Forage production and animal response in soils in the Cesar valley under a recovery process

The 90% of potential agricultural soils in Cesar (Colombia) are affected by varying degrees of impairment, negatively impacting livestock production, which is one of the most important economic activities in the region. The aim of the study was to contribute to the recovery of degraded grasslands, t...

Forage production and animal response in soils in the Cesar valley under a recovery process
description The 90% of potential agricultural soils in Cesar (Colombia) are affected by varying degrees of impairment, negatively impacting livestock production, which is one of the most important economic activities in the region. The aim of the study was to contribute to the recovery of degraded grasslands, to progress in rescuing the productive capacity of the affected areas and to improve the sustainability and competitiveness of beef production in this region, by implementing practices in sustainable land management. In assessing weight gains, a completely randomized design was used with repeated measurements over time and the obtained data was subjected to analysis of variance. Sustainable practices were used consisting of appropriate tillage, green manure (Vigna unguiculata), establishment of vegetationwith grasses and legumes (Bothriochloa pertusa, Leucaena leucocephala and Clitoria ternatea) and rotational grazing. We performed a comparative evaluation of feed production and weight gains in calves. The results revealed an increase in dry matter production per unit area and weight gain/animal/day which increased (P≤0.05) by 44.2% and 46.3%, respectively where sustainable practices were applied compared to the control; the highest (P≤0.05) weight gain / ha was seen in the experimental treatment (230.5 kg ha-1) in relation to the control (145.7 kg ha-1).

El objetivo del estudio fue contribuir con la recuperación de las praderas degradadas, avanzar en el rescate de la capacidad productiva de las áreas afectadas y en el mejoramiento de la sostenibilidad y competitividad de la producción de carne bovina en esta región, mediante la implementación de prácticas sostenibles en el manejo de los suelos. En la evaluación de las ganancias de peso se aplicó un diseño completamente al azar con medidas repetidas en el tiempo y la información obtenida se sometió a análisis de varianza. Se aplicaron prácticas sostenibles consistentes en labranza apropiada, incorporación de abonos verdes (Vigna unguiculata), establecimiento de cobertura vegetal con gramíneas y leguminosas asociadas (Bothriochloa pertusa, Leucaena leucocephala y Clitoria ternatea) y rotación de potreros. Se realizó una evaluación comparativa de la producción de forraje y de las ganancias de peso con terneros de levante. Los resultados revelaron un aumento de la producción de materia seca por unidad de área y de las ganancias de peso/animal/día, las cuales fueron superiores (P≤0,05) en 44,2% y 46,3%, respectivamente, donde se aplicaron prácticas sostenibles comparadas con el testigo; se obtuvo mayor (P≤0,05) ganancia de peso/ha en el tratamiento experimental (230,5 kg ha-1) en relación con el testigo (145,7 kg ha-1).    2019-08-09T19:29:58Z 2019-08-09T19:29:58Z 2012 article Artículo científico http://purl.org/coar/resource_type/c_2df8fbb1 info:eu-repo/semantics/article https://purl.org/redcol/resource_type/ART http://purl.org/coar/version/c_970fb48d4fbd8a85 http://revistacta.agrosavia.co/index.php/revista/article/view/244 10.21930/rcta.vol13_num1_art:244 http://hdl.handle.net/20.500.12324/35127 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa http://revistacta.agrosavia.co/index.php/revista/article/view/244/421 Attribution-NonCommercial-ShareAlike 4.0 International http://creativecommons.org/licenses/by-nc-sa/4.0/ info:eu-repo/semantics/openAccess application/pdf application/pdf ‎‎Corporación colombiana de investigación agropecuaria - AGROSAVIA Bogotá, (Colombia) Revista Ciencia y Tecnología Agropecuaria; Vol 13 No 1 (2012); 89-96
