Production of beer based on maize and sorghum gives rise to a byproduct (brewer's grains) which appears less fibrous and more nutritious than the conventional barley-based by-product. Studies were conducted to determine its proximate composition and effect as broiler finisher diet when fortified with 8% palm oil, 3% bone meal and 0.25% of lysine, methionine, salt and trace mineral/vitamin premix, respectively. The maize/sorghum based dried brewer's grains so treated was compared with a conventional commercial broiler finisher diet in a 4-week feeding trial involving 6-week old broiler chicks of Anak breed. The maize/sorghum based dried brewers' grains contained 28.64%, 6.5%, 7.27%, 12.42% and 45.17% crude protein, fat, total ash, fibre and NFE, respectively. Fortified maize/sorghum based brewers’ grains supported weight gain for finisher broilers comparable to the control, the commercial finisher diet.

Introduction. An important reserve for increasing the profitability and competitiveness of livestock production would be solving the problem of feed protein deficiency in animal feeding. Significant contribution to the solution of this problem can be made by using high-protein waste of oil extraction (meal, cake), alcohol (bard), brewing (brewers grains) industries for feeding purposes.
 Since the liquid brewers grains is poorly preserved and easily spoiled, especially during the summer, and its transportation over long distances requires large costs, in this regard, there is a current problem of drying the liquid brewers grains and its usage as a high-protein fodder for feeding animals in dry form as part of animal mixed fodder.
 The purpose of our research is to study the effectiveness of feeding dry brewers grains to repair heifers of the Jersey breed.
 Research materials and methods. Research on the feeding dry brewers grains effectiveness was carried out on repair heifers of the Jersey breed at the age from 2 to 12 months on the basis of the farm SE “Dan-milk” in Cherniakhiv district of Zhytomyr region. Dry brewers grains produced by private joint-stock company (PJSC) “Obolon” were used for the research.
 Research result. The content of crude protein in 1 kg of dry brewers grains, which was used in scientific and economic research, was 24.46%, or 244.6 g per 1 kg of dry brewers grains.
 In order to study the effectiveness of feeding dry brewers grains, three groups of repair heifers of the Jersey breed were formed for the research, 8 heads each, according to the following scheme: one control group of repair heifers, and the other two were research groups.
 According to the research scheme, the control group of repair heifers received a standard grain mixture without dry brewers grains. The difference in the feeding of repair heifers of research groups consisted in different levels of feeding dry brewers grains, which was included in the grain mix of the II research group in the amount of 15%, and the III research group - in the amount of 20%.
 As a result of the research, there was an increase in the average daily gains of the II research group heifers, which ration included 15% of dry brewers grains in the mixture composition: for the period from 2 until 6 months – up to 0.811 kg against 0.786 kg, for a period from 6 until 12 months – up to 0.671 kg against 0.657 kg, for a period from 2 until 12 months – up to 0.727 kg against 0.709 kg in the control group.
 At the age from 9 and 12 months of cultivation of repair heifers of the II research group, which grain mixture included 15% of dry brewers grains, there was a tendency of the main body measurements increase: height at the withers, chest girth and oblique torso length, compared with the repair heifers of the control group. In heifers of the III research group, which ration included 20% of dry brewers grains of the grain mixture, the main body measurements were lower than in heifers of the control and II research groups.
 While studding main hematological indicators of the repair heifers of the control and research groups at the age of 6 and 12 months of cultivation, it was found that the inclusion of 15% of dry brewers grains in the grain mixture of the ration of the repair heifers of the II research group improved their passage of biosynthetic processes and the use of nitrogen, which indicates a tendency to increase in their blood total protein content compared to the control group primarily due to globulins, which indicates an improvement of immune-protective properties in the heifers of this group. The increase in the content of total protein and globulins against the control group in the heifers of the III research group, grain mixture for which included 20% of dry brewers grains, was manifested to a lesser degree.
 Summary. The inclusion of dry brewers grains in the grain mixture of the rations of repair heifers of the Jersey breed of the II research group in the amount of 15% of the total weight of the grain mixture, provided an increase in their average daily gains compared to the repair heifers of the control group and amounted to for the period from 2 until 6 months – 3.2%, for the period from 6 until 12 months – 2.1%, for the period from 2 until 12 months –2.6% with a tendency to increase the main measurements at the age of 9 months: height at the withers up to 104.0 cm against 103.5 cm, chest girth – 142.8 cm against 141.4 cm, oblique torso length – 131.8 cm against 131.4 cm in the control group.

