Within the context of sustainable intensification of extensive livestock production systems, the inclusion of reduced areas of high productivity combined with strategic supplementation would allow an animal production increase. Sudangrass and direct grazing sorghum appear as alternatives because of their agroecological adaptation and high forage production. To evaluate the effect of these forage basis combined with the use of protein supplementation on average daily gain (ADG) and live weight (LW), 40 Hereford yearling steers (LW, Year 1 = 287 ± 35 kg; Year 2 = 271 ± 19 kg) were used in a random 2 x 2 factorial design for two years, where forage basis (sudangrass ? Sd ? or BMR sorghum ? Sg) and supplementation (0.8% LW with sunflower expeller: with ? S ? or without ? NOS) were evaluated. The animals were randomly allocated to 4 treatments with two replicates: SdNOS, SdS, SgNOS, and SgS. Average daily gain was significantly affected by forage basis and supplementation (Sd = 0.833 vs. Sg = 0.899 kg animal-1 d-1, P < 0.05; NOS = 0.739 kg animal-1 d-1 vs. S = 0.992 kg animal-1 d-1, P < 0.01), as was final LW (Sd = 342.3 vs. Sd = 347.1 kg, P < 0.05; NOS = 334.7 kg vs. S =354.7 kg; P < 0.01). The use of forage sorghums combined with strategic supplementation improved the rearing of steers during summer // RESUMEN: En el marco de una intensificación sostenible de la ganadería extensiva, la inclusión de áreas reducidas de alta productividad combinada con suplementación estratégica permitiría mejorar la productividad animal. El uso de sudangrás o sorgo forrajero es una alternativa dada su mejor adaptación agroecológica a suelos más marginales y alta producción forrajera. Con el objetivo de evaluar el efecto de estas dos bases forrajeras combinadas con suplementación proteica sobre la ganancia media diaria (GMD) y el peso vivo (PV), por dos años, 40 novillos Hereford de sobreaño (PV, Año 1 = 287 ± 35 kg; Año 2 = 271 ± 19 kg) fueron utilizados en un diseño de parcelas al azar con un arreglo factorial de 2 x 2, en donde se evaluó la base forrajera (sudangrás ? Sd ? o sorgo forrajero BMR ? Sg) y la suplementación (0,8% del PV con expeller de girasol: con ?CS? o sin ?SS). Los novillos fueron asignados al azar a 4 tratamientos con dos repeticiones cada uno: SdSS, SdCS, SgSS y SgCS. La GMD fue afectada significativamente por la base forrajera y suplementación (Sd = 0,833 vs. Sg = 0,899 kg animal-1 d-1, P < 0,05; SS = 0,739 kg animal-1 d-1, CS = 0,992 kg animal-1 d -1, P < 0,01), así como el PV final (Sd = 342,3 vs. Sd = 347,1 kg, P < 0,05; SS = 334,7 kg, CS =354,7 kg, P < 0,01). El uso de sorgos forrajeros con suplementación estratégica mejoró la recría estival de novillos.

Abstract: Winterhardiness is a complex trait that involves low temperature tolerance (LTT), vernalization sensitivity, and photoperiod sensitivity. Quantitative trait loci (QTL) for these traits were fi rst identifi ed using biparental mapping populations; candidate genes for all loci have since been identifi ed and characterized. In this research we used a set of 148 accessions consisting of advanced breeding lines from the Oregon barley (Hordeum vulgare L. subsp vulgare) breeding program and selected cultivars that were extensively phenotyped and genotyped with single nucleotide polymorphisms. Using these data for genome-wide association mapping we detected the same QTL and genes that have been systematically characterized using biparental populations over nearly two decades of intensive research. In this sample of germplasm, maximum LTT can be achieved with facultative growth habit, which can be predicted using a three-locus haplotype involving FR-H1, FR-H2, and VRN-H2. The FR-H1and FR-H2 LTT QTL explained 25% of the phenotypic variation, offering the prospect that additional gains from selection can be achieved once favorable alleles are fi xed at these loci. |
