Saws, Drills and Hammers

Wait, what did I study again? Yes, you are still on the blog representing the master programme of animal science, haha. You may have read that I have been busy with preparing a preference test for chickens. Well, this is a big part of the preparations – the practical part – so to say. As the two sections of our testing pen should be as identical as possible, I am constructing smaller perches of which two should fit into one pen, instead of one large perch. After measuring, drawing and calculating, I’ve been spending many hours at the research facility sawing, drilling and hammering. Who would have thought this would be included in your masters degree? Not me! But I enjoy these kind of things a lot, and it’s a welcome change to sitting in class. Hopefully the chicken will be content with my handicrafts!

Any questions? Suggestions? Want to volunteer building perches? You’re always welcome to leave a reply.


GAP 21: Sheep in Sweden

GAP21 stands for Global Animal Production in the 21 Century. No animal production system is perfect. Each culture has their own traditions regarding animal husbandry. Every country faces their own challenges. Let me show you what I have seen and learned thus far: One photo at a time.

In Scandinavia, sheep production is strongly bound to the climate. However,
there are different types of production systems used. Timing of birth of the lambs
is regulated by the time of year breeding takes place. Depending on the moment
that lambs are ready for slaughter, it is either called spring, autumn or winter
production.  The impact of the type of production is huge, since lambs born before
late spring, will need to be kept indoors over winter. Not only does this mean that
more space is required in the barn, there are also higher costs of straw, hay and labour.
Yet, this production system is not uncommon. The lambs on the photo had spent
their lives indoor thus far; their first day outside was a joy to watch!


Preparing a Preference Test

Since a few months I have been doing behavioural observations of the chickens as part of my degree project. However, soon I will start with the second part of this research project as well; the preference test. The idea is not to difficult to understand. A certain space is divided into two or multiple areas with one same variable that is different for each section. Then the animals are put in the space with the ability to roam around freely, and their locations and behaviours are scored. In the end you can see if the animals seem to prefer one section over another or whether their behaviour is different in one of the sections. To not have any bias of the results, the different sections should be as identical as possible.

In our case the variable is the wavelength of light. The test pen will be divided into two zones with different types of lighting, which are separated from each other by black plastic. The animals involved in the preference tests are the same chickens from the behavioural observations. I will be the observer of the behaviour and location of the chickens. So far it sounds pretty straight forward, right? Now have a look at the model I made of our pen:

Bike Life

“The many bike lanes that run through the whole city make biking a safe and efficient option.”

As a student it’s probably the first thing you should buy once you’ve moved into Uppsala: A bike. Uppsala is known in Sweden as ‘The bike town’, and this nickname did not come out of the blue. The many bike lanes that run through the whole city make biking a safe and efficient option. To me, coming from the Netherlands, the possibilities of biking everywhere and the town including a proper biking infrastructure did not seem very special at first. But the more I talk with both Swedish and international students, the more I realise how uncommon such a situation is. And very, very well appreciated.

Some things were new to me though. For example, the mountains. All my non-Dutch friends tell me they are ‘just hills’, but these steep bastards are definitely mountains to me. Though Uppsala is rather flat you still feel whether you are biking uphill or downhill and there are for sure streets almost every city cyclist tends to avoid because they are quite steep. Another new aspect are the relatively large distances. I must admit, not everybody is as determined to bike as me and many of my friends buy monthly bus tickets, especially in wintertime. However there is a large share of students that bikes from town to university on a daily basis.

Most bike lanes are shared with pedestrians. And in some areas
paths are even shared with horses! The split on the sign marks
where exactly one is supposed to make use of the track.

From my house to campus is a bit more than 7 km long and takes about half an hour. However, the popular student area of Flogsta is also located about 3 km from the city centre, which takes up to 15 minutes, depending on where in town you have to be. This means that on an average day on which you go to SLU during the day and meet up with friends at one of the nation pubs in the night, you will bike one and a half hour. That does not yet include any additional biking for doing groceries or going to the gym. However, my cycling life reached a new level now I have to visit Lövsta on a regular basis because of my degree project. From my house to Lövsta is over 16 km, one way. Which takes a bit more than an hour, meaning after coming home from my research chicks, I’ve already spend two to two and a half hours on bike. Luckily the route is quite beautiful and I am sure it keeps me fit. Or at least, I’d like to believe that!

Are you coming to Uppsala for (part of) your studies? The best advice I can give you is to start saving up some money for a nice, proper bike. You can thank me later 😉



Exams & Evaluation

Last week our housing course came to and end. Our final exam was an essay type home-exam. I’ve written before about the variety of examination types here at SLU. I still found it a bit hard to prepare for such an exam, as it’s not a method I am used to. However, I think the exam touched upon all aspects of the course and must have given a good overview of our obtained skills. The housing course included a lot of physics and engineering, therefore I think that this type of exam was perhaps more useful than a traditional exam. The calculations were rather challenging, but let’s hope for the best.

