controversy that many people are unaware of is gestational stalls in swine protection. “A gestation crate is a steel crate that is approximately seven feet long and two feet wide” (Bob Segall). Gestation stalls are used for only pregnant sows before they give birth. The sows have their own food and water, which protects them from fighting over food. This is where the controversy begins, some say that “gestation crate is the definition of animal cruelty” and that the pork industry needs to…

you may be wondering when would be the right time conduct a prenatal DNA test, or if it even matters when you choose to have the test. What is the timeline for performing prenatal DNA testing? Each prenatal diagnostic test requires a different gestation period for testing. The test you choose will most likely depend on the genetic disorder for which your baby is at risk. First Trimester CVS, or Chorionic Villus Sampling, is an invasive procedure used to diagnose Down syndrome, edwards…

was 2 years. The most of them primigravid, housekeeper and educated eight years (middle school). At the time of the interview, the gestational age of two women was under 14 weeks, four women were between 14 and 28 weeks of gestation, nine women were higher than 28 weeks of gestation and five women were in the postnatal period (maximum of one week after delivery). The mean score of participants' spouse age was 25 years. All spouses were self-employee and the most of them were educated up to 12…

the left and right hemispheres which occurs sometime between the 18th and 28th day of gestation. The primary defect is the lack of forebrain tissue which is impacted by a lack of sonic hedgehog signaling which causes the facial defects. During the 4th week of gestation, the neural tube gives rise to the three primary brain vesicles prosencephalon, mesencephalon, and rhombencephalon. In the 5th week of gestation, the prosencephalon divides into the telencephalon and…

the obstetrical dilemma and findings that support the energetics of gestation and growth hypothesis. At the beginning, the article systematically goes through each supporting piece of evidence for the obstetrical dilemma and provides findings that suggest the evidence is not valid. Ideas that are evaluated are that human gestation is shorter than needed, human fetuses receive less maternal investment than expected during gestation, and that walking upright efficiently requires narrow pelvises…

maternal stimulus, nutrition is the most important due to direct and indirect effects on the different stages of development. It was determined by Baker et al. (1994) that if maternal undernutrition was present in the first half of gestation and corrected mid gestation the offspring would have a normal body weight but experience health problems. After Baker presented this data…

regulating adrenocortical growth and steroidogenesis within sheep fetus that is in late gestation period. The researchers observed a significant rise in the levels of ACTH 1-39 in the plasma between 120-125 and 136-142 days, but did not observe any change after the fetal hypothalamus and pituitary were surgically disconnected at 106-120 days of the gestation period. The results did not show the effect of both HPD and gestation age on the circulating concentrations of pro-ACTH and ACTH-containing…

Hematotrophic phase: After third week of gestation, substances are transported passively via intervillous space. (Anju et al., 2011) Growth rate: Growth rate of fetus is linear up to 37 weeks of gestation, after which it plateaus (Anju et al., 2011). A slow growth rate and preterm labor can cause a low birth weight. Low birth weight (below 2000 grams) can increase…

in almost everyone’s daily life, whether you are a farmer benefiting from their production to live or you are a dairy product consumer. In this essay, we will see some important aspects concerning dairy cow reproduction; before, during and after gestation. Whether by natural means or artificial insemination, it is primordial for the farmer to know when and how long the cow has been in estrus to plan the pregnancies and calving’s. There are many different methods of detecting estrus in cows. The…
