Feed oxidation: What are the dangers? In pig diets, various sources of lipids are added to increase caloric density, provide essential fatty acids, improve feed palatability, improve pellet quality, and reduce dust (Keer et al., 2015). Some of the feed ingredients...

Introduction Nursery pig diets have been conventionally formulated with animal protein sources and dairy products (e.g., fish meal, plasma meal, and whey protein). However, this has resulted in a complex diet composition and high feed costs. Many attempts have therefore been made to simplify the conventional complex diet by increasing the proportion of soybean meal as a way to save on feed costs in nursery pig production. Previous studies (Skinner et...

Introduction Advances in genetics has certainly produced commercial strains of poultry and pig with greater performance (e.g. growth, reproduction) with minimal feed input. For example, over the last 5 decades, the body weight of broilers at 42 days has increased by 25-50 g per year and the feed conversion ratio to 2 kg body weight has improved 2-3 points annually (Havenstein et al., 2003; Gous, 2010; Aviagen, 2019). With the introduction of crosses in...

Introduction Trace minerals are essential elements in the maintenance of life for man and animal. However, what is not well understood or appreciated is how absorption and retention of these minerals can affect animal and human wellbeing, psychological status, health, and performance. While required in small amounts, just milligrams per day, trace minerals play critical roles as catalytic, regulatory, and structural components in multiple enzyme and...

Introduction
The protein is an essential nutrient for every animal diet. It is a source for growth, maintenance, immunity and production for all animals. Actually, every animal species have they own requirement for amino acids. The amino acids are classified as essential amino acids or nonessential amino acids. The essential amino acids are the one not synthetized in vivo and need to be supplier for the diet. There is another...

Introduction Although bacteria are too small to be seen without the aid of a microscope, their abundance by mass has been estimated to be 1,166 times larger than the mass of all humans. All animals contain populations of bacteria on outer and inner body surfaces such as the skin and the gastrointestinal tract, with the gastrointestinal tract being by far the most densely populated. It has been estimated that cattle, sheep, goats, pigs, chickens, ducks...

INTRODUCTION Sow productivity has increased considerably in recent years, mainly owing to an increase in litter size, which has resulted in an increased metabolic demand for nutrients to support fetal growth and colostrum and milk production (TOKACH et al., 2019). However, this increase in nutritional requirements has not been accompanied by the pattern of sow intake, thus, sows undergo excessive mobilization of body protein during lactation (YANG et al., 2000a). This can affect...

Introduction Antimicrobial additives have been used since the 1950s and are an important alternative to allow adequate productivity for animals raised under increasingly intensive conditions. As a consequence of the widespread use and results of AGP in livestock production, there is interest in the study of these additives by meet industry and the academic community. A total of 68.200 publications are presented as results when using the words “broiler” and...

Introduction This article identifies the most significant research innovations that, in our opinion, have been applied by the North American pork industry in the past decade. They are primarily the result of leading edge research in North America. Research discoveries were not considered unless they were being integrated into practice, with the exception of gene editing for pathogen control, which is in the approval process. Innovations that we identified as...

COMMON PROBLEMS IN BREEDING SOWS The high prolificacy of modern genetic lines provides extraordinary productivity, but at the same time increases the frequency of problems which, if not managed properly, will increase the culling rate. Among the main challenges we can...

Introduction Parasites have long been neglected but nowadays are becoming more recognized as important foodborne pathogens. Various factors contribute to their undervaluation such as complex lifecycles and transmission routes, prolonged incubation period and chronic disease manifestations. In addition, rapid and sensitive diagnostic assays are not always available and therefore parasite occurrences are often underreported, resulting in low disease...

Introduction A gastrointestinal tract (GIT) that functions in an optimum way clearly is of importance to the overall metabolism, physiology, disease status and performance of pigs of all stages of growth and development, and especially in the sensitive post-weaning production period. Disruptions (dysbiosis) in the GIT after weaning caused by internal and external influences can cause large economic losses in the pork industry, therefore the period after...

The Pasteurellaceae family and its importance in pig production The Pasteurellaceae family is comprised of a group of Gram-negative coccobacilli bacteria that inhabit the respiratory, oral or gastrointestinal tracts of different animal species and can cause a wide range of infectious diseases in animals and humans. The family includes at least three important and well-characterized bacterial genera; namely, Pasteurella ,...

Introduction The controversy that disease was transmitted by invisible life forms stretches back centuries dating to Aristotle (300BC) who believed that all life originated from soil and Virgil (40BC) who believed that bees came from honey and maggots originated from warm meat. It was Spallanzani who showed that no maggots arose from boiled meat while others showed that simple cotton filters could prevent spontaneous generation of life from warm meat. The...

Introduction During the last decades, the use of data by farmers has been limited. Most of the systems used were simple and mainly focused on the management of farm tasks, with limited or no capacity of analysis. Integration of data from different devices or farms was also difficult, and there was little applied knowledge on the value of data in the strategic decision-making. Another weak point, not solved so far, is the lack of support services in use of...

Introduction Resilience was historically ignored in commercial swine breeding programs. One reason was that breeding companies need to supply high health animals to the commercial sector of the swine industry. Nucleus herds needed to be naïve or at least negative for major diseases such as porcine reproductive and respiratory syndrome virus (PRRSv), Actinobacillus pleuropneumoniae (APP), Mycoplasma hyopneumonaie , and other major diseases....