“SLU puts a lot of emphasis on course evaluations, as they are of use to improve the quality of education.”

Now it’s time for the course evaluation. After each course there is usually a moment of evaluation both in class, as well as online. SLU puts a lot of emphasis on these evaluations, as they are of use to improve the quality of education. This time I have volunteered to be the course representative, which will be my first time. The course representative plays an important role in the course evaluation. As a representative you are supposed to discuss with your classmates about possible improvements, but also to scan through the evaluations and highlight the most important suggestions. The final summary will be discussed with the course leader and hopefully lead to future improvements. The grade out of the scoring by the students will become available on the SLU studentweb. When you are looking into which courses to pick for the next semester, you can find these scores of the courses from previous years, which may be helpful to make a decision.

Do you have any more questions about the examination or course evaluation? You’re always welcome to comment or leave a question in a reply below.


Vår i Uppsala

Do you know this feeling, when the sunlight touches your face and you realize how much you missed her? Sunshine, it’s like liquid happiness. Especially after these long, dark Scandinavian winters. Last week started with days of snowfall, yet soon it was replaced with bright, sunny days. The ice melted away, the gravel is being brushed off from the pathways. My bike is not wearing his winter tires any longer. The amount of people running outdoors is tremendous. You can feel the tension for the Valborg festival starting to build up. And to top it all of, this weekend we will get the best present you can imagine: Another hour of daylight, hurra!

Beautiful Uppsala, I took the photo last week. In the middle you see the famous Domkyrkan.


Excursion to an organic dairy farm

Waiting in front of the barn, opposite the summer pastures, now covered in snow

There is one more excursion from the animal housing course I’d like to tell you more about. The same day as visiting the active horse stable, we went to see an organic dairy farm. As we had already been looking at a couple of dairy stables, such as the modern loose housing and the traditional tie stalls at Jälla an the very large facility at Lövsta, we could make some comparisons. Plus, this was the first organic system we were going to see since the course had started. The farm is operated according to the standards of KRAV, which I explained something about in the previous post about our project work.

After we had changed into our protective wear we were warmly welcomed by the dairy farmer. He explained a bit about his farm before giving us a guided tour over his premises. He showed us his milking robot, the main herd, young stock, calves and pregnant cows. We had a closer look at his manure management and the types of flooring he used. There were generally large differences between the buildings but all of them were naturally ventilated. Which I think was quite fascinating seen the cold Scandinavian climate, but his Swedish red cows seemed to cope well with it. After the tour we had the possibility to go and look around a bit more for ourselves.

The indoor housing of organic and conventional dairy cows is not that different. I’d say that the biggest differences concern the feed and pasture management, though in Sweden grazing is obligatory for conventional dairy as well. We were lucky to see a calf that had just been born, being licked dry by her mother. We asked the farmer for how long calves are required to be with their mothers, and he explained that it should be at least for 24 hours. He also told us that it used to be longer, but that KRAV has changed this quite recently in their standard. He expressed how pleased he is with this, since in his experience it is less stressful for the mother and calf to be separated after 24 hours than after three days. This information resulted spontaneously in a very interesting discussion about the different rules and experiences concerning calf weaning between the students from our class. It’s a hot topic in many countries at the moment and the opinions on it vary strongly.

Before we went back to the bus we continued to talk for a little while with the farmer. I was curious about what he’d like to improve most and he told me that he’d like to change the housing for the calves. Right now part of the calves are housed in what used to be a tie-stall stable and the ventilation is not optimal. He had noted that the calves in this building perform less well than his calves in the outdoor iglos. A direct example of the interaction between animal and environment.

“Should we build for less durability?”

Our course leader, Stefan Gunnarsson, was wondering what the farmer would like to see from us in our future career as ‘potential farm designers and advisors’. He answered: “Beautiful buildings, easy to work in and should be good for the animals too. Simple.” However, he took me by surprise when he continued about durability. He wondered if we were making buildings maybe too durable? He explained that the materials we use now, result in farm buildings that can live for up to perhaps a hundred years. But after about twenty years a building is maybe not ‘so modern anymore’, and might not fulfil the latest requirements. This results in empty farm buildings – a waste according to the farmer. Should we build for less durability? Some food for thought.

Any thoughts on this topic, or some quiestions? Feel free to reply below.


Project-work: Planning & design

With the final exam coming up this Monday the housing course is soon coming to an end. It’s feels like it was yesterday when we started! Last week was fully dedicated to our project-work and the presentations of it. We have been working for several weeks in small groups on the task to plan and design a farm building. As each group had been given a different animal species to work with, the results were very diverse. This made it quite exciting to see all the presentations, since everybody had been facing different challenges. The project-work was focused on following the Swedish guidelines, but paid attention to the international perspective as well.

“For laying hens the differences between KRAV and EU organic are not as big as for example in pig production.”

