摘要:

试验旨在应用康奈尔净碳水化合物—蛋白质体系(CNCPS)和体外产气法评定不同地方苹果渣的营养价值,以采集自辽宁锦州、北京、河北唐山、安徽砀山的4种苹果渣为研究对象,采用CNCPS中碳水化合物和含氮化合物的分类方法,测定苹果渣的营养成分,评定其营养价值,同时采用体外产气法评定苹果渣的发酵情况,并计算其能量价值。结果显示,不同地域来源的苹果渣的营养成分存在显著差异,且CNCPS碳水化合物、蛋白质组分的优劣不同。在含氮化合物组分中,苹果渣的非蛋白氮(PA)含量较高,均高于60%;而快速降解蛋白(PB1)含量较低,均低于3%。在碳水化合物组分中,苹果渣的不可利用的细胞壁(CC)含量较高,为51%~63%。北京苹果渣的最大产气量(B)最高,极显著高于其他3种苹果渣(P<0.01),而唐山苹果渣的产气速度(C)极显著高于北京苹果渣和砀山苹果渣(P<0.01)。砀山苹果渣氨态氮(NH3-N)含量最高,极显著高于其他苹果渣(P<0.01)。不同地方苹果渣瘤胃液挥发性脂肪酸比例差异极显著(P<0.01)。不同地方的苹果渣的总可消化养分(TDN)及其他能值差异较大,以砀山苹果渣的能值最高,极显著高于其他苹果渣(P<0.01)。综上可知,不同地域来源的苹果渣在化学成分、体外瘤胃发酵参数和能量价值方面存在显著差异。本试验在补充中国肉牛常用饲料数据库的同时,也为非粮饲料的开发利用奠定了数据基础,以达到科学合理利用的目的。

Abstract:

The experiment was performed to evaluate the nutritive value of apple pomaces by Cornell net carbohydrate and protein system (CNCPS) and in vitro gas production technique.In these series of researchs,apples pomace collected from Jinzhou (Liaoning province),Tangshan (Hebei province), Dangshan (Anhui province) and Beijing were used as test materials.The nutritive value of apple pomaces was evaluated by CNCPS,the fermentation situation were studied and their energy value was calculated.The results showed that there were significant differences in nutritive components between apple pomaces from different regions.As for the nitrogenous compounds,PA contents of 4 kinds of apple pomaces were all more than 60%,but PB1 contents were all less than 3%.For the carbohydrate compounds,CC contents were high (51% to 62%). The gas production (B) of Beijing apple pomace was the highest which was extremely significantly higher than others (P<0.01). And the gas generation rate (C) of Tangshan apple pomace was extremely significantly higher than Dangshan and Beijing apple pomaces (P<0.01).Dangshan apple pomace had the highest NH3-N content,extremely significantly higher than the others (P<0.01), there were significant difference in VFA among 4 kinds of apple pomaces (P<0.01). TDN and other energy values had obviously difference between apple pomaces from different places which Dangshan apple pomace had the highest energy value,extremely significantly higher than others (P<0.01).In conclusion,the apple pomaces from different regions had significant differences in chemical components and in vitro fermentation parameters. These series of experiments not only supplied the database of beef cattle common feeds but also establishsd the data foundation for the development and utilization of no-grain feeds,carried the point of scientific and reasonable utilization.
