Abstract

Feedlots have emerged as an ideal mitigation option to pursue sustainable and efficient livestock production. This paper aims to elucidate how the establishment and widespread adoption of feedlots have provided solutions to complex problems of food security, animal welfare, and environmental sustainability.An observational cross-sectional study compared fecal egg count per gram (EPG), weight gain, and body condition score (BCS) in feedlot and non-feedlot cattle at high throughput abattoirs. Cattle (n = 120) of different age and sex groups, farms, and breeds were selected from two commercial abattoirs (EA1 and EA2) in the Eastern Cape Province.At EA1, non-feedlot cattle exhibited higher EPG values (323.3±28.9) than feedlot cattle (73.3±13.3), indicating a potentially greater susceptibility to internal parasitic infections. The similar weight gains between feedlot (298.1±4.7) and non-feedlot cattle (287.16±7.79) were attributed to the sufficient natural pasture in the communally raised cattle. However, body condition scores were significantly (P< 0.05) better in feedlot than in non-feedlot cattle. Nonetheless, the feedlot farms of origin had a significant effect (P< 0.05) on the EPG and body condition score values in EA1, with no significant effect in EA2.Moreover, the negative correlation between EPG and body condition scores highlights that as parasite load increases, there might be a subtle tendency for body condition to decrease. These results underscore the importance of feedlots as an effective management strategy to improve animal health and productivity. Further investigations into the factors driving the differences in non-feedlot cattle are needed for informed decision-making in livestock management and abattoir operations.
评估东开普省高产能屠宰场中饲养牛和非饲养牛的体况评分、增重动态和粪蛋计数
饲养场已成为追求可持续高效畜牧生产的理想缓解方案。一项观察性横断面研究比较了高产能屠宰场中饲养场和非饲养场牛的每克粪蛋数(EPG)、增重和体况评分(BCS)。东开普省的两个商业屠宰场(EA1 和 EA2)挑选了不同年龄和性别组别、养殖场和品种的牛(n = 120)。在 EA1,非饲养场牛的 EPG 值(323.3±28.9)高于饲养场牛(73.3±13.3),这表明非饲养场牛可能更容易感染体内寄生虫。饲养场牛(298.1±4.7)和非饲养场牛(287.16±7.79)的增重相似,这归因于公共饲养的牛有充足的天然牧草。然而,饲养场牛的体况评分明显优于非饲养场牛(P< 0.05)。然而,在 EA1 中,原产地饲养场对 EPG 和体况评分值有显著影响(P< 0.05),而在 EA2 中则无显著影响。此外,EPG 和体况评分之间的负相关突出表明,随着寄生虫量的增加,体况可能会出现微妙的下降趋势。这些结果凸显了饲养场作为一种有效的管理策略对改善动物健康和提高生产率的重要性。需要进一步调查造成非饲养场牛差异的因素,以便在牲畜管理和屠宰场运营方面做出明智的决策。
