“…Parity least squares means for Ca and P (Table 2) followed a similar trend to that described by Kume et al (1998) in Japanese Holstein cows, who reported a slight decrease in milk mineral concentration after first parity, even if not statistically significant. The decrease in milk Ca and P content within increasing parity is probably due to the reduced Genetics of milk minerals and acidity utilization of these minerals in the mammary gland (Kume and Tanabe, 1993).…”

The aim of the present study was to estimate genetic parameters for calcium (Ca), phosphorus (P) and titratable acidity (TA) in bovine milk predicted by mid-IR spectroscopy (MIRS). Data consisted of 2458 Italian Holstein − Friesian cows sampled once in 220 farms. Information per sample on protein and fat percentage, pH and somatic cell count, as well as test-day milk yield, was also available. (Co)variance components were estimated using univariate and bivariate animal linear mixed models. Fixed effects considered in the analyses were herd of sampling, parity, lactation stage and a two-way interaction between parity and lactation stage; an additive genetic and residual term were included in the models as random effects. Estimates of heritability for Ca, P and TA were 0.10, 0.12 and 0.26, respectively. Positive moderate to strong phenotypic correlations (0.33 to 0.82) existed between Ca, P and TA, whereas phenotypic weak to moderate correlations (0.00 to 0.45) existed between these traits with both milk quality and yield. Moderate to strong genetic correlations (0.28 to 0.92) existed between Ca, P and TA, and between these predicted traits with both fat and protein percentage (0.35 to 0.91). The existence of heritable genetic variation for Ca, P and TA, coupled with the potential to predict these components for routine cow milk testing, imply that genetic gain in these traits is indeed possible.

“…The variation across calendar month for milk minerals might be due to the change in the diet of animals reared in the Alpine area, since a quite common practice in Alpine regions is to move cows to highland pastures during summer (June to September). Least squares means of Ca and P contents across parity (Figure 2) were consistent with the findings of Kume et al (1998), who reported the same decreasing trend in Holstein dairy cows. Indeed, it has been hypothesised that the utilisation of these minerals at the mammary gland level is lower in multiparous cows (Kume and Tanabe 1993).…”

Population-level phenotyping is, for some traits, hardly achievable due to limitation of reference analyses. Mid-infrared spectroscopy (MIRS) is a quick and cost-effective laboratory technique allowing the prediction of innovative milk quality features on a large scale. The present study aimed at investigating factors associated with milk Ca, K, Mg, Na and P contents predicted by MIRS models on a large multi-breed spectral data set of 123,240 test-day records. Two dairy (Holstein-Friesian and Brown Swiss) and two dual-purpose (Simmental and Alpine Grey) cattle breeds were considered. Sources of variation of predicted milk mineral contents were studied using linear mixed models, including the fixed effects of breed, month of sampling, stage of lactation, parity and interactions between the main effects. Random factors were herd nested within breed, cow nested within breed and the residual. Calcium content was greater in milk of dual-purpose than dairy cattle breeds. Simmental cows produced milk with the greatest content of Ca and Na, and milk of Holstein-Friesian had the lowest P content. Variation of content of Ca, Mg, Na and P throughout lactations exhibited an opposite trend to that of milk yield, with the lowest values around the peak of lactation. On the other hand, K content mirrored the trend of milk yield. Multiparous cows had lower content of milk minerals, with the exception of Na, compared with first parity animals. Environmental factors identified in the present study can be considered for within-breed genetic evaluation to adjust records of milk mineral contents for these effects. ARTICLE HISTORY

“…Before calving the iron parameters in the blood plasma of the cows was significantly higher compared to the concentration in the postnatal period below the reference values [Miltenburg et al 1991, Weiss et al 2010, Winnicka 2015. Kume et al [1998] indicate that reduced concentration of the iron just before calving may be associated with the transfer of iron for the hemoglobin synthesis, which concentration increases during this period. It has been shown that the concentration of iron in the serum may be decreased as a result of increased erythropoiesis and insufficient provision of the element with food.…”

Knowledge of the changes in the concentrations of biochemical parameters gives the possibility to conclude about the health status of the cows, the quality of nutrition, or reproductive performance and milk productivity. The studies aimed to assess the health status of the primiparous dairy cows at the time of prospectus new fertilization and to screen the challenges of the preceding periparturient period through the analysis of protein metabolism and iron parameters in context of their potential role as markers of the reproductive status. Despite significant variations, the studies showed that homeostatic mechanisms and adaptational processes in cows organism are rather efficient during this period. Nevertheless, it should be underlined that at the time of prospectus new pregnancy higher concentration of urea, lower concentration of creatinine and iron parameters was noted, emphasizing the dysregulation of the organism condition and pointing the possible reason of/association with prospectus difficulties in further reproductive performance. If analyzed for the particular herd, these parameters may be useful in considerations about the selection of the time for new fertilization.
