A significant difference of several hours in the death of 10 day old embryonating eggs acclimated at 99 F and 95 F incubation temperature has been observed following incubation of six strains of NDV, GB, Herts, KM, Roakin, NaJ and B1 by the allantoic route. The embryo died much earlier at 99 F than at 95 F. Considering all log dilutions tested, the mean difference in death time of embryos between tha two incubation temperatures were found to be as follows: GB: 9 to 15 hours; Herts: 9.2 to 14.2 hours; KM: 11.6 to 12.6 hours; Roakin: 8.5 to 14.8 hours; NaJ: 10.4 to 11 hours; and Bi: 10 to 11 hours. Similarly, an earlier embryonic death was observed at 99 F than at 95 F in the 7, 10 and 12 day old embryonating eggs following allantoic inoculation of Roakin strainof NDV. |
