Histopathological changes were studied in Swiss albino mice (N:36)which were challenged with the South Indian local strain of Trypanosoma evansi. Each animal was infected with 5×105 trypanosomes intraperitoneally. The animals were examined daily for development of clinical signs and infection status by wet blood-films made from the tail veins. The infected mice were dull and depressed from two days post-infection (DPI) onwards. Systematic post-mortem examination of the infected mice was performed and pathological changes were recorded. The different tissue samples were collected in 10% formalin and were used to study the histopathological changes. Postmortem examination from 3-4 DPI (the maximum period of observation) revealed splenomegaly, hepatomegaly, marked congestion of lungs, presence of fl uid in peritoneal cavity. Histopathologically, heart muscles showed hyaline degenerative changes and haemorrhages. Liver parenchyma revealed congestion of central vein and sinusoids, binucleated hepatocytes and fatty change of hepatic cells. Thickening of interstitial space with mononuclear infiltration, areas of collapse, areas of emphysema, edema and dilated and congested blood vessels were the histopathological changes noticed in the lungs of the infected mice. In the spleen, giant cells aggregation, hyperplasia, thickening of capsule and trabecule were the changes indicating irreversible degeneration. The affected kidney showed inter-tubular hemorrhages in the cortex, medullary hemorrhages, congested glomerulus, atrophied glomerulus, desquamated tubular epithelium and disruption of renal tubules at some places.

Many parasitology laboratories practiced the McMaster technique as a method in obtaining the quantitative diagnosis of Strongyle eggs burden in farm animals especially ruminants. The McMaster technique also play a crucial role in faecal egg count reduction test (FECRT) for anthelmintic resistance identification. Some laboratoriesrecommend two-chamber counting method while some recommend single chamber counting method. This study focuses on the comparison between single and double counting in McMaster technique fordetection of Strongyle egg count. In this study, it is shown that there is no significant difference between both methods basedon the p-value obtained which is p>0.05 from 127 fresh goat faecal samples. The techniques practised during the study follow the standard established technique. Single chamber counting is suitable for a large number of faecal samples from big herds because it is faster, less laborious and produces sensitive and reliable results in Strongyle egg count. As more commercial farms are set up, there is a need to conduct a fast and efficient test to help farmers evaluate their livestock worm burden.

Diarrhoea in calves is considering a serious clinical problem inBangladesh. Calf is the back bone of the dairy industry. Diarrhoea in farm animals, especially in neonatal calves is one of the most challenging clinical syndromes encountered by large animal Veterinarypractitioners. The present investigation was conducted with the aimed to evaluate the efficacy of ciprofloxacin and gentamycin in the treatment of diarrhoea in neonatal calves. The studied was carried out for a period of six month from January 2013 to June 2013 in Kanaighat, Sylhet, Bangladesh. Calves (n=60) under 10 days of age with clinical signs of diarrhoea were randomly divided into two groups. One group was treated with intramuscular ciprofloxacin at a dose of 5 mg/kg once daily, while other group was treated withintramuscular (IM) gentamycin (dose of 5 mg/kg) once daily for three consecutive days. Calves evaluated clinically from the treatment and the recovery rates for the ciprofloxacin and gentamycin groups afterthree days of treatment were 73.33% and 66.67%, respectively. This trial revealed ciprofloxacine administered through IM route from the first day of the clinical sign observed was more efficacious in calfdiarrhoea compared to gentamycin.

Quail closed-house system is a house that support quails’ optimumrequirements as far as temperature, relative humidity, ventilation and light are concerned. One of the four units of quail closed-house systems at the Institute of Poultry Technology, Malacca was used in this study. The objective of this project was to evaluate the performance of the quail closed-house system by comparing the condition of the house under current management condition and after the Standard Operating Procedure determined by DVS was adhered. Thehouse performance was evaluated by observing its ability to achieve an optimum temperature range of 20°C to 27°C with a relative humidity between 60% to 80% as perfect surroundings for quails. At the end of the experiments, the results showed a decline in internal temperature at almost 3°C and increasing in a relative humidity of 10% after all the specifications and procedures were followed.

The aim of this study was to investigate the bacteria found in different parts of the genital system in cows and the susceptibility to different types of antibiotics. The genital systems of sixteen cows were collected from Al-Hilla, Iraq slaughterhouse. Isolation and identification of bacteria were made for each part of the genital system and antibiotic susceptibility tests was conducted to the isolated bacteria. The results of this study indicated that there were several types of bacteria present in the genital systems of cows. Different species of bacteria were isolated from the samples including, Escherichia coli (28.97)%, Klebsiella spp. (16.82)%, Salmonella spp. (14.95)%, Proteus spp. (13.08)%, Staphylococcus aureus (11.21)%, Staphylococcus epidermidis (8.41)% and Streptococcus spp. (6.54)%. In vitro susceptibility towards different types of antibiotic indicated high susceptibility of Escherichia coli to antibiotic group impenem and ciprofloxacin, while Klebsiella spp. was found to be most susceptible to ciprofloxacin and amikacin. Both Escherichia coli and Klebsiella spp. showed resistance to piperacillin and tetracycline. It was concluded that Escherichia coli was the most predominant bacteria in genital system of cows and were most susceptible to antibiotic impenem and ciprofloxacin.

