Abstract

The experiment was conducted on 9 draught Camels (8-9 years old of 572 ± 10.18 Kg. BW) to study the effect of energy supplementation fed Groundnut straw based diets on nutrient utilization, draught performance and physiological responses of draught camels. The randomly selected camels divided into three equal groups were offered ad lib Groundnut straw supplemented with either low energy (65% TDN) in concentrate (T₁), medium energy (70% TDN ) in concentrates ( T₂), or high energy (75% TDN) concentrates (T₃). The mean DMI was higher (P<0.05) in T₃ as compared to T₂ and T₁ groups. But a non significant difference was observed between T₂ and T₁ groups. The voluntary water intake (VMI), DCP and TDN intake was significantly (P<0.05) higher in T₃ and T₂ as compared to T₁. There was a significant difference between T₁, T₂ and T₃ for DCPI and TDNI. The digestibility of DM, CP and NFE was significant (P<0.05) in Camels fed 75% TDN concentrate mixture but there was non-significant difference between the treatment for digestibility of OM, CF and EE. While was a significant (P<0.05) Improvement in DCP and TDN contents in T₃ as compared to T₁ was observed. The DE and ME contents did not differ significantly among the groups. The draught (kgf) and power output (hp) was higher (P<0.05) in T₃ as compared to other treatment group. The values of pulse rate, respiration rate and rectal temperature were found to increase with increase in draught and duration of carting. The maximum variation in physiological responses was noted at 22 percent draught. However, increase in rectal temperature did not show any remarkable effect at higher draughts. It was concluded that ad lib feeding of groundnut straw supplemented with high energy concentrates mixture resulted in improved nutrient utilization and draught performance by the camels without any apparent ill effect on the health.
