A total of 7,500 samples from 5 swine breeding complexes with 200,000 hybrid Camborough pigs were studied morphologically and bacteriologically. The raising technologies used on all complexes were of industrial type or semi-industrial and extensive. A description is given of the simultaneous participation of the following nosologic units: colibacteriosis, responsible for 13 to 14 per cent of the total mortality rate in newborn pigs; bronchopneumonia--causing 6 to 39 per cent losses in the other age groups; and dysentery with salmonellosis--inflicting 5 to 9 per cent losses. Underlined is the great advantage of the industrial technologies of animal raising as against the conventional ones in the prevention of these diseases in hybrid pig breeding. Tested were effective programmes for the prophylaxis associated with the individual nosologic units. More essential were the following: active immunoprophylaxis with live attenuated vaccines against colibacteriosis and salmonellosis; elimination of the alimentary stress factor in dysentery; disinfections of premises by gassing with a mixture of ammonium nitrate and chlorinated lime in a 1:2 ratio. However, all measures proved effective when the principle of "all in, all out' was observed which is essential part of the Camborough industrial raising technologies.
对来自5个拥有20万头坎布罗杂交猪的种猪养殖综合体的7500份样本进行了形态学和细菌学研究。所有养殖综合体采用的养殖技术均为工业化或半工业化及粗放型。文中描述了以下疾病单位的同时出现情况：大肠杆菌病，占新生仔猪总死亡率的13%至14%；支气管肺炎，在其他年龄组造成6%至39%的损失；痢疾与沙门氏菌病，造成5%至9%的损失。强调了在杂交猪养殖中，与传统养殖技术相比，工业化养殖技术在预防这些疾病方面的巨大优势。测试了与各个疾病单位相关的有效预防方案。以下几点更为重要：用减毒活疫苗对大肠杆菌病和沙门氏菌病进行主动免疫预防；消除痢疾中的营养应激因素；用硝酸铵和漂白粉按1:2比例混合进行熏蒸对养殖场所进行消毒。然而，当遵循“全进全出”原则时，所有措施都证明是有效的，这是坎布罗工业化养殖技术的重要组成部分。
