“…In addition, B was shown to improve Ca and Mg bioavailability in cows(Baspinar et al 2017).The results of a recent meta-analysis demonstrated that Cr supplementation signi cantly improves milk production but not composition(Malik et al 2023), also signi cantly in uencing metabolic parameters by reducing non-esteri ed fatty acid levels and increasing glucagon concentrations(Malik et al 2024). Given the role of Cr as an insulin-mimetic, it has been shown that Cr supplementation signi cantly modulates insulin-signaling pathway, although this effect was different in antepartal than post-partal period(Pantelić et al 2018), being also dependent on the energy balance in these periods(Kegley, Spears, 1999).Lactation is associated with decreased plasma Fe and Hb levels, being indicative of higher Fe requirements(Randhawa et al 2009). Correspondingly, simultaneous Fe and Cu de ciency was shown to be associated with reduced milk yield(Abramowicz et al 2021).…”

The objective of the present study was to evaluate serum trace element and mineral levels in low- and high-productive dairy cows during feedlot and pasture periods. Serum trace element and mineral levels were assessed inductively-coupled plasma mass-spectrometry. The obtained data demonstrate that serum Ca, Mg, K, and Na levels increase significantly in the pasture period, and this increase is more evident in high-productive cows. In turn, circulating levels of B, Co, Cr, Fe, I, and Se levels were characterized by a decrease in the pasture period. Despite the lack of group differences in the feedlot period, serum B, Cr, and Fe levels in the pasture period were higher in high-productive cows. In turn, circulating Co and I concentrations in the low-productive cows exceeded those in high-productive animals. Finally, the levels of toxic trace elements in the pasture period were found to be higher in low-productive cows. Discriminant analysis demonstrated that the groups of cows with different milk productivity were clearly discriminated in the pasture but not feedlot period. In addition, multiple regression analysis revealed a significant inverse and positive association of serum Pb and Cr levels with daily milk yield. Taken together, the obtained data demonstrate that the differences in serum trace element and mineral levels between the low- and high-productive cows are more profound in the pasture period. More beneficial trace element and mineral profile in high-productive cows may hypothetically contribute to higher milk yield. However, further more detailed studies are required to elucidate the mechanisms of this association.

Effects of chromium picolinate supplementation on the growth, carcass quality and gene expression of beef during the finishing period

et al. 2010

Four groups of 12 young beef, as similar as possible with respect to age and weight, were fed a basic diet. The addition fed to four groups was 0, 200, 600, and 1,200 mg of organic chromium (chromium picolinate CrPic) per kg concentrated feed. The results showed that there was no effect on overall growth performance and dressing percentage and pure meat percentage when adding different CrPic content, but significant difference was found between 0 group and other three groups in percentage of high grade cuts (P < 0.05). The Cr content in Kidney, Musculus diaphragm, Semitendinosus muscles and Longissimusdorsi tissues have no difference in four groups (P > 0.05), but there was significant difference in liver tissues between 0, 200, 600 groups and 1200 group (P < 0.05). Gene expression analysis indicated that there were no differences in five genes expression in liver and muscle tissues in four groups (P > 0.05), but mRNA expression amount of FOX1, FSTL and MATR3 always had same trends whatever in liver or muscle tissues. However the RPLOP gene expression amount has large difference between liver and muscle.

The effects of oral supplementation of chromium picolinate (CrPic) on various blood parameters and their possible toxicity on the liver, kidneys, lungs, heart, and testis were investigated. Twenty-four Santa Inês (SI) lambs were treated with four different concentrations of CrPic (six animals/treatment): placebo, 0.250, 0.375, and 0.500 mg CrPic/animal/day for 84 days. The basal diet consisted of hay Panicum maximum cv Massai and concentrate. Blood and serum were collected fortnightly for analysis. On day 84, the animals were euthanized, and histopathological analysis in the liver, kidney, heart, lung, and testis was made. The liver and kidney were also submitted to electronic microscopy analysis. Differences between treatments (P < 0.05) were observed for packed cell volume (day 84), hemoglobin (day 84), total plasm protein (day 56 and day 84), and triglycerides (day 70). There was no statistically significant relationship between Cr supplementation and histopathology findings, although some animals treated with supplementary Cr showed morphological changes in the liver, kidney, and testis. Thus, the effectiveness of supplementation with Cr remains in doubt as to its physiological action and toxicity in sheep.
