“…Some authors have explained that meat from kids reared with natural milk has lower a * and greater h ab values because the natural milk of goats is not rich in Fe (Sañudo et al, ). Although grazing goats had normal levels of Se and Fe in plasma (Schweinzer et al, ), a higher level of these elements was found in goat kids that were fed with a milk replacer (Wittek, ). However, Lanza et al () did not find differences in the h ab and a * values of suckling lamb meat even though the iron content of the milk replacer was greater than that of natural milk (Rodríguez et al, ).…”

Most suckling kids are raised on farms for cheese production, and many goat farmers rear kids with milk replacers. The aim of this work was to study the influence of the use of milk replacers on the color of four muscles. A total of 246 suckling kids of eight breeds were slaughtered to achieve carcasses of 5 kg. The color of the biceps femoris , semimembranosus , semitendinosus, and longissimus thoracis muscles was measured with a spectrophotometer, and CIELab coordinates were registered. In addition, the pH of longissimus thoracis was measured. The effect of the rearing system (RS) on the color of the studied muscles is strongly modulated by breed. In general terms, there are two groups of kids according to the color of meat. The first group has great lightness and hue angle including Malagueña, Palmera, and Tinerfeña fed natural and artificial milk. The second group with great redness includes Retinta, Payoya, and Verata fed natural and artificial milk together with Florida fed natural milk and Cabra del Guadarrama fed milk replacers. Hence, farms should consider selecting a breed and RS together. Most of the kid meat with high pH comes from kids raised on milk replacers. Because artificial RSs use very early weaning, which might induce a high pH and dark meat, two artificial rearing strategies can be proposed. The first strategy is to choose less sensitive breeds that produce meat with a normal pH. The second strategy is to restrict suckling of natural milk but minimize separation from the mother.

“…The average concentrations of macroelements and trace elements in the blood of ewes during lactation were mostly within the limits of reference values (Puls 1994;Herdt and Hoff 2011;Schweinzer et al 2017), except for the P concentration which was higher, and Fe which was lower compared to reference values. Assessment of the trace element status in the animal is much more difficult.…”

“…All data were analysed with the statistical software SAS v9.4 ® (SAS Institute Inc., Cary, NC, USA). Reference values for blood macrominerals and trace elements from the laboratory were compared with selected reference values (Puls 1994;Underwood and Suttle 1999;Herdt and Hoff 2011;Schweinzer et al 2017).…”

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.

“…Daily average Zn intake by sheep in dry season, late rainy season and early rainy season were 50.96, 52.44 and 44.84 µg, respectively. Through the circulation system, Zn were uptake by several tissue for biological and biochemistry process, among other for component and cofactor several enzyme, tissue protein synthesis and bone formation which reflected in ADBWG (Soetan et al, 2010;Radwinska and Zarczynska, 2014;Schweinzer et al, 2017).…”

The objective of this study was to study the mineral status of Java thin-tailed (JTT) sheep grazed in Mijen-Semarang, Central Java. Six month old of male JTT sheep and paddock with field grass vegetation were used in the research. Fifteen male JTT sheeps were divided into three groups consisting of 5 heads per group, and grazing for 2 month (in early rainy season, late rainy season and dry season, respectively). The measured variables were feed consumption, digested organic matter, mineral (calcium, phosphorus, magnesium, copper, zinc) level in forage, feces, blood, and daily body weight gain. The data were analyzed by analysis of variance with one-way classification. Magnesium and zinc status of JTT sheep were adequate, whereas phosphorus status was deficient in all season. Calcium in early and late rainy season were deficient (7.37 and 7.86 mg/100 mL, respectively), whereas in the dry season was adequate (8.70 mg/100 mL). The copper deficiency was found in dry and late rainy season (with the Serum copper level was 0.62 and 0.51 µg/mL, respectively, and borderline in early rainy season (64.7 µg/mL). Serum copper in the late rainy season was lower (P<0.05) than it in early rainy season and dry season. There were seasonal variation of mineral status of Java thin-tailed (JTT) sheep grazed in Mijen agricultural area, Semarang, Central Java.
