A

It will slow down the growing process

24
Q

What change is made to the diet of a sow about ten - fourteen days before she is bred? What is the process called?

Study These Flashcards
A

Flushing: increasing the feed intake 10 - 14 days before being bred. This is done to make sure her nutrient levels are at peak and will make her better suited for pregnancy

25
After farrowing, how should a sow be fed?
Feed to appetite - whatever mama wants want to make sure the sow does not lose any body condition while lactating
26
T/F: Sows should have their feed increased 2-4 weeks prior to farrowing?
True
27
At want point after farrowing, is the sows food intake decreased?
When the piglets begin weaning (3-4 weeks old)
28
How is the weaned pig fed?
Typically ad lib - in the beginning it will typically have more milk products for palatabilty and protein since they just got off a strictly milk diet
29
What is phase feeding?
Adjusting the diet to the needs of the pigs as he grows
30

3-4 weeks of age
38
When does the active immunity of a piglet begin and peak?
starts at about 2 weeks and continues to increase
39
What are factors that can limit the potential of the early weaned pig?
Genetics Health Optimum nutrition through phase feeding
40
Grower rations are adjusted to what factors?
Sex, age, and genetic potential
41
What must you avoid in the gilt?
Over feeding It makes it more difficult for them to get pregnant or give birth when they are obese - when they do give birth they have a tendency to not eat and lose body condition making them less productive
42
What complications can be seen when gilts have too little weight gain?
Inability to sustain lactation | Delayed return to estrus and rebreeding
43
What are essential feed ingredients for lactating females?
Lysine - to have good protein function Water Fiber - helps prevent constipation
44
Why don't you want a boar to get too fat?
That will decrease his breeding condition/potential
45
Anemia is a primary problem in what pigs?
piglets Especially those that are born indoors and do not have access to soil
46
How do you treat or prevent anemia in piglets?
Supplement iron It is best absorbed via injection *given in the neck to avoid staining market meet

Vitamin deficiency due to a poorly balanced diet
49
T/F: The substance that is present in the least amount relative to the demand, will limit the metabolic process
TRUE
50
What minerals can cause issues if they are not balanced in the diet?
Calcium and phosphorus | Should be Ca: 1-1.3 to P 1
51
What problem can occur if there is too much calcium in the diet?
It can tie up the zinc in the diet leading to a zine deficiency
52
What skin condition occurs with a zinc deficiency?
parakeratosis bilateral abnormal keratinization of the skin - forming horny scales that start as brown spots
53

55
How long does it take a pig to reach market weight?
only 5 - 6 months
56
What is added to the diet to help digest phosphorus more efficiently? What other benefits are seen?
Phytase This has been shown to increase growth by 5% or more and also decreased the odor and quantity of manure
57
What is the benefit of conjugated linoleic acid?
Can potentially decreased the unwanted back fat on pigs and also increase their immune system
