A1 Flashcards
How long is the period of a newborn and suckling piglet?
Suckling last 28 days
Weaning is done from week 4-8
BW at birth:
1-2 kg
Which age and weight are the piglets weaned?
7-9 kg
at day 28
What is the optimal weight gain for a piglet?
It should be doubled each weight until it reaches 3 weeks
How is the heat regulation of piglets?
Poor.
To fulfill the high energy demand of a newborn piglet to keep warm, they need to drink colostrum as soon as possible.
they need a heat source, such as a heating pad or a infra lamp
Why is it important for piglet to get colostrum?
They are born without antibodies, they will receive the immunoglobulins necessary for the immune system through the colostrum.
How long will the colostrum contain the valuable immunoglobulins?
100% at birth
50% after 6hours
0% after 48 hours
So it will be gone after 48hours
What is the pH of newborn piglets stomach? Compared to a adult pig?
pH of piglet = 5.2-5.3
Adult: 3.5
why is the pH so high in a piglets stomach?
It allows the immunoglobulin to go through and get absorbed in the small intestine
What does the colostrum contain high amount of?
- Proteins: Very high at the beginning, after week 2 it drops
- Vitamin A, Carotene
- Vitamin E, D, C and B
- Fe, Cu, Zn, Co, I
What does the colostrum have smaller amount of?
Fat and lactose
Iron supplement of piglet:
The colostrum of sows is not high in iron. the piglets are born with a small amount of iron supply.
Iron should be given as a supplment, can be given orally or as an injection
Why do we give iron PO?
Less risky. Less chance of iron toxicity
When do we administer the iron PO?
Day 7, 10 and 15
How much and when do we administer the iron injection?
150-200 mg Iron dextrane
At day 3-5
When will be introduce the solid feed to a piglet? How many meals each day?
At day 10, with creep feed.
4-6 meals per day
What will happen to the pH when we introduce solid feed?
The HCL secretion will be stimulated and it will decrease the pH.
Why do we introduce solid food to the piglets?
Solid feed will decrease lactic acid produciton and stimulates the HCL production
How much feed will be given to a piglet?
1kg of prestarter / piglet.
From day 10-weaning
How much of CP is given to a piglet?
min 20-21%
Which feed supplements is given to a newborn piglet?
Water
Through the sow, before parturition
- Amino Acids
- Glucose
- Vitamins
- Minerals:
