Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1991Dissertation note: The study was designed to find out the prevalence and intensity of treinatodes infestation in Buffaloes in Distt. Gujrat. For this purpose twenty villages out of 1516 were randomly selected. The study period was from January to May, 1991. The data were based on: 1. Informations obtained from nine Veterinary Hospitals regarding trematodal treated buffaloes. 2. Information obtained from buffaloes owners by interogations regarding trematodes infestations in buffaloes in the selected area. 3. Findings of five hundred buffaloes faecal samples from twenty villages. 4. In order to record the actual trematodal infestations, two hundred stomach and livers alongwith their bile-ducts were inspected in three abattoirs in District Gujrat. Data collected from Veterinary Hospitals indicated that 1252 (19.39%) out of 6554 buffaloes were positive for treinatode infection. Informations collected from owners of the buffaloes of twenty villages showed that 133 (17.52%) out of 746 young buffaloes and 689 (21.92%) out of 3143 adult buffaloes were effected with trematodes. Five hundred faecal samples were tested by fresh smear and sedimentation method from twenty villages and found that 144 (28.8%) buffaloes were suffering from trematodes in District Gujrat. In order to determine the intensity of fluke disease in the infected animals, quantitative faecal examination was done and it ranged from 30 - 87.6 epg indicating that the disease is likely to be pathogenic. Overall incidence of trematodes recorded in slaughtered buffaloes was 76.5%. It was concluded from the findings of the study that treinatodal infestation in buffaloes in District Gujrat are quite prevalent necessitating to adopt appropriate measures to control these infestations.

5. Imunization Of Rabbits Against Boophilus Microplus Using Midgut And Salivary Glands

by Mohammad Asif | Dr. Khalid Saeed | Dr. H. A. Hashmi | Dr. Khushi | Faculty of Veterinary Sciences.

Material type: book Book; Format: print Publisher: 2002Dissertation note: The current research was conducted as a simulation model in rabbits for the development of vaccines against cattle ticks Boophilus micro/us using tick salivary glands & midgut as the sources of antigens. The comparative efficacy of these vaccines was evaluated on the basis of antibody titres and tick rejection on the host in terms of mortality, decrease in egg laying and decrease in hatchability of eggs. It was found that the vaccine prepared from the midgut of B. microplus gave better results than the vaccine prepared from salivary glands. The highest percentage of dead ticks was observed in animals which were given midgut vaccine (21.82%). This vaccine also caused a significant decrease in the egg laying capacity of the ticks (35.83%). However, none of the vaccines had any significant effect on the hatchability of eggs laid by the ticks. The highest antibody titers were observed in rabbits injected with midgut vaccine (GMT=5.50), which was 45.28% higher than rabbits given salivary gland vaccine. The overall success rate for midgut vaccine, in terms of tick mortality on host, decrease in egg laying capacity and antibody titer,. was 37.06% for midgut vaccine while only 16.51% for salivary gland vaccine. The results are very encouraging and it is hoped that with the original host i.e. cattle, more satisfactory results can be achieved.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2012Dissertation note: Goat rearing is a traditional activity in peri-urban areas and villages and plays an important role in the nutrition, social and economic needs of the population. Gastrointestinal nematodes are common in various production systems and these infections are the single most significant constraint to small ruminant productivity. The present study was carried out at Saidu Sharif, District Swat to generate data about the gastrointestinal (GIT) nematodes prevalent in the area. To record the prevalence of various nematodes of goats, a total of 150 faecal samples were examined. A total of 61/150 (40.67 %) of samples were found positive. Different species were identified and included Nematodirus spathiger (28.66 %), Haemonchus contortus (14.66 %), Trichostrongylus spp (4 %), Strongyloides papillosus (6 %) and Trichuris ovis (11.33 %). Highest prevalence of GIT nematodes were found in young and immature animals (48 %) with mean EPG 282 and 211 respectively. Adult had lower infection rate (26 %) with mean EPG of 142. Sex related prevalence indicated that male had higher prevalence (46.66 %) than female (34.66 %) and greater intensity of infection in males as compare to females. Higher infection rate with GIT nematodes was recorded in pregnant goat (42 %) as compared to non pregnant (33.92 %). House hold animals showed high infection rate i.e. 45.33 % with mean EPG of 254 as compared to commercially raised animals which had infection rate 36 % with mean EPG of 169. The Study -------------------------------------------------------------------------------------------------- SUMMARY 71 showed significant difference of egg per gram count between breeds. Beetal goats had high infection rate (100 %) and intensity as compared with other breeds. Higher egg shedding was recorded in animals around parturition as compared to dry goats.

