Objective: This study was conducted to investigate the effect of fermented cottonseed meal (FCSM) on growth performance, carcass traits, and fat deposition in white-feather broiler chickens. Methods: A total of 480 male one-day-old white-feather broiler chickens were selected randomly and divided into four groups with six replicates of 20 chickens in each. The experimental chickens were fed diets including 3%, 6%, or 9% FCSM fermented by Candida tropicalis until 42 days old. In the experiment, the chickens of the control group were fed soybean meal. Results: FCSM supplementation linearly decreased the feed conversion ratio from d 15 to 21 and d 36 to 42, respectively (p<0.05). The percentage of carcass and semi-eviscerate increased in response to dietary FCSM supplementation at d 21 (p<0.05). The percentage of eviscerated and semi-eviscerate of 3FCSM was higher than that in other groups at d 35 (p<0.05). At the age of 42 d, the percentage of carcass increased in a quadratic way among increasing FCSM in diets (p<0.05). The subcutaneous fat thickness linearly decreased with the increasing levels of FCSM at d 21 (p<0.05). Gompertz and Logistic functions provided a better fit on abdominal fat and subcutaneous fat, respectively. The best fitted equation predicted that the maximum growth rate of abdominal fat weight and subcutaneous fat thickness occurred at d 28. FCSM had no significant effects on the shape of growth curve of abdominal fat weight and subcutaneous fat thickness, but reduced the height of the curve. Birds receiving the 6FCSM diet for 21 d had smaller adipocyte surface and lower serum glucose as well as triglyceride concentration. Conclusion: FCSM is beneficial for broiler chickens as it positively affects their growth and carcass in addition to altering their fat deposition.

본 연구는 농 식품부산물 중 비지박, 사자발약쑥 그리고 커피박의 유효미생물 (L. acidophilus ATCC 496, L. fermentum ATCC 1493, L. plantarum KCTC 1048, L. casei IFO 3533) 발효 사료원이 젖소 급여용 TMR (대조구) 중 대두박을 주로 대체한 각 비지박 (SC), 발효 비지박 (FSC), 발효 비지박+발효 사자발약쑥 부산물 (1:1, DM basis, FSCS) 3, 5, 10% 그리고 발효 비지박 + 발효 커피박 (1:1, DM basis, FSCC) 3, 5, 10%의 반추위 내 미생물 발효특성을 알아보기 위해 9처리구를 이용하여 3반복으로 in vitro 시험이 실시되었다. 배양 6~8시간대에 FSCS와 FSCC 처리구는 SC와 FSC 처리구에 비해 높은 pH 수준을 유지하였고, 대조구에 비해 낮은 pH 수준을 유지하였다 (p<0.05). 또한 배양 24시간대 FSC와 FSCC 3% 처리구는 가장 높은 pH를 유지하였다 (p<0.05). Gas 생성량은 배양 4~10시간대까지 FSCS와 FSCC 처리구가 대조구 보다 유의적으로 높았으나 SC와 FSC 처리구 보다 낮은 결과를 나타내었다 (p<0.05). 건물소화율은 배양 12시간대까지 FSC 처리구에서 유의적으로 높았고 (p<0.05), 24시간대에는 FSCS 10% 처리구가 가장 높은 결과를 나타내었다 (p<0.05). $NH_3-N$ 함량은 배양 4시간대까지 대조구에서 가장 낮았고 (p<0.05), 24시간에서는 FSC 처리구가 가장 높은 결과를 나타내었다 (p<0.05). 미생물단백질 합성량은 배양 시작 시 FSC, FSCS 그리고 FSCC 처리구가 4종의 Lactobacillus spp.에 의한 발효 때문에 대조구와 SC 처리구에 비해 높았으며 (p<0.05), 배양 10시간대 FSC 처리구 보다 SC, FSCS 그리고 FSCC 처리구에서 유의하게 높은 결과를 나타내었다 (p<0.05). Total VFA 농도는 배양 6~12 시간대에는 FSC 처리구에 유의하게 높았고(p<0.05), 배양 24시간대에는 FSCS 처리구에서 가장 높았다 (p<0.05). Acetate 농도는 배양 0~12 시간대에 FSC 처리구에서 가장 높았으며 (p<0.05), 24시간대에는 FSCS 5, 10% 처리구에서 가장 높은 결과를 나타내었다 (p<0.05). Propionate 농도는 FSC 처리구가 배양 0~10시간대까지 가장 높았으며 (p<0.05), 전체 배양기간 동안 FSCS 5, 10% 처리구와 FSCC 처리구에 비해 높은 경향을 나타내었다. Acetate/Propionate 비율은 배양 12시간대에 SC 처리구에서 가장 높았으며, 배양 24시간대에는 FSCS 3% 처리구가 가장 낮은 결과를 나타내었다 (p<0.05). $CH_4$ 가스 생성량은 FSC 처리구에서 배양 0~10시간대까지 가장 높았으며 (p<0.05), 24시간대에는 가장 낮은 결과를 나타내었다 (p<0.05). 배양 4~10시간대까지 FSCS와 FSCC 처리구는 SC와 FSC 처리구에 비해 유의하게 낮은 $CH_4$ 가스 생성량을 나타내었고 (p<0.05), 사자발약쑥과 커피박 함량이 증가할수록 $CH_4$ 가스 생성량은 배양 종료 시까지 낮은 경향을 나타내었다. 따라서, 본 in vitro 시험에서 젖소 급여용 TMR에 SC, FSC, FSCS 그리고 FSCC의 대체효과는 FSC 처리구에서 배양 초기부터 12시간대까지 반추위 내 미생물 발효 특성이 가장 높았다. FSCS와 FSCC 처리구는 배양 6~8시간대 부터 반추위 내 미생물 작용이 높아지는 특징을 나타내었으나, 배양 시작 후 6~8시간대까지 gas 생성량 및 $CH_4$ 가스 발생량은 낮아지는 특징을 나타내었다. 이와 같은 결론은 FSC는 젖소용 TMR 사료원 대체 효과가 높으며, TMR 사료원 중 FSCS와 FSCC 대체효과는 배양 초기 다소 낮은 반추위 내 미생물 발효 특성을 나타내었으나 $CH_4$ 저감효과를 나타내었다. 또한 배양 후기에는 SC와 FSC의 반추위 내 미생물 발효 특성과 비슷한 경향을 나타내어 TMR 사료원으로써 이용 가치가 높을 것으로 사료된다.

