An experiment was conducted for nutritional evaluation of arhar (pigeon pea) straw. Twelve cattle (150-200 kg) divided into 2 equal groups were offered treatments viz. T1 (control) having concentrate mixture (45%) + wheat straw (55%) and T2 (Treatment): concentrate mixture (30) + arhar straw (70). The growing cattle were fed as per ICAR (1998) feeding standards to meet their nutrient requirements in terms of DM, DCP and TDN. The DMI on% basis and CP intake was comparable (P>0.05) between treatment T1 and T2 while DMI on kg/kg W0.75 and kg/day was higher (P<0.05) in T2 than T1 similarly DCP and TDN intakes were (P<0.05) higher in T2. The total and average daily gain were significantly higher (P<0.05) in T2 than T1. The digestibility of CP were significantly (P<0.05) higher in T2 than T1 while digestibility of other nutrients (DM, OM, EE and CF) was comparatively higher (P>0.05) in T2 than T1. The average values of NH3-N, total-N and protein-N concentrations in rumen liquor under T2 were higher as compared to T1 while TVFA content was similar between the groups. The efficiency of feed utilization was also superior in T2 than T1.The daily cost of feeding was Rs 48.80 and 42.66, while the cost of feeding (Rs/kg gain) was 108.27 and 76.94, respectively in T1 and T2 group.
