摘要

An experiment was conducted to develop an effective defaunation protocol for sheep and goats under Indian conditions. Two each of adult cannulated Malpura rams and Kutchi bucks were maintained under stall feeding on ad libitum cenchrus hay as basalroughage with 40% of their total dry matter requirement as concentrate mixture. Daily dry matter intake/kg body weight was higher (P<0.01) in faunated sheep than similar goats. The values of pH and total VFA concentrations in the rumen of faunated sheepand goats were similar, however, concentrations of total nitrogen, ammonia-nitrogen and total ciliate protozoal population were higher (P<0.01) in the rumen of faunated goats than faunated sheep. The ideal dose of sodium lauryl sulfate (SDS) for defaunation was evaluated by initial dosing with 6 g SDS/100 kg body weight (after 24 h of fasting). Scanning of strained rumen liquor (SRL) one day after defaunation indicated complete elimination of holotrich protozoa in both the species, while spirotrichs were still detected. Therefore, after seven days, these animals were again defaunated with 8 g SDS/100 kg body weight after 24 h of fasting and it was observed that the dose effectively defaunated both sheep and goats. Animals were then maintained in stallfeeding conditions under normal management practices. After defaunation, rumen liquor samples were collected from all animals before feeding on alternate days to observe the reappearance of rumen ciliate protozoa. After 16 days of defaunation Entodiniumfirst appeared in the rumen of both species followed by spirotrichs and holotrichs. It is concluded that 8 g SDS/100 kg body weight in sheep and goats effectively defaunated them and that under routine feeding management the protozoa re-established after16 days.
