ThesisItem Open Access COMPARATIVE EVALUATION OF THE EFFICIENCY OF UTILIZATION OF FINGER MILLET (Eleusine coracana) STRAW AND ARECA SHEATH (Areca catechu) BASED EXTRUDED COMPLETE FEED IN MANDYA LAMBS.(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, NANDINAGAR, BIDAR, 2022) SANJAY, G. C.; UMASHANKAR, B. C.The present study was conducted for comparative evaluation of the efficiency of utilization of the finger millet (Eleusine coracana) straw and areca sheath (Areca catechu) based extruded complete feed in Mandya lambs. Sixteen Mandya / Bannur lambs of about 3 to 4 months of age with body weight ranging from 7.8 to 12.9 kg were divided into two groups of eight each in a completely randomized design. Twelve weeks feeding trial was carried out with an initial adjustment period of two weeks and six days digestion trial in the 11th week of the experiment. The animals were randomly assigned to one of the treatment groups viz. T1 (Experimental group one; finger millet straw based extruded complete feed) and T2 (Experimental group two; areca sheath based extruded complete feed). Chemical analyses (%) revealed that, areca sheath was comparable with finger millet straw except for lower CP, ADF and ADL (3.29 v/s 4.79; 52.63 v/s 54.43; 3.52 v/s 5.66) and higher NDF (76.66 v/s 71.61) contents. Similarly, the composition of areca sheath based extruded complete feed was also comparable with finger millet straw extruded complete feed except for lower CP and ADL (14.14 v/s 15.32; 2.8 v/s 4.9) and higher NDF and ADF (61.03 v/s 59.16; 25.52 v/s 22.15) contents. Cumulative gas (ml / 200mg DM / 24 h) production and energy density (ME MJ / kg DM) was higher in areca sheath (38.44 & 7.63) as compared to finger millet straw (32.56 & 6.92). There was a significant (P≤0.05) difference in total DMI (as g per day and gram per kg metabolic body weight) between the two treatment groups (T1; 433 & 64.9 and T2; 402 & 60.4). However, there was significant (P≤0.05) difference in CP, OM and NDF intake. The ADG (g per day) and FCR (g DMI / g BW gain) for T1 and T2 groups were statistically non-significant (T1: 68.53 & 6.23 and T2: 65.58 & 6.06). The mean apparent digestibility (%) of nutrients (DM, OM, CP, NDF and ADF) and the per cent DOMDM was higher in AS ECF group (T2; 76.13) than FMS ECF group (T1; 70.89). It was concluded that the areca sheath could completely substitute the conventional finger millet straw, as a source of roughage for feeding growing lambs.
