Our research and teaching in ruminant nutrition and management includes nutrient metabolism, feeding, lactation, growth, behavior and housing issues. We focus on animal production and welfare and on quality of the products. The impact ruminant production has on the global environment has become an important part of our research. We have a large international network, within EU as well as worldwide.
In this three year long project, “The role of small-scale dairy cattle production in a sustainable and robust Swedish food supply”, we will map small-scale dairy herds in Sweden, and identify opportunities and obstacles for these herds to continuing producing sustainable dairy products in the future.
Digital dermatitis is a leading cause of lameness in dairy cattle, it is an animal welfare problem and leads to economic losses for the farmers. The etiology of the disease is still under debate.
Why does a dairy cow stay in her herd for such a short time? There is evidence that we place too much value on heifers. This project will develop an objective method for comparing cows and heifers.
Can the calf be together with the cow in a system with automatic milking? How does it affect milk yield and calf growth, health and fertility? In this research project, we study how calves can be integrated into such care systems.
Could impaired nutritional quality from delayed harvest of ley be counteracted by increasing the stubble height drastically and how would the total annual yield and quality then be affected?
This project will investigate the most economical and sustainable way of achieving less methane (CH4) from Swedish dairy production by composing low-emitting diets based on resources that cannot be directly utilized as food for humans.
This project aims to improve feed efficiency (FE) in dairy production by introducing new technology and digitalization (analysis of large data) and thereby develop new practical methods to include FE in dairy cattle genetic improvement, feeding and managements. The results of the project will significantly improve sustainability, profitability and decrease the environmental footprint of the value chain. We will evaluate modern and highly accurate on-line technologies for determining gas exchanges and FE of dairy cows.
The environmental impact of dairy cows (i.e. ruminants) has received a lot of attention from society and the scientific community, primarily focusing on strategies to reduce greenhouse gas emissions. The ruminants account for a significant proportion of methane emissions due to their enteric fermentation.
Ruminant livestock account for about half of the total greenhouse gas production in agriculture, where a large proportion of the emissions come from their digestion (enteric fermentation). Policies can be combined with information to consumers and investments in research to achieve climate and environmental goals . In the dairy industry, it is desired to produce milk with zero climate footprint, for example by increasing the carbon storage on farms, reducing the consumption of fossil fuels, increasing the biodiversity and using feed with as little climate impact as possible.
The objective of this project is to investigate the hypothesis that methane production could be further reduced from stored manure in dairy cows supplemented with Asparagopsis taxiformis.
Grazing can be a cheap way of feeding and, as the growing season gets longer, the possibility for increased use of this resource in northern areas is improving. There are however not many studies or data on grazing for dairy cows in northern Sweden.
The taste and smell of milk can sometimes be disrupted. One of the problems is when the milk has the scent and taste of blueberries. This can affect the quality of an entire milk silo at the dairy and the quality of the products made of it.
The general objective of this project is to enhance food security in Tanzania through improved rangeland and livestock management practices in miombo woodlands.
It is only when the cow has calved and starts producing milk that she gives an income to the milk producer and it is after the second lactation the income covers the cow's rearing costs.
Is it possible to keep dairy cows and their calves together in automatic milking systems? What are the effects on milk yield, calf growth, health and fertility? In this research project, we study how calves can be integrated into such systems.
The project investigates the biological conditions for separating a ley crop into two vertical strata fractions with different nutritional quality at mowing.
The aim of the project is to provide solutions for using unprocessed or nutritionally upgraded forest by-products as ruminant feed during forage shortage crises.
The overall objective of this project is to minimize the need for human-edible feed in dairy production and at the same time reduce enteric methane emission, with maintained good animal health and performance.
The aim of the project is to investigate how much extensive mechanical processing of silage can increase the forage intake in dairy cows and hereby reduce the requirement for concentrates.
The aim is to improve milking technology and milking routines to ensure that the udder is emptied as well as possible with good udder health and animal welfare.
The purpose of the project is to investigate whether cows who have the capacity to consume large amounts of roughage have different microflora in the rumen than low-capacity cows, and if the composition of the microorganisms and methane formation is associated with the passage rate.
The goal with this project was to make it possible for Swedish dairy farms to replace imported, soy based protein feed with on farm processed concentrate based on home-grown or regionally grown Swedish protein sources as field beans, peas and rapeseed.
In this European project we will study animal health and welfare, milk quality, environmental impacts etc in farms that use compost pack bedding and “cow gardens” in their barns for dairy cows.
The main objective of the project is to develop improved prediction methods of mastitis in dairy cows. This will be achieved by combining state-of-the-art mathematical / statistical methods with access to large amounts of online data.
The research at the Beijer Laboratory for Animal Science (BLAS) aims to make better use of data automatically collected at high-tech farms so that management and breeding of future generations of dairy cows may be as efficient as possible.
There are several projects going on in the area. One aim is to study the quality and microflora of northern Swedish milk at farm and dairy level, and the impact of this on maturing time and sensoric traits of long-ripened cheese.
