Abstract

This study was conducted to evaluate the effects of feeding rye silage and feed restriction on both growth and reproductive performances in replacing gilts. Twenty four replacing gilts (Landrace×Yorkshire, 67.63±1.17kg initial BW) were used in 49 d growth assay. Dietary treatments were included 1) CON(basal diet), 2) S15(15% feed restriction + ad libitum rye silage) and 3) S30(30% feed restriction + ad libitum rye silage). In growth performance, average daily gain and average daily feed intake were the highest in CON among treatments(P<0.05). Average daily silage intake was not significantly different between S15 and S30 treatments(P>0.05). Feed conversion ratio was the lowest in CON among treatments(P<0.05). Average silage intake of S15 and S30 treatments was increased as time goes by(P<0.05). While all gilts of S15 and S30 treatments became pregnant, one gilt of CON became pregnant. Also, first estrus and mating were occured earlier in S15 and S30 than those of CON. In conclusion, 15% feed restriction and feeding rye silage reduced growth performance, reached earlier to first estrus and increased pregnancy rate in replacing gilts.