This study was conducted to investigate the effects of fermented king oyster mushroom by-products diet (FMBD) on the growth performance, blood characteristics, and carcass traits of fattening pigs and its economics. The fermented diet mainly contained 40.0% king oyster mushroom (Pleurotus eryngii) by-products, 20.0% corn, 28.0% soybean meal, 0.1% supplemental probiotics and 0.08% cellulase. The mixed ingredients were fermented for 1 d at $37^{\circ}C$ followed by 9 d at room temperature, after which they were dried at $45^{\circ}C$ for 3 d. Pigs (n=96) were divided into eight heads per pen, four diet treatments and three replications. The basal diet (C) was substituted with 20% (T1), 50% (T2) and 80% (T3) FMBD. The concentration of crude protein (CP) was significantly higher (p<0.05) at the end of the fermentation period. The average daily gain (ADG) and feed efficiency were significantly lower (p<0.05) in T3 than C. Additionally, carcass grade was significantly better (p<0.05) in all treatments than C and the ratio of high carcass grade was higher. Although substitution of FMBD decreased growth performance, it improved carcass grade and decreased the feed cost of fattening pigs. Therefore, it was expected that the increase in the utilization ratio of FMBD will reduce the cost of animal production.

Objective: The effects of adding fermented feed to a pelleted total mixed ration (PTMR) on the growth performance of lambs remain unclear. The present study aimed to investigate the feed efficiency and productivity of lambs that were fed PTMR containing fermented soybean meal (FSM) or wheat bran (FWB). Methods: Sixty 90-d-old hybrid lambs were randomly allocated into 12 pens (5 lambs/pen) that were randomly assigned to 4 dietary treatments (3 pens/treatment) with PTMR (basal diet), 2% FSM, or Lactobacillus- or yeast-FWB (L-FWB or Y-FWB) addition in the basal diet. Results: The findings showed that lambs fed 2% FSM supplemented diet had enhanced (p<0.05) average daily gain (ADG) and carcass yield (p = 0.015), while they had a decreased (p = 0.006) feed conversion ratio compared to that of other three groups. Inclusion of FSM or FWB in PTMR improved (p<0.05) the nutrient digestibility, while it reduced the urea nitrogen content in serum compared to the PTMR group. Additionally, the decreased ratio of N excretion to ADG (p<0.01) was observed with FSM and L-FWB supplementation compared with the PTMR and Y-FWB groups. Conclusion: In conclusion, feeding the fermented feed-supplemented diet improved nutrient digestibility and growth performance, and 2% FSM-supplemented diet exhibited superior production-promoting efficiency to lambs.

Objective: This study investigated the effect of fermented biogas residue (FBR) of wheat on the performance, serum biochemical parameters, and meat quality in pigs. Methods: We selected 128 pigs (the mean initial body weight was $40.24{\pm}3.08kg$) and randomly allocated them to 4 groups (1 control group and 3 treatment groups) with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received a corn-soybean meal-based diet, the treatment group fed diets containing 5%, 10%, and 15% FBR, respectively (abbreviated as FBR5, FBR10, and FBR15, respectively). Every group received equivalent-energy and nitrogen diets. The test lasted 60 days and was divided into early and late stages. Blood and carcass samples were obtained on 60 d. Meat quality was collected from two pigs per pen. Results: During the late stage, the average daily feed intake and average daily gain of the treatment groups was greater than that of the control group (p<0.05). During the entire experiment, the average daily gain of the treatment groups was higher than that of the control group (p<0.05). Fermented biomass residue did not significantly affect serum biochemical parameters or meat quality, but did affect amino acid profiles in pork. The contents of Asp, Arg, Tyr, Phe, Leu, Thr, Ser, Lys, Pro, Ala, essential amino acids, non-essential amino acids, and total amino acids in pork of FBR5 and FBR10 were greater than those of the control group (p<0.05). Conclusion: These combined results suggest that feeding FBR could increase the average daily gain and average daily feed intake in pigs and the content of several flavor-promoting amino acids.

This study was conducted to evaluate the effect of fermented food waste (FFW) supplementation on growth, nutrient digestibility and pork quality of growing pigs. A total of 48 crossbred pigs were assigned to four treatments in a randomized complete block (RCB) design. Treatments were 1) Control (basal), 2) FFW 2% (basal+2%FFW), 3) FFW 4% (basal+4%FFW) and 4) FFW 6% (basal+6%FFW). Diets were formulated based on corn-soybean meal and the FFW products were provided to weaning, growing and finishing periods. During the whole experimental period, FFW treatment groups showed similar ADG, ADFI and G:F ratios (P>.10) compared to control group. However, In the finishing period, pigs fed 6% FFW tended to be lower ADG than other dietary treatments (P=0.13) resulting in lower final weight. All pigs showed inconsistent blood urea nitrogen (BUN) concentrations pattern. In metabolic trial, nutrient digestibility was not affected by the supplementation of FFW. The pork quality was affected by the supplementation of FFW based upon pork pH, lipid peroxidation (TBARS) and meat color analysis. These results suggested that utilization of fermented food waste to growing pig's diet reduce production cost without any detrimental effect on pork quality when it was provided at low level.

A total of 629 Duroc${\times}$Landrace${\times}$Large White crossbred pigs were utilized in three experiments (Exp. 1, 222 pigs weighing $25.6{\pm}2.0\;kg$ BW; Exp. 2, 216 pigs weighing 5$6.2{\pm}4.3\;kg$ BW; Exp. 3, 191 pigs weighing $86.4{\pm}4.6\;kg$ BW) conducted to determine the effects of fermented potato pulp on performance, nutrient digestibility, carcass traits and plasma parameters in growingfinishing pigs. Each experiment lasted 28 d. The pigs were assigned to one of two corn-soybean meal-based diets containing 0 or 5% fermented potato pulp. The inclusion of fermented potato pulp increased weight gain (p<0.05) in experiments 1 and 2 and increased feed intake (p<0.05) in experiment 2. Feed conversion was improved (p<0.05) in experiment 2 and showed a tendency to improve (p<0.10) in experiments 1 and 3 when pigs were fed fermented potato pulp. Fermented potato pulp increased (p<0.05) dry matter digestibility in experiments 1 and 3 and energy digestibility in experiment 2. Feeding fermented potato pulp decreased plasma urea nitrogen (p<0.05) and alanine aminotransferase (p<0.05) in experiments 1 and 2, while plasma aspartate aminotransferase was decreased (p<0.05) in experiment 3. Dietary fermented potato pulp did not affect the carcass characteristics of finishing pigs. Feeding fermented potato pulp reduced (p<0.05) fecal ammonia concentration in all three experiments. In conclusion, feeding growing-finishing pigs diets containing 5% fermented potato pulp improved weight gain and feed conversion without any detrimental effects on carcass traits. The improvements in pig performance appeared to be mediated by improvements in nutrient digestibility.
