Branched -Chain Amino Acid Nutrition of Grow-Finish Pigs and Young Chicks
… requirement for maximal weight gain and minimal plasma urea-nitrogen (PUN) of growing (25 to 45 kg) pigs. An Ile-deficient basal diet (0.30% true digestible Ile) utilizing red blood cells (RBC) was developed and validated. Digestibility of Ile in the RBC product was determined in both …

Utilização do grão tostado de soja (Glicine max (L) Merril) na alimentação de vacas em lactação
… and kept under steeping were included in isonitrogenous and isocaloric lactating dairy cows rations and evaluated in comparison to raw soybeans, with two other protein sources as references. There were no differences (P>0,05) between the roasted and raw soybeans diets related either to dry …

Nitrogênio Ureico no Leite (NUL) e no Plasma (NUP) de vacas leiteiras suplementadas com níveis crescentes de proteína bruta no concentrado
… to dairy cows under grazing. The values of milk urea nitrogen (NUL) and plasma urea nitrogen (NUP) obtained, had a linear increasing effect (P<0.05) in the diets according to the crude protein increase (CP) levels, where Level with 18% of CP obtained values higher than recommended by the …

Influence of Methionine on Growth and Nitrogen Balance in Weanling Quarter Horses
… the influence of methionine on growth and nitrogen retention. Weanlings were housed by block and individually fed 1 of 4 concentrate diets twice daily at 1.5% BW (as fed). Weanlings were randomly assigned to 1 of 4 treatments: basal (0.20 MET), basal + 0.03% methionine (0.23 MET), basal + …

Nitrogen Metabolism in Bos indicus and Bos taurus Cattle Consuming Low-quality Forages
… and two levels (50 and 100 mg N/kg BW) of an isonitrogenous supplement (27% CP), either high (H; 72%) or low (L; 28%) in DIP. Forage OM intake (FOMI) was greater for Bt than Bi (P = 0.05). Supplementation increased FOMI in both Bt and Bi (P < 0.05). Organic matter digestibility (OMD) was greater …

Amino acid requirements and low crude protein, amino acid supplemented diets for swine and poultry
… and sulfur amino acids in 90-kg barrows using plasma urea nitrogen as the response. These experiments indicate a TD Lys requirement of 0.57% and there was no response to TD sulfur amino acid concentrations above 0.27%. Six experiments were conducted to evaluate the Ile requirement of 80- to …

Evaluation of Supplementing Brewer's Yeast to Lactating Dairy Cows
… interaction (P < 0.01). A treatment effect for plasma urea nitrogen (PUN) was detected (P < 0.01) and a treatment by group interaction for glucose was determined (P < 0.01). No statistical significance on treatment effects were determined for ruminal parameters and total-tract digestibilities. …

Nutrient Utilization in Pigs and Chicks Treated With Lipopolysaccharide: Lysine, Threonine, Arginine, Sulfur Amino Acids and Vitamin E
… was induced by LPS as indicated by increased plasma levels of the cytokines tumor necrosis factor-$\alpha$ (TNF-$\alpha$ and interleukin-6 (IL-6), and the catabolic hormone cortisol. The increased secretion of cortisol in pigs injected with LPS was followed by an increase in protein …

Growth of Thoroughbreds fed Different Levels of Protein and Supplemented with Lysine and Threonine
… (TP), albumin (ALB), creatinine (CREA), and plasma urea nitrogen (PUN). Effect of diet and time were evaluated by analysis of variance with repeated measures. No differences were found in physical measurements between the CS and LTS groups (ADG 0.8(0.4 kg/day, BC 4.9(0.05) for the …

Intake, growth and rate of digesta passage in ruminating calves fed sodium bicarbonate and disodium phosphate
… blood samples for determination of glucose and plasma urea nitrogen at 8, 11 and 14 wk. Rate of passage was determined using ytterbium and cobalt EDTA to follow the particulate and liquid phases of digesta respectively. A digestion trial was carried out concurrently with rate of passage …

Growth Performance, Nutrient Utilization, and Metabolic Profile of Dairy Heifers Fed Diets High in Distillers Grains with Different Forage to Concentrate Ratios
… There was a linear increase in concentration of plasma linoleic acid with increasing amount of DDGS and a linear and quadratic response for arachidonic acid. Total fatty acid (FA) and polyunsaturated fatty acids (PUFA) were linearly increased with a quadratic response with 30DG and 50DG having …

Partitioning of nitrogen by lactating cows fed diets varying in nonfibrous carbohydrate and rumen undegradable protein
… and lactational parameters. Diets were isonitrogenous (17.4% CP) and structured in a 2 x 2 factorial arrangement with levels of NFC at 41 or 47% of dietary OM and RUP at 27 or 41% of dietary CP with inclusion of corn gluten meal, fish meal, and feather meal to increase dietary RUP. When …

Isoquinoline alkaloids in diets for young growing pigs improve nutrient digestibility and gut health
… decreased (quadratic; P < 0.05) during phase 1. Plasma urea nitrogen tended to increase in phases 2 and 3 (linear; P < 0.10) if IQ was added to the diet and total plasma protein quadratically increased (P < 0.05) in phase 1. In the ileum, crypt depth and lamina propia thickness decreased …

Effects of Differences in Dietary Protein and Varying the Interval from Collection of Bovine Embryos to Freezing on Embryo Quality and Viability
… were analyzed to assess dietary effects on plasma urea nitrogen (PUN). Mean levels of PUN were higher (P < 0.01) in cows fed the LITTER or SBM diet (16.3 mg/dL, LITTER; 21.8 mg/dL, SBM; 9.7 mg/dL, CON) than in cows fed the CON diet. Additionally, concentration of PUN was higher in cows fed …
