The effects of dietary energy source and feed withdrawal on muscle glycolytic potential (GP) and blood acid-base responses to handling were investigated in slaughter-weight pigs (initial BW 94.7 ± 1.01 kg). Crossbred pigs (n = 96; 48 barrows, 48 gilts) were used in a randomized complete block design with a 4 × 2 × 2 factorial arrangement of treatments: l) diet [control, high fat (10% supplement...

The process of nutrient transfer through an ecosystem is an important determinant of production, food-chain length, and species diversity. The general view is that the rate and efficiency of nutrient transfer up the food chain is constrained by herbivore-specific capacity to secure N-rich compounds for survival and production. Using feeding trials with artificial food, we show, however, that ph...

An experiment with 288 male (Ross 308) 1-d-old broilers was conducted to test the hypothesis that a coarse diet supplemented with butyric acid (BA) and fermentable carbohydrates (FC) improves performance of broilers with a poorly digestible protein source. The interaction effects of diet structure (fine or coarse), FC supplementation (with or without), and BA supplementation (with or without) i...

The experiment was conducted for a period of 75 days to study the effect of treatment of straw with urea or with urea and a urease containing chick pea seed meal and midden soil on chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, and feed conversion efficiency. For the study twelve indigenous growing bulls aged approximately 20 m...

two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

the aim of the present study was to determine the appropriate standardized ileal digestible lysine requirement to 49 day of olds in male but,6 turkey poults. experiment 1 and 2 were used  from 8-28 and 28-49 d-old respectively. one hundred sixty male but,6 turkeys in each experiment were used in a completely randomized design with eight treatments (8 levels of standardized ileal digestible lysi...

BACKGROUND An optimal valorization of plant biomasses to produce biofuels requires a good knowledge of the available contents and molecular composition of the main chemical components, which changes with the harvesting date. Therefore, we assessed the influence of harvesting date on the chemical characteristics of various energy crops in the context of their conversion to biofuels. RESULTS We...

Classical molecular dynamics is applied to the rotation of a dipolar molecular rotor mounted on a square grid and driven by rotating electric field E(nu) at T approximately 150 K. The rotor is a complex of Re with two substituted o-phenanthrolines, one positively and one negatively charged, attached to an axial position of Rh(2)(4+) in a [2]staffanedicarboxylate grid through 2-(3-cyanobicyclo[1...

Mortality after intravenous challenge with 10(4) Cryptococcus neoformans demonstrated that doubly immunodeficient beige athymic (bg/bg nu/nu) mice were more susceptible to systemic cryptococcosis than either bg/bg or nu/nu mice. Infected bg/bg nu/nu mice also had a shortened lifespan compared with their bg/bg nu/+ littermates. Beige athymic (bg/bg nu/nu) but not bg/bg nu/+mice developed cryptoc...

We have characterized the vibrational predissociation (VP) of the Ne(2)Br(2) van der Waals complex using time- and frequency-resolved pump-probe spectroscopy. After exciting Br(2) within the complex to a vibrational level 16<or=nu(')<or=23 in the B state, we follow the flow of halogen vibrational energy to the van der Waals modes in real time by recording the time-dependent behavior of Ne(2)Br(...
