Evaluation of Poultry Droppings Based Concentrate mixtures For Ruminants by In Vitro Method

The study was planned to ascertain the effect of inclusion of dried poultry droppings (PD) at graded levels on chemical composition, in vitro utilization and degradability of concentrate mixtures. Dried poultry Droppings were added @ 0,5,10,15,20 and 25% in various concentrate mixtures. In vitro utilization of concentrates having dried poultry droppings (PD)@ 10 &20% showed a significant increase (P<0.05) in Net gas production (NGP), Organic matter digestibility (OMD%), Dry matter digestibility (DMD%), Metabolisable energy (ME), Neutral detergent digestibility (NDFD %), Microbial mass Production (MMP) and partition Factor (PF). At 72 h incubation time, cumulative gas production (ml) in 5% poultry droppings-based concentrates was signiûcantly (P < 0.05) lower than those of 15 and 20 % poultry droppings based concentrates. The maximum rate of degradation (k) was observed in control concentrate (9.16%/h) and lowest in 25% poultry droppings based concentrate (7.46%/h). The value of “ b” (gas production from insoluble fraction was lowest in 5% poultry droppings based concentrate (30.92 ml) and was highest in 15% poultry droppings concentrate (39.29 ml). and in control (39.5). On the basis of above results it can be concluded that dried poultry droppings can be included upto 20% in concentrate mixtures for cost-efficient livestock production.
