The aim of this study was to evaluate the value of transfaunation in the treatment and recovery of goats and sheep with acute rumen lactic acidosis (ARLA) experimentally induced. Six goats (41.2±5.6kg) and six sheep (46.8±4.57kg), non-pregnant and non-lactating, received 15g of sucrose per kilogram of body weight for the disease induction. The ARLA was induced in each animal twice with an interval of 30 days after full recovery of the first induction. Therapeutic procedures consisted in removal of the rumen fluid content by washing and siphoning with an esophageal tube and correction of metabolic acidosis with intravenous electrolyte solutions containing sodium lactate or sodium bicarbonate. The transfaunation was part of only one of each animal treatment and consisted in administration of two liters of rumen fluid colleted from a healthy cow. Complete recovery was assessed by physical examinations and rumen fluid examinations up to four days after therapeutic procedures. The efficacy of treatment protocols, with or without transfaunation was compared. The protocol used was effective in induce the disease and goats and sheep showed clinical signs of maximum intensity (apathy, rumen stasis, abdominal distension, diarrhea and moderate dehydration) 16 hours after the intraruminal administration of sucrose. At this moment, the characteristics of ruminal fluid were similar to the typical ARLA. The frequency of ruminal movements became normal on the third day after therapeutic procedures, with no difference between species, and regardless transfaunation. The ruminal fluid transfer did not accelerate the recovery of appetite, considered normal only on the fourth day after treatment in both species. When transfauntation was received, goats and sheep showed recovery of characteristics of color, odor and consistency faster than when they did not receive. The fermentative activity of the rumen microbiota was not impacted by transfaunation and normalized two and three days after therapeutic procedures in sheep and goats, respectively. The transfaunation promoted faster return of the protozoa population, which was observed 24 hours after therapeutic procedures in both species. When the animals did not receive transfaunation, the protozoa returns occurred only on the second day after therapeutic procedures. Full recovery of the animals occurred within four days, regardless of transfaunation. In conclusion, the ruminal fluid transfer can not be considered crucial for the treatment and convalescence of goats and sheep affected by ARLA.
