ABSTRACT
In this research the blood levels of leptin, GH and glucose and its correlations with body weight,
during the development of 20 Sardinian goat kids, was studied, from weaning up to the age of seven
months. Blood levels of leptin and GH showed an increase (P<0.01) in relation to the rise of the
animal’s body weight and a decrease upon reaching 28 kg. Leptin was found to positively correlate
with GH and glucose and negatively correlate with weight. The variations of leptin ratios and their
correlation with GH indicate an involvement of the lipidic hormone in regulating metabolism during
development.
