“…The potential negative influence of transgenesis on the health and welfare of farm animals is an important issue in genetic engineering studies (Van Reenen et al, 2001;Greger, 2011). Tang et al (2011) evaluated the effects of the expression of fat-1 genes on the health status of pigs and on the safety of the environment from the angle of changes in the intestinal population of microbial flora.…”

The health-promoting properties of dietary long-chain n-3 polyunsaturated fatty acids (n-3 LCPUFAs) for humans are well-known. Products of animal-origin enriched with n-3 LCPUFAs can be a good example of functional food, that is food that besides traditionally understood nutritional value may have a beneficial influence on the metabolism and health of consumers, thus reducing the risk of various lifestyle diseases such as atherosclerosis and coronary artery disease. The traditional method of enriching meat, milk or eggs with n-3 LCPUFA is the manipulation of the composition of animal diets. Huge progress in the development of genetic engineering techniques, for example transgenesis, has enabled the generation of many kinds of genetically modified animals. In recent years, one of the aims of animal transgenesis has been the modification of the lipid composition of meat and milk in order to improve the dietetic value of animal-origin products. This article reviews and discusses the data in the literature concerning studies where techniques of genetic engineering were used to create animal-origin products modified to contain health-promoting lipids. These studies are still at the laboratory stage, but their results have demonstrated that the transgenesis of pigs, cows, goats and fishes can be used in the future as efficient methods of production of healthy animal-origin food of high dietetic value. However, due to high costs and a low level of public acceptance, the introduction of this technology to commercial animal production and markets seems to be a distant prospect.

“…In the last 20 years, many kinds of transgenic species have been produced for agriculture and medicine application [10]. For example, the transgenic technology in beef cattle industry may improve animals for faster growth, higher quality beef products, or disease resistance [11][12][13].…”

The modern animal biotechnologies, such as animal cloning, transgenesis, sex determination, stem cells, designing new livestock, must be performed on animal gametes including sperm and oocytes, and embryos based on embryology theory. Currently, some key biotechnologies in embryology have become the most powerful tool for animal scientists and breeders to improve genetic construction of animal herds. Here, authors put forward a new concept of Animal Embryo Breeding Science to describe this discipline formation, development, and application in animal genetic improvement and breeding. The relationship of embryo breeding with other disciplines has been profiled. Thus, animal scientists and breeders can easily understand and apply embryo breeding theory and related key techniques to accelerate animal improvement speed, to modify genetic construction of animal population, and to design and create new animal individual or breed.

“…Tyrda et al, [17] The aim was to compare the thyroid tissue structures of transgenic rabbits that express human coagulation factor VIII and compare it to non-transgenic rabbits. The analysis did not reveal significant differences (P> 0,05) related to the volume of the basic thyroid structures and in the measurement of the height of the epithelium and nuclear diameter of the follicular cells.…”

How to cite: Alba, A.; et al, Research panorama on the second green revolution in the world and Colombia, TECCIENCIA, Vol. 8 No. 15., 49-64, 2013 AbstractThe second Green Revolution is understood as the development of transgenic varieties, using tools such as genetic engineering and molecular biology applied to the DNA molecule. The product of the second Green Revolution corresponds to genetically modified organisms (GMOs) developed from inter-species cross manipulation and genetic information of some species of interest. The second Green Revolution was established as a strategy to help ensure food security, an increasingly growing population, and demanding of resources, to optimize crop productivity improving or introducing specific characteristics such as resistance to insects and herbicide tolerance to allow GMOs to be more tolerant of natural aggression. The debate on this revolution is maintained, sharpening and raising many interests due to its transversal aspects and impact on social, scientific, economic, political, and ecological issues. This paper aims to review the history, development, and applications of the second Green Revolution framed within the advantages and disadvantages of the environmental components that interact on the soil. Due to the impact of the techniques used by the second Green Revolution and the various complex interactions among different environmental components, this paper provides a panoramic description open to discussion and research in soil science and landscape ecology, leading the precise determination of the conditions generated in the natural and human environment. To conclude, a SWOT analysis is made available of transgenesis in environmental components.Keywords: Biotechnology, Biodiversity, Soil Science, Landscape Ecology, Green Revolution, Transgenesis, Genetically Modified Organisms ResumenLa segunda revolución verde se entiende como el desarrollo de variedades transgénicas utilizando herramientas como la ingeniería genética y la biología molecular aplicadas a la molécula de ADN. El producto de la segunda revolución verde son los Organismos Genéticamente Modificados (OGM) desarrollados a partir de la manipulación y cruce interespecífico de la información genética de algunas especies de interés. La segunda revolución verde se estableció como una estrategia para ayudar a garantizar la seguridad alimentaria de una población cada vez más creciente y demandante de recursos, teniendo como propósito optimizar la productividad de los cultivos mejorando o introduciendo características específicas como la resistencia a insectos y tolerancia a herbicidas que permitan a los OGM ser más tolerantes a las agresiones del medio natural. El debate sobre esta revolución se mantiene, se agudiza y 50 suscita muchos intereses debido a su transversalidad e impacto en aspectos de orden social, científico, económico, político y ecológico. En este documento se pretende revisar los antecedentes, desarrollo y aplicaciones de la segunda revolución verde enmarcados en las ventajas y desventaja...
