In situ degradability of dry matter and crude protein of pisonay (Erythrina falcata) leaves and petiole
The study aimed to determine the chemical composition and ruminal degradability of dry matter (DM) and crude protein (CP) of Erythrina falcata at 105, 120 and 135 days of regrowth. Leaves and petiole samples were dried and 8 g of dry grounded samples were placed in nylon bags in the rumen of three male goats during 0, 24, 48 and 72 hours. The DM and CP values were 24.4 and 21.4% at 105, 24.8 and 23.2% at 120 and, 27.2 and 24.4% at 105 days respectively. The ruminal degradability of potentially degradable insoluble fraction of DM and CP was 29.6 and 42.9% at 105, 24.3 and 31.4% at 120 and, 14.9 and 24.1% at 135 days, respectively, and the effective degradability of DM and CP was 41.3 and 41.2% at 105, 36.5 and 30.3% at 120 and, 32.3 and 30.5% at 135 days respectively. The study showed a higher protein advantage in goats at 105 days of growth of E. falcata foliage.

El estudio tuvo como objetivo determinar la composición química y la degradabilidad ruminal de la materia seca (MS) y proteína cruda (PC) del pisonay (Erythrina falcata) a los 105, 120 y 135 días de rebrote. Se tomaron muestras de hojas y peciolo, se secaron y se colocaron 8 g de muestra molida por bolsa de nylon en el rumen de tres chivatos machos adultos por 0, 24, 48 y 72 horas. Los valores de MS y PC fueron 24.4 y 21.4% a los 105, 24.8 y 23.2% a los 120 y, 27.2 y 24.4% a los 135 días, respectivamente.

The study aimed to determine the chemical composition and ruminal degradability of dry matter (DM) and crude protein (CP) of Erythrina falcata at 105, 120 and 135 days of regrowth. Leaves and petiole samples were dried and 8 g of dry grounded samples were placed in nylon bags in the rumen of three male goats during 0, 24, 48 and 72 hours. The DM and CP values were 24.4 and 21.4% at 105, 24.8 and 23.2% at 120 and, 27.2 and 24.4% at 105 days respectively. The ruminal degradability of potentially degradable insoluble fraction of DM and CP was 29.6 and 42.9% at 105, 24.3 and 31.4% at 120 and, 14.9 and 24.1% at 135 days, respectively, and the effective degradability of DM and CP was 41.3 and 41.2% at 105, 36.5 and 30.3% at 120 and, 32.3 and 30.5% at 135 days respectively. The study showed a higher protein advantage in goats at 105 days of growth of E. falcata foliage. |
