Available in PDF, EPUB and Kindle. Book excerpt: Pasture-based diets can comprise completely of human inedible ingredients, support a resilient business model for the producer, and an animal welfare friendly image. However, increasing environmental challenges will require pasture-based systems to adapt and innovate. To ascertain optimal nutritional strategies to increase the nutrient use efficiency, productivity, and sustainability of these systems, a robust understanding of the nutrient supply from pasture is required. Therefore, the objectives of this research were: 1) to characterize the nutritive value of pasture using new and updated feed chemistry methods, 2) provide a more robust understanding of nutrient supply and microbial dynamics in lactating dairy cows fed pasture-based diets, 3) incorporate new understanding of protozoal dynamics into the microbial sub-model of the Cornell Net Carbohydrate and Protein System (CNCPS) v7.0, and 4) investigate nutritional strategies to optimize productivity from pasture-based systems. Results from laboratory analysis demonstrated that the neutral detergent fiber fraction of immature pasture comprises of a large potentially digestible pool that degrades rapidly. In addition, a large proportion of pasture N was estimated to be soluble and highly degradable in the rumen. An in vivo study was performed to determine the effects of rolled barley supplementation on cows fed pasture-based diets, which incorporated the omasal sampling technique, rumen evacuation, microbial isolation, and amino acid (AA) analysis. Cows supplemented with rolled barley did not increase overall performance and reduced ruminal and total-tract neutral detergent fiber digestibility; however, this was not mediated through a reduction in reticulorumen pH. Rolled barley supplementation increased microbial AA flow, which was likely due to the greater amount of fermentable carbohydrate digested in the rumen and a greater efficiency of microbial protein synthesis. Extensive rumen degradation of pasture AA, for both diets, indicated that cows consuming pasture-based diets exhibit a large dependence on microbial AA to support metabolizable AA supply. Protozoa N flow was not affected by diet; however, protozoa supplied a much larger amount of microbial N and exhibited shorter generation time than previously assumed, indicating that protozoa have the capability to grow and leave the rumen at high rates. Reparameterization of the coefficients of the protozoal sub-model in the CNCPS v7.0 considerable improved the ability of the model to predict AA flow, when compared with a literature data set. However, discrepancies between the predicted and observed Met and Lys flows indicated that further refinement is required while all other AA are predicted with fairly high accuracy. Finally, when investigating nutritional strategies to optimize productivity from pasture-based diets, results demonstrated that increased metabolizable protein supply allowed higher milk yield to be achieved, as metabolizable protein was more limiting than metabolizable energy. However, the high soil moisture deficit experienced during the study altered the chemical composition of the pasture, reducing the ability to extrapolate the results to cows consuming typical pasture-based diets. Overall, this research provides an enhanced understanding of the nutrient supply from pasture-based diets and highlights opportunities to increase the productivity and efficiency of pasture-based systems. Future studies incorporating the quantitative techniques described in this research are required to provide further insight into the nutrient supply of pasture-fed cows.

Jennings, Ph.d. and published by Createspace Independent Publishing Platform. This book was released on 2017-11-13 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: In respect of milk production from improved tropical pasture, it has been 'settled law' that: 1. Tropical pastures, by virtue of their greater photosynthetic capacity, are capable of twice out-yielding temperate systems in respect of annual tonnage of herbage production; thus establishing a platform for at least matching temperate countries in year round milk yield per hectare; 2. In sustaining unsupplemented individual yields of the order of 4000 litres per cow per year, the empirical evidence clearly supported the possibility of sustained international competitiveness in milk production by developing countries; 3. The key to the sustained transformation of this potential into economic advantage lay in developing a clear understanding of the dynamics at the 'sward-animal interface'. The interposing of the serially-discredited economic theory of 'Comparative Advantage' as the basis for global trading and economic relationships, effectively truncated the progress toward constructing a solid knowledge base as the foundation for sustained competitive advantage in milk production by developing countries; even as respected reviewers were systematically ignoring the supporting evidence generated by research over the past 60 years. Thanks to the innovativeness of Brazilian researchers, we are now at the juncture where the long accepted potential of tropical pastures for competitive milk production can now be transformed into sustained economic value. This work seeks to cohere the several strands of grassland research of the past five to six decades, into a template for optimizing the nutrition of the high-yielding grazing dairy cow on improved tropical pasture to the advantage of the peoples of the Caribbean tropics and beyond

Download or read book Grass Productivity An Introduction to Rational Grazing written by Dr. Robert C. Worstell and published by Lulu.com. This book was released on 2015-01-13 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: SIMPLE questions often help us to understand problems better; and I think it indispensable, at the beginning of this work, to ask a question which appears simple in the extreme: "What is grazing?" The answer is generally as follows: "Causing grass to be eaten by an animal." That is correct! But here is another answer which, to my mind, is more realistic: "Causing the grass and the animal to meet." Since this book is almost exclusively concerned with grazing by cattle, I propose the following definition to the reader, requesting him to allow it to become well impressed upon his mind: Grazing is the meeting of cow and grass. It is by satisfying as far as possible the demands of both parties that we will arrive at a rational grazing, which will provide us with maximum productivity on the part of the grass while at the same time allowing the cow to give optimum performance.

Download or read book Advances in Pasture Management and Animal Nutrition to Optimize Beef Cattle Production in Grazing Systems written by Elieder Romanzini and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand of meat requires the adoption of sustainable intensification livestock systems, applying nutritional strategies to reduce any negative contribution from beef cattle to global warming and, at the same time, to increase animal performance and productive efficiency. The pasture management practices and feed supplementation, mainly using non-edible feed with less costs, could minimize environmental and social impacts, resulting in higher productivity with less inputs utilization. Tropical grass submitted to grazing management according to plant height present high soluble protein and low levels of indigestible neutral detergent fiber contents. Energy or rumen undegradable protein supplementation, associated to alternative additives to antibiotics effects, such as probiotics, tannin, essential oils and saponin, can help to fully exploit the animal genetic potential and nutrient utilization efficiency, which decreases greenhouse gases emissions and improves animal performance. Hence, more information about these tools can make the livestock systems in tropical pasture more efficient and eco-friendlier.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
