Histomorphology of Liver, Testicle and Body Fat in Farm Rabbits Fed with an Obesogenic Diet During the Peripuberal Period
Two groups were formed in order to evaluate the effect of an obesogenic diet on body and liver weight, body fat accumulation and the histometric characteristics of liver and testicles of New Zealand rabbits during the peripuberal period. One group received a standard farm diet and the other received...

Tissue samples were obtained from liver and testicles to carry out histometric analysis. Body weight, body mass index, liver and visceral fat weight were significantly different (P<0.01) in the obesogenic diet when compared to the control group. Notwithstanding, there were no significant differences between both groups in testicular weight, and scapular and scrotal fat (P>0.01).
