Opis:
Immersed in the world dominated by pragmatism, contemporary man seems to be thinking and functioning only according to the criteria of effective acting. However, life experience, philosophical reflection, and the truth of Revelation lead to the conclusion that the laws of nature must be respected in the name of care for man and for one’s genuine good, even though they may, in certain cases, limit the effectiveness of acting and the possibility to acquire current profit. This article justifies the necessity to respect natural law in the sphere of transmission of  human life. The starting point of this scientific reflection is the theological vision of values and of the inviolability of human life on the basis of the description of creation from the Book of Genesis. The fundamental truths and moral norms are being neglected nowadays as—being so proud of modern technological achievements—man makes himself the creator and the master of human life. Although such activities seem impressive from the scientific point of view, they actually result in a number of serious contemporary and future threats. The second part of the article presents alarming aspects of  artificial interventions in the sphere of life transmission. By exposing the threats and by trying to prevent them in the sphere of infertility treatment, the Church opposes the methods of artificial insemination and becomes engaged in promoting naprotechnology which is a method that expresses genuine humanism, and which gives hope not only to the parents who want to have a baby but also to the mankind that longs for propitious future.

Opis:
Artificial Insemination (AI) in poultry production is a veritable technique in solving the problem of breeding and meeting the increasing demand. This study assesses the economics of artificial insemination in broiler production among sixty randomly selected broiler farmers in Nigeria. The analytical techniques employed include descriptive statistics, gross margin analysis, and stochastic frontier.  The result discovered that most of the farmers are male and are at their prime age. Majority of the livestock farmers have some form of formal education and a minimum of 5 (five) year experience in poultry farming. The capital was mostly sourced from the bank. Majority of the farmers has a stock size of more than 25,000 birds. They have a gross margin of N341, 933,406. Only 20% of gross income was used for operating expenses with a return on capital invested of 4.3. The mean technical efficiency was 80.70%. Feed, vaccine and stock size were statistically significant in determining efficiency while education and extension visits are the statistically significant variable influencing technical inefficiency. It is therefore recommended that affordable and accessible input, as well as training should be made available to farmers to achieve self-sufficiency and improve the economy.

Opis:
In this study, it was aimed to evaluate the reproductive performance of primiparous and nulliparous Saanen goats following the insemination made cervically via frozen commercial buck semen with short-time controlled internal drug release (CIDR, Eazi-Breed, Pfizer)-based synchronization. In the study, a total of 50 Saanen goats, 26 of which were aged 9 months and 24 of which were aged 2 years, were used. The CIDRs including 0.33 g of progesterone were applied to all the goats for 7 days and while the CIDRs were taken out of the vagina, the 500 IU equine chorionic gonadotropin (eCG) was injected intramuscularly. The first dose was administered in a fixed-time manner with mini straws of 0.25 ml including 300x106 motile frozen spermatozoa 24 hours after the injection without making estrus detection, and the second dose insemination was applied 24 hours later. In the study, although the pregnancy rate, fecundity, prolificacy and multiple birth rate values (83%, 1.25, 1.50 and 60%) obtained in the primiparous goats were found to be higher than those found in the nulliparous age group (80%, 0.84, 1.05 and 38%), they were not statistically significant. It was concluded that the effects of the CIDR-based double-dose insemination applications in the primiparous and nulliparous Saanen breed goats in breeding season for 7 days on fertility were similar and the cervical insemination method, a quick and more practical option compared to the intrauterine insemination, could be used successfully in both age groups.

Opis:
The study was conducted in the world multiple ovulation and embryo transfer technology in cattle. In animal husbandry application of artificial insemination, estrus synchronization, multiple ovulation and embryo transfer used for improving animal breeding and genetics. Embryo is an egg that has already been fertilized by a sperm cell. Embryo transfer is a process by which an embryo is collected from a donor female and then transferred in to a recipient female which serves as surrogate mothers for the reminder of pregnancy. The International Embryo Transfer Society data retrieval committee presents the embryo transfer activity participated countries was 39 and 50 in 2014 and 2015 respectively. There are two methods of production of embryos from donor females; in vivo and in vitro fertilization. The number of embryos collected by in‐vivo in 2015 was 660,221, this result highest of 614,464 recorded in 2014. The value is increased by 7.45% from this contribution of North America (64.66%), Europe (22.4%) and South America (11.09%). Embryos collected by in-vitro fertilization were recorded 592,450 and 671,161in 2014 and 2015 respectively. According to the data United States and Canada are the leading embryo exporter countries, each exporting over 10,000 bovine in-vivo embryos each year followed by Australia and Argentina. It is expected South America, Africa and some Asia countries export only limited amounts of embryos, mainly due to risk of transmission diseases. I recommended that care will be taken during selection of donor and recipients, transfer procedures of embryos as well as in recipient management will be needed to enhance the efficiency by reducing risk of transmitting genetic disease via embryo transfer and the member state will be recorded appropriate data and send to international embryo transferring society for compiled.

Opis:
Artificial reproductive technologies such as sperm and egg donation, in vitro fertilization, and surrogate motherhood all in principle separate the family from its biological foundation. These technologies enable and promote contemporary social trends that disconnect the family from its biological basis and claim that a family is constituted by an act of will, irrespective of biology. The article discusses three recent documentary films made by American Center for Bioethics and Culture, which consist of interviews with children born from sperm donation and women involved in egg donation and surrogate motherhood, to identify how the biological understanding of parenthood is undermined by these technologies and the ethical and anthropological consequences that follow. The author concludes that these technologies are also in principle available to single persons and to homosexuals to enable them to "have" children. He warns that potential and real deleterious effects of such behavior will be satisfying adults' whims by children.
Sztuczne technologie reprodukcyjne, np. dostarczanie spermy czy jajeczka, zapłodnienie in vitro i zastępcze macierzyństwo, oddalają rodzinę od jej biologicznych zadań. Techniki te umożliwiają i promują współczesne trendy społeczne, które prowadzą do oddzielenia rodziny od jej biologicznych podstaw. W związku z tym może wydawać się, że rodzina powstaje na mocy aktu woli dojrzałego człowieka, nieuwzględniającego biologii. Niniejszy artykuł rozważa trzy najnowsze filmy dokumentalne wykonane przez amerykańskie Centrum Bioetyki i Kultury, na które składają się wywiady z dziećmi zrodzonymi z ofiarowanej spermy oraz z kobietami, które dostarczały jaja i podjęły zastępcze macierzyństwo. Celem artykułu jest ukazanie, w jakim stopniu biologiczne po- jęcie rodzicielstwa jest podważane przez te technologie, a także zaprezentowanie ich etycznych oraz antropologicznych konsekwencji. Autor kończy swój wywód, zaznaczając, że wspomniane technologie umożliwiają także osobom wolnym i homoseksualistom „posiadanie" dzieci oraz ostrzegając, że potencjalnymi i rzeczywistymi zgubnymi skutkami takich zachowań będzie spełnianie przez dzieci zachcianek dorosłych.
