  • This study was conducted to compare and evaluate fermentable and nutritional characteristics of brewery meal-based fermented feedstuffs supplemented with Aspergillus oryzae (AO) and Saccharomyces cerevisiae (SC). Experiments were divided into three treatment groups; fermented feedstuff supplemented with $1\%$ of AO(FFAO), fermented feedstuff supplemented with $1\%$ of SC(FFSC), and fermented feedstuff supplemented with $0.5\%$ of AO and $0.5\%$ of SC(FFAS). For changes of crude protein contents by 48 h fermentation, there were no significant differences among treatments. Ether extract(EE) contents were significantly increased by 48 h fermentation (p<0.05). Neutral detergent fiber(NDF) contents of FFAO, FFSC and FFAS were significantly decreased by 48 h fermentation(p<0.05), but acid detergent fiber(ADF) and acid detergent lignin (ADL) contents were not different. The pH of FFAO and FFAS was decreased more rapidly than that of FFSC(p<0.05), reaching a plateau after 24 h. Alcohol content was increased rapidly until 18 h in FFAO and was increased rapidly until 12 h in FFSC and FFAS, and alcohol content of FFAO, FFSC and FFAS was maintained constantly after 24 h. The ammonia N content of FFAO, FFSC and FFAS was 0.022, 0.073 and $0.040\%$ at 48 h, respectively, and then ammonia N was over twice higher in FFSC than in FFAO and FFAS(p<0.05). Dextrose content was increased until 6 h in FFAO but was rapidly decreased in FFSC and FFAS until 6 h(p<0.05). Lactate content was higher in FFAO and FFAS than in FFSC(p<0.05). Consequently, when we added AO in formulation of fermented feedstuff with brewery meal which moisture content was high, EE, alcohol, and lactate contents were increased, but NDF and ammonia N contents were reduced. Therefore, it is expected that AO will be effective to increase the feed value and the preservation of fermented feedstuff with a high moisture content.

  • This study was conducted to examine the effects of supplementing coated vitamin C+E with cottonseed on rumen fermentation and body weight gain, blood metabolites and hormone concentrations in Hanwoo steers fed fermented feedstuff. Experiments were done with two treatment groups, T1 without any supplements and T2 supplemented with coated vitamin C+E and cottonseed. Ruminal pH was lower in T2 than in T1 at 3h after morning feeding (p<0.05), but was higher in T2 than in T1 at 6 and 9h after morning feeding (p<0.05). Ruminal ammonia concentration was higher in T2 than in T1 for 12h after morning feeding (p<0.05). Concentrations of acetate, propionate, butyrate and total-VFA were higher in T2 than in T1 at 3h after morning feeding (p<0.05), but were lower in T2 than in T1 at 9 and 12h after morning feeding (p<0.05). Average daily gain and concentrations of blood metabolites and hormones between T1 and T2 were similar. Results indicate that supplementation of coated vitamin C+E and cottonseed to fermented feedstuff affects on ruminal pH, ammonia and VFA. But it has no influences on body weight gain and concentrations of blood metabolites and hormones in Hanwoo steers.

  • The results on the chemical characteristics of the pork fed with fermented feeds are summarized as follows; 1) The pork treated with fermented feeds had lower fat and higher protein content than control pork in proximate compositions. It is considered to be the improvement of the quality. 2) It was not recognized to the difference of oxidation level among the sample porks. 3) Oleic acid was the highest concentration in the components of fatty acid of pork. The rate of the saturated and unsaturated fatty acids is 38.8 % : 59.9 % in the ordinary meat, 40.8 % : 57.8 % in the a high-grade meat, and 36.3 % : 62.0 % in the pork treated with fermented feeds. In addition, the essential fatty acid content of them is 14 %, 11.2 %, and 16.7%, respectively. 4) Glutamic acid was the highest composition in total amino acids and the essential amino acid content was 39% in both an ordinary meat and the pork treated with fermented feeds, and 14 % in high-grade meat. 5) It was no difference in the inorganic content among the samples. The water holding capacity by extraction meat juice was higher to 92 % in the pork treated with fermented feeds and 15.6 % in a loss in quantity by heating than others. Thus, the pork bred with fermented feeds was evaluated to be good in terms of processing and cooking.

  • This study was carried out to investigate the feeding effects of dietary supplementation of fermented spent mushroom substrates (F-SMS) from Pleurotus eryngii with Bacillus subtilis CS21 and Saccharomyces cerevisiae on Hanwoo steers. The cellulase and xylanase producing bacteria, designated CS21, was isolated from freshly spent mushroom substrates from Pleurotus eryngii and used as probiotics to fermented spent mushroom substrates. Twenty Hanwoo steers were allocated into two feeding groups and assigned equally to two dietary treatments; Control (TMR) and TMR including 30% F-SMS (30% F-SMS TMR). Total gain and feed intake was significantly greater in the 30% F-SMS TMR than control (p<0.05), but carcass grades were not influenced by the experimental diets. Based on this study, fermented spent mushroom substrates from Pleurotus eryngii with B. subtilis CS21 and Saccharomyces cerevisiae is able to use as an ingredient feed in TMR for Hanwoo steers.

  • To determine nutritive value and suitability of deep-stacked broiler litter for deer, the influence of supplementary levels of broiler litter on digestibility, dry matter intake, and nitrogen balance was investigated in male spotted deer (Cervus nippon) fed a commercial mixed(complete) ration. The deep-stacked and ground broiler litter was supplemented at the level of 0%(Control), 15%(T1) and 30%(T2) on the basis of fresh matter to the mixed ration. All treatments had similar palatability at about 3% body weight of dry matter intake. Dry matter digestibility was highest in Control and lowest in T2(P<0.05). Digestibility of crude protein was lowest(P<0.05) in T2. Dry matter and digestible dry matter intake was similar in all treatments. Daily body weight gain was not affected by treatments. Feeding 15 or 30% of broiler litter to male deer resulted in similar nitrogen intake, fecal nitrogen excretion and daily nitrogen retention(g/d), compared with feeding Control. These results suggest that up to 30% of broiler litter may be fed to male deer without deleterious effects on deer performance.

  • Out of 96 yeast strains isolated from various natural habitats, five strains were screened based on their ability to ferment agricultural biproducts such as rice-, barley-and wheat-bran, and sawdust. These were identified as Hansenula anomala var anomala, Candide utilis, C. pelliculosa, Debaryomyces hansenii, and Irpex lacteus. Using these yeasts the above mentioned agricultural biproducts were fermented in various combinations. The fermented product was fed to 180 male Starcroses for eight weeks and obtained a body weight increase of 15.1g a day, while the unfermented control feed increased 10.5g a day.

  • This study was conducted to determine effects of and a proper level of barley malt sprouts(BMS) addition as well as to develop an effective fermentation method when broiler litter(BL) was ensiled or deepstacked with 0 to 10% levels of BMS. Mixtures were ensiled or deepstacked for one month and physico-chemical analyses were made between before and after treatments. Addition of BMS up to 10% enhanced nutritional quality of either of ensiled or deepstacked BL mixtures. Especially, the quantity and quality of protein were improved with the addition of BMS to BL. However, the still high pH values after ensiling of various mixtures indicated that anaerobic fermentation did not effectively occur with the addition of up to 10% of BMS to BL and consideration of fermentation aids appeared to be necessary. For deepstacking, addition of BMS to BL increased internal peak temperature(from 56 to $70^{\circ}C$) of the stack, indicating that the added BMS to BL stimulated the degradative activity of fermentative microorganisms. The deepstacking method was more effective than the ensiling method for the manufacture of hygienical fred mixture with BL and BMS.
