Thirty-six multiparous Holstein cows were fed a mixture of corn silage and concentrate 1:1; dry matter (DM) basis and long hay (0.9 kg/d) through wk 18 of lactation. Beginning at 30 d prepartum ...through wk 4 of lactation, the total mixed rations of 18 of these cows were top-dressed daily with 10 g of Biomate Yeast Plus (Chr. Hansen's, Inc., Milwaukee, WI). The other 18 cows served as controls. At wk 5, both control and treated cows were divided into three groups and fed 0, 10, or 20 g/d of yeast. Yeast supplementation during early lactation significantly improved DM intake, milk yield, and the digestibility of crude protein and acid detergent fiber. Least squares means for DM intake, fat-corrected milk yield, crude protein digestibility, and acid detergent fiber digestibility for cows fed 0, 10, 20 g/d of yeast during wk 5 to 18 of lactation were 23.8, 24.7, and 25.0 kg/d; 37.7, 40.7, and 41.4 kg/d; 78.5, 80.8, and 79.5%; and 54.4, 60.2, and 56.8%, respectively. Although numerical responses in DM intake and milk yield were greater for cows fed 20 g/d of yeast than for cows fed 10 g/d of yeast, the response was not significant

Because of continuing concerns about the safety and the suitability of recycled newspaper as an animal bedding material, municipal curbside-collected newspaper was processed into chopped and pelleted ...forms for comparison studies with wheat straw and kiln-dried pinewood shavings. Measurements included nutrient, heavy metal, dioxin and furan content, particle size distribution, density, combustion potential, and water-holding capacity. Recycled newspaper, straw, and wood shavings tested below or equivalent to National Research Council dietary tolerance levels and US Environmental Protection Agency toxic equivalent levels. Small particle size distribution was shavings > straw > all forms of newspaper. The density of pelleted newspaper was 50-fold greater than that of chopped newspaper and straw and 15-fold greater than shavings. In simulated flash burns, chopped newspaper, straw, and shavings ignited, and flames spread rapidly in newspaper and shavings and lasted the longest in shavings. Pelleted newspaper did not ignite. Chopped and pelleted forms of newspaper and wood shavings had higher water holding capacities (>400%) than did straw (200%). Animal industries can, in confidence, utilize recycled newspaper as an animal bedding material, providing that sources of low toxicity are identified, and suitable processed forms are produced.
This paper presents the design of a system that supports execution of HLA (high level architecture) distributed interactive simulations in an unreliable grid environment. The design of the ...architecture is based on the OGSA (Open Grid Services Architecture) concept that allows for modularity and compatibility with grid services already being developed. First of all, we focus on the part of the system which is responsible for migration of a HLA-connected component or components of the distributed application in the grid environment. We present a runtime support library for easily plugging HLA simulations into the grid services framework. We also present the impact of execution management (namely migration) on overall system performance.
A new large population of the Asian clam
(O. F. Müller, 1774) was found within a reach (ca 210 km long) of one of the largest European rivers, the Vistula. The largest population and the largest ...individuals were found at the outlet of a channel collecting heated water from the cooling process at the Połaniec power station and adjacent parts of the river. In the northern part of the study area, bivalves occurred at the channel margins, in groyne fields, and in the shallows of sand banks or sandbars. The clams were less numerous in places where the river was regulated with straightened banks and stone ripraps. Twenty-five other taxa of mollusks were found altogether at the sampling stations where
was observed, including other non-indigenous mollusk species.
The blowfly Lucilia bufonivora shows high host specificity for toads despite the host’s toxic skin secretion, which consists mainly of bufadienolides. These toxins are effective blockers of the Na⁺, ...K⁺-ATPase, an enzyme that is essential for many physiological processes in animals. Whereas common toad (Bufo bufo) toxins were identified in the larvae of the fly, few toxins were found in the pupae and empty puparia as trace amounts, while adult flies were entirely free of these toxic compounds. Similar results were obtained when larvae of generalist necrophagous blowflies (L. sericata, Calliphora vicina) fed on toad carcasses. Analysis of the Na⁺, K⁺-ATPase gene revealed no amino acid substitution at positions known to mediate resistance to bufadienolides in other systems. Alternative mechanisms of resistance such as efficient excretion of the compounds may enable the flies to use this poisonous food source.
The habitat requirements of swan mussel Anodonta cygnea L. were studied in water bodies on the floodplain of the Nida river (Southern Poland). Swan mussel showed preferences neither for the ...geomorphologic types of water bodies nor for natural vs. anthropogenic site origin. It occurred more frequently in wide ponds, with less complicated bank line. Traits of water bodies that were linked with presence of swan mussel correlated also with concentration of dissolved oxygen. Swan mussel avoided silted water bodies and those with high proportion of surface overgrown with floating vegetation. It showed co-occurrence with plants from genus Ceratophyllum L. and Hydrocharis L. It was concluded that preference of the species for larger water bodies, of simpler shape and at early successional stages was related to high oxygen demand in this species. The functioning of natural river valley versus regulated river were discussed in relation to occurrence of large mussel species
