- Abstract
In this study, change of IGF-I in lactation period was investigated on 11 heads female white goat (6 heads 2 aged and 5 heads 3 aged) raised at the farm of Department of Animal Science, Faculty of Agriculture, Ankara University, Turkey. To determine IGF-I concentrations, the blood samples were regularly taken from jugular vein of goats in every two weeks during lactation period. The blood samples were centrifuged at 4000xg for 5 min. and serum was stored at -20 °C until analysis time. IGF-I analysis in the blood serum were performed by enzyme immunoassay (EIA) method. Climatic values of the experimental period were obtained from the local meteorological service and the temperature-humidity index (THI) was calculated. In the study, the observed IGF-I concentrations with respect to periods and age groups was analyzed by the repeated measures of ANOVA analysis. Significant differences (P<0.01) were found among the periods for IGF-I concentrations. In conclusion IGF-I concentrations were significantly influenced by photoperiod changes and IGF-I releases were depend on increased length of day during lactation period in White goats.
