Zinkoxid (ZnO) in feed prevents post weaning diarrhoea (PWD) and mortality in weaned piglets but, for environmental reasons, ZnO will be banned in the EU in 2022 despite that there remain herds that are dependent on the use of ZnO (or antibiotics) at weaning.
By metagenomic analysis (sequencing the 16S-gene), we aim to develop an objective method to describe the stability of the intestinal microbiota. The aim thereafter will be to identify the efficacy of measures undertaken to enable weaning in absence of PWD. Such measures include management strategies, feeding strategies and feed recipes, which will be documented in 60 herds that phase out the use of ZnO ahead of 2022. Measures undertaken that appear to be successful in preventing PWD and stabilise the intestinal microbiota will be defined and documented. In the next step, information about such measures of success will be described and presented to stakeholders ahead of the ban of ZnO in 2022.
Zinkoxid (ZnO) i avvänjningsfoder minskar diarré och dödlighet bland smågrisar, men ZnO kommer av miljöskäl att förbjudas 2022 trots att det finns besättningar som är beroende av ZnO (eller antibiotika) vid avvänjningen.
Med metagenomik (sekvensering av delar av 16S-genen) avser vi att utveckla en effektiv metod att objektivt bedöma tarmflorans stabilitet. Målsättningen därefter är att identifiera åtgärder som optimerar stabiliteten i tarmfloran kring avvänjning. Bland sådana åtgärder ingår managementsstrategier, utfodringsstrategier och foderrecept, vilka kommer att följas i 60 besättningar som frivilligt fasar ut ZnO-användningen i förtid.
Åtgärder som visar sig effektiva vad gäller förebyggande av avvänjningsdiarré och stabilisering av tarmfloran i samband med avvänjning kommer därigenom att identifieras och dokumenteras. I ett nästa steg kommer information om sådana positiva åtgärder/insatser att spridas till andra lantbrukare.

The ability of milk to coagulate is crucial for cheese production. We have previously shown high occurrence of non-coagulating milk from Swedish Red Dairy cattle and identified milk proteins as potential markers for this undesirable trait. In this project we will increase the understanding of the …

Cereal production is limited by many different factors. Leaf diseases are often well known, while diseases on roots are more difficult to identify. Root diseases are often caused by oomycetes, fungus-like microorganisms that live for years in soil and on old root debris, parasitizing the roots of …
