NON-CONVENTIONAL FEEDS

Unconventional feeds

Feeds traditionally not used in livestock feeding—predominantly agricultural and forest by-products—often excluded due to traditional practices, poor palatability, or anti-nutritional factors.

Sunflower seed oil meal

Vegetable protein source containing $40\text{--}44\%$ high-grade protein rich in methionine; acts as an effective substitute for groundnut cake ($\text{GNC}$) in poultry starter and layer rations.

Anti-nutritional factors and limitations of guar meal

Contains residual non-digestible gum, trypsin inhibitors, causes poor palatability in cattle, and leads to diarrhea in young calves.

Niger cake

Oilseed by-product containing approximately $36\%$ crude protein and $14\text{--}18\%$ crude fiber; replaces groundnut cake on a protein-equivalent basis in chick feeds.

Karanja cake

Vegetable feed offering $30\%$ protein in young poultry diets, limited by polyphenolic compounds that exert deleterious effects on production and growth.

Rubber seed cake

By-product supplying $30\%$ crude protein and $9\text{--}10\%$ ether extract in pigs and cattle, whose primary safety limitation is cyanogenic compounds.

Dhaincha seed

Leguminous seed containing $30.33\%$ protein and $8.32\%$ lysine, restricted by trypsin inhibitors and tannins.

Safe feeding levels of Cassia tora seed in dairy cows

Safe up to $15\%$ of the concentrate ration when boiled, or up to $10\%$ when raw/unboiled, without depressing milk yield.

Corn gluten meal

Dried residue obtained from maize after removing most starch and bran; delivers $50\text{--}60\%$ crude protein.

Incubator and hatchery waste

Animal-origin by-product composed of cooked, dried, and powdered infertile eggs, unhatched eggs, and eggshell waste.

Frog meal

Animal protein derived from frog-leg processing waste; can substitute for fish meal at double the inclusion rate by weight in poultry rations.

Sal seed cake

Starchy byproduct left after oil extraction containing $50\%$ starch, $8\text{--}9\%$ protein, and $8\text{--}12\%$ tannins.

Tapioca thippi

Dried pulp residue remaining after tubers are crushed with equal water to extract starch milk and sieved to remove fiber.

Primary limiting factor in cassava waste (thippi and peel)

High sand and silica content (approximately $6\%$), restricting typical inclusion in Indian cattle feeds to $5\text{--}10\%$.

Triticale

Rye-wheat cereal hybrid containing $19.71\%$ protein and $67.78\%$ starch; utilized as an energy-protein grain in meat-type chick rations.

Kelp meal

Marine plant meal with negligible $NPK$, included primarily to supply essential trace minerals.

Rain tree pods

Sweet, palatable legume pods providing $16.7\%$ crude protein and roughly $64\%$ total digestible nutrients ($TDN$) for cattle concentrate mixes.

Sugar beet pulp

Low-sugar, high-fiber energy source with $10\%$ protein, $0.8\%$ calcium, and $0.5\%$ phosphorus, requiring vitamin A supplementation due to a complete absence of carotene.
