Abstract
MUN is high due to high protein content in feed, Thehigh level of MUN can affect hormonal systems including growth hormone IGF-1 and reduce pregnancy rates. The aim of this study is to determine MUN as an indicator of feed evaluation and see the corelation between MUN and IGF-1 levels and pregnancy rates. The cows according to the criteria were sampled to determine the levels of MUN and IGF-1 then processed with the application curve ekspert 1.4 and SPSS 20. Value r = 0.75 between MUN and IGF-1 stated that there was a strong correlation between the two. There were significant differences between MUN and pregnancy rates (P <0.05). High and low levels of MUN will affect pregnancy rates. All sample of MUN with levels of 17-28.5 mg/dl did not have pregnancy and MUN with levels of > 12 mg/dl was obtained in five out of eight pregnant.
