An experiment was carried out at Katherine, N.T., Australia, to compare the effects of burning and clipping of native tropical tall grass range at various dates during the wet season with respect to total forage yields, composition of forage, and crude protein percen-
tage. Total forage yield on the untreated plots was greater than on any treated plots. The burned plots increased in total yield with later date of burning. the clipped plots first decrea-
sed and then increased in total yield as the date of clipping advantaced. A significant difference in total yield between clipped and burned plots was recorded only from plots treated just prior to the wet season, when burned plots gave a lower yield than clipped plots. The percent composition by weight of Chrysopogon fallax increased on the clipped
and burned plots, but Sorghum plumosum declined considerably on both treatments. Themeda australis was reduced on the burned plots but not significantly changed on the clipped. Clipping and burning increased crude protein percentage but there was little difference in total crude protein yields between the clipped and burned plots or between various treatment dates. The untreated plots greatly exceeded both clipped and burned in total crude protein yields. Seven weeks after the last rains the amount of crude protein remaining on the plots for use during the dry season was highest on the untreated plots and decreased with later dates of treatment on the clipped and burned plots. The plots treated one week after the last rains had no measurable regrowth six weeks later. It would seem that wet season burns are detrimental to quantity and quality of forage produced. The earlier the burn, the more afavourable is the forage situation dor dry season use. Only very hot burns have a more serious effect on forage regrowth.

RESUMO - No período de 1972 a 1978 isolaram-se e tipificaram-se quatorze amostras de Campylobacter fetus (Vibrio fetus), a partir de esmegma, lavado prepucial, sêmen, muco vaginal e conteúdo estomacal de fetos abortados, de bovinos com problemas de reprodução. As amostras isoladas foram identificadas como Campylobacter fetus subespecies fetus e intestinalis. ABSTRACT - From 1972 to 1978,14 strains of Campylobacter fetus (Vibrio fetus) were isolated and typified, starting from a part of smegma, preputial washing, semen, vaginal mucus, stomach content of aborted fetuses of bovines with reproduction problems. The isolated samples strains were identified as Campylobacter fetus, subspecies fetus and intestinalis. |
