niveles de PC determinados en estas plantas acuáticas (Tabla 2) respaldan su posibilidad como fuente de proteína vegetal, que podría reemplazar parcialmente las harinas de soya y de pescado en las dietas de peces y crustáceos (10,11,15). En cuanto a los niveles de cenizas en el JA y la LA, fueron superiores al 14% y no mostraron diferencia significativa (p>0,05) entre ellos (Tabla 2).…”

“…El contenido de vitamina E (26.60 mg/100 g) y ácido ascórbico (3.80 mg/100 g), en la composición mineral destacan el potasio y el magnesio, seguidos del sodio y el cobre (6,8). La lenteja de agua se ha utilizado como proteína vegetal para la producción animal (9,10,11).…”
