How Can You Manage Pig Diet

Being a pig owner, you must evaluate the proper ratio and amount to feed your pig by following recommended guidelines and paying attention to your pig’s condition and health status. A grown pig generally can sustain herself quite nicely on two cups of pig food per day.

Don’t allow your pig to trick you into feeding her more than her recommended ratio. You can make your pig think she is getting more than the usual amount of food by applying some of the following suggestions.

This is ideal to feed small portions of meals to your pig in a day. Indeed, this will depend upon your working schedule; but, if possible, split her daily food allotment into three equal portions and spread the feeding over the course of the day.

A good routine would be to feed one-half of the pellets in the morning, a fresh vegetable salad for lunch, and the other half of the pig chow at supper time. If two meals suit your schedule better, then feed half of the pellets before work and the other half at your usual dining time. A before-bed snack seems to make piggies the most content.

How Automated Feed Dispenser is Helpful on Controlling Overfeeding

It is a nice idea to use automated feed dispensers to partition the pig’s meal into small portions. In this way, you can offer them specified feed portions after specified intervals. This is very helpful in controlling overfeeding and subsequently, managing weight.

This allows you to feed pigs exactly what they need, eliminate waste, and control your cost.

How Treat Rewards Can Stop Overfeeding in Pigs

Moreover, If your pig whines around constantly hoping for food treats, don’t succumb. The credo is: ‘No Free Food’ What does this mean? It means that your pig is required to complete a task or in some way cooperate with you before a food reward is earned.

This is especially indicated at the toddler stage (3 to 5 months of age) when a pig forms the behaviors that will remain with her for her entire life. Use food to train your pig to do either trick, such as “circle” and “sit” – or obey commands, such as “come” and “stay.”

Your pig will be highly motivated and eager to please know there is a reward attached to the behavior.

It is absolutely acceptable for you to feed your pig her complete portion at the designated meal times, but for treats and extras, abide by the no-free food rule. For families who have the tendency to feed their pets too many extras, set aside the complete day’s ration of treats in a bowl, away from the pig.

As the day progresses, family members may use this food to train their pigs. When the tidbits are gone — that’s it. Be prudent.

don’t let your pig train you

After all, you are not a human vending machine, much to your pig’s dismay. You are, however, the one who makes the rules, you know – not the pig-a-rooter.
