Porcine reproductive and respiratory syndrome (PRRS) is a major viral disease of swine with devastating economic consequences to the swine industry. 1,2 Pigs of all ages are susceptible to PRRS virus, with highly variable clinical manifestations in different age groups of infected pigs, ranging from abortion, anorexia, and pyrexia in pregnant sows to respiratory signs, high mortality, and poor growth in young pigs. 3 Several direct and indirect mechanisms have been...
Introduction All living organisms depend on the continuous supply of available phosphorus (P) sources for a plethora of metabolic processes. Fertilizer and feed phosphates are obtained to a large extent from rock phosphate. This is a non-renewable resource, and the global distribution of rock phosphate reserves is not uniform. Concurrently, P accumulation in areas with high livestock production density may be harmful to the environment. Hence,...
Introduction Animals used for food production have been genetically selected for feed intake and muscle development (or milk and egg production) and are therefore divergent from their ancestors. In addition, these animals are reared in conditions that favor fast spread of pathogens. The high uptake of feed and the fast growth make these animals prone to intestinal disorders, what has been neglected in the past because of the use of low doses of...
Brad Freking (CEO and owner, New Fashion Pork) offered his thoughts on people, processes and systems during a Swine It interview with host Márcio Gonçalves....
Trey Kellner (Swine Nutritionist at AMVC) will talk about pros and cons, as well as the conditions needed, during a Swine It interview with host Márcio Gonçalves....
Chad Hastad (New Fashion Pork) discussed ongoing research in this area, during a Swine It interview with host Márcio Gonçalves....
Introduction Phytases of bacterial origin are the exogenous enzymes most widely used in the diets of monogastric animals, acting on the hydrolysis of phytate (myo-inositol 1,2,3,4,5,6-hexakis [dihydrogen] phosphate) to release the phosphate from this complex [1,2]. Phytases are commonly developed by means of genetic engineering [3], such as phytase from Escherichia coli expressed in Trichoderma reesei and phytase from Citrobacter braakii expressed in Aspergillus oryzae [2]. They...
To ensure that accommodations are proper, and health safety protocols are in place, the IPVS2022 Organizing Committee, the world´s leading technical and scientific event in the pig industry, travelled to Rio de Janeiro on an official visit to thoroughly assess the facilities that will host the Congress.
The IPVS first hybrid event is scheduled to place from June 21st to 24th, 2022 at Riocentro Convention Center and is expected to attract approximately 1,500 attendees from all...

FAYETTEVILLE, Ark. — Arkansas Agricultural Experiment Station scientists have developed bacterial cultivation methods to isolate different bacteria from pigs. These methods could be used to culture beneficial bacteria in swine intestinal, or gut, microbiomes that can serve as probiotics to protect or improve the health of pigs.

NEW POLICIES AND ACTIONS
"Dual control of energy consumption" has become a crucial driving force for the contradiction between supply and demand of the veterinary APIs market. On Sep 16, the state planning agency published new policy...
Introduction According to the FAO, livestock is one of the fastest growing sectors of global agricultural production. It is evolving in response to the rapid increase in demand for products of animal origin, especially in developing countries. In developed countries, through intensification practices that have helped increase yields and efficiency while bringing down costs, the demand for livestock products is stagnating and have to face many...
1. Introduction Increased recognition of the consequences of antimicrobial resistance (AMR) in humans and animals has led to monitoring and surveillance programs in many countries, often specific to the species being monitored [1]. They range in complexity from highly structured and regulated systems to those that are passive or reactive. Except for a few species of public health interest such as Salmonella spp. [2], current AMR surveillance for bacterial isolates recovered from...