by Amjad Atta Bhatti | Dr. Khalid Saeed | Dr | Prof. Dr. Kamran Ashraf.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2012Dissertation note: Trichomonas foetus (T. foetus) is a protozoan parasite of reproductive tract of large ruminants and causes abortion. This organism is found in males and females associated with varied pathology and clinical symptom. Disease has venereal transmission and male remain infected throughout the life. Pakistan is a developing country and artificial insemination facility is not available to all farmers and some are reluctant to avail it. This study was designed to check the prevalence of T. foetus in large animals in district Hafizabad. One hundred and fifty preputial and vaginal samples were collected from cattle and buffaloes 75 each. These samples were from 100 females and 50 males. Vaginal mucus from females was thoroughly examined for T. foetus in direct smear and in smear stained by Giemsa stain. Male samples were subjected to examination by direct smear, centrifugation and stained smear performed from sediments for detection of T. foetus. Overall prevalence of T. foetus was 12.0% (18/150) in sampled animals and species wise T. foetus infection was 8% (6/75) for cattle and 16% (12/75) for buffalos. Sex related prevalence of T. foetus in cows is 6% (3/50) and in buffaloes was 14% (7/50). Infection was more common in buffalo bulls 20% (5/25) as compared with cow bulls 12% (3/25). There was no difference in diagnosis of T. foetus in females by direct smear or by examination of stained smears. Whereas stained smears prepared from sediments of preputial washings were more sensitive in diagnosing of T. foetus infection as compared with direct smear method. Study also indicated that infection was exclusively seen in animals that were involved in natural breeding. Availability: Items available for loan: UVAS Library [Call number: 1438,T] (1).

by Sara Mehmood | Dr. Muhammad Lateef | Dr. Aftab | Dr. Khalid Saeed.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2012Dissertation note: Mosquitoes are major vectors, in transmitting many diseases like malaria, filariasis, Japanese encephalitis and dengue fever etc, which are greatly, affecting human beings worldwide. Malaria is a major global health problem. There are estimated 247 million malaria cases with almost half of the global population at risk and nearly a million deaths each year. Several Anopheles species are responsible for transmission of malaria .i.e. Anopheles stephensi, An. Subpictus. Control of mosquitoes primarily depends on chemical insecticides includes organochlorine, organophosphates, synthetic pyrethroids, IGRs etc, but all these chemicals have developed a feedback of environment ill-effect, have negative impact on non-targeted biota and most mosquitoes species have become physiologically resistant to these insecticides. These problems have highlighted the need for the development of new strategies for mosquito control. Botanical insecticides are naturally occurring products that are derived from plants. The use of plant extracts for insect control has several appealing features, as these are generally more biodegradable, less hazardous, and rich storehouse of chemicals of diverse biological activity. The current study were carried out to evaluate the activity of methanol extract of leaves of C.fistula, and ripened fruits of P. nigrum against Anopheles mosquito. Among both of these plants the methanolic extracts of Piper nigrum (black pepper) were exhibited remarkable adulticidal and larvicidal potentials. The percentage mortalities were increased by gradual increase in extracts concentrations. Larvae were more susceptible to these methanolic pepper extracts than adults. Larvae were showed mortalities even at very low concentrations. The LC50 values obtained by using probit analysis were 25.05 ppm and 12.05 ppm after 24 hrs and 48 hrs respectively, whereas LC90 were 78.63 ppm and 53.06 ppm respectively for aulticidal bioassays. Larvicidal assays were also showed good results having LC50 values as 3.87 ppm and 2.07 ppm after 24 hrs and 48 hrs respectively, whereas LC90 were 10.63 ppm and 6.56 ppm respectively. Cassia fistula (golden shower) leaf extracts were also showed promising mosquitocidal efficacy against Anopheles stephensi. LC50 values obtained by using probit analysis were 35.13 ppm and 16.18 ppm after 24 hrs and 48 hrs respectively, whereas LC90 were 94.57 ppm and 76.43 ppm respectively for aulticidal bioassays. Larvicidal assays were also showed good results having LC50 values as 44.99 ppm and 24.40 ppm after 24 hrs and 48 hrs respectively, whereas LC90 were 106.12 ppm and 76.30 ppm respectively. It is concluded that methanolic extracts of these plants Cassia fistula and Piper nigrum have high potential of adulticidal & larvicidal activities. So the extracts of these plants can be used as an alternatives to the conventional insecticides for long lasting mosquito problems as these are less hazardous and ecologically feasible. However, a lot of work on biochemistry as well as insectidal activity and on other aspects has to be done. Availability: Items available for loan: UVAS Library [Call number: 1474,T] (1).

