  • This study was conducted to investigate the effects of Total Mixed Ration (TMR) with wet brewer's grain on feed intake, nutrient digestibility and nitrogen retention of castrated Korean black goat. For feeding trial, forty castrated Korean black goats were divided into four treatment groups, which were fed TMR containing 20, 30, 40% of wet brewer's grain. For digestibility trial, twelve castrated Korean black goats were allotted to treatments in four groups of three goats. Results are summarized as follows. Dry matter (DM) contents of TMR with wet brewer's grain was $63.35{\sim}66.02%$, that of crude protein was $14.49{\sim}15.36%$, Acid detergent fiber (ADF) and Neutral detergent fiber (NDF) were $28.24{\sim}29.08,\;53.27{\sim}54.85%$, each. These were not different by supplemental level of brewer's grain in TMR. However, Non-fibrous carbohydrate (NFC) contents were lower according to increase wet brewer's grain in TMR. Average daily gain of control group were higher than those from TMR with wet brewer's gain (p<0.05). Intake of DM, Organic matter (OM) and NFC of TMR supplemented with 20% of brewer's grain were higher than those of other treatments (p<0.05). Crude protein (CP) and digestible CP intake of TMR diets supplemented wet brewer's grain was intended to higher than those of a control group. Digestibilities of DM, OM and NDF in control group were higher than those from TMR with wet brewer's grain (p<0.05). Digestibilities of CP of TMR with supplemented wet brewer's grain was tend to be higher than those of a control group. Nitrogen retention of TMR supplemented wet brewer's grain was tend to be somewhat higher compared to the control group

  • Lignin degrading bacterium Pseudomonas sp. LG2 was able to degrade lignin substrate to a lot of APPL compound. APPL compound was detected in culture supernatants from Pseudomonas sp. LG2 grown with BSC(brewer's spent grain). FAE(ferulic acid esterase) and xylanase are induced from Pseudomonas sp. LG2 in the presence of carbon sources such as oat spelt xylan, HBSG I, II(hydrolyzed brewer's spent grain I, II) and AFBSG(autoclaved fraction from brewer's spent grain). However, xylanase and FAE are not induced by growth of Pseudomonas sp. LG2 on xylose and arabinose. Pseudomonas sp. LG2 is grown on medium containing oat spelt xylan, HBSG I, II and AFBSG and the induction of FAE and xylanase activities of extracellular proteins determined during 14 days. Maximum level of xylanase activity(5.3 U/mg) found at 6 days in culture contained oat spelt xylan as carbon source, whereas maximum level of FAE activity(15.4 mU/mg) was found at 8 days in culture contained AFBSG as carbon source. Most ferulic acid was released in culture supernatants when Pseudomonas sp. LG2 grown on oat spelt xylan, HBSG I, II and AFBSG. FAE of extracellular enzymes was also specific activity on methyl ferulic acid, methyl caffeic acid and methyl p-coumaric acid respectively, but not methyl sinapinic acid, methyl vanillic acid and methyl gallic acid.

  • Twenty yearling lambs of Southeast Nigeria dwarf, liveweight ($18{\pm}1.9 kg$) were grouped into 5 treatments. Dry brewer's grain was substituted for maize offal in the experiment diets namely A to E at 0%, 15%, 30%, 45% and 60% respectively, as supplement to low quality, dry season cassava leaf top and Andropogan gayanus hay at 1:1 ratio that lasted for 56 days. After which 5 of the lambs (average bodyweight=$24.3{\pm}1.5kg$) were transferred to metabolism crates to determine the digestibility and nitrogen/protein balance studies. While the mean group intakes were (945.9, 996.1, 1,040.5, 1,148.5 and 1,037.7 g conc. DM/day), the growth rates were (115.1, 124.1, 152.5, 168.5 and 123.1 g liveweight gain/day), respectively. There was a recorded decline in both intake (p>0.05) and growth rate (p<0.05) as the level of dry brewer's grain was increased beyond 45% of the supplement. Similar trend was observed on the protein and organic matter efficiency ratios (p>0.05) together with the organic matter intake. The urine nitrogen output was also significant (p>0.05). The work further revealed that, at a certain critical level of intake, dry brewer's grain is able to support growth rates measurable to or better than those noted when feeding maize offal to lambs, and went on to prove dry brewer's grain as an attractive supplementary feed for the drier months of the year, in the Southeast of Nigeria.

  • This study was conducted to investigate the effects of dietary Hewer's dried grain supplementation on growth performance and digestibility in growing pigs. A total of forty-eight pigs (19.3 kg, average initial body weight) were used during 42 days. Dietary treatments included: 1) CON (basal diet), 2) BDG5 (basal diet + 5 % brewer's dried grain) and 3) BDC10 (basal diet + 10 % brewer's dried grain). Each treatment had 8 replicates of 2 pigs per pen in a randomized complete block design. Growth performance was not affected by treatments. However, in nutrient digestibility, DM digestibility was higher in BDG5 treatment than CON and BDG10 treatments. Nitrogen digestibility was the highest in BDG10 treatment and among another treatments, also, BDG5 treatment was higher than CON treatment. And, energy digestibility was higher in BDG10 treatment than CON treatment. In conclusion, dietary brewer's dried grain supplementation is not reduced on growth performance and improved on nutrient digestibility.

