dc.description.abstractIn a completely randomized design (CRD), eighteen ram lambs (9-11 kg) of about 3-4 months age were randomly divided into three equal groups of six each and allotted to three dietary treatments (T1 to T3) comprising of green fodder viz., Super Napier and concentrate mixture. A concentrate mixture with 20% CP prepared by using conventional feed ingredients was used as a control (T1). In this concentrate mixture, cashew nut kernel meal was incorporated at 10 (T2) and 20 (T3) per cent level. All the concentrate mixtures were made iso-nitrogenous. All the three diets were evaluated for their effect on haematological parameters, serum biochemical profile, growth performance, nutrient digestibility, nutritive value, carcass characteristics and cost economics in ram lambs. The haematological parameters viz., Hb (g/dl), RBC (106/μl), WBC (103/μl), PCV (%) and MCV (fL); serum biochemical parameters viz., total protein (g/dl), albumin (g/dl), globulin (g/dl), glucose (mg/dl), triglycerides (mg/dl), cholesterol (mg/dl), AST (U/L), ALT (U/L), creatinine (mg/dl), urea (mg/dl), calcium (mg/dl) and phosphorus (mg/dl) were evaluated at the beginning and end of the experiment. The results revealed that there was no significant (P>0.05) difference observed between and within the treatments, and the values were within the normal range. The body weight gain and average daily gain increased (P0.05). The digestibility (%) of EE differed significantly (P0.05). The average DMI of ram lambs expressed as Kg/d or as % BW was comparable (P>0.05) among treatments. The DCP (%) increased with increasing levels of CNKM in diet of ram lambs but the differences were not significant (P>0.05). The TDN content expressed as % in diet consumed was higher (P0.05). The estimated DE and ME intakes (Mcal/d) increased (P0.05) on empty body weight, hot carcass weight, dressing percentage expressed on live weight and proportion of fore and hind saddle as percentage of hot carcass weight. But, dressing percentage expressed on % of empty body weight was higher in T3 compared to T1 but the differences between T1 and T2 and T2 and T3 were comparable. The proportion of whole sale cuts (% carcass weight) viz., brisket & fore shank, shoulder & neck, rack, loin and leg increased linearly with increased levels of CNKM in concentrate mixture, but the differences between treatments were non-significant (P>0.05). The yield of visceral organs expressed as per cent of pre slaughter weight did not vary significantly (P>0.05) among the treatments (T1, T2 and T3). Inclusion of CNKM increased (P<0.05) protein and fat and decreased (P<0.05) ash values compared to control in Longissimus dorsi muscle of ram lambs. Based on the above results, it was concluded that cashew nut kernel meal can be included up to 20% level in the concentrate mixture without any adverse effect on nutrient utilization in ram lambs.en_US
