摘要

Title of the paper: The introduction of automatic single animal recognition possible with a simultaneous weighing of the animalscan help during the practice transfer of results from growth investigations. Differing live weights at the end offattening represent a problem, that only let consider and solve with growth investigations. In this connectionwere realized already 1989 investigations (1st communication). The results should be matched in thiscommunication with that newer date. In the investigation of 2005 in the farms IIa/ IIb, masculine and femininepigs were weighed six times. These data records were provided separated to a estimation procedure fordetermination the parameters (growth function of Lehman) for each animal. Among other things, the values ofthe theoretical possible end weight could be determined by means of the mentioned function from the weighingdata. According to these values became ascendingly sorted and subsequent the data records of the animals innine groups divide. Consequently group 1 contained those animals with small possible end weights and group 9for example with the highest ones. The following statements can be hit: In the group arrangement of the ninegroups can be confirmed in direction the statement in year 1989, that a low growth intenseness go along with onehigh possible end weight and a high growth intenseness with a small one, that however this state of affairs cannot be supported in single animal arrangement in this consequence. Further, the statement can be confirmed thata high growth intenseness is be compared with a more rapid cycling the growth relevant dates and/or a low onewith a slower one. The respective statements can not be confirmed with the single animal arrangements of years1989 and 2005 from the group arrangements, that a high growth intenseness always agree with an early attainingof the maximum of daily increase in live weight and/or a low with a late attaining.
