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 Swedish dairy industry has made significant improvements in welfare, feeding, disease control and management. However, diagnosis and prevention of a very common metabolic disorder, subacute ruminal acidosis (SARA), remains a challenge. Even in well-managed dairy herds 11 to 26% of SARA cases …

Forage crops occupy a dominant part of the agricultural landscape in Sweden and form the basis of ruminant diets. Farmers aim to maximize harvest yield while maintaining a high level of forage quality. The proposed project is a partnership between SLU and Dataväxt, and aims to develop a decision …

The goal with this project is to increase the profitability and production efficiency on Swedish dairy farms by renewing
the genetic evaluation of the breeding value of temperament in dairy cows. We want to investigate if automatic
recordings of behaviour using SLU Gigacow on farm level can improve …

To grow with reduced use of glyphosate is of great concern driven by the requirements for integrated pest management, the risk of herbicide resistance and a potential coming ban on glyphosate. It requires balancing between environmental effects and impact on yield and economy. The project's goal is …

In Sweden, there is both a great potential and a great need for increased cultivation and processing of plant-based foods from alternative protein crops. The overall aim of the project is therefore to increase the production of Swedish plant proteins for food. The objective is to identify …

We need to remediate the capacity of agricultural landscapes to retain water, nutrients and sediments to make them
more resilient to the increasing frequency of flooding, drought and pollution expected with the climate change. It can
be done by remediating existing narrow ditches into ditches with …

It is well known that storage of animal manure and digestate causes emissions of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). A crust on liquid manure acts both as a physical barrier for NH3 and as a biofilter that oxidize CH4 and NH3. However, N2O can be formed in some crusts, and there …

Even if Sweden is historically regarded as a water-affluent country, lately sustainable water use and water circularity have become topics of high concern. Irrigation is dependent on high quality water resources, and the need for accessible water resources becomes stronger under exceptionally dry …

An improved strategy for agricultural drainage is important for both economic and environmental reasons. There are indications on environmental benefits of a good drainage but lack of studies that directly shows this. The aim of the project is to develop a basis for design recommendations for new …

The use of safely reclaimed water for agriculture irrigation is a promising solution to address water shortages, especially on Gotland. One primary concern is the introduction of organic micropollutants (OMPs), such as pharmaceuticals and other chemicals, into the agricultural ecosystem and food …
