Occurrence of Postpartum Anestrus and Estrus Behaviour in Hormonal Treated Buffaloes of Jabalpur

Abstract

The present study was conducted during June to December, 2022 at the Department of Veterinary Gynaecology and Obstetrics, College of Veterinary Science and Animal Husbandry, Nanaji Deshmukh Veterinary Science University, Jabalpur, Madhya Pradesh, India to study the occurrence of postpartum anestrus and compare the intensity of estrus in anestrus and estrus induced buffaloes of Jabalpur (M.P.). A total of 120 postpartum buffaloes (5–10 years of age) reared under field conditions in the Jabalpur district of Madhya Pradesh were surveyed. The buffaloes with a history of not showing signs of estrus for 60 days or more postpartum were considered as open animals for the study of the occurrence of postpartum anestrus. Gynaeco-clinical examination was also carried out to know the status of ovaries (presence of follicle or corpus luteum). These animals were randomly divided into four groups (three treatments and one control group) and each group had 06 anestrus buffaloes. Group I, II and III were treated with CIDR plus Ovsynch, CIDR plus Cosynch and eCG plus Cosynch protocols, respectively, while the control group (Group IV) animals were not given any treatment. The results revealed that the occurrence of postpartum anestrus in buffaloes was 69.10%. The percentage of postpartum buffaloes with 60–90 days, 90–150 days and more than 150 days postpartum were recorded to be 25.30, 45.78 and 28.91%, respectively. Irrespective of treatment groups, the overall estrus intensity ranged from 58–92 with a mean estrus intensity score of 70.58±2.89. Estrus intensity scoring is a good tool to describe the intensity of estrus which has a positive relationship with fertility.