The results of experimental studies of physical and chemical indicators and amino acid composition of raw brewer’s grains from Belorechensky (the Krasnodar Territory) and Maykop (the Republic of Adygea) br eweries have been presented. The purpose of the research is to compare the physicochemical parameters and amino acid composition of raw brewer’s grains obtained pneumatically at the Belorechensk brewery and hydraulically at the Maykop brewery. Analyzes carried out in an accredited laboratory and testing center have shown that fresh grains from both breweries are non-toxic. Both breweries use PILSNER MALT by «Kurskiy Malt» and produce beer using classic technology. The content of sugar and starch in absolutely dry matter is higher in brewer’s grains of the Maykop brewery, which indicates a deeper additional sugar starch used in the technology of the Belorechensk brewery. The presence of essential amino acids methionine, arginine, valine, threonine, etc. characterizes the nutritional value of the grain. The content of crude protein in the brewer grains of the Belorechensk brewery is higher compared to that in the Maykop brewery grains, 5,1% and 4,2%, respectively, and the content of nitrogen-free extractive substances is higher in the brewer grains of the Maykop brewery and makes up 9,3% and 8,8% in spent grains of the Belorechensk brewery. The data obtained are consistent with the data of other researchers. Due to the high moisture content in the Maykop brewer’s grains, its indicators have been determined after moisture draining through a sieve. Analysis of the technological stages of beer production has shown that a pasteurization unit was installed at the Belorechensk brewery before bottling beer, which helps to increase its shelf life and destroy the active action of microorganisms, but to reduce the saturation of the beer taste.

Brewery and distillery co-products such as Brewers Grains and Draff have long been recognised as effective forage replacers within cattle rations. Recently the value of these feeds as concentrate replacers has been demonstrated (Hyslop and Roberts 1990, Forbes and Johnson 1990) with 4kg of concentrates being typically replaced by 16kg of Brewers Grains or Draff within dairy cow rations.Moist wheat distillers grains (Supergrains) contain higher levels of dry matter, energy and protein compared to Brewers Grains or Draff. At the single distillery producing the co-product, the main raw material used is wheat with a small quantity of malting barley to assist in the enzyme conversion of starch. The cereals and yeast used in the process pass through the entire fermentation and distillation process with the material left after the spirit has been distilled off being concentrated by centrifugation to form Supergrains with a dry matter (g/kg), metabolisable energy (MJ/kg DM) and crude protent content (g/kg DM) of 260, 14.0 and 320 respectively..The objective of this work was to evaluate the effect of replacing concentrates with Supergrains with bulls fed ad libitum grass silage.

The eating quality of beef from steers fed either conventional, brewers' grain or wheat-based distillers' grain rations during backgrounding and finishing was assessed. Carcass traits, raw proximate composition and fatty acid composition of the longissimus muscle were generally unaffected (P < 0.05) by dietary treatment. Furthermore, diet had no effect on sensory properties (tenderness, juiciness, flavor) and shear values of loin roasts. Thus, beef producers can take advantage of these alternative protein sources to provide lean, nutritious beef for consumers.

<p>Two assays were carried out to determine i) the nutritional value of dried brewers’ grains and ii) the effects of inclusion of this ingredient in growing rabbit diets on animal performance and economic performance of the breeding unit. In the digestibility assay, a total of 28 male rabbits were distributed in 2 groups differing in the diet offered to animals: a reference diet (35.51% neutral detergent fibre and 16.50% crude protein [CP]) and a test diet (60% of reference diet and 40% of dried brewers grains). The dried brewers’ grain contained 37.9% of CP and 3371 kcal digestible energy/kg dry matter. In the performance study, 80 weaned rabbits (40 males and 40 females) were allotted at 40 d of age to 5 groups differing in the inclusion levels of dried brewers’ grains (0, 7, 14, 21 and 28%) from 40 d to 90 d of age. Inclusion of dried brewers’ grains did not affect the live weight at 90 d, the feed intake between 40 d and 90 d or the dressing percentage of rabbits (on average 223 g, 96 g/d and 51.3%, respectively). There was no effect of diet on the meat quality parameters (69.5% water holding capacity, 25.6% cooking loss, 3.4 kg/cm<sup>2</sup> Warner-Bratzler shear force and pH 5.70) and inclusion levels above 14% reduced the feed cost (–18%; P</p>

Protein solubility in mineral buffer, and protein degradability with bacterial protease, of condensed distillers solubles, distillers dried grains, brewers dried grains, raw, roasted and extruded soybeans, corn silage, haycrop silage, hay, corn gluten feed, multiage solulac and lactosy-urea (Ewoplus) were in­vestigated for use in ruminant feeding. The proteins of distillers dried grains, brewers dried grains, roasted and extruded soybeans and corn gluten meal were highly Insoluble in mineral buffer with average solubilities of 4.50%, 10.47%, 8.07%, 13.12% and 5.40% respectively. Lactosyl­urea (Ewoplus) was 100% soluble. The protease of streptomyces griseus was used to determine protein degradability. The degradable proteins of distillers grains, brewers grains, raw and roasted soybeans, and corn gluten meal were resis­tant to protease action. Extruded soybeans, distillers solubles, forage feedstuffs and Ewoplus were readily degradable.

AbstractBrewers’ spent grains (BSG) are the main waste product of the brewing industry, accounting for about 85% of the total waste materials. Their composition is different (due to various brewing technologies) but includes high levels of dietary fiber, proteins, essential amino acids, polyphenols, antioxidants, vitamins and fats. The aim of the present study was to investigate the phenolic content and antioxidant activity (the radical scavenging assay (DPPH) and ferric reducing antioxidant power (FRAP)) of 19 different malt types and their BSG. The highest phenolic content was demonstrated by the BSG of Caraaroma malt, whereas the BSG of Carafa Special type 1 had the highest DPPH radical scavenging activity and ferric reducing antioxidant power. Based on the results obtained, malts with the highest biological value were selected for inclusion in the composition of functional foods.
