Five years old seven month pregnant crossbred Jersey cow was presented with the history of anorexia and passing coffee coloured urine. Clinical examination of the animal revealed fever, pale mucous membrane, haemoglobinuria, suspended rumination and moderate tick infestation. Peripheral blood smear was stained with Giemsa stain and examined under compound light microscope found that the sample was positive for Babesia spp. The animal was treated with diminazine aceturate @ 3.5mg/kg b.wt IM along with supportive therapy. The animal was successfully recovered from the Babesiosis, after the ten days of recovery the cow was aborted.

An investigation was carried out to assess the nurtional , texture profile, microbial and sensory quality of wafer cones. Refined wheat flour and water, lecthin oil, vegetable fat, baking powder, SMBS (Sodium Meta Bisulphite) were used for the preparation of the wafer cone. Treatments were prepared with casein powder at the rate of 3, 5 and 7 per cent for enriching the wafer cones and control samples were prepared by using refined wheat flour. The quality assessment for moisture, protein and fat was carried out using infrared analyser from NDC technologies. Sensory acceptability was assessed by 9- Point Hedonic Scale and results were analysed statistically.

A Study on the comaprative efficancy of two types of serial collapasible fish traps differning   rear end funnel opening was carried out. With respect to Type-1 trap having rectangular rear end funnel opening and Type-2 trap with elliptical rear end were fabricated. The experiment was carried out in fishing ground one nautical mile off  the coast of mandatam (Lat 09 degree 16.633 'N  long .. 0.79 degree 08.992 ') Feb 2015 to june 2015. significant differnce wasobserved with respect to catch rate of different species caught irrespective of the design of traps (Plt;0.05). The difference in shape of rear funnel opening was found to be responsible for the significant difference in the catch rear funnel opening was about 3 times higher catch rate of Type-1 trap with rectangular rear funnel opening was about three times higher (17.1 Nos/ soaking day) than that of Type-2 trap with elliptical shaped rear funnel opening (5.9 Nos./ soaking day). The impact of seasonal variation on the catch rate was found to be insignificant (Pgt; 0.05). Though Psammoperca waigensis was found to be the dominant specices in both  types of traps in terms of number, Epinephalus coioides ranked first in term  of weight and price per kilogram in both Type-1 and Type-2 traps. Irrespective of the types of traps tested, the higher catch rate, including all the species caught, and was observed during the month of February which directly increased the overall catch rate during February month. With respect to the behavior of different species caught in relation to the types of traps tested, Sarcocendrum rubrum was recorded only in Type-1 trap which had rectangular shaped rear funnel opening and Muraena sp was recorded only in Type-2 trap with elliptical shaped rear end of the funnel opening which served like a burrow and hence facilitated the entry of eel. Type -1 trap gave three times higher gross returns than Type-2 trap.

A retrospective study was carried out to assess the udder affections of cows that were presented to the Large Animal Medicine Referral Clinic of Veterinary College and Research Institute, Thanjavur, Orathanadu, Tamil Nadu during June 2017 to April 2018. In this study involving 161 cows, 4 cows were found to have udder swelling / abscess diagnosed by ultrasound and percutaneous aspiration done under sonagraphic guidance. Udder ultrasound revealed hyperechoic alveolar tissue with anechoic/ heterogenous content in the affected quarters. Aspirated samples were culturally positive for the isolate Staphylococcus aureus and E. coli. In vitro antibiotic sensitivity test showed highest susceptibility to streptomycin followed by enrofloxacin and ciprofloxacin, gentamicin and amoxycillin with good recovery on treatment.

A Seven - month old female Kankrej calf was presented to Large Animal Clinics - Out-Patient - Medicine Unit of Madras Veterinary College Teaching Hospital, Chennai, with the history of recurrent tympany for two months with scanty dung with a pasty consistency. Onclinical examination of the animal, bilateral distension of the abdomen was noticed. Haematobiochemistry revealed neutrophilia with leucocytosis and significantly elevated Gamma-Glutamyl-Transferase values. In radiography, no change in the silhouette of reticulum could be appreciated other than a mild bronchial pattern. Ultrasonography revealed an anechoic encapsulated cavity with echogenic internal spots of the reticular wall. Based on these findings, the calf was diagnosed with an abscess in the reticulum. Accordingly, the abscess was drained and the animal was treated with antibiotics and supportive therapy and the animal recovered uneventfully.

