Popis: Βασικός σκοπός της εργασίας αυτής ήταν ο προσδιορισμός των συγκεντρώσεων βιταμίνης Α και καροτενίων στο πλάσμα αίματος και στο ήπαρ βοοειδών που σφάχθηκαν στο νομό Θεσσαλονίκης. Για το σκοπό αυτό, δειγματίστηκαν 165 βοοειδή που προσκομίστηκαν στα διάφορα σφαγεία του νομού Θεσ/νίκης, το χειμώνα του 1998. Από κάθε ζώο λήφθηκε δείγμα αίματος και ήπατος. Από τα 165 βοοειδή, ποσοστό 76% είχε πενικές συγκεντρώσεις βιταμίνης Α ήπατος [4,8 μg/ml πλάσματος) πιθανόν να οδηγούν σε δυσλειτουργία των ωοθηκών.
The purpose of this survey was the study of vitamin A concentrations in cattle to be slaughtered in the area of Thessaloniki. For this purpose, research samples of blood and liver were collected from 165 cattle brought to different slaughter-houses of Thessaloniki, during the winter of the year 1998. Out of the 165 cattle to be slaughtered 76% presented lower than normal vitamin A in liver tissue (< 60 Mg/g W.M.), 14% had marginal (60-200 pg/g W.M.) and 10% normal concentration values (200-800 μg/g W.M.). It must be noted that, of the total 205 examined cattle 37% presented extremely deficient concentration of vitamin A in liver (< 14 μg/g W.M.), in these concentrations clinical signs of avitaminosis A are expected to appear. The statistic analysis of the research results show off that the liver and plasma concentrations of vitamin A were statistically significant lower in the fattening cattle (male and female) than in the adult reproductive cows. Statistically significant differences on liver and plasma vitamin A concentrations between male and female fattening cattle were not found. Statistically analysing this research it is confirmed for another time, that there is not closed linear relation between the vitamin A plasma concentrations and vitamin A liver concentrations. The linear regression equation that has been found between the vitamin A liver concentration (X) and the vitamin A plasma concentration (Y) is: Y=0,183+0,001 (±0,000***) X (***P4,8 μg/ml of plasma) for a long term may cause ovary dysfunction.
