Evaluation substituting pasta waste with barley grains in fattening diet of Balouchi lambsand gas production test

Pasta Waste (PW) is commercially 40 to 50 per cent cheaper than barley. Moreover, Pasta Waste and barley grain have similar chemical composition. So the goal of present study was Substituting Pasta Waste with Barley Grains in Fattening diet of Balouchi lambs.
Materials and Two experiments were assigned so as to evaluate substitution pasta waste (PW) with barley grain. In the first study gas production parameters of barley grain, PW and fattening diets of the second study were examined. In the second study effects of barley substitution with PW (in range of 0, 50 and 100% ) ondry mater intake (DMI), daily weight gain, apparent feed digestion and blood parameters were evaluated. 18 Baluchi male lambs (28.5±1 kg) with 5 to 6 month age were assigned randomly to three experimental fattening diets differing in PW ratio in a completely randomized design for 90 days.
The average of gas production from fermentable fraction (b) in PW was significantly higher than barley grain (P Present study result showed that in sito gas production of pasta wastes was higher than barley grain. Moreover, substitution of pasta wastes with barley grain had no negative effects on Balouchi lambs performance and reduced considerably feed cost and daily weight gain costs. So pasta wastes can use effectively in fattening lamb diets.
