Background Acidosis is one of the most common rumen diseases characterized by changes in the rumen environment and the circulatory system. Recent alternative trends in rearing small ruminants have led to the use of probiotics, rumenotorics and prebiotics to treat acidosis in animals. Purpose This study aimed to evaluate the efficacy of probiotics and the combination of probiotics with prebiotics and probiotics with rumenotorics for the treatment of acidosis in sheep. Methods This experimental study was conducted from September 2018 to May 2019. For the therapeutic study, 25 sheep were randomly divided into 5 equal groups. Acidosis was induced by an oral dose of 50 g/kg with wheat flour after a 24 hour fast. Four regimens of therapy were employed: PT probiotics, PPT probiotics with prebiotics; PRT probiotics with rumenotorics and standard ST treatment were adopted. Before and after therapy, laboratory analyses on rumen fluid, serum analysis, physical signs, and hematological changes were conducted. Results When probiotics were combined with rumenotorics (PRT), the mean standard deviation of rumen pH at day zero was 4.96±0.837 (PRT). Rumen pH improved from day one today three to 5.92±0.54, 6.30±041 and 6.75±0.34, respectively. The change in rumen pH was statistically significant after treatment on day 3 (p=0.002). The therapeutic regimens of PRT had improved heart rate and respiratory rate after treatment and the change was statistically significant (p=0.006 and p=0.000) compared to the control group. The PCV of the PRT treated sheep was also improved. Conclusion Probiotics with rumenotorics were the most successful therapeutic regimen for the treatment of ruminal acidosis in sheep. Therefore, the use of probiotics with rumenotorics is the promising alternative for the treatment of acidosis.

“…This increase in respiration rate was may be due to dehydration and stimulation of respiratory center by increased of carbon-dioxide (CO 2 ) content in blood and decreased blood pH. While, increase in respiration rate and pulse rate was observed similar to reported previously (Haji et al, 2006). Goats had shown decreased blood circulating volume, heamoconcentration and severe dehydration in lactic acidosis, one goat died due to severe lactic acidosis, these signs were similar to the previous reports that increase in the release of histamine and absorption of the lipopolysaccharide endotoxins and other vasoactive agents attribute to rapid death in goats, these results are in agreements to the earlier reports that pH of (<5.00) is being lethal for goats (Chand et al, 2016).…”

“…Fiber fermentation is a complex process which requires the combined action of multiple microbial groups ( 41 ), therefore it may be expected that a greater rumen microbial diversity would favor the adaptation and utilization of fibrous diets by the host. Our study showed that all animals were ultimately adapted to the forage diet without experiencing stress or digestive disorders based on the similar levels of hair cortisol, blood metabolites and absence of diarrhea across treatments ( 42 ). However, this adaptation process was substantially faster for RFF and RFC given their higher DMI and rumen VFA concentration than reported for CTL animals at 4 d after the dietary shift, possibly as a result of a higher forage degradation by the rumen microbes ( 43 ).…”

IntroductionThis study explores if promoting a complex rumen microbiota represents an advantage or a handicap in the current dairy production systems in which ruminants are artificially reared in absence of contact with adult animals and fed preserved monophyte forage.MethodsIn order to promote a different rumen microbial diversity, a total of 36 newborn goat kids were artificially reared, divided in 4 groups and daily inoculated during 10 weeks with autoclaved rumen fluid (AUT), fresh rumen fluid from adult goats adapted to forage (RFF) or concentrate (RFC) diets, or absence of inoculation (CTL). At 6 months of age all animals were shifted to an oats hay diet to determine their ability to digest a low quality forage.Results and discussionEarly life inoculation with fresh rumen fluid promoted an increase in the rumen overall microbial diversity which was detected later in life. As a result, at 6 months of age RFF and RFC animals had higher bacterial (+50 OTUs) and methanogens diversity (+4 OTUs) and the presence of a complex rumen protozoal community (+32 OTUs), whereas CTL animals remained protozoa-free. This superior rumen diversity and presence of rumen protozoa had beneficial effects on the energy metabolism allowing a faster adaptation to the forage diet, a higher forage digestion (+21% NDF digestibility) and an energetically favourable shift of the rumen fermentation pattern from acetate to butyrate (+92%) and propionate (+19%) production. These effects were associated with the presence of certain rumen bacterial taxa and a diverse protozoal community. On the contrary, the presence of rumen protozoa (mostly Entodinium) had a negative impact on the N metabolism leading to a higher bacterial protein breakdown in the rumen and lower microbial protein flow to the host based on purine derivatives urinary excretion (-17% to -54%). The inoculation with autoclaved rumen fluid, as source of fermentation products but not viable microbes, had smaller effects than using fresh inoculum. These findings suggest that enhancing rumen microbial diversity represents a desirable attribute when ruminants are fed forages in which the N supply does not represent a limiting factor for the rumen microbiota.
