ThesisItem Open Access “STUDIES ON SOME BIOLOGICAL ASPECTS OF THE BLACK BANDED TREVALLY, SERIOLINA NIGROFASCIATA (RUPPELL, 1982) ALONG THE MANGALURU COAST”(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018) KALAVATHI N.R.,; MANSING NAIK)The black-banded trevally, Seriolina nigrofasciata found In indo-west pacific, from eastern coast of Africa to Australia, north to southern Japan. Seriolina nigrofasciata (order: perciformes, family : Carangidae ) is a non-schooling carangid fish which occurs at the depth from 20-150 m and is commonly found in offshore reefs over the continental shelf on rocky bottom. This species is also called as “black banded king fish or butter fish” and locally called as “Neyyi meenu”. The present study is based on the observation of a total 627 individuals ranging in size from 15 to 63 cm total length (TL) comprising 280 males and 347 females. The length-weight relationship for male was W= 0.0179L2.9596 and for female W=0.0186L2.9156 . The relative condition factor (Kn) values for male and female varied from 0.9727 and 1.3307 respectively. Analysis of the gut content indicated that fish is carnivore and the diet was composed of Semi-digested matter 68.04 %, teleost 20.80 %, molluscans 16.66 %, crustaceans 3.49 %. The size at the first maturity for male and female appeared at a length of 36 cm and 39 cm TL respectively. The sex-ratio of male:female was found to be 1:1.23 in the commercial catches, showing dominance of female in the population. The Ganado-Somatic Index values ranged from 0.2149 to 2.1769 in male and in case of female, it fluctuated between 0.2342 to 3.9696. The fecundity ranged from 1,92,295 to 7,60,248 eggs with an average 5,02,906 eggs per individual . The ova diameter ranged from 0.01 to 0.5mm. The maturity stages of Seriolina nigrofasciata indicated that this species is a annual single spawner during November to febraury. Proximate composition revealed that fish muscle has 74.03 % to 83.12 % moisture, 14.58 % to 21.87 %. protein, 0.57 % to 3.66 % fat, and 0.86 % to 1.64 %. of ash.ThesisItem Open Access ANTHROPOGENIC INFLUENCE OF MARVOOR VENTED DAM ON HYDROBIOLOGY OF GURUPUR RIVER AND ESTUARY, MANGALORE(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018) CHANNESH G. V; GANGADHARA GOWDA)Anthropogenic effects and processes influences physico-chemical characteristics of aquatic environments and biodiversity. Continuous influx of raw sewages and discharge of effluents into Gurupur river water systems lead to impair the water quality and biodiversity in the Marvoor vented dam and hydrobiology Gurpur River and estuary, Mangaluru, Dakshina Kannada, Karnataka. The present investigation was carried out for twelve months in selected stations (S1 to S7) S1, S2 & S3 in the Vented dam fresh water zone and S4, S5, S6 & S7 in brackish water zone. Study revealed that the anthropogenic activities have made impacts on water quality (Temperature pH, DO, BOD and nutrients especially Ammonia –Nitrogen; sediment (Temperature, pH, Organic matter and texture); plankton (Phytoplankton and Zooplankton); benthos and fishes. Among the water quality parameters water temperature, DO, BOD, salinity, pH and nutrients showed wide range of fluctuations in the both fresh water and estuarine water zones, due to discharge of domestic raw sewage and industrial effluents and habitat destruction due to sand excavation. Presence of dominance of species phytoplankton belong to Chlorophyceae and Chrysophyceae and zooplankton dominated by copepods followed by rotifers indicated the eutrophic environment. Further, microbiological analysis showed that water is contaminated by total and faecal coliforms. Hence, the water is not safe for human consumption. Physio-chemical parameters of water and sediment have altered the occurrence, abundance and distribution of plankton, macro benthos and fish fauna. Results indicated that entry of untreated sewage and industrial wastes have to be treated and before released into the Gurupur river estuary. The water in the vented dam is unsafe hence, water should be treated before supplied to local population in the region. The Gurupur river ecosystem should be properly managed and conserved for future needsThesisItem Open Access TROPHIC INTERACTION IN COMMERCIALLY EXPLOITED DEMERSAL FINFISHES WITH EMPHASIS ON ONTOGENIC DIET SHIFTS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018) BHAVANJALI M.R; MRIDULA RAJESHTrophic interactions in seven