El alto contenido de fibra en forrajes tropicales y su reducida digestibilidad por los rumiantes, es uno de los más grandes limitantes para la productividad animal en el trópico. En este artículo la discusión se centra en dos grandes áreas. La primera tiene que ver con el consumo voluntario de rumiantes en pastoreo, factores que lo afectan y estrat...
RESUMEN
En los últimos años, los sistemas silvopastoriles intensivos (SSPi) se han convertido en una alternativa para intensificar naturalmente la ganadería y convertirla en una actividad ambiental y socialmente responsable. Una de los SSPi mejor estudiados y sobre los cuales se han reportado ventajas productivas y ambientales, son aquellos con la...
The operation of wastewater treatment technologies depends on a combination of physical, chemical and biological factors. Microorganisms present in wastewater treatment plants play essential roles in the degradation and removal of organic waste and xenobiotic pollutants. Several microorganisms have been used in complementary treatments to process e...

In Colombia, the beef production chain accounts for approximately 11.6 million cattle heads and annually produces 933 million kg of the beef carcass. There are no life cycle assessment (LCA) studies that have evaluated the environmental performance of Colombian beef systems. The present study aimed to estimate the carbon footprint (CF), non-renewab...
Dual-purpose cattle systems (DPS) include more than 75% of all dairy cows in Latin America and produce 40% of total milk production. Colombia has the fourth largest cattle herd in Latin America, and DPS account for 39% of the cattle population, and 58% of national milk production. Therefore, focusing on reducing the carbon footprint (CF) of DPS can...
The beef production chain in Colombia accounts for approximately 15.5 million cattle heads. Cow-calf and cattle-fattening represent 40.4 and 45.2% of the Colombian beef herd respectively, and the remaining 14.4% corresponds to full-cycle systems. The present study aimed to estimate, based on a farm gate LCA approach, the carbon footprint (CF) of 25...
There are few reports on dual-purpose cattle systems characterization in Latin America and Colombia based on large datasets. This limits our understanding of their dynamics, and the establishment of public policies and government programs to improve their productive performance, promotion and rural development. This study aimed to characterize very...
En Colombia, la cría bovina representa el 15% del inventario ganadero, siendo un eslabón importante en la cadena de producción de carne. La carencia de estudios de caracterización limita la adecuada planificación técnica y ambiental de esta actividad. El objetivo de este estudio fue caracterizar los parámetros técnicos y ambientales de fincas de cr...
In Colombia, cattle-fattening farms account for 20.7% of the Colombian cattle herd and play an important role in terms of economic and social benefits for rural communities. However, few characterization studies have been conducted on these production systems, which limit our understanding of their production dynamics and environmental impacts. Thi...
Carbon Footprint of 192 dairy cattle farms in Colombia by using Life Cycle Assessment Methodology.
En los sistemas de pastoreo extensivo se localiza aproximadamente el 90% del inventario ganadero correspondiente a la cadena de producción de carne en Colombia. Este carácter extensivo sumado al bajo valor nutritivo de las gramíneas tropicales ha generado estancamiento en la cantidad de animales que conforman el
hato nacional y bajos índices de pro...
Background: Removal of organic pollutants in the form of fats, oils and greases is a demanding
procedure in wastewater treatment. Microorganisms present in wastewater play essential roles in
the degradation and removal of these compounds and the analysis of their population structure
and function has become the basis for problem solving and optimiz...
A nivel mundial, la ganadería es responsable del 18 % de las emisiones de gases de efecto de invernadero (GEI) y la deforestación tropical aporta aproximadamente entre un 20 – 25 % de dichas emisiones. En Latinoamérica, la producción ganadera de carne, leche y doble propósito es una de las principales actividades agrícolas con una importante huella...
Introducción: la ganadería genera 18% de las emisiones de gases de efecto de invernadero a nivel mundial. El análisis de ciclo de vida (ACV) es un método óptimo para cuantificar emisiones. Sin embargo, requiere datos confiables y directos de sistemas reales. Objetivo: proponer una aproximación para obtener información de pequeños y medianos product...
La resistencia generada por las garrapatas a los acaricidas es un problema que limita el control de las infestaciones de manera efectiva, aumenta los costos de producción en ganadería, y que tiene implicaciones negativas por el deterioro que ocasionan los agroquímicos sobre el medioambiente y la salud de operarios y consumidores. Los programas de m...
Resumen
El control de garrapatas en sistemas ganaderos a través de sustancias acaricidas convencionales es cada vez menos efectivo debido a la capacidad de estos individuos para desarrollar resistencia. El uso de vacunas y hongos acaropatógenos articulados a programas de manejo integrado de parásitos – MIP, surgen como una alternativa para realizar...
Resumen
El presente estudio se realizó con el propósito de relacionar las cargas de la garrapata Rhipicephalus (Boophilus) microplus en hembras bovinas de diferente raza pastoreando en sistemas silvopastoriles intensivos (SSPi) o en sistemas tradicionales de monocultivo, en los departamentos de Tolima y Valle del Cauca, Colombia. Se realizaron cont...
p> Rhipicephalus (Boophilus) microplus ticks cause significant economic losses to the Colombian cattle sector: reduction in meat and milk production, blood losses and transmission of blood parasites. The degree of infestation depends on the breed, physiological state and nutrition of the animal and on microclimatic characteristics, which affect the...

Dumps are sites where the presence of high heavy metal (HM) concentration is a common occurrence, creating the need for implementing restoration processes immediately after their closure. In the 7.6 ha and 45 m high Morro de Moravia dump, arose from the disposal of Medellín solid wastes from 1974 to 1984, previous studies have demonstrated high con...
Characterization of the species present in a given locality by means of biological inventories provides information about diversity, even if it is done in disturbed environments such as open dumps, which are considered a threat for health due to the accumulation of heavy metals that are well known for their negative effects on human health and the...
Floristic characterization, plant tissue and residue matrix (RM) analysis were conducted to establish the extent of heavy metal (HM) pollution of the Moravia dump at Medellín, Colombia, a site that was inhabited by more than 17000 people since 1984. More than 65 plant species (28 families) were identified, most of which were herbaceous. Content of...

The savannas of the eastern plains of Colombia cover an area of approximately 5.5 million hectares. There are at least 153 documented plant species, which belong to 93 genera and 34 families. Andropogon bicornis L. and Panicum campestre Nees are among the predominant native plant species in the Colombian savanna ecosystem. Dark brown to black asco-...
En los basureros se observan altas concentraciones de metales pesados (MP), creando la necesidad de conducir procesos de restauración en dichos lugares. El Morro de basuras de Moravia es un cerro de 7.6 ha y 45 m de altura, localizado en la zona nororiental de la ciudad de Medellín, en el departamento de Antioquia. El cerro, resultado de la disposi...
