Peanut shell as feed supplement

Peanut shell as feed supplement and source of oil

By: Danilo Bulabos


Peanuts are abundant in the Philippines both in tropical and subtropical areas. Young pods of peanut known as legumes develop  underground which, after roasting, is used as food. Peanuts shells can be utilized as feed supplement for livestock, poultry and oil.

The peanut shell is tested by using hot water analysis for protein sampling, biuret test for carbohydrates content, and iodine test for glucose.

In the experiment, 30% peanut shell was recovered from a kilo of peanut. From 300 grams of refined peanut shell, 250 grams of feed was obtained, while 5% crude fiber was generated.

Analyses of feed sample confirmed the presence of 12.55% moisture, 2.66% ash, 1.10% crude fat, 29.63% protein and unquantified  amount of carbohydrates

Legumes contain 20 to 40% protein which is three times more than cereal grains. They are

also good source of raw materials for various food substitutes. Roots of legumes contain

nitrogen-fixing bacteria which serves as fertilizer in the soil planted with these plants.

or more a year if his cultivation is good and the soil is fertile. Because there is always a big

less, equals one-half kilo of milk or three eggs of moderate size. And even if it brings high

calories, it has cholesterol.

Peanut Production Technology – part 3



·         Using a peg-toothed harrow, cultivate or off bar 10-15 days after emergence to control weeds.

·         If needed, hill up at 25-30 days after emergence to ensure easier penetration of pegs into soil and proper formation of pods particularly in clay soil. However, hilling up may promote build up of Sclerotium roltisii which causes stem rot disease and sprouting of early developed pods.

·         Avoid cultivating at the peak flowering and pegging stages to prevent abortion of first open flowers and disturbance of pod formation.
