    The present investigation is carried out to study the effect of dietary inclusion of cumin seed powder at varying levels on growth performance, serum biochemical profile, digestibility of nutrients, carcass characteristics and cost economics in Japanese quails. One hundred and fifty, day old quail chicks were distributed randomly to five dietary groups each with three replicates of ten chicks and were offered experimental diets to meet the nutrient requirements (NRC, 1994). During the experiment, cumin seed powder is included at 0.0% (T1: Control), 0.50% (T2), 1.0% (T3), 1.5% (T4) and 2.0% (T5) level by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous. Chemical analysis indicated that cumin seed powder contained 18.26% CP, 14.02% EE, 30.02% CF, 27.96% NFE, 7.79% TA and 0.42% AIA. Results indicated that body weight gain, PI (P0.05) on feed intake with increased level of inclusion of cumin seed powder from 0 to 2.0% in the diet. The serum biochemical profile of quails revealed that inclusion of cumin seed powder up to 2.0% in the diet had no effect (P>0.05) on serum total protein, albumin, globulin, AST, ALT, serum urea, calcium and phosphorus contents. However, the study indicated that the serum glucose, triglycerides, total cholesterol, LDL cholesterol, VLDL cholesterol and serum creatinine levels decreased (P0.05) on DM, OM, CP, EE and NFE digestibility as compared to the control. However, the digestibility coefficient of CF (P0.05) on weight of heart, liver, gizzard and giblet with increased level of inclusion of cumin seed powder from 0 to 2.0% in the diet. The feed cost / kg gain decreased by4.08 in T2 and7.69 in T3 while it is increased by2.70 in T4, and 8.70 in T5 groups of quails fed diets containing cumin seed powder at 0.5, 1.0, 1.5 and 2.0% levels in the diet as compared to the control. Thus, it is concluded that cumin seed powder can be included up to 1.0% level as natural feed additive in the diet without any adverse effect on production performance of Japanese quail.

    The present investigation is carried out to study the effect of supplementation of clove powder at different levels on growth performance, serum biochemical profile, digestibility of nutrients, carcass characteristics and cost economics in Japanese quails. One hundred and fifty, day old quail chicks were distributed randomly to five dietary groups each with three replicates of ten chicks and were offered experimental diets to meet the nutrient requirements (NRC, 1994). During the experiment, different levels of clove powder were added to the basal diet as follows: Basal diet (T1), basal diet + 0.25% clove powder (T2), basal diet + 0.5% clove powder (T3), basal diet + 0.75% clove powder (T4), basal diet + 1.0% clove powder (T5). Results indicated that supplementation of clove powder from 0 to 1.0% level in the diet had no effect (P>0.05) on body weight gain, feed intake, feed conversion ratio, performance index and protein efficiency ratio in quails as compared to the control. The serum biochemical profile of quails revealed that supplementation of clove powders up to 1.0% in the diet had no effect (P>0.05) on serum total protein, albumin, globulin, AST, ALT, serum urea, creatinine, calcium and phosphorus contents. However, the study indicated that the serum glucose, triglycerides, total cholesterol, LDL cholesterol and VLDL cholesterol levels decreased (P0.05) on CF digestibility. Further, supplementation of clove powders up to 1.0% in the diet had no effect (P>0.05) on carcass yield, dressing percentage, ready to cook yield and per cent weight of heart, liver, gizzard and giblet as compared to the control. The feed cost / kg gain decreased by1.68 in T2 while it is increased by 4.60 in T3, 9.24 in T4 and 14.29 in T5 groups of quails supplemented with clove powder at 0.25, 0.50, 0.75 and 1.0% levels in the diet as compared to the control. Thus, it is concluded that clove powder can be supplemented up to 0.25% level as feed additive in the diet without any adverse effect on production performance of Japanese quail.

    EFFECT OF DIETARY SUPPLEMENTATION OF CURRY LEAF (Murraya koenigii) POWDER AS NATURAL FEED ADDITIVE ON THE PERFORMANCE OF BROILER CHICKEN
    (SRI VENKATESWARA VETERINARY UNIVERSITY TIRUPATI - 517 502. (A.P.) INDIA, 2021-04) SRAVYA PRIYA, BEJJAM; Srinivas Kumar, D (MAJOR); Raja Kishore, K; Naga Raja Kumari, K
    The present study was carried out to study the effect of supplementation of curry leaf powder at different levels on growth performance, serum biochemical profile, digestibility of nutrients, carcass characteristics and cost economics in broilers. One hundred and fifty, day-old chicks distributed randomly to five dietary groups each with three replicates of ten chicks and were offered broiler diets to meet the nutrient requirements (BIS, 2007). During the experiment, curry leaf powder was supplemented to the basal diet in pre-starter, starter and finisher phases as follows: Basal diet (T1), BD + 0.5% curry leaf powder (T2), BD + 1.0% curry leaf powder (T3), BD + 1.5% curry leaf powder (T4) and BD + 2.0% curry leaf powder (T5). Results indicated that supplementation of curry leaf powder from 0.50 to 2.0% in the diet resulted in increased (P0.05) on overall feed intakes of birds. The serum biochemical profile of broilers revealed that supplementation of curry leaf powder up to 2.0% level in the diet had no effect (P>0.05) on serum albumin, globulin, HDL cholesterol, urea, creatinine, serum calcium and phosphorous content while it decreased significantly the serum total protein (P0.05) on digestibility of DM, OM, CP, EE and NFE while the CF digestibility decreased significantly (P0.05) on dressing percent, weight of head, shank, heart, liver, gizzard and giblets in broilers. The feed cost/kg gain decreased by ₹ 4.32 in T2, ₹ 4.61 in T3, ₹ 1.66 in T4 while it increased by ₹ 1.37 in T5 groups of broilers fed diets supplemented with curry leaf powder as compared to the control. Thus, the present study indicated that curry leaf powder can be supplemented up to 1.0% level in the diet of broilers for decreasing feed cost/kg gain without any adverse effect on production performance of broilers.

    EFFECT OF INCLUSION OF CASHEW NUT KERNEL MEAL AT VARYING LEVELS IN THE CONCENTRATE MIXTURE ON PERFORMANCE OF RAM LAMBS
    (SRI VENKATESWARA VETERINARY UNIVERSITY TIRUPATI - 517 502. (A.P.) INDIA, 2021-03) SRAVANI, BALAGA; Raja Kishore, K (MAJOR); Srinivas Kumar, D; Kalyana Chakravarthi, M
    In 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.
