Publisher: 1995Dissertation note: The project was designed to find out the efficacy of ivermectin and Coumaphos against ectoparasites in cattle and buffaloes. Thirty buffaloes infested for ectoparasites were selected for the treatment trials and divided into three groups i.e. Bi, B2 and B3 having ten animals in each group and thirty cattle infested for ectoparasites were selected for the treatment trials and also were divided into Cl, C2 and C3 groups.
The comparative acaricidal drug trials were conducted on 20 infested animals against ectoparasites of group BI and Cl having ten animal in each were medicated with Ivermectin (lvomec: MSD) injected once by s/c route at dose rate of 200 pg/kg body weight. Observation were made on 7th and 14th day post-medication. Skin scrapping examination was done. The overall efficacy of invermectin on 7th and 14th day in buffaloes was 40% and 80% and in cattle 50% and 90% respectively.
The comparative acaricidal drug trials were conducted on 20 infested animals for ectoparasites of B2 and C2 having ten animals in each were treated with Coumaphos (Asuntol: Bayer) at the dose rate of 30-50 gm/animal. On the 7th and 14th day post medication skin scraping examination was done. The efficacy of Coumaphos on 7th and 14th day in buffaloes was 50%, 50% and in cattle 70%, 70% respectively.
Animals were also observed for any side effect of both medicine. No side effects were observed during the period from treatment to last observation in any group i.e. groups BI, Cl and B2, C2 groups. On last observation no spontaneous recovery was noted. In B3 and C3 in untreated and control groups.
From the results of present study it is concluded that Ivermectin (Ivomec MSD) is the drug of choice for the treatment of ectoparasites in cattle and buffaloes when it is given at the dose rate of 0.2 mg/kg body weight by subcutaneous injection.

Publisher: 1995Dissertation note: One hundred and fifty day 01(1 broiler chicks were obtained from a local hatchery. They were reared upto day 26. All the birds were given feed having no coccicliostat.
At the age of 26 clays the birds were divided into five groups A, B, C, D and E. The D and B were control groups. The test groups were infected with 75000 sporulated oocysts On 26th day of age, group D was infected and non medicated while group E was kept non infected and non medicated. The group A, B and C were treated with clopidol, monensin and salinomycin respectively after the appearance of clinical symptoms.
The total oocyst counts in all groups on zero day of infection were nil and on 1st, 5th and 9th day of medication, groups A, B, C, D showed 25800, 20400, 23800, 197500 oocysts counts respectively, while group B examined nil being control non infected group.
The mortalities observed in groups A, B, C, D and E were 6, 2, 3, 8 and nil while percent mortality was 20%, 6.66%, 10%, 26.66% and 0.00%. In treated groups, monensin showed least mortality.
The feed intake and feed conversion of groups A, B and C were almost equal. While group D (infected and non medicated) was relatively poor. As far as group E (non infected and non medicated) is concerned it showed better results.
In haematological studies the average values of haemoglobin levels, erythrocytic count and total serum protein were lower post infection as compared to the respective control group E (non infected and non medicated). The total leukocytic count was increased in all groups as compared to group E (non infected and non medicated). The differential leukocytic count, the lymphocyte decreased, heterophils and monocytes increased. The eosinophils and basophils showed variation in their number.
The study showed efficacy of Monensin, Salinomycin and Clopidol in descending order respectively. Monensin was to be drug of choice against coccidiosis.

Publisher: 1997Dissertation note: Two hundred faecal samples, serum samples and paramphistomes used in the present study collected from main slaughter house of Lahore and from surrounding of the city.
Faecal examinations were carried out with fresh smear technique and 61.5% animals found positive for paramphistomiasis. Serum was separated from the blood samples collected from infected and suspected buffaloes for the performance of enzyme-linked immunosorbent assay. Paramphistome crude antigen was prepared from fresh stomach flukes, which contained 95.66 mg proteins/mi at 545 nm.
For performing the enzyme linked immunosorbent assay, the 96 well ELISA plates were coated with crude antigen & kept overnight & then the other procedure for the assay was followed, & the serum samples were tested with paramphistome crude antigen. In positive samples, the yellowish-brown colouration was formed.
In faecal examination, 61.5% and in the ELISA 100% of the animal found positive.
From the conclusion of the results if was found that ELISA (100%) has given more positive results then faecal examination (61.5%).