commercially exploited marine demersal finfishes of Karnataka were studied to understand the trophic organization with an emphasis on ontogenic diet shifts and trophic overlap. In total, 4723 stomachs were examined of which 73 prey items were identified. Crustaceans and fishes formed the major prey item. Based on cluster analysis of predator feeding similarities and ontogenic diet shift within each predator, two major trophic guilds were identified. The first guild of ‘crustacean feeders’ included all size groups of Nemipterus japonicus, N. randalli, O. cuvieri and Priacanthus hamrur. The second trophic guild, ‘piscivores’, was mainly made up of larger size groups of all predators and all size groups of Saurida tumbil and S. undosquamis. The mean diet breadth and mean trophic level showed a strong correlation with ontogenic diet shift. TROPH values ranged from 3.4-4.6 for species indicating carnivorous diet pattern of the species. All the species were carnivores and the extent of carnivory increased with ontogeny. It is clear from the present study that most of the species when they were young preferred crustaceans, other invertebrates and smaller fishes but the preference changed for teleosts and other carnivores as they grew in size and age. A seasonal variation in the diet pattern observed was due to variations in prey abundance. Trophic network analysis showed maximum prey in Trophic level III and any alterations due to ecological or anthropogenic activities affecting the prey would result in alterations in community dynamics of the predators.ThesisItem Open Access THERMAL PROCESSING OF FISH STEAKS (PANGASIUS HYPOPHTHALMUS) IN CURRY MEDIUM USING RETORTABLE POUCHES(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018) PATIL SHWETA MOHAN; B.MANJANAIKThe ready to eat Fish steaks in curry (Malvani style) was prepared and packed in 3 layer (3-ply) laminated retort pouches, processed in a steam/ air mixture over pressure retort at 121 ᵒC for two different Fo values of 8.6 and 9.7 min. The time temperature data was collected during thermal processing using Ellab sterilization monitoring system (ELLAB, Denmark). The texture profiles such as hardness, springiness, gumminess, cohesiveness, and chewiness decreased as the Fo value increased. The total process time taken to reach Fo values of 8.6 and 9.7 min was 35.85 and 39.24 min respectively. Cook value and total process time found to be increased with increasing Fo value. Based on the commercial sterility, sensory evaluation and texture profile analysis, Fo value 9.7 min and cook value of 92.71 min with a total process time of 39.24 min at 121.1 ᵒC, was found satisfactory for the development of ready to eat Pangasius fish steaks curry in retort pouches.ThesisItem Unknown EFFECT OF FRESH BANANA PLANT WASTE AND ITS SILAGE ON DRY MATTER INTAKE, NUTRIENT DIGESTIBILITY AND RUMEN PARAMETERS IN OSMANABADI KIDS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR- 585 401, 2015-01-01) SHIVARAM N. PATIL; T. THIRUMALESHGrowth trial of twelve weeks duration comprised two phases of six weeks each was carried out on 15 kids (8-11 months; 16 kg body weight) which were divided into three groups of 5 kids each and were fed either control diet (T1), fresh banana plant waste (FBPW) plus CFM (T2), and fresh banana plant waste silage (FBPWS) plus CFM (T3) in Phase-I. In phase-II, for all the treatment groups red gram straw (RGS) was incorporated to meet the deficit DM requirement. The total DMI (g/d) in T1, T2 and T3 groups in phase-I and II were 504.9 and 533.9; 324.1and 558.1; 395.3 and 445.5, respectively which were significantly (P<0.01) different among the groups. Significant (P<0.01) difference was observed among treatment groups in CP, NDF and ADF intake. Similarly, no difference was observed in weight gain and also in nutrient digestibility in phase-I where as digestibility of DM, OM, CP and NFE were significantly (P<0.01) different in phase-II. The DCP and TDN values of the diet in both the phases were significantly (P<0.01) different. The rumen parameters like pH, TVFAs, NH3-N, TN, TCA-N and SN were estimated from the rumen fluid collected at the initial and final of the experiment were within normal range even though some difference was observed in few rumen parameters. It was concluded that FBPW and its silage supported for maintenance level of requirement, inclusion of RGS in the diet supported higher weight gain.ThesisItem Open Access