ArticleItem Open Access A Clinical case of Pervious Urachus (Urinary Fistula) in a Female Calf(1976) Manickam, R; Sadasivam, P; Kathaperumal, V; TANUVASA case: of pervious urachus (Urinary fistula) is recorded in a heifer calf.ArticleItem Open Access Economic Analysis of Calving Interval of Hungarian Dairy Cattle(2001) Safiullah, AM; Prabaharan, R; Sadasivam, P; TANUVASThe iinpact of various leiLgths of calving iiLterva1 (CI) was airalysed by budgetiiig aibalysis usiirg Quatro spreadsheet program. The lifetime inilk yield and profit per day was used as a basis on various inilk yields, inilk prices aird culliiig strategy either OIL age of cow or lactation. -4nother locally developed biornetrical program pa.ckage was also used to aualyse the distribution of herds using frequency table. Milk production level over different lengths of CZ and average lactatioiial CI in comparisori with each lactation were aiialysed. Greater portioii of herds were distributed within the CZ of 360 days. Annual inilk yield got reduced froin 4500 to 3372 kg as the CI imcreased froin 360 to 450d. Average CZ was fouud to be higher for high yielding cows i i L expectation to have inore lactatioiml yields by keeping thein for loiiger days open. The CI increased as the lactation progressed upto the fourth aird then started decreasing. Increasing CI froin 360 to 420 or 450d resulted in a loss of 0.70 to 2.33 or 0.94 to 3.15 USD. From these findings, it could be concluded that optirnum CZ should be adjusted between 360d and 390d.ArticleItem Open Access Economic Analysis of Calving Interval of Hungarian Dairy Cattle(2001) Safiullah, AM; Prabaharan, R; Sadasivam, P; TANUVASThe iinpact of various leiLgths of calving iiLterva1 (CI) was airalysed by budgetiiig aibalysis usiirg Quatro spreadsheet program.

No statistically significant difference was noticed between the protein content of fresh milk and formalinised milk soon after addition. However, after storage for 7 days at room temperature there was a drastic significant reduction in protein content in the formalinised milk as compared to that of fresh milk. Hydrogen peroxide was found to have no influence in obviating the effect of formalin when protein was determined in milk.ArticleItem Open Access Incidence of gangrenous dermatitis in commercial layers in Namakkal(2005-01) Sukumar, K; Suresh, P; Dorairajan, N; Sadasivam, P; TANUVASThe commercial layer farms (15) in Namakkal area were monitored throughout the year, out of which 7 showed lesions of gangrenous dermatitis. 'The age group involved was between 8 and 16 weeks. The mortality was 10 to 20% of the total flock strength. Flocks with the history of IBD outbreak showed higher mortality compared to others.ArticleItem Open Access PRESERVATION OF MILK BY LACTOPEROXIDASE - THIOCYANATE - HYDROGEN PEROXIDE SYSTEM UNDER LOCAL CONDITION(1989) Dhanalakshmi, B; Sadasivam, P; Jayachandran, T; TANUVASFor the samples of cow milk collected from street vendors and organised dairy farms the increase in keeping quality was meagre when Methylene Blue reduction time (MBRT) was between 3 to 4 hours and less than 2 hours, for the various concentrations tried ie, 25: 15 30: 30, 30 : 45 and 45 : 30 ppm of hydrogen peroxide and thiocyanateProceedingsItem Open Access SEROPREVALENCE OF EGG DROP SYNDROME -1976 (EDS-’76) IN BROILER BREEDERS IN COIMBATORE DISTRICTSuresh, P; Sukumar, K; Dorairajan, N; Sadasivam, P; TANUVASEgg drop syndrome - I976 (EDS-'76) of poullry, u viral disease of significant economic importance has been reported from all pans of world including India. where its sero-prevalence in poultry flocks was first detected by Mohanty et al., (1984). ln Tamil Nadu a wide spread prevalence of EDS-’76 antibody was recorded in 8 districts by Shaw et al., (1995). Since, Coimbatore: district is thickly populated with broiler breeders, a sero-epidemiological investigation on the incidence of EDS-’76 was undertaken by using conventional haemagglutination inhibition (H1) test.ThesisItem Open Access Status, Characteristics And Toxigenicity Of Pathogenic Enterohaemorphagic Escherichia Coli 157:H7 In Milk And Milk Products(Tamil Nadu Veterinary and Animal Sciences University, 2001) Villi, R. Annal; TANUVAS; Sadasivam, PArticleItem Open Access STUDY ON THE SEASONWAR RELATIONSHIP BETWEEN FAT AND SOLIDS NOT FAT CONTENT OF COW MILK(1981) Jayachandran, T; Sadasivam, P; Krishnamurthi, PS; TANUVASThe relationship between fat and solids not fat contents of cro'sbred cow milk samples both in the morning and evening are found to be positively correlated and statistically highly significant. The regression equation derived in this study showed a difference in the numerical constant and fraction between morning and evening samples invariably in all seasons