The Department of Veterinary Services (DVS) established a subsidy programme to build low cost swiftlet houses, under the auspices ofthe eKasih programme. This programme is aimed at aiding entrepreneurs in the swiftlet industry to produce good qualitybird’s nests. In 2013, eleven swiftlet houses under eKasih Program in Johor, Perlis and Pahang were chosen randomly to be evaluated after a year of completion. The main factors affecting its functionality, such as temperature, relative humidity and light intensity inside the swiftlet houses were recorded and analysed. The results showed that most of the eKasih swiftlet houses built under this programme did not meet the recommended in house conditions due to several reasons. The houses built in this programme failed to attract the birds into the houses to build nests. Although there were some houses that produced bird’s nests, it was found to be substandard in terms of quality. Thus, this study revealed the importance of various factors needed for the successful establishment of swiftlet houses to produce good quality bird’s nests.

The characteristic thin skin of the scrotal sac in a rabbit was tornresulting in traumatic exposure of the right testicle. Bilateral orchiectomy through an open scrotal approach was performed undergeneral anaesthesia. The rabbit was premedicated with Acepromazine (0.5 mg/kg, 0.15 ml) and Flunixin meglumine (1 mg/kg, 0.03 ml,) intra-muscularly. Isoflurane was used for induction at 5% with O2flow rate at 0.7 L/min and maintenance Isoflurane, 1.5% - 3%, O2 flow rate = 0.7 L/min) of general anaesthesia. Both right and left testicles were removed and the hemiscrotal incision was closed with 4-0 Vicryl, horizontal mattress suture pattern. Post-operative treatments with antibiotic and anti-inflammatory agents wereinstituted and the client was advised about how to safely manage aggressive behaviour of rabbits towards each other. The surgicalsite healed without complication and the neutered rabbit recovered fully within 14 days.

Animal welfare is the state of the animal in its attempts to cope with its environment, and it can be measured and improved by the action of man. Recently, the topic “Animal Welfare” has become more important, resulting from the discovery that the management of animals in life has impact on the <em>post mortem</em> meat quality. This study aimed to determine the effect of transport batch number of pigs transported by batch, type of route and the time elapsed between the exploration and slaughter in the occurrence of lesions, considered as indicators of animal welfare at the slaughterhouse. At one slaughterhouse of pigs located in the northern of Portugal, 834 animals were monitored in order to check the occurrence of lesions consistent with lacerations, erythema, bruising and fractures, from a total of five different transport batches. The global analysis of the data showed that lacerations were present in 72% of animals and was the most common type of lesion, followed by erythema, bruises and broken bones presented in 20%, 11% and 1% respectively. The size of each batch, the duration of the journey and the time spent in the lairage significantly influenced the occurrence of observed lesions, particularly, lacerations, erythema and bruising. | Bem-Estar Animal consiste no estado do animal em sua tentativa de adaptação ao meio ambiente envolvente, podendo ser medido e melhorado com a ação do ser humano. Nos últimos anos o tema “Bem-Estar Animal” tem adquirido importância, resultante das grandes preocupações com o manejo dos animais em vida e constatação da influência que este tem na qualidade da carne <em>post mortem</em>. Este trabalho teve como objetivo determinar o efeito do lote de suínos transportados, respectivo tamanho, tipo de trajeto e do tempo decorrido entre a origem e o abate na ocorrência de lesões, consideradas indicadores mínimos de bem-estar animal em matadouro. Nos matadouros de suínos da região norte de Portugal, foram monitorados 834 animais com relação à ocorrência de lesões compatíveis com lacerações, eritemas cutâneos, hematomas e fraturas, em cinco diferentes lotes. Pela análise global dos dados, verificou-se que as lacerações estavam presentes em 72% dos animais e foi o tipo de lesão mais frequentemente observado. Seguiram-se os eritemas cutâneos em 20%, os hematomas em 11% e as fraturas em apenas 1% dos animais. O tamanho do lote de animais transportados, a duração da viagem e o tempo de permanência no matadouro influenciaram significativamente a ocorrência das lesões monitoradas, nomeadamente lacerações, eritemas e hematomas.
