@darla,
In terms of feeds kasi i would advise na buy the feed that is more "sikat" in your area. Choose from the top three. They have that reputation in your area because they proven their worth....
Usually a pig will eat 4-5 sacks of feeds from birth onwards. In your case it is just around 2.5 bags? When you buy feeds ask your dealer for a feeding guide so you could have an idea.
