Comparability of portable nanoparticle exposure monitors.

Five different portable instrument types to monitor exposure to nanoparticles were subject to an intensive intercomparison measurement campaign. Four of them were based on electrical diffusion charging to determine the number concentration or lung deposited surface area (LDSA) concentration of airborne particles. Three out of these four also determined the mean particle size.

Effect of whole cottonseed on serum constituents, fragility of erythrocyte cells, and reproduction of growing Holstein heifers.

A 431-d experiment was conducted to determine the effects of whole cottonseed containing gossypol (7400 mg/kg) on growth and development from weaning until pregnancy in Holstein heifers. Treatment diets (n = 5) contained 0, 15, or 30% whole cottonseed. The basal diet included alfalfa hay, corn grain, soybean meal, molasses, and dicalcium phosphate.

Effects of whole cottonseed and live yeast culture on ruminal fermentation and fluid passage rate in steers.

The effects of adding whole cottonseed (WCS) and live yeast culture (YC) to a diet of 60% alfalfa and 40% concentrate on ruminal fermentation and liquid dilution rate in steers were examined in two trials. Twelve ruminally cannulated Hereford steers (approximately 420 kg) were used. Concentrates were 1) a basal grain mix composed of ground corn, ground barley and rice bran, 2) basal mix with 10% WCS, 3) basal mix with 1.

Kochia (Kochia scoparia) toxicosis in cattle: results of four experimental grazing trials.

Four kochia grazing trials were completed over a period of 3 years. Yearling steers were allowed to graze pure stands of irrigated and fertilized kochia (Kochia scoparia) for periods of 14 to 105 days. A total of 116 steers were given kochia as their sole forage.
