Abstract: In this study, the effects of Protected Fat (PF) supplementation on the performance and some milk parameters were investigated on dairy goats. The experiment began after completion of the parturitions and lasted for 8 weeks. The animals were individually fed with an additional 100 g PF a day in the supplementary group. The data on Body Weight (BW), Concentrate Feed Intake (CFI), Dry Matter (CDM), Crude Protein (CCP), Metobalizable Energy (CME) intake in concentrate feed was observed every week. Moreover, Milk Yield (MY), Milk Dry Matter (MDM), Milk Fat (MF), Milk Ash (MA), Milk Density (MDEN) and Milk pH (MpH) was observed every 2 weeks during 8 weeks period. The results indicated that there was statistically significant differences in BW between weeks (p<0.01) although, a statically significant interaction between weeks and groups were found in terms of CFI (p<0.01). The BW increased from the beginning of experiment to the end of experiment. Although, CDM and CCP in PF group decreased, there was an increase in CME. Regarding MY, PF group was not significantly differed (p>0.05) from the NPF group. The results showed that the interaction between groups and weeks was statistically significant in terms of MF (p<0.05). While, the differences in MDM between both weeks and groups were statistically significant (p<0.05), there was significant divergence only between weeks regarding MA, MpH and MDEN (p<0.01). The findings of this study clarified that PF group had the higher MDM and MF.
