Contenido : |
La alfalfa es una leguminosa de crecimiento estival con alto potencial de rendimiento y calidad de forraje. La combinación del potencial de crecimiento con la tolerancia a la sequía dado por su sistema radicular le confiere a esta leguminosa un especial y creciente interés por parte de los usuarios. Las diferencias entre cultivares dependen del potencial genético individual, independientemente del grupo de latencia al que pertenezcan. La producción acumulada anual de la alfalfa 2016 no dista mucho del logrado por el Lotus corniculatus L. sembrado el mismo año debido a la ocurrencia de enfermedades, principalmente mildiú en reiteradas ocasiones. Sin embargo, en el ensayo de alfalfa 2017 se evidenciaron producciones promedio acumuladas acordes a las ventajas comparativas de la especie. A continuación se presentan algunas características a considerarse en la elección de las variedades más adecuadas para cada explotación de acuerdo a los objetivos planteados. |

SUMMARY.
The association between residual feed intake (RFI) and growth, carcass and meat quality traits were investigated using 233 Hereford steers. Individual feed intake, body liveweight, average daily gain and ultrasound measurements were recorded during 70-d post-weaning period to calculate RFI. Steers were categorized into high efficient (<0.5 SD below the RFI mean; 72), medium (mid ± 0.5 SD; 85), and low efficient steers (>0.5 SD above the RFI mean; 76). After the feed intake test, steers grazed on sorghum pasture and oat with corn supplementation during summer and autumn and winter, respectively, until achieving the slaughter weight (with back fat thickness 6.35 mm). During the finishing phase, the efficient steers had some lighter weights (P<0.05) at the start of finishing but achieved the same slaughter weight (P<0.001). Average daily gains during finishing were similar among efficiency groups. No differences were found among groups on ultrasound measures except a slight difference on UBFAT at pre-slaughter between medium and lower efficient (P=0.009). No differences were found among RFI groups for any carcass or meat quality traits. Phenotypic correlations with RFI were close to zero for all traits. These results suggest that increasing feed efficiency by RFI does not lead to unfavorable effect on finishing performance, carcass and meat quality. Larger dataset will allow the estimation of genetic correlation among these traits and the prediction of genetic correlated responses. Keywords: Residual feed intake, beef cattle, growth, tenderness.
