- Abstract
The aim of the study was to examine effects of pre-partum feeding on post-partum intake, production and energy balance in cows. Two weeks pre-partum (w-2, w-1) different amounts of one concentrate was fed to group Low (L) and High (H) while the same amount of another concentrate was fed during the first four weeks post-partum (w1, w2, w3, w4). Silage was available ad-libitum during the experimental period. Dry matter intake was higher in group H (P.0.05) except for w1. Energy corrected milk (ECM) yield did not differ between groups; however, in contrast to group L there was a clear increase in ECM yield from w1 to w4 in group H (P<0.0001). Milk fat yield tended to be higher in group H on w3 (P=0.06) and was higher on w4 (P=0.05), milk lactose yield was higher in group H on w4 (P=0.04); protein yield did not differ between the groups. Energy balance was more positive in group H pre-partum (P<0.0001) and did not differ post-partum. Obtained results indicate that increasing feeding level pre-partum could improve post-partum intake and production performance at the same time having little influence on energy balance.
