“…Sheep, as a grazing animal, are susceptible to nutritional deficiencies, because of local variation in the concentrations of these elements in pasture plants. The average Cu blood concentration of ewes in this study was in the adequate range which is 0.70-1.00 µg/dl according to Page et al (2018). According to the NRC (2007) recommendation for Zn, Fe, Cu, Se, Mo and Co in feeds for sheep the range is 20-33 mg/kg, 30-50 mg/ kg, 7-11 mg/kg, 0.1-0.2 mg/kg, 0.5 mg/kg and 0.10-0.20 mg/kg dry matter, respectively.…”

“…The serum Co concentrations in adult cattle are typically between 0.3 and 1.1 ng/ml (Herdt and Hof 2011), which is more compared to the present research. However, Page et al (2018) reported adequate ranges of the blood serum concentration for Co > 0.10 ng/ml. In the present study low concentrations of Cd and As were determined.…”

“…Iron and Mo consumption was higher than the recommended level, but the Fe level below 500 mg/kg dry matter is considered as harmful (NRC 2007). For the blood serum Fe concentration Page et al (2018) reported an adequate range of 116-122 µg/ dl, marginal deficient concentration of 77-116 µg/dl, and deficient concentration as < 77 µg/dl. The determined Fe deficient concentration in the blood of ewes during lactation may be associated with more sources, for example with soil acidity as a low pH enhances Fe absorption by the plant.…”

The aim of the present research was to determine the changes in macromineral and trace element concentrations in ewes’ blood during the lactation period. Thirty-six Travnik pramenka ewes at the average age of 3–5 years were included in research and they were evaluated at three stages of lactation: early stage (40 ± 5 days of lactation), medium stage (80 ± 5 days of lactation) and late stage (120 ± 5 days of lactation). In ewes’ blood concentrations of macroelements (Ca, P, K, Na, Mg) and trace elements (Fe, Cu, Zn, Mo, Co, Se, Cd, As) were determined. The average concentrations of macroelements and trace elements in the blood of ewes during lactation were mostly within the reference values. Se concentrations in blood were close to the deficient ones, while concentrations of Cd and As were negligible. Concentration of Ca in blood was the lowest in the early lactation stage, higher in the late stage, and the highest in the medium stage (88.25 mg/l, 96.43 mg/l and 103.43 mg/l, respectively). A significant increase in the concentrations of Mg, Co and Cd and a significant decrease in the concentrations of Na, Fe, Cu, Zn, Mo and Se were found in blood with lactation progress. Significant correlations between the studied parameters were found, especially between macroelements (Ca : K, P : Na, K : Na, K : Mg). Positive correlations were found between some macroelements and trace elements (Ca : Co, Ca : Cd, K : Co, Na : Zn, Na : Se) and between trace elements (Fe : Cu, Cu : Zn, Cu : Mo, Cu : Se, Zn : Se, Mo : Se and Co : As). Negative correlations were found between Ca and Cu, Ca and Mo, P and Cd, K and Cu. Obtained results may help in monitoring the nutritional status and health of ewes during the lactation period, providing a clearer idea related to the supply of macrominerals and trace elements to ewes. Besides, results indicated that the environment of the farming area was not polluted with toxic elements.

Forty-eight hair lambs (12.7 ± 1.9 kg BW) that grazed Panicum maximum pasture in the daytime and were kept in yards overnight were used to evaluate the influence of a feed supplement on growth performance, plasma minerals and metabolites. Lambs were randomly assigned to two treatments: no feed supplement (control) and feed supplement (300 g/head per day). The growth performance trial lasted 77 days. At the end of the trial, blood samples were collected to determine plasma minerals and metabolites. Feed supplementation improved total BW gain, ADG and feed conversion as compared to no supplementation. Supplemented lambs had higher serum concentrations of total protein, albumin, globulin and glucose than lambs not supplemented. Packed blood cell volume, haemoglobin, urea and cholesterol, as well as blood mineral values in lambs not supplemented were similar to those of supplemented lambs. Feed supplementation of growing lambs grazing pasture in the daytime and kept in yards overnight is an important management strategy for improving growth performance and some blood metabolites related to health and nutritional status.

“…Changes in external factors, including daily feed or environmental stressors, can be observed in the blood of the affected animals. A survey conducted to quantify serum mineral concentrations in Montana ram lamb populations indicated that approximately 9.5% of ranch flocks were deficient and 57.1% were marginally deficient in Zn [ 24 ]. This can apply to other mineral profiles as well.…”

Objective: Combination of two stressors on alteration of mineral footprints in animals needs due attention to meet maximum production and welfare, particularly in grazing sheep. This study tested whether ewes (Ovis aries) exposed to water deprivation and thermal–humidity stressors had altered mineral footprints in their wool, serum, urine, and feces.Methods: Nine ewes (age = 3 years; mean body weight = 41±3.5 kg) were divided among a control group with free access to water, and treatment groups with water deprivation lasting either 2 h (2hWD) or 3 h (3hWD) after feeding. Using a 3×3 Latin square design, animals were assigned to treatment groups for three sampling periods of 21 days each (n = 9). Blood was collected by jugular venipuncture. Wool was collected at the end of periods 2 and 3. Metabolic crates designed with metal grated floors were used for urine and feces collection. We measured sodium (Na), magnesium (Mg), phosphorus (P), chloride (Cl), calcium (Ca), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn).Results: The wool mineral levels did not differ between the treatment groups, although K was marginally lower (p = 0.10) in the 2hWD group. The serum and urine mineral levels did not differ between the treatments (p>0.05). Fecal K was significantly lower in the 2hWD group than in the other groups (p≤0.05).Conclusion: In conclusion, water deprivation and thermal-humidity exposure altered the excretion of K, but not of other minerals, in the wool, urine, feces, or serum of ewes. Thus, no additional mineral supplementation is needed for water deprived ewes during thermalhumidity exposure.
