ArticleItem Open Access EFFECT OF PROGESTOGEN IN ANOESTRUS EWES DURING BREEDING SEASONQuayam, SA; Devanathan, TG; Iyue, M, et al.,; TANUVASAll treated ewes with intra vaginal device were successfully 1 synchronized at induced oestrus after 36 hours and lambing rate (39.58%) was satisfactory when anoestrus condition of merino ewes was taken into considerationArticleItem Open Access EFFECT OF SEASON OF CALVING AND SEX AND BIRTH - WEIGHT OF CALF ON THIRD STAGE OF LABOUR IN SHE BUFFALOES(1986) Quayam, SA; Neduncheralathan, B; Kathiresan, D; TANUVASStudies on third stage of labour are of economic importance as this process influences the succeeding productive and reproductive efficiency of the dam. The time interval between parturition and shedding of placenta in cows was reported by several authors (Rae et al, 1966, Kadu and Kaikini, 1975 and Agasti et al, 1975)ArticleItem Open Access Leptospirosis In Repeat Breeding And Anoestrus Cattle(1990) Kulasekar, K; Quayam, SA; Ratnam, S; TANUVASSixty one serum samples from cows and buffaloes with problems of repeat breeding and nnoestrum were screened for leptospiral infection by microscopic agglutination test using antigens belonging to six serogrnups : Autumnalis, Canicola, Grippotyphosa, He- bdomadis, Icterohaemorrhagine and Pomo- na. Twenty six out of 61 sera screened revealed antibody rilres ranging from 1:20 to 1:320.

A number of aspects of reproductive wastage in cattle associated with leptospiral infection have been highlighted by studies of naturally infected cattle, which include abortion, premature birth of live calves, still birth, birth of weak term calves which may not survive, decreased milk production and infertility. Ellis and Michna (1977) demonstrated leptospires in placenta from animals which produced live healthy calves as long as 60 days after infection. Many aspects of Leptospirosls in cattle are still inadequately defined. This present study was undertaken with a view to determine association of Leptospiral infection in retained afterbirth.
