Effect of plant growth-promoting rhizobacteria (PGPR) associated to Pennisetum clandestinum in the altiplano cundiboyacenseEfecto de bacterias promotoras de crecimiento vegetal (PGPR) asociadas a Pennisetum clandestinum en el altiplano cundiboyacense
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-01-17)
Pennisetum clandestinum (kikuyo) is a common pasture in the altiplano cundiboyacense silvopastoral systems, which possesses high nutritional value. Therefore, studies to improve the production process in both economic and environmental terms are very important. The role of inoculation with plant growthpromoting bacteria was evaluated on the growth of kikuyu grass. The 4K and 5B strains were identified, through amplification ...
Effect of the renewal technology pasture of Bothriochloa pertusa (L.) A. Camus on meat production in the North Coast of ColombiaEfecto sobre la producción de carne de la aplicación de tecnologías de renovación de praderas de Bothriochloa pertusa (L.) A. Camus en la Costa Norte Colombiana
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-01-17)
One of the factors that significantly limits the competitiveness and sustainability of the livestock sector in the Caribbean region is the degradation of soils and pastures. The objective of this study was to assess, on farms engaged in the production of meat in the Atlántico department, the effect of pasture renewal technologies, such as mechanical intervention with vertical tillage, establishment of a new grass, ...
Effects of environmental conditions on feeding behavior in beef cattle in an intensive system in the Sinú ValleyEfectos de las condiciones ambientales sobre el comportamiento ingestivo en bovinos de carne en un sistema intensivo en el Valle del Sinú
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2013-01-17)
Increases in temperature and relative humidity together with the solar radiation effect are detrimental to animal welfare, affecting their behavior when it comes to feeding and digestive behavior, which affects their productivity. Therefore, the goal of this research was to analyze the link between atmospheric variables, air temperature, relative humidity, wind speed and solar radiation to the time of grazing and ...
Forage production and animal response in soils in the Cesar valley under a recovery processProducción de forraje y respuesta animal en suelos del valle del Cesar en proceso de recuperación
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
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 ...
Genetic variability in commercial subpopulations of creole colombian breed RomosinuanoVariabilidad genética en subpoblaciones comerciales de la raza criolla colombiana Romosinuano
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
Genetic variability is of great importance when analyzing the conservation of genetic resources and also constitutes the basis for the process of genetic selection and improvement. The main objective of this study was to determine the genetic variability of the Colombian breed Romosinuano through molecular techniques. This study used 12 microsatellite markers to determine the genetic diversity and population structure ...
Use of tropical forage diversity in paired combinations of woody plants as an indicator of preference for inclusion in the design of silvopastoral systems in dry zonesUso de la diversidad forrajera tropical en combinaciones pareadas de leñosas forrajeras como indicador de preferencia para su inclusión en el diseño de sistemas silvopastoriles en zonas secas
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
The effects of climate change on bovine feed availability in dry areas is a major constraint; as an innovation ten woody forages were selected in the dry zone of Rivas (Nicaragua), within which there are functional differences (nutritional, physical and phenological), that show the variability among the woody ones, such as leguminous without thorns (Albizia niopoides, Gliricidia sepium, Leucaena leucocephala, Samanea ...
Forage yield of cutting grass and effect on compositional quality and yield of milk in a dry CaribbeanRendimiento de forraje de gramíneas de corte y efecto sobre calidad composicional y producción de leche en el Caribe seco
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2012-06-08)
Seasonal climates affect the supply of nutrients in livestock systems. In search of different strategies for feeding livestock, we evaluated the effect of nitrogen fertilization of four cut grasses on yield and feed quality in dual purpose cows in Valle del Cesar. Two phases were developed, the first was the assessment of the performance and quality of feed, where the data were analyzed by a randomized block design ...
Methodology for the disinfection and germination of spores and fragments of roots inoculated with Glomus sp. (GEV02) for use under in vitro conditionsMetodología para la desinfección y germinación de esporas y fragmentos de raíces micorrizados con Glomus sp. (GEV02) para su uso bajo condiciones in vitro
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2011-11-23)
Surface disinfection and germination of propagules, used in inoculants based on arbuscular mycorrhizal fungi (AMF), are a requirement of utmost importance for the successful establishment of symbiosis under in vitro conditions. This study assessed a protocol to establish a method of disinfection and germination of spores and root fragments with vesicles of the AMF Glomus sp. (GEV02) under in vitro conditions. The Glomus ...
Diurnal ingestive behavior of beef cattle on Guinea grass (Panicum maximum cv. Mombasa)Comportamiento ingestivo diurno de bovinos de ceba en praderas del pasto Guinea (Panicum maximum cv. Mombasa
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2011-11-23)
The objective of this study was to evaluate the effect of stocking rate on the diurnal feeding behavior and productive performance of fattening steers. The research was carried out over 107 days, from July until October 2010, at the Turipaná research center of Corpoica (Cereté, Colombia). Beef cattle commercial zebu with an average weight of 314 ± 29 kg grazed in a pasture of Guinea cv. Mombasa (Panicum maximum) grass. ...
Effect of nitrogen fertilization on nitrous oxide and methane dynamics in Brachiaria humidicola (Rendle) SchweickerdtEfecto de la fertilización nitrogenada en la dinámica del óxido nitroso y metano en Brachiaria humidicola (Rendle) Schweickerdt.
