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 […]

This study evaluated the effects of different dietary ratios of forage sorghum (Sorghum bicolor L) hay (FSH) to silk flower hay (Calotropis procera SW) (SFH) on true, biological, and retail carcass yields, carcass cooling losses, retail cut yields, tissue composition and carcass muscularity of Santa Inês lambs. Twenty-four intact male lambs were assigned to one of the following four treatments: 100:0 FSH:SFH, 66:33 FSH:SFH , 33:66 FSH:SFH, or 0:100 FSH:SFH in a completely randomized design (six animals/treatment). Animals were slaughtered […]
