Japanese materialistic behavior and consumption trends are examined by comparing age‐cohort differences between the Japanese “new breed” and “second baby‐boomer age‐cohorts”. Price perception, brand loyalty, and shopping‐information sources of the two age‐cohorts are also assessed. Results suggest that the Japanese new breed is more materialistic, sensitive to prestige, brand loyal, and likely to use media as their shopping information source as compared to second baby‐boomer. On the other hand, second baby‐boomers are less materialistic, value conscious, less brand loyal, and more likely to rely on word‐of‐mouth communication as their information sources as compared to the Japanese new breeds.

The purpose of this paper is to investigate the impact of biotechnological inventions and innovations on the organization of the burgeoning Atlantic salmon farming industry.

The authors study how novel biotechnological inventions are utilized within Atlantic salmon aquaculture. The authors compare the findings with the historical development path of invention and innovation in the plant sector, and explore parallels and dissimilarities between the plant breeding sector and Atlantic salmon aquaculture.

The innovation capacity within Atlantic salmon aquaculture is distinct from the plant sector, but nonetheless likely to become equifinal. Similar to plants, the female fecundity of salmon is high. Hybridization, which is an effective mechanism for protection of investments in high fecundity organisms, is less effective in salmon farming because the genetic variability is higher in salmon. Hybridization provides plant breeders with significant power over grow-out farmers. The development path in Atlantic salmon sector is distinctively dissimilar from plants, but salmon farmers nonetheless appear to move toward the structural configurations that are parallel to the plant sector. The significance of new breeding technologies in Atlantic salmon farming ascends, and will play an increasingly important role in the further development of this industry.

The study contributes to the prevailing knowledge of how inventions and innovations influence the future development of the Atlantic salmon industry.

Biotechnological inventions are evolving within aquaculture. So far, the implications of novel biotechnological possibilities for the Atlantic salmon sector have been underanalyzed. The paper explores these implications from the perspective of political economy.

Why does a library need reference sources concerning the various breeds of dogs? What kinds of questions are likely to be encountered which could be answered by books of this type? Some of the questions I have been asked include: “What kind of a dog is a Puli?” “Do you have a picture of an Irish Setter I can copy?” “What breed of dog is good with children and can live in an apartment?” “Do Tibetan Terriers really come from Tibet?” “I saw this dog but I don't know what it is. Can you help me identify it?”

The purpose of this paper is to identify the risk factors that affect aquatic product quality in the “farming-supermarket docking” condition. This paper investigates how the investment scale can affect earnings and aquatic product quality assurance level. Also, it aims to determine an effective method for increasing aquatic product assurance level, coordinate the supply chain and improve management of the entire supply chain.

The authors construct a coordination model for quality risk control of the aquatic supply chain by simulating the model in a tilapia supply chain using the case study method. They applied Karush–Kuhn–Tucker conditions to analyze upstream enterprises (breeding base) and downstream enterprises (corresponding supermarket) under the conditions of sufficient or insufficient funds, Further, they consider the relationships among revenue, optimum quality assurance and investment scale at different capital positions; discuss the best cooperation conditions in four cases; and draw conclusions on ways to control quality risk.

The proposed coordination model is found to be effective in controlling aquatic product quality risk. The simulation results show that when the enterprise funds are sufficient, the sales prices, product freshness, quality assurance ability, collaboration and quality test ability have a positive influence on quality assurance level, whereas coefficient and price sensitivity have a negative influence on it. Additionally, it can obtain high-quality assurance levels and earnings in both breeding bases and supermarkets under the condition of adequate investment.

The study built a coordination model combined with the characteristics of the aquatic supply chain by adding the quality penalty mechanism, product freshness parameters and cost function in the “farming-supermarket docking” mode into the traditional principal–agent model. Research results are beneficial to enhancing the quality assurance level of the aquatic supply chain and improving the coordination level of the supply chain.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

The purpose of this study is to assess the effect of chicken breeds on quality characteristics of meat nuggets.

The formulation of meat nuggets prepared from meat of Cobb-400, Vanraja, Aseel and Kadaknath separately consisted of 60 per cent lean meat. The emulsion was prepared by standard method and moulded into nuggets. Cooking was performed under pressure (120°C/15 Psi for 30 min).

Emulsion and cooked nuggets both showed no significant differences in pH values among the breeds. Higher moisture and fat content was observed in emulsion and nuggets prepared from Cobb-400, while respective protein and ash was maximum in Kadaknath and Vanraja meat-based emulsions and nuggets. The per cent emulsion stability (87.04 ± 0.45) and cooking yield (85.24 ± 0.06) was reported highest in Cobb-400, which indicates the better water holding capacity and suitability of Cobb-400 meat for the development of nuggets at six weeks of age. The mean sensory scores for colour and appearance (7.12 ± 0.28), as well as flavour (7.00 ± 0.04), were significantly (p < 0.05) higher in Cobb-400 nuggets and lowest in Kadaknath (6.21 ± 0.03 and 6.65 ± 0.06). However, no significant differences were noticed in other sensory attributes among treatments.