SEROEPIDEMEOLOGICAL ASPECTS OF INFECTIOUS BOVINE RHINOTRACHEITIS IN BUFFALOES OF NORTH-EASTERN REGION OF KARNATAKA(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2015-06-01) SHARANAGOUDA.B.M; N.A. PATILTotally 370 serum samples from the four districts of North-Eastern region of Karnataka were screened for IBR seroprevalence viz., Vijaypura, Bidar, Kalaburgi and Yadgir districts using ELISA kit .Overall prevalence of IBR in this region irrespective of farming system was found to be 36.49%.In buffaloes less than five years of age overall prevalence was found to be 8.92% and it was 27.57% in buffaloes more than five years age. Among the buffaloes having the history of abortion overall prevalence was found to be 9.19%. District-wise seroprevalence was highest in Bidar district (51.09%) followed by Kalaburgi (43.48%),Vijaypura (35.87%) and lowest in Yadgir district (15.96%). Among the different farming sector higher prevalence was found in organized farming sector. Between the districts the prevalence of IBR was highest in Bidar district organized sector compared to other districts. Among the unorganized sector highest seroprevalence was in Kalaburgi district. No significant difference of seroprevalence of IBR was seen among less than five years age buffaloes in different districts but lowest seroprevalence was in Yadgir district. Seroprevalence of IBR in more than five years age was more compared to less than five years age group. Highest prevalence of IBR in more than five years age group was seen in Bidar district. Prevalence of IBR in buffaloes with history of abortion was highest in Bidar district and no significant difference was seen in seroprevalence of IBR between districts. The higher prevalence of IBR in organized farming sector may be attributed to poor managemental practices observed in this region during the study.ThesisItem Open Access PATHOLOGY OF PNEUMOENTERIC INFECTIONS OF POULTRY IN AND AROUND BIDAR(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR-585401, 2005-09-01) MANJUNATHA S. S.; D.T.NAIKThe present investigation was taken up to study the prevalence of pneumoenteric infections of poultry in and around Bidar. The study was designed to find out the probable disease conditions causing pneumoenteric lesions, based on gross and histopathological findings. During the present study, a total of 500 samples comprising of trachea, lungs and intestines were examined for the presence of either pneumonic or enteric lesions. A systematic screening of these samples revealed various pathological changes on gross and histopathological examinations. The results indicated 45.8 per cent pneumonic infections and 33.8 per cent enteric infections in the present study. The proportional disease specific prevalence of various pneumonic conditions of poultry in the present study revealed higher prevalence rate of pneumonia due to bacterial agents (46.29%), followed by miscellaneous agents (27.95%) and viral agents (25.76%). The proportional disease specific prevalence of various enteric infections of poultry in the present study indicated higher prevalence of parasitic enteritis (48.52%) when compared to bacterial (35.5%) and viral enteritis (15.98%).ThesisItem Open Access PREVALENCE OF YOKE GALL IN BULLOCKS- ITS MANAGEMENT(KVAFSU, Bidar, 2005-06-01) MANJUNATH PATIL; B.V. SHIVAPRAKASHSTUDY ON PREVALENCE OF YOKE GALL, ITS MEDICAL AND SURGICAL TREATMENT IN BULLOCKS Manjunath Patil August-2005 Dr. B. V. Shivaprakash Major Advisor ABSTRACT Prevalence of yoke gall was studied under three different situations i.e., among clinical cases, among animals disposed for sale and slaughter. Classification and evaluation of eight different treatments was made in 57 clinical cases of yoke gall. Prevalence of yoke gall was studied in nine different locations of Karnataka State among clinical cases presented for five retrospective years from 2000 to 2004. Out of 2,61,882 total cases, 70,896 were suffering from different surgical disorders. Out of these, 2,081 cases had yoke gall with an overall prevalence of 0.79%; and prevalence among surgical cases was 2.94%. Out of 2,225 cattle and buffaloes disposed for sale, 38 bullocks were affected with yoke gall showing the prevalence of 1.71%. Out of 1,148 animals disposed for slaughter at Bangalore slaughter house and Chitaguppa slaughter house, 33 bullocks were found affected with yoke gall showing the prevalence of 2.98%. The prevalence of acute yoke gall was