Two studies were conducted to examine the possible reduction in odors in fat and loin samples from boars treated with porcine growth hormone (pGH). In Exp. 1, boars were treated with either 0 (control: C), 3.5, or 7 mg of pGH daily from 72 to 119 kg BW. Treatment with pGH improved feed efficiency (P less than .05) but did not affect ADG, concentrations of testosterone in plasma, or aroma of coo...

The objective of Exp. 1 was to compare the effects of virginiamycin (VM; 0, 175, or 250 mg x animal(-1) x d(-1)) and monensin/tylosin (MT; 250/ 90 mg x animal(-1) x d(-1)) on ruminal fermentation products and microbial populations in cattle during adaptation to an all-concentrate diet. Four ruminally cannulated, Holstein steers were used in a 4x4 Williams square design with 21-d periods. Steers...

BACKGROUND L-Arginine, the substrate of nitric oxide (NO) synthase, and N(G)-monomethyl-L-arginine (L-NMMA), a competitive inhibitor of endothelial NO synthase, are used to analyze endothelial function of the renal vasculature. However, little is known about the appropriate dose of L-arginine to be used and the duration of action of L-arginine and L-NMMA. METHODS Twenty-nine healthy male subj...

Poor subsoil properties are difficult to ameliorate and detrimental soil fertility crop yield. The effects of loosening (L) + straw (LS) ?60 Mg ha–1 into the (25–40 cm depth) on yield, water flow, nitrogen (N) balance components under bare conditions a barley (Hordeum vulgare L.) were investigated in an about 21-mo lysimeter study compared with control treatment. Undisturbed columns (n = 12) ex...

Five lactating Holstein cows with ruminal and duodenal cannulas were used in a 5 x 5 Latin square to determine the site of mineral absorption and effects of sources and amount of dietary fat on apparent absorption. Cows were fed (DM, 17.4 +/- .8 kg/d) chopped alfalfa hay, alfalfa haylage, corn silage, and concentrate at 1:1:1:2 (DM) at 12-h intervals. Calcium salts of palm fatty acid distillate...

We examined the interrelation between systemic hypertension, hyperlipidemia, and progressive renal injury in experimental glomerulonephritis. Induction of nephrotoxic serum nephritis in Sprague-Dawley rats led to systemic hypertension and hyperlipidemia. Four groups of rats were studied over a 16-week period: (1) untreated nephritic rats; (2) nephritic rats treated with hydralazine, reserpine, ...
