Available in PDF, EPUB and Kindle. Book excerpt: This work estimates probit and tobit models of the adoption of recombinant bovine somatotropin (rbST) on Connecticut dairy farms and then endogenizes that adoption in estimates of milk production and farm profit rates. The work improves on the current literature by allowing the rbST decision to be both continuous and contingent on other technology adoption decisions. The results show that larger farms, with more productivity technologies, and with younger, more educated farmers, are more likely to adopt rbST. While rbST is shown to significantly increase milk production, there is no evidence that it increases profits on a per cow basis.

Download or read book The Empirical Impact of Bovine Somatotropin on a Group of New York Dairy Farms written by Zdenko Stefanides and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data from a panel of New York Dairy farms were used to estimate bST adoption functions, and to measure the impact of bST on milk output and profitability per cow. Adoption results are consistent with previous ex ante bST adoption studies. Farm size, productivity, and education of the principal operator are the most important explanatory variables influencing adoption. The use of bST was found to significantly increase milk output per cow net of other explanatory variables, correcting for self-selection with respect to bST use. The impact on profits was, however, not statistically different from zero at any conventional statistical significance level.

Book excerpt: This dissertation examines the adoption and disadoption of recombinant bovine somatotropin (rbST), a genetically engineered hormone used to increase milk production, in the U.S. dairy industry, through three distinct analyses. In chapter two, I use limited dependent variable models to identify the factors correlated with the adoption and disadoption of rbST, and non-parametric and parametric duration models to identify the underlying dynamics of the technology choice decisions. Using 2005 national data, I find that rbST use appears to have plateaued; further, over 29 percent of producers who have ever used rbST had disadopted it by 2005. More importantly, my results suggest that there are differences between the adoption and disadoption decision and that the two processes are not mirror images of one another. Chapter three focuses on two recent events industry members and observers hypothesized had major effects on rbST use: a shortage of rbST in 2004 and a ban on the sale of milk from cows treated with rbST by several large retailers in California in 2007. I use discrete-time duration analysis to estimate the effect of the two shocks on the probability of rbST disadoption using survey data I collected in California in 2008. The results suggest that the shortage in 2004 had a negligible effect on disadoption while the ban in 2007 had a major effect on the decision to disadopt rbST in 2008. In chapter four, I consider the case where the use of a new technology leads to perceived differences in product quality, and construct a theoretical model of technology choice that considers a market with differentiated goods. I model the producer's decision to adopt and disadopt an agricultural technology and integrate it into a market-level analysis that links the industry's use of the technology to the structure of consumer demand. My analytical results suggest that the perception of product differentiation reduces the intensity of adoption when consumers perceive the new product to be weakly inferior. Moreover, producers take longer to learn about the true profitability of a new technology when consumers' perceive differentiated products.
Download or read book Impact of Recombinant Bovine Somatotropin on Dairy Farm Cost of Production written by Loren Tauer and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York dairy farm data over the years 1994-2002 were used to estimate the impact of recombinant bovine somatotropin (rbST) use on the cost of producing a hundredweight of milk. Both fixed and random effects models were estimated. Self-selection bias in the use of rbST was not found to exist. Results imply that the use of rbST on these dairy farms reduces the net cost of producing a hundredweight of milk somewhere between $0.23 and $0.52. For 20,000 pound average per-cow production, this would be a net cost reduction of $46-104 per cow.
Download or read book Metabolic Modifiers written by National Research Council and published by National Academies. This book was released on 1994-02-01 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.

This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

Book excerpt: Milk has played a major contribution to the human diet in many different countries across the world since the dawn of time. The dairy cow was domesticated over 6000 years ago, she was the object of worship in the Middle East 2000 years before Christ, and milk and milk products are mentioned more than 50 times in the Bible. Milk and dairy products have become a major part of the human diet in many countries. It is not surprising therefore, that over many years considerable attention has been paid to improving the quality of milk. We have worked to improve the yield, the compositional quality and the hygienic quality, and have striven to minimise the level of contaminants which can find access to this, perhaps our most natural, unrefined and highly nutritious foodstuff. The chain of people involved in the milk industry extends from milk production-farmers, veterinarians and farm advisors-through transport to processing-quality controllers, manufacturers-and on to retailers, legislators, nutritionists, dairy educators and consumers. All will be interested in the quality parameters of milk which are reg ularly measured for commercial reasons, for trade, for legal requirements and for reasons of nutrition.
Download or read book The Economics of Quarantine and the SPS Agreement written by Kym Anderson and published by University of Adelaide Press. This book was released on 2012 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Uruguay Round of multilateral trade negotiations, culminating in the GATT Secretariat being transformed into the World Trade Organization (WTO) on 1 January 1995, has altered forever the process of quarantine policymaking by national governments. On the one hand, WTO member countries retain the right to protect the life and health of their people, plants and animals from the risks of hazards such as pests and diseases arising from the importation of goods. On the other hand, the WTO's Agreement on Sanitary and Phytosanitary Measures (the SPS Agreement) requires that quarantine measures be determined in a manner that is transparent, consistent, scientifically based, and the least trade-restrictive. This collection resulted from an international workshop funded and organised by Biosecurity Australia, the agency of government responsible for analysing Australia's quarantine import risks and for negotiating multilateral SPS rules and less restrictive access to overseas markets for Australian produce. The workshop, which was held at the Melbourne Business School on 24-25 October 2000, brought together a distinguished group of applied economists and quarantine policy analysts whose focus involves regions as disparate as Europe, North America, Africa, Asia and New Zealand, in addition to Australia.
