Estimation of genetic parameters for birth weight, preweaning mortality, and hot carcass weight of crossbred pigs.
Genetic parameters for birth weight (BWT), preweaning mortality (PWM), and HCW were estimated for a crossbred pig population to determine if BWT could be used as an early predictor for later performances. Sire genetic effects for those traits were estimated to determine if early selection of purebred sires used in crossbreeding could be improved. Data were recorded from 1 commercial farm betwee...
متن کاملMaternal Periodontal Disease as a Potential Risk Factor for Preterm Birth and Low Birth Weight
Background and Aim: Periodontal disease may cause adverse pregnancy outcomes such as low birth weight (LBW) or preterm birth (PTB). In the present study, mothers with one of these two delivery complications were analyzed regarding presence/absence of periodontal disease as a possible risk factor in comparison with related medical risk factors. Materials and Methods: In this cross-sectiona...
متن کاملNEONATAL MORTALITY IN RELATION TO BIRTH WEIGHT
730 low birth weight (LBW) neonates and 1460 controls were selected from 13,123 neonates born from October 1988 to June 1989 in 17 hospitals and maternity units in Tehran, and were compared for mortality in the first seven and up to 28 days of life (early neonatal period). In this study all low birth weight newborns are divided according to four sub-groups of birth weight, and the mortalit...
متن کاملrisk factors for neonatal mortality among very low birth weight neonates.
the objective of this study is to determine risk factors causing increase in very low birth way (vlbw) neonatal mortality. the medical files of all neonates weighing ≤1500 g, born in vali-e-asr hospital (2001-2004) were studied. two groups of neonates (living and dead) were compared up to the time of hospital discharge or death. a total of 317 neonates were enrolled. a meaningful relationship e...
متن کاملconditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market
ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
