abstract  background: low birth weight neonates are confronted with some problems after  birth, they should be followed up and evaluated at different ages of life.the aim of this study was to determine the impact of birth weight on the risk of sensorineural hearing impairment on children.  method: this cross sectional and retrospective study determined the prevalence  of hearing problems in low...

The objective of this study was to determine the genetic parameters of methane (CH4) emissions and their genetic correlations with key production traits. The trial measured the CH4 emissions, at 5-min intervals, from 1225 sheep placed in respiration chambers for 2 days, with repeat measurements 2 weeks later for another 2 days. They were fed in the chambers, based on live weight, a pelleted luc...

The developments in Norwegian sheep breeding since the early 1990s are reviewed. For the largest breeding population, the Norwegian White Sheep, results are presented for both genetic and phenotypic changes. Of the nine traits that make up the aggregate genotype, the largest gain per year, in per cent of the corresponding phenotypic average, was found for carcass grade (1.66%) and carcass weigh...

Anthropometric parameters are an important indicator of health and nutritional status comprising the whole span of mans life. However, they are not of the same degree of simplicity and sensitivity in assessing the public health status. During recent decades many studies have attempted to examine the relationships of these measurements in order to present simple alternatives for similar purposes...

The production performance of ewes was assessed in a terminal crossbreeding experiment involving five Merino and Merino-type dam lines and two terminal crossbreeding sire breeds. Dam lines were SA Mutton Merino (SAMM), SAMM rams crossed to Merino ewes (SAMM cross), Dohne Merino, as well as specialist Merino lines selected for clean fleece weight (FW+) and for an increased reproduction (Rep+). D...

background: given the importance of birth weight and the effects of anthropometric indices and socioeconomic status on it, this study was conducted to assess birth weight and its related factors among infants born in the hospitals of ahwaz jondishapour university. methods: this cross-sectional study was carried out on 269 newly born babies and their mothers in hospitals of ahwaz jondishapour un...

background: low birth weight (lbw or birth weight <2500 g) is one of the most serious health problems in today's world. objective: the purpose of this study was to evaluate growth parameters of neonatal intensive care unit (nicu) admitted lbw preterm neonates at corrected ages of 6 and 12 months. materials and methods: in a prospective cohort (follow up) study, all lbw preterm neonates whom wer...

a pedigree file consisting of 5860 individuals, 167 sires and 1582 dams collected at makooei sheep breeding station (msbs) during a period of 24 years (1990 to 2013) was used to calculate the inbreeding coefficients to reveal any probable effects of inbreeding (f) on the studied traits. the studied traits were classified to the five main groups including body weight, kleiber ratio, body measure...

conclusions: the increased survival of preterm infants was not associated with lower complications. there is now increasing evidence of sustained adverse outcomes into school age and adolescence, for preterm infants. results: cerebral palsy especially spastic diplegia, intellectual disability, visual (retinopathy of prematurity) and hearing impairments are the main neurodevelopmental disorders ...
