摘要
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.

本研究的目的是评估经过实验诱导的急性瘤胃乳酸性酸中毒（ARLA）治疗和恢复山羊和绵羊的转移价值。六只山羊（41.2±5。6kg）和6只绵羊（46.8±4.57kg），非怀孕和非哺乳期，每公斤体重接受15g蔗糖用于疾病诱导。在第一次诱导完全恢复后，在每只动物中诱导ARLA两次，间隔为30天。用含有乳酸钠或碳酸氢钠的静脉注射电解质溶液洗涤和虹吸用食道管和代谢性酸中毒校正瘤胃液含量。转移只是每种动物治疗中的一种的一部分，并且包括施用从健康母牛收集的两升瘤胃液。在治疗程序后最多四天通过体格检查和瘤胃液检查评估完全恢复。治疗方案的功效，有或没有transfaunation进行了比较。使用的方案有效诱导疾病，山羊和绵羊表现出最大强度的临床症状（冷漠，瘤胃淤滞，腹腔内给予蔗糖16小时后腹胀，腹泻和中度脱水。这时，瘤胃液的特征与典型的ARLA相似。在治疗程序后的第三天，瘤胃运动的频率变得正常，没有物种之间的差异，也不管转移。瘤胃液体转移没有加速食欲的恢复，在两个物种的治疗后第四天才认为是正常的。当收到transfauntation时，山羊和绵羊显示出颜色特征的恢复，气味和稠度比没有收到时更快。瘤胃微生物群的发酵活性不受转移影响，并分别在绵羊和山羊的治疗程序后两天和三天进行标准化。转移促进了原生动物种群的更快恢复，这在两个物种的治疗程序后24小时观察到。当动物没有接受过转移时，原生动物的返回仅在治疗程序后的第二天发生。无论转移何种情况，动物在4天内完全恢复。结论，对于受ARLA影响的山羊和绵羊的治疗和恢复，瘤胃液体转移不是至关重要的。
