A mature, rumen-cannulated steer fed Coastal Bermuda grass hay for 8 weeks was adapted to a high-grain ration by stepwise increases in grain over a period of 4 weeks. The grain rations had concentrate-to-roughage ratios of 40:60, 70:30, and 85:15 and were fed for 10, 7, and 11 days, respectively. Numerical estimates of lactate-utilizing bacteria in ruminal(More)
Microcytosis is common in dogs with congenital portosystemic shunts (PSS) and acquired liver disease. The objective of this study was to determine if microcytosis could be induced in normal dogs by surgical creation of PSS, and to characterize the changes in hematology and iron status. Hematocrit, mean cell volume, mean cell hemoglobin, and mean cell(More)
Terahertz spectra of four alanine-rich peptides with known secondary structures were studied by terahertz time domain spectroscopy (THz-TDS) and by Fourier transform infrared spectroscopy (FTIR) using a synchrotron light source and a liquid-helium cooled bolometer. At ambient temperatures the usable bandwidth was restricted to 0.2-1.5 THz by the absorbance(More)
Kinetics of gentamicin (2.2 mg/kg of body weight) were investigated in 7 sheep after IV bolus administration. The mean serum concentration profile could be described by a 2-compartment open model with a distribution rate constant (alpha) of 3.112 +/- 1.681 hour-1 [half-life, t1/2(alpha) = 17.22 +/- 8.63 minutes] and an overall elimination rate constant(More)
Rapid intravenous administration of a single bolus of secretin caused a marked decrease in both amplitude and frequency of rumen contractions, whereas pancreozymin administration caused a decrease in frequency but an increase in amplitude of rumen contractions. Alpha receptor blockade with phenoxybenzamine or beta receptor blockade with propranolol did not(More)
Current medical management of dogs with portosystemic shunt (PSS) includes dietary protein restriction. After establishment of baseline values, 32 dogs underwent portosystemic anastomosis to induce PSS. They were assigned to 1 of 4 dietary treatments, and given 11 or 24% crude protein (CP); 20% of the protein was derived from branched chain or aromatic(More)
Litters of pigs were allotted to one of three dietary treatments. Treatment 1 (T1) consisted of a corn-soybean meal starter diet. Pigs fed treatment 2 (T2) received a steamed, rolled oat groats-casein diet and pigs in treatment 3 (T3) remained with the sow. Four pigs/treatment were used to investigate the difference in performance and the cause of(More)
