Total 12 lactating Osmanabadi goats were selected and divided into 3 groups T1, T2 and T3 of 4 goats in each. Three types of concentrate mixtures I, II and III were prepared using commonly available feed ingredients viz. maize, de-oiled rice bran, soybean meal, cotton seed cake, mineral mixture and salt. Jackfruit peel was added at the rate of 0, 10 and 20% level in the concentrate mixture I, II and III, respectively. The goats of group T1, T2 and T3 were fed concentrate mixture I, II and III, respectively at the rate of 350 g per day. Green roughage (Hybrid Napier fodder) was fed ad libitum to goats of each group. After an adaptation period of 21 days on experimental diet, goats were transferred to metabolic cages. Prior to conducting metabolic trial for a period of 5 days, the goats were kept in the cage for 3 days for adaptation. The proximate composition of JFP was dry matter (DM)- 68.73%, moisture 31.27%, crude protein (CP)- 6.28%, crude fat/ether extract (EE)- 2.76%, crude fibre (CF)- 17.19%, nitrogen free extract (NFE) 67.8% and total ash (TA)- 5.97%. Inclusion of JFP at different levels did not show any significant effect (P>0.05) on the intake, outgo (g/d) and digestibility (%) of dry matter, organic matter, crude protein, ether extract, nitrogen free extract, crude fibre and nitrogen retention (%) among the goats of different groups. The effect of dietary inclusion of jackfruit peel at different levels on Ca and P intake, excretion and on apparent absorption was non-significant. The effect of dietary inclusion of different levels of JFP on various haematological parameters viz. haemoglobin (g/dl), packed cell volume (%) and serum biochemical parameters viz. total protein, albumin, globulin (g/dl) and A:G ratio was found to be non-significant (P>0.05). Serum ALT level was not affected by JFP supplementation whereas, AST level was significantly different between control (90.34 IU/L) and 20% JFP (64.72 IU/L) supplemented diet, possibly due to improved antioxidative status in the JFP supplemented group. Inclusion of JFP at different levels did not show any significant (P>0.05) effect on total milk yield, fat corrected milk yield (ml/d) and percentage of milk fat, SNF, protein and lactose in different groups. Jackfruit peel could be incorporated up to 20% level in Osmanabadi goats feed with no adverse effect on nutrient utilization, haemato-biochemical parameters and milk profile. Inclusion of JFP was more economical compared to feeding of unsupplemented diet and There was a reduction in 15.88% and 14.79% feed cost per goat daily on supplementing JFP at 10% and 20% levels, respectively.EnglishThesis
