Aim:The objective of this study was to evaluate the changes in hemato-biochemical indices in male and female Vanaraja chickens under tropical environment during summer and winter season.Materials and Methods:A total of 120 day-old sexed Vanaraja chicks were selected as experimental chickens and distributed equally in two groups having 60 female and 60 male chickens in each group, respectively. The experiment was continued for 8 weeks (56 days) and both male and female chickens were slaughtered by cervical dislocation method. All parameters were estimated at the end of the experiment in both seasons.Results:Male had higher blood glucose, Ca and P level. Blood glucose level significantly (p<0.05) reduced in summer. Female had higher total protein, albumin, globulin, and albumin/globulin ratio. Alanine aminotransferase and aspartate aminotransferase enzyme concentration were significantly (p<0.05) higher in summer. Total erythrocyte count, total leukocyte count, hemoglobin (Hb), Hb/lymphocyte ratio, and packed cell volume were significantly (p<0.05) higher in males. Mean corpuscular volume and mean corpuscular Hb were significantly (p<0.05) higher in females.Conclusion:Sex of chickens had a significant (p<0.05) effect on different parameters whereas season had nonsignificant (p>0.05) effect in most of the observed parameters. Hence, Vanaraja chickens are adaptable to local tropical climate and can be reared efficiently as backyard poultry.

To study the effect of different stocking density on the performance of White Pekin ducks, 144 unsexed day-old White Pekin ducklings were reared for 42 days and on 43rd day, these duckings were distributed into four equal groups, each with three replicates in deep litter system of rearing. The floor space provided per ducking was G1 : 1,350 cm2, G2 : 1,800 cm2 , G3 : 2,250 cm2 and G4 : 2,700 cm2. The experiment continued from 7-10th weeks of age. The parameters studied were body weight, body weight gain, feed consumption, feed conversion ratio (FCR), serum biochemical profile, carcass characteristics and litter moisture content. The 7th and 8th week body weight gain of all the treated groups did not differ significantly but higher body weight of ducks were recorded in G3 and G4 groups than that of G1 and G2 groups at 9th and 10th week of age. The cumulative (7-10 weeks) body weight gain and FCR of white Pekin ducks was higher in group G3 and G4 than that of G1 and G2 groups. Cumulative feed consumption of all the treated groups of ducks did not differ significantly. No significant difference was observed in the studied serum biochemical and carcass characteristics of the treated groups. The litter moisture content was lower in G3 and G4 than that of G1 and G2 groups in all the studied periods. From this, it may be concluded that the floor space of 1,350 cm2 up to 8th week and 2,250 cm2 at 9th and 10th weeks of age per Pekin duck is suitable with respect to production performance of birds.

Present work was carried out in the Ganjam Field Unit of AICRP on Goat improvement, Odisha to study the effect of deworming regimen on helminths and growth performances in growing Ganjam goats. It was found that deworming by using Ivermectin and Fenbendazole or Oxyclozanide and Levamisole preparation has got a significant effect on Ganjam kids with respect to body weight gain, haemoglobin, serum total protein, albumin and parasitic load. The effect of Ivermectin and Fenbendazole combination was found to be superior over Oxyclozanide and Levamisole combination on growth rate, helminthic infestation in terms of parasitic load and FECRT value. A negative correlation was observed between Hb% and PCV% with the mean parasitic load. Effect of deworming regimen was found to be non-significant at 2 or 3 months intervals using different anthelmintics with respect to parasitic load and growth performance. The deworming against helminths at an interval of 3 months is equally effective, economic and labour saving compared to 2 months.
