Recommendations on how to feed a Pigs:
- Fed for Growth by Free Access Feeding
- Feeding Using Diets
- Use of Lysine, Energy and Nutrients at specific stages of growth.
- Adequate Water Spaces
- Feed Spaces
Required Temperature for 140-180 days of age gilts.
68 degree F.
Lighting recommendation for gilts:
- 8-10 hours a day
Gilts should be maintained in groups within ____________ at least until they express first estrus.
Pens
The procedures that aid in induction of puberty in gilts involve:
- Some remixing stress with other new females.
- Some relocation or transportation event.
- Start of exposure to a mature boar.
How many percentage in the process of induction of puberty in gilts?
20-40% within a 10-20 day period.
How many percentage gilts assumed to cycle randomly within 5 days in a normal 20 day estrous cycle?
25%
The most critical for gilts, as crowding can be detrimental to puberty and growth rate.
Floor Space
Required time of exposure between160-180 day of age gilts each day.
30 minutes
What is the required time of a boar to access in a gilt pen?
15-30 minutes
Required feeds for 10 to 14 weeks of age (PIG)
Starter (18% CP)
Required feeds for 14-20 weeks of age (PIG)
Grower (16%CP)
Required feeds for 20 to 32 weeks of age (PIG)
Breeder
Replacement animals should be introduced & acclimatized to the normal microflora of the farm by:
- Introduction of the fecal material inside the pen taken from older stocks.
- Contact with older animals like boar or sow.
- Feeding with small amount of chopped placenta, aborted piglets or intestines of piglets which died from diarrhea.
- All of this practice would improve the resistance of the animal & coming litter against common diseases affecting farm animals.
When should we start feeding a starter ratio?
After Weaning
When to select replacements
After culling
Most common diseases affecting farm animals
mastitis or diarrhea
When is the gilt matured?
