3 feeding trials were carried out in which dried and decanted solids from pig faeces were used in varying proportions. A total of 55 fattening bulls were slaughtered at the end of the trial period. Additionally, a number of characteristic data on ruminal physiology were determined in these trials. The molar proportions of acetate and propionate found with the feeding of rations containing faecal solids were intermediate between those observed in concentrate feeding and those established with the feeding of commercial food pellets containing 40% or 50% straw. Slight increases in the molar proportion of butyrate were noticed when rations were fed containing faecal solids. Nonfasted animals fed rations containing a higher proportion of coarse fodder had a significantly lower slauglitered bady mass (0; 50% straw; 25% straw + 25% faecal solids; 50% faecal solids: 55.7%; 51.9%; 51.1%; or 52.2% of the final fattening weight). They developed a lower proportion of flesh and contained a higher proportion of digesta in the stomach and intestines (11.4%; 18.4%; 17.0%; or 16.3% of the final fattening weight). The proportion of fat contained in the stomach & bowels decreased with the feeding of straw or faecal solids. Other organs and tissues were not affected by the different types of feeding used. An analysis of the results of slaughtering showed that the feeding of faecal solids did not produce any specific effect.
进行了3次饲养试验,其中使用了来自猪粪便的干燥和倾析固体,且比例各不相同。在试验期结束时,共屠宰了55头育肥牛。此外,在这些试验中还测定了一些瘤胃生理学的特征数据。在饲喂含粪便固体的日粮时,所发现的乙酸盐和丙酸盐的摩尔比例介于精料饲喂时观察到的比例和饲喂含40%或50%秸秆的商业食品颗粒时确定的比例之间。当饲喂含粪便固体的日粮时,发现丁酸盐的摩尔比例略有增加。饲喂含较高比例粗饲料日粮的非禁食动物的屠宰体重显著较低(0;50%秸秆;25%秸秆 + 25%粪便固体;50%粪便固体:分别为最终育肥体重的55.7%、51.9%、51.1%或52.2%)。它们的肉质比例较低,胃和肠道中的消化物比例较高(分别为最终育肥体重的11.4%、18.4%、17.0%或16.3%)。胃和肠道中所含脂肪的比例随着秸秆或粪便固体的饲喂而降低。其他器官和组织未受到所用不同类型饲喂的影响。屠宰结果分析表明,粪便固体的饲喂未产生任何特定影响。
