Fisheries In Sundarbans: Problems And Prospects, Ganesh Chandra, R L. Sagar

Ganesh Chandra

Sundarbans, the largest delta on the planet earth is famous for its marine and estuarine fish resources. A large population is dependent on fishery activity and capture fisheries is treated as the backbone of Sundarban economy. Sundarban boast around 172 species of fishes, 20 species of prawn and 44 species of crabs including two edible crabs. But fisheries in Sundarbans faces some difficult problems which have an impact on the biodiversity, sustainability and livelihood of fish resources and fisher folk viz. shrinking tiger prawn population, indiscriminate fish seed collection, lack of post harvest and other infrastructures, natural calamities such as …

Acceptance Of Golden Rice In The Philippine Rice Bowl, Mark Chong

Research Collection Lee Kong Chian School Of Business

Few science issues in recent years have elicited such polarized public reactions as modern biotechnology and its agricultural applications. Although a new study conducted by the University of Illinois at Urbana-Champaign and the International Service for the Acquisition of Agri-biotech Applications (Ithaca, NY, USA) indicates that Southeast Asian stakeholders generally hold positive views about agricultural biotechnology.

Interpreting Bids From A Vickrey Auction When There Are Public Good Attributes, Sean P. Hurley, James B. Kliebenstein

Agribusiness

This paper provides a model that allows for interpreting bids in a Vickrey auction when the good has public good attributes. It also examines information obtained from a Vickrey auction, which collected consumer’s willingness-to-pay for pork products that had embedded environmental attributes, and applies the new interpretation to the bids.

A Tale Of Two Premiums—Examining Bids From A Multiple Round Vickrey Auction With Differing Information Sets, Sean P. Hurley, James B. Kliebenstein

Agribusiness

Two definitions of willingness-to-pay derived from a Vickrey auction with multi-product and multiple rounds with different information sets are examined. These definitions are examined in the context of valuing pork products with embedded environmental attributes and we show how information can have adverse effects on a base product of comparison.

Dairy Cow Ownership And Child Nutritional Status In Kenya, Charles F. Nicholson, Lucy Mwangi, Steven J. Staal, Philip K. Thornton

Agribusiness

This study examines the hypothesis that dairy cow ownership improves child nutritional status. Using household data from coastal and highland Kenya, three econometric model formulations are estimated. Positive impacts on chronic malnutrition are observed for coastal Kenya. No negative effects on acute or chronic malnutrition are found for either region.

Dairy Policy And Price Volatility, Charles F. Nicholson, Thomas Fiddaman

Agribusiness

The US dairy industry is shaped by a patchwork of regulations accumulated over a long history of intervention to achieve various, sometimes conflicting, policy goals. Price supports have long been a central feature of dairy markets, but were largely withdrawn beginning in 1988. Since that time, there has been a dramatic increase in the variability of farm milk and milk product prices. The origins and desirability of volatility has been the subject of much debate; unfortunately models in existence to date have shed little light on the question due to their adoption of essentially non-dynamic methods. This article introduces a …

Predicting Nutritional Requirements And Lactation Performance Of Dual-Purpose Cows Using A Dynamic Model, O. Reynoso-Campos, D. G. Fox, R. W. Blake, M. C. Barry, L. O. Tedeschi, C. F. Nicholson, H. M. Kaiser, P. A. Oltenacu

Agribusiness

A dynamic application of the Cornell Net Carbohydrate and Protein System (CNCPS) model was developed to predict annual cycles in animal nutrient requirements and performance of dual-purpose (milk and beef) cows. Interactions from mobilisation and repletion of body tissue reserves and feed biological values are accounted with a time step of one day, which considers physiological status of the animal, variation in dietary composition, and other environmental factors. This outcome was achieved by modifying the input and output structure of the CNCPS version 4.0 to compute body weight and changes in body reserves based on predicted milk production, intake of …

Agroecosystems Analysis From The Grass Roots: A Multidimensional Experiential Learning Course, Mary Wiedenhoeft, Steve Simmons, Ricardo Salvador, Gina Mcandrews, Charles A. Francis, James W. King, David Hole

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

An intensive, experiential travel course in Agroecosystems Analysis was conducted in Iowa, Minnesota, and Nebraska (United States) during summers of 1998 and 1999. The intended student audience was advanced undergraduate and beginning graduate students. Pretravel readings and a week-long series of farm visits, which consisted of in-depth interviews with the farmers and their families, prepared student teams to analyze and evaluate the production, economic, environmental, and social sustainability of 10 farms. Students shared their analyses both orally and in written reports. Based on a multifaceted student evaluation process, we found that participants were highly motivated, strongly engaged with the course …

Effects Of Three Types Of Free-Stall Surfaces On Preferences And Stall Usage By Dairy Cows, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

One important criterion in choosing appropriate housing systems for dairy cattle is that the freestall provides a comfortable surface for the cow. This paper describes two experiments testing the effects of commonly used lying surfaces on stall preference and stall usage by Holstein cows. In both experiments, 12 cows were housed individually in separate pens. Each pen contained three free stalls with a different surface: deep-bedded sawdust, deep-bedded sand, and a geotextile mattress covered with 2 to 3 cm of sawdust. The animals were restricted to each surface in turn, in a random order for either 2 (Experiment 1) or …

The Tenderisation Of Shin Beef Using A Citrus Juice Marinade, Roisin Burke, Frank Monahan

Articles

The effectiveness of organic acids (acetic, citric, lactic) and a citrus juice marinade as tenderising agents in shin beef muscle was investigated. At 0.2 M, citric acid was more effective as a tenderising agent than acetic or lactic acid. Immersion of shin beef strips in citric acid (0–0.05 M) showed that a significant tenderising effect was obtained above a concentration of 0.013 M. When shin beef strips were immersed in the citrus juice marinade (31% orange juice, 31% lemon juice, 38% distilled water) mean pH decreased from 5.7 to 3.1 and mean sample weight increased by ∼65%. The mean Warner–Bratzler …

Horse Welfare Since 1950, Katherine A. Houpt, Natalie Waran

State of the Animals 2003

There are approximately 6.9 million horses in the United States, more than in any other country in the world (American Horse Council 2000) (Table 1). That fact alone should inspire Americans to improve equine welfare, although it must be said that the state of domesticated horses is better now than it was fifty years ago.

At the turn of the millennium, the most pressing welfare issues of the domestic horse surround conditions found in slaughter and transport to slaughter; pari-mutuel racing; the pregnant mare urine (PMU) industry; the competitive and show industry; and in the development of husbandry-related stereotypes. (Urban …

The Eu Ban On Battery Cages: History And Prospects, Michael C. Appleby

State of the Animals 2003

On June 15, 1999, the European Union (EU) passed a directive on the welfare of laying hens, requiring that battery cages (so called because they are arranged in batteries of rows and tiers) be phased out by 2012. Enriched laying cages (which may also be arranged in batteries but which provide increased area and height, when compared with conventional cages, and a perch, nest box, and litter area) will still be allowed. This chapter outlines how this directive came about, and the social, economic, and political issues involved. It considers prospects for the future, both within and outside the EU, …
