Genetic modification has been used to create dairy cattle without horns and with increased resistance to disease; applications that could be beneficial for animal welfare, farm profits, and worker safety.

Nontransgenic Molecular Methods of Manipulation. Genetic features can be added to plants and animals without inserting them into the recipient organism's native genome. DNA of interest may be delivered to a plant cell, expressing a new protein—and thereby a new trait—without becoming integrated into the host-cell DNA.

metabolism of the dairy cow to produce milk with higher protein content, which might increase cheese production per unit of milk as well as fluid consumption per capita. This paper will be limited to the impact of genetic manipulation of the reproductive process in …

2022年5月1日 · Major steps in the development and implementation of targeted reproductive management programs for dairy cattle include identification and validation of robust predictors of reproductive outcomes and cow performance, and the development and on-farm evaluation of reproductive management strategies for optimizing outcomes of interest for subgroups...

2018年1月1日 · In this review, we discuss applications of both classical genetic modifications (GM) using vectors and genome editing in dairy cattle breeding. We use an interdisciplinary approach considering both ethical and animal breeding perspectives.

Predictors of cow performance currently explored for use in targeted management include genomic predictions; behavioral, physiological, and performance parameters monitored by sensor technologies; and individual cow and herd performance records.

2018年1月1日 · Hence, manipulation of rumen fermentation is crucial to optimize ruminal fermentation for improving nutrient utilization and productivity of the animals.

CRISPR/Cas9 construct with the ability to disrupt gene and introduce site-specific mutation precisely has been directly injected into zygote for zygote manipulation (cytoplasmic injection, or pronuclear or electroporation) .

As part of its charge, the committee was asked to prepare a subreport evaluating methods for detecting potential unintended compositional changes across the spectrum of messenger ribonucleic acid (mRNA), proteins, metabolites and nutrients that may occur in food derived from cloned animals that have not been genetically modified via genetic engi...

The new tools include the ability to transfer new genes into the genome of domestic animals, the genetic screening of embryos by DNA marker assisted selection to directly select for genes encoding desirable traits and against genetic defects, as well as the use of embryo bisection or cloning to produce identical copies of embryos from a genetica...
