We opted for closed animal handling, and the trial was performed in the animal house of origin, under a forced exhaust ventilation system, with periods of natural luminescence, mean temperature of 20ºC, minimum noise, and humidity of around 50%. The animals were kept in appropriate cages with an area of 0.64 m2; they had no contact with their natural secretions. The diet consisted of water and granulated commercial diet (Purina® for rabbits—15% crude protein, 2.5% ethereal extract, 16% fiber material, 10% ash, 2.5% calcium, 0.42% phosphorus, 13% humidity, 31.58% carbohydrates) given ad libitum before and during the experiment.
