Studies on haemato-biochemical profile of adult Jersey crossbred heifers during anestrus and non-hormonal induction of estrus

摘要

In order to assess the haemato-biochemical profiles of adult Jersey crossbred heifers during anestrus and induced estrus condition, 12 adult heifers were selected for experimental studies. The age of the heifers were in between 2.5 - 3 years. The bodyweights were ranged between 185.5 - 252 kg. Selected animals were subjected to gynaecological examination per rectum and confirmed they were in anestrus condition. Heifers were maintained under standard managerial condition and feeding and they were treated with anthelmintic, mineral mixture, vitamin A injections and non-hormonal herbal preparation (Sajani,Tai Sarabhai Zydus) for induction of heat. Blood samples were collected during anestrus and within 12 h after onset of heat symptoms (estrus). Eightanimals exhibited estrus signs among treated animals. The results revealed that the total erythrocyte count, haemoglobin, packed cell volume, serum glucose, total serum protein, serum globulin, serum aspertate transaminase, serum alanine transaminase and serum alkaline phosphatase were significantly (P < 0.01) higher during estrus than in anestrus condition. The lymphocyte count was also significantly (P < 0.05) higher during estrus than anestrus condition. No significant differences were observed in mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, eosinophil count, basophil count, monocyte count, serum albumin and serum total cholesterol content between estrus and anestrus condition. Based on the observations, it may be concluded that good managerial practice along with treatment with non-hormonal herbal preparation improved physiological status of the anestrus animal.
