Abstract

Abstract This experiment evaluated the effects of sugarcane extract (SCE) on growing pigs' diarrhea incidence, serum immunity, intestinal morphology, and antioxidant enzyme activity. A total of 116 52-day-old commercial pigs (Duroc × Landrace × Jiaxing Black, average weight of 11 ± 1 kg) were randomly allocated to control (CON, basal diet) and 1% SCE group (SCEG, basal diet + 1% SCE). The experiment lasted four weeks. Compared with CON, diarrhea incidence (SCEG: 74.11% versus CON: 54.76%) and diarrhea index (SCEG: 83.65% versus CON: 73.61%) dropped largely in pigs supplemented with SCE. Villus height in the duodenum (p < 0.01) and the ratio of villus height to crypt depth (p < 0.05) increased in SCEG. Dietary SCE enhanced the activity of catalase (CAT) capacity, and decreased tumor necrosis factor α, and malondialdehyde levels in serum (p < 0.05). CAT activity in the ileum increased (p < 0.05) in piglets supplemented with SCE. Thus, dietary supplementation with SCE improved diarrhea incidence, serum antioxidant capacity and immunity, and intestinal villus morphology and may be used as an efficient antibiotic alternative in weaned piglet feed.

甘蔗提取物对生长仔猪生长发育及腹泻的影响

摘要本试验旨在研究甘蔗提取物(SCE)对生长猪腹泻发生率、血清免疫、肠道形态和抗氧化酶活性的影响。试验选用平均体重为11±1 kg的52日龄商品猪(杜×长×嘉兴黑)116头，随机分为对照组(CON，基础日粮)和1% SCE组(SCEG，基础日粮+ 1% SCE)。实验持续了四周。与CON相比，添加SCE的猪腹泻发生率(SCEG: 74.11%， CON: 54.76%)和腹泻指数(SCEG: 83.65%， CON: 73.61%)均显著降低。SCEG组十二指肠绒毛高度(p < 0.01)和绒毛高度与隐窝深度之比(p < 0.05)升高。饲粮SCE提高了血清过氧化氢酶(CAT)活性，降低了血清肿瘤坏死因子α和丙二醛水平(p < 0.05)。添加SCE的仔猪回肠CAT活性显著提高(p < 0.05)。由此可见，饲粮中添加SCE可改善断奶仔猪腹泻发生率、血清抗氧化能力和免疫力，改善肠道绒毛形态，可作为一种有效的抗生素替代品。

期刊介绍： Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
