Whole-plant corn was harvested at early dent, quarter milkline, two-thirds milkline, and black layer stages to evaluate the effects of maturity on intake, digestion, and milk production when corn was fed as silage in the diet. Twenty multiparous Holstein cows were used in a replicated experiment with a 4 x 4 Latin square design with 28-d periods. Diets containing 50% forage (67% corn silage and...
approved: Redacted for Privacy Dr. James 15 Oldfield Chemical and biological evaluations were conducted to provide chemical composition and digestibility information, in addition to yield data, for silage corn varieties produced on poorly drained Dayton soil series. Each variety was subjected to a Kjeldahl nitrogen, acid detergent fiber, acid detergent lignin, cell wall, and residual ash test. ...
This study was conducted to investigate the effect of formic and sulphuric acids on chemical composition, dry matter (DM) and crude protein (CP) degradability of alfalfa silage and its effect on early lactating Holstein cow as three trials. In the first trial, chopped alfalfa (22 and 33% DM) was ensiled with three levels of formic acid (0.0, 15 and 20 ml/kg DM) and two levels of sulphuric acid ...

Twenty-four multiparous Holstein-Friesian dairy cows were used in a replicated 3×3 Latin square changeover design experiment to test the effects of changing from corn (Zea mays) silage to red clover (Trifolium pratense) silage in graded proportions on feed intakes, milk production, and whole-body N and P partitioning. Three dietary treatments with ad libitum access to 1 of 3 forage mixtures plu...
Effect of Rumex Sc on Ruminal Fermentation, Blood Metabolites and Performance of Lactating Dairy Cow
This study investigated the effect of Rumex Sc (commercial product which includes of Saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. Animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). Additionally, Rumex Sc was included in the experimental d...
Although Brahman crosses constitute a large portion of US beef cattle, little information is available on their response to diverse feed resources compared with Bos taurus steers. Thus, the objectives were to evaluate genotype and diet effects on steer performance during the growing period and subsequent response to a high grain diet during the finishing period. Fifty-one steers [0 (15), 1/4 (2...
Three corn hybrids harvested as whole-plant silage were evaluated in three separate feeding trials with lactating dairy cows. In trial 1, 24 multiparous Holstein cows were used in a replicated 4 x 4 Latin square with 28-d periods. Treatments were conventional (Pioneer 3563) and leafy (Mycogen TMF 106) corn silage hybrids, each planted at low (59,000 plants/ha) and high (79,000 plants/ha) plant ...
Beef knuckles (n = 160) were obtained from source-verified cattle finished on 30% wet distillers grains plus solubles enriched with varying levels of alfalfa hay (4 or 8%), corn silage (6 or 12%), or corn stalks (3 or 6%) based on NDF. Proximate analysis, pH, oxidation-reduction potential, fatty acid composition, and sensory analysis were conducted on the rectus femoris muscle to determine if r...
Two experiments using six rumen-fistulated Holstein steers in 3 X 3 Latin square designs were conducted to test the effects of urea addition to corn silage, and grain addition to haylage, on feed intake, digestibility of nutrients and rumen fermentation of complete diets fed once daily. Addition of .34 and .68% urea to corn silage increased dietary crude protein from 8.1 to 11.3 and 13.3%, and ...
