Three sows with agalactia and mastitis were compared with 3 normally lactating sows at 8, 16, 24, and 32 hours postpartum. Bacteriologic examination of milk resulted in isolation of Klebsiella pneumoniae or Escherichia coli from affected glands of all 3 agalactic sows. Milk from clinically normal glands of affected sows and from glands of normal sows was culture-negative for coliforms. Affected sows had higher rectal temperatures and lower milk yields, and pigs from affected sows had lower mean weights, but these differences were not significant. Mean total white blood cell counts and plasma protein to fibrinogen ratios were lower in mastitic sows at all 4 periods; differences were significant at certain periods in both cases. Evidence indicated that leukopenia appeared early, 8 to 16 hours postpartum, and was followed by increasing plasma fibrinogen content. Packed cell volumes and plasma concentrations of corticoid, estrone, and estradiol did not differ. Plasma progesterone content was higher in mastitic sows at all periods, but the differences were not significant.
在产后8、16、24和32小时，对3头患无乳症和乳腺炎的母猪与3头正常泌乳的母猪进行了比较。对乳汁进行细菌学检查，结果在所有3头患无乳症的母猪的患病乳腺中分离出肺炎克雷伯菌或大肠杆菌。患猪临床正常乳腺的乳汁以及正常母猪乳腺的乳汁经培养均未检出大肠菌群。患猪的直肠温度较高，产奶量较低，患猪所产仔猪的平均体重也较低，但这些差异并不显著。在所有4个时间段，患乳腺炎母猪的平均白细胞总数和血浆蛋白与纤维蛋白原的比率均较低；在这两种情况下，某些时间段的差异具有显著性。有证据表明，白细胞减少症在产后8至16小时出现得较早，随后血浆纤维蛋白原含量增加。红细胞压积以及皮质激素、雌酮和雌二醇的血浆浓度没有差异。在所有时间段，患乳腺炎母猪的血浆孕酮含量均较高，但差异不显著。