Nasal washings and faecal samples were collected from 110 cows during the period between July 2019 and June 2020 in and around the Orathandu, Cauvery delta zone of Tamil Nadu to document the seasonal prevalence of Schistosoma nasale and Schistosoma spindale. These samples were processed and screened by using the standard parasitological techniques. Out of 110 nasal washings, 23 samples (20.9%) confirmed the Schistosoma nasale infection by the presence of eggs. No faecal samples could be detected positive for Schistosoma spindale infection during the study period

Administration of higher dosage of chlorine leads to a concern about proper dosage determination for shrimp hatchery operations. Hence, the dosage application needs to be reworked at the present context. Accordingly a Completely randomized design experiment with 6 treatments (control, 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm of active chlorine content) with 3 replications was conducted. The water quality and the bacterial load were monitored once in 3 hours continuously. The salient observations of the study was that the exposure time for residual chlorine to be nil for the tank with chlorination of 10 ppm concentration was 6 hours, for 20 ppm and 30 ppm it was 18 hours and for 40 ppm and 50 ppm it was 21 hours. Also the results shows that bacterial load was nil in all the treatments viz. 10 to 50 ppm. The pH of the water gets increased and then stabilized. It could be concluded from the study that the chlorination is required in shrimp hatcheries. But the optimum dosage is 10 ppm for ensuring better water quality in shrimp hatchery which is very much less when compared to the general dose of upto 30 ppm for other purposes. Another experimental trial with three replications was conducted to ascertain the survival of post larvae of P. monodon from PL5 to PL 20 with the 10 ppm active chlorine. The study showed that survival was high in 10 ppm.

Rabies is zoonotic viral encephalitis targeting the nervous system of several vertebrates and transmitted mostly through the saliva of the infected host causing extensive neurological dysfunction. In this study, 873 post-mortem examinations of different species of animals were done in the Department of Veterinary Pathology, Pookode and 17.64% were diagnosed as rabies positive by using direct fluorescent test (d-FAT). Out of all the rabies positive cases, 76.6% were dogs, 9.1% large ruminants, 8.4% cats and 4.5% goats. In dogs, non-descript dogs were highest followed by Labrador, Pomeranian, German Shepherd, crossbred dogs, Rottweiler, Doberman and Spitz. The male dogs contributed about 69.5% of positive cases. Highest number of cases of rabies in animals were found during the winter season (January to March) comprising 33.76% of all the rabies cases.

Dairying as an occupation supports and sustains the livelihood of a large number of rural people in India, especially small farmers, marginal farmers and landless labourers. To study the socio-economic profile of the dairy farmers, Viluppuram district of Tamil Nadu state was purposively selected on the basis of high cattle population. Out of the nine taluks in Viluppuram district, two taluks, namely Viluppuram and Tindivanam taluks were randomly selected from which five villages each were selected. From each of the selected villages, 10 respondents were selected randomly leading to a total of 100 respondents. The findings of the study revealed that half of the respondents were old aged, had secondary to graduate level of education and had agriculture + livestock and wages + livestock + agriculture as their occupation. Majority of the respondents also had large herd size of more than four animals with 11-20 years of dairy farming experience and no participation in training programme. Majority of the respondents had medium level of annual income, economic motivation, mass media exposure, contact with extension agency, risk orientation, proximity to marketing channels, knowledge about improved dairy husbandry practices and decision making behaviour.

Integrated Farming System (IFS) is an efficient way of recycling farm waste or farm by-products. In present study the fishes (Catla, Common carp, Grass carp, Rohu and Silver carp) were cultivated through ostrich feed wastages and cattle manure in six month period. The average fish survival of 86% was observed and it was varied from 84% to 88%. The total weight of fishes harvested was 50.95 kg, 43.71 kg, 42.58 kg, 54.95 kg and 53.76 kg for individual varieties such as Catla, Common crap, Grass crap, Rohu and Silver carp respectively. The average weight of fish at harvesting was 386.0 g, 502.5 g, 507.0 g, 426.0 g and 632.5 g with 64.33 g, 83.75 g, 84.50 g, 71.00 g, 105.42 g average weight gain of fish per month in Catla, Common carp, Grass carp, Rohu and Silver carp respectively. The benefit cost ratio was observed as 2.35 with the net profit of Rs.21,247.50 for 6 months culture period in 0.06 Ha pond area. It was concluded that ostrich and cattle cum fish integration was a suitable and economically viable integrated system in Tamil Nadu.
