Case 4; milk
10 important questions on Case 4; milk
What can you tell me about the oestrous cycle?
- when initiated, the cow is ready to be inseminated around the time of ovulation
- cycle can be divided into a luteal and a follicular phase
What can you tell me about the luteal phase?
- starts with ovulation and last until the regression of the corpus luteum
What can you tell me about the follicular phase?
- defined as the period between the regression of a corpus luteum and ovulation
- at the end of follicular phase, the cow will be in oestrus
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
What can you tell me about the corpus luteum?
- it produces progesterone (P4), which functions to maintain an appropriate uterine endometrium for a potential embryo to develop in. The P4 concentrations increase during the luteal phase
- no fertilization: the corpus luteum will degenerate and stop producing P4. This allows another follicle to grow and rupture from an ovary under the influence of oestrogen (E2) during the follicular phase -> marks the next ovulation
In this schematic overview of the mammary gland, the organisation and its functioning are depicted. Name what happens at each number
2. These impulses stimulate nerves in the paracentricular nuclei. This causes the posterior lobe of the pituitary to release oxytocin
3. This oxytocin is delivered to the mammary gland through the blood
4. Which causes the myoepithelial cells around the alveolus to contract
5. this contraction will release milk out of each individual; alveolus into small ducts and then into larger ducts. When the milk enters the larger ducts and the gland cistern, the neonate can drink from it (or be removed via milking the cow)
What can you tell me about the dry period of a cow?
- during this period, there is time for the mammary tissue of the dairy cow to involute
- this involution reflects the recovery and development of new epithelial cells
-> a dry period positively contributes to the proliferation of mammary gland epithelial cells
- for subsequent lactation, this proliferation contributes to max milk, protein and fat yields
What can you tell me about Negative energy balance (NEB)?
- while the dry matter intake is decreased in the transition period, the milk production increases during early lactation, resulting inn an energy deficit
- if NEB persist cerrverrely, it can affect rreprroductivity and immunity, resulting in an increased culling rate
What are the negative effects of shortening or omitting the dry period?
2. Difference in milk component levels
3. The production loss, with 0 days dry period, is lower for multiparous cows compared to primiparous cows. The production loss, with shorter dry period, is lower for primiparous cows
What can you tell me about ketosis in cows?
- A negative energy balance is a result of too little energy intake to account for the energy needed for milk production
- results in low blood glucose levels and high levels of ketone bodies in the blood -> These ketone bodies can leak into the urine or milk, which will lead to loss of milk quality
- cows with energy shortage in their feed, will mobilise fat from their body, which results in a higher fat level in the milk they produce
- cows suffering will have decreased appetite
What can you tell me about milk fever in cows?
- when this happens, calcium from the bones is depleted to replete the levels in the blood -> these processes take some time, which leads to a calcium shortage
