The use of engineered nanomaterials has increased as a result of their positive impact on many sectors of the economy, including agriculture. Silver nanoparticles (AgNPs) are now used to enhance seed germination, plant growth, and photosynthetic quantum efficiency and as antimicrobial agents to control plant diseases. In this study, we examined the effect of AgNP dosage on the seed germination ...

The objective of this study was to examine the effects of dietary forage level and fat supplementation on the chemical composition of mixed ruminal bacteria (MRB). Six ruminally cannulated beef steers (354 kg +/- 18) were given ad libitum access to six diets (13.2% CP; DM basis) that were offered twice daily in a 6 x 6 Latin square design. Treatments were arranged as a 2 x 3 factorial with two ...

Corn silage is a palatable high energy, low protein forage that is used in most dairy rations across the US. The usage of corn silage has grown over the last decade. Seed companies have focused breeding activities on corn silage hybrids resulting in corn silage hybrid differences that rival other species in nutritional differences. When making decisions about the quality of corn silage, dairy p...
