Insects as feed are insect species used as animal feed, either for livestock, including aquaculture, or as pet food. As livestock feed production uses ~33% of the world's agricultural cropland use, insects might be able to supplement livestock feed. They can transform low-value organic wastes, are nutritious and have low environmental impacts. [20]
Blood meal is a dry, inert powder made from blood, used as a high-nitrogen organic fertilizer and a high protein animal feed. N = 13.25%, P = 1.0%, K = 0.6%. It is one of the highest non-synthetic sources of nitrogen. It usually comes from cattle or hogs as a slaughterhouse by-product.
Agricultural chemistry is the chemistry, especially organic chemistry and biochemistry, as they relate to agriculture. Agricultural chemistry embraces the structures and chemical reactions relevant in the production, protection, and use of crops and livestock .
Raising livestock and poultry, for meat, dairy and eggs, is another traditional farming activity that complements growing. Organic farms attempt to provide animals with natural living conditions and feed. Organic certification verifies that livestock are raised according to the USDA organic regulations throughout their lives. [83]
Bone meal provides phosphorus and calcium to plants, along with a largely inconsequential amount of nitrogen. [4] The N-P-K rating of bone meal is typically 3–15–0 [5] along with a calcium content of around 12% (18% CaO equiv.), [6] although it can vary quite a bit depending on the source from 1–13–0 to 3–22–0.
Livestock and poultry producers will need to comply with more specific standards if they want to label their products organic under final rules announced Wednesday by the U.S. Department of ...
In order for manure to be considered organic it must come from organic livestock or certified organic growers. [12] If organic manure is not available, they are permitted to use non-organic manure as long as the animals have room to roam, are not kept in the dark, and growers abstain from using genetically modified feeds. [12]
Neutral detergent fiber (NDF) is the most common measure of fiber used for animal feed analysis, but it does not represent a unique class of chemical compounds.NDF measures most of the structural components in plant cells (i.e. lignin, hemicellulose and cellulose), but not pectin.
