A novel method of harvesting whole-plant corn silage, shredlage, may increase kernel processing and physically effective fiber. Improved fiber effectiveness may be especially advantageous when feeding brown midrib (BMR) corn hybrids, which have reduced lignin content. The objective of this study was to determine the effect of feeding TMR containing BMR corn shredlage (SHRD) compared with BMR co...
Ten ruminally cannulated lactating Holstein cows that were part of a larger trial studying the effects of feeding different proteins on milk production were used in a replicated 5 x 5 Latin square to quantify flows of microbial and rumen-undegradable protein (RUP) in omasal digesta. Cows were fed total mixed rations containing (dry matter basis) 44% corn silage, 22% alfalfa silage, 2% urea, and...
In a replicated 4 x 4 Latin square design with 4-wk periods, we used 12 multiparous Holstein cows averaging 83 d postpartum to compare corn distillers grains (CDG) versus a blend (BLEND) of other protein sources with CDG (fish meal and soybean meal), and to determine the effectiveness of ruminally protected lysine and methionine (RPLM) in improving the utilization of CDG as a protein supplement...
Two feeding trials evaluated several byproducts from commercial amino acid fermentations as N supplements for lactating cows. Trial 1 was a replicated 5 x 5 Latin square that used 2-wk periods and 25 Holstein cows (five with ruminal cannulae) fed diets containing [dry matter (DM) basis] 28% alfalfa silage, 31% corn silage, 28% high moisture ear corn plus 4 percentage units of crude protein (CP)...
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...
Physically effective fiber is needed by dairy cattle to prevent ruminal acidosis. This study aimed to examine the effects of different sources of physically effective fiber on the populations of fibrolytic bacteria and methanogens. Five ruminally cannulated Holstein cows were each fed five diets differing in physically effective fiber sources over 15 weeks (21 days/period) in a Latin Square des...
The study was conducted to screen high 1,2-propanediol produced by Lactobacillus buchneri strains, isolated from baled silages stored for 1 or 2 years, and evaluate their effects on fermentation quality aerobic stability of whole-plant corn silage. In total, 31 L. strains were alfalfa, oat silages. Based growth performance acetic acid production, two 9-2 10-1, alfalfa silage, further assessed i...
The aim of this study was to evaluate the effects of tannic acid (TA) and pistachio by-product tannin extract (PBE) on N utilization and efficiency of microbial nitrogen synthesis (EMNS) in Saanen dairy goats. The experimental design was a change over design with three treatments and three periods using six mid lactation multiparous dairy goats. Tannic acid solution and PBE were added to fresh ...
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...
The purpose of this study was to investigate the effects of supplementation of alfalfa silage with Lactobacillus buchneri additive, orange pulp and molasses on dry matter, crude protein and organic matter degradability by nylon bags. The treatments included: alfalfa silage (control treatment), alfalfa silage processed with bacterial additive, 3×108 cfu/g, alfalfa and orange pulp silage, alfalfa...
