This article examines two interrelated animal welfare topics: the transportation of pregnant cattle, and the collection of fetal bovine serum (FBS). The occurrence of pregnant cattle at slaughter is unavoidable because of health, management, and economic reasons, or because farmers may be unaware of their pregnancy status. Since cattle are often sold to slaughterhouses through intermediaries, the pregnancy status of the cow is usually unknown until after it has been slaughtered and the uterus exposed. In slaughterhouses where fetal blood is collected, technicians are responsible for the detection and proper handling of fetuses, making sure they remain inside the uterus until dead, or are immediately euthanized. The harvesting of fetal blood also provides a possible source of information, which upon request, may help farmers improve the management of their livestock operations. The serum industry endorses the animal welfare standards set forth by the World Organization for Animal Health (OIE), as well as all existing local and national standards relating to the transportation of pregnant cattle and the collection of fetal blood. This article concludes that there is nothing negative or unethical about collecting blood from a dead fetus. Rather it would be unethical not to utilize available fetal tissues obtained from the slaughter of pregnant cattle, especially since FBS, used as an ingredient in cell culture media, contributes greatly to the advancement of the life sciences industry, as well as the replacement and reduction of live animals used in research and testing…

Growth performance testing in cell culture is an effective approach to making serum suitability and purchase decisions. An independent commercial testing lab conducted two separate and sequential growth promotion studies to underscore the need for pre-purchase lot performance testing with: (1) FBS; and (2) FBS alternatives. Results from both studies are presented here to compare and contrast:
• FBS lots to each other
• FBS alternatives lots to each other
• FBS alternatives lots to FBS
FBS alternatives are included because they are often overlooked as a cost-effective substitute for FBS, providing, in many cases, equivalent performance. It is advisable to avoid preconceived notions concerning the quality or performance of a serum product without considering the culture system, culture conditions, and the subject cells, which can all have a material impact on its performance in cell culture.
Test – then decide…
The continued use of animal serum as an important component in biotechnology manufacturing processes has raised questions regarding both the reliability of geographic origin and possible adulteration of product. The International Serum Industry Association (ISIA) has implemented a traceability certification program designed to demonstrate traceability from slaughterhouse or abattoir to the end-user. This is based on an audit performed by an independent, approved third-party auditor according to an approved audit plan, using a detailed audit checklist. Recent advances have led to the development of a complementary testing program to determine geographic origin of material. The methodology described in this paper differentiates fetal bovine serum from newborn calf serum on the basis of biochemical composition…
