Publisher: 2011Dissertation note: The pet dog is a domesticated animal, belonging to the family Canidae and it comes within the order Carnivora. The given nomenclature is used for all varieties of pet dogs. Earlier, this pet animal was used for different purposes which include hunting, fighting and also different types of work had been taken from it. Dermatophytosis is the common skin infection in dogs especially in the young ones. A total of 300 samples were collected. The 36 samples were found positive and then divided into 3 groups. In group K, Ketoconazole was applied topically twice a week. Later on the efficacy of Ketoconazole was observed by collecting the samples on day 7, 14 and 21 after the commencement of treatment, which was 20%, 60% and 90% respectively. Similarly, Group L was treated with Lime sulphur and the efficacy of Limesulphur against M.canis infection, was found to be 60%, 80% and 100% on day 7, 14 and 21 respectively. Group M was treated with Miconazole. The efficacy of miconazole against M.canis was found to be 50%, 75% and 100% on day 7, 14 and 21 respectively. At the end, it was concluded that Lime sulphur was the best drug of choice among the three drugs used and the efficacy of ketoconazole was lesser than the others.

Publisher: 2011Dissertation note: Study was carried out in district Rajanpur from February, 2011 to April, 2011 to find out percentage of infestation and to study chemotherapeutic trails against warble fly infestation in cattle in three tehsils namely Rojhan, Rajanpur and Jampur of district Rajanpur. In each tehsil 200 cattle were examined to record clinical signs of hypodermosis. For treatment of affected animals drug trail were done with Trichlorophon (Tagafon Star,Pakistan) and Ivermectin (Imec, SJG, Pakistan) 1% subcutaneously @ 0.2mg/kg body weight. Study included percentage of infestation in cattle in the households, veterinary hospitals and private farms. Average percentage of warbles in cattle was calculated and found 10 %, 17% and 16.5% in Rojhan, Rajanpur and Jampur respectively. It was found that percentage of infestation was 12% to 18% in hilly areas as compared to semi-hilly areas with 8% to16% and riverine areas 8% to 18% warble fly infestation in cattle. It was observed that warble fly infestation in cattle was absent in some plane areas in tehsil Jampur.
The comparison of different chemotherapeutic trails against Hypodermosis in cattle were observed and recorded. Three groups of cattle were made for chemotherapeutic trails against hypodermosis. Application of Tagafon in two different groups of cattle was carried out to evaluate their efficacy against Hypodemosis. In one group Trichlorophon (Tagafon Star,Pakistan) was applied with cotton gauzes by swabbing and spraying method with 5% solution of trichlorophon. In second group Trichlorophon (Tagafon Star, Pakistan) was given by drenching method with 2% solution at a dose rate of 0.2ml/kg body weight. In third group (Inj.Imec, SJG, Pakistan) Ivermectin 1% at dose rate of 0.2mg/kg body weight subcutaneous injection was carried out. Ivermectin1% was found to be 100% effective. Tagafon (Trichlorophon) was found 90% effective by swabbing and spraying method with 5% solution and Tagafon (Trichlorophon) by drenching method with 2% solution was found 85%effective against warble fly infestation in cattle in the study area. The data was analyzed statistically and found significant.

