Alfalfa is the most planted perennial legume in world due to its high nutritive value, protein content, productivity, and digestibility addition vitamin mineral content. It also one of hardest plants ensile owing low reducible sugar dry matter (DM) contents buffering capacity. In this study, effects inoculation with Lactobacillus bifermentans which homofermentative brevis heterofermentative on ...

abstract in this study 36 holstein bulls (initial bw of 345±61 kg) were randomly assigned to 6 dietary treatments, following a 3×2 factorial arrangement, with 3 concentrate level of fish oil (0, 1 and 2.1% of dm) and 2 levels of alfalfa hay versus corn silage (10 and 20 % of alfalfa hay forage) to investigate the effects of fish oil supplementation and ratio of alfalfa hay and corn silage in di...

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...

Effects of corn silage crop processing and chop length on intake, digestion, and milk production were evaluated. Corn silage treatments were harvested at one-half milkline stage of maturity (65% whole-plant moisture content) and at 0.95-cm theoretical length of cut without processing (control) or 0.95-, 1.45-, or 1.90-cm theoretical length of cut with processing at a 1-mm roll clearance. Twenty...

The objective of this study was to compare utilization of red clover (Trifolium pratense L.) and alfalfa (Medicago sativa L.) by lactating dairy cows. Red clover and alfalfa were harvested and conserved as silage at two maturities in 2 consecutive yr. Each year, diets containing experimental forages and supplemental grain were fed to 16 multiparous Holstein cows in early lactation in a replicat...

Pediococcus species isolated from forage crops were characterized, and their application to silage preparation was studied. Most isolates were distributed on forage crops at low frequency. These isolates could be divided into three (A, B, and C) groups by their sugar fermentation patterns. Strains LA 3, LA 35, and LS 5 are representative isolates from groups A, B, and C, respectively. Strains L...

Introduction The large proportion of CP in alfalfa silage (AS) that is present as NPN substantially reduces the efficiency of protein utilization by lactating dairy cows (Nagel and Broderick, 1992). Red clover silage (RCS) typically has a much lower content of NPN than AS (Albrecht and Muck, 1991). In a previous feeding study (Broderick and Sterrenburg, 1996 USDFRC Res. Sum.), we found that DMI...

Seventy-two pregnant ewes were al lot ted to three ration t reatment groups: 1) Control: corn silage and alfalfa pellets; 2) Tallow: corn silage, alfalfa pellets and protected tallow; 3) Polyunsaturated (P/S): corn silage and protected soybean and sunflower seeds. Diet influenced plasma glucose and linoleic acid content of esterified, but not of non-esterified, fat ty acids in ewe plasma. Propo...

Several feed preservation methods can ensure lower mycotoxin contamination levels enter the food life cycle, and a relatively common wet method of forage plant materials is fermentation. This study aimed to characterize microbiological state fermented silages haylages (corn, alfalfa, rye, triticale), their main microbiota, isolation bacteria with resistance. Bacteria that remain viable througho...
