The effects of dietary cation-anion difference and dietary buffer for lactating dairy cattle under mild heat stress with night cooling.

The objective of this study was to investigate the interactive effect of DCAD and dietary buffer supply on DMI, ruminal fermentation, milk and milk component yields, and gastrointestinal tract (GIT) permeability in lactating dairy cattle exposed to mild heat stress. A total of 16 lactating Holstein cows, including 8 ruminally cannulated primiparous (80 ± 19.2 DIM) and 8 noncannulated multiparous (136 ± 38.

Examination of the validity of the 'Papadum test': An alternative to the clock drawing test for people with low levels of education.

: The clock drawing test (CDT) is a widely used cognitive screening test. However, CDT performance is affected by education. This study examined an alternative, the Papadum test, designed for people with low levels of education/literacy.

The effect of source of supplemental dietary calcium and magnesium in the peripartum period, and level of dietary magnesium postpartum, on mineral status, performance, and energy metabolites in multiparous Holstein cows.

The objective of this study was to determine the effects of feeding different supplemental sources of Ca and Mg in the peripartum period, and different dietary levels of Mg postpartum, on plasma mineral status, performance, and aspects of energy metabolism in transition dairy cows. Multiparous Holstein cows (n = 41) were used in a completely randomized design with a 2 × 2 factorial arrangement of treatments starting at 28 d before expected parturition. Main effects were source assignments (CS = common sources of supplemental Ca and Mg, or MA = a blend of common and commercial mineral sources with supplemental minerals primarily from a commercial Ca-Mg dolomite source; MIN-AD, Papillon Agricultural Company Inc.

Effects of calcium magnesium carbonate and roughage level on feedlot performance, ruminal metabolism, and site and extent of digestion in steers fed high-grain diets.

A feedlot growth performance experiment and 2 metabolism experiments were conducted to evaluate dietary roughage concentration and calcium magnesium carbonate in steers fed a high-grain diet. In Exp. 1, one hundred ninety-two crossbred yearling steers (320 +/- 10 kg of initial BW) were fed diets based on steam-flaked corn with 0, 0.

Dyslexia and the learning of a foreign language in school: where are we going?

The difficulties which many dyslexic students encounter in the learning of the English language often extend to the learning of a foreign language in school. Although this problem has been acknowledged for some time, and although the learning of a modern foreign language is a core element in the Scottish curriculum, there has been little research into how modern languages can be presented to offer the best learning opportunities to dyslexic students. Dyslexic students are likely to benefit from a multisensory approach to the learning of a modern foreign language, and it seems likely that they will need to utilize similar strategies to those used for learning their first language.
