    abstract = {This study was done to evaluate the effects of restricting Total Mixed Ration (TMR) and supplying <I>Eragrostis curvula</I> and <I>Medicago sativa </I>hay mixture adlib on lactation performance of mid-lactation multiparous Holstein cows. Twenty Holstein cows, averaging 598&plusmn;73 kg body weight and 100 days in milk were assigned to either a 100% TMR diet (control) or a 75% TMR-restricted diet. Cows on the 75% TMR-restricted diet had adlib access to <I>E. curvula</I> and <I>M. sativa</I> hay mixture (1:1). The experiment included 2 weeks adaptation period and 4 weeks sampling period. Cows were milked twice daily. Total Dry Matter Intake (DMI), DMI as BW%, daily CP intake and intake of net energy for lactation were higher (p&lt;0.05) for cows on the 100% TMR than for cows on the 75% TMR. Cows in 75% TMR consumed 12.5% less total DM and 14.2% less kg DM as of BW% than cows in 100% TMR. Intake of NDF was not affected (p&gt;0.05) by treatment. Milk yield, milk fat% and yield (kg day<SUP>-1</SUP>) did not differ between treatments and averaged 29.2 kg day<SUP>-1</SUP>, 3.70% and 1.08 kg, respectively. Feed efficiency ranged from 1.22-1.37 and tended to be higher (p&lt;0.10) with 75% TMR diet. Efficiency of nitrogen and phosphorous utilisation was not affected (p&gt;0.05) by treatments. Results suggest that TMR restriction to 75% during mid-lactation does not negatively impact milk production.}
