摘要：

This study was evaluates the effect of body condition score (BCS) on leptin concentrations of Criollo goats under increased photoperiod in central Mexico (22 degrees N). Mature Criollo goats (n = 24) were assigned to one of 4 experimental groups according to their BCS: Excellent (n = 6), Good (n = 6), Regular (n = 6) and Poor (n = 6). Blood samples were collected in 5 random dates during the experimental period (Feb-Jun) and leptin levels were analyzed by RIA. BCS affected (p<0.0) serum leptin concentration in a direct and proportional way; the better the BCS the greater serum leptin concentration. Results should help to understand adaptation mechanisms exerted by goats facing a marginal nutritional support. The last could be of economic significance especially in criollo goats managed under semi-arid conditions, in which scenarios of restricted nutrition prevail.
