Continuous, season‐long (May–August) grazing is the most commonly used grazing strategy among tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] belt beef (Bos taurus) producers. However, little information is available regarding the feasibility of managing native warm‐season grass (NWSG) pastures in this region with continuous, season‐long grazing. We compared stand sustainability, beef cattle performance, and pasture production between continuous (CONT), season‐long grazing and heavy‐early (HEAVY), a modified continuous grazing strategy, on mixed‐NWSG pastures. Heavy‐early was designed to match the growth curve of NWSG, with an initial stocking target of 1.25 times the CONT density until 25 June, at which time stocking was reduced to 0.75 times the CONT density. Pastures were mixed big bluestem (Andropogon gerardii Vitman), indiangrass [Sorghastrum nutans (L.) Nash], and little bluestem [Schizachyrium scoparium (Michx.)]. The plant population (plants m⁻²) was similar between treatments, but years differed (P < .001), with a 35% reduction from 2017, the third and final year of grazing, to 2018. Despite the decline in plant density, overall tiller density (tillers m⁻²) increased 14%, indicating that the grazing strategies were likely sustainable. The grazing strategies had similar (P > .05) average daily gain (ADG; kg d⁻¹), animal‐days ha⁻¹, and total gain (kg ha⁻¹). Weaned steer ADG was 0.98 kg d⁻¹ for CONT and 0.89 kg d⁻¹ for HEAVY. Total gain was 379 kg ha⁻¹ for CONT and 334 kg ha⁻¹ for HEAVY. Continuous grazing appears to be an appropriate strategy for managing NWSG pastures in the Fescue Belt.

在羊茅带上连续放牧混合的本地暖季草

在高羊茅（黑麦草（Schreb。）Darbysh。）带牛肉（Bos taurus）中，连续的，整个季节（5月至8月）的放牧是最常用的放牧策略。）的生产者。但是，关于在该地区连续进行整个季节的放牧来管理当地暖季草（NWSG）牧场的可行性的信息很少。我们在混合（NWSG）牧场上比较了连续（CONT），整季放牧和重度早期（HEAVY）（一种改良的连续放牧策略）之间的林分可持续性，肉牛性能和牧场生产。重磅早期旨在适应NWSG的增长曲线，到6月25日之前的初始库存目标为CONT密度的1.25倍，此时库存减少为CONT密度的0.75倍。牧场混合有大蓝茎（Andropogon gerardii Vitman），印度草（Sorghastrum nutans（L.）Nash）和小蓝茎（Schizachyrium scoparium）（Michx）。处理之间的植物种群（植物m ^-2）相似，但年份不同（P <.001），从2017年（放牧的第三年和最后一年）到2018年减少了35％。尽管植物密度下降，整体分density密度（分s m ^-2）增加了14％，表明放牧策略可能可持续。放牧策略的平均日增重（ADG; kg d ^-1），动物日ha ^-1和总增重（kg ha ^-1）相似（P > .05 ）。对于CONT，断奶ste牛ADG为0.98 kg d ^-1；对于HEAVY，断奶ste牛ADG为0.89 kg d ^-1。CONT和334 kg ha的总增产分别为379 kg ha ^-1-1（表示重）。持续放牧似乎是管理羊茅地区新南威尔士州牧场的适当策略。
