In conclusion, our data suggests that while differences in circulating NO2− and NO3− concentrations after oral administration of distinct NO3−-rich supplementation sources are moderate, concentrations of metabolic by-products may show greater-than-expected variability; the significance of the latter observation for the biological effects under study remains to be investigated.
Forty-eight multiparous cows were used in a randomized complete block design experiment with a 2 × 2 factorial arrangement of treatments to determine the interaction between chromium propionate (CrPr) supplementation and sources of corn varying in ruminal starch fermentability on production responses during the postpartum (PP) and carryover periods.
The results indicated that neither Se supplementation nor Se source affected dry matter intake, milk yield, milk composition, or blood biochemical parameters, except for milk fat percentage.
Sixteen Holsteins cows were used in a Latin square design experiment to determine the effects of extruded flaxseed (EF) supplementation and grain source (i.e., corn vs. barley) on performance of dairy cows.
Without oral supplementation, the primary source of vitamin D3 (cholecalciferol) is the skin upon exposure to ultraviolet-B radiation (UVB).
All Participants will be asked to avoid ongoing supplementation of any source that contains additional LCn-3s.
Therefore the denitrification process of brines requires the external supplementation with carbon source, which can be simply realized by combining wastes from vegetable oil production.
To evaluate the maximum synthetic capacity of the yeast system for the intracellular expression of hPGAEc, a transient phase of the process was optimized (the phase required for the transition of cell metabolism from glycerol to methanol in terms of concentration of the methanol as an inducer and profile of the carbon source supplementation).
The influence of supplementation of carbon sources (glucose, maltose, starch, sucrose, and lactose at 1% w/v) and nitrogen sources (yeast extract, urea, sodium nitrate, ammonium sulphate, and ammonium chloride at 1% w/v) has been studied.
However, the levels of β-glucosidases are mostly low and, thus, require supplementation from other sources such as Aspergilli.
