Durante la pasada primavera y el verano, se han presentado condiciones climáticas que han provocado un abundante crecimiento del forraje en pie, tanto de campo natural como mejoramientos. Este exceso de forraje ha sido difícil de consumir mediante el pastoreo directo con vacunos y ovinos o de controlar por otros medios (rotativa, enfardado, etc., en particular para el Basalto con suelos con presencia importante de afloramientos rocosos). Por otra parte, particularmente en la región norte, producto de la sequía del año pasado, el alto precio del ganado de reposición, la baja producción relativa de ternero, hace que los ganaderos no puedan manejar exclusivamente con la carga animal el exceso de forraje presente. Y aunque el control del exceso de forraje lo hicieran solo a base de un aumento de la carga, ello no necesariamente le daría un sustento productivo y económico a la empresa para los próximos meses, ya que existen una serie de factores biológicos y de mercado que no se pueden controlar en su totalidad, y que pueden aumentar el riesgo empresarial. Por lo tanto, en base a información generada en INIA Tacuarembó, sobre el manejo de diferentes coberturas de forraje de distintas bases forrajeras durante dos años (1996-1997), su valor nutritivo, efecto de la selectividad animal y la potencial respuesta animal, se realizan una serie de recomendaciones técnicas que forman parte de las soluciones tecnológicas que puede tomar un ganadero en la mencionada situación particular que se está presentado en la región.

Abstract:
The objective of the study was to evaluate associations among animal performance and methane emission traits under feedlot conditions and in respiration chambers in Angus cattle bred to vary in residual feed intake (RFI), which is a measure of feed efficiency. Fifty-nine cattle were tested for feedlot RFI, of which 41 had methane production recorded on an ad libitum grain-based ration in the feedlot, 59 on a restricted grain-based ration in respiration chambers, and 57 on a restricted roughage ration in respiration chambers. The cattle became older and heavier as they went through the different phases of the experiment, but their feed intake (expressed as DMI) and daily emission of enteric methane (methane production rate; MPR) did not increase proportionally, as feed offered was restricted in the respiration chamber tests. Methane emissions by individual animals relative to their DMI were calculated as methane yield (MY; MPR/DMI) and as 2 measures of residual methane production (RMP and RMP), which were calculated as the difference between measured MPR and that predicted from feed intake by 2 different equations. Within each test regime, MPR was positively correlated ( = 0.28 to 0.61) with DMI. Phenotypic correlations for MY, RMP, and RMP between the feedlot test and the restricted grain test ( = 0.40 to 0.43) and between the restricted grain test and the restricted roughage test were moderate ( = 0.36 to 0.41) and moderate to strong between the feedlot test and the restricted roughage test ( = 0.54 to 0.58). These results indicate that the rankings of animals for methane production relative to feed consumed are relatively stable over the 3 test phases. Feedlot feed conversion ratio and RFI were not correlated with MPR in the feedlot test and grain-based chamber test but were negatively correlated with MPR in the chamber roughage test ( = -0.31 and -0.37). Both were negatively correlated with MY and RMP in the feedlot test ( = -0.42 to -0.54) and subsequent chamber roughage test ( = -0.27 to -0.49). Midparent estimated breeding values for RFI tended to be negatively correlated with MY and RMP in the feedlot test ( = -0.27 and -0.27) and were negatively correlated with MY, RMP, and RMP in the chamber roughage test ( = -0.33 to -0.36). These results showed that in young growing cattle, lower RFI was associated with higher MY, RMP, and RMP but had no significant association with MPR. MenosAbstract:
