Invited review: effects of milk ration on solid feed intake, weaning, and performance in dairy heifers.
It is concluded that milk-fed dairy calves can safely ingest milk at approximately 20% of body weight (BW/d), and greater milk consumption supports greater BW gain, improved feed efficiency, reduced incidence of disease, and greater opportunity to express natural behaviors, which in combination suggest improved welfare.
Hay intake improves performance and rumen development of calves fed higher quantities of milk.
Research to date has suggested that access to forage before weaning can limit rumen development in calves, but no research has yet addressed the role of forage for calves fed higher quantities of…
Structural growth, rumen development, and metabolic and immune responses of Holstein male calves fed milk through step-down and conventional methods.
Greater feed consumption, BW gain, and structural growth, and a more metabolically and physically developed rumen were observed in calves on the STEP method than in those on the conventional method.
The effect of salinity on the growth, water status, and ion content of a leaf succulent perennial halophyte, Suaeda fruticosa (L.) Forssk
Water potential and osmotic potential of plants became more negative with an increase in salinity and Gibberellic acid and kinetin alleviated some of the inhibitory effects of salinity on shoot growth of S. fruticosa while root growth was promoted by Kinetin.

It is concluded that the provision of high-starch and low-fiber starter feeds may negatively affect rumen development and that forage supplementation is beneficial for promoting development of the gut and rumination behavior in young calves.
Effects of Salinity on Growth, Water Relations and Ion Accumulation of the Subtropical Perennial Halophyte, Atriplex griffithii var. stocksii
Atriplex griffithii accumulated a large quantity of ions, with the ash content reaching 39% of the dry weight in leaves, which is significant in osmotic adjustment and facilitates water uptake along a soil-plant gradient.
Hydrothermal time as a tool in comparative germination studies.
The results illustrate that germination rate in water or at reduced water potentials is closely associated with HTT parameters, which have important ecological relevance, in that they help explain differences in germination patterns associated with contrasting habitats.
Salinity tolerance in some mangrove species from Pakistan
All mangrove species showed optimal growth at 50% seawater and tissue water potential became more negative with the increase in salinity and stomatal conductance was decreased in all plants.
