A Method for Forecasting the Dates of Mass Calving and Some Characteristics of the Rut and Calving in the Kalmyk Population of Saiga (Saiga tatarica L.)

A Method for Forecasting the Dates of Mass Calving and Some Characteristics of the Rut and... A method for forecasting the dates of calving in the saiga population on the basis of average fetal body weight is proposed. The method is based on the relationship between the number of days before calving and the average weight of fetuses, which obviates the necessity of determining fetal age and exact gestation period in this species. The average length of gestation, the dates of the rut in the years studied, and the age of females that have mated immediately upon the onset of the rut and before its cessation have been determined. It is shown that the duration of mass calving depends on the proportion of mature males in the population. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals
