Abstract

. The purpose of the present study was to determine the chemical composition and in vitro ruminal fermentation capacity of potato pulp (PP), potato pulp with peel (PPp) and potato peel (Pp), i.e. potato starch by-products. PP and PPp were applied at 5.0, 7.5 and 10.0% (on a dry matter basis) instead of corn flake and barley grain in dairy cow total mixed ration (TMR). The volumes of in vitro total gas and methane production, and metabolisable energy (ME) values of PP and PPp were higher compared to Pp ( P < 0.001). The in vitro true dry matter digestion (tDMd) and in vitro true organic matter digestion (tOMd) values of PP using at 7.5% and 10% rates in TMR were decreased linearly according to that of control TMR value ( P < 0.05). Therefore, the use of potato starch by-products in ruminant diet can be suggested due to the high and rapid fermentation potential, especially of potato pulp without peel. The study showed that PP could be applied at up to 5% and PPp at a level of up to 10% in dairy cattle TMR (on a DM basis). Further in vitro studies should be carried out using dried potato starch by-products.

马铃薯淀粉副产物的瘤胃发酵及营养成分

本研究的目的是测定马铃薯淀粉副产物马铃薯浆（PP）、带皮马铃薯浆（PPp）和马铃薯皮（PP）的化学成分和体外瘤胃发酵能力。在奶牛全混合日粮（TMR）中，以5.0%、7.5%和10.0%（以干物质为基础）的PP和PPp代替玉米片和大麦粒。PP和PPp的体外总产气量和甲烷量以及代谢能（ME）值均高于PP（P＜0.001）。在TMR中使用7.5%和10%的PP的体外真干物质消化（tDMd）和体外真有机物消化（tOMd）值与对照TMR值呈线性下降（P＜0.05）。因此，由于马铃薯淀粉副产物具有高而快速的发酵潜力，特别是无皮马铃薯果肉，因此可以建议在反刍动物日粮中使用马铃薯淀粉副产品。研究表明，在奶牛TMR中（以DM为基础），PP最高可施用5%，PPp最高可施用10%。应使用马铃薯淀粉副产品进行进一步的体外研究。

期刊介绍： Journal of Animal and Feed Sciences (JAFS, J. Anim. Feed Sci.) has been published by the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences in Jabłonna (Poland) since 1991. It is a continuation of the Polish-language journal Roczniki Nauk Rolniczych. Seria B, Zootechniczna published by the Polish Academy of Sciences since 1969. JAFS is an international scientific journal published quarterly, about 40 papers per year including original papers, short communications and occasionally reviews. All papers are peer-reviewed and related to basic and applied researches in the field of animal breeding and genetics, physiology of nutrition, animal feeding, feed technology and food preservation. The journal distinguishes the multidisciplinary nature of physiological and nutritional sciences and so includes papers specialized in all fields connected with animal well-being, including molecular and cell biology and the emerging area of genetics.
