Abstract
An experiment was conducted to study the nutritional value of jack (Artocarpus
heterophyllus) fruit residue silage in terms of chemical composition, intake, digestibility
and efficiency of utilization in lambs fed straw based diet. Twelve Mandya lambs of
about 3 to 6 months of age with body weight ranging from 8.5 to 10.3 kg were divided
into two groups of six each in a completely randomized design. Twelve weeks feeding
trial and six days digestion trial at 8th week was carried out. First group (T1) of lambs
were fed with finger millet straw as the sole source of roughage and compounded feed
mixture (CFM), while the second group (T2) were fed with jackfruit residue silage to
partially replace (25%) FMS as a source of roughage and CFM. Chemical analyses (%)
revealed that the JFRS has higher CP (8.77 v/s 3.35) and EE (1.91 v/s 0.79) and lower
TA (6.46 v/s 8.51), NDF (34.08 v/s 71.84), ADF (27.88 v/s 46.46) and ADL (1.06 v/s
3.83) contents as compared to FMS. Cumulative gas (ml / 200mg DM / 24 h) produ
