Animal Biotechnology: Science-Based Concerns by Debra Davis

By Debra Davis

Genetic-based animal biotechnology has produced new nutrition and pharmaceutical items and provides many extra advances to profit humankind. those interesting customers are observed by way of substantial unease, despite the fact that, approximately issues corresponding to defense and ethics. This publication identifies science-based and policy-related issues approximately animal biotechnology - key concerns that needs to be resolved sooner than the hot breakthroughs can achieve their strength. The ebook incorporates a brief background of the sector and offers comprehensible definitions of phrases like cloning. taking a look at applied sciences at the close to horizon, the authors talk about what we all know and what we worry approximately their results - the inadvertent liberate of harmful microorganisms, the security of goods derived from biotechnology, the effect of genetically engineered animals on their setting. as well as those issues, the publication explores animal welfare issues, and our societal and institutional potential to control and keep watch over the expertise and its items. This available quantity might be vital to everybody attracted to the consequences of using animal biotechnology.

The product quality of reproductively sterile, triploid oysters remains high year-round. Hence, triploid stocks of Pacific oyster (Crassostrea gigas) provide a tangible benefit to aquaculturists, and now make up almost half of commercial production in the Pacific Northwest. Unfortunately, repeatable induction of 100 percent triploidy on a commercial scale poses a considerable technical challenge. Non-triploid larvae within batches of larvae easily can go undetected if their frequency is low (USDA, 1995).

Genetically engineered poultry, swine, goats, cattle, and other livestock also are beginning to be used as generators of pharmaceutical and other products, potential sources for replacement organs for humans, and models for human disease. The technology to produce foreign proteins in milk by expressing novel genes in the mammary glands of livestock already has advanced beyond the experimental stage, with some of the products currently in clinical trials (Colman, 1996; Murray and Maga, 1999). In theory, transgenic animals can provide milk that is more nutritious for the consumer, or that is enhanced for certain protein components that might be valuable for INTRODUCTION 17 manufacturing cheese or other dairy products.

Although the committee’s charge is limited to addressing science-based concerns, the committee notes that (1) socially, politically, and ethically determined factors influence both the nature of scientific research and the interpretation of data, (2) how one addresses scientific uncertainty or the importance of various concerns that result from introduction of a proposed technology is influenced by political and ethical considerations, and (3) technologies often have impacts on social, political, economic, religious, and spiritual conditions or values which, in turn, might impact health and the environment.
