Effects of milk replacer program on nutrient intake, growth
The aims of this study were to determine if feeding frequency (FF) of milk replacer (MR; meals/d) alters starter intake, growth and efficiency of growth in nursery calves fed a conventional or accelerated MR.

Effects of feeding brown midrib corn silage with alfalfa hay
This experiment was conducted to test a hypothesis that lactating dairy cows fed 35 percent brown midrib corn silage and 25 percent alfalfa hay would consume more DM around peak lactation compared with those fed conventional corn silage, resulting in longer peak milk production.