11. Characterization Of Recombinant Surface Antigen-1 (Rsag-1) Of Toxoplasma Gondii Through Western Blotting Using Mouse Anti-Serum

by Mati Ullah Khan (2008-VA-107) | Dr. Haroon Akbar | Prof. Dr. Khalid Saeed | Dr. Uzma Farid Durrani.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Toxoplasmosis is caused by Toxoplasma gondii, which is an obligate intracellular apicomplexan protozoan parasite. The infection is highly prevalent worldwide, and is important both from veterinary and human health concern. In the past recombinant surface antigen-1(rSAG-1) has been shown to be a good candidate for the development of immuno-diagnostic kits as well as Vaccine. Through immuno-blotting, Surface antigen-1 has been identified by sera collected from Toxoplasma gondii infected cats, dogs and humans. Looking at the importance of this health threatening issue, the current study was designed to characterize rSAG-1 through western blotting for development of local diagnostic kit through western blotting using mouse anti-serum. The rSAG-1 was previously expressed under the project of Grand Challenges Canada at Molecular Parasitology laboratory, Department of Parasitology, University of Veterinary and Animal Sciences, Lahore. Recombinant SAG-1 was quantified by using commercial kit based on BCA assay. The 15 μg of rSAG-1 was inoculated subcutaneously (S/C) 3 times with each 2 weeks interval in mice to raise hyper-immune serum. Blood was collected from mice two weeks after the each injection through lateral Retro-Orbital Bleeding (Sharma et al. 2014). Serum was collected by centrifugation. The rSAG-1 was electrophoresed on 12% polyacrylamide gel through SDS-PAGE technique and the protein was transferred to nitrocellulose membrane for western blotting. Anti-serum raised against rSAG-1 was cross-reacted with the rSAG-1 already immobilized on the nitrocellulose membrane. Anti-mice immunoglobulin G conjugated with Alkaline Phosphatase (AP) was used as secondary antibodies for the development of immuno-blot. Immuno-blot revealed a band of 35 KDa.

12. Molecular Diagnosis Of Anaplasmosis In Buffaloes

by Muhammad Salman (2008-VA-135) | Prof. Dr. Khalid Saeed | Dr. Muhammad Imran Rashid | Dr. Wasim Shehzad.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Bovine Anaplasmosis is a tick-borne haemo-rickettsail disease, caused by Anaplasma species transmitted mechanically by flies, biologically by ticks and blood contaminant fomites. It is an economically important tick-borne disease of buffalo in tropical and sub-tropical areas of the world. In current study, we developed and optimized PCR first for detecting Anaplasma at genus level in buffaloes. One hundred (100) blood samples were collected from buffaloes around the Lahore region. The stained thin blood films were examined microscopically and 37% blood samples were found positive for intra-erythrocytic bodies which were then selected for DNA extraction. The DNA was extracted using commercially available kit for eventual use in optimization of PCR for diagnosis of bovine Anaplasmosis. The primers were designed targeting 16S rRNA gene of Anaplasma. For the detection, the PCR product was run in 2% agarose gel stained with ethidium bromide and thirty seven samples showed the amplification band at 179bp. The selected samples were sent for ABI sequencing to Singapore for the accurate detection of the Anaplasma species. The sequencing results were blasted with database of Genbank and we observed homology with Anaplasma phagocytophilum. We found 37% prevalence of Anaplasmosis in buffaloes through PCR. However more studies are required to confirm the species of Anaplasma infecting buffaloes (Bobalus bobalis) by designing species specific primers. Furthermore, additional studies are needed to establish the epidemiology of Anaplasmosis by using molecular tools in different geographical areas of the country for their better control.

