摘要

摘要本研究的目的是比较分析在深窝和板条地板饲养系统中饲养的育肥猪所获得的内脏的物理参数、基本化学成分以及宏观和微量元素含量。该实验涉及80名普瓦夫斯卡育肥者，其中40头猪被关在深窝围栏中（第一组），40头猪在没有铺盖的板条围栏中（第二组）。评估粪便（舌头、肾脏、心脏、肺和肝脏）的重量、物理特性（pH45、pH24、WHC）、化学成分（水、蛋白质、脂肪）和矿物质含量：常量（K、Na、Mg、Ca）和微量元素（Zn、Fe、Mn、Cu）。根据获得的结果，发现住房系统与一些内脏的基本化学成分之间存在关联，即肺中水分（板条地板深部垃圾）的百分比、蛋白质含量（板条地板>深部垃圾和脂肪（板条地板浅部垃圾）；肺：钠（条板地板>深层垃圾）、钾（条板地面深垃圾）和铜（条板土地<深层垃圾）。一般来说，育肥猪的饲养系统会修改所分析内脏的物理参数和化学成分。

Analysis of physical parameters and chemical composition of offal from Puławska fattening pigs raised in deep litter and slatted floor housing systems

Abstract The objective of this study was to comparatively analyse the physical parameters, basic chemical composition and the macro- and microelement content of offal obtained from fattening pigs raised in deep litter and slatted floor housing systems. The experiment involved a group of 80 Puławska fatteners, including 40 pigs kept in deep-litter pens (group I) and 40 pigs in slatted pens without bedding (group II). Offal (tongues, kidneys, hearts, lungs and livers) were evaluated for weight, physical characteristics (pH45, pH24, WHC), chemical composition (water, protein, fat) and the content of minerals: macro- (K, Na, Mg, Ca) and microelements (Zn, Fe, Mn, Cu). Based on the results obtained, associations were found between housing system and basic chemical composition of some offal, i.e. percentage of water (slatted floordeep litter) in lungs, content of protein (slatted floor>deep litter) and fat (slatted floordeep litter); lungs: sodium (slatted floor>deep litter), potassium (slatted floordeep litter) and copper (slatted floor
