“…Therefore, TDC reflects physiological changes in peripartum cows, and would more correctly interpret MPT results than STC. Adams et al [1] reported that the distribution of values for a given parameter is important for the interpretation of MPT. This study found that interpretation of MPT by distribution of values in TDC was effective for detection not only in a herd but also of individual abnormalities.…”

“…ten-day criteria (TDC) from dry off (60 days before calving) to calving and from calving to 300 DIM, the range of mean ± 1.0 SD for all MPT components was determined. For the control, stage criteria (STC) -mean ± 1.3 SD which is the practical and commonly used criterion [1,16], was also determined.…”

“…Subsequently, many researchers have applied MPT to improve feeding management [1, 2, 4-7, 10, 12, 13, 18, 25], detect subclinical health problems and prevent production diseases [1,6,12,16,18]. MPT, in conjunction with animal and facility evaluation, body condition scoring and ration evaluation, is an extremely useful tool for nutritional evaluation in dairy herds [22,23].…”

ABSTRACT. The traditional metabolic profile test cannot be applied to peripartum dairy cows, because these cows are in a state of physiological abnormality making it difficult to interpret their blood components. This study aimed at establishing and evaluating the practicability of interpreting a metabolic profile test every 10 days (Ten-day criteria) during the dry and lactation periods in herds with high and no incidence of peripartum diseases. Data from 29,043 cows in 1,130 commercial dairy herds were used to establish standard values every 10 days, mean ± 1.0 standard deviation for the metabolic profile test. The practicability of these criteria was evaluated in herds with peripartum diseases. In the ten-day criteria, the body condition score, albumin, blood urea nitrogen, glucose, total chole sterol, nonesterified fatty acids, γ-glutamyl transpeptidase and aspartate aminotransferase, fluctuated during the dry and early lactation periods and there were very big changes in packed cell volume, blood urea nitrogen, total cholesterol and magnesium just after calving. The tenday criteria were able to detect overconditioned cows, low levels of albumin, total cholesterol and magnesium, and high nonesterified fatty acids in herds with a high incidence of peripartum diseases. In conclusion, the ten-day criteria can be successfully applied to peripartum cows, and is recommended because it is able to detect metabolic abnormalities not only in the herd, but also in individual cows. KEY WORDS: criterion, dairy cow, metabolic profile test.

ABSTRACT. The aim of this study was to assess the practicality of the metabolic profile test (MPT) for feeding evaluation in dairy cattle.Stepwise regression analysis was used to evaluate the relationships of MPT to feeding and milk production of 4,679 cows in 343 commercial dairy herds. Significant explanatory variables were determined by forward set-up selection, among the deviated values from the reference values of 10 blood metabolites and body condition score, to predict dependent variables, i.e., milk production and the rate of feeding to nutrient requirements, in each or all lactation stages and the dry period. The milk production model of the all-lactation stage showed the greatest goodness-of-fit (adjusted R 2 =0.214, p<0.0001) with high positive regression coefficients for serum cholesterol, magnesium, urea nitrogen and albumin, and negative for glucose and calcium. In the feeding models, goodness-of-fit of crude protein was relatively high (R 2 =0.072, p<0.0001) with a positive relationship to blood urea nitrogen. Although the other feeding models were low in goodness-of-fit, several significant explanatory variables to feeding were found. All feeding models in the late lactation stage and the dry period, in which the feeding was stable, had greater goodness-of-fit than those in the early lactation stage in which milk production varied. It was concluded that the values which deviated from the reference values for the MPT components could assess milk production and feeding, and the MPT is a practical tool for auxiliary feeding evaluation. KEY WORDS: dairy cow, feeding and nutrition, metabolic profile test.

“…Subsequently, many researchers have applied MPT to improve feeding management, detect sub-clinical health problems and prevent production diseases [1,4,6,13,[15][16][17]24]. However, as it is not cost effective, MPT is not generally used as a tool for preventive medicine.…”

ABSTRACT. The aim of this study was to evaluate the practicability of using the metabolic profile test (MPT) as a preventive tool for periparturient disease of dairy cows. The MPT was assessed in 79 dairy herds with high incidence of periparturient disease and 76 healthy herds of cows producing more than 8,500 kg 305-day milk yield. The changes in metabolic profiles were also assessed in 17 dairy herds at two times, the first at high incidence of periparturient disease and the second after reduced incidence and improved feeding management. In the herds with high incidence of periparturient disease, low blood values of hematocrit, albumin, glucose, cholesterol, calcium and magnesium were observed in the dry period. These values correctly diagnosed malnutrition as the cause of periparturient diseases. Following feeding management changes, there was a low incidence of periparturient disease and the metabolic profiles were normal showing that feeding management had improved. We concluded that the MPT is a useful tool for assessing feeding management and periparturient diseases of dairy cows. KEY WORDS: dairy cow, metabolic profile test, periparturient disease.
