), a byproduct of the dehulling step in cotton seed processing. In 2009, 9.2 million tons of cotton seed were used for feed ().Cotton seeds are mainly used locally and only small amounts are exchanged (0.74 million exported and 0.73 million ton imported in 2009). Research at the Universities of California and Pennsylvania has shown that feeding whole cottonseed to milking cows can stimulate higher milk fat test and help maintain milk persistency. For each 100 pounds of fiber produced by the cotton plant, it also produces about 162 pounds of cottonseed. During the solvent extraction process, the cottonseed kernels are subjected to fine grinding by pushing them through an expander and then the solvent is used to extract most of the oil. These are 20% protein, 20% oil and 3.5% starch. Cottonseed meal can be used in multiple ways: either alone or mixed with other plant and animal protein sources. Whereas there are reports on the improvement of cotton (Gossypium hirsutum L.) lint yield by poultry litter (PL) fertilization, there are no data about the impact of PL application on mineral composition of cottonseed. Washington, D.C. : U.S. Dept. What is the composition of fabric, specifically cotton, wool, fleece, and polyester? Extruded whole seed of cotton (Gossypium spp.). About one-third of the cottonseed produced from a typical crop is crushed for oil and meal used in food products and in livestock and poultry feed. The flaked cottonseed kernels are put under high pressure through a screw inside a constantly revolving barrel. Its fatty acid profile generally consists of 70% unsaturated fatty acids (18% monounsaturated, and 52% polyunsaturated), 26% saturated fatty acids. Chemical composition is one of the critical parameters to evaluate cottonseed’s quality and potential end use. Other name: full-fat cottonseed. The oil contains: Palmitic acid: 22-26%; Linoleic acid: 49-58%; Oleic acid: 15-20%; Arachidic / behenic and lignoceric acid: 10%; Cottonseed oil is described as a “naturally hydrogenated” substance by scientists. Table – 2. ", "Not Just For Cows Anymore: New GMO Cottonseed Is Safe For People To Eat : The Salt", "Cottonseed Meal 6-2-1 Organic Fertilizer", http://www.organic-gardening-for-life.com/cottonseed_meal.html, http://seeds-commerce.blogspot.ca/2004_12_01_archive.html, https://en.wikipedia.org/w/index.php?title=Cottonseed&oldid=967392054, Articles with unsourced statements from August 2015, Creative Commons Attribution-ShareAlike License, This page was last edited on 13 July 2020, at 00:39. Cotton actually is two crops, fiber and seed. It can be cost effective and provides nutrients with a high protein value of about 23%, crude fibre value of 25%, and high energy value of 20%. In October 2018, the United States Department of Agriculture approved for farming a genetically modified version of cottonseed developed by Dr. Keerti Rathore of Texas A&M AgriLife Research that contains ultra-low amounts of gossypol in its seeds. The seeds are further hulled and polished to release the soft and high-protein meat. The seeds are about 15% of the value of the crop and are pressed to make oil and used as ruminant animal feed. , The refined seed oil extracted from the kernels can be used as a cooking oil or in salad dressings. For unit weight of fibre, about 1.6 units of seeds are produced.  The toxin remains present in other parts of the plant to protect against pests, but is not yet approved by the Food and Drug Administration for human consumption. The boll is a protective fruit and when the plant is grown commercially, it is stripped from the seed by ginning and the lint is then processed into cotton fibre.  Cottonseed meal fertilizers can be used for roses, camellias, or vegetable gardens.. The seeds are about 15% of the value o… cotton (Gossypium hirsutum L.) lint yield by poultry litter (PL) fertilization, there are no data about the impact of PL application on mineral composition of cottonseed. of Agriculture, 1921 Fibers grow from the seed coat to form a boll of cotton lint. Cotton fibers would be … Extruded whole seed of cotton (Gossypium spp.). , The outer coverings of the cottonseed, known as cottonseed hulls, are removed from the cotton kernels before the oil is extracted. The screw pushes out the oil through the openings made in the barrel. Table 1. 2 Using Cotton Byproducts in Beef Cattle Diets Nutrient Composition The nutrient composition of cotton byproducts is listed in Table 1. Cottonseed production (both for oil and feed use) was 42 million tons in 2010. Additional Physical Format: Online version: Creswell, Charles F. (Charles Franklin), 1886-Composition of cotton seed. Goals / Objectives The overall goal of this research project is to develop novel cottonseed fatty acid composition in seed oils of cotton plants as value-added resources for the cotton industry. An inert matter percentage is not required for cotton, peanut, or tobacco seed in North Carolina.  Cottonseed is considered a safer alternative to corn supplemented diets due to its low starch content. Cottonseed hulls. It is pale yellow in color and is widely used for cooking. , Cottonseeds are toxic to humans and most animals due to the presence of gossypol, though it is tolerated by cows, and cannot be consumed by humans without processing.
