Abstract

21 Background: Nano-vitamins and minerals are used in animal nutrition to improve 22 performance and health of broiler chickens as a potential alternative to antibiotic 23 growth promoters. Objective: To evaluate the effect of several levels of a dietary 24 nano α-tocopherol acetate plus selenium compound (NTS) on growth, intestinal 25 histomorphometry, carcass traits, and immune status of broiler chickens. 26 Methods: A total of 240 one-day-old Ross 308 chickens were randomly divided 27 into four groups, each one containing three pens (n=20 in each pen). Four doses of 28 nano α-tocopherol acetate and SE (0, 5, 7, and 10 mg/kg) were included in the 29 basal diet for 42 days. Results: The final body weight (BW), cumulative body 30 weight gain (BWG), and final feed conversion ratio (FCR) significantly improved 31 when NTS levels were increased (P<0.05). The carcass traits and weight of 32 internal organs enhanced in the groups fed with 7 and 10 mg/kg NTS. With high 33 doses of NTS significantly increased the immune vaccine titers against Newcastle 34 disease (ND), avian influenza (AI) virus, infectious Bursal disease (IBD), and 35 infectious bronchitis (IB). Moreover, dietary addition of NTS improved some 36 intestinal morphometric properties. Conclusion: Thus, NTS (7 and 10 mg/kg) can 37 be added in poultry rations to improve production, carcass characteristics, and 38 immune status of broilers. Further studies are needed to evaluate NTS residues in 39 meat. 40

饲粮中添加纳米α-生育酚乙酸加硒对肉鸡生产能力、免疫状态、肠道形态和胴体性状的影响

背景:纳米维生素和矿物质作为抗生素生长促进剂的潜在替代品，被用于动物营养，以改善肉鸡的生产性能和健康。目的:研究饲粮中添加不同水平的24纳米α-生育酚醋酸盐加硒复合物(NTS)对肉鸡生长、肠道组织形态、胴体性状和免疫状态的影响。方法:选取1日龄罗斯308鸡240只，随机分为4组27只，每组设3个鸡舍，每个鸡舍20只。29日粮中添加4个剂量的28纳米α-生育酚乙酸酯和SE(0、5、7、10 mg/kg)，试验期42 d。结果:NTS水平的提高显著提高了末重(BW)、累积增重(BWG)和末饲料系数(FCR) (P<0.05)。7和10 mg/kg NTS组胴体性状和32个脏器重量均有显著提高。高剂量的NTS显著提高了新城疫(ND)、禽流感(AI)病毒、传染性法氏囊病(IBD)和传染性支气管炎(IB)的免疫疫苗滴度。此外，饲粮中添加NTS可改善肠道36项形态学指标。结论:饲粮中添加NTS(7和10 mg/kg)可提高肉鸡产量、胴体特性和免疫状态。需要进一步的研究来评估39种肉类中的NTS残留。40

期刊介绍： The editors of Revista Colombiana de Ciencias Pecuarias (RCCP) welcome the submission of original manuscripts on experimental and clinical studies associated with the broad areas of animal sciences and veterinary medicine as they interface with biochemistry, molecular biology, physiology, pharmacology, toxicology, pathology, microbiology, parasitology, immunology and epidemiology. The scope of the journal includes studies of basic and applied research in animal management and production, feeding and nutrition, reproduction, breeding, genetics, animal welfare and behavior; as well as animal production focussed from biotechnology, soil science, agrostology, silvopastoral systems, livestock economics and the environment. The criteria for acceptance of papers submitted for publication are originality, quality and clarity of the content. Each contribution must be based on original, unpublished research that has not been simultaneously submitted to other journals. All papers will be peer reviewed. All authors bear responsibility for ensuring the integrity and quality of their reported research. It is the author''s responsibility to secure permission to use figures or tables that have been published elsewhere. Contributions may be classified as original research, review, rapid communication, clinical case studies or methodological articles, as well as news/commentaries or letters to the editor. Most review articles are invited by the editor. Authors interested in submitting a review article should contact the corresponding editor. Rapid publication of original manuscripts is a goal of the journal. Manuscripts must be written in English. Each manuscript is considered for publication with the understanding that it has not been simultaneously submitted to any other journal. Upon acceptance for publication, papers are subject to editorial review and revision.
