Biosecurity and Disease Management in China’s Animal Agriculture Sector

China’s livestock production sector is changing rapidly to meet a variety of challenges. At the same time, China’s domestic consumers have begun to demand better quality and safer dietary protein sources; potential for international food market penetration has been compromised by food scandals; and her animal agriculture sector remains a concern for emergence of zoonotic diseases. The country is in the process of a major public animal health infrastructure upgrade, and is seeking better integration with international public animal health governance structures. The intent of this article is two-fold. We provide an overview of and commentary on China’s animal husbandry sector and animal disease control policies. We also assess weaknesses in its animal health and biosecurity infrastructure. China’s animal health administration countenances institutional weaknesses that are shared with higher-income countries, but her problems are more pronounced. Administrative failings include poorly demarcated and inconsistent oversight as well as failings in accountability. The need for professionalization of animal health careers, emphasis on quantity goals over qualitative metrics, as well as a want in scientific analysis and follow-through when prioritizing are other weaknesses. Government policy has been to promote larger-scale production, primarily to better secure wholesome food domestically. Production is changing in ways that may pose intermediate-term threats to animal and human health, but the longer-term outcome may be a production base that poses fewer concerns for global health

Effects of Gradient Photoperiod and Temperature on Energy Metabolism and Body Composition in Tupaia belangeri chinensis

In order to explore the adaptive changes in energy metabolism and body composition in response to a gradual reduction in both ambient temperature and photoperiod, male adult tree shrews Tupaia belangeri chinensis were raised under the conditions of 30 oC and 12L:12D photoperiod (control group). The treatment group was changed from 25 oC and 16L:8D photoperiod to 5 oC and 8L:16D photoperiod (treatment group) over a period of four weeks and then maintained at those conditions for a further 4 weeks. Changes in body mass, resting metabolic rates (RMR),energy intake, and wet and dry mass of organs and tissues were measured at the end of the acclimation. Body mass in treatment tree shrews was higher than control. RMR showed significant differences between groups. No significant differences were detected in dry matter intake, energy intake, and digestible energy intake in control tree shrews during the whole acclimation period, while these parameters were significantly increased within treatment tree shrews at the end of acclimation, and were significantly higher than those in control tree shrews. Small intestine and stomach dry mass, as well as the wet mass of small intestine, heart, lung, liver and kidney were significantly higher in treatment groups than in controls, but no significant differences were found in the mass of other organs and tissues. These results suggest that increasing body mass and energy intake, together with adjusting the mass of some organs and tissues, are important physiological changes in tree shrews to adapt the changing environmental conditions

Can poor farmers afford higher micro-credit interest rates than the un-poor?

Purpose – The purpose of this paper is to test whether there is higher return rate of investment for poor farmers than for un-poor farmers and to discuss its implication for poverty reduction microcredit rate policy. Design/methodology/approach – By using the household-level data of six provinces of China, farmer household production function is used in this paper to estimate the investment return rate of farmer. Findings – The paper indicates that regardless which kind of grouping standard is adopted, the investment return rates of poor farmer households in general are far lower than the non-poor. In general, the richer a farmer household, the higher is the return rate of his household productive operations. Practical implications – The study of this paper reminds policy makers that poverty reduction microcredit rate should really take endurance capacity of poor farmers for credit rate into accounting because of the low return rate of their family investment. Exorbitant credit rate should be avoided to protect the credit right of poor farmers. Originality/value – There is seldom study on the comparison of return rates of family operation investment between poor and un-poor farmers; there is also unenough empirical study on the rationality of high interest rate on poor households from the return rate of investment point of view. The authors expect this paper will have some contribution on these two points. </jats:sec

Optimizing Medical Enterprise’s Operations Management considering Corporate Social Responsibility under Industry 5.0

Corporate social responsibility (CSR) is the concrete practice of sustainable development at the enterprise level, emphasizing the human value in the production process. The proposal of Industry 5.0 begins to take the coordinated development between human and various production factors as one of the key points of corporate sustainable management. Therefore, this paper studies the optimization of medical enterprise’s operations management considering enterprise CSR under Industry 5.0. A mixed-integer programming (MIP) model is developed to maximize the CSR with the consideration of the impact of precision medical technologies such as surgical robots (SRs) and 3D bone printing on employee social welfare, corporate profits, social environment, and customer surplus value. An improved variable neighborhood tabu search (IVNTS) algorithm which combines the variable neighborhood tabu search (VNTS) algorithm and simulated annealing (SA) algorithm is designed to solve the model, and numerical experiments are analyzed to verify the effectiveness of the proposed IVNTS. The research aids medical enterprise to make reasonable operations management decisions, while providing a reference for the government to draft and implement related policies, thereby achieving sustainable social development.</jats:p

Influence of photoperiod on cold-adapted thermogenesis and endocrine aspects in the tree shrew (Tupaia belangeri)

Environmental factors play an important role in the regulation of a mammal’s physiology and behavior. Consequently, particular species may provide valuable models for understanding the regulation of energy balance. In the present study, tree shrews (Tupaia belangeri) were transferred from a short to a long day photoperiod in cold conditions, in order to test our prediction that short photoperiod may stimulate an increase in thermogenic capacity and energy intake in tree shrews. During the first four weeks of acclimation to short days, T. belangeri increased body mass, whereas during the second four weeks of acclimation to long days, the body mass of tree shrews decreased compared with the short day group. The increase in body mass reflected a significant increase in absolute amounts of body components, such as carcass mass. During long photoperiod associated with cold exposure, livers, kidney, and small intestine mass decreased. T. belangeri decreased resting metabolic rate and energy intake after exposure to long days while during the exposure to short days the shrews started to maintain a stable level after 28 days. Serum leptin levels were positively correlated with body mass, as well as resting metabolic rate and energy intake. The results show that T. belangeri may provide an attractive novel model system for investigation of the regulation of body mass and energy balance at individual levels. Leptin is potentially stimulated by the photoperiod and cold exposure and is responsible for body mass regulation and thermogenesis in T. belangeri.</jats:p
