Swine Diseases

The present-day graduate of veterinary medicine is quite well fitted by his technical training to enter into any of the many branches open to him. However, the technical training does not prepare one completely to meet actual field problems. I believe this to Lc true especially of those graduates who enter into general practice, and in this instance to one phase, i. e., swine practice. Therefore, the following is written with the hope that it may be of assistance in helping the recent graduate solve some of the problems confronting him

THE MEXICAN HOG INDUSTRY: MOVING BEYOND 2003

The purpose of this paper is to show how Mexican hog producers can take advantage of NAFTA in order to increase their competitiveness. In particular, lowering feed costs, improving transportation facilities, and establishing greater control over swine diseases would go a long way towards increasing the competitiveness of Mexican producers.Livestock Production/Industries,

We Can Eradicate Swine Diseases

Statistics indicate that four out of ten pigs born alive never go to market. And the six survivors are often marketed at an economic disadvantage because of diseases that retard their growth. Articles such as Has Disease Undermined the Swine Industry? , Are your Pigs worth a Penny? and We Have Too Many Sick Hogs point out how seriously the present swine disease situation is viewed by those close to and interested in the swine industry. As veterinarians or prospective veterinarians, we have a definite interest in good animal health and thus must be concerned about the seriousness of swine diseases. Any and all means of disease control which our profession can apply to relieve the swine industry should be given careful consideration. It is the purpose of this article to acquaint the veterinary student with a new and effective means of swine disease eradication

Modeling the live-pig trade network in Georgia: Implications for disease prevention and control.

Live pig trade patterns, drivers and characteristics, particularly in backyard predominant systems, remain largely unexplored despite their important contribution to the spread of infectious diseases in the swine industry. A better understanding of the pig trade dynamics can inform the implementation of risk-based and more cost-effective prevention and control programs for swine diseases. In this study, a semi-structured questionnaire elaborated by FAO and implemented to 487 farmers was used to collect data regarding basic characteristics about pig demographics and live-pig trade among villages in the country of Georgia, where very scarce information is available. Social network analysis and exponential random graph models were used to better understand the structure, contact patterns and main drivers for pig trade in the country. Results indicate relatively infrequent (a total of 599 shipments in one year) and geographically localized (median Euclidean distance between shipments = 6.08 km; IQR = 0-13.88 km) pig movements in the studied regions. The main factors contributing to live-pig trade movements among villages were being from the same region (i.e., local trade), usage of a middleman or a live animal market to trade live pigs by at least one farmer in the village, and having a large number of pig farmers in the village. The identified villages' characteristics and structural network properties could be used to inform the design of more cost-effective surveillance systems in a country which pig industry was recently devastated by African swine fever epidemics and where backyard production systems are predominant

Evaluating additives for swine rations (1993)

Swine producers today are making decisions about feed additives, which are promoted as an aid in reducing feed required per pound of gain. Additives on the market have been selected from a large number investigated for use in treatment of swine diseases or as growth promoters

Analysis of Swine Movements in a Province in Northern Vietnam and Application in the Design of Surveillance Strategies for Infectious Diseases

While swine production is rapidly growing in South-East Asia, the structure of the swine industry and the dynamic of pig movements have not been well-studied. However, this knowledge is a prerequisite for understanding the dynamic of disease transmission in swine populations and designing cost-effective surveillance strategies for infectious diseases. In this study, we assessed the farming and trading practices in the Vietnamese swine familial farming sector, which accounts for most pigs in Vietnam, and for which disease surveillance is a major challenge. Farmers from two communes of a Red River Delta Province (northern Vietnam) were interviewed, along with traders involved in pig transactions. Major differences in the trade structure were observed between the two communes. One commune had mainly transversal trades, that is between farms of equivalent sizes, whereas the other had pyramidal trades, that is from larger to smaller farms. Companies and large familial farrow-to-finish farms were likely to act as major sources of disease spread through pig sales, demonstrating their importance for disease control. Familial fattening farms with high pig purchases were at greater risk of disease introduction and should be targeted for disease detection as part of a risk-based surveillance. In contrast, many other familial farms were isolated or weakly connected to the swine trade network limiting their relevance for surveillance activities. However, some of these farms used boar hiring for breeding, increasing the risk of disease spread. Most familial farms were slaughtering pigs at the farm or in small local slaughterhouses, making the surveillance at the slaughterhouse inefficient. In terms of spatial distribution of the trades, the results suggested that northern provinces were highly connected and showed some connection with central and southern provinces. These results are useful to develop risk-based surveillance protocols for disease detection in the swine familial sector and to make recommendations for disease control. (Résumé d'auteur

Detect and Defeat

Kansas State University researchers take aim at deadly swine diseases. Late in 2015, scientists at Kansas State University and the University of Missouri delivered news that likely had swine producers worldwide rejoicing: The researchers had developed pigs that are resistant to porcine reproductive and respiratory syndrome, the most devastating disease in the industry
