Deteksi Gangguan Reproduksi Sapi Bali Melalui Teknik Radioimmunoassay (RIA) dan Analisis Tatalaksana Pemeliharaan

Abstract

This study aims to detect the interference of reproduction of Bali cow which gave birth for more than 90 days and they do not appeal oestrus yet and although having been treated in Artificial Insemination (Al) for more than twice, the pregnant still did not happen yet (Service/Conception > 2), with age female cow more than two and a half years not yet appears oestrus. This research applies Radioimmunoassay techniques (RIA) by giving a hormone progesteron profille and also supporfed by maintenance management aspect analysis. This study is a research survey, using 15 cattles of Bali cow who have experienced in reproductIve interference. Bali cows are grouped bason gave birth for more than 90 days and they do not appeal oestrus yet, although having been treated in Arficial Insemination (Al) for more than twice, the pregnant still did not happen yet (S/C more than two) and Bali cow age more than 2,5 years not yet appears oestrus. In each group there are 5 Bali cows. They are measured in terms of the condition of mother and taken blood samples to measure hormone progesteron analysis. Interviews were also conducted directly to the owners of the cattle related to the maintenance of management as the researoh object so that it would support the data analysis as the results of progesteron hormones, especially in the data interpretation. This research was conducted in several groups of the cattle work group which located in Tanah Laut Regency. The work group consists of Tri Jaya, Mekar Jaya and the centre of Training and Dissemination of Integrated Technology of Agriculture and Animal Husbandry of of the Faculty Of Agriculture of Unlam in Sei Riam and also some farmers in Banjarbaru. The preparation of blood sample for being analysed using RIA methed at the Laboratory of the Faculty of Agriculture. After that the result of RIA is conducted at the of RIA is conducted at the Radioisotop Laboratory, Division of Energy and Isotope Researoh Center Activities of Unhas. The results of research shows that Bali cows which possess more than 90 days of a torrid post-partum mainly caused by the unintensive detection of sex appeal. This may result of the condition of parent become decrease, therefore the post partum does not show up. The Bali cows have more than the two S/C, it caused mainly by oestrus detection not intensive, so that execution time AI/ marriage imprecise. Bali cows late appears oestrus mainly caused by oestrus detection not intensive and the consequences of feed given which deficit of certain nutrient substance or have less a certain quality.
