In today's world, we are witnessing simultaneous breakthroughs in reproductive technologies, genomics, and molecular biology. Advances in molecular genetic technology and understanding of the bovine genome have led to the development of tools that can be used to enhance profitability on cow-calf enterprises. Factors Affecting Calf Crop: Biotechnology of Reproduction provides a detailed compilation of current and forthcoming technology for managing reproduction in cattle.

The book discusses topics such as: approved techniques for controlling the estrous cycle in cattle; managing follicular growth with progesterone, estrogens, and prostaglandins; freezing, thawing, and transfer of cattle embryos; application of embryo transfer to the beef cattle industry; embryo transfer in topically adapted cattle; new factors affecting bull fertility; embryo collection and utilization technology, in vitro fertilization, somatic cell cloning, and genetic technologies; uses of real-time ultrasound; and sexed semen.

Over 25 leading animal scientists have combined their expertise to produce the first single-source reference that covers successful reproductive techniques that will, most likely, be the wave of the future. Expansive in scope, the book addresses current biotechnologies as they impact the production of beef cattle. Written at a level to appeal to the researcher, commercial producer, or student, Factors Affecting Calf Crop: Biotechnology of Reproduction presents you with a wealth of technologies applicable to animal agriculture.

Learn the plant life cycle the Montessori way!Based on the proven Montessori teaching method, Montessori: Seed Work introduces young readers to the plant life cycle, starting with seeds before moving on to each phase as the plant grows.

This book provides an environmental 'way in' to the science every primary science teacher needs to know under the ITT National Curriculum issued by the Teacher Training Agency. It builds constructively on the knowledge of and involvement in environmental issues possessed by practicing and student teachers, whether specialist or non-specialist scientists. Especially for the latter, science can be a daunting and difficult area of their teaching. The authors believe that, by way of an environmental emphasis, the science underpinning such practice can be acquired by most students, enabling them to build their confidence as effective science teachers, while developing environmental awareness and understanding in primary children.

Children need to experience nature, and gardening is a good way to encourage them to engage with the earth, plants and animals. Gardening classes, as taught in Steiner-Waldorf schools from Class 6 to Class 10, help children develop many important skills, including sensory perception and motor skills, as well as an understanding of ecology and agriculture. How can such a complex subject be taught well and effectively? In a clear structure -- which includes the history of school gardens, aspects of child development, and practical help on teaching methods, lesson planning for different age groups, and maintaining the garden itself -- Birte Kaufmann offers many useful tips and suggestions for new or developing gardening teachers.
