description  Grass monoculture, besides being unnatural to goat’s natural eating habits, exhibits low forage production during the dry season, with negative impacts on animal productivity. This research aimed to determine the productive advantages of silvopastoral system arrangements in goat production. A completely randomized design with repeated measurements through time was used. Six treatments were evaluated: kikuyina grass monoculture (Bothriochloa pertusa) and guinea grass monoculture (Panicum maximum cv. Tanzania) as control groups; guacimo (Guazuma ulmifolia) based silvopastoral arrangement; calabash (Crescentia cujete) based silvopastoral arrangement; lead tree (Leucaena leucocephala) based silvopastoral arrangement; and a mixed based silvopastoral arrangement (guacimo, calabash and leucaena). The information was processed with analysis of variance. The results showed increased forage production in silvopastoral arrangements vs. Bothriochloa pertusa monoculture. The greater increase in height (p <0.05) at 9-14 months of age, was obtained with the leucaena silvopastoral arrangement. All silvopastoral arrangements showed forage yield advantages compared to B. pertusa. The higher dry matter production of guinea grass is highlighted. Overall weight gain of the growing goats was low; nevertheless, a differential response between treatments was observed. Silvopastoral arrangements had the highest (p <0.05) weight gain (22.5 to 33.6 g/animal per day) relative to the guinea grass monoculture (13.2 g/animal per day). The growing goats had higher percentages of estrus and pregnancy in the mixed system (66.7%) and those based on guacimo (66.7%) and on lead tree (55.6%).

Se determinaron las ventajas productivas de los arreglos silvopastoriles para sistemas de producción caprinos. Se utilizó un diseño experimental completamente al azar, con medidas repetidas en el tiempo. Se evaluaron seis tratamientos: monocultivo de pasto kikuyina (Bothriochloa pertusa) y monocultivo de pasto guinea (Panicum maximum cv. Tanzania) como testigos; y cuatro arreglos basados en guácimo (Guazuma ulmifolia); totumo (Crescentia cujete); leucaena (Leucaena leucocephala); y mixto (guácimo, totumo, leucaena). Las informaciones obtenidas se sometieron a análisis de varianza. Los resultados revelaron mayor producción de forraje en los arreglos silvopastoriles en relación con el monocultivo de Bothriochloa pertusa. El mayor (p < 0,05) crecimiento en altura, de 9 a 14 meses de edad, correspondió a leucaena. Los arreglos asociados presentaron ventajas en producción de forraje comparado con B. pertusa. Se destaca la más alta producción de materia seca de pasto guinea. La ganancia de peso de las cabras en crecimiento fue baja; sin embargo, se observó una respuesta diferenciada por los tratamientos. Los arreglos silvopastoriles presentaron las mayores (p < 0,05) ganancias de peso (22,5 a 33,6 g/animal al día) en relación con el monocultivo pasto guinea (13,2 g/animal al día). Las cabras en crecimiento presentaron mayores porcentajes de celo en los tratamientos mixto (66,7%), y los basados en guácimo (66,7%) y en leucaena (55,6%). 2013-02-10 2018-11-06T20:41:32Z 2018-11-06T20:41:32Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revista.corpoica.org.co/index.php/revista/article/view/345 10.21930/rcta.vol14_num1_art:345 http://hdl.handle.net/20.500.12324/33923 spa http://revista.corpoica.org.co/index.php/revista/article/view/345/418 http://revista.corpoica.org.co/index.php/revista/article/view/345/460 application/pdf Colombia Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Corpoica Ciencia y Tecnología Agropecuaria; Vol 14 No 1 (2013); 77-89 Corpoica Ciencia y Tecnología Agropecuaria; Vol. 14 Núm. 1 (2013); 77-89 revista Corpoica Ciência e Tecnologia Agropecuária; v. 14 n. 1 (2013); 77-89 2500-5308 0122-8706 10.21930/rcta.vol14-num1
