Abstract

Twenty one Marwari, Patanwadi and Merino X Patanwadi weaner lambs (12.40 to 14.68 kg) were
randomly divided into three dietary treatments on body weight basis viz T1 : TMR I-Conventional
group (Maize- 22%, Ground nut cake- 15%, Rice polish- 15%, molasses- 10%, mineral mixture- 3%and urea treated wheat straw- 35 %), T2 : TMR-II supplemented non conventional group I (Azolla-10%, P J Pods -15 %, Corn steep liquor -12 %, Rice Polish- 10 %, G N Cake- 5 %, molasses- 10%,mineral mixture- 3% and urea treated wheat straw- 35 %) and T3 : TMR-III supplemented nonconventional group II (Azolla-20%, P J Pods -17 %, Corn steep liquor -15 %, molasses- 10%, mineral
mixture- 3% and urea treated wheat straw- 35 %). The average final body weight at the end of the
experiment was recorded 25.24 ± 1.96, 23.51 ± 1.36 and 21.07 ± 1.12 kg in TMR-I, TMR-II and
TMR-III, respectively. The treatment groups did not differ from each other. The body weight gain
and body measurements were significantly (P0.05) influenced by the treatments. The dr matter
intake (kg /head) during the entire experimental period was recorded 85.37 ± 19.10, 90.86 ± 4.30
and 81.02 ± 6.09 in TMR-I, TMR-II and TMR-III which differed (P<0.05) significantly. The DM and
CP digestibility was significantly (P0.05) affected by the treatments. Th digestible crude protein
(DCP) and total digestible nutrient (TDN) intake/head under TMR-I, TMR-II and TMR-III group did
not differ from each other. The estimated total feed cost (Rs./animal) for experimental lambs was thelowest (P0.05) in TMR-III (256.96 ± 16.42) followed by TMR-II (352.50 ± 22.06) and TMR-I (623.55).The return as percnt of feed cost and feed cost Rs. /kg dressed weight were 150.12 ± 2.46 and 67.01± 0.86, 198.59 ± 6.44 and 52.46 ± 1.64 and 213.57 ± 9.31and 51.04 in TMR-I, TMR-II and TMRIII,respectively which is the reflection of significantly (P<0.05) lower total feed cost incurred in nonconventional groups. Lambs fed non conventional based TMR had similar live weights as those fedconventional TMR but costed less to achieve those weights.
