“…The pH values observed in this study were in the normal range of ruminal fermentations [35], and not affected by additional Cu. Contrary to this study, a significant decrease of pH during in vitro rumen fermentations was observed by Vaswani et al [14], following a supplementation of 8 mg/kg DM of Cu (as CuSO4). However, numerous studies registered no effect of Cu on ruminal pH when supplementing steers with a high dosage (25 mg/kg DM) of inorganic Cu [13,30,50,52].…”

“…In the present study, the results registered during the 70hrs incubations with rumen juice suggest that CuSO4 has no significant effect on TGP. Similar to this, it was found that supplementing inorganic Cu (as CuSO4) at different rates (4, 8 or 16 mg/kg DM) to in vitro incubations with rumen juice collected from 3 freshly slaughtered cattle, induced no significant variation in the gas production [14]. However, some numerically higher TGP was observed when Cu was added at the start or after 24hrs of fermentation (CuS_0.01_0h, CuS_0.015_0h and CuS_0.015_24h, respectively), suggesting a slight improvement of fermentations.…”

“…Vaswani et al [14] and Zhang et al [51], who noted increased in vitro degradability of dry matter when inorganic Cu was supplemented at levels that varied between 4 and 30 mg/kg DM. No significant effect of Cu supplementation was observed regarding total VFA production, persistent with the lack of increased TGP.…”

“…In vitro studies with Cu showed that a high dosage of inorganic Cu (as CuSO4) has a negative effect on rumen fermentation [12], and VFA production is inhibited [13]. However, an addition of 8 mg/kg DM of inorganic Cu (as CuSO4) significantly improved the in vitro dry matter degradation and tended to increase the total microbial biomass [14]. Furthermore, the addition of 5, 7.5 and 10 mg/kg DM of Cu (as coated CuSO4) to dairy cows' diet increased organic matter (OM) and neutral-detergent fiber (NDF) degradation, as well as the populations and activity of cellulolytic bacteria, like Rumminococcus albus, Ruminococcus flavefaciens and Fibrobacter succinogenes [15].…”

The aim of this study was to assess the effects of supplementation of inorganic sources of manganese (MnO, MnSO4), zinc (ZnO, ZnSO4) and copper (CuSO4) at different levels (0.06%DM for Mn, 0.05%DM for Zn; and 0.01 and 0.05%DM for Cu) on in vitro rumen fermentation, solubility and bioavailability. Fermentation activity was measured by total gas production (TGP) and dry matter degradability after 70hrs of fermentation (dDM%). Trace-mineral (TM) solubility was estimated by the TM concentration in the supernatant of the final fermentation medium (SOL) and TM bioavailability by the TM concentration in a bacterial enriched fraction (BACT). Mn (regardless of source) and ZnO tended (p&lt;0.10) to decrease, while Cu showed no significant effect on TGP. The addition of inorganic Mn and of ZnO tended (p&lt;0.10) to decrease, ZnSO4 tended to increase (p&lt;0.10), whilst Cu showed no effect on dDM%. Concerning solubility, Mn (MnO and MnSO4), ZnSO4 and CuSO4 significantly (p&lt;0.05, p&lt;0.001 and p&lt;0.01) increased, while ZnO did not affect TM content of the SOL. These results indicate that MnSO4, ZnSO4 and CuSO4 are highly soluble, MnO is quite soluble, while ZnO has a low solubility in the rumen. Based on the TM content of BACT, MnO, MnS4 and CuSO4 have a high bioavailability, while ZnO is poorly assimilated by rumen bacteria. However, the lack of clear inhibition or improvement of fermentations suggests that the rumen microbiota has low requirement for TM supplementation.
