    A biological trial was conducted to evaluate the effect of dietary incorporation of Rapeseed meal (RSM) in diets of Japanese quail on growth performance, serum biochemical profile, carcass traits, sensory parameters and cost economics of Japanese quail. Day old Japanese quails (n=150) were distributed randomly into five treatment samples each with three replicates containing ten birds each and were maintained under uniform management conditions. Experimental diets were prepared with incorporation of RSM at 0% (T1: control diet), 10% (T2), 15% (T3) 17.5% (T4) and 20% (T5) levels by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous. Feed and water were provided ad libitum. The birds were housed in battery cages during the experiment period of 0-5 weeks. Chemical analysis indicated that RSM contained 93.78% DM, 91.61% OM, 41.80% CP, 1.14% EE, 13.31% CF, 35.79% NFE, 8.39% total ash and 1.97% AIA. The results of current study revealed that mean body weights, mean body weight gains, mean feed intake and FCR had no significant effect. Two birds per replicate and total of six birds per treatment were slaughtered at the end of fifth week and the blood samples were collected. Serum triglycerides and serum VLDL-C levels were significantly (p<0.01) decreased with increasing levels of RSM. But, serum total protein, serum albumin, globulin, albumin: globulin ratio, serum total cholesterol, serum HDL-C, serum LDL-C, SGOT, SGPT, serum calcium, serum phosphorus, serum glucose, BUN and creatinine levels were not affected by different levels of RSM. The carcass traits such as mean dressing percentage, mean carcass weight, mean per cent weights of heart, liver, gizzard and giblet of quails revealed that incorporation of RSM up to 20% level had no effect. The meat quality parameters such as pH, extract release volume (ERV) and water holding capacity (WHC) of meat of quails revealed that incorporation of RSM up to 20% level had no effect. In sensory evaluation of meat, mean scores for all the parameters like colour, juiciness, tenderness and overall acceptability of meat revealed that incorporation of RSM up to 20% level had no effect. The percent retention of organic matter (OM), crude fiber (CF) and nitrogen free extract (NFE) were not significantly affected. Whereas the percent retention of dry matter (DM), crude protein (CP) and ether extract (EE) were significantly (p<0.05) decreased with increasing levels of RSM up to 20% but did not show any significant effect up to 15%. The feed cost / kg gain was significantly lower (p<0.01) in quails fed with 20% RSM as compared with other treatment groups. The study indicated that the feed cost /kg gain were ₹ 126.31, 129.78, 122.94, 118.87 and 113.50 for T1, T2, T3, T4 and T5, respectively. It was concluded that RSM can safely be incorporated up to 20% level in the diet without any adverse effect on performance of quails.

    The present study was carried out to study the effect of dietary incorporation of Peppermint Leaf Powder (PLP) on performance of quails. For this purpose, one day old Japanese quails (n=150) were distributed randomly to five dietary groups each with three replicates of 10 birds each and were maintained under uniform management conditions. Experiment diets were prepared with incorporation of Peppermint Leaf Powder at 0% (T1: control), 0.75% (T2), 1.5% (T3), 2.25% (T4) and 3.0% (T5) levels by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous. Feed and water were provided adlibitum. The birds were housed in battery cages during the experiment period of 0-5 weeks. Daily weighed quantity of feed was offered, end of every week feed residue and body weights were taken and body weight gain (BWG) and feed conversion ratio (FCR) calculated Chemical analysis indicated that PLP contained 17.90% CP, 14.37% CF, 2.31 % EE, 0.04 % calcium and 0.32% total phosphorus. Significantly (p<0.05) higher body weights were observed in birds fed with PLP at the end of experiment. The body weight gain was significantly increased (p<0.05) with increasing levels of PLP. Lower feed intake was observed in birds fed with PLP with increasing levels of PLP. Whereas, significantly better (p<0.05) FCR was reported at 3.0% level of PLP inclusion. Two birds per replicate and total of six bird per treatment were slaughtered at the end of 5th week. Serum total protein, Serum albumin, globulin, albumin globulin ratio, serum SGOT, serum SGPT, serum calcium, serum phosphorus and serum BUN were not affected by level of PLP. But, serum total cholesterol, serum triglycerides (p<0.05) and serum creatinine (p<0.01) was significantly decreased with increasing levels of PLP. Serum HDL-C values were increased significantly (p<0.05) and serum LDL-C and serum VLDL-C values decrease significantly (p<0.01) with increase in PLP level in diet. The carcass traits like live weight, carcass weight and dressing percentage were significantly (p<0.05) increased with increasing levels of PLP. On other hand, incorporation of PLP from 0 to 3.0% in diet had no significant effect on liver, heart, gizzard and giblet weights. The meat quality parameter i.e., pH, extract release volume (ERV) and water holding capacity (WHC) of meat of quails revealed that incorporation of PLP up to 3.0% level had no effect. In sensory evaluation of meat, Mean scores of sensory evaluations for all the parameters (colour, flavour, juiciness, tenderness and overall acceptability) of meat were increased significantly (p<0.05) at 3.0% PLP when compared with the other treatment groups. The digestibility coefficients of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), nitrogen free extract (NFE) and crude fiber (CF) were significantly (p<0.05) increased with increasing levels of PLP up to 3%. There was no significant difference in feed cost per kg gain in quails fed with PLP as compared with control group. The study indicated that the feed cost per kg gain was ₹ 121.57 (T1), 119.48 (T2), 120.58 (T3), 119.40 (T4) and 118.01 (T5). But numerically 3% level incorporation had Rs.3.56/- lower feed cost/kg body weight gain than control. It is concluded that PLP can safely be incorporated up to 3.0% level in the diet without any adverse effect on performance of quails.

