屠猪伤残是宰后常见的普通病变。但在兽医卫生检验中往往不够重视,仅作一般处理疏于仔细检查,尤其对肉质不良或伴发传染病时易造成误诊错判处理不当。对此,笔者从宰后伤残部位、损害程度、剖检病理特征变化检验检测方法、肉质评定与处理等方面作了专题调研,分别作如下论述供学者、专 相似文献

欧美屠宰行业很早就注意到,畜禽屠体在预冷过程中存在较大的水分蒸发损耗。例如,猪白条在预冷期间,若条件不恰当,在开始预冷的24h内,其预冷损耗可达到3%以上。早在20世纪70年代,国外科学家们便对屠体预冷过程中的损耗状况进行研究,他们发现降低预冷环境的温度,增加环境的相对湿度,减小屠体表面的循环风速,都能够有效地减少屠体预冷期间的重量损耗。 相似文献

Data from the physical and chemical dissection analysis of 50 Large White and 50 Hampshire × Large White carcasses, comprising equal numbers of gilts and castrates, slaughtered at 90 kg liveweight, are presented. The right-hand side of each carcass was dissected into lean, fat and bone and the combined tissues were then minced and chemically analysed for moisture, protein, ether extract and ash. Statistical relationships between the two methods of carcass analysis, except those between bone and ash, were not influenced by sex or breed type. Overall regression equations, i.e. ignoring sex and breed type, for the prediction of percentage lean from moisture, protein and ether extract percentages of the carcasses, had residual standard deviations of 1·26, 1·78 and 1·11, respectively, and corresponding values for the prediction of percentage carcass fat were 1·05, 1·68 and 0·74. Residual standard deviations for predicting percentages of moisture and protein in the carcass from percentage lean content were 1·07 and 0·46 and that for the prediction of percentage ether extract from fat percentage of the carcass was 1·20. Corresponding relationships between bone and ash percentages of the carcass were less satisfactory for predictive purposes. 相似文献
