AB - The effect of dietary containing different levels of steam treated pith on performance and carcass characteristics in growing Arabi lambs were investigated during a period of 10 weeks (70 days) using 40 lambs of 3 months old with an average live weight of 18.25 kg. The dietary treatments were 100% barley (diet 1), 75% barley + 25% pith (diet 2), 50% barley + 50% pith (diet 3) and 25% barley +75% pith (diet 4), respectively. The total pith contents of diets 1-4 were 0, 11, 22 and 33% (pith), respectively. The lambs were allocated to the diets (10 lambs diet-1) according to a completely randomized design. The diets formulated according NRC and had approximately, similar nutrients contents. Average Dry Matter Intake (DMI) of lambs fed diets 1-4 during whole period of experiment were 1400, 1441, 1389 and 1466 g day-1, respectively. Average Daily Gain (ADG) of lambs for diets 1-4 during whole period of experiment were 267±19.3, 307±18.8, 251±42.1 and 226±28.3 g day-1, respectively. Despite non significantly differences between ADG of control group with lambs fed diet 2 and 3, but lambs fed diet 4 had significantly (p<0.05) lower ADG than control group. The same trend was found for feed conversion ratio (F/G). Average F/G were 5.24±0.2, 4.7±0.2, 5.5±0.74 and 6.5±0.65, respectively for diets 1-4. The main carcass characteristics (composition and chops) were not affected by dietary treatments (p>0.05), but diet 2 had the best economic efficiency. This study suggests that lambs fed diet 3 had also better net return than control group, which is important for Iran condition. So, it is concluded that pith a by product of sugarcane has potential as an alternative feed source for ruminants, particularly for fattening lambs.
