TL;DR: In this article, the effect of various levels and types of concentrate supplementation of roughage-based diets on dry matter degradation, rumen cellulolysis and rumen pH, as well as changes in the rumen microflora and in the proportion of volatile fatty acids (VFA) produced were investigated.

TL;DR: In this article, it was shown that the reduction of the rumen pH (to 6.0-6.1) in sheep given roughage led to the inhibition of cellulolysis and partial destruction and washout of rumen microflora.

TL;DR: In the first two experiments, fixed amounts of barley were offered, with hay freely available, while in the second, fixed ratios of hay and barley are offered ad libitum as mentioned in this paper, and it was concluded that negative associative effects could be largely avoided if the rumen pH was maintained above the level inhibitory to cellulolysis.

TL;DR: In this article, the effect of NH3 on the pattern of fermentation was studied over a period of 42 days, and the NH3 resulted in an initial decrease in the population of yeasts and moulds, and Lactobacillus organisms; a reduction (47.9%) in weight loss; and a reduction(46.4%) in the loss of water-soluble carbohydrates (WSC); increased levels of lactic acid; and lower levels of acid detergent fibre (ADF) when compared with untreated canelage (fermented, whole-plant sugar

TL;DR: In this paper, eight modifications of the original procedure for the determination of neutral detergent fibre (NDF) in feeds were compared and two modifications yielded NDF values that were not significantly different from the original method.

TL;DR: This review embraces work on the use of low-glucosinolate rapeseed meal (LG-RSM) for pigs, mainly published since 1977, and suggests it seems possible to replace at least half of the supplementary protein with LG- RSM in cereal-based diets for growing-finishing pigs without impairing performance, provided that the lower ME content of RSM is balanced.

TL;DR: DMBP is a useful ruminant feed containing 12.5 MJ metabolisable energy and 79 g digestible crude protein/kg DM that is not well suited to pigs and poultry.

TL;DR: Ammonia-treated or untreated barley straw supplemented with urea was given as the only feed to two groups of Friesian heifers weighing approximately 550 kg as discussed by the authors.

TL;DR: The water-soluble N appeared to be retained by sheep as well as urea-N given with untreated straw; digestibility coefficients obtained in vivo, and by nylon bag incubation, suggested that N in CWOM was largely unavailable.

TL;DR: In the combined analysis of four starter trials, pigs feeding on diets containing virginiamycin tended to eat more and grow faster than pigs fed on the control diet, but feed efficiency was not different, and daily gain, daily feed intake and feed efficiency were not improved by the addition of lactobacillus probiotic to starter diets.

TL;DR: In this article, three experiments were conducted with hammer-milled (10mm screen) rice and barley straw treated with urea solution, alone or with urease enzyme, in sealed polythene bags.

TL;DR: Up to 20% Canola seed can be used in steam-pelleted diets based on maize and soya bean meal without altering broiler performance, and marked improvements in weight gain and feed gain ratios and fat digestibility are noted.

TL;DR: It was concluded that in some samples of triticale, a growth inhibitor was present but that triticalse could replace up to 50% of the wheat in the diet of grower/finisher pigs without detrimental effects.

TL;DR: Barley straw in a 10-t stack was treated with anhydrous ammonia (40 kg t −1 straw dry matter) for a period of 12 days as discussed by the authors and the total nitrogen content of the straw increased from 6.7 g kg −1 before treatment to 20.7g kg − 1 at day 54.

TL;DR: It is concluded that, relative to other lupin species, L. albus has a more favourable amino acid profile for its utilisation in cereal-based diets for animals, particularly if the energy source is wheat, which is deficient in threonine.

TL;DR: In this article, sugar cane bagasse previously dried to a water content below 25% was sprayed with equal quantities of sodium hydroxide solutions to supply 0, 20, 40 or 60 g alkali/kg of dried product and ensiled for 90 days.

TL;DR: In this paper, the digestibility of treated maize cobs was studied using Romney Marsh wether sheep in a 2 × 3 factorial design, and three chemical treatments were applied to each grinding: distilled water, sodium hydroxide, and Magadi soda.

TL;DR: In this article, the authors used polythene bag silos to ensil the whole-crop wheat and barley at the soft-, medium-and hard-dough stages of grain development.

TL;DR: There was a significant increase in neutral detergent fibre (NDF) and acid detergence fibre (ADF) digestibility due to supplemental S, regardless of S source and no effect of animal adaptation to nitrate was evident.

TL;DR: In this article, the authors evaluated the HCN content of Para-Rubber seed and its products, including the autoclaved and fermented oil meals, at post-harvest intervals from 1 week to 9 months of storage at room temperature.

TL;DR: It was concluded that when nutritive value is predicted by NIRR the estimates may often be biased according to the grass species, plant part or physical form of the sample tested and that the pattern of bias may be complicated.

TL;DR: General conclusions for beta-carotene losses from forage during silage-making and feeding cannot be drawn for all forage crops nor even for individual botanical families.

TL;DR: The dry matter digestibility in vitro (IVDMD), after 21 days of ensiling was greater for silage containing the wheat straw base than for that with the rice hull base, and Whey improved the IVDMD of the wheat Straw base silage but not that of the rice Hull Base silage.

TL;DR: In this article, the chemical composition of exocarp and mesocarp of Prunus amygdalus Batsch (almond hulls) was studied for five years.

TL;DR: In this article, a mature perennial ryegrass with a digestible organic matter in vitro (DOM) content of 544 kg−1 dry matter (DM) was treated with urea prills at 0, 30 and 60 kg− 1 DM.

TL;DR: In this article, the metabolic energy (ME) measurements were made on chicks and cockerels on diets comprising 770 g/kg of maize, barley or wheat milled to three moduli of fineness and given either as a mash or pelleted and crumbled.

TL;DR: In this article, the authors show that steam-pelleting or particle size of the diet had no significant effect on the apparent digestibility of dry matter (DM), modified acid detergent fibre and gross energy (b) digestible (DE) and metabolisable energy (ME) contents.

TL;DR: In this article, the authors examined the ability of three absorbents (sodium bentonite, a hydrolyzed starch-polyacrylonitrile graft co-polymer (SGP), and alkali-treated straw) to stem the flow of effluent from silage made from low dry matter grass.
