项目摘要
Highline Manufacturing Ltd. is an equipment developer and manufacturer that has equipment designed to**process forage. Recent advancements to the forage processor include the addition of a chopper to create a more**homogenous particle size of the chopped forage. However, it is not clear what the optimal severity of forage**processing is. Understanding how to best process forage is important for both Highline Manufacturing Ltd. and**beef cattle producers as beef cattle have the ability to use low-quality forage as a feed source to provide**essential nutrients within their diet. However, unprocessed low-quality forage may constrain total feed intake.**When combined with the inherent low nutrient density for low-quality forages and the arising reduced intake,**low quality forages, may not always provide sufficient nutrients to meet the nutrient requirements for beef**cattle. Forage processing may be one strategy to improve both feed intake and digestibility for low quality**forages fed to beef cattle. However, most previous studies have focused on the use of forage shredders that**produce a high proportion of fine particles and a large particle size variation in the processed product.**Producing a wide range in particle size increases the ability for cattle to sort and may override benefits**associated with processing. In contrast, forage chopping following processing results in a general reduction in**particle size and variation in that particle size. This approach has the potential to**improve low-quality forage utilization, improve nutrient supply for beef cattle, and provide an economic**opportunity for beef cattle producers. However, data is lacking on the ideal severity for which forage is**processed. This study will evaluate how the severity of forage processing affects beef cattle responses such that**we can identify how the severity influences cattle responses in effort to optimize forage processing.
Highline Manufacturing Ltd.是一家设备开发商和制造商,拥有专门用于饲料加工的设备。饲料加工机的最新进展包括增加切碎机,以产生更均匀的切碎饲料颗粒尺寸。然而,目前还不清楚什么是最佳的严重程度的饲料 ** 加工。了解如何最好地加工饲料对Highline制造有限公司和 ** 肉牛生产商都很重要,因为肉牛有能力使用低质量的饲料作为饲料来源,在其饮食中提供 ** 必需的营养素。然而,未加工的低质量饲料可能会限制总饲料摄入量。**当结合低品质牧草固有的低营养密度和由此产生的摄入量减少时,** 低品质牧草可能并不总是提供足够的营养来满足肉牛 ** 的营养需求。饲料加工可能是一种策略,以改善饲料的摄入量和消化率低品质 ** 饲料喂养肉牛。然而,大多数以前的研究都集中在使用饲料粉碎机,** 在加工产品中产生高比例的细颗粒和大的颗粒尺寸变化。生产广泛的颗粒大小增加了牛的分类能力,并可能超越与加工相关的好处 **。相比之下,加工后的草料切碎导致 ** 颗粒尺寸的总体减小和该颗粒尺寸的变化。这种方法有可能提高低质量饲料的利用率,改善肉牛的营养供应,并为肉牛生产者提供经济机会。然而,缺乏关于饲料加工的理想严重程度的数据。本研究将评估饲料加工的严重程度如何影响肉牛的反应,以便 ** 我们可以确定严重程度如何影响牛的反应,努力优化饲料加工。
