Lactational Evaluation of Protein Supplements of Varying Ruminal Degradability
… of the trial (P >.2). Varying degrees of protein degradability within the range of this study did not affect animal performance indicating that all of these protein supplements were adequate in supporting milk production with no contrary affect to the animal.</p>

Ruminal degradability of subfractions of protein sources as determined by gel electrophoresis
Degradability in the rumen of several protein sources was determined by suspending from 12 to 13 g of feedstuff in dacron bags into the rumen for 0, 2, 6, 12, 24, 36, 48, and 72 h. Rumen cannulated lactating Holstein cows consuming a diet of corn silage, alfalfa, soybean, and high moisture corn …

Effect of roughage to concentrate ratio on ruminal fermentation and protein degradability in dairy cows
… rumen parameters and ruminal crude protein (CP) degradability. The in situ method was used to determine the ruminal protein degradability of sunflower oilcake, cottonseed oilcake and roasted soya. The three treatments differed in roughage:concentrate ratio, being 60:40 (Treatment UP 60), 45:55 …

Solubility, degradability and utilization by ruminants of broiler litter processed by ensiling, deepstacking and composting
… litter had 12.2, 25.2, 29.1, and 25.5% protein undegradability, respectively. Feeding litter increased dietary undegraded N flow and decreased microbial N flOw, compared to feeding soybean meal. Efficiency of microbial protein synthesis was not affected by N source. Available N (g/d) in the small …

Microbial Degradability of Terrigenous, Marsh-Exported, and Estuarine Colored Dissolved Organic Matter in Long Island Sound
<p>The Long Island Sound is one of the world's most urbanized estuaries, polluted from excess nutrients which impact the quality of water through increased biological productivity. Dissolved organic matter (DOM) is a sensitive indicator of anthropogenic pollution and nutrient enrichment in coastal …

Effects of ruminal nutrient degradability on volatile fatty acid dynamics, ruminal epithelial gene expression, and post-absorptive system
… changes on diets differing in nutrient degradability and how the post-absorptive system adapts in response.

Effect of dietary protein degradability and fat on rumen, blood and milk components of Jersey and Holstein cows
… to investigate the effects of dietary protein degradability and supplemental fat on rumen, blood, and milk components. Diet dry matter contained 16% CP with two levels of rumen undegradable protein (RUP) obtained by substituting blood meal for soybean meal. Treatments were 29% RUP, 0% added …

Responses to abomasal infusion of casein, hydrolyzed casein or methionine-lysine and dietary protein degradability in lactating cows
… or 11.3 g L-methionine-30.1 g L-lysine and rumen degradability of dietary protein were studied in eight Holstein cows during mid-lactation. Basal diets contained com silage, com and either soybean meal or 60:40 soybean meal:corn gluten meal, and had estimated rumen degradabilities of 70 and 60.5%. …

Protein preservation and rumen degradability of ensiled forage, previously treated with microwave or steam heat, formic acid, or anhydrous ammonia
… aerobic stability than direct-cut silage. Rumen degradability of silage CP and OM from both experiments were evaluated. In Experiment 1, CP degradability of microwaved or steamed silages was 8 to 26% less than unheated silages, but all had similar undegraded CP after incubation for 72 h. In …

Chemical composition, ruminal degradability and in vitro digestibility of dry matter and crude protein of dichrostachys cinerea and bauhinia thonningii leaves.
… to determine the chemical composition, ruminal degradability and in vitro digestibility of dry matter (DM) and crude protein (CP) of Dichrostachys cinerea and Bauhinia thonningii leaves. The browse tree leaves were harvested in the wild in Shayandima, Limpopo province. The leaves were collected, …

Evaluation of ruminal escape potential of crab meal and other protein supplements and influence of steam explosion of ruminal degradability of crab meal
… in lambs fed the U diet. In Expt. 3, the ruminal degradability of DM and CP of crab meal and other protein supplements were estimated in situ, in a ruminally cannulated steer. The highest DM degradability was for SBM. The ruminal escape of protem was lowest (P < .05) for SBM (23.2%) and the …

Fiber and nitrogen fractions of forages and by-product feeds determined by in vitro and in situ procedures
… and nitrogen fractions, and in vitro and in situ degradability of forages and by-product feeds, and to compare in vitro methods of estimating rumen degradability with the in situ bag technique. Feeds analyzed with number of samples in parentheses included alfalfa as baled hay (23), alfalfa ensiled …

Effects of autolyzed yeast (saccharomyces cerevisiae) on feed degradability and digestibility; performance, rumen environment, and physiological biomarkers of Holstein cows fed a high starch diet
… apparent digestibility, and in situ degradability, gene expression, and the rumen microbiome in lactating Holstein cows. Fifteen multiparous rumen-cannulated Holstein cows were assigned to 1 of 5 treatments in a replicated 5 × 5 Latin square design balanced to measure carryover …

Effect of maturity on rumen degradation of tropical and temperate forage cell wall polysaccharides from leaves and stems
… understanding the factors that influence the degradability of forages by ruminants. In the first part of the study, the degradability of leaf and stem fractions of two mature tropical forages, bana grass (Pennisetum purpureum) and silverleaf desmodium (Desmodium uncinatum) were determined by …

Hull, ferulic acid, para-coumaric acid content and particle size characteristics of various barley varieties in relation to nutrient availability in ruminants
… to polysaccharides, therefore, limit cell wall degradability in the rumen. Paricle size of barley grain also affects the digestion of barley in the rumen. The objective of this study was to evaluate a set of barley varieties grown in Saskatchewan (Canada) and provided by Crop Development Center …
