Perspectives for feed-efficient animal production.
Modern animal breeding programs are largely based on biotechnological procedures, including AI and embryo transfer technology. Recent breakthroughs in reproductive technologies, such as somatic cell nuclear transfer and in vitro embryo production, and their combination with the emerging molecular genetic tools, will further advance progress and provide new opportunities for livestock breeding. ...
متن کاملAnimal production for efficient phosphate utilization: from optimized feed to high efficiency livestock.
Phosphorus (P) is an essential nutrient for livestock but its efficiency of utilization is below 40%, contributing to environmental issues. In this review, we summarize recent approaches to optimize P availability in livestock diets and improve its utilization efficiency. Phase feeding could potentially reduce P excretion by 20%. Addition of phytase enzymes to diets increased P availability fro...

The majority of this account concerns the relationships between efforts to improve animal production efficiency and acceptability of aspects of the systems which have been developed. How...
متن کاملSymposium: Fundamentals of Feed Efficiency: Animal to Genome
The measurement of feed efficiency in the broiler industry is one of pri mary measurements used to monitor and evaluate broiler performance. It has a significant impact on the competitiveness in the marketplace as nearly 70% of the cost of raising a commercial broiler is feed. Although feed costs may shift up or down, it will always represent the highest input cost in commercial poultry produc...
