TL;DR: Results obtained establish the pressure transducer as a suitable tool for determining the fermentation kinetics of ruminant feeds and ranking them with respect to their in vitro fermentability.

TL;DR: A total of 285 samples representing 51 feedstuffs used in Belgian feed-mills were quantitatively analysed for phytase activity, phytate-P and total P as mentioned in this paper.

TL;DR: Three double-marker systems were used to calculate duodenal flows of organic matter, non-ammonia N (NAN), microbial N and NDF, and the most suitable was AIA, followed by INDF6, INDF41 and IADF41, and ADL was the least acceptable marker.

TL;DR: There are only moderate differences in the digestibility of individual FA, which appears to be higher for palmitic and stearic acids than for other saturated FA, and for oleic and linoleic acids more than for stearics and linolenic acids.

TL;DR: Peas and field beans have been increasingly grown in Europe during the last 15 years, to improve self-sufficiency in protein-rich feedstuffs and it seems possible to improve the nutritional value of legume seeds by selective breeding.

TL;DR: The enzyme was found to maintain its activity through conditioning temperatures, manifested by a positive effect on performance digestibility of nutrients and gut morphology and an increment in the number and size of globet cells of barley-fed birds.

TL;DR: Addition of a yeast culture with Saccharomyces cerevisiae improved NDF digestibility and propionate molar percentage; it also increased ruminal protozoa population, which could partially explain NDF Digestibility changes.

TL;DR: It is demonstrated that a low dietary inclusion rate of a crude enzyme preparation that has high activities of two enzymes (xylanase and cellulase) can considerably improve the nutritional value of barley and rye, probably that of wheat, but not that of corn.

TL;DR: The influence of peptides, amino acids and urea on microbial activity in the rumen of sheep receiving grass hay and on the growth of rumen bacteria in vitro is studied.

TL;DR: Both defaunation and LSO supplementation decreased the amount of OM apparently digested in the rumen and increased the flow of microbial nitrogen at the duodenum, leading to an increase in the efficiency of microbial protein synthesis.

TL;DR: In this article, eight Mediterranean browsing species were analysed for neutral and acid detergent fibre, lignin, crude protein, total extractable phenols (TEPH), tannins (TETa), condensed tannin (vanillin-HCl) (TECTa) and extractable or total proanthocyanidins.

TL;DR: Four balance trials were performed, each using four growing pigs initially weighing about 30 kg, and Supplemented microbial phytase increased P availability from 18% to 56% in maize, from 62% to 74% in wheat, and from 52% to 67% in triticale.

TL;DR: In this article, the authors evaluated 15 leguminous browse plants harvested in Nigeria with respect to their proximate chemical composition, mineral (trace and major) content, phytin, Phytin-phosphorus and oxalate constituents.

TL;DR: The results from this experiment suggest that partial enzyme inactivation occurs at pelleting, and Digesta β-glucanase activity correlated linearly with viscosity, which in turn correlated highly with bird performance.

TL;DR: The results of this study showed that crude U. rigida is not a suitable ingredient for poultry diets, at least at inclusion rates of 100 g kg−1 or higher; however, seaweed did not have an antinutritive effect, because the addition of seaweeddid not modify the TMEn of the rest of the diet (standard diet or glucose).

TL;DR: In this article, five roosters were fed 30 g of each FM by crop incubation to measure digestibility and the true metabolizable energy of the FM was (kJ g −1 ): 207 kPa, 15.04, 10.19, and 14.24.

TL;DR: The results of a study into the effects of calibration method, residual moisture content and sample particle size on the prediction of the organic matter digestibility in vivo of grass silages by near infrared reflectance spectroscopy are reported in this paper.

TL;DR: In this article, the authors measured gas production from leaves of Cistus incanus, Carpinus duinensis, Quercus coccifera and Fraxinus ornus during 96 h incubation with or without addition of insoluble polyvinylpolypyrrolidone (PVP).

TL;DR: The effects of cultural practices and drying facilities on the biological processes during drying are discussed in this paper, where the effects of drying temperature on forage quality analysis are discussed. But the analysis will probably never be perfect.

TL;DR: The difference in allantoin and total purine excretion rates between KK cattle and swamp buffalo given the same diet and level of feeding is apparently the result of physiological and/or ruminal microbial differences between the species.

TL;DR: There was considerable intraspecies variability in CE as indicated by the high coefficients of variation (CV), which suggests that selection for lower inhibitor levels is possible, and there was no significant relationship between seed weight and TIA in any of the species investigated.

TL;DR: Legumes fed together with cottonseed cake as a supplement to maize stover increased digestibility of most dietary soluble and cell-wall constituents compared with legume supplements alone.

TL;DR: Results suggested that for dromedaries 1 day of measurement may be sufficient for palatability assessment while for sheep this period should be extended to 5 days for better accuracy of intake prediction.

TL;DR: Comparison of the three microbial markers showed that microbial protein entering the duodenum was underestimated by DAPA only when the number of protozoa in rumen fluid was high, and it is possible to avoid invasive cannulation technique without reducing the accuracy of estimation of microbialprotein entering the small intestine.

TL;DR: The values obtained with the supplements fall within the range estimated for the efficiency of microbial protein formation in the rumen of ruminants.

TL;DR: The interaction between processing (pelleting vs. extrusion) and grain (wheat vs. barley) for liveweight at Days 21 and 39 was significant, indicating a greater negative impact of extrusion on broiler feed containing barley.

TL;DR: Low animal performance on gliricidia-supplemented diets was likely due to lower available dietary energy resulting in lower N digestion and assimilation, and high costs of grain imports may economically favor lower rates of gain in tropical areas of the world.

TL;DR: The practical implication is that with low quality straw, supplementation of starch concentrate up to 31% of the whole diet increased both voluntary food intake and the supply of microbial protein per unit of DOMI.

TL;DR: In this paper, a study was made of silages preserved with formic acid (4.6 g kg−1), in which the content of residual sugar in the aqueous phase was at least 10 g l−1, thus permitting lactic acid fermentation.