Publisher: 2012Dissertation note: It has been a long time since the affection of cats is with human beings. Cats have recorded as most adoptable pet of the modern world. Cats can be found anywhere in the world. Many diseases of cats are zoonotically important and they may cause zoonotic problem in human and mainly these pathogen are involved in enteric problems. The relationship of feline with human does provide many benefits to them but also act as a cause of zoonotic diseases.
A total of 300 fecal samples were collected from cats and were examined in the Clinical Medicine Laboratory, University of Veterinary and Animal Sciences, Lahore. The positive samples for Ancylostoma were 65 out of 300, indicating prevalence of Ancylostomiasis was 21.66%. For the chemotherapeutical trails 18 positive cats and 6 healthy cats were divided into four groups viz. A, B, C and D with 6 animals in each group. The cats of group A were treated with Pyrantel Pamoate @ 20mg/kg orally. The cats of Group B were treated with the Albendazole @ 50mg/kg orally. The cats of Group C were kept as positive control while the cats of Group D were kept as negative control.
The fecal samples were collected on day 0 pre-treatment and then on day 7th, 14th and 21st of post-treatment. The efficacy of the drugs was calculated on the basis of reduction of the eggs count from the fecal samples on the respective days. The efficacy of Pyrantel Pamoate on these days was 43.47%, 67.39% and 94.20% respectively, against Ancylostoma. The efficacy of Albendazole on these days was 30.77%, 60.44% and 86.81% respectively, against Ancylostoma. Thus it was recorded
that Pyrantel Pamoate was more effective against Ancylostoma than Albendazole as it caused more reduction of the egg count than albendazole.
Hematological study showed that the values of hemoglobin, packed cell volume and total erythrocyte count were lower in groups A, B and C as compared to non-infected control group. The values of total leukocyte count were higher in group A, B and C as compared to non-infected group. As a result of treatment in group A and B, the values of hemoglobin, packed cell volume and total erythrocyte gradually increased while that of total leukocyte count gradually decrease on day 7th, 14th and 21st post-medication. It has been observed during the present study that Pyrantel Pamoate and Albendazole showed their positive effect on blood parameters as a result of Ancylostomiasis with more efficacy of Pyrantel pamoate as compared to that of Albendazole.

Publisher: 2012Dissertation note: The parasitic load on deer affects them badly and eventually leads to death. In the present study a total of 100 feacal samples were collected from deer and were examined in the Clinical Medicine Laboratory, department of CMS, University of Veterinary and Animal Sciences, Lahore. Out of 100 samples thirty eight were positive and among these thirty eight, 12 deer were infected with cestodes, 6 with nematodes, 12 with trematodes, and 8 with the mixed infection of parasites. So, the prevalence of the cestodes, trematodes, nematode and mixed infection was 12%, 12%, 6% and 8% respectively. For the chemotherapeutic trails thirty positive animals and 10 healthy animals were divided into four groups A, B, C and D with 10 animals in each. The animals of group A was treated with albendazole @ 7.5mg/kg orally. Those of group B was treated with the ivermectin @ 1mg/ 50kg orally. The group C animals were kept as positive control and group D were kept as negative control.
The feacal samples were collected on the 0 day (pre-treatment), 7th, 14th and 21st day (post-treatment). The efficacy of the drugs were calculated on the basis of reduction of the eggs count from the feacal samples on the respective days. The efficacy of albendazole 42.59 %, 71.3% and 87.96% against cestodes, 33.33%, 60.3% and 82.88% against nematodes and 40.18%, 68.22% and 89.72% against trematodes at day 7, 14 and 21 respectively.. The efficacies of ivermectin were 42.59 %, 73.15% and 88.88% against cestodes, 51.78%, 76% and 91.07% against nematode while 42.85%, 64.28% and 85.71% against trematodes at day 7, 14 and 21 respectively.
It is thus concluded that the ivermectin is more effective drug than albendazole as it caused more reduction of the egg count than albendazole.

