Quantitative prediction of the date of delivery of production animals
The invention relates to a method for the quantitative prediction of the date of birth of livestock by acquiring empirical activity data, activity data being contactlessly acquired by means of acoustic, light, ultrasonic or radar sensors. Said sensors are mounted above or laterally of individually kept animals and have a field of vision that is limited to the box or pen. Parameters of a growing restlessness of pregnant livestock prior to the onset of birth are detected, automatically recorded and standardized individually for each animal. The measured and standardized animal-individual activity curve is used for a numerical approximation of the date of birth with the aid of an activity curve which is characteristic of every animal species, breed, age and weight and other previously known animal parameters.
An increasingly intensified livestock of Production animals demands more from the inspection and care for each animal. Automation and standardization of livestock husbandry will be implemented to realize these demands. A particularly intensive care period is the birth and initial care of the newborn animals.
In order to ensure timely delivery the staff observes the animals during the critical period before the birth. At the same time an attempt is made to synchronize the time of birth in a group of animals via ad-ministration of hormones.
This method of hormonal synchronization and hormonal induction of labour causes environmental pollution, which is comparable to the impact of human contraceptives.
Process for individual prognosis of the actual birth date can automate the prenatal monitoring. The timely detection of deviating birth dates in young animals is possible, this reduces the workload of obstetric care. This allows a reduction of the given hormones.
Even today it is possible to provide quantitative information about the beginning of birth by using simple sensors. The invention supplements warnings with information on the probable beginning of the birth. These quantitative predictions are based on the indirect measurement of prenatal anxiety in animals. Such agitation can be expressed in vocalization, locomotion and interaction. This can be measured by using acoustic, light, ultrasonic or radar sensors. The prediction itself is based on empirically proven assumptions about the natural history of the measured parameters during the prenatal period. Parameters such as agerelated differences are taken into account.
- Timely initiation of measures for obstetrics and primary care of the newborns
- Increased chance of survival of the newborns
- Reduction of hormone use in animal breeding
- Automation of downstream processes such as climate control or monitoring of the pups
