摘要

认识到在关键的断奶前阶段营养策略的重要性,我们的研究重点是补充耶路撒冷洋蓟作为益生元的影响,揭示其促进犊牛最佳生长、瘤胃健康和免疫力的潜力。选取24头平均体重为23.64±0.57 kg的15日龄犊牛,随机分为4组。ⅰ组为对照组(CON),饲喂基础饲粮(犊牛发酵剂和青饲料),不添加任何添加剂。试验组JAP 1、JAP 2和JAP 3分别饲喂在基础饲粮中添加1%、2%和3%水平的菊芋粉(JAP),试验期为60 d。再饲喂60 d,在120 d时对其生长性能、瘤胃发酵、微生物酶和原生动物种群进行评价。此外,急性期蛋白如血清淀粉样蛋白A、触珠蛋白和纤维蛋白原每隔一个月评估一次。结果表明,犊牛在接受JAP后表现出改善(p 0.05),丙酸盐和丁酸盐浓度显著升高(p 0.05),表明犊牛炎症反应平衡。这些发现强调了菊芋块茎作为一种天然益生元的巨大潜力,强调了在关键的断奶前阶段给予菊芋块茎的有效性,战略性地利用瘤胃完全成熟之前的发育窗口,从而促进小牛生长,减少腹泻发生率,促进瘤胃健康并有助于整体健康。

Exploring the Benefits of Jerusalem Artichoke Tubers as a Prebiotic Supplement: Effects on Growth Performance, Rumen Environment and Serum Acute-Phase Proteins in Weaned Crossbred Calves.

Recognizing the critical importance of nutritional strategies during the crucial preweaning phase, our investigation focuses on the impact of supplementing Jerusalem artichoke tubers as a prebiotic, shedding light on its potential to drive optimal growth, rumen health and immunity of calves. Twenty-four 15-day-old calves, with an average body weight of 23.64 ± 0.57 kg, were randomly assigned to four groups. Group I served as the control (CON), receiving the basal diet (calf starter and green fodder) without any supplementation. The experimental groups, namely JAP 1, JAP 2 and JAP 3, received the basal diet supplemented with Jerusalem artichoke powder (JAP) at graded levels of 1%, 2% and 3%, respectively, for 60 days. The feeding trial continued for another 60 days, and we evaluated their growth performance, rumen fermentation, microbial enzymes and protozoa population at 120 days. Further, acute phase proteins like serum amyloid A, haptoglobin and fibrinogen were assessed at monthly intervals. The results demonstrated that calves receiving JAP exhibited improvements (p < 0.05) in weight gain, particularly in the JAP 3 group, indicating enhanced nutrient absorption during this critical preweaning period. Importantly, rumen pH remained stable (p > 0.05), while concentrations of propionate and butyrate increased significantly (p < 0.05). Furthermore, the rise (p < 0.05) in ruminal protease activity indicated enhanced protein degradation without disrupting essential rumen functions, including protozoan populations. Notably, acute phase proteins remained stable (p > 0.05), indicating a balanced inflammatory response. These findings highlight the promising potential of Jerusalem artichoke tuber as a natural prebiotic underscoring its efficacy when administered during the critical preweaning phase, strategically capitalizing on the developmental window before complete rumen maturation, thereby enhancing calf growth, reducing diarrhoea incidence, promoting rumen health and contributing to overall well-being.

期刊介绍: As an international forum for hypothesis-driven scientific research, the Journal of Animal Physiology and Animal Nutrition publishes original papers in the fields of animal physiology, biochemistry and physiology of nutrition, animal nutrition, feed technology and preservation (only when related to animal nutrition). Well-conducted scientific work that meets the technical and ethical standards is considered only on the basis of scientific rigor. Research on farm and companion animals is preferred. Comparative work on exotic species is welcome too. Pharmacological or toxicological experiments with a direct reference to nutrition are also considered. Manuscripts on fish and other aquatic non-mammals with topics on growth or nutrition will not be accepted. Manuscripts may be rejected on the grounds that the subject is too specialized or that the contribution they make to animal physiology and nutrition is insufficient. In addition, reviews on topics of current interest within the scope of the journal are welcome. Authors are advised to send an outline to the Editorial Office for approval prior to submission.