Our group had the task to design a housing facility for laying hens. We were given the choice between conventional farming or organic, and we chose the latter. In Sweden most of the organic farming is according to the standards of KRAV, which often has additional requirements concerning animal welfare and environment than the EU organic standard. As we were curious to these differences we chose to plan our farm as if it were going to be KRAV certified. Surprisingly, we found that for laying hens the differences between KRAV and EU organic are not as big as for example in pig production.

“The project faced a wide range of aspects to consider, such as biosecurity, ventilation, heat balance, manure management and fire protection.”

The project faced a wide range of aspects to consider, such as biosecurity, ventilation, heat balance, manure management and fire protection. I liked it that we were asked to give scientific support behind our decisions, but it also made the project very time consuming. It was absolutely useful that we had been on so many excursions(to Jällaskolan, Lövsta and Marma Torp) looking at these details, but also the experience from the workshop we had earlier in the course, helped a lot to be able to do the necessary calculations for our project. All together I think we all learned a great deal during the project, but are happy that it’s finished now so we can focus fully on preparing for the exam 🙂

Do you have any questions? Feel free to ask.


GAP21: Intensive dairy in Denmark

GAP21 stands for Global Animal Production in the 21 Century. No animal production system is perfect. Each culture has their own traditions regarding animal husbandry. Every country faces their own challenges. Let me show you what I have seen and learned thus far: One photo at a time.

Adorable, those young dairy calves. With their big eyes and wet noses, trying to lick you when you approach. In Denmark many dairy farms are so big that there are always some new born calves around. Farmers have mixed feelings when a new calf is born. Is it a cow or a bull calf? It’s a hard day, when mainly males are born. In Denmark it is not uncommon that the bull calves are shot, even before it had it’s first drink. All over the world farmers with specialized dairy systems face the same struggle: What to do with the bull calves? In some countries there are little issues raising these young bulls, but in Denmark that is not the case. ‘I wish I could let them live, but I will loose a lot of money on feeding it and in the end I can not sell it for a reasonable price’, a farmer explained. So this picture you see, it’s females only; their brothers never made it to the young stock stable. It was taken in 2012, but I am afraid there is no reason to believe the faith of bull calves has changed yet. 


How Sweden made me a feminist.

Feminism. What was your first association to this word? To me for a long time when thinking about feminism those images of angry women popped up in my head. Those women with big bushes of hair under their armpits who’d put out bras on the streets to protest. I had seen pictures of them, in my history books. What would you need feminism these days for, I wondered? Correct or not, growing up in The Netherlands I was never under the impression of unequal opportunities for men or women. We could all go to school, choose career paths we found interesting and would be allowed to vote one day, right?

“”You fucking WOMEN, you are so slow!”, he would rage at me and – by the way – at his wife.”

In the years that followed I started noting some ‘small things‘ that seemed a little odd, but I never paid too much attention to. No, the real eye opener came, when I went on a working holiday in New Zealand. When I got accepted for an amazing horse job I was absolutely delighted. Though soon enough I realized that the guy I worked for treated women without any respect. I had been shouted at before, but never because of my gender. “You fucking WOMEN, you are so slow!”, he would rage at me and – by the way – at his wife. I did not stay long. Nor did I in the next two horse stables, where a similar situation simply seemed to reoccur. However something had awakened in me, and it never went back to sleep.

“Is it normal that men I respect and know well, do not want their girlfriends to be seen in a public sauna?”

Back in the Netherlands I started looking at things in a different perspective. Was it really that more equal, I wondered? Thoughts I had not given much attention to before, kept popping into my head. About teachers who would never take me serious in class, so I’d ask my male classmates to ask the question for me. Or why had it automatically been assumed I would become a cashier and not a shelf stacker, when I applied for my first job at the local supermarket? How about all these sexist jokes my friends from uni seemed to consider very funny, were they really that innocent? Is it normal that men I respect and know well, do not want their girlfriends to be seen in a public sauna?

Toilet signs at SLU are gender neutral

I didn’t stay for a long time at home, as my master studies in Sweden followed shortly after my gap year. I am not saying Sweden is perfect in terms of gender equality, but it comes pretty damn close. Construction workers apologizing for the inconvenience, instead off making sexist jokes while a woman passes by. Fathers having the same, very long, paternity leave as mothers when their babies are born. Boys working as cashiers, while girls are stocking shelves. I’ll never forget the first guy that introduced himself to me as a feminist – I almost spilled my drink back then, but I got used to it now. Did you know that they even introduced a new word to their language, to express themselves without indicating someone’s gender?

“An equality that – they are aware of very well – has not been reached yet.”

Most importantly, people find it simply normal to talk about how to overcome the gender pay gap, the lack of women leaders or the stereotype that sensitive men are seen as weak. Here, feminists are not put in a corner as attention-seeking man haters, feminists are those people (let’s put no gender discrimination of the subject here 😉 ) that speak up for gender equality. An equality that – they are aware of very well – has not been reached yet. An inequality that I learned not to overlook any longer and am now willing to fight for.  Tack så mycket, Sweden, for changing me into a feminist.

Rest me to say: Happy International Women’s Day 😀
