Available in PDF, EPUB and Kindle. Book excerpt: The object of this study was to improve our understanding of the process of boar induced first estrus in gilts. A technique for catheterization of the vena cava was refined and validated using valium and ketamine as anaesthetics. In a study to determine if hormone levels in pre-pubertal gilts could be used to predict age at first estrus, 70 gilts were blood sampled every three weeks, between 60 and 144 days of age, exposed to mature boars at 135 days of age, and monitored for estrus. Gilts studied during summer and responding to boar exposure with estrus before 200 days of age showed elevated LH concentrations at 81 days of age compared to gilts which failed to exhibit first estrus. FSH concentrations decreased in all gilts over time. A second study was conducted to determine which aspects of the pulsatile release of LH from the pituitary were increased at 81 days of age in gilts responding to boar exposure with first estrus. However, gilts which showed or failed to show first estrus had similar LH pulse amplitude, LH pulse frequency and basal serum LH concentrations. To study which aspect of the gilt's reproductive hormone profile is affected by boar exposure, serum concentrations of LH, FSH, estradiol and cortisol were measured in control, responding and non-responding gilts following introduction of a boar. In gilts responding to boar exposure with estrus, a transient increase in LH pulse frequency, mean LH and basal LH concentrations occurred immediately following boar introduction. FSH was lower in boar exposed gilts compared to controls gilts 10 and 20 days after boar introduction. Serum concentrations of cortisol were higher at all time periods in non-responding gilts. Estradiol concentrations were not affected by boar exposure. Hormone therapy was investigated as a possible solution to induce first estrus in gilts. Exogenous LH was given 4 times daily to gilts from 75 to 85 days of age. Basal serum LH concentrations were increased in treated gilts but there.

Download or read book Reproductive Technologies in Farm Animals written by Ian Gordon and published by CABI. This book was released on 2004 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past half century great progress has been made in the reproductive management of farm animals, both mammals and birds. This book aims to review developments and indicate which reproductive technologies can be used commercially or in research. It begins by discussing artificial insemination and how this has recently been refined in semen sexing technology. Embryo transfer, in vitro embryo production technology and the control of oestrus and ovulation are then reviewed. Subsequent chapters consider the control of postpartum ovarian activity, seasonal breeding, multiple births and litter size, pregnancy testing, parturition, and the onset of puberty. The author then describes more recent developments in cloning and the production of transgenic animals, before a final chapter on suppressing reproductive activity.

Download or read book Current and Future Reproductive Technologies and World Food Production written by G. Cliff Lamb and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species.
