To predict the effects of global change on marine populations, it is important to measure the effects of climate stressors on performance and potential for adaptation. Adaptation depends on heritable genetic variance for stress tolerance being present in populations. We determined the effects of near-future ocean conditions on fertilization success of the sea urchin Pseudoboletia indiana. In 16...

PURPOSE To investigate the effect of folic acid (FA) in an experimental model of anorectal malformations (ARMs) ethylenethiourea (ETU) induced. METHODS Eight female Wistar rats were divided randomly in two groups. Group A - ETU; Group B - FA+ETU; Dams from group B received daily, since two weeks before pregnancy to the end of pregnancy, FA (50mg/kg) by gavage. Dams from groups A and B, receiv...

Seven years after the introduction of genomic selection in the United States, it is now possible to evaluate the impact of this technology on the population. Selection differential(s) (SD) and generation interval(s) (GI) were characterized in a four-path selection model that included sire(s) of bulls (SB), sire(s) of cows (SC), dam(s) of bulls (DB), and dam(s) of cows (DC). Changes in SD over t...

Pedigree information which collected from 1979 to 2012 were used to study the genetic variability and population structure of Raeini Cashmere goat, taking kids born from 2009 to 2012 into account as reference population. Averages of inbreeding coefficients in whole and inbred populations were computed to be 0.04% and 4.41%, respectively. Considering the reference population, average inbreeding ...

Angus (A), Brown Swiss (S) and A X S reciprocal F t (AS) dams were mated to A, S and AS (also reciprocal F 1 ) sires resulting in nine breed groups of progeny with varying proportions of Angus and Brown Swiss breeding. Breed group of dam and of sire significantly influenced birth weight, preweaning daily gain, weaning weight, 205-d weight, condition score and frame size. The means for birth wei...

The fresh water reservoirs are one of the main power resources of Pakistan. These water reservoirs are in the form of Tarbela Dam, Mangla Dam, Bhasha Dam, Warsak Dam etc.[1]. To estimate the current power capability of the Dams, the statistical information about the water in the dam has to be clear. For the purpose of water management monthly or yearly survey of the dams required. One of the im...

In its final report, published in November 2000, the World Commission on Dams concluded that the benefits derived from large dams have made a significant contribution to human development. However, in many cases the environmental and social costs have been unnecessary and, by present standards, unacceptable. Often negative impacts arise as a consequence of lack of foresight and because dams are...

Recent publications indicate that the prevalence of perinatal mortality has increased in some dairy industries and an increased proportion of this loss is not associated with the traditional risk factors for perinatal mortality. The objectives of this study were to establish the prevalence of perinatal mortality (calf death within 24 h of calving) in Irish dairy herds and to determine the curre...
