The effect of zinc levels on nitrogen retention in preadolescent children
… on whole egg protein. The sources and amounts of nitrogen were: food, 4.18 and supplements, 0.14 g/day. One group received these same amino acids plus a zinc supplement of 5.0 mg/day. One group received an isonitrogenous amount of ammonium citrate matching the nitrogen contained in the amino acids …

The Effects of Biochar and Reactive Iron Additions on Soil Carbon and Nitrogen Retention
… Virginia to improve the accumulation and retention of C and nitrogen (N). I used a field experiment to compare the effects of three types of locally-produced biochars applied with and without an organic N fertilizer (blood meal) on soil C and N availability. I then used an incubation …

EFFECT OF PROTEASE SUPPLEMENTATION IN BROILER FEED ON GROWTH PERFORMANCE, CARCASS YIELD AND TOTAL NITROGEN RETENTION IN FECAL MATTER AND LITTER
… broiler performance, carcass yield, and nitrogen retention in fecal matter and litter. Total of 4,800 female (Ross 708) birds split into 96 floor pens, and randomly assigned to one of four treatment groups. Birds were placed within 96, 5’x10’ floor pens in a randomized-block design at the …

Effects of elevated carbon dioxide on Bromus rubens and nutritional consequences for the desert tortoise
… using a common diet component, Bromus rubens. Nitrogen balance was monitored for tortoises fed pelleted diets reflecting the nitrogen levels of Bromus plants grown under elevated and ambient CO2 conditions, with varying potassium levels (3.5% and 1.4% DWB). Nitrogen content in the diet …

Limiting amino acids for growing cattle fed diets based on corn and corn gluten feed
… for total fecal and urine collections to measure nitrogen retention. Data were analyzed as a Latin square with fixed effects of treatment and period and random effect of steer. Means were separated with pairwise t-tests. Compared to nitrogen retention of control (26.0 g/d), MIX (33.2 g/d; P<0.01), …

Amino acid requirements of growing steers
… infused L-methionine (4 replications/treatment). Nitrogen retention increased linearly in response to casein infusion and in response to infusion of the amino acid mixture when methionine was supplemented. Methionine supplementation increased N retention when steers were infused with 200 or 300 …

The relationship between zinc and protein in pregnant women
… high zinc (23.36 ± 2.59, on supplement), low nitrogen (below 10 gm/day) or high nitrogen (above 10 gm/day). Zinc and nitrogen data were determined from food, beverage and supplement intakes and urine and fecal excretions. Zinc retentions were 3.32 ± 6.33 in the supplemented group, 4.94 ± 10.91 …

Wheat and coconut flour protein utilization by six young college women
… to each Nutribun supplement. Both diets were isonitrogenous. Nitrogen determinations were made on the Nutribuns, the food composite, the feces, and the urine. Daily urinary creatinine analysis was also carried out. Observations were made on the nitrogen retention of the subjects given the two …

The Influence of Switchgrass Establishment on Soil Organic Matter Pools in an Agricultural Landscape
… biogeochemical cycles, particularly carbon and nitrogen. Conventional row-crop agriculture accelerates the decomposition of soil organic matter, contributing to atmospheric carbon and declining soil fertility. Planting perennial warm season grasses is a useful management alternative to row crop …

Fermentation, utilization, and palatability of swine waste ensiled with various proportions of ground orchardgrass hay or ground corn grain
… soybean meal diet than any of the other diets. Nitrogen retention was negative (P<.05) for sheep fed the silages. Organic matter digestibility of the swine waste calculated by difference was over 60 percent, In the sheep palatability trial, dry matter intake was similar between the diets. Ina …

The nutritive value of soy flour and soy protein isolate for human adults
A 12-day nitrogen balance study was designed to determine the protein nutritive value of soy flour and soy protein isolate in human adults. By equalizing the essential amino acid patterns of the flour and the isolate, it was considered possible to measure any difference in nutritive value of the …

Quantification and characterisation of nutrients in Senegalia Mellifera milled biomas, feed intake and nitrogen balance in female boer goats fed with Senegalia Melifera bush-based feeds
… matter intake (DMI), apparent digestibility and nitrogen retention in female Boer goats fed with Senegalia mellifera bush based feeds. Wood ash (WA), Polyethylene glycol (PEG, 6 000) and Biochar were evaluated as tannin deactivation methods. The milled biomass of S. mellifera was mixed using a …

The ecological role of beavers (Castor canadensis) in a Southwestern desert stream
… to determine if beaver ponds alter the system retention of nitrogen, a nutrient that often limits primary production in streams of the western United States; The spatial prevalence of beaver ponds along Meadow Valley Wash, a perennial stream in southeast Nevada, was determined by surveying 31.5 …

The influence of various levels of readily-available carbohydrates in purified rations on cellulose digestibility by sheep
… affect digestibility of ration components and nitrogen balance. Cellulose digestibility tended to be higher for the 8% ration. Energy and dry matter digestibility tended to be higher for the supplemented rations. In experiment 2B, two metabolism trials were conducted with twelve wethers to …

Fermentation characteristics, nutritional value and palatability of ensiled seafood wastes and low quality roughages
… fish, compared to diets containing ensiled crab. Nitrogen retention was positive for sheep receiving all diets. Nitrogen retention was higher (P <.01) for animals fed the crab silage diets, compared to those receiving diets containing fish silage. There was a trend for P absorption to be higher in …

Spatial and Temporal Variability of In-Stream Functioning within a Forested, Headwater Piedmont Watershed
… throughout its headwaters may buffer increased nitrogen inputs by converting them to stable forms, ultimately through denitrification to N2 gas. However, the temporal environmental factors controlling baseflow nitrogen retention are poorly understood, particularly temperature, shading, and …

Utilization of abomasally infused ribonucleic acid and deoxyribonucleic acid in sheep
… twice daily, of a basal ration supplying 7.1 g nitrogen. In addition, the lambs received twice daily infusions of either soy protein, RNA, DNA, or a 1:1 combination of RNA and DNA or a sham infusion. Tris buffer was used as the solvent for RNA and DNA, the carrier for soy protein and the sham …

Influence of energy concentration of fattening rations on nitrogen utilization by steers
… to study the effect of energy concentration on nitrogen metabolism and digestibility. The experimental design consisted of two randomly selected 3 x 3 Latin squares. Three fattening rations were ted which contained 1133, 1164 and 1222 kcal. digestible energy per lb. feed and 12.18, 12.51 and …
