“…These results are also in agreement with our previous findings that the digestibility of nutrients and the utilization of supplemental Se were higher than those of control animals (Hernández-Calva et al, 2007). Besides, Wang et al (2009) and Shi et al (2011) reported an improvement in total digestibility of nutrients and NDF due to Se addition from 0.15 to 0.45 mg Se/kg DM. However, Serra et al (1994b) showed that addition of 0.2 mg Se had no effect on NDF digestibility in sheep.…”

“…The same way, other authors have reported that the production of acetic, propionic, butyric acids, and total VFA was increased by Se supplementation (Hidiroglou and Lessard, 1976;Wang et al, 2009), and by vitamin E or Se/vitamin E supplementation . The increased VFA concentrations with Se supplementation suggest a greater ruminal microbial fermentation rate (Wang et al, 2009). In other studies, ammonium (Naziroglu and Aksakal, 1997) or methane 2.9 C = control, DM = dry matter 1 Se main effect, P < 0.01, 2 grain main effect, P < 0.01, 3 grain main effect, P < 0.05, 4 Se × grain effect, P < 0.01, 5 Se linear effect 50% grain, P < 0.01, 6 Se linear effect 70% grain, P < 0.01, 7 Se quadratic effect 50% grain, P < 0.01, 8 Se quadratic effect 70% grain, P < 0.05 (Liu et al, 2007;Wang et al, 2009).…”

Ruminal bacteria and ruminal protozoa were not affected in our experiment but, in general, Se availability in the rumen facilitates its use by the ruminal microorganisms (Hidiroglou et al, 1968).…”

ABSTRACT:The objective was to evaluate the effect of different levels of selenium with two levels of grain corn in the diets on ruminal, postruminal, and total tract digestion of nutrients, ruminal fermentation characteristics, and selenium balance in lambs. A split-plot design was used in four periods with repeated Latin square using eight Suffolk × Dorset male lambs with four levels of selenium (sodium selenite, Na 2 SeO 3 ), without adding selenium, 0.3, 0.6, and 0.9 mg of selenium/kg dry matter (DM) with 70 and 50% of corn grain in the diet. The four selenium levels affected organic matter as follows: starch, neutral detergent fibre, nitrogen and selenium excretion; selenium ruminal digestion; organic matter, neutral detergent fibre, nitrogen and selenium postruminal digestion; and organic matter, neutral detergent fibre, nitrogen and selenium total tract digestion (P < 0.05). Starch and organic matter flow decreased with 0.6 and 0.9 mg of selenium with the 70% grain diet (P < 0.05). Selenium flow increased linearly with selenium levels (P < 0.01) with both levels of grain. Selenium supplementation increased linearly selenium concentration in ruminal fluid (P < 0.01), but did not affect other ruminal characteristics. Also, selenium absorption and retention was increased by selenium concentrations (P < 0.01). The apparent absorption of selenium increased (31%, P < 0.01) with the 70% grain diet. In conclusion, the high content of nonstructural carbohydrates improved the availability of selenium and 0.9 mg of selenium/kg DM improved the absorption and availability of selenium.

“…Inclusion of LY has been shown to stabilize the rumen environment through higher pH values and enhance fiber digestion [2]- [4]. These key results certainly explain why the impact of a LY supplementation has been studied primarily on energetic metabolism, in relation with the dietary forage: concentrates ratio [5]- [10].…”

BACKGROUND Considering the insufficient ruminal synthesis of folic acid (FA), the higher degradability of FA, and the reduction of sodium selenite (SS) by ruminal microbes into non‐absorbable elemental Se, this study evaluated the effects of rumen‐protected FA (RPFA) and rumen‐protected SS (RPSS) on lactation performance, nutrient digestion and blood metabolites in dairy cows. RESULTS Dry matter (DM) intake and milk composition were unaltered, milk and milk fat yields were higher for both supplements, and milk protein yield was higher for RPFA addition. Digestibility of DM, neutral detergent fibre and acid detergent fibre was higher for both supplements, whereas that of organic matter and crude protein was higher for RPFA addition. Ruminal pH and ammonia N were lower, and concentration of total volatile fatty acids was higher for both supplements. Activity of cellobiase and xylanase was higher for RPFA addition, whereas that of pectinase and protease was higher for both supplements. The populations of total ruminal fungi, protozoa, Ruminococcus flavefaciens and Butyrivibrio fibrisolvens were higher for both supplements. The RPFA × RPSS interaction was significant for α‐amylase activity, total ruminal bacteria and R. albus populations; these three variables were increased by RPSS but the increase was greater when cows were also fed RPFA. CONCLUSION The results indicated that addition of RPFA or RPSS improved lactation performance, nutrient digestibility and ruminal fermentation in dairy cows by stimulating ruminal microbial growth and enzyme activity. © 2019 Society of Chemical Industry
