The present invention relates to gelled feed products, means for making said products and a method for manufacturing gelled feed products. The product comprises 80-98 weight % raw material of animal or marine origin pre-treated with KOH and/or NaOH, KHCO , K CO , NaHCO , Na CO , or (NH ) CO and 0.5-5 weight % alginate or pectin, a calcium source standard feed ingredients and calcium. The product may contain 0-10 weight % fish meal or carbohydrates. Said means are raw material of animal or marine origin pre-treated with alkali giving said raw material a pH of 8-12. The method comprises mixing raw materials of marine or animal origin, comprising offals, alginate or pectin, and a calcium source and standard feed ingredients, particulating said mixture into any useful geometrical shape, expose it to acid treatment in a bath. The raw material is pre-treated with alkali or to addition of alginate or pectin. The resulting mixture is formed into desired shape and treated in an acid bath to form the gelled product. Preferably the acid bath is having a pH of 0.5-5.5 and the retention time in the bath is 30 seconds-12 hours. The preferred acid is formic aid.

Gelled feed products, means for making the products and method for manufacture of said products

The present invention relates to aqueous preservatives, containing ammonium tetraformate or any other combination of formic acid and ammonia, for grass and other agricultural crops, fish and fish products and meat products, having reduced corrosiveness and irritation to skin, comprising 0.5-5 weight % glycerol. Preferably the content of glycerol in the preservative is 0.75-1.5 weight %. The preservative may further contain at least one metal corrosion inhibitor and/or antioxidant.

Animal feed additives and feedstuff containing said additives

The invention provides a new feed product, especially a fish feed product in the form of pellets or particles, with high fat content and superior physical properties. The product is made by immersing feed pellets in a first hot oil bath with a temperature higher than 100.degree. C. to secure drying of and simultaneous fat absorbtion. This treatment is followed by a cooling in a warm oil bath kept at a temperature of 40.degree.-60.degree. C. This completes the fat absorbtion and results in a dry product consisting of hard and smooth particles with high fat content, which are free flowing and do not agglomerate.
