An analysis is presented of the relationships between the form of grazing land or pasture—a form that is expressed by its architecture in the ecosystem—and the dynamics of discharge in the pasture used by cattle. The objective of searching and demonstrating relationships of this nature is to esta...

Tradicionalmente, la investigación en producción animal ha tenido como objetivo un sistema biológico compuesto por el animal y el ambiente en donde vive y crece. Más recientemente, se ha reconocido que se trata de un sistema bioeconómico, con importantes interrelaciones entre los aspectos biológi...

A stem gall nematode is reported for the first time on the promising tropical pasture legume Desmodium ovalifolium CIAT 350 in Colombia. Stem galling was usually associated with damage caused by animal trampling. The nematode has been identified as a new genus of the family Anguinidae.

A grazing trial was carried out in the Eastern Plains of Colombia to compare legume selection by transiently grazed oesophageal-fistulated steers and non-fistulated steers permanently grazing pastures. The 6 pasture types investigated were Arachis pintoi-Brachiaria humidicola mixtures which diffe...

Two experiments were conducted in the neotropical savannas of Carimagua, Colombia to test the hypothesis that Brahman females subjected to sustained grazing undernutrition as heifers can attain high reproductive performance as mature cows if allowed to make compensatory gains. In Experiment 1, we...

A small-plot grazing trial was conducted to assess selection by oesophageal-fistulated steers of 5 shrubby legumes adapted to acid, low-fertility soils (Centrosema arenarium, Desmodium strigillosum, D. velutinum, Flemingia macrophylla, and Tadehagi triquetrum) and the herbaceous Centrosema acutif...

The yield attributes of 18 accessions of Centrosema, comprising the species, C. macrocarpum, C. brasilianum, Centrosema sp. nov. were compared in two experiments under a cutting regime. Small, grazed swards of various Centrosema spp. sown with Andropogon gayanus in mixture were also studied, with...
