Sixteen male Nali lambs (7–8 months, 15–16 kg BW) divided into 4 equal groups in a randomized block design were fed isonitrogenous and isocaloric rations in 4 different treatments viz. T1: control, containing cotton seed cake (CSC), T2: CSC replaced by mustard oil cake (MOC) on protein basis, T3: CSC replaced by 1% formaldehyde (HCHO) treated MOC, and T4: CSC replaced by 1% HCHO treated MOC and wheat bran (WB) by bakery waste on protein basis along with sewan (Lasirus sindicus) hay for a period of 120 days. At the end of growth trial, a metabolism trial of seven days was conducted to know the digestibility of nutrients. The digestibility of dry matter (DM) and proximate principles were similar in four treatments. Palatability score in terms of DM intake per 100 kg body weight and per kg W0.75 was significantly (P<0.01) lower in T3 and T4 in comparison to T1 and T2. Feed efficiency in terms of weight gain and wool production was significantly (P<0.05) higher in T3 and T4 in comparison to T1 and T2. The average body weight gain of lambs in T3 and T4 was significantly (P<0.05) higher than T1 and T2 with an average daily gain of 76.9±2.59, 57.8±4.11, 120.0±3.13 and 102.2±2.26 g in T1, T2, T3 and T4 groups, respectively. All the animals were in positive nitrogen, calcium and phosphorus balance. Significantly (P<0.05) higher nitrogen balance and blood urea nitrogen was observed in T3 and T4 in comparison to other groups. Highly significant (P<0.01) effect of treatment on greasy fleece weight and clean wool yield indicated better performance of T3 and T4 groups. Results indicated adequate scope for replacement of CSC by 1% HCHO treated MOC and WB by bakery waste in the ration of lambs without any adverse effect on growth, digestibility of nutrients and wool production in sheep.
