A series of simulations were performed to evaluate the effects of mature size (WMA; 60, 70, 80 and 90 kg), slaughter weight (SW; 55, 60 and 65 kg) and three diets fed to feedlot lambs. Rations included a traditional diet (C2L) or placing weaned lambs on alfalfa for either 30 (A30) or 60 (A60) d before placing them on the C2L diet (A30-C2L and A60-C2L). Two lamb pricing schemes were used in the ...

the price volatility spillover effect indicates that price volatility in different markets can be mutually affected. the objective of the study is to analyze volatility price spillover effects on the vertical levels including input, wholesale and retail sale levels in the tehran beef supply chain. the multivariate generalized autoregressive conditional heteroskedastic (mvgarch) model was used b...

A single daily oral dose of polyethylene glycol (PEG) Ð a tannin-binding agent Ð has been shown to substantially improve feed intake and ef®ciency of utilization by sheep and goats consuming tannin-rich forage. The aim of this study was to quantify the effect of supplementing 10 g/day of PEG on the performance of does grazing on Mediterranean woodland and scrubland. The experiments were carried...

this research develops a two-level model based on hypotheses, which concern relationships among role ambiguity, role conflict, job involvement and salesperson performance at individual level and collective sale self efficacy, customer orientation and competitive climate at sale unit level in iranian food industry. data was drawn from 482 sales people in 30 companies , using a 51-item self-repor...

Measurement invariance is an important assumption to meaningfully compare children's quality of life (QoL) between different raters (eg, children and parents) and across genders. Moreover, QoL instruments may combine using negatively and positively worded items-a common method to reduce response bias. However, the wording effects may have different levels of impact on different raters and gende...

Variation in the number, total weight, mean individual weight and minimum individual weight of live pups at first and second litter were studied in hemiovariectomized (H = 54 does) and normal (N = 55 does) rabbit does. The total number of implanted embryos in 25 unoperated (N) and 54 hemiovariectomized (H) does were recorded by laparoscopy on the 12th day of their second pregnancy. The total nu...

this experiment was conducted to determine the chemical composition and gross energy of poultry by product meal (pbpm) and the effects of different levels of inclusion of poultry by product meal on broiler chicken performance, serum uric acid and carcass characteristics. three samples of pbpm produced in ardabil province located in northwest of iran, were provided during one month sampling peri...

six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. the chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. each treatment had 150 bir...

We have performed a 4-μs molecular dynamics simulation to investigate the native conformational preferences of the intrinsically disordered kinase-inducible domain (KID) of the transcription factor CREB in solution. There is solid experimental evidence showing that KID does not possess a bound-like structure in solution; however, it has been proposed that coil-to-helix transitions upon binding ...

The genetic traits of a purebred bull convey the reproductive and economic value to buyers. This study examines and compares the value of actual production weights (birth, weaning, and yearling weight), production expected progeny differences (EPDs) (birth, weaning, milk, and yearling), and ultrasound EPDs (carcass quality predictors) for purebred Angus bulls sold at auction. One EPD, birth wei...