  • Brewer's spent grain (BSG) is a waste product of the beer industry, and γ-aminobutyric acid (GABA) is a physiologically active substance important for brain and neuron physiology. In this study, we used the bacterial strains Bacillus velezensis DMB06 and B. licheniformis 0DA23-1, respectively, to ferment BSG and produce GABA. The GABA biosynthesis pathways were identified through genomic analysis of the genomes of both strains. We then inoculated the strains into BSG to determine changes in pH, acidity, reducing sugar content, amino-type nitrogen content, and GABA production, which was approximately doubled in BSG inoculated with Bacillus compared to that in uninoculated BSG; however, no significant difference was observed in GABA production between the two bacterial strains. These results provide the experimental basis for expanding the use of BSG by demonstrating the potential gain in increasing GABA production from a waste resource.

  • This study was conducted to investigate the feeding effects of total mixed fermentations (TMF) with spent mushroom (Flammuliua velutipes) and wet brewer's grain on estimating the productivity and nutrient utilization of Korean black goats. Four experimental groups were set up with each of the 5 animals for a 30-day feeding trial on growth performance. 12 black goats with regard to nutrient digestibility were allocated to 4 groups of 3 animals each by a latin-square design control group (offered concentrate and rice straw) and 3 treatment groups (TMF with 15% spent mushroom and 25% wet brewer's grain (T1), 10, 30% (T2) and 5, 35% (T3)). The average daily gain (ADG) of the control and T1 treatment groups was higher than that of the T3 treatment group (p<0.05). Dry matter (DM) and organic matter (OM) intake (kg/head) for T1 and T2 treatment groups were significantly higher than those of the control group (p<0.05). The digestibility of DM and OM for the control group (62.39~63.39%) and the T1 treatment group (65.02~65.25%) were significantly higher than those of the T3 treatment group (56.39, 59.01%) (p<0.05). Further, nitrogen retention was significantly higher in the T1 treatment group (p<0.05). Thus, these results conveyed that productivity and nutrient utilization were similar between TMF with spent mushroom and wet brewer's grain and commercial feeds. However, this study also suggested that feed must contain 25~30% spent mushroom due to the fact that the productivity of Korean black goats was decreased by increasing the content of spent mushroom.

  • Mealworms, Tenebrio molitor (Coleoptera: Tenebrionidae), are widely used as food sourcefor animal rearing as well as human diet. Conventionally, mealworms raised on wheat bran. In this study, we investigated the effects of brewer's spent grain (BSG) on the growth of mealworm larvae to reduce the rearing cost. We prepared five different diets with various BSG content, 0, 10, 30, 50, and 70% of heated air dried BSG with wheat bran. We compared survivorship, larval weight, developmental duration, pupation rate, and pupal weight of five different groups of T. molitor raised on these five diets. The larval survivorships were almost similar with the control group except a group with 70% of BSG. For the larval weight, groups with 30% and 50% of BSG gained more weight than that with control treatment, 0% of BSG. For the developmental period, the groups with 30% of BSG took less time compared to the control group. In all treatment groups, more than 90% of pupation rate were observed. Especially, the group with 30% of BSG showed highest pupation rate among the five groups. Wheat bran with 30~50% of BSG was the optimal diet for successive insect rearing among the five diet treatments. Based on this study, we concluded that adding BSG to wheat bran helps to improve the quality of T. molitor and to reduce the rearing period.

  • The effects of replacing pork back fat with brewer's spent grain (BSG) pre-emulsion for physicochemical, textural properties, and sensory evaluations of reduced-fat chicken sausages are evaluated. Control was prepared with 15% pork back fat, and three reduced-fat chicken sausages were formulated with the replacement of 20, 25, and 30% pork back fat with BSG pre-emulsion. The pH level of reduced-fat sausages formulated with BSG pre-emulsion is lower than that of the control (p<0.05). The redness, yellowness, and apparent viscosity of reduced-fat chicken sausages increase proportionally with increasing BSG pre-emulsion (p<0.05). With increasing BSG pre-emulsion concentration, the fat contents and energy values are decreased in reduced-fat chicken sausages (p<0.05). The BSG pre-emulsion improves the hardness, gumminess, and chewiness of reduced-fat chicken sausages (p<0.05), and the reduction in fat and the addition of BSG pre-emulsion had no influence on the cohesiveness of the chicken sausage. And there is no significant difference in the overall acceptability among control, T1 (chicken sausage with 20% of BSG pre-emulsion, 10% of fat addition), and T2 (chicken sausage with 25% of BSG pre-emulsion, 5% of fat addition) (p>0.05). Therefore, our results indicate that BSG is effective dietary fiber source for manufacturing of reduced-fat meat product and suggest that 20-25% of BSG pre-emulsion is suitable for pork back fat in chicken sausages.

  • The giant mealworm beetle, Zophobas atratus (Coleoptera: Tenebrionidae), is a tropical beetle. As this beetle can be used as an ingredient in animal feed, the effects of brewer's spent grain (BSG) on the development and nutritional value of Z. atratus were investigated. As results, there were no significant differences on the larval survival rate, body weight, and duration at different content of BSG, mixed with conventional feed, wheat bran (WB). Based on these results, BSG can be mixed with wheat bran as a Z. atratus food ingredient without any problems. The nutritional value was compared between 100% wheat bran control and 50% BSG experimental groups. The moisture, crude protein, carbohydrates, and amino acids were 1.1-1.4 times higher in the 50% BSG group. In the BSG group, the linoleic acid content was 1.6 times higher than that in the control group. In the wheat bran group, the oleic acid content was 38.4%, which was 1.3 times higher than that in the BSG group. As minerals, the control and BSG groups showed high potassium and phosphorus contents. In terms of hazardous materials, four heavy metals (lead, mercury, arsenic, and cadmium) and two microorganisms (Escherichia coli and Salmonella spp.) were not detected. There were no significant differences in developmental characteristics between the wheat bran and BSG mixed groups, and the nutritional values were better in the BSG mixed group. Therefore, BSG can be used as alternative food source for rearing Z. atratus.
