Sixteen half blood Schwyz x Guzera calves varying from fifteen to thirty days of age were randomized in two treatments; premunition and control. The treatments were composed by four animals of each sex. The results demonstrated significant difference between sex (P < 0,05), due to premunition, being the treated males significantly superior to non treated.
