Control of Pig Reproduction


Book Description

Control of Pig Reproduction focuses on carefully evaluated techniques and technologies involved in the control of pig reproduction. The selection first ponders on the sexual development of male pigs, including early fetal, perinatal, and pubertal periods. The text also discusses testicular steroids and boar taint; interrelationships between spermatozoa, female reproductive tract, and egg investments; and artificial insemination. Discussions focus on androgens, estrogens, deposition of semen and uterine transit, sperm regulation and release by the isthmus, and types of artificial insemination. The manuscript examines endocrine control of sexual maturation in female pigs and sexual differentiation of the stimulatory estrogen feedback mechanism and factors affecting the natural attainment of puberty in gilts. Discussions focus on development of ovarian function and gonadal steroid levels; development of the stimulatory estrogen feedback mechanism; and maturation of negative feedback of gonadal steroids. The text also takes a look at controlled induction of puberty, endocrine control of the estrus cycle, and control of ovulation. The selection is a valuable reference for farmers and readers interested in pig reproduction.




Control of Pig Reproduction VIII


Book Description

As a continuation of the earlier volumes in this series, the proceedings of the Eighth International Conference provide authoritative and up-to-date information on pig reproduction research. This volume, which contains manuscripts accompanying the state-of-the art lectures, the parallel sessions, and the expanded abstracts, provides an authoritative and up-to-date source of information on research in pig reproduction. This text is an invaluable resource for students, teachers, veterinarians, animal scientists, consultants, and technologists with an interest in all aspects of pig reproduction.

As a continuation of the earlier volumes in this series, the proceedings of the 8th Conference provide an authoritative and up to date source of information on research in pig reproduction. This will be an invaluable resource for students, teachers, veterinarians, consultants and technologists with an interest in all aspects of pig reproduction.




Control of Pig Reproduction VI


Book Description

The papers in this Supplement address many aspects of pig reproduction, including: development of the follicle and the corpus luteum, oocyte development in vivo and in vitro, fertilization in vivo and in vitro, embryonic and placental development, gestation and parturition, and new technologies including somatic cloning and functional genomics. basic molecular and cellular biology, which provide new insight into pig reproductive physiology and regulation. These papers provide an authoritative source of information that will be invaluable for students, teachers, researchers, veterinarians, consultants and technologists interested in all aspects of pig reproduction.




Model Code of Practice for the Welfare of Animals


Book Description

This new edition of the Code is intended as a guide for all people responsible for the welfare of pigs under both intensive, deep litter and outdoor systems. Good welfare of farmed pigs will ensure that pigs cope well in their environment and that factors such as growth, reproductive performance, disease levels, injuries and death rates are within industry standards. The Code recognizes that the basic requirement for the welfare of pigs is a husbandry system, managed by trained and skilled stock-people to ensure that basic needs of pigs are met: * Readily accessible appropriate and sufficient food and water * Adequate shelter to protect from climatic extremes * Opportunity to display appropriate patterns of behaviour * Physical handling in a manner which minimizes the likelihood of unreasonable or unnecessary pain or distress * Protection from, and/or rapid diagnosis and correct treatment of injury or disease * Freedom for necessary movement including to stand, stretch and lie down * Visual and social contact with other pigs This Model Code of Practice for the Welfare of Animals has been prepared by the Animal Welfare Working Group (AWWG) for the Primary Industries Ministerial Council (PIMC). The AWWG is made up of representatives from CSIRO, Animal Health Australia, the Department of Agriculture, Fisheries and Forestry - Australia, and from each of the State Departments responsible for agriculture. Extensive consultation has taken place with industry and animal welfare organisations in the development of the Code. This new edition supercedes the Second Edition, SCARM Report 66
