POTENT YEAST-PROTEIN FEED PRODUCTS Yeast feed, e.g. yeast cultures, called YC for short, is a medium that has been converted, by culturing yeast on it, into a high quality bio-active protein product. The product is powder in form and light yellow to brown in color, and disseminates a special smell like yeast. The product is salmonella-free, and has proved to be highly effective in fish and shrimp feeding when incorporated into the diets. Nutrient composition: The contents is a protein feed, the contents of the three main limiting amino acids ( Methionine ,Lysine and Tryptophane)are all higher than those in soybean meal, with lysine being 25% higher. The product is also rich in vitamins (especially B vitamins)and various trace minerals and growth promoting factors ,and is a green bio-active protein feed product that is both nutritious and health improving in its function. Moisture≤10%，Ash≤10%,Yeast cells≥4billion/g,Living cells≥70%,Crude protein divide three rate: 1.CP≥40% 2.CP≥50% 3.CP≥60%. Charicteristics: ▲ High protein bioavai lability :The apparent protein digestibility of the YC is 89.3% in growing pigs and 91.1% in laying hens; ▲ Animal performance improving: YC is highly effective and economic in improving animals′growth, daily gain, feed efficiency and reproductive performance; ▲ Production cost reducing: YC can replace partly or even totally the fish meal in the diets of animal, poultry, fish and shrimp, and diet cost can be reduced by 40-100RMB yuan per ton; ▲ High safety: YC is free of salmonell; nontoxic to human, animal, fish and shrimp; environment-friendly; doesn′t cause any cross-contamination; ▲ Stable quality: YC can stay stable in mash feeds, pellets and premixes; has good flowing ability; is non-electrostatic absorbent; is tolerant to gastric acid and heal(in pelleting) and can keep higher proportion of living cells. Target animals and he usage: It can be used in diets for various animals, poultry, fish and shrimp, and the usage(kg)is as follows: Cattle:50-60g Pigs 40-50g Chickens、Ducks、Geese 30-60g Rabbits、Pigeons、Game birds 30-40g Fishes、Shrimps 120-180g Crabs:120-150g Eels:150-200g Package and storage: 25kg/bag Store in dry, dark and cool places with good ventilation.
