SUMMARY
The broccoli crop residue was analzsed for proximate nutrients, cell wall constituents and mineral and its feeding value was asseseed in goats in the Dept. of Animal Nutrition.The crop residue on DM basis contained 94.22 per cent organic matter, 27.20 per cent crude protein, 5.12 per cent crude fat, 7.99 per cent crude fibre and 53.91 per cent nitrogen free extracts. The crop residue contained 4.47 per cent calcium and 0.45 per cent phosphorus. A feeding trial of 15 days was conducted on five nonlactating Beetal goats (average body weight 24 kg) after which a metabolism trial of seven days duration was also conducted to assess the nutrients digestibility and balance of nutrients. Animals were maintained on fresh chaffed broccoli plant residue as a sole feed. The total dry matter intake of experimental goats was 624.4 ± 39.9 g/day which was worked out to be 2.67 per cent of body weight. Thus, broccoli was highly palatable to the goats but its consumption was limited due to high moisture content. The digestibility coefficients (%) of different proximate nutrients i. e. DM, OM, CP, EE, CF and NFE were 83.7±0.65, 84.04± 0.62, 87.84± 0.53, 87.08± 0.31, 69.64± 0.99 and 83.84± 0.78, respectively. It was found to contain 23.96 per cent DCP and 87.20 per cent TDN. All the animals maintained their body weight and were in positive nitrogen, calcium and phosphorus balance. The results of the study showed that broccoli crop residue was a very nutritious fodder and it could be utilized as a sole feed for small ruminants.
