The objective was to compare the effectiveness of combining Lactobacillus buchneri 40788 with three lactic acid bacteria on the fermentation, aerobic stability and nutritive value of corn silage. Freshly chopped whole plant corn was untreated or treated with L. buchneri 40788 paired with Lactobacillus plantarum, Pediococcus acidilactici, or Pediococcus pentosaceus. L. buchneriwas added to achie...

One hundred and twenty steers (512  37 lb) were stratified by weight and assigned randomly to incremental levels of DDGS treatments. Steers were limit fed a 47.5% alfalfa, 47.5% WCGF 5% supplement diet for five days at the beginning and end of the trial and weighed for three consecutive days to minimize variation due to gut fill. Treatments included 1.5, 2.5, 3.5, 4.5, 5.5, and 6.5 lb DDGS/ he...

Reductive acetogenesis by homoacetogens represents an alternative pathway to methanogenesis to remove metabolic hydrogen during rumen fermentation. In this study, we investigated the occurrence of homoacetogen in the rumens of pasture-fed roe deer (Capreolus pygargus) and sika deer (Cervus nippon) fed either oak-leaf-based (tannin-rich, 100 mg/kg dried matter), corn-stover-based, or corn-silage...

Corn silage represents a mixture of highly digestible, energy-dense grain and a poor quality forage (stover). The value of altering the grain to stover ratio through agronomic and harvesting strategies has been recognized for some time, however many of these practices have been applied to hybrids selected primarily for grain yield and adapted for harvest as silage. Although the feeding value of...

The objective of this experiment was to evaluate effects of reducing corn silage particle size on eating behavior, chewing activity, and rumen fermentation in lactating dairy cows. Four cannulated, multiparous cows averaging 110 +/- 4 d in milk and weighing 675 +/- 70 kg were randomly assigned to a 4 x 4 Latin square. During each of four 14-d periods, animals were offered one of four diets that...

This paper presents a number of applied management practices, based on data and research, necessary for dairies in the western United States to produce, store and fed high quality corn silage. These management practices include hybrid selection, growing a quality crop, proper harvest timing, chopping, packing, inoculating and feed out of the stored corn silage.

The objective of this study was to determine if the length of chop of processed corn silage influences the impact of supplemental fat on rumen fermentation and performance of dairy cows. We hypothesized that increasing forage particle length may alleviate the interference of fat on rumen fermentation. Sixteen Holstein cows averaging 120 d in milk were used in a replicated 4 x 4 Latin square des...

Eight ruminally cannulated Holstein cows that were part of a larger lactation trial were blocked by days in milk and randomly assigned to replicated 4 x 4 Latin squares to quantify effects of nonprotein N (NPN) content of alfalfa silage (AS) and red clover silage (RCS) on omasal nutrient flows. Diets, fed as total mixed rations, contained 50% dry matter from control AS (CAS), ammonium tetraform...

The main objective of this study was to obtain scientifically sound data on the bioenergy potential of dairy manures from cows fed different levels of corn dried distillers grains with solubles (DDGS). Three diets differing in corn DDGS content were formulated: 0% corn DDGS (DDGS0; control diet), 10% corn DDGS (DDGS10) and 30% corn DDGS (DDGS30). Bioenergy production was determined in psychroph...

Two experiments were conducted to determine the effects of salinomycin and lasalocid on metabolism and growth of growing steers. In Exp. 1, 80 Angus steers (228 kg) were assigned to the following treatments: 1) control, 2) 50 mg salinomycin.hd-1.d-1, 3) 100 mg salinomycin.hd-1.d-1 and 4) 250 mg lasalocid.hd-1.d-1. Steers were fed corn silage once daily with allotments based on the amount of sil...
