| description | The foliage of some trees can be used for feeding small ruminants, when the chemical quality and the content of secondary metabolites are suitable. The use of Erythrina americana as feed requires knowledge of its nutritional composition at different regrowth ages. The objective of the study was to determine the influence of the regrowth age of E. americana on the content of phenolic compounds and chemical composition of the foliage, from 24 trees that are part of the live fences of a sheep farm. A completely randomized design was used; the fixed factor was the regrowth age of E. americana (60 days, 90 days and 120 days). The response variables were: dry matter, crude protein, ash, organic matter, neutral detergent fiber, acid detergent fiber, total polyphenols, non-tannin phenols, condensed tannins, hydrolysable tannins and total tannins. The regrowth age affected (P < 0.05) the content of crude protein, structural carbohydrates, total polyphenols and tannins (condensed, hydrolysable and total); the rest of the variables was not affected (P> 0.05). At 90 days, the highest crude protein content was detected. The lowest structural carbohydrates content was between 90 days and 120 days. As the regrowth age increased, a higher condensed tannins concentration was detected. Crude protein, condensed tannins and structural carbohydrates in foliage of E. americana, at an age of regrowth of 90 days, allow to consider it as a complementary food for small ruminants. |

El follaje de algunos árboles puede utilizarse en la alimentación de pequeños rumiantes, cuando la calidad química y contenido de metabolitos secundarios son adecuados. El uso de Erythrina americana como alimento, requiere del conocimiento de su composición nutricional a diferentes edades de rebrote. El objetivo del estudio fue determinar la influencia de la edad de rebrote de E. americana en el contenido de compuestos fenólicos y composición química del follaje, a partir de 24 árboles que forman parte de los cercos vivos de una explotación ovina. Se utilizó un diseño completamente al azar, el factor fijo fue la edad de rebrote de E. americana (60 días, 90 días y 120 días). Las variables dependientes fueron: materia seca, proteína cruda, cenizas, materia orgánica, fibra detergente neutro, fibra detergente ácido, polifenoles totales, fenoles no taninos, taninos condensados, taninos hidrolizables y taninos totales. La edad de rebrote afectó (P < 0.05) el contenido de proteína cruda, carbohidratos estructurales, polifenoles totales y taninos (condensados, hidrolizables y totales), el resto de las variables no fueron afectadas (P > 0.05). A los 90 días se detectó el mayor contenido de proteína cruda. El menor contenido de carbohidratos estructurales se presentó entre 90 días y 120 días. Conforme se incrementó la edad de rebrote aumentó la concentración de taninos condensados. Los contenidos de proteína cruda, carbohidratos estructurales y taninos condensados en el follaje de E. americana, a una edad de rebrote de 90 días, permiten considerarlo como alimento complementario para pequeños rumiantes.
