Publisher: 1999Dissertation note: The study was designed to compare the efficacy of different feed additive anticoccidials and coccidiosis vaccines A total of 240 day-old-broiler chicks were purchased and raised for 42 days in good husbandry and hygienic conditions. The birds were randomly divided into eight groups i.e. A, B, C, D, E, F, G and H Comprising of 30 birds each. Groups A was uninfected unmedicated control while group B was infected unmedicated control. Groups C, D, E and F were given commercial feed having anticoccidials Coxistac, Sacox, Elancoban and Avatec respectively. Groups G and H were given unmedicated feed and were vaccinated at day 3 and 10. All the groups except that of group A were given primary and challenge doses of infection on day 22nd and 35th . The oocysts count was done on 5th 6th and 7th day after each infection. The feed consumption and weight gain were recorded weekly. Record of mortality was kept and postmortem of dead birds was also performed. The data collected was subjected to statistical analysis using Two Way Analysis of Variance and Least Significant Difference (LSD) test, to detect the differences between treatments and means.
It was concluded that Sacox (salinomycin sodium) as anti-coccidial in feed revealed significant (P< 0.05) difference among all the treatments in terms of weight gain, feed efficiency (FCR), oocyst count and reduction in mortality. The results of other anti-coccidials were not satisfactory, while both the vaccinated groups i.e. group G and H performed well in terms of oocyst count and decrease in mortality but their weight gain and feed efficiency were not good.
The results of this study will help to the feed millers in choosing the best feed additive anti-coccidial, while the farmers will get choice amongst anti-coccidial drugs or vaccines.

Publisher: 2001Dissertation note: The present study was designed to estimate the efficacy of two types of monovalent . tenella vaccines i.e. Formalin treated . tenella oocysts for 48 (FEV-48) and/or 96 (FEV-96) hours and irradiated . tenella vaccine. For estimation of the efficacy of the said vaccines, OPG counts weight gain, FCR and mortality records were compared amongst the control and test groups.
A total of 105 day-old broilers were equally divided into 5 different groups namely; A, B, C, D and E on day 3, each group comprising of 21 chicks. NDV vaccine was administered on day land 21 of age of chicks of all the groups. Group A acted as non-infected control, B as infected control, C was vaccinated with FEV-48, D was vaccinated with FEV-96 and E was vaccinated with 1EV on day 3 and 10 of age. Spread of contaminated faeces over the bedding with . tenella oocysts was commenced on day 12 upto day 17 of age of chicks. The OPG counts were conducted on each 4th day from day 18th to 52.
The results indicated that the first observation of OPG counts (day-18) showed heavy infection in all the control (infected) and test groups. In group B, 222200 oocysts were observed on day 18 which gradually reduced to 5300 on day 50 followed by zero on day 52. Group C (FEV-48) showed 131400 OPG counts, which sharply declined on each observation and showed 100 OPG on day 38 followed by '0' afterwards and showing significant differences from the control (P < 0.05). Group D showed gradual decline like infected control upto day 34, but ironically on days 38 and 42, 196.3% and 376.4% increase was noted, respectively as compared to group B, which again declined by day 50 with significant difference. In group E the first observation showed 119460. OPG counts which abruptly declined to 75 on day 38 followed by '0' on day 42. Groups C and E showed comparable results.
Weight gains were almost equal in all the test and control groups by day 14. The difference appeared on third observation between infected control and other groups. At the end of the experiment members of groups A, C, D and E gained 31%, 14%, 11.83% and 10.92% greater weights than group B. The FCR in ranked order was shown as A, C, E, D and B, showing the efficacy of FEV-48. Mortalities occurred in groups B, C, D and E as 4 (19%), 2 (9.5%), 1 (4.76%) and 3 (14.28%), respectively.

Publisher: 2002Dissertation note: Ticks infestation and piroplasmosis are serious problems of domestic cattle. The present study was conducted to find out the prevalent species of ticks and the piroplasms transmitted by these ticks. The effect of ticks and blood parasites on various blood parameters was also studied. The parameters included: RBC count, WBC count, Haemoglobin (Hb) estimation, erythrocytic sedimentation rate (ESR) and differential leukocytic count (DLC). The study was conducted from June to August, 2001.
A total of 80 cattle (40 local nondiscript cattle and 40 crossbred) were selected. Each type was divided into four groups i.e. A, B, C and D. The cattle of group-A were free from any infestation/infection. The animals of group B were only tick infested. Animals of group-C were only piroplasm infected and the animals of group-D were infested with ticks and the piroplasms. Each group from both the breeds consisted of 10 animals.
Haemotological examination revealed a significant decrease (P<0.05) in TEC, Hb and TLC in groups B, C and D as compared to group-A relating to each breed.
The lymphocytes were decreased from normal in all test groups in both the breeds, significantly. However, neutrophil and eosinophils were increased significantly in test groups as compared to control group (A). The values of erythrocytic sedimentation rate (ESR) showed a significant increase in groups B, C and D of both types of cattle as compared to the control group (A).
The overall results showed that the effect of mixed infection on haematology was greater than the single infection of ticks or piroplasm.
