Cotton Seeds – Oilseed By-Product for Oil Extraction, Animal Feed, and Industrial Applications

Introduction

Cotton seeds are the seeds obtained from cotton plants (Gossypium spp.), primarily as a by-product of cotton fiber production. While cotton fiber is the main commercial product, cotton seeds are highly valuable for oil extraction, animal feed production, and various industrial uses.

Cotton seeds play a major role in the global oilseed industry. After the cotton lint is removed, the seeds are processed to extract cottonseed oil and to produce cottonseed cake or meal, which is widely used in livestock feed.

These seeds are produced in large quantities in cotton-growing regions and contribute significantly to agricultural value chains.

Product Definition

Cotton seeds are the oil-rich seeds separated from cotton bolls after fiber removal. They are mainly used for:

• Cottonseed oil extraction
• Animal feed (cottonseed cake/meal)
• Industrial processing

They are considered a valuable by-product of cotton fiber production.

Product Features

1. High Oil Content
