A 65-day study was undertaken to test the effects of two doses (10 and 20 mg/kg) of dietary fumonisin Bs (FB) on the rabbit male reproduction system. Body and testicular weight was not affected by the intoxication, neither the fatty acid composition of the testicular total phospholipids; the testis histological analysis failed to reveal any toxic effect. The FBs increased the testicular concentration and activity of reduced glutathione and glutathione peroxidase and decreased initial phase lipid peroxidation (conjugated dienes and trienes) in a dose dependent manner. Sperm morphology and chromatin condensation were monitored on Feulgen-stained smears. No significant differences were observed between the treatment groups and between sampling time points. The live cell ratio in the sperm (as assessed with flow cytometry) was not different among groups at any of the five sampling timepoints and was also identical within groups. Similarly, the spermatozoa membrane lipid profile was also identical in all three groups after the total intoxication period. In summary, it was demonstrated that FBs in an unrealistic and unjustified high dose still do not exert any drastic harmful effect on the leporine, male reproduction system, meanwhile slightly augmenting testicular antioxidant response.

Keeping and feeding of companion carnivores (dogs and cats) appear to be a simple activity for a shallow observer. By a multidimensional approach, all three domains of health can be analysed in the course of pet-feeding. The interest of animal health requires healthy, nutritious, and non-infectious pet food. At the same time, public health necessitates safety for pet owners and their families. By going much deeper, the environmental impacts of pets and pet foods can be identified. This review gathers the animal and human health and environmental aspects of domestic carnivore feeding. Based on the literature, it can be claimed that for the present, few data are available to determine the right way of feeding to reach the balance between all three domains of health.
