In European countries, silage-free feeding is an ancient tradition and has a particularly positive reputation among consumers. the present study, we compared grass-based forages from same plot conserved as hay or silage fed fresh either on pasture indoors, evaluated differences in sensory properties of milk uncooked pressed cheese. All herbage first cut grassland dominated by perennial ryegrass...

Dry matter intake (DMI) is a primary determinant of milk production in grazing dairy cows and an ability to measure the DMI individual would allow herd managers formulate supplementary rations that consider amount nutrients ingested from grass. The 2 related aims this experiment were define mean number swallowed boli mass Holstein-Friesian cattle offered variety forages commonly fed industry so...

AND INTRODUCTION In the Western United States poisonous plants are estimated to cost the animal industry more than 200 million dollars annually. The majority of these losses are attributed to livestock grazing on rangelands. Little has been done to determine the costs of livestock poisoned by contaminated feeds which are probably more frequent and costly. Grazing livestock generally avoid eatin...

Both the anti-nutritional and beneficial effects of secondary compounds in a range of temperate and tropical forages have been reviewed. Major secondary compounds in temperate and tropical forage plants occur in the phenolic fraction and include condensed and hydrolysable tannins, phenolic monomers and lignin. Condensed tannins (CT) bind to plant protein by pH-reversible hydrogen bonding. In te...

Effects of plant-bound condensed tannin (CT)-containing sainfoin vs. CT-free alfalfa (or low-CT alfalfa-sainfoin mixture), plant stage of maturity, and their interaction on enteric methane (CH4) emissions, diet digestibility, and N excretion were studied, using 8 ruminally cannulated beef heifers in 2 sequential short-term experiments (Exp. 1 and 2). In Exp. 1, first growth legumes were harvest...

An experiment was conducted to determine animal performance and gain/ha of beef steers (mean initial wt.: 241 kg) grazing a conventional sorghum x sudan hybrid (C) versus its near isogenic brown midrib (BMR) variety. The experiment was conducted during the summers of 1999 and 2000 in the Texas Panhandle. During both summers 8 pasture plots (2.2 ha) were blocked by location and randomly assigned...

A field trial was conducted on 5 farms to determine the effect of feeding distillers dried grains (DDGS) on milk production in the southern dairy region of Chile. The trial was repeated on each farm during winter (July and August; primarily silage-based rations) and spring (November and December; pasture-based rations). Only for one farm could the treatments be applied concurrently by feeding d...

1. Twenty Friesian steers (225 kg live weight) were fed on mid- (M) (June-July) and late- (L) (August-September) season crops of either fresh perennial ryegrass (Lolium perenne cv. Melle) (G) or white clover (Trifolium repens cv. Blanca) (C). Each of the forage diets was offered at three restricted planes of nutrition above maintenance to compare the effect of forage species on the efficiency o...

The objective of this study was to compare the application of different in vitro and in situ methods in empirical and mechanistic predictions of in vivo OM digestibility (OMD) and their associations to near-infrared reflectance spectroscopy spectra for a variety of forages. Apparent in vivo OMD of silages made from alfalfa (n = 2), corn (n = 9), corn stover (n = 2), grass (n = 11), whole crops ...
