Application

Fodder yeast is used as protein addition with high content of vitamins of group B in the production of mixed feed for feeding agricultural and fur-bearing animals, birds and fishes. Fodder yeast is also used as protein addition to coarse and rich fodder (to powder hay, silage, beetroot, potatoes, to add into soups, porridges, food wastes etc.)

In contrast to vegetable feed protein microbic protein has the whole set of necessary aminoacids.

On its general nutritious value 1 kg of yeast contains 1.03 – 1.16 feed units. The metabolism energy of fodder yeast is 3600 kcal\kg.

The optimum carbohydrate-protein ratio in feed is when there 5-10% of yeast in dry mass of the whole feed. It’s shown by practice that average daily portion of yeast is 1 g per 1 kg of living mass of animals. The optimum ratio of carbohydrates and protein in feed reduces grain consumption in 1.5 2 times in cattle breeding. Every ton of yeast releases 5-7 tons of grain and provides extra 0.4 – 0.6 tons of pork, up to 1.5 tons of bird meat, about 25-30 thousand eggs, when being fed to dairy cattle yields of milk increase for 3-3.5 litres daily.

Production

Fodder yeast is obtained by microbiological synthesis of hydrolisates of vegetable raw materials on the basis of pentose and hecsose sugars. The main stages of fodder yeast production are: vegetable raw hydrolysis, microbiological synthesis of biomass from hydrolisate carbohydrates, thermal treatment, drying, granulating and packing.

Physical and chemical properties

Appearance

Powder from yellow till brown colour or granules ( diameter 12 mm, length up to 25 mm, with content of small fractions up to 2%.) The smell is characteristic of yeast.

Qualitative parameters

• Mass share of wet protein – not less than 46%
• Mass share of protein (according to Barnstein) – not less than 41%
• Mass share of ashes – not more than 10%
• Mass share of moisture – not more than 10%
• Metal-magnetic admixtures – not more than 20 mg
• Non-protein nitrous substances – are absent
• Living cells of producent – are absent
• Toxicity – is absent
• Total bacterial semen content – not more than 150

Transportation and storage

Powder yeast is packed in four-layered paper packets with valve. It’s transported by all kinds of covered transport means. It’s possible to transport 45-50 tons of yeast in a covered railway van. Granules are transported without packing in railway grain vans in bulk at 60 tons.

Fodder yeast is stored in closed premises protecting it from precipitation.

Warranty period of storing – 6 months since the day of manufacturing.