The fatty acid and amino acid profile analysis may be helpful to understand the original nutritional difference in prepared nuggets.

The study will be off immense help in optimum utilization of meat of locally available chicken breeds for breed-specific and cost-effective product formulations.

The products will be acceptable to all commodities because it is made up of chicken meat.

The effect of chicken breeds on meat nuggets is relatively new aspect and essential to establish suitability of meat of locally available chicken breeds for product development.

In April we celebrate Pets Are Wonderful Month (PAW) to honor the companion animals that bring joy and love to their owners' lives. Humans have lived with animals as companions for thousands of years and during that time our knowledge about the animals we choose as pets has grown enormously. Recent research involving pet therapy indicates that not only do pets give us love and companionship, but they also are beneficial to our physical and mental health. Pets are used in nursing homes, prisons, and mental health institutions, with autistic children, and in many other capacities.

The products of transgenic technology have captured the attention of enthusiasts and detractors, but transgenics are just one tool of agricultural biotechnology. Other applications enable scientists to understand biodiversity, to track genes through generations in breeding programs, and to move genes among closely related as well as unrelated organisms. These applications all have the potential to lead to substantial productivity gains.

In this chapter we provide an introduction to basic plant genetic concepts, defining molecular markers, transgenic and cisgenic techniques. We briefly summarize the status of commercialized biotechnology applications to agriculture. We consider the likely future commercialization of products like drought tolerant crops, crops designed to improve human nutrition, pharmaceuticals from transgenic plants, biofuels, and crops for environmental remediation. We identify genomic selection as a potentially powerful new technique and conclude with our reflections on the state of agricultural biotechnology.

Research at universities and other public-sector institutions, largely focused on advancing knowledge, has aroused enormous optimism about the promise of these DNA-based technologies. This in turn has led to large private-sector investments on maize, soybean, canola, and cotton, with wide adoption of the research products in about eight countries. Much has been made of the potential of biotechnology to address food needs in the low-income countries, and China, India, and Brazil have large public DNA-based crop variety development efforts. But other lower income developing countries have little capability to use these tools, even the most straightforward marker applications. Ensuring that these and other applications of biotechnology lead to products that are well adapted to local agriculture requires adaptive research capacity that is lacking in the lowest income, most food-insecure nations. We are less optimistic than many others that private research will fund these needs.

A basic framework of Simulated Breeding, a type of interactive evolutionary computing to breed artifacts of which origin is Blind Watchmaker by R. Dawkins is considered. These methods, make it easy for humans; to design a complex object adapted to his/her subjective criteria, just similar to agricultural products that we have been developing over thousands of years. Starting from randomly initialised genome, the solution candidates are improved through several generations with artificial selection. Graphical user interface helps the process of breeding with techniques of multi‐field user interface and partial breeding. The former improves the diversity of individuals that prevents being trapped at local optimum. The latter makes it possible for the user to fix features that he/she already satisfied. These methods were examined through artistic applications by the author, SBART for graphics art and SBEAT for music. Combining with direct genome editor and exportation to another graphical or musical tool on the computer, they can be powerful tools for artistic creation. These systems may contribute to create a type of new culture.

The authors explicitly evaluate the dynamic impact of five most concerned supply chain disruption scenarios, including: (1) a short-term shortage and price jump of corn supply in hog farms; (2) a shortage of market hogs to packing facilities; (3) disruption in breeding stock adjustments; (4) disruption in pork import; and (5) a combination of scenario (1)–(4).

The agricultural supply chain experienced tremendous disruptions from the COVID-19 pandemic. To evaluate the impact of disruptions, the authors employ a system dynamics model of hog market to simulate and project the impact of COVID-19 on China hog production and pork consumption. In the model the authors explicitly characterize the cyclical pattern of hog market. The hog cycle model is calibrated using market data from 2018–2019 to represent the market situation during an ongoing African swine fever.

The authors find that the impacts of supply chain disruption are generally short-lived. Market hog transportation disruption has immediate impact on price and consumption. But the impact is smoothed out in six months. Delay in import shipment temporarily reduces consumption and raises hog price. A temporary increase of corn price or delay in breeding stock acquisition does not produce significant impact on national hog market as a whole, despite mass media coverage on certain severely affected regions.

This is the first evaluation of short-term supply chain disruption on China hog market from COVID-19. The authors employ a system dynamics model of hog markets with an international trade component. The model allows for monthly time step analysis and projection of the COVID-19 impact over a five-year period. The results and discussion have far-reaching implications for agricultural markets around the world.
