This study aims to determine the effect of partial (50% and 75%) complete (100%) replacement barley corn silage with whole plant faba bean on milk production, feed intake efficiency, digestibility, rumen fermentation characteristics high producing cows. A repeated 4 × Latin square (early lactating cows: four cannulated non-cannulated) design was used. The used for treatments were different: con...

The objective of this study is to investigate individual animal variation of bovine fecal microbiota including as affected by diets. Fecal samples were collected from 426 cattle fed 1 of 3 diets typically fed to feedlot cattle: 1) 143 steers fed finishing diet (83% dry-rolled corn, 13% corn silage, and 4% supplement), 2) 147 steers fed late growing diet (66% dry-rolled corn, 26% corn silage, an...

Interseeding silage corn into an alfalfa stand following its spring harvests to produce mixed would feasibly break the restriction of production during a hot-rainy summer. In this 2-yr experiment, alfalfa–silage intercropping system (AC) with nitrogen (N) fertilization rates 0, 60, 120, and 180 kg N ha?1 plant densities 30,000, 45,000, 60,000 plants was compared monocultured (CK) managed using ...

Understanding of the bovine fecal microbiome could contribute to solving issues regarding animal production, cattle health and food safety. The objective of this study was to examine the influence of diet on the fecal microbiome in feedlot cattle. The next-generation pyrosequencing technology was used to investigate fecal microbiomes of 426 cattle fed one of 3 diets: finishing diet (83% dry-rol...

The objective of this study was to determine if the effects of inoculation with Lactobacillus buchneri 40788 were detectable when applied to whole-plant corn stored in farm silos. Corn silage was randomly sampled from farms in Wisconsin, Minnesota, and Pennsylvania, and was untreated (n = 15) or treated with an inoculant (n = 16) containing L. buchneri 40788 alone or this organism combined with...

The objective of this study was to investigate the effects of tallow and choice white grease (CWG) fed at 0, 2, and 4% of the diet dry matter (DM) on rumen fermentation and performance of dairy cows when corn silage is the sole forage source. Fifteen midlactation Holstein cows were used in a replicated 5 x 5 Latin square design with 21-d periods. Treatments were 0% fat (control), 2% tallow, 2% ...

The aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. Alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). During the preparation of experimental micro-silages, the chopped forage was treated with a microbia...
