Summary:
Phytogenic feed additives (PFA), also known as phytobiotics or botanicals, are commonly defined as various plant secondary compounds (PSC) and metabolites with beneficial effects on animal health and production, including feed and animal products. Botanicals in animal production have different applications, including sensory phytogenic additives, technological additives for improvement of feed quality and safety, as well as additives promoting animal health and welfare, acting as immunomodulators, antioxidants, digestive stimulants, and substances that can increase the performance and quality of animal products. This study is focused on available microencapsulation techniques of EOs to increase the bioavailability of active compounds, as well as their application in the animal feed additive industry.

Review: Are we using probiotics correctly in post-weaning piglets? by Barba-Vidal, E., Martín-Orúe, S.M., and L. Castillejos 2018 Animal 12: 2489-2498
In Significant Impact Groups: Specific alternatives \ Pre-/probiotics; Feed / gut health
Species targeted: Pigs;
Age: Young;
Summary:
This review critically examines the use of probiotics in post-weaning piglets, focusing on challenge situations, and proposes potential strategies to increase consistency in probiotic effects. Given the current lack of reproducibility commonly described with probiotic use, this approach could have significant positive effects upon the efficacy of probiotic products and economic viability of the swine industry. Furthermore, it aims to be useful to swine nutritionists, researchers and the additive industry to critically consider their approach when developing or using probiotic strategies in weaning piglets.

Using probiotics to improve swine gut health and nutrient utilization by Liao, S.F., and M. Nyachoti 2017 Animal Nutrition Dec: 331–343
In Significant Impact Groups: Specific alternatives \ Pre-/probiotics; Feed / gut health
Species targeted: Pigs;
Age: Not stated;
Summary:
Beyond its physiological function as the alimentary canal for nutrient digestion and absorption, pig’s gastro-intestinal tract (GIT) is also one of the largest organs that helps animal’s immune function, because by nature the gut is animal’s first line of defense against the microbial pressure from its environment, especially the invasive pathogens from the GIT lumen. Activation of the GIT immune system incurs the direct cost of producing a diverse set of specialized immune cells and signaling molecules, as well as the losses in the efficiency of GIT digestive function. Therefore, only a healthy gut can lead to a healthy pig. And only a healthy pig can utilize dietary nutrients efficiently for tissue accretion, and lead to a better production performance and, thus, a higher return on investment for swine producers. This review paper aims to provide some much needed up-to-date knowledge and comprehensive references for swine nutritionists and producers to refer to before making prudent decisions and for scientists and researchers to develop better commercial products.

A review of the effects of dietary organic acids fed to swine by Suiryanrayna, M.V.A.N., and J.V. Ramana 2015 Journal of Animal Science and Biotechnology 6: 11-Jan
In Significant Impact Groups: Feed / gut health \ Feed additives and supplements; Specific alternatives
Species targeted: Pigs;
Age: Young;
Summary:
The weaning transition is a complex period during which the piglets have to cope up with abrupt separation from their mother, mixing with other litters in a usually new environment and turning over to a less digestible solid creep feed to highly digestible liquid milk. Early weaned piglets are (3–4 weeks age) exposed to stress with a reduced feed intake, little or no weight gain. This post weaning lag period is due to a limited digestive and absorptive capacity due to insufficient production of hydrochloric acid, pancreatic enzymes and sudden changes in feed consistency and intake. The aim of this review is to evaluate the response of weaned piglets, growing pigs and reproductive m sows to dietary organic acids as illustrated in terms of performance, i.e., growth rate, feed intake and feed utilization. In addition, reasons for varying responses to and possible modes of action of organic acids will be discussed.

Post weaning diarrhea in pigs: risk factors and non-colistin-based control strategies by Rhouma, M., Fairbrother, J.M., Beaudry, F., and A. Letellier 2017 Acta Veterinaria Scandinavica 59: 31

Age: Young;
Summary:
Post-weaning diarrhea (PWD) due to Escherichia coli is an economically important disease in pig production worldwide, affecting pigs during the first 2 weeks after weaning and characterized by sudden death or diarrhea, dehydration, and growth retardation in surviving piglets. Furthermore, many stress factors associated with the weaning period, such as removal from the sow, dietary changes, adapting to a new environment, mixing of pigs from different farms and histological changes in the small intestine, may negatively affect the response of immune system and lead to an intestinal gut dysfunction in pigs.

Species targeted: Pigs;
Age: Young;
Summary:
Diarrhea in piglets can be caused by several pathogenic agents, including Campylobacter spp., Clostridium perfringens, Escherichia coli, Salmonella spp., group A rotavirus (RV-A), coronaviruses (transmissible gastroenteritis virus—TGEV; porcine epidemic diarrhea virus—PEDV), as well as by nematode and protozoan parasites. However, most studies have focused on a few or only one agent and consequently our understanding of the relative importance of pathogens and other factors may have strong biases.

Age: Not stated;
Summary:
Concerns about the acquisition of antibiotic resistant genes in human and animal pathogens is one of the main public health issues. The problem of the emergence of resistant microorganisms such as Methicillin-resistant Staphylococcus aureus (MRSA) associated to livestock is closely linked to high use of antimicrobial agents in veterinary care, and international trade of food of animal origin which can encourage the spread of resistant strains. Drug-resistant bacteria may circulate in human and animal populations trough food, water and the environment, and its transmission is encouraged by trade, travel, human migration and transhumance

In Significant Impact Groups: Feed / gut health
Species targeted: Pigs;
Age: Young;
Summary:
The need for a reduction in the use of antibiotics in livestock to safeguard their efficacy requires the development of alternatives. In this line, the use of alternative by-products or ingredients, with functional properties brings the opportunity to improve pig health and thus, reduce medicalization. Therefore, in the present study, we aimed to evaluate the impact of an alternative feeding program based on unmedicalized diets formulated with fibrous by-products and functional feed ingredients on performance and fecal microbiota of young pigs compared to a common weaner diet supplemented with antibiotics. The alternative feeding program could anticipate the gut development of young piglets, which at the end of the nursery period presented a fecal microbiota more similar to that found in fattening animals. Moreover, piglets in the unmedicalized diets showed a trend to reduce the course of diarrhea immediately after weaning. The alternative feeding program showed, however, a reduced growth efficiency during the nursery period that needs to be discussed in the frame of the costs-benefits analysis of reducing antibiotics.

In Significant Impact Groups: Biosecurity \External biosecurity; Animals
Species targeted: Other;
Age: Not stated;
Summary:
Wild animals foraging in the human-influenced environment are colonized by bacteria with clinically important antibiotic resistance. The occurrence of such bacteria in wildlife is influenced by various biological, ecological, and geographical factors which have not yet been fully understood. More research focusing on the human-animal-environmental interface and using novel approaches is required to understand the role of wild animals in the transmission of antibiotic resistance and to assess potential risks for the public health.
