Breeding cycle of the flea Cediopsylla simplex is controlled by breeding cycle of host.
Maturation of female Cediopsylla simplex takes place on the pregnant rabbit and nestlings but not on the estrous doe. If matured fleas are transferred to the estrous doe their ovaries are resorbed.

Blood coagulation studies in domestic pigs (Hanover breed) and minipigs (Goettingen breed).
Blood coagulation studies were performed on 60 Hanover domestic pigs ready for slaughter and a total of 84 Goettingen minipigs. A tendency to hypercoagulability was found in these pigs, expressed in a shortened PTT, r- and k-time in the thromboelastogram and a slightly reduced plasminogen and plasmin level. Many values were similar to those of man. Thrombin time was longer. This may be due more to enhanced formation of fibrin degradation products (anti-thrombin VI) than to greater amounts of endogenous heparin being released. The longer reptilase and thrombin coagulase times support this. The thrombocyte count differed only slightly. The findings suggest that the Goettingen minipigs and Hanover domestic pig are suitable animals for comparative blood coagulation studies.

[Examination of the udder quarters of the first calving for Streptococcus group B of breeding cow market management of the Rhinish Association for the Schwartzbund cattle breed (RVS)].
Quarter milk samples from 344 heifers were examined on group-B-streptococci. In none of the 1376 milk-samples Streptococcus agalactiae could be detected. The problem of examination of B-streptococci is discussed and proposals from the examination on udders of heifers are given.