maximum (40.13%) in clinical situation; subacute yoke gall was maximum (52.63%) among the animals disposed for sale; and the chronic was maximum (53.06%) among the animals disposed for slaughter. The prevalence was maximum in rainy season (46.23%) followed by winter (31.43%). The prevalence was maximum in the bullocks of 6 to 8 years of age (48.42%). The prevalence was maximum in males (88.42%). Based on clinical and hisptopathological features a standard list of classification was given to yoke gall. Haematobiochemical and histological features of each type were documented. Fifty seven bullocks were divided into eight groups for the evaluation of treatment. In group I, diclofenac sodium injection and topical application of Khand ointment (turmeric and lime juice) were given. There was no reduction in swelling of acute and subacute yoke gall during the first 15 days and only 25% reduction was seen after 30 days. In group II, diclofenac sodium injection and topical application of Khand ointment and dimethyl sulfoxide liquid were used. Initially no response and after one month only 25% reduction was seen in these bullocks. In group III, only topical application of dimethyl sulfoxide was employed. Response was negligible during initial 15 days and slight reduction (25%) was seen after 30 days in bullocks with acute and subacute yoke gall. In group IV, intravenous dimethyl sulfoxie @ 1.0 g/kg b.wt. resulted in 50% of reduction of acute yoke gall on third day, 75% reduction on seventh day, 90% reduction on 15 th day and complete reduction on 30 th day. In group V, dexamethasone injection was given directly into the swelling. The acute yoke gall showed 50% reduction in swelling on third day, 75% on seventh day and almost complete reduction on 30 th day. In group VI, herbal treatment using paste of root of Triumfetta rotundifolia and leaves of Dregia volubilis were applied. The acute yoke galls showed 25% reduction on third day, 50% reduction on seventh day and complete absorption of fluid by 30 th day. The response was partial for subacute yoke gall and nil for chronic fibrosed yoke gall in groups IV, V & VI. In group VII, surgical drainage of acute yoke galls by stab incision resulted in immediate reduction but required second incision due to reaccumulation. In group VIII, surgical excision was followed in nine bullocks with chronic yoke galls which resulted in 100% improvement. There was no change in haematological values before and after treatment. There was slight increase in SGPT level and marked increase in LDH levels before and 30 days after treatment in all the groups.ThesisItem Open Access EFFECT OF SUPPLEMENTATION OF OATS’ (Avena sativa) POWDER ON THE QUALITY CHARACTERISTICS OF PROBIOTIC YOGHURT(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-07-01) RAKSHITH KUMAR, S.; JAYASHRI P. HIREMATHValue addition of yoghurt with functional ingredients like probiotics and oats (Avena sativa) enhances nutritive and bioactivities of yoghurt. Hence, oats has gained significance due to its β-glucan and antioxidant components. The prepared raw oats‟ powder showed moisture, carbohydrates, fat, protein, ash & crude fibre at 5.31, 61.95, 6.86, 16.34, 1.49 & 8.05 % respectively whereas, the corresponding values were 2.64, 64.01, 6.96, 16.82, 1.50 & 8.07 % respectively in roasted oats‟ powder. Among the levels of yoghurt culture (1.5%, 2% & 2.5%) and probiotic culture B. bifidum (3%, 4% & 5%), the levels of 2 % & 4 % scored maximum respectively. Probiotic yoghurt optimized exclusively with raw oats' powder and roasted oats‟ powder separately (0.5%, 0.75% & 1%), showed 0.5% of raw and roasted oats‟ powders can be incorporated. In-vitro antioxidant activity performed by DPPH radical-scavenging method shown by raw oats‟ powder yoghurt and roasted oats‟ powder yoghurt were 88.79% & 92.71% respectively, which were higher than the control (73.3%). Both optimized experimental samples were effective in significantly lowering the blood glucose level of experimental rats upon feeding for a period of 5 weeks compared to control. Storage studies at 5±1˚C revealed that the product retained acceptability up to 9 days. During storage, there was an increase in % titratable acidity, % FFA and % soluble nitrogen. The viability counts of B. bifidum were higher than the control due to prebiotic effect of β-glucan. Hence, the present study was aimed to explore bioactivities of yoghurt supplemented with oats‟ powder.
