We assessed the effects of high-intensity and low-frequency (HILF) vs. low-intensity and high-frequency (LIHF) grazing on herbage production and performance of beef cattle grazing sorghum pastures. The experimental design was a complete randomized block with two treatments and four replicates (paddocks), carried out in 2014/15. The management target of 50 and 30 cm for pre- and post-grazing, respectively, a LIHF grazing management strategy oriented to maximize beef cattle herbage intake per unit time, was compared with a HILF grazing management strategy of 80 and 20 cm for pre- and post-grazing, respectively, aiming to maximize herbage accumulation and harvest efficiency. Sixteen Brangus steers of 15-month-old and 265 ± 21 kg of live weight (LW) were randomly distributed to paddocks (experimental units). The LIHF resulted in shorter rest periods when compared with the HILF. The greater leaf lamina mass in LIHF allowed greater sward light interception at post-grazing, resulting in greater total herbage production than HILF (7581 and 4154 kg DM/ha, respectively). The average daily gain (ADG) of steers was greater for the LIHF than for the HILF treatment (0.950 and 0.702 kg/animal, respectively); however, even with a greater stocking rate in the HILF, there was no difference for LW gain per ha, with an average of 4 kg LW/ha/day. Our findings demonstrated that the LIHF strategy that is based on offering to the animals an optimal sward structure to favor the maximum herbage intake rate fosters greater herbage production, harvesting efficiency, and ADG without compromising LW gain per area of beef steers, despite the lower herbage harvested per stocking cycle.

ABSTRACT.- Bitter rot (BR), caused by Colletotrichum spp., is one of the most prevalent fungal diseases of apple worldwide. Some Colletotrichum spp. also causes Glomerella leaf spot (GLS), a disease restricted to a few regions worldwide. Recently, we reported the presence of C. siamense causing BR on low-chill apple cultivars in central Argentina. In further studies we detected the presence of apple leaf spot also associated to Colletotrichum spp. Thus, this study was focused to determine and characterize the Colletotrichum species involved in fruit rot and apple leaf spot diseases in Santa Fe, Argentina. A total of thirty-one isolates were obtained from symptomatic fruits and leaves. Morphological characteristics in combination with multilocus phylogenetic analysis revealed that Colletotrichum siamense is the single species associated with fruit rot and leaf spots on low-chill apples in Santa Fe, Argentina. Although in this study we obtained and characterized isolates of C. siamense from leaf spot, we found remarkable differences with typical GLS indicating that this disease is not present in Argentina until now. These findings will be useful to undertake studies of fungicide sensitivity and to understand the epidemiology of the disease in the region based on identified species. © 2022 Informa UK Limited, trading as Taylor & Francis Group |
