This book is the product of the Conference on Nutrition and Human Reproduction, supported and organized by the National Insti tutes of Child Health and Human Development, and held at the National Institutes of Health, Bethesda, Maryland, in February 1977. The genesis of this Conference came from the work of the Subcommittee on Nutrition and Fertility of the Committee on International Nutrition Programs of the National Research Council. The purpose of the Conference was to assemble scientists and program planners from a broad range of fields including nutrition, epidemiology, demography, endocrinology, sociology, economics, anthropology, biostatistics and public health. Each individual brought his or her analytical skills and perspective to the meeting, with the goal of developing a more coherent picture of the many facets of nutrition and reproduction. The approach was to get a more comprehensive view by: 1. Clarifying terminology and definitions. 2. Reviewing recent and current work on the biological basis for nutrition-fertility interactions. 3. Reviewing biomedical and socioeconomic factors related to breast-feeding to assess how this practice relates to maternal and infant nutrition and fertility. 4. Assessing some current analytical models for defining nutrition-fertility interrelationships. 5. Reviewing recent field studies from Africa, Asia and Latin America which are examining the interrelationships of nutrition and reproduction.

Genetics of Reproduction in Sheep is a compilation of papers that are concerned with the study and application of genetics to the reproduction in sheep. The book is divided into six parts, grouping the papers according to topic. The main topics include genetic variation and selection; the inheritance and the effects of the Booroola gene; genetic strategies for single genes; physiology of genetic variation; the physiological criteria of genetic merit; and the national requirement and systems of husbandry. The text is recommended for those involved with raising sheep and plan to apply genetics in their reproduction, as well as for geneticists who wish to conduct studies on how their field is applied to sheep reproduction.

One of the little known species in the danger of extinction, gymophionan amphibians, are also known as caecilians or apoda. Gymnophiona contains 154 species belonging to 34 genera and 6 families. For many years, studies on the Gymnophiona were disparate and still only a few species have been deeply studied. Fortunately, in recent years, some new wo

"Understanding reproduction in marine fishes is critical to their conservation. It is also a fascinating topic in its own right. This book is now the best single reference on the subject, with original insights, analysis, and information. Anyone interested in the fascinating diversity of ways fish reproduce will want to have a copy of this book handy."--Peter Moyle, co-author of Protecting Life on Earth "Cole has assembled the internationally recognized authorities and they successfully cover topics of critical interest to behaviorists, ecologists, anatomists, physiologists, and conservation biologists. These experts demonstrate the amazing diversity and complexity of sexual and reproductive characteristics that have evolved among marine fishes."--Gene Helfman, co-author of The Diversity of Fishes: Biology, Evolution and Ecology "Kathleen Cole and her contributing authors raise from the depths of ignorance many neglected themes in the reproductive biology and fluid sexuality of marine fishes. The sheer richness of the data and the enthusiastic, engaging and thoughtful ways in which they are presented will encourage further research and discovery in biology of marine fishes and their complex and dynamic habitats."--Lynne Parenti, co-author of Comparative Biogeography

A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

This volume contains 44 papers and 2 abstracts from a international conference on African small ruminants research and development. eleven papers and 1 abstract deal with the importance of small ruminant production systems and economics. Another 11 describe and analyse feed resources and feeding systems and there are 6 papers on reproductive problems and their solutions. Seven papers and 1 abstract review the prevalent health problems under various management systems and present the solutions to these production constraints. The last 9 papers deal with breeds, breeding systems and breed improvement.