Publisher: 2012Dissertation note: Theileriosis is an infectious malady of equidae characterized by intermittent fever, loss of appetite, anemia, loss of weight, dyspnea, pale mucous membranes, jaundice and recumbency. Considering the significance and utilization of equines in our country and the substantial losses rendered by theileriosis, the present study was designed to study prevalence and chemotherapy of theileriosis in equines in and around Lahore.
For this purpose 300 equines (Horses=100; mules=100; donkeys=100) were examined for theileria infection.The blood was collected by ear tip puncture and from Jugular venipuncture. Then thin blood smear slide was prepared and dried up in air and stained with Geimsa's staining method and examined under microscope. Theileriaequiwere identified by their morphological characteristics as described by Rashid et al. (2009) and Guimaraeset al. (1997).Over all prevalence of Theileriaequiin equines was estimated as 58%. There was also a mixed infection of Theileriaequi and Babesiacaballiin some cases. Individually there was 54%, 64% and 56% prevalence of Theileriaequi found in horses, mules and donkeys respectively.
The effect of theileriosis on various blood parameters (Hb, ESR, TEC, TLC, DLC and PCV) was determined in 30 equines (Horses= 10; mules= 10; donkeys= 10). The remarkable decrease in hemoglobin, TEC, PCV and lymphocytes was observed. The value of ESR increased while there were no remarkable changes in TLC, monocytes, basophils, neutrophils and eosinophil.
For chemotherapy, 36 equines (Horses=12; mules=12; donkeys=12) positive for theileriosiswere divided into three groups (A, B, and C). Each group was further subdivided into three subgroups comprising of 4 animals in each subgroup. The animals of group A (Horses=4; mules=4; donkeys=4) were treated with Imidocarbdipropionate (Imizol®, ICI, Pakistan) @ 2 mg/kg BW I/M, and the efficacy of drug was found 91.7% in equines against theileriosis.The group B (Horses=4; mules=4; donkeys=4) was treated with Buparvaquone (Butalex®, ICI, Pakistan) @ 2 mg/kg BW I/M alone and was observed 66.7% effective. While the group C (Horses=4; mules=4; donkeys=4) was treated with Auk(Calotropisprocera)@ 0.3mg/kg BW, 8 doses at alternate days (local treatment), which was found 58.3% effective. The efficacy of drugs was measured on the basis of disappearance of clinical signs and blood smear examination at day 2, 4, 6 and 10 of post-medication. The efficacy of each drug was measured through recovery rate of the animals.
Finally, the data on prevalence of theileriosis was estimated by Pearson's chi-square test for significance whereas data on hematology was analyzed by Student's T-test using statistical software package STATA 9.1 (College Station T×77845, USA), P < 0.05 was considered significant.
Considering the significance and utilization of equine in our country and the substantial losses rendered by theileriosis, the present project was designed to check prevalence and chemotherapy of theileriosis in equines in and around Lahore. The results of this study will help farmers and veterinary practitioners in field.

Publisher: 2015Dissertation note: Foal diarrhea is one of the major threats to equine industry that causes high morbidity and mortality. Electrolytes (Na, K, Ca, Fe, Cu and Li etc) and water losses reduced dietary intake and probable translocation between intracellular and extra cellular compartments. Electrolytes are essential for controlling membrane potential, muscle contraction, nerve condition, and enzyme reactions, and they play a central role in the physiological processes. Serum electrolytes and trace elements deficits are the major causes of fluid and acid-base imbalance in diarrheic foals. Keeping in view the importance of foal diarrhea and its impact on the equine industry the current study was designed to determine serum concentration of electrolytes (Ca, K, Na) and trace elements (Li, Cu, Fe) along with the associated risk factors in diarrheic foals.
The present study was designed to examine diarrhea in foals at various equine stud farms, private and public veterinary hospitals. For this purpose a total of (n=100 foals) suffering from clinical diarrhea irrespective of the cause of diarrhea selected randomly after clinical examination and (n=10 foals) negative for diarrhea as control were included. Data of each diarrheic foal was collected separately in a data capture form. Blood and serum sample were collected for hematological and serum biochemical studies, respectively. Concentrations of serum electrolytes (Ca, Na, and K) were analyzed by Flame Photometry and trace elements (Cu, Li, and Fe) were estimated through Atomic Absorption spectrophotometer. PCV was determined by micro hematocrit method. Risk factors including species and age were analyzed for association.
Foals which were suffered from diarrhea showed increase in Pack cell volume. Serum concentration of Sodium, potassium, calcium, iron, copper and lithium were measured in diarrheic foals by atomic absorption and flame photometer method and were compared with healthy group of foals.Foals having diarrhea showed an acid baseimbalance as a result decrease in serum electrolytes and trace elements. The blood acid-base balance is precisely controlled because even a minor deviation from the normal range can severely affect many organs. The body uses different mechanisms to control the blood's acid-base balance.Sodium and potassium and calcium are important electrolytes imbalance in diarrhea. Potassium level was increased in foals having diarrhea. Calcium concentration in ppm significantly decreased from its normal value. In some diarrheic foals increased in level of calcium was also observed because these foals have blood in their feces that result in the calcium to come in blood as a clotting factor. Trace elements such as Cu, Fe and Li are needed in a very little concentration for many physiological functions. The serum iron was measured in foals having diarrhea.The iron concentration was less than normal value.The deficiency of iron lead to anemia. Clinical signs of anemia because of irondeficiency are rarely seen in foals. Therefore, mineral imbalances influence iron metabolism and may cause iron deficiency in foals. The serum copper concentration was significantly decreased in the diarrheic foals. Copper concentration is also related to the packed cell volume as in anemia copper deficiency is a significant feature. Copper is important element and its deficiency lead to decrease in serum concentration of iron. This decreased level might be because most of the circulating copper in plasma is attached to the serum glycoprotein, ceruloplasmin. Ceruloplasmin has ferroxidase activity and may be required to deliver iron into the circulation Therefore it was observed that low iron concentrations might have resulted from copper deficiency.The concentration of Lithium was also decreased in diarrheic foals when compared to healthy foals.

