    It has been shown that some adipocytokines and their mutual relationship can be indicators of fetal and neonatal growth. Physiological role of leptin and adiponectin in fetal and neonatal growth is not well established. Objectives. The aim of this study was to assess the correlation of the anthropometrics parameters and serum concentration of leptin and adiponectin levels in healthy newborns. Methods. A cohort of 110 neonates, born after uncomplicated singleton pregnancies at term, were classified as AGA (n=60), SGA (n=30) and LGA (n=20) according to the Lubchenco curves. Anthropometric parameters of the neonates: birth weight (BW), birth length (BL), body weight/body length ratio (BW/ BL), Body Mass Index (BMI) and Ponderal Index (PI) were recorded after birth. Results. Mean serum leptin and adiponectin levels in both sexes were not significantly different (male: 1.85±0.75; 29.51±22.89 and female: 2.06±0.99; 31.60±23.51 ng/mL). There was a significant difference between leptin levels in AGA and LGA newborns (1.93±0.84 vs. 3.12±1.50 ng/mL) (p<0.05), and in adiponectin levels between AGA and LGA compared to SGA newborns (32.8±23.29 and 43.40±31.24 vs. 12.67±2.43 ng/mL, respectively; p<0.05; p<0.05). Leptin and adiponectin levels were positively correlated with BW (r=0.63 and r=0.41), BL (r=0.63, r=0.42), BW/BL (r=0.61, r=0.41), BMI (r=0.54, r=0.35), and PI (r=0.47, r=0.29, (p<0.01). Conclusion. Significantly higher adiponectin levels were found in AGA neonates compared to SGA neonates. Leptin and adiponectine levels were positively correlated with birth weight. These findings suggest that these adipocytokines may be involved in fetal growth regulation.

    Financial effects from introduction of European egg marketing standards on the layer farms in R. Macedonia

    This paper presents the financial effects from introduction of the new EU method for grading the eggs according the size (weight) in 4 classes instead of Macedonian method of grading in 7 weight classes based on the comparative analyze of production records in three flocks of ISA commercial layers (Flock 1 - 18125, Flock 2 – 17587, Flock 3 - 16818). The comparison of the financial effects of the introduction of the EU grading system is made by the partial budgeting analysis. Application of European model for egg grading resulted in increased income of about 18-37 denars per average hen-day layer that improves the financial effects at the layer farms. Expressed per unit of production, egg grading based on the egg weight in 4 classes results in increased income per unit of production of 0.1-0.2 denars and is significant increase of the farm profitability knowing that each layer produces around 300 eggs during one production cycle of one year. Hence, the use of standards goes beyond marketing aspects, and can financially support the market without budgetary implications.
