INTRODUCTION Several factors influence piglet performance after birth. In general, pig producers aim at heavy birth and weaning weights because they are associated with better performance during subsequent rearing phases. This association was first described in the 1980s by Powell and Aberle (1980) and has been recently studied and discussed in the literature. However, Surek et al. (2014), working with litters of 11 piglets each standardized by birth weight, observed that...

INTRODUCTION One of the greatest challenges in optimizing growth performance and health of newly weaned pigs is to overcome low and variable feed consumption which adversely affects gastrointestinal health during this critical transition period on commercial swine farms (Pluske et al., 1997; Langendijk et al. 2007; Dong and Pluske, 2007). Therefore, dietary interventions that encourage faster adaptation and greater feed consumption, while also improving energy and...

Introduction Porcine Reproductive and Respiratory Syndrome (PRRS) is the most relevant infectious disease in the swine industry. PRRS virus (PRRSv) live inoculation has been used to stabilize and even eliminate PRRS in positively confirmed farms. Batch farrowing is a production system used to maximize productivity and could be used to interrupt disease transmission in susceptible populations. This report captures the stabilization of a one site farm with a continuous production...

A study was conducted to evaluate the effects of replacing corn by full-fat rice bran (FFRB) on performance and meat quality characteristics of growing-finishing pigs. A total of 728 pigs [Duroc x (Yorkshire x Landrace); initial body weight (BW) = 24.1 ± 0.11 kg] were randomly distributed to 4 dietary treatments with 7 replicate pens (26 pigs/pen) per treatment. Diets 1, 2, 3 and 4 were formulated replacing corn by 5%, 15%, 30%, and 45% of FFRB, respectively. Growth phases...

Introduction African swine fever virus (ASFV) reported as deadly for pigs. It is listed as a “notifiable disease” by the OIE due to high illness rates and a high mortality rate, up to 100%, and substantial financial losses [1-3]. Further spread of ASF to China has had disastrous consequences, especially instead of the fact that China contains more than half of the world’s pig population [4]. To date, as far as Vietnam is concerned, ASF has appeared in all 63...

Introduction Porcine Epidemic Diarrhea Virus (PEDV) is an enveloped single-stranded positive-sense RNA virus that was first identified in the United States in May 2013. Epidemiological and controlled experiments have shown that complete feed or feed components can be one of many possible vectors of transmission of PEDV. Because of the potential viral spread by feed and ingredients, reduction techniques such as chemical treatments have been used to combat the virus. Many chemical...

Cordyceps militaris is a rare and exotic Chinese medicinal mushroom. Its chemical composition and pharmacological effects are similar to C ordyceps sinensis . Cordyceps sinensis is widely used as a tonic for vitality and longevity for thousands of years by the Chinese. Cordyceps militaris has also been used in Chinese medicine for thousands of years. Easy-immune contains cordycepin and polysaccharides from Cordyceps as a natural immunity...

Introduction Minerals make up a small but vital percentage of swine diets with profound impacts on animal health, growth performance, feed cost and the general environment. Calcium and phosphorus are the two most abundant minerals in the body, and they exist largely (about 98%) in the form of carbonated hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) in the skeleton (Mahamid et al., 2010). They are required for a wide variety of functions...

This systematic review aimed to assess the effectiveness of pre-harvest interventions to control the main foodborne pathogens in pork in the European Union. A total of 1180 studies were retrieved from PubMed® and Web of Science for 15 pathogens identified as relevant in EFSA's scientific opinion on the public health hazards related to pork (2011). The study selection focused on controlled studies where a cause-effect could be attributed to the interventions tested, and...

Evidence suggests African swine fever virus (ASFV) may survive under conditions similar to those observed in transoceanic transport models. In a Swine Health Information Center (SHIC)-funded study, researchers developed a quantitative risk assessment model to estimate the probability that one or more corn or soybean meal ocean vessels contaminated with ASFV would be imported into the US annually. Ultimately, this model can be used to evaluate risk mitigation strategies and critical control...

Over the past decades, the use of therapeutic inclusions of zinc oxide in diets has been used to reduce the negative impact of the weaning process on the performance of piglets. Its effectiveness on diarrhoea reduction has led to an enormous increase in consumption of zinc oxide in...

Introduction In practice, an optimisation program is used to formulate commercial diets to meet the minimum nutrient constraints in order to minimise feed costs. With phytase, potentially unjustifiable high contributions will result in reduction of safety margins or even lead to nutrient and energy deficiencies with a negative impact on animal performance. When applying values, it is important to understand that it is not possible to compare matrices from different phytases...

Introduction Pork’s historic position as the world’s most popular meat is no more. 2019 was characterized by the explosion of African Swine Fever in China and subsequent slaughter of approximately half of that country’s pigs, representing about 25% of the world's production. Allowing for this catastrophe the exorable rise in the global consumption of chicken ensured it always going to result in its accession to No.1 spot worlds, but...

Introduction The African swine fever (ASF) virus (ASFV) is deadly to pigs but harmless to humans [1]. ASF is one of the most severe viral diseases affecting pigs worldwide [2-5]. It is considered a “notifiable disease” by the Office International des Epizooties (International Office of Epizootics [OIE] of the World Health Organization because of its high mortality rate of up to 100% [6-8]. ASF causes acute hemorrhagic fever in domestic pigs and often results in...

Maternal investment, sow behavioural needs and criteria for housing design The reproductive strategy of producing large broods and smaller young, resulting in a higher mortality rate, fits the picture of domestic pigs remarkably well (reviewed by Drake et al. 2008). The average litter size in domestic sows is around 12 to 14 piglets, but litters of above 20 piglets are not uncommon even in gilts, although the number of functional teats is usually between 14...

Introduction In a recent detailed review of the factors determining reproductive development in the gilt (Patterson and Foxcroft, 2019), we suggested that “Substantial evidence supports successful management of gilts as an absolutely necessary component of breeding herd management and the pivotal starting point for the future fertility and longevity of the breeding herd”. We also discussed the link between earlier sexual maturation and improved...

Introduction Although African swine fever (ASF) was first described almost a century ago, controlling the disease has proven to be a challenge, in particular because no vaccine or treatment are available. Spread of ASF can only be prevented by early detection and the application of strict compliance of classical disease control methods, including surveillance, epidemiological investigation, tracing of pigs, stamping out in infected holdings, strict...

Introduction Influenza A viruses (IAV) are the causative agents of one of the most important viral respiratory diseases in pigs and humans. Human and swine IAV are prone to interspecies transmission, leading to regular incursions from human to pig and vice versa. This bidirectional transmission of IAV has heavily influenced the evolutionary history of IAV in both species. Interspecies transmission of distinct human seasonal lineages, adaptation followed by...

Introduction The emergence of Porcine reproductive and respiratory syndrome virus in the 1980s and early 1990s was a turning point in the ways in which diseases were dealt with in pig farms. The impact of the disease, its rapid spread worldwide (by 1993 the infection was present in America, Europe and Asia) and the unusual features of the virus made evident that a vaccine was urgently needed to try to control the infection. The first vaccine...