Effects Of Aflatoxin M1 (Afm1) On Sheep And Efficacy Of Mycotoxin Binders
by Muhammad Akhtar (2008-VA-122) | Dr. Jawaria Ali Khan | Dr. Muhammad Hassan Saleem | Dr. Muhammad Ovais Omer.
Material type: ; Literary form:

Publisher: 2015Dissertation note: Livestock production is an important part of national economy and it plays a significant role in providing the high quality food for human beings. Dairy industry of Pakistan contributes up to 46.8% in the agriculture and about 10.8% of the GDP in the form of milk, milk products, meat, hides, skin and bone meal (Ghaffar et al. 2007). Molds are fungi consisting of filaments that are present in the feed of animals. Molds can cause many infections in dairy cattle, especially during period of stress when their immune system is depressed. They cause a special disorder that is termed as Mycosis. Specific mycotoxins are produced by these fungi and when these animals eat such type of feed then they also engulf such dangerous mycotoxins. Mycotoxins are produced by a wide range of various molds and can be classified as secondary metabolites meaning that their function is not essential to the mold’s existence (Whitlow and Hagler 2005).
In the European countries, sheep milk is mainly produced in the Spain, and it is about 403000 tons per year. The main purpose of this milk is to produce cheese. Manchego cheese is considered as the best quality cheese in the world. This is the only technique by which we can produce the high quality of cheese (Rubio et al. 2009). These Aflatoxins are the fungal main dangerous constituents that can contaminate the feed of animals very easily. If AFB1 contaminated ration is consumed by animals then metabolism takes place in these toxins and excrete AFM1 in milk which further reduces milk production. More long-lasting aflatoxin poisoning produces very dissimilar signs that may not be clinically superficial and decreased rate of production in young animals. Severe aflatoxicosis causes hepatitis, hemorrhage, and death. Decreased growth rate is the most delicate clinical symbol of chronic aflatoxicosis, and it may be the only readily obvious abnormality. Natural toxins considerably show the greater danger to human and animal health. One large group of natural toxins that are universally
Introduction

