The residual activities of transgenic corn-derived and 2 commercial microbial phytases (PA and PB) along the gastrointestinal tract (GIT) of laying hens were compared to evaluate their relative resistance to hydrolysis in the GIT when added to P-deficient diets. The treatments consisted of a negative control (NC) diet containing 0.10 nonphytate P and an NC diet supplemented with transgenic corn...

The incidence of cerebral lesions in stroke-prone spontaneously hypertensive rats appears to depend on the severity of the hypertension and nutritional factors. Comparison of American and Japanese commercial rat diets revealed a much higher incidence of stroke in rats receiving the Japanese diet (88% vs 30% by 9 months of age). Analyses of the diets indicate that perhaps the most important diff...

In recent years~ severaL species of crab have come under increasing study by scientists. Fluctuations in populations of important commercial species (the blue crab) and the commercial potential of others (the rock crab and deep sea red crab) have led t o this increased attention. But in lab situations, researchers have had problems keeping their specimens alive and healthy for long periods. It ...

An experiment using 336 Hy-Line W-36 Single Comb White Leghorn hens was conducted to evaluate transgenic soybeans containing the gm-fad2-1 gene fragment and the gm-hra gene. Transcription of the gm-fad2-1 gene fragment results in an increased level of oleic acid (18:1) in the seed, and expression of the soybean acetolactate synthase protein (GM-HRA) encoded by the modified gm-hra gene, is used ...

Development of nymphs and oocyte maturation in adults were examined in Blattella germanica (L.) reared on three commercial diets. Nymphs fed rat food developed significantly faster than nymphs fed two commercial dog foods. Similarly, oocytes matured more quickly in adult females that were raised on rat food than in females raised on dog food. Nymphal development and oocyte maturation were slowe...

The effect of diatoms of the genus Cocconeis on the sex reversal of the shrimp Hippolyte inermis Leach was examined in the laboratory. Randomised experiments were carried out to investigate the functional response of shrimps to various diets. The benthic diatom Cocconeis neothumensis was offered, alternatively, during the larval phase and during the postlarval phase, and the results obtained wi...

Two experiments utilizing a total of 530 pigs were conducted to evaluate the effects of commercial enzymes in diets containing dried distillers grains with solubles (DDGS) on nursery pig growth performance. In Exp. 1, 180 pigs (initially 19.9 lb) were used in a 27-d growth trial to compare the effects of Easyzyme, Hemicell-W, and Porzyme in diets containing 30% DDGS on weanling pig performance....

The energy value of NSP has been expressed as their metabolizable energy (ME) content. The aim of the present study was to determine whether differences in ME and net energy (NE) contents were similar for insoluble and soluble NSP. Nine healthy young men were offered three diets according to a Latin-square design (3 x 3) with three repetitions: diet C (control), diet B (control + 50 g sugarbeet...

FRESH and dried bitter (high HCN) cassava, sweet (low cassava a commercial pellet diet were fed to rats during two life-cycles. First litter birth weights of on fresh Cassava diets significantly (P<0.05) lower than other diets. Performance sun probably more affected by the fungal growth sundried chips, rather influence its hydrocyanic acid content. Histopathological examination thyroid tissu...
