The objective of this study was to examine the effect isonitrogenous substitution solvent-extracted soybean meal (SBM) with canola (CM) on enteric CH4 production, ruminal fermentation characteristics (including protozoa), digestion (in situ and apparent total-tract digestibility), N excretion, milk production dairy cows. For purpose, 16 lactating Holstein cows, which 12 were ruminally cannulate...

Handheld optical sensors recently have been introduced to the agricultural market. These handheld sensors are able to provide operators with Normalized Difference Vegetative Index (NDVI) data when cloud cover prevents acquisition of satellite or aerial images. This research addressed the sensitivity of the GreenSeeker handheld optical sensor to changes in orientation and height above a ryegrass...

2 experiments were conducted to determine the generality of the finding by Stavrianos (1945) that judged slant of plane rectangular figures varies directly with size. In Experiment I, equal-slant contours were obtained from 54 undergraduate Ss for 14 rectangles whose lengths varied in equal log steps from 1.0 to 42.2 cm. with a reference stimulus of 7.5 cm. In Experiment II, 72 Ss were tested o...
