ArticleItem Open Access THE COMPARATIVE EFFICACY OF CLOPROSTENOLAND THERAPEUTIC INTRA UTERINE INFUSION OF POVIDONE IDODINE ON SUBCLINICAL ENDOMETRITIS AND SUBSEQUENT CONCEPTION RATE IN JERSEY CROSS BRED COWS(2019-04) Kavitha, K; Nithin, AG; Sarath, T, et al.,; TANUVASThe present study consists of Jersey cross bred cows brought to MadrasVeterinary College-Teaching Hospital, determined to be normal, based on absence of abnormal uterine discharge at the time of estrus. Thorough clinical examination, rectal examination and laboratory evaluations viz. White SideTest (WST), Leucocyte Esterase strip test and Endometrial Cytology (EC) were performed to con"rm subclinical endometritis. The cows under study were divided into two groups; GroupAcows (n=6) treated with Inj. Streptopenicillin 5g total dose (IM) for three consecutive days followed by Inj. Cloprostenol 500μg (IM) on the seventh day of the cycle. Group B cows (n=6) treated with Inj. Streptopenicillin 5g (IM) along with 20ml Povidone Iodine diluted with 20ml sterile water, intra uterine, for three consecutive days. All the treated cows were subjected to laboratory re-evaluations and inseminated on the following estrum. Improved conception rate was observed in Group A (83.33%) compared to Group B (66.66%) which indicates the immunomodulatory effect of cloprostenol. However, no statistical difference in conception rates were observed between the treatment groups, which may be due to smaller sample size, thus further research is warranted.ArticleItem Open Access Dystocia due to Diprospus Parapagus fetus and its Successful Delivery through C- Section in a Non-Descript Goat(2019-04) Kavitha, K; Monica, G; Sarath, T, et al.; TANUVASThe present paper reports the successful delivery of a dicephalus monster fetus through Caesarean section and the features of dicephalic fetus in non-descript goat as recorded.ArticleItem Open Access EFFECT OF BREED AND SEX ON SERUM BIOCHEMICAL PARAMETERS IN WHITE PEKIN AND INDIGENOUS DUCKS OF TAMIL NADU(2020-04) Kavitha, K; Raj Manohar, G; Vairamuthu, S; Ramamurthy, N; TANUVASThe present work was undertaken to evaluate the effect of breed and sex on Serum Biochemical profile in White Pekin and Indigenous ducks of Tamil Nadu at Post Graduate Research Institute in Animal Sciences (PGRIAS), Kattupakkam. A total of eighty number of ducks comprising 20 male and 20 female each in White Pekin and Indigenous ducks of Tamil Nadu were reared under standard managemental conditions. Once in every 4 weeks, blood was collected from these ducks individually from 20th week onwards for the duration of two months. The parameters such as Total Serum Protein, Serum Albumin, Serum Globulin, Serum Calcium, Serum Cholesterol and Serum Triglyceride were estimated. The results revealed that the White Pekin ducks had significantly (P<0.01) higher Total Serum Protein, Serum Albumin, Serum Globulin while Serum Triglyceride level was significantly (P<0.01)higher in Indigenous ducks of Tamil Nadu. Among sexes, female Indigenous ducks had significantly (P<0.05) higher Total Serum Protein, Serum Globulin than male ducks. Serum Cholesterol and Serum calcium was significantly higher in female White Pekin and Indigenous ducks of Tamil Nadu than the male ducks. Hence, it was concluded that breed and sex had significant effect on Serum Biochemical parameters in White Pekin and Indigenous ducks of Tamil Nadu.ArticleItem Open Access Effect of Different Doses of PMSG for Synchronisation of Estrus in Progesterone Primed Goats(Excellent Publishers, 2018-08) Kavitha, K; Joseph, Cecilia; Sarath, T; Pugazharasi, C; TANUVASThe present study was aimed to evaluate the efficacy of estrus response in synchronized does using intravaginal sponges containing 350 mg progesterone (AVIKESIL-S) in situ for 11 days, 125 μg Cloprostenol, on day 10 and PMSG at two does of 200 IU (Group I) or 400 IU (Group II) on day 11 at the time of sponge removal, in non-descript does under field conditions. The percentage of estrous response and duration of estrus were observed to be 70, 100 and 100; 40.93 ± 1.49, 42.20 ± 1.32 and 49.50 ± 0.94 in control, Group I and Group II respectively. Pregnancy verification was done 40 to 45 days post mating by ultrasound examination and the conception rate in control, Group I and Group II was 52.40, 63.33 and 66.67 respectively. Follicular study, pre and post treatment of PMSG in the treatment groups indicated an increase in daily growth rate of follicles from 0.05 to 0.09 mm with the increase in dose of PMSG from 100 IU to 400 IU.ThesisItem Open Access ESTRUS INDUCTION AND FECUNDITY IN NON-DESCRIPT GOATS WITH DIFFERENT DOSES OF PMSG(2018) Kavitha, K; Joseph, Cecilia; Sarath, T; Senthilkumar, TMA; TANUVASReproductive performance is one of the important economic traits in goats. Higher pregnancy rates, birth weight and rapid recovery of doe’s weight after parturition are important reproductive characteristics deciding the benefits of goat rearing. Among various reproductive techniques, synchronization of estrus is recent approach to augment fertility and fecundity in goats. A total of 725 does were screened at various villages of Kanchipuram district using ultrasound examination for non pregnancy and one fifty non-descript