Abstract

Background: Tropical grasses, such as elephant grass, have high moisture content during its ideal phenological state for silage. High moisture content hinders proper preservation and reduces the nutritive value of silage due to secondary fermentation and production of effluents. Adding feed materials with high dry matter content, such as murumuru (Astrocaryum murumuru) meal, is a potential alternative to improve silage yield. Objective: To determine the effects of including murumuru meal (0, 7, 14, 21, and 28%) on the fermentative characteristics, microbiological activity, aerobic stability, and chemical composition of elephant grass silages. Methods: A completely randomized design with five treatments and five replicates was used. Elephant grass was collected at 60 d of age, minced, and homogenized with murumuru meal. The mass was placed in experimental 15-L silos. The silos were collected and analyzed 45 d later. Results: Effluent production decreased (p<0.05) as the proportions of murumuru meal in silage increased. A quadratic effect (p<0.05) was observed on dry matter recovery. An increase (p<0.05) was observed in dry matter content, a decrease (p<0.05) in the neutral detergent fiber content, and an increase (p<0.05) in the non-fibrous carbohydrate content with the inclusion of murumuru meal. Conclusions: Addition of murumuru meal improves chemical composition and does not affect the fermentative characteristics of elephant grass silage, while it reduces effluent losses. Nevertheless, the inclusion of murumuru meal in the elephant grass silage decreased the time of aerobic stability.

象草粉作为象草青贮饲料的添加剂

背景:热带牧草，如象草，在其理想的物候状态下具有较高的水分含量。由于二次发酵和废水的产生，高水分含量阻碍了青贮饲料的适当保存，降低了青贮饲料的营养价值。添加干物质含量高的饲料，如Astrocaryum murumuru粕，是提高青贮产量的潜在替代方案。目的:研究添加草粉(0、7、14、21、28%)对象草青贮发酵特性、微生物活性、有氧稳定性和化学成分的影响。方法:采用完全随机设计，5个处理，5个重复。60日龄采集象草，切碎，用murumuru粉均质。物料放置在15-L的实验筒仓中。45 d后收集筒仓进行分析。结果:随着草粉在青贮饲料中所占比例的增加，废液产量降低(p<0.05)。干物质回收率呈二次效应(p<0.05)。添加草粉后，干物质含量增加(p<0.05)，中性洗涤纤维含量降低(p<0.05)，非纤维性碳水化合物含量增加(p<0.05)。结论:添加草粉改善了象草青贮的化学成分，不影响象草青贮的发酵特性，同时减少了废水损失。然而，在象草青贮饲料中添加草粉可缩短其有氧稳定时间。

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.
