Although direct manipulation (DM) has been considered a potentially inappropriate interface style for learnware, convincing indication that the problem with DM lies rather on “what is manipulated” than on the “manipulation” itself has been obtained from empirical studies in the domain of Euclidean geometry. A semiotic examination of such findings suggests that there may be theoretically-based c...

metabolizable protein (mp) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (rup) sources. effects on production efficiency and n utilization of early post-partum dairy cows were determined. forty-two multiparous and 16 primiparous holstein cows were assigned to the diets in a randomized complete block design immediately after part...

The objective of this study was to determine how harvest maturity of whole-crop cereals commonly used in swath grazing systems in western Canada affects yield, chemical composition, and in situ digestibility. We hypothesized that the increase in yield with advancing maturity would not offset the decline in digestibility and, thus, the yield of effectively degradable DM (EDDM) would decline with...

The objective of the present study was to characterize maize silage according chemical composition, yield, as well their predicted milk production. A search made on studies related density, composition (DM, CP, NDF, starch), and dry matter digestibility (DMD). In this study, 41 varieties from temperate regions 101 tropical origin were analyzed. net energy lactation (NEL Mcal/kg DM), kilograms p...

of the two diseases, treatment of persons with dual disease and prevention of TB in persons with DM.5 For each of these challenges, the knowledge gaps are highlighted along with the research questions that need to be answered if care and control of the dual burden of disease are to be achieved. The second review article looks at existing and new technologies for screening and diagnosing type 2 ...

The objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass Agropyron elongatum. A split plot design was conducted using a complete randomized block with two replications in Lorestan (Borujerd), Iran during 2007-2008. The genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...

Sixteen Holstein cows in midlactation were used in a 4 x 4 Latin square design to determine the effect of replacing alfalfa NDF with NDF from whole, linted cottonseed or dried distillers grains. Low and high fiber control diets (13 and 19% of dietary DM from alfalfa haylage NDF, respectively) were compared with diets designed to contain 13% of DM from alfalfa haylage NDF plus 6% of DM from eith...

This study describes milk production and milk composition of Iberian red deer (Cervus elaphus hispanicus) females (hinds) and the effect of calving date and BW change of hinds by milking over 34 wk. All hinds produced milk throughout the 34-wk study period, well over the standard lactation period. Total milk yield was 224.1 +/- 21.1 L, and daily production was 0.91 +/- 0.06 L. Milk yield decrea...

in order to investigate the effects of super absorbent polymer application on reduction of drought stress to corn, a split plot arrangement based on randomized complete block design with three replications was conducted at research field of agriculture faculty of ferdowsi university of mashhad during growing season of 2010-11. the main plot treatments were 1) application of 40 kg.ha-1 super abs...

Thirty lactating Holstein Friesian cows were used in a three treatment randomised block design experiment to investigate the influence of degree of grass wilting prior to ensiling on animal performance and energy utilisation. The three forage treatments were produced from perennial ryegrass swards either ensiled directly or mown, conditioned, spread and tedded to ensure rapid wilting, and ensil...
