370 Research paper – Du – 2020 – Antimicrobial Effect of Zophobas morio Hemolymph against Bovine Mastitis Pathogens

In Significant Impact Groups: Specific alternatives
Species targeted: Dairy;
Age: Adult;
Summary:
In the present study, we showed the protective effect of Zophobas morio (Z. morio) hemolymph on bovine mammary epithelial cells against bacterial infection. Z. morio hemolymph directly kills both Gram-positive and Gram-negative bacteria through membrane permeation and prevents the adhesion of E. coli or the clinically isolated S. simulans strain to bovine mammary epithelial (MAC-T) cells. In addition, Z. morio hemolymph downregulates the expression of nucleotide-binding oligomerization domain (NOD)-like receptor family member pyrin domain-containing protein 3 (NLRP3), caspase-1, and NLRP6, as well as inhibits the secretion of interleukin-1 beta (IL-1 beta) and IL-18, which attenuates E. coli or S. simulans-induced pyroptosis. Overall, our results suggest the potential role of Z. morio hemolymph as a novel therapeutic candidate for bovine mastitis.

369 Research paper – Cheng – 2020 – Bovine mastitis_ risk factors therapeutic strategies and alternative treatments — A review

Specific alternatives \ Other
Species targeted: Dairy;
Age: Adult;
Summary:
The etiological agents of Bovine mastitis include a variety of gram-positive and gram-negative bacteria, and can be either contagious (e.g., Staphylococcus aureus, Streptococcus agalactiae, Mycoplasma spp.) or environmental (e.g., Escherichia coli, Enterococcus spp., coagulase-negative Staphylococcus, Streptococcus uberis). The extensive use of antibiotics increased concerns about emergence of antibiotic-resistant pathogens and that led the dairy industries to reduce the use of antibiotics. This review provides an overview of bovine mastitis in the aspects of risk factors, control and treatments, and emerging therapeutic alternatives in the control of bovine mastitis.

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.

366 Research paper – Guevarra – 2019 – Piglet gut microbial shifts early in life_ causes and effects

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.

365 Research paper – Campbell – 2019 – A review of environmental enrichment for laying hens during rearing in relation to their behavioral and physiological development

Housing and welfare \ Enrichment
Species targeted: Poultry;
Age: Young;
Summary:
Recently, there has been increasing focus on the impacts of the rearing environment on long-term behavior, health, and welfare of layers. Enriching the rearing environments with physical, sensory, and stimulatory additions can help to maximize the bird’s developmental potential. This review describes the available literature regarding enrichments provided during rearing and the subsequent impact they have on different aspects of behavioral and physiological development, including identifying the ways enrichments could have biological impact. The behaviour of the birds and their needs (dustbathing, perching, foraging) will improve their well-being and will probably result in a bird that is better able to respond to infections. But what exactly the mechanism behind the positive impact of enriched housing environments is on immunocompetence are currently poorly understood due to limited research in this area. There is a need to identify practical cost-effective enrichments that producers would use on-farm and to have commercial validation of positive impacts on aspects of behavior and biology.

364 Industry Innovation – LalFilm PRO by by Lallemand

In Significant Impact Groups: Pathogen management \ Biosecurity
Species targeted: Pigs; Poultry; Other;
Age: Different for different species;
Summary:
All microbial species can be biofilmogenic under certain stress conditions, nutrient concentration, colony size and degree of confinement. The exchange of information and gene expressions that characterize the biofilm make it an enemy to be fought as part of the fight against antibiotic resistance. During a webinar organised by Lallemand and Unitec, a method to combat the formation of pathogenic biofilm was presented, exploiting the antagonism between bacteria. LalFilmPRO, Lallemand’s apatogenic biofilm, can be used to reverse the paradigm, using the same weapons as bacteria to extend the hygiene protocol. The exclusive technology is based on the use of specific bacterial strains, with antagonistic efficacy and high adherence power. Bacterial strains have been selected to colonise an environment quickly and uniformly, which can inhibit and antagonise the growth of other species.

362 ToolsChecklists – The correct use of antibiotics in lambs and goat-kids_ Five key points for greater serenity by Idele

In Significant Impact Groups: Prudent use AB
Species targeted: Goat; Sheep;
Age:
Summary:
Reasoned and targeted use of antibiotics in lambs and kids follows a set of prescription and administration rules. A set of practical measures are recalled in this booklet. The rearing of young animals, whether kids or lambs, is based on a set of preventive measures to limit the occurrence of infections and their spread within the herd. Surveillance and care are therefore required from a very young age. Whereas diseases occur and after diagnosis, antibiotic treatment may be necessary.

361 ToolsChecklists – Antibiotics in goats_ essential for group pathologies while focusing on prevention by Idele

In Significant Impact Groups: Prudent use AB
Species targeted: Goat;
Age:
Summary:
A survey was carried out among 46 goat farmers to better understand their actions in the event of pathologies in goats and kids, regarding both the use of antibiotics and preventive management. When asked about their practices of using antibiotics in male or female goat kids, the farmers expressed the importance of surveillance and prevention. Challenged with the health risks encountered in young animals, they are attentive to the first signs of disease in order to react as quickly as possible and as closely as possible to the needs of the animals. The survey reported the implemented preventive methods, particularly about feeding and housing. The farming practices most commonly used to reduce the use of antibiotics in kids in the farms are :• Surveillance and care of the animals;• Early feeding of colostrum in sufficient quantity and quality, if necessary after thermisation;• The respect of feed requirements and feed transitions;• Good environmental conditions.
