<![CDATA[Information of performance reproduction crossed result of cow in ranch was immeasurable enough because condition of its different conservancy. This research aimed to know difference of reproduction performances of Simmental Crossed Cow (PSM) result of Artificial Insemination (AI) looked after by farmer of breeder of Group Farmer Livestock member (KTT) and non member of KTT in District of Sukoharjo.

Calving interval differ reality (KTT 392.28 ± 77.27 day, non KTT 416.02 ± 64.63 day); non return rate differ reality (KTT 87.72 ± 11%; non KTT 79.53 ± 18%); service per conception do not differ reality (KTT 1.12 ± 0.32; non KTT 1.19 ± 0.40.
