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).

ABSTRACT.- A nodule-inhabiting Paenibacillus sp. strain (UY79) isolated from wild peanut (Arachis villosa) was screened for its antagonistic activity against diverse fungi and oomycetes (Botrytis cinerea, Fusarium verticillioides, Fusarium oxysporum, Fusarium graminearum, Fusarium semitectum, Macrophomina phaseolina, Phomopsis longicolla, Pythium ultimum, Phytophthora sojae, Rhizoctonia solani, Sclerotium rolfsii, and Trichoderma atroviride). The results obtained show that Paenibacillus sp. UY79 was able to antagonize these fungi/oomycetes and that agar-diffusible compounds and volatile compounds (different from HCN) participate in the antagonism exerted. Acetoin, 2, 3-butanediol, and 2-methyl- 1-butanol were identified among the volatile compounds produced by strain UY79 with possible antagonistic activity against fungi/oomycetes. Paenibacillus sp. strain UY79 did not affect symbiotic association or growth promotion of alfalfa plants when coinoculated with rhizobia. By whole-genome sequence analysis, we determined that strain UY79 is a new species of Paenibacillus within the Paenibacillus polymyxa complex. Diverse genes putatively involved in biocontrol activity were identified in the UY79 genome. Furthermore, according to genome mining and antibiosis assays, strain UY79 would have the capability to modulate the growth of bacteria commonly found in soil/plant communities.