goats were selected and randomly divided into five groups – groups I, II, III, IV and V with 30 does in each group. The first group was considered as control and no treatment was given. In group II, 30 does were treated with progesterone intra-vaginal sponges (AVIKESIL–S) containing 350 mg progesterone, for 11 days and 125 μg of cloprostenol (i.m.) on day 10. In groups III, IV and V besides intravaginal sponges (AVIKESIL–S) in situ for 11 days and 125 μg Cloprostenol (i.m.) on day 10, 100 I.U., 200 I.U. and 400 I.U. of PMSG was administered on day 11 at the time of sponge removal, in the three groups respectively. Behavioural and physiological signs of estrus were observed in all the does. Estrous induction, intensity of estrus based on behavioural and physiological signs of estrus, duration of estrus, conception rate and fecundity rate were recorded for all the does.OtherItem Open Access ESTRUS INDUCTION AND FECUNDITY IN NON-DESCRIPT GOATS WITH DIFFERENT DOSES OF PMSG(2019-12) Kavitha, K; Joseph, Cecilia; Sarath, T; et al.; TANUVASThe present study aimed to evaluate the efficacy of estrus response (behavioural and physiological signs), conception and fecundity rate in synchronized does using intravaginal progesterone sponges (AVIKESIL–S) in situ for 11 days and 125 μg Cloprostenol (i.m.) on day 10, followed by intramuscular injection of 0 I.U. (GroupI), 100 I.U.(GroupII), 200 I.U.(GroupIII) and 400 I.U.(GroupIV) of PMSG (Pregnant Mare Serum Gonadotropin) on day 11,at the time of sponge removal. Does without any hormonal treatment was considered as control. All does were let for natural service by proven bucks. The percentage of does in estrusin control, GroupI, GroupII, GroupIII and GroupIV were 70, 80, 100, 100 and 100 per cent, respectively. The expression of physiological signs were more pronounced and significantly (P<0.01) higher in Groups II, III and IV. The mean (±SE) duration of estrus was 40.93±1.49, 41.03±1.33, 42.20±1.32, 46.27±1.47 and 49.50± 0.94 hrs in control, Group I, Group II, Group III and Group IV, respectively. The duration of estrus was significantly (P<0.01) longer in does of Group IV when compared to control and other groups. The conception rate of control, and groupsI, II, III and IV was 52.40, 54.16, 63.33, 73.33 and 66.67 per cent, respectively and a higher kidding rate was observed in Group III. The fecundity rate was found to be significantly higher in Groups III (2.14) and IV(2.15),respectively compared to GroupsI(1.62) and II(1.58). Thus cost effective estrus synchronization can be achieved with 200 I.U. PMSG in progesterone primed non-descript local goats with tight synchrony, improved conception, kidding and fecundity rates under field conditions.ThesisItem Open Access EVALUATION OF AYURVEDIC MEDICINE PROCESSING UNITS IN UTTARA KANNADA DISTRICT (KARNATAKA)(University of Agricultural Sciences, Dharwad, 2000) Kavitha, K; Khan, H S SIn the present day context, it can be stated that Avurveda is very much alive and is a unique system of medicine widely practiced in Hindustan penensula. In recent years, it h a s attended much attention in the economically developed countries such as (of) Europe, USA and Japan. The present study was aimed to assess the. p erformance of Ayurvedic medicine processing units in Uttara Kannada district (Karnataka). The objectives were to document the agro-processing units / industries in different taluks of Uttara Kannada district, to study the inves tment pattern organisation structure, cost involved in procurement and processing, cost and return structure, marketing channe ls and costs, business performance and the problems faced by the Ayurvedic medicine proces s ing industry. Tabular analysis, bus ine s s ratios and comparative rating method were employed to analyse the above objective. The fixed capital inve s tment was high on buildings and land. All the three units taken for the s tudy followed line organization t^pe of structure. The quantity of raw materials procured by all the three units was more through pattern II (dealers i.e., 2 ,2 5 5 .5 0 kg, 2 ,6 5 4 .5 0 kg and 4 ,5 7 2 .9 1 kg, respectively). No cost was involved in procuring the raw materials through pattern I but through pattern II, transport and handling charges were higher i.e. 6 3 .0 7 per cent in unit I and 6 6 .7 5 per cent in unit III. In all the three units. Just in time principle of procurement was followed. The study on cost involved in processing of Ayurvedic medic ines by all the three units revealed the higher requirement for packing material cost (85.48 per cent in unit I, 67.33 per cent in unit II and 7 8 .1 2 per cent in unit III) followed by wages, utilities and preservatives. The cost of production of Ayurvedic medicines was high in unit I (Rs.46,801.83) followed by unit III (Rs.4 0 ,7 3 6 .2 ) and unit II (Rs.21 ,2 9 6 .7 0 ) , in which the cost of proc e s s ing per batch of each product was observed to be high. The profit gained at an overall level by unit I, unit II and unit III was in the order of Rs .0 .7 6 , Rs.0.90 and Rs .0.56 respectively on an every rupee of investment. Unit I marketed their products only through dealers while unit III marketed through their hospi tals located at different places. Unit II