13. Control Of Gastrointestinal Nematodes By Anthelmintics In Buffalo Heifers And Its Effect On Weight Gain

by Tanveer Saroia (2008-VA-062) | Prof. Dr. Khalid saeed | Dr. Nisar Ahmad | Dr. Ali Ahmad Sheikh.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: Parasitic problem is a major constraint of ruminant production and causes great economic losses to dairy industry by retarded growth, low productivity and increased susceptibility of animals to other infections. The parasitic infections cause productivity losses through reduced feed intake and decreased feed efficiency. Even subclinical or chronic infections are responsible for economic losses in large ruminants. Hypothesis of the study was that administration of anthelmintics will improve weight gain in infected buffalo heifers. One hundred faecal samples of buffalo heifers of age 1-2 years were screened and 58 were found positive for gastrointestinal nematodes. The species of nematodes found prevalent in these animals were Trichostrongylus, Oesophogostomum, Haemonchus, Toxocara, Trichuris and Ostertagia. Thirty buffalo heifers with high EPG were selected and divided into 3 equals groups A, B and C. In this study Group A was a positive control group. Group B was administered Ivermactin (Bomectin) pour on at the dose rate of 1ml / 20 kg body weight. Group C was administered Oxfendazole (Systamex) orally at the dose rate of 1ml/ 10 kg body weight. The effect of these anthelmintics on EPG and weight gain were recorded after every 15 days. This study period was of 90 days (3 months) duration. There was increases in the EPG of positive control group and percent increases was 7.10%, 10.65%, 18.10%, 30.17%, 33.72%, 46.15% at days 15, 30, 45, 60, 75and 90. The percentage decrease in EPG for the group B was 98.22%, 97.04%, 91.12%, 77.51%, 60.94%, 46.74% at days 15, 30, 45, 60, 75 and 90 post treatment and the percentage decrease in EPG for the Group C was 95.80%, 92.81%, 88.62%, 71.85%, 58.68%, 26.34% at days 15, 30, 45, 60, 75 and 90 post treatment. Both anthelmintics cause significant reduction in epg medicated animals as compared to non-medicated animals. There was no difference in the two anthelmintics. The average weight gain per day for Group A (Positive Control) is 0.17 kg per day, for Group B (Ivermectin) is 0.44 kg per day and for Group C (Oxfendazol) was 0.4 kg per day. This shows significant difference between treated groups with non-treated group but there was no difference between the treated groups. It is concluded that ivermectin and oxefendazol can be used for the control of gastrointestinal nematodes. It is recommended that animals may be moved to clean facility after treatment so they are not reinfected. Repeated treatment is suggested to maintain the EPG at low level. Suggestions of the present study are 1. Monitoring of animals for gastrointestinal nematodes by modified McMaster Egg Counting technique. 2. Regular deworming 3. Improved management Availability: Items available for loan: UVAS Library [Call number: 2405-T] (1).

