Abstract

Background: Soybean milk by-product (SMBP) is a potential alternative feed ingredient in swine diets due to its high protein content. However, information on energy and nutritional values of SMBP used as swine feed ingredient is limited. Objective: To estimate energy values and protein digestibility of SMBP in pigs based on in vitro assays. Methods: Four SMBP samples were obtained from 3 soybean milk-producing facilities. In vitro total tract disappearance (IVTTD) and in vitro ileal disappearance (IVID) of dry matter (DM) in the SMBP samples were determined. In vitro ileal disappearance of crude protein was determined by analyzing crude protein content in undigested residues after determining IVID of DM. Digestible and metabolizable energy of SMBP were estimated using gross energy, IVTTD of DM, and prediction equations. Results: Sample 4 had greater IVTTD of DM than that of sample 3 (97.7 vs. 94.4%, p<0.05), whereas IVID of DM in sample 4 was lower compared with sample 1 (53.5 vs. 65.0%, p<0.05). In vitro ileal disappearance of crude protein in sample 2 was greater than that in sample 1 and 3 (92.6 vs. 90.6 and 90.1%; p<0.05). The estimated metabolizable energy of SMBP ranged from 4,311 to 4,619 kcal/kg as-is basis and the value of sample 3 was the least (p<0.05) among SMBP samples. Conclusion: Energy values and protein digestibility should be determined before using SMBP in swine diets.

猪体外测定豆浆副产物的能量值和蛋白质消化率

背景：豆浆副产物（SMBP）蛋白质含量高，是猪日粮中一种潜在的替代饲料成分。然而，关于用作猪饲料成分的SMBP的能量和营养价值的信息是有限的。目的：通过体外试验测定猪SMBP的能量值和蛋白质消化率。方法：从3个豆浆生产设施中提取4个SMBP样品。测定了SMBP样品中干物质（DM）的体外总道消失（IVTTD）和体外回肠消失（IVID）。在测定DM的IVID后，通过分析未消化残留物中的粗蛋白含量来测定粗蛋白的体外回肠消失。使用总能量、DM的IVTTD和预测方程来估计SMBP的消化能和代谢能。结果：样品4的DM IVTTD大于样品3（97.7%对94.4%，而样品4中DM的IVID与样品1相比较低（53.5 vs.65.0%，p<0.05）。样品2中粗蛋白的体外回肠消失大于样品1和样品3（92.6 vs.90.6和90.1%；p<0.05）。SMBP的估计代谢能范围为4311至4619kcal/kg，样品3的值在SMBP样品中最小（p<0.05）。结论：在猪日粮中使用SMBP之前，应测定能量值和蛋白质消化率。

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.
