This study, consisting of three experiments, was conducted to determine the effects of feeding feather meal (FM), feather meal digest(FMD), L-cystine and methionine hydroxyl analogue (MHA) on taurine content of milk and milk production of Holstein dairy cows. In experiment 1, FM or FMD was supplemented at 0, 1, 3 and 5% of dry matter intake(DMI), respectively. Taurine concentration of 3% FM and 5% FMD treatment were increased by 14% and 22%, respectively. The 5% FM treatment had a negative effect on milk yield and FM and FMD treatments had no significant or consistent effects on milk fat, protein, lactose, milk urea nitrogen (MUN) and somatic cell count (SCC).
