Popis: | The indigenous Madura cattle semen production and quality were evaluated. Total of 2275 semen collection records from 11 bulls were analyzed to evaluate the genetic potency of semen productions. The genetic evaluation was described as an estimation of bull semen volume, sperm concentration and sperm individual motility. Data were analyzed by HGLM-REML with environmental factors of age, seasons, interval of semen collections and frequency of ejaculations as fixed effect. The result showed that the age and the ejaculation frequency affected to all variables; an interval of semen collections affected to both semen volume and sperm concentrations; and seasons only affected to sperm concentrations. Repeatability estimate of semen volume, sperm concentration and sperm individual motility were 0.376, 0.445 and 0.567 respectively. It can be concluded that the quality of ejaculate was less affected by environmental factors, supported by the good adaptation of indigenous Madura cattle under the local climatic conditions and management in the artificial insemination station. |
