It was evaluated four levels of silk flower (Calotropis procera S.W.) hay (SFH) as a substitute of sorghum (Sorghum bicolor) hay (SBH) in diet for lambs. Nutritional value of silk-flower hay was determined based on aparent digestibility and on metabolic, productive and economical performance of Santa Inês lambs. It was used twenty-four castrated males at 15.72 ± 1.92 kg body weight randomly distributed in four diets with silk-fklower and sorghum hay ratios (100:0, 66:33, 33:66, 0:100), and supplemented with a concentrate mixture based on 50% roughage:50% concentrate (weight/weight). Increase in the levels of silk-flower hay in the diet reduced weight gain and nutrient intake and it increased feed conversion and digestibility coeficients of all the nutrients. Nitrogen balance was similar in all levels of silk-flower hay, although there was a tendency of reduction in nitrogen retention at levels 66% and 100% of silk-flower hay. At the levels 0 and 33% of silk-flower hay in the diet, dry matter ingestion (170 and 180 g/day), daily average weight gain (84 and 89 g/kg0.75)and feed conversion (4.99 and 5.02) were satisfactory. Silk-flower hay can represent up to 16.5% of the total food ingestion or 33% of the roughage in diet for lambs.