marketed 6 2 .3 9 per cent through dealers and 37.61 per cent through its hospital located near the proces s ing unit. The cos t of marketing through dealers was highest due to the high commis s ion charges (5%) and sales tax paid by the units. The competition that exists in the market, the tax levied on the raw materials and finished products and the procurement price incurred by the units wa s considered to be the prioritized problems in Ayurvedic medicine proces s ing industry.ThesisItem Open Access Management of damping off and improvement of growth in chilli with native species of arbuscular mycorrhizae(Department of Plant Pathology, College of Agriculture, Vellayani, 2001) Kavitha, K; KAU; Meenakumari, K SManagement of damping off, the most destructive disease of chilli both 111 nursery and main field incited by Pythium aphanidermatum (Edson) Fitz. using native AMF was attempted in the present investigation. Out of nine native AMF and one identified culture (Glomus mosseae) screened, the cultures Ms and M9 were found effective for suppression of damping off and growth improvement in chilli. Application of AMF inoculum in the nursery furrows along with chilli seeds was very effective for rapid and easy colonization of AMF. Likewise application of AMF inoculum at the rate of 850 g m-2 was selected as the economic dose for achieving satisfactory colonization of AMF. Azospirillum spp. were isolated from chilli roots collected from different locations of Thiruvananthapuram district. The in vitro nitrogen fixing capacity of the isolates ranged between 11.2 and 20 mg N s' of malate and IAA production between 21 and 55 ug mrl. Six best isolates which performed well under in vitro screening were selected an-d subjected to in vivo screening for growth, biomass production and yield in chilli. The isolates Az-l and Az-2 which performed well both under in vitro and in vivo screening were selected for further studies. Based on the characterization studies it was found that the isolate Az-l is related to Azospirillum lipoJerum and Az-2 is similar to Azospirillum brasilense. The isolate Az-l grew well at pH 5,6 and 7 whereas the isolate Az-2 grew well at pH 6 and 7. In the study on the interaction of native AMF and Azospirillum on damping off disease suppression, pre-inoculation of chilli seedlings with M9 culture alone recorded the least disease incidence. Eventhough dual inoculation of AMF and Azospirillum could suppress the damping off, Azospirillum had no direct effect on disease suppression. However dual inoculation of AMF and Azospirillum (M9A2PO) significantly increased the growth, biomass production and yield in chilli. The present study forms the first report of the synergistic effect of AMF and Azospirillum for the management of damping off and growth improvement in chilli. The present investigation emphasizes the importance of pre-inoculation of AMF in the chilli nursery as a prophylatic measure to prevent pathogen attack. The technology of combined inoculation of AMF and Azospirillum could be recommended for adoption by the vegetable farmers. Eventhough the present study was carried out in chilli, the same cultures could be recommended for all transplanted solanaceous vegetables after confirming the results through field trials.PresentationItem Open Access Quantification and initial profiling of salivary and cervico vaginal fluid proteins in murrah buffalos during estrus and proestrus using sodium dodecyl sulfate-polyacrylamide gel electrophoresis(2020-02) Kavitha, K; Suresh Kumar, R; Krishnakumar, K; Sarath, T; Vijayarani, K; Arunmozhi, N; Balasubramaniyan, S; Leena, KB; Abhinaya, K; TANUVASSaliva and cervico vaginal fluid (CVF) are considered good non invasive biomarkers for detection of estrus in buffalo as external signs are not significant in these animals. Based on the linkage between salivary proteins and estrus, the present study was aimed to profile the salivary and CVF proteins in Murrahbuffaloes (atproestrus and estrus) using single dimension (1-D) sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE).It was observed that the saliva collected from sevenestrus buffalo had proteins with the molecular weight of 26kDa, 31kDa, 50kDa, 70kDa and 76kDa whereas saliva from eight proestrus buffalo had proteins with molecular weight of 48kDa, 62kDa, 70kDa and 75kDa. Based on published data by Shashikumaret al., (2018) the proteins in the estrus and proestrus correspond to short palate lung and nasalepithelium carcinoma-associated protein 2B (26.5kDa), tRNA-methyltransferase catalytic subunit TRM61A, CCDC85A protein (50kDa), Heat shock 70kDa protein (70kDa), Testin (48kDa), Max-binding protein MNT and Rho guanine nucleotide exchange factor 37 (76.1kDa) or Serine/threonine-protein phosphatese 2A 65kDa regulatory subunit A beta isoform (76.7kDa). Molecular weight of proteins observed in the CVF collected during estrus (n=4) where predominantly of 70kDa and 78kDa which correspond to Heat shock 70kDa protein and Receptor-type tyrosine-protein phosphatase epsilon (78.49kDa) respectively based on the published data by Muthukumaret al.(2014). Thus these findings provide a lead for further analysis and evaluation of the proteins for estrus detection in buffalo.