14. Occurrence And Economic Losses From Theileriosis On Commercial Dairy Farm Of Holstein Friesian

by Muhammad Rashid (2014-VA-503) | Dr. Muhammad Imran Rashid | Prof. Dr. Khalid Saeed | Dr. Liaquat Ahmad.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Background: Theileriosis is a tick-borne disease and it is transmitted by the bite of ticks. Previous work on disease problems in the study area suggested that Ticks and Tick-Borne Diseases (TTBDs) are the major constraints to cattle production. They cause economic losses to farmers in terms of cattle mortality, loss of body weight, loss of milk production and costs of control of TTBDs by use of acaricides. Theileria is one of the major threat to cattle as it causes anemia, weight loss, decrease production, mortality, treatment cost and cost for the control of theileria. The proper data for losses atributed to theileriosis is still not available in Pakistan. For this purpose a study was carried out in a commercial exotic dairy farm to evaluate losses associated with theileriosis Methodology: The study was done during the period of theileriosis to calculate its economic effect on animal health and production. A total of 150 animals were selected randomly using random number sample formula. The animal tag numbers were compared with random number table, comparing animals were slecteded for study. Thin blood smear was performed for diagnosis haemoparasite, further PCR was performed on those animals that were found +ve for intraerythrocytic bodies. Faecal examination, California mastitis test, teat abnormality and parturition history were recorded for the screening of these factors that decrease milk production. After final grouping, milk production was recorded to identify the effect of theileriosis on production. As theileriosis cause anemia due to destruction of RBC’s. body condition scoring was also performed. Physical examination (lymph node and body temperature) of animals were also performed to evaluate the clinical and subclinical theileriosis. Results: For the evaluation of theileriosis, microscopy was performed on all the animals’ blood samples. Haemoparasites were found in 28.67%. These were further processed by PCR for the CHAPTER 6 SUMMARY Summary 55 detection of theileriosis. Theileria was found in 27.90%. Screening of clinical and subclinical mastitis by Califirnia Mastitis Test and microscopy for gastrointestinal parasite were performed. On faecal examination, there found nematode, cestode and balantidium in 51.72%, 60.92% and 42.53%% respectively. After deworming with Valbazine and curafluke, nematode, cestode (monzia), balantidium and coccidiosis were found in 0%, 39.13, 43.48% and 4.35% respectively. Before grouping clinical and subclinical mastitis were found in 5.38% and 24.62% respectively. After grouping clinical and subclinical mastitis were evaluated by California mastitis test with two weeks interval. At 7th week clinical and subclinical mastitis were 3.85% and 7.69% due to improved management. The decrease in milk production for clinical and subclinical theileriosis was 87 lit./animal and 42.77 lit./animal. Costs for control, treatment and mortality were 0.12%, 0.20% and 13.09% respectively from overall farm expenditure. The prevalence of haemoparasite was 28.67%, while the prevalence of theileriosis was 8%. The new cases of theileriosis were recorded and incidence of theileriosis was found to be 2.25%. Overall losses due to theileriosis was 13.70%. Outcomes: We can conclude from our finding that theileriosis has drastic affect on the profitability of the farms. Then losses can be attributed to decreased milk production and mortality. Medications and control measure for theileriosis have added effect on the losses at exotic animal breed dairy farms. Perspectives: Cost analysis studies need to be done on different dairy farms of cattle of different breeds at different ecological/climatic zones of Pakistan so that investors would know the risks of establishing dairy farms.

by Muhammad Saqib Ali (2008-VA-188) | Prof. Dr. Khalid Saeed | Dr. M. Imran Rashid | Dr. Muhammad Ijaz.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: Gastrointestinal nematodes are responsible for wide range of health problems, economic losses in bovines and are characterized by reduced milk production, decreased working efficiency and even death. This study was done to evaluate the effect of different anthelmintics on nematode control in different parity cattle at calving and their effect on milk yield. In this study, we screened cattle of 1st and 2nd parity for nematodes. Animals were randomly selected in each group. In first parity animals, we found 23 positive cattle which were divided into 3 different groups while in second parity animals, we found 20 positive cattle which were divided into 3 groups. We used Albendazole (Velbazine) @ 10mg/kg body weight and levamisole (Nilverm) @ 7.5mg/kg bodyweight for treatment. In this study both drugs were found effective in controlling nematodes infections in cattle. Percentage reduction of epg by albendazole was 48.20%, 85.34%, 93.90% and 51.54%, 81.43%, 91.74% on day 7, 14 and 21 in 1st and 2nd parity animals respectively. Percentage reduction of epg by levamisole was 44.45%, 76.92%, 88.03% and 46.60%, 73.78%, 85.43% on day 7, 14 and 21 in 1st and 2nd parity animals respectively. The increase in milk production in current study was 0.39 liter per day and 0.92 liter per day in 1st and 2nd parity cattle respectively. Albendazole increased the milk fat by 0.07 %, while levamisole decreased 0.02 % in 1st parity cattle. In 2nd parity cattle, there was sufficient increase of 0.1% of milk fat by albendazole while levamisole has decreased 0.05 %. We conclude from our studies that anthelmintic treatment of recently calved cattle have significant effect on milk production due to the nematode control. Milk production increased significantly in 2nd parity friesian crossed cattle following anthelmintic treatment as compared to Summary 70 1st parity animals. Levamisole has negative effect on fat concentration in friesian crossed cattle while albendazole treated cattle has positive effect. Albendazole has been found more efficient in reducing EPG of helminths in both parity animals as compared to levamisole treated animals. It is recommended that cattle should be checked for GIT parasites by faecal examination on regular basis so that cattle should be dewormed when needed.
