In order to evaluate the effect of levels of supplementation with concentrate containing 25 % CP and 3.18 Mcal kg-1 MS-1 for feeder lambs on pasture in private about the weight and performance in different ages, the onset of puberty and reproductive performance, 21 Suffolk lambs were used, divided into three batches, with and without supplementation, fed from birth to weaning with two levels of intake of concentrate (300 and 600 g-1 day) given once a day with the daily record of leftovers. The lambs were identified, weighed at birth and every 30 days and were weaned at 60 days. There was no significant difference in weight and average daily weight gain at 30 days old. The weight and average daily weight gain were influenced by the level of food supplementation. The lot with the consumption of 600g showed superior performance to the other lots at 60 and 120 days old. For lots of 300 grams or without supplementation there was no difference for the parameters analyzed. The availability of 600 g per day of concentrate for lambs until weaning promoted greater average daily weight gain at 60 and 120 days of life and better reproductive performance in the second year of copulation.

Orchiepididymitis is the inflammation of both, testis and epididymis and may be caused by microbial agents such as Brucella ovis. Thus, the aim of the present report is to present a case of orchiepididymitis in a Lacaune ram with unilateral testicular enlargement. Ultrasonography of the testis revealed the presence of a circular hypoechogenic structure adjacent to the testicular parenchyma. Corynebacterium sp was isolated from the surgically removed testis. Two months after removal of the affected testis, the animal returned to the Veterinary Hospital due to an enlargement of the remaining testis. A new ultrasonographic exam revealed the presence of abscesses in the testicular parenchyma and periorchitis. After orchiectomy, Proteus mirabilis was isolated from the material.
