Abstract:

A study was conducted (I) to determine rumen degradability (in sacco) of dry matter (DM) and neutral detergent fibre (NDF) of the most important grass species grown in the Czech Republic, (II) to compare grass species (n = 5) according to calculated degradation parameters, and (III) to establish prediction equations for degradation parameters from chemical composition. Forty samples of the most important grass species (Dactylis glomerata, Phleum pratense, Lolium perenne, Festuca arundinacea, Felina hybrid) were harvested in 2004 and 2005 and analyzed for chemical composition, and DM and NDF in

Energy content is an important criterion for evaluation in lucerne breeding. The in sacco method was used to investigate the phenotypic variation in the kinetics of degradation of dry matter and fibre for 15 lucerne cultivars grown in one location, and to compare these kinetic parameters with laboratory analyses of dry matter solubility, fibre content (NDF, neutral detergent fibre), and fibre solubility. Bags containing forage samples were incubated for 2, 4, 8, 12, 24, 48, and 72 h in 3 fistulated Holstein cows. Dry matter and NDF degradation curves were modelled with a sigmoid curve with 3 p

Fat is often fed to sheep and cattle as a means to increase dietary energy concentration. There is increasing interest in the supplementation of ruminant diets with fats and oils. However feeding fat may reduce dry matter digestibility, and feeding ruminant animals large quantities of fat (>5% of total dry matter intake) can result in a marked negative effect on fibre and dry mater intake. The aim of the present study was to investigate the effect of fat supplementation on ruminal degradation of dry matter (DM) and neutral detergent fiber (NDF) of sheep fed a tropical hay.

In vitro dry matter degradation of the TMR at 12 h of incubation was increased by 15% when enzymes were added to the concentrate portion, and by 17% when added to the premix portion of the TMR (P < 0.05), but adding enzymes to the supplement (pelleted portion of the concentrate) had no effect.

ABSTRACTThirty-two Friesian cows in early lactation were given one of tour completely mixed diets based on equal proportions of barley straw and concentrate. Two varieties of barley straws had been identified as varying in degradation characteristics (Corgi and Gerbel) and the straws were either given untreated or treated with anhydrous ammonia. The ad libitum intake for 10 weeks closely reflected degradation characteristics. For Corgi, treated and untreated and Gerbel, treated and untreated the 48·h degradabilities were 71·9, 66·8, 61·9 and 52·2 (g/100 g) respectively. The voluntary intakes o

Abstract:

The quality of alfalfa would be greatly improved by an increase in its ruminal undegradable protein (RUP) concentration. Protein degradation rate (PDR), in vitro dry matter digestibility (IVDMD), leaf weight ratio (LWR), dry matter yield (DMY), total nitrogen (TN), in vitro RUP (expressed on both TN, RUP-TN, and dry matter basis, RUP-DM), acid detergent fiber (ADF), and neutral detergent fiber (NDF) concentrations were determined in 27 alfalfa cultivars. Cultivars were seeded in triplicate on 2 consecutive years and evaluated during the 2 subsequent production years with two harvests per year.

The goal of this study was to ascertain the impact of soybean meal's temperature and heating duration as undegraded protein (UDP) on Bali cattle's dry matter (DM) and organic matter (OM) degradation kinetics. Soybean meal is a feed ingredient with high protein content, which is about 48%, and is rapidly degraded in the rumen. In this investigation, a factorial design was employed with the first factor being temperature (60, 80, 100, and 120°C), and the second factor being heating time (10, 20, 30, and 40 min).

The hypotheses for grazing dairy cows were: (i) the consumption of Persian clover would result in a more rapid rate of degradation and less stable rumen fermentation patterns compared with perennial ryegrass; and (ii) the greater intake of cows grazing at high compared with low pasture allowa
