Supply and demand of brewery waste analysis in Lithuania

A wide range of agro-industrial byproducts are available in large quantities which have considerable nutritional potential. Brewery waste (Brewer’s grains) is a typical example of such unrealized potential. Brewery waste is a byproduct of ethanol industry which uses cereal grains as feed stock. When grain is fermented to produce ethanol, primarily the starch is utilized, leaving behind a protein rich residue that can be used in livestock diets. The goal of the study: assess the demand and supply of brewery waste in Lithuania. The objects of the study: 1. Analyze the data in the scientific literature on the brewery by-products chemical composition, nutritive value and usability. 2. To find out the saladin as a protein additive in livestock farming use in Lithuania. 3. Analyze and evaluate the possible factors having a or not having the impact on the choice of saladin using in feeding of farm animals. 4. Assess the factors that may affect the further use of saladin. Results of the study: 1. In the scientific literature we found, that there is a lot of crude protein in malt seed – in young vegetable tissue. But up to 50 percent these nutrients may include non-protein fraction of nitrogen compounds. The main nutrients - fiber. In the brewery waste compounds carbohydrates, starch and water-soluble minerals, mainly calcium and phosphorus. But this product lacks the water-soluble minerals and vitamins. Compared with raw materials, in the brewery waste there are 3-4 times more cell wall constituents of matter and twice as much protein, so the brewery waste seen as a high-fiber diet with high protein content. Saladin commonly used in animal feeding. The differences in the chemical composition of brewery waste may be attributed to the nature of grains (barley, maize and rice) used for beer making as raw material, their inclusion level and the type of channels they pass through. Apart from the above mentioned reasons, variations in the nutritive value of the grains used, strain variation, period of fermentation, processing techniques and analytical procedures followed might have contributed for their variations in the chemical composition of brewery waste between different investigators. 2. Analysis of the use of saladin in Lithuanian farm animals, it was found that 70 percent of Lithuanian farm uses saladin, as an additive in animal feed, and only one-third of households (30 percent) do not use saladin. Under the assumption of its use in Lithuania, it was found that 30 percent of all respondents said that saladin uses in the farms that hold from 26 to 100 animals. 20 percent of respondents use saladin in a very small farm - a potential small-scale farmers. 3. 30 percent of the respondents are not used saladin. 85.70 percent interviewed said that the advertising is relevant and only 14.30 percent of respondents the advertisement was not important. 71.30 percent of respondents emphasized that relatives, friends, neighbors, opinion was important, 28 60 percent – not important. The incentives has an important role in the choice of saladin - because 85.70 percent of respondents pointed out that this is an important criterion, while 14.30 percent it is noted as very important. 4. 66.70 percent of respondents nevertheless bought saladin, if only to more information about this product utilization, and 33.30 percent - buy it if would lower the price. The biggest reason why consumers do not buy saladin is that it cannot find the information and advertising and is close to home for selling space. The best source of information appeared - interviews with family members, colleagues, friends and neighbors (70 percent)
