The objective was to describe genetic parameters and genetic changes in litter sizes at birth and weaning (LB and LW, n =9081), birth weight (BW, n =11,896), weaning weight (WW, n =11,104), fleece weight and grade (FW and FG, n =8872), and staple length (SL, n =1805) of Polypay sheep. Direct heritability estimates from single-trait analyses were 0.11 for LB, 0.02 for LW, 0.17 for BW, 0.18 for W...

The purpose of this study was to investigate live weight (LW) and body condition (BC) variation in two lines of Rembi sheep reared in extensive and semi-intensive alimentary management. The heavy ewes of the first group were fed with 800g per head/day during winter and spring months. However, the light ewes of the second group received, in winter season, a survival diet regimen consisted of 300...

Electron trapping in a finite amplitude Langmuir wave (LW) leads to a frequency shift, ∆ωTP < 0 , and reduced Landau damping. These may lead to modulational instability. Its growth rate and damping threshold, due to escape of trapped electrons at rate ν, are calculated for the first time in the short wavelength regime. If the background plasma is in thermal equilibrium, it is shown that this tr...

The extent to which modifications in intermediary metabolism contribute to life history variation and trade-offs is an important but poorly understood aspect of life history evolution. Artificial selection was used to produce replicate genetic stocks of the wing-polymorphic cricket, Gryllus firmus, that were nearly pure-breeding for either the flight-capable (LW[f]) morph, which delays ovarian ...

[1] A 10 year record of Arctic cloud fraction and radiative forcing has been generated using data collected at the Atmospheric Radiation Measurement (ARM) North Slope of Alaska site and the nearby NOAA Barrow Observatory (BRW) from June 1998 to May 2008. The cloud fractions (CFs) derived from ARM radar‐lidar and ceilometer measurements increase significantly from March to May (0.57→0.84), remai...

BACKGROUND Skin collagen Long Wavelength Fluorescence (LWF) is widely used as a surrogate marker for accumulation of advanced glycation end-products. Here we determined the relationship of LWF with glycemia, skin fluorescence, and the progression of complications during EDIC in 216 participants from the DCCT. METHODS LW-1 and collagen-linked fluorescence (CLF) were measured by either High Per...

Reduced liverweight was used to evaluate the potential toxicity in mice of four naturally occurring steroidal glycoalkaloids: a-chaconine and a-solanine, ortomatine and solasonine. Increased liver weight was used to evaluate the three corresponding steroidal aglycones: solanidine, tomatidine, and solasodine and the non-alkaloid adrenal steroid dehydroepiandrosterone (DHEA). Adult female Swiss-W...

Improving feed efficiency in dairy cattle could result in more profitable and environmentally sustainable dairy production through lowering feed costs and emissions from dairy farming. In addition, beef production based on dairy herds generates fewer greenhouse gas emissions per unit of meat output than beef production from suckler cow systems. Different scenarios were used to assess the profit...
