Book Synopsis The Effects of Prostaglandin F2[alpha] on Reproductive Performance in the Postpartum Dairy Cow and the Mechanism Behind Its Benefits by : Kathryn Genevieve Younger
Download or read book The Effects of Prostaglandin F2[alpha] on Reproductive Performance in the Postpartum Dairy Cow and the Mechanism Behind Its Benefits written by Kathryn Genevieve Younger and published by . This book was released on 2016 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the beginning of the postpartum period, 80 to 100% of lactating dairy cows have bacterial contamination within their uteri. Presence of uterine bacteria may contribute to increased number of days open and services per conception within these cows. Expulsion of uterine contamination is crucial for uterine involution and reproductive health. Susceptibility to bacterial infection within the uterus can be attributed to a decrease in neutrophil function during the first two weeks of the postpartum period. Prostaglandin F2[alpha] (PGF2[alpha]) has been found to induce uterine contractility, increase neutrophil propagation and affect the uterine environment. The objective of this study was to determine the effects of a single injection of prostaglandin F2[alpha] (Lutalyse, Pfizer Animal Health, New York, NY) on uterine health and reproductive performance in dairy cows. Holstein cows from a commercial dairy were randomly assigned to receive an intramuscular injection of either Lutalyse or saline on Day 7 or 14 postpartum (Day 0= day of parturition). Services per conception and days open were evaluated to determine the effects on reproductive performance due to treatment. Cytobrush and uterine swabs were performed on a subset of Day 14 postpartum cows at 0 and 24 h after injection to evaluate changes in uterine neutrophil and bacterial populations. The pro-inflammatory cytokines known to induce mobilization of neutrophils, interleukin-1[beta], interleukin-6, and tumor necrosis factor-[alpha] were also measured at 0, 3, 6 and 12 h after injection of Lutalyse or saline on Day 14 postpartum to determine if PGF2[alpha] induced an increase in cytokines similar to initial pathogen detection. No significant differences were seen in days open, services per conception, interleukin-1[beta] or tumor necrosis factor-[alpha] concentrations. Interleukin-6 concentration was greater in saline cows at 12 h compared to Lutalyse treated cows at 3, 6 and 12 h after injection. Additionally, an increase in uterine neutrophils (P=0.05) and a decrease in bacteria (P=0.05) in response to Lutalyse were observed. Although PGF2[alpha] has been shown to have beneficial effects on the postpartum uterus, a single injection protocol may simply not be adequate to induce significant improvement in reproductive performance.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the results achieved so far by application of various biological systems (including genomics, transcriptomics, proteomics, and metabolomics) involved in the pathomechanisms and early diagnosis of periparturient diseases as specific biomarkers of disease in cattle. These emerging technologies help to extensively enhance our understanding of the etiology and pathogenesis of periparturient diseases of transition dairy cows. The book includes a chapter dedicated to ‘omics’ sciences and one that discusses the myths established in animal and veterinary sciences in recent decades and emerging, new paradigms. The diseases discussed include metritis, mastitis, laminitis, ketosis, rumen acidosis, periparturient immunosuppression, gastrointestinal microbiota and their involvement in disease, infertility, fatty liver, milk fever, and retained placenta. This book is intended for academics, veterinarians, animal nutritionists, researchers, and graduate students working in the field of ‘omics sciences’ with a special interest in dairy cattle health.

Book Synopsis Animal Agriculture by : Fuller W. Bazer
Download or read book Animal Agriculture written by Fuller W. Bazer and published by Academic Press. This book was released on 2019-10-25 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Agriculture: Sustainability, Challenges and Innovations discusses the land-based production of high-quality protein by livestock and poultry and how it plays an important role in improving human nutrition, growth and health. With exponential growth of the global population and marked rises in meat consumption per capita, demands for animal-source protein are expected to increase 72% between 2013 and 2050. This raises concerns about the sustainability and environmental impacts of animal agriculture. An attractive solution to meeting increasing needs for animal products and mitigating undesirable effects of agricultural practices is to enhance the efficiency of animal growth, reproduction, and lactation. Currently, there is no resource that offers specific knowledge of both animal science and technology, including biotechnology for the sustainability of animal agriculture for the expanding global demand of food in the face of diminishing resources. This book fills that gap, giving readers all the necessary information on important issues facing modern animal agriculture, namely its sustainability, challenges and innovative solutions. - Integrates new knowledge in animal breeding, biotechnology, nutrition, reproduction and management - Addresses the urgent issue of sustainability in modern animal agriculture - Provides practical solutions on how to solve the current and future problems that face animal agriculture worldwide
Book Synopsis Using Science to Improve the BLM Wild Horse and Burro Program by : National Research Council
Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

This book was released on 2021-04-23 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the scientific contributions published within the Animals topical collection “Feeding Strategies to Improve Sustainability and Welfare in Animal Production”. Originally a Special Issue, it has turned into a permanent collection, with its first article being published in July 2019 and more than 30 published articles a year later: evidence of the great interest from the scientific community regarding the topics addressed. The articles, which are grouped by species (poultry, ruminants, pigs, etc.) and by topic, deal with a wide range of arguments that, first of all, highlight the extraordinary complexity and diversity that exists in the animal production sector, and then, the great influence that nutrition and feeding can have in terms of optimizing the use of environmental resources and improving the welfare of farmed animals. In addition, all this is closely connected with the urgent need to safeguard the resources of the planet on which we live.