    (SRI VENKATESWARA VETERINARY UNIVERSITY TIRUPATI - 517 502. (A.P.) INDIA, 2022-03) HARISH, K; NarendraNath, D (MAJOR); Susmita, T; Srinivas Kumar, D
    A biological trial was conducted to evaluate the effect of dietary supplementation of Anise (Pimpinella anisum L.)seed powder in diets of Japanese quail on growth performance, serum biochemical profile, carcass traits, organoleptic characteristics and cost economics of Japanese quail. one-hundred-and-fifty day old Japanese quails were distributed randomly into five treatmentswith three replicates containing ten birds each and was fed with five experimental diets T1 (Basal diet), T2 (Basal diet with 0.5% Anise seed powder), T3 (Basal diet with 1.0% Anise seed powder), T4 (Basal diet with 1.5% Anise seed powder) and T5 (Basal diet with 2.0% Anise seed powder) from 0-5 weeks of age. The results of current study revealed that mean body weights were significantly (p<0.01) higher at 2nd, 3rd, 4th and 5th week in T3 (1.0% Anise seed powder) group compared to control group.The mean cumulative body weight gains were significantly (p<0.05) higher inT3 (1.0% Anise seed powder) when compared with the control. The serum total protein was significantly (p<0.01) increased in T3 (1.0%) when compared to control group and among treatment groups. Serum Albumin was significantly (p<0.01) increased in T3 (1.0%) and T4 (1.5%) compared to control group. Serum globulin was significantly (p<0.01) increased in T3 (1.0%) when compared with control group. Albumin globulin ratio was not influenced by supplementation of Anise seed powder. The serum total cholesterol and LDL cholesterol concentration were significantly (p<0.01) decreased in T3 (1.0%) compared to control group. The mean HDL concentration was significantly (p<0.05) increased in T3 (1.0%) compared to control group. No significant difference was observed in serum VLDL cholesterol, serum triglycerides, SGOT and SGPT among treatment groups. The carcass traits like dressingpercentage, weights of liver, heart and gizzard and giblet did not show any significant difference among the treatment groups. The organoleptic character scores for flavour, juiciness, tenderness and overall acceptability were improved significantly (p<0.01) in Anise seed powder fed groups when compared to the control. The highest scores recorded in T3 (1.0%). The feed cost per Kg gain was increased from T1 to T5 groups. The values ranged from Rs.117 to 139.22 with lowest value recorded in control. Hence, the current study revealed that the dietary supplementation of Anise seed in diets may not be economically feasible for producing Japanese quail meat. But, supplementation of Anise seed at 1.0% can be recommended for the production of designer meat with low cholesterol, increased HDL and better organoleptic characters.

    (SRI VENKATESWARA VETERINARY UNIVERSITY TIRUPATI - 517 502. (A.P.) INDIA, 2022-03) ANUSHA, PYDI; Narendra Nath, D (MAJOR); Tirupathi Reddy, E; Srinivas Kumar, D
    The present experiment was carried out to study the effect of dietary inclusion of Moringa leaf powder with and without enzyme on growth performance of Japanese quails. Day old Japanese quails (n=150) were distributed randomly into five dietary groups each with three replicates of 10 birds each and were maintained under uniform management conditions. Experimental diets were prepared with inclusion of Moringa leaf powder at 0% (T1: control), 3% without enzyme (T2), 3% with enzyme (T3), 6% without enzyme (T4) and 6% with enzyme (T5) levels by marginal adjustment of other feed ingredients. All the rations were made iso-caloric and iso-nitrogenous. Feed and water were provided ad libitum. The birds were housed in battery cages during the experiment period of 0-5 weeks. Chemical analysis indicated that MLP contained 93.56% DM, 23.60% CP, 14.37% CF, 8.65 % EE,14.98 % total ash,1.43% AIA, 3.28 % calcium and 0.45% total phosphorus. Study showed that the body weights and body weight gains were significantly (p0.05) among the treatment groups supplemented with 0 to 6 % MLP with and without enzyme. The digestibility coefficients of OM, EE and NFE were not significantly different (p>0.05) among different treatments. On the other hand, significantly higher digestibility of DM (p<0.05) and CP (p<0.01) were observed in group supplemented with 3% MLP with enzyme (T3) and significantly higher (p<0.05) digestibility of CF was observed in groups supplemented with 3 and 6% MLP with enzyme (T3 and T5). The present study indicated that the feed cost per kg gain was 110.72, 105.68, 101.97, 104.13 and 102.13 ₹, respectively for T1, T2, T3, T4 and T5, respectively. The lowest feed cost per kg live weight gain was observed in 3 % MLP with enzyme supplemented group (T3). Hence, MLP at 6 % with enzyme may be recommended in Japanese quail diet for better overall performance.
