In a multiplier PIC farm were effectuated complex surveys in order to monitor the health of suckling piglets and of lactating sows, by centering recorded data from the actual situation on field and the correlative analysis of glycemia and body weight level of 18 lots of newborn piglets (n=167) respectively the glycemia of the sows. The testing of glycemia was done using Accu-Chek Active glucometre, utilizing drops of freshly sampled blood, by sectioning the tip of the newborn piglets’ tail, respectively by puncturing the pinna of sows. The inquires also included the taking of biometric measurements, consisting of individual weightings of piglets at the moment of parturition and at the moment of weaning. The data obtained on pairs: lot of suckling piglets – lactating sow were statistically analyzed using the Categorial analysis system ANOVA (Unpaired t test for Probability index calculation ”P” and linear regression analysis to calculate the Pearson correlation coefficient "r" and for determination of "r2"). Statistical analysis of recorded data from the sample of newborn piglets revealed high average values of glycemia in first hours after parturition (97.329±10.499 mg/dl), having a rising trend (107.01±7.378 mg/dl) in the next 10-15 hours, in terms of weights between 1.8 and 2.1 kg/piglet. It should also be noted that the piglets have reached an average weight of 7.3 kg at weaning, achieving an average gain of 5.5 kg during the lactation period (21 days). At newborn piglets, glycemia levels increased significantly statistically (p = 0.003) after the first suckling and were positively correlated (r = 0.4945) with the values of their weight at parturition. Noteworthy is the insurance statistics (p = 0.001) of weight gain of the lots of piglets in interval between parturition and weaning (growth spore). According to these correlations, elevated glucose levels can be associated with the weight gain of newborn piglets. Less interesting proved to be the results obtained by monitoring the glycemia of mother sows, who have variations between 50 and 133 mg/dl, with insignificant deviations to physiological ranges of species and category (66-116 mg/dl).
