“…It has been consistently observed that the highest ruminal H 2 S concentration, PEM incidence and subclinical losses, occur between 10 and 35 days after the beginning of S excess intake (Drewnoski et al, 2014; Qian et al, 2020). Indeed, the extension of the present study was enough to yield a significant increase of ruminal H 2 S concentration, but not of DSRB concentration.…”

“…Hence, high ruminal H 2 S concentration has been associated with PEM occurrence (Gould, 2000) and performance detriment in FC (Richter, 2011; Uwituze et al, 2011). Ruminal H 2 S maximum production occurs about 10 to 35 days after the beginning of excessive S intake (Qian et al, 2020), thus the highest incidence of the aforementioned clinical and subclinical conditions (Drewnoski et al, 2014). The mechanism associated with ruminal H 2 S increase has not been elucidated, but it has been suggested that it could be related to changes in the DSRB population (Drewnoski et al, 2014; Richter, 2011).…”

“…Sulphur (S) is an essential macromineral for life and optimum performance of cattle (NRC, 2005). Sulphur supplementation could mitigate ruminal methane emission (Lan & Yang, 2019; Qian et al, 2020) and improve feed digestibility (Uwituze et al, 2011). However, S dietary excess can limit animal performance and increase polioencephalomalacia (PEM, brain cortex necrosis) incidence (Drewnoski et al, 2014), one of the most common neurological disorders in young cattle (Dore & Smith, 2017).…”

Sulphur (S) dietary excess can limit productive performance and increase polioencephalomalacia (PEM) incidence in feedlot cattle (FC). Sulphur excess ingested is transformed to hydrogen sulphide (H2S) by sulfo‐reducing ruminal bacteria (SRB), being high ruminal H2S concentration responsible for aforementioned damages. As the ruminal mechanisms involved in H2S concentrations increase have not been elucidated, this study aimed to evaluate the ruminal environment, and the association between ruminal H2S and dissimilatory SRB (DSRB) concentration in FC experimentally subjected to S dietary excess. Twelve crossbred steers were randomly assigned to one of two dietary S levels (6 animals per treatment): low (LS, 0.19% S) and high (HS, 0.39% S obtained by sodium sulfate inclusion at 0.86%). The study lasted 38 days, and on days 0, 22 and 38, ruminal gas samples were taken to quantify H2S concentration, and ruminal fluid to determine total bacteria, DSRB, protozoa, volatile fatty acid and ammonia nitrogen concentration. For ruminal H2S concentration, S dietary × sampling day interaction was significant (p < 0.001), so that the greater concentration was observed on days 22 and 38 with the HS diet. The remaining ruminal parameters were not affected by dietary S level, and no significant correlation between H2S and DSRB concentrations was observed. The ruminal adaptation that maximizes H2S production in FC consuming S excess does not seem to be associated with biological or biochemical alterations, nor DSRB concentration changes. The microbial diversity and ruminal environment were resilient to the S excess evaluated, suggesting that 0.39% of dietary S achieved by 0.86% sodium sulfate addition, could be used without disturbances on digestion nor health of FC.

“…According to the FAO, livestock farming is responsible for around 18% of methane (CH 4 ) emissions and 9% of carbon dioxide (CO 2 ) production [2], as these gases are the result of ruminal fermentation of feed, mainly from fibrous carbohydrates; and although their production is inevitable, high amounts represent a loss of gross energy of between 2 and 12% for the animals [3]. Other gases produced by rumen include carbon monoxide (CO), which indirectly contributes to global warming as a precursor to ozone, and hydrogen sulfide (H 2 S) [4], can provide an alternate sink for metabolic hydrogen (H 2 ), which decreases CH 4 production [5]. However, H 2 S is easily absorbed in the intestinal wall of ruminants, so in high concentrations, it can be toxic and even induce polioencephalomalacia, a harmful brain disease in animals [6].…”

The objective of this study was to evaluate the effect of different percentages of alfalfa (Medicago sativa L.) hay (AH) and doses of guanidinoacetic acid (GAA) in the diet on the mitigation of greenhouse gas production, the in vitro rumen fermentation profile and methane (CH4) conversion efficiency. AH percentages were defined for the diets of beef and dairy cattle, as well as under grazing conditions (10 (AH10), 25 (AH25) and 100% (AH100)), while the GAA doses were 0 (control), 0.0005, 0.0010, 0.0015, 0.0020, 0.0025 and 0.0030 g g−1 DM diet. With an increased dose of GAA, the total gas production (GP) and methane (CH4) increased (p = 0.0439) in the AH10 diet, while in AH25 diet, no effect was observed (p = 0.1311), and in AH100, GP and CH4 levels decreased (p = 0.0113). In addition, the increase in GAA decreased (p = 0.0042) the proportion of CH4 in the AH25 diet, with no influence (p = 0.1050) on CH4 in the AH10 and AH100 diet groups. Carbon monoxide production decreased (p = 0.0227) in the AH100 diet with most GAA doses, and the other diets did not show an effect (p = 0.0617) on carbon monoxide, while the production of hydrogen sulfide decreased (p = 0.0441) in the AH10 and AH100 diets with the addition of GAA, with no effect observed in association with the AH25 diet (p = 0.3162). The pH level increased (p < 0.0001) and dry matter degradation (DMD) decreased (p < 0.0001) when AH was increased from 10 to 25%, while 25 to 100% AH contents had the opposite effect. In addition, with an increased GAA dose, only the pH in the AH100 diet increased (p = 0.0142 and p = 0.0023) the DMD in the AH10 diet group. Similarly, GAA influenced (p = 0.0002) SCFA, ME and CH4 conversion efficiency but only in the AH10 diet group. In this diet group, it was observed that with an increased dose of GAA, SCFA and ME increased (p = 0.0002), while CH4 per unit of OM decreased (p = 0.0002) only with doses of 0.0010, 0.0015 and 0.0020 g, with no effect on CH4 per unit of SCFA and ME (p = 0.1790 and p = 0.1343). In conclusion, the positive effects of GAA depend on the percentage of AH, and diets with 25 and 100% AH showed very little improvement with the addition of GAA, while the diet with 10% AH presented the best results.