documented as poisons of food and feed are the mycotoxins. The toxins occur naturally in various animal feeds, including corn and cottonseed. To control AFM1 in milk, it is essential to decrease the feed contamination by AFB1 (Prandini et al. 2009).
The livestock is playing major role in enhancing agricultural productivity and it has also major contribution to decrease the rate of poverty in the rural areas of Pakistan. Most farmers have domesticated sheep in their home which are their major sources of income (Mahmood et al. 2009). Aflatoxins adulterated rations prompted important reduction in daily feed consumption and the means of body weight, body weight increment and feed transformation rates were radically affected during the exposure stage to aflatoxins. Furthermore, serum ingredients and ruminal measurements showed lessened liver function and digestive turbulences in sheep fed aflatoxin (Jouany and Diaz 2005)
Aflatoxins are included in that group of toxins which are considered as highly toxic toxins. Aspergillus parasiticus, Aspergillus flavus and Aspergillus nomius are those types of fungi which can produce very strong type of toxins. Aflatoxin B1 (AFB1) is considered as the most dangerous type of aflatoxin and it is very strong hepato-toxin (damaging the liver as a whole). It can also cause cancer, can produce teratogens, and may also cause mutation in the both animals and in human beings.
AFB1 being very toxic, can be activated by the special metabolism of liver and through cytochrome P450. The cancer causing ability of AFBI is ten times more than the AFM1. The conversion of AFB1 to AFM1 in the milk producing animals is in the range of half percent to about six percent. In milk producing animals the level of aflatoxin M1 is greatly altered by the contamination rate of aflatoxin B1 (Bognanno et al. 2006).
It is observed that the excretion pattern of aflatoxin M1 in the milk of sheep is lower than the excretion pattern of aflatoxin M1 in the milk of cows. Due to presence of aflatoxin B1 in the feed of animals and hence appearance of aflatoxin M1 in the milk of animals shows that
Introduction

milk of such animals becomes more toxic and more un-hygienic. The young ones having milk as their main feed ingredient may have much more chances of getting various infections. (Var and Kabak 2009). To check the level of aflatoxin M1 in the milk of sheep, various experimental studies have been performed in the whole world (Battacone et al. 2005). In Pakistan, there are many favorable environmental conditions in which various types of fungi can easily prompted (Iqbal et al. 2011). The contamination level of aflatoxin M1 in the milk of dairy animals and in the dairy products has been found by (Hussain et al. 2008).
Aflatoxins can be produced from fungal metabolites. Aflatoxin M1 is produced as the complete metabolism of aflatoxin B1 has taken place. Aflatoxin B1, when converted into aflatoxin M1 is appeared in the milk of that animals and the same aflatoxin M1 can also be appeared in the dairy products which can contaminate the feed of human too. Transformation of aflatoxin B1 into the aflatoxin M1 is around one to two percent. This transformation is highly dependent upon the feed of animals, transformation from one affected animal to other healthy animal, transformation from the milking of affected animal to the milking of healthy animal and from one day to another day also. It is also noted that as the level of aflatoxin B1 in the feed of animal is decreased down then the level of M1 in the milk of animals is also dropped down significantly but it takes about 72 hours for this dropped down (Nilchian and Rahimi 2012).
AFM1 had a resistant to thermal inactivation used during food processing procedure such as pasteurization and autoclaving. Storage of various dairy products was not effective in the reduction of this toxin (Ozdemir 2007). Aflatoxin M1 level in the milk of animals can also be found in 12 to 24 hours after the ingestion of aflatoxin B1. After this, its level can be raised within the few days. The estimation of conversion rate of aflatoxin B1 in the contaminated feed of animals into aflatoxin M1 in the milk that animal is elaborated as 1 to 3 percent in a specific range (Ozdemir 2007).
Introduction

Aflatoxin B 1 being very much dangerous mycotoxin, it is very much important to know about such methods by which the level of aflatoxin B1 in the feed of animals can be controlled. For this purpose we should first come to know the basic source of feed contamination of animals, and after this we should adapt such easy method to determine the level of aflatoxin B1 in the animal’s feed and such methods should be very cost effective. The best accepted and recognized method to determine aflatoxin M1 level in the milk of infected animals is HPLC high-performance liquid chromatography and TLC thin-layer chromatography (Thirumala-Devi et al. 2002). Aflatoxin M1 can be found in the milk of infected animals and can also be found in the products that are prepared from that contaminated milk. This contamination is the main problem arising now a days in the whole world (Fallah et al. 2009). Availability: Items available for loan: UVAS Library [Call number: 2237-T] (1).
