OtherItem Open Access Pathological effect of dietary ochratoxin A and Eimeria tenella infection alone and in combination in broilers(TANUVAS, Chennai, 2004-09) Muthusamy, K.; George, V. Titus; Balasubramaniam, G.A.; Vairamuthu, S.; TANUVASExperimentally, ochratoxicosis and coccidiosis were induced singly and in combination in 6 groups of broilers each consisting of 25 chicks. Ochratoxicosis was induced by feeding with dietary ochratoxin A (OA) at a concentration of 0.5 and 1 ppm tor 23 days. Coccidiosis was induced by inoculating 50,000 sporulated oocysts of E. tenella as 14th day.OtherItem Open Access Experimental Transmission Of Hydropericardium Syndrome By Different Routes In Broiler Chicken(TANUVAS, Chennai, 2004-06) Vairamuthu, S.; Manohar, B. Murali; George, V. Titus; TANUVASHydropericardium syndrome (HPS) is primarily a disease of broiler chickens. The disease was first recorded on commercial broilers in India during the year I994 (Sreenivas Gowda and Sathyariarayana, 1994). The disease mainly affects broiler chickens of 3-6 weeks old age and mortality ranges 30-50% during natural outbreaks (Ravi kumar et al., I998) in experimental infection mortality upto 97% has been recorded (Roy et al., 2004).OtherItem Open Access Effect of Supplementation of Vegetable Oils in Feed of Broiler Rabbits(2018-04) Arulmuthumathavan, M.; Ramesh, V.; Ramakrishnan, S.; Senthilkumar, S.; Sivakumar, K.; TANUVASA study was conducted on 48 weaned Soviet Chinchilla rabbits to evaluate the effect of supplementation of vegetable oils with respect to growth and reproductive performance. The rabbits were divided into four groups of twelve each. First group (T1) fed on basal diet alone, second group (T2) fed on basal diet supplemented with rice bran oil @ 2 per cent level, third group (T3) fed on basal diet supplemented with palm oil @2 per cent level and fourth group (T4) fed on basal diet supplemented with both rice bran oil and palm oil each @ one per cent level.OtherItem Open Access Early weaning and Concentrate supplementation on body condition score of Mecheri Ewes and Lambs(2017) Santhoshkumar, R.; Ramesh, V.; Sivakumar, K.; Thiruvenkadan, A.K.; TANUVASThis study was carried out on Mecheri lambs and ewes at Mecheri Sheep Research Station. A total of 72 Mecheri lambs were divided into three treatment i.e.. weaned at 90 days (T1), 75 days (T2) and 60 days (T3) with 24 lambs in each treatment. Each treatment was again divided into two groups, based on the concentrate supplementation level i.e., 1 and 1.5% of body weight and all lambs were maintained under semi-intensive system of management.OtherItem Open Access Role of Essential Oils in Broiler Chicken Production(2018-07) Rajkumar, K.; Hudson, G.H.; Boopathi, V.; Arulprakash, M.; TANUVASThe Strict Legislative ban over use of antibiotics as feed additive has lead to the research on alternative to antibiotics. Indiscriminate use of antibiotics leads to proliferation of antibiotic insensitive bacteria, thus posing a threat to human health.OtherItem Open Access A Comparative Study Of Serum Gelatinase in Normal and Tumour Affected Dogs Through Gelatin Zymography(2016-05) Krupakaran, R.P.; Balamurugan, T.C.; Shoba, A.; Lakshmi, R.D.; Perumal, P.; TANUVASA comparative study was undertaken to assess the gelatinase activity in the sera of normal and tumour affected dogs through gelatin zymography. In gelatin zymography, the presence of three major bands 220, 92kDa of MMP-9 and 72kDa of MMP-2 were confirmed. The intensity of active form of 92kDa of MMP-9 was comparatively thinner in sera of tumour affected than in normal dog. The intensity of 220, 92 kDa of MMP-9 were 3-4 times higher than that in normal dog. But the intensity of 72kDa MMP-2 band was slightly higher in sera samples of tumour affected than normal one. Latent form of 220 kDa band was comparatively thinner than 92kDa of MMP-9. The latent form 72 kDa of MMP-2 was observed in the serum of normal dog samples. There was more up-regulation of MMP-9 mediated through MMP-2 activity was observed in tumour affected dog. It was concluded that the intensity of MMP-9 and MMP-2 was higher in tumour affected than in normal dogs and it could be used as a potential early diagnostic method/marker in the determination of canine tumour progression.OtherItem Open Access Detection of Matrix Metallo Proteinase-2 in Layer Chicken(2016) Krupakaran, R.P.; Balamurugan, T.C.; Lakshmi, D.; Sheeba, A.; Perumal, P.; TANUVASOtherItem Open Access Green Synthesis of Metallic Nanoparticles using Aqueous Plant Extract and their Antibacterial Activity(2017-06) Saranya, S.; Eswari, A.; Gayathri, E.; Eswari, S.; Vijayarani, K.; TANUVASOtherItem Open Access Expression of mRNA encoding leukaemia inhibitory factor (LIF) and its receptor (LIFRβ) in buffalo preimplantation embryos produced in vitro: markers of successful embryo implantation(2012-08) Eswari, S.; Saikumar, G.; Sharma, G. Taru; TANUVASThe objective of this study was to evaluate the effect of supplementation of recombinant leukaemia inhibitory factor (LIF) in culture media on blastocyst development, total cell number and blastocyst hatching rates and the reverse transcription-polymerase chain reaction analysis of preimplantation buffalo embryos to determine whether they contain the LIF-encoding mRNA and its beta receptor (LIFR ) genes in different stages of preimplantation buffalo embryos. Cumulus–oocyte complexes retrieved from slaughterhouse buffalo ovaries were matured in vitro and fertilized using frozen buffalo semen. After 18 h of co-incubation with sperm, the presumptive zygotes were cultured in modified synthetic oviductal fluid without (control) orwith rhLIF (100 ng/ml). Therewas no significant difference in the overall cleavage rate up to morula stage however the development of blastocysts, hatching rate and total cell numbers were significantly higher in the LIF-treated group than control.
