Summary:
Successful fattening of pigs and animal welfare – Andreas von Felde believes that these objectives are not excluded. This farmer from northern Germany grows rye and uses it as feed. He says he needs less fertilizer.
“Rye has a large amount of carbohydrates that are not digested in the small intestine. In short, they feed microorganisms in the small intestine and microflora. ” This produces butyric acid, which has a positive influence on the behavior of animals when they are fattened. Butyric acid is also very effective in killing bacteria such as salmonella.

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Pigs;
Age: Adult; Young;
Summary:
The development of both innate and adaptive immunity at the mucosal surface is critical in preventing the potential harmful effects of intestinal pathogenic agents. Strategies aiming at stimulating natural host defences through the use of substances able to modulate immune functions have gained increasing interest in animal research, and different bioactive components a priori sharing those properties have been the subject of in vivo nutritional investigations in pig. Among these, yeast derivates (b-glucans and mannans) are able to interact with immune cells, particularly phagocytic cells. This review also highlights the limitations of some of the published in vivo studies on the immunomodulatory activity of certain feed additives. Among those, the lack of standardisation of extracts and the heterogeneity of piglet-rearing conditions (e.g. exposure to pathogens) are likely the most limiting.

368 Research report – De Grande – 2020 – Dietary zinc source affects performance and intestinal health in broilers

In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Poultry;
Age: Young;
Summary:
In supplementation of zinc as a complex with amino acids has larger effects on gut health of broilers compared to an inorganic source such as ZnSO4. Especially in periods of stress larger effects are observed regarding feed conversion, gut morphology and meat quality. An optimal gut health is crucial for healthy growth of broilers. Several factors such as high environmental temperatures, put more stress on the health and integrity of the gut. Supplementation of the Zinc can be of support. Zinc is an essential trace element that is known to be part of several biological processes. Still, its supplementation can be done with various sources. This study investigated whether the source of Zinc, either organic or inorganic, has an effect on the gut morphology, technical performance and meat quality of broilers. The best results were attained when supplementing in feed with an organic zinc-amino acid complex, especially in stressful periods.

In Significant Impact Groups: Feed / gut health
Species targeted: Pigs;
Age: Young;
Summary:
The establishment and maintenance of a beneficial gut microbiota early in life is crucial in pigs. The intestinal microbiota is known to play major roles in the development of immune system and the overall health of piglets. Piglets are exposed to a number of stressors during the weaning transition. This review provides a general overview of recent studies on effects on weaned piglet gut microbiota. Several factors that influence the gut microbiota are described: diet and diet change, probiotics, prebiotic and synbiotics, antibiotic, host genetic, and the possible links between the intestinal microbiota composition of piglets and its association with growth performance and health.

Species targeted: Poultry;
Age: Young;
Summary:
This experiment showed promising results in the recovery of broiler chicks after a challenge with mild coccidiosis infection (E. Tenella). The chicks were fed a feed containing an additive that boosted their immuneresponse to the parasite and an additional antioxidant to mitigate tissue damage to the gut from an excessive immune response. Both the chicks on the control diet (without the new additives) and the chicks receiving the treatment were challenged with a mild coccidiosis infection and did not differ in overall performance. However, the chicks on the treatment diet showed faster recovery and better daily gain instantely after the infection with the parasite. This led the researchers to believe that chicks under a more severe infection could benefit more from this innovative dietary supportive treatment.

Species targeted: Beef;
Age: Young; Adult;
Summary:
A scoping review (systematically map the literature with regard to the extent, range, and nature of the existing research) on non-antibiotic interventions in the form of products or management practices that could potentially reduce the need for antibiotics in beef and veal animals living under intensive production conditions was conducted. The objectives of this review were 3-fold: first, to examine and describe the range and nature of research on nonantibiotic approaches that may ultimately reduce the need for medically important antibiotics to prevent, control, or treat illnesses in beef and veal production; second, to identify areas where the available literature may support systematic reviews that could summarize the effect of specific non-antibiotic approaches within the broader topic area; and third, to identify knowledge gaps where additional primary research might provide valuable insight into the effectiveness of different specific nonantibiotic approaches. The four most frequent interventions included non-antibiotic feed additives, vaccinations, breed type, and feed type.

Species targeted: Pigs;
Age: Young;
Summary:
With the rapidly increasing knowledge of the role of the gut microbiome in diverse aspects of human and veterinary health, antibody-type drug-mediated methodology to specifically interfere with the microbiome or host factors in the gut is needed. Oral antibodies that interfere with gastrointestinal targets and can be manufactured at scale are needed. This paper shows that a single-gene-encoded monomeric immunoglobulin A (IgA)-like antibody, composed of camelid variable single domain antibodies (VHH) fused to IgA Fc (mVHH-IgA), prevents infection by enterotoxigenic Escherichia coli (F4-ETEC) in piglets. The mVHH-IgA can be produced in soybean seeds or secreted from the yeast Pichia pastoris, freeze- or spraydried and orally delivered within food. Future farm-based trials en route translation of this application, will enable impact assessment of mVHH-IgA on F4-ETEC-caused diarrhea and weight loss.

In Significant Impact Groups: Pathogen management
Species targeted: Dairy;
Age: Young;
Summary:
The aim of this study was to develop and validate 2 protocols (for use on-farm and at a central location) for the reduction of Mycobacterium avium ssp. Paratuberculosis (MAP) in colostrum while preserving beneficial immunoglobulins (IgG). The on-farm protocol was based on curdling of the colostrum, where the IgG remain in the whey and the MAP bacteria are trapped in the curd. The semi-industrial protocol was based on centrifugation, which causes MAP to precipitate, while the IgG remain in the supernatant. The effect of the colostrum treatment on the nutritional value and palatability of the colostrum and the IgG transfer was assessed in calves. The treated colostrum had no negative impact on animal health, IgG uptake in the blood serum, milk, or forage uptake. Two protocols to reduce MAP in colostrum (for use on-farm or at a central location) were developed and both methods preserve the vital IgG.

Species targeted: Poultry;
Age: Young; Adult;
Summary:
After the ban of antibiotic growth promoters (AGP) in the EU many alternative substances have been investigated for their potential to replace AGPs. Phytobiotics are discussed as one promising alternative due because they contain many pharmacologically active compounds. A huge number of studies have confirmed a wide range of activities of phytobiotics in poultry nutrition like stimulation of feed intake, antimicrobial, coccidiostatic and anthelmintic effects. The present paper gives a short review on the characteristics of phytobiotics, on the potential mode of action and on the effects of phytobiotics in diets on performance, carcass and meat quality and health status in broilers. Furthermore, it addresses possible safety concerns involving application of phytobiotics.

In Significant Impact Groups: Feed / gut health \ Feeding management
Species targeted: Poultry;
Age: Young; Adult;
Summary:
The three most important legs of an effective intestinal management program include: “seeding” the gut with favourable organisms, “feeding” the favourable organisms and “weeding” out the unfavourable organisms. This involves applying a probiotic/competitive exclusion product as soon after hatch as possible. Adding a suitable organic acid via the drinking water to increasing its concentration in the small intestine and enhance the capacity of the favourable organisms to colonize and rapidly dominate the microbial community of the small intestine. Blocking the attachment mechanism of unfavourable organisms with a type-1 fimbria blocker and thereby reducing their capacity to compete with the favourable organisms in the gut.
