A 5-yr study involving 45 to 78 pregnant Hereford range cows each year evaluated relationships among prepartum nutrition, body condition scores, BW changes and reproductive performance. Four prepartum nutritional treatments were imposed. One group of cows were fed to maintain (M) their November BW until calving in March and April. The other three groups of cows were fed to lose about 5% of thei...

D IFFERENCES in type (mutton conformation) and condition (degree of fatness) are generally considered to be responsible for differences in the price per pound when range lambs are sold on the market. Since these traits are most evident when the first culling of lambs occurs soon after weaning, it seems probable that they receive considerable emphasis in most sheep breeding enterprises. Despite ...

We investigate unbounded continuous spin-systems with infinite-range interactions. We develop a new technique for deducing decay of correlations from a uniform Poincaré inequality based on a directional Poincaré inequality, which we derive through an averaging procedure. We show that this decay of correlations is equivalent to the Dobrushin-Shlosman mixing condition. With this, we also state an...

We show that a suitable weak solution to the incompressible Navier–Stokes equations on R3×(?1,1) is regular R3×(?1,0] if ?3u belongs M2p/(2p?3),?((?1,0);Lp(R3)) for any ?>1 and p?(3/2,?), which logarithmic-type variation of Morrey space in time. For each this is, up logarithm, critical with respect scaling equations, contains all spaces Lq((?1,0);Lp(R3)) are subcritical, 2/q+3/p<2.

Grazing changes plant species composition of grassland ecosystems by selective removal and trampling. Grazing also alters soil physical and biogeochemical properties and can dramatically change hydrologic processes that can impact water budgets and quality. For these reasons, practical means are needed to assess grazing management practices and its impacts upon the land. This study examines whe...
