Suwarno, Wittenberg, K. M., Ingalls, J. R. and McCaughey, W. P. 2000. Performance of lactating dairy cows fed macerated forage conserved as silage and hay. Can. J. Anim. Sci. 80: 123–129. The effect of forage maceration at harvest on silage characteristics and its effect on lactation performance of Holstein cows were determined. Either a roller conditioner or a prototype forage macerator manufa...

A series of in vitro fermentation experiments was performed to assess the effects of 4 feed enzyme products (FE) that varied in enzymatic activities on the degradation of alfalfa hay and corn silage. The FE contained a range of endoglucanase, exoglucanase, xylanase, and protease activities, and a range of dose rates (DR) was used. The objective of the study was to identify effective formulation...

In recent years, the use of microbial inoculants has been increasing in Brazil, although the results have been conflicting. This study was conducted to evaluate the effects of adding a by-product from amino acid production or biological inoculants on fermentative characteristics, chemical composition and aerobic stability of corn silage. The treatments were: Control (control silage without addi...

This study evaluated the effect of feeding silage to pigs on nitrogen (N) utilization and ammonia (NH3) volatilization. In total, 128 Yorkshire × Hampshire (30–110 kg) were fed commercial feed (Control) or mixed with dried, milled in pelleted form (Pellet-S), fresh, chopped (Silage-Ch) intensively treated (Silage-Pr). Silage replaced 20% crude protein (g/kg). Diet affected daily N excretion, wh...

The effect feeding olive-pulp silage (OPS) for 120 days on several blood attributes was studied using 16 rams allotted to two diets consisting of 70% corn silage or 70% OPS. Olive-pulp silage feeding resulted in lower serum total protein, alanine aminotransferase, calcium and phosphorus levels and higher glucose concentration compared to the corn silage diet. Body weight and other blood attribu...

Grain sorghum silage tannin content effect was evaluated on milk production and chemical composition of Argentinean Holstein bred cows, and it are described dry matter (DM) and crude protein (CP) in situ digestion parameters and effective degradability. The base diet was constituted by alfalfa pasture, maize silage, and a protein – mineral supplement, differing in three treatments based on high...

One of the most common problems faced by hay or silage producers is how to manage production schedules around unfavorable weather. Inevitably, some wilting forage crops are damaged by rainfall each year, and producers often inquire about the effects of rain damage, and what impact this may have on forage quality, silage fermentation, and animal performance. Actually, the problem is more complex...

This study examined the effects of bacterial inoculants on chemical composition and fermentation indices of barley silage. Barley forage (Youngyang) was harvested at 24% dry matter (DM) and wilted to 47.9% DM. The wilted barley forage was chopped to 3-5 cm length and applied with no inoculant (CON), L. plantarum (1×10(10) cfu/g, LP) or Effective Microorganisms (0.5×10(9) cfu/g, EM). Then the fo...

An experiment with growing lambs was designed to test the hypothesis that alterations in blood acid-base status would influence intake of corn silage. Six wethers (29 kg) were fed a diet of corn silage (36% DM, 8% CP) supplemented with 1.25% urea and .2% sulfur. At feeding time, sodium bicarbonate (NaHCO3) and sodium sesquicarbonate (NaSC) were added to the silage at levels of 0, 2% or 4% of di...

Corn was inoculated with Lactobacillus plantarum and Propionibacterium freudenreichii subsp. shermanii either independently or as a mixture at ensiling, in order to determine the effect of bacterial additives on corn silage quality. Grain corn was harvested at 32-37% of dry matter and ensiled in a 4 L laboratory silo. Forage was treated as follows: bacterial types: B0 (without bacteria-control)...
