Pig feeds formulation is the process
of creating balanced diets that meet the nutritional needs of pigs for optimal
growth, reproduction, and health. Proper feed formulation is essential for
achieving maximum productivity in pig farming while minimizing feed costs,
which represent the largest expense in pig production.
Importance of Feed Formulation
The nutritional needs of pigs vary by
their stage of life, breed, weight, and purpose (e.g., breeding, meat
production). Properly formulated feeds ensure:
1.
Efficient Growth: Providing the right
mix of nutrients allows pigs to grow rapidly and efficiently.
2.
Optimal Health: Adequate nutrition
strengthens the immune system, reducing disease susceptibility.
3.
Reproductive Success: For breeding
pigs, balanced feed ensures successful mating, pregnancy, and healthy piglets.
4.
Cost Efficiency: Formulating feeds
carefully can help reduce production costs by avoiding overuse of expensive
ingredients.
Key Nutrients in Pig Feeds
Energy: Pigs require energy to
maintain their body functions and for growth. Energy sources include:
-
Cereal grains (corn, wheat, barley)
-
By-products like rice bran and
cassava
Protein and Amino Acids: Essential
for muscle development and growth. Common protein sources include:
-
Soybean meal
-
Fish meal
-
Groundnut cake
-
Synthetic amino acids (lysine,
methionine)
Vitamins and Minerals: Important for
metabolic functions and overall health. Key nutrients include:
-
Calcium and phosphorus (for bone
development)
-
Vitamins A, D, E, and K
-
Trace minerals like zinc, iron, and
selenium
Fats: Supplementing feeds with fats
improves energy density and palatability.
Fiber: Pigs, especially older ones,
need some fiber for proper digestion. Fiber sources include:
-
Alfalfa
-
Wheat bran
Factors Affecting Feed Formulation
Pig’s Age and Weight: Piglets,
growing pigs, and mature pigs have different nutritional needs. For instance,
piglets require higher protein content than finishing pigs.
Stage of Production: Pigs in
different production stages (gestation, lactation, growing, and finishing) have
varying dietary requirements.
Feed Ingredient Availability: The
cost and availability of ingredients affect the formulation. Locally available
materials can be used to reduce costs.
Digestibility: Some ingredients may
be less digestible for pigs, affecting how nutrients are absorbed.
Types of Pig Feed
Creep Feed: Given to piglets before
weaning, it is high in protein and easily digestible.
Weaner Feed: Fed to pigs post-weaning
to support rapid growth, typically containing around 20-22% protein.
Grower Feed: Fed to pigs from 25 to
70 kg, this diet contains lower protein than weaner feed but higher energy for
growth.
Finisher Feed: For pigs nearing
market weight, this feed emphasizes energy to maximize weight gain.
Breeding and Lactation Feeds: Special
formulations for breeding sows to maintain body condition during pregnancy and
nursing.
Steps in Feed Formulation
1.
Determine Nutritional Requirements:
Based on age, weight, and purpose.
2.
Select Ingredients: Choose from
available energy sources, proteins, and minerals.
3.
Balance the Diet: Ensure the feed
meets all nutritional requirements in the right proportions.
4.
Cost Optimization: Select ingredients
that offer the most cost-effective balance.
Feed Formulation Methods
-
Pearson Square Method: A simple tool
for formulating two-ingredient diets.
-
Software and Mathematical Models:
More advanced systems that optimize complex feed formulations for commercial
pig farming.
Pig feed formulation is a science that balances the nutritional needs of pigs with the cost and availability of ingredients. By providing the right feed, farmers can maximize pig growth, health, and profitability.

Pigs are a very
special breed of animal; they can be almost as much a pet as they are a
potential source of meat and income. The proper raising of pigs is disputed for
this reason, and there are multiple ways to go about it. To be an effective pig
farmer, you must not only understand the various different perspectives on
raising of pigs, but be able to adjust to the breeds you select and the method
by which you decide to raise each of them. From how they are fed to how you
treat and handle them as babies, pigs are a very unique species of farm animal.
This book provides every necessary detail you need to start raising pigs
immediately.
Topics cover a wide
variety of topics, including:
·
The difference between pigs that are raised for meat and those
that are used for disposal of compost or as pets
·
How the process of home butchering and processing is completed
What you can do to start fitting and showing your pigs in competition
·
The ins and outs of the pig raising business, including the breeds
you will encounter, the expectations of you by other pig farmers, and the
details you need to see to when you purchase your first pigs
·
How to start breeding your own pigs
Dozens of interviews
with top pig farmers and experts from around the country have been gathered for
this book to provide a detailed look at how the industry is run, including the
management of a pig herd, the health care of your pigs, and the daily
operations that must be completed in caring for your pigs.
If you are interested in the process of breeding and raising pigs, this book will provide every bit of information you need to get started.
