Abstract

Twelve male lambs weighing 9,5 ± 0,4 kg were used to evaluate the use of sunflower silage as a roughage source in the sheep diet. Two treatments were used with six animals each. All received 300g/animal/day concentrate and sunflower or corn silage ad libitium depending on the treatment. Feed intake per group was controlled every three days and animals weighed every 15 days. The lambs were slaughtered 90 days after housed individually and the following traits measured: live weight, hot carcass weight, half carcass weight, carcass length, fat cover, skin (thickness and weight), leg, back, shoulder, rib, underbelly, neck, kidneys, liver, heart and lungs. The 12th rib was removed for later analysis. No significant differences were found between the two treatments in terms of weight gain or feed conversion. With the exception of fat cover, which was greater for lambs fed sunflower (p<0,05), no significant differences for carcass traits and 12th rib analysis were found between the two treatments. Sunflower silage can be used as an alternative source of roughage in lamb diet, obtaining similar results to corn silage.
