  • Finding alternative feeds, such as sesame hulls and Prosopis juliflora species can attenuate difficulties of feed shortage and reduce the cost of animal feed in arid and semi-arid countries. Thirty-two Black male kids with similar initial weights (BW = $16.7{\pm}0.80\;kg$) and $120{\pm}5\;d$ of age, were used to evaluate the effect of replacing barley grains and soybean meal with Prosopis juliflora pods (PJP) and sesame hulls (SH) on growth performance, digestibility and carcass and meat characteristics. Kids were equally divided into four dietary treatment groups for an 84-d fattening period. Treatment diets had similar crude protein (CP) and metabolizable energy (ME). The treatment groups were: (T1) no PJP nor SH, (T2) 10% PJP and 20% SH, (T3) 15% PJP and 15% SH, and (T4) 20% PJP and 10% SH. A tendency was detected (p<0.08) for dry matter (DM), crude protein (CP), organic matter (OM) and neutral detergent fiber (NDF) intakes that were greater for T2 than T3 and T4 while T1 was not different from all other treatment groups. Ether extract (EE) intake was the greatest (p<0.05) for T2 and the lowest for T1. Acid detergent fiber (ADF) intake was greater (p<0.05) for T2 than T1 while T3 and T4 were intermediate. Final live weight, average daily gain (ADG) and feed conversion ratio (FCR) were comparable among different treatment groups. Digestibility of DM, OM, CP, NDF and ADF were similar among all treatment groups, however, EE digestibility was the lowest (p<0.05) for T1 when compared to other treatments. In addition, nitrogen intake, nitrogen in urine and retained and retention percentages were similar among all treatment groups. However, N loss in feces was higher (p<0.05) for T2 than T3 and T4 while T1 was intermediate. No differences were observed among treatment groups with respect to fasting live weight, hot and cold carcass weights, dressing-out percentages, mesenteric fat, visceral organs, carcass cuts percentages and carcass linear dimensions. No differences were also observed for dissected loin, leg, rack and shoulder tissues except in the total bone % for loin cuts and in the meat to bone ratio for rack cuts. T3 has the greatest total bone % and the lowest meat to bone ratio when compared to all other treatment groups. No differences were observed between treatment groups in all quality characteristics of the longissimus muscle. The present study demonstrates the potential of using PJP and SH for growing kids without adverse effects on growth performance, carcass characteristics and meat quality.

  • 본 연구는 농산부산물인 왕겨, 보리외피, 대두외피에 적당한 열처리 및 활성화 처리를 하여 다양한 크기의 다공성 표면을 가진 회화재 및 활성탄 형태의 흡착제를 제조하여 식용유지의 불순물인 유리지방산과 색소 성분인 lutein에 대한 흡착 효과를 살펴보았다. 회화재 형태의 흡착제인 왕겨 회화재(RHA), 보리외피 회화재(BHA), 대두외피 회화재(SHA)는 처리 농도가 증가할수록 유리지방산 흡착 효과도 증가하여 대두 유의 산가가 감소하였는데 SHA와 BHA의 유리지방산 흡착효과가 컸고 RHA와 실리카의 효과는 작았다. SHA와 BHA는 5% 처리시 탈검 대두유의 산가를 82~86% 감소시킨데 비해 RHA는 29%, 실리카는 19% 감소시켰다. 회화재 형태의 흡착제 처리와 달리 활성탄 형태의 흡착제인 왕겨 활성탄(RHC), 보리외피 활성탄(BHC), 대두외피 활성탄(SHC)은 처리 농도를 증가시켜도 유리지방산 흡착 효과가 증가하지 않았다. RHC는 5% 처리시 탈검 대두유의 산가를 16%, BHC와 SHC는 8~10% 감소시켰으나, 상업용 활성탄은 거의 영향을 주지 않았다. 흡착제 종류별 lutein 제거 효과에서는 회화재 형태의 흡착제의 경우 7~8%의 미미한 감소를 보인 반면, 활성탄 형태의 흡착제의 경우 5% 처리 농도에서 RHC는 56%로 가장 큰 흡착 효과를 보였고, BHC는 41%, SHC는 52%, 상업용 활성탄은 49%의 lutein 함량 감소를 나타냈다. 따라서 lutein에 대한 흡착 효과는 회화재 형태의 흡착제보다 활성탄 형태의 흡착제가 훨씬 뛰어남을 알 수 있었다. 회화재 형태의 흡착제들은 비표면적과 전체 세공 부피는 작으나 세공의 크기가 큰 중간 세공이나 거대 세공으로 주로 이루어져 있고, 이런 특성이 유지 중에 불순물로 함유되어 있는 유리지방산 흡착과 관련이 있는 것으로 보인다. 반면에 색소 성분인 lutein은 회화재 형태의 흡착제 처리에서는 거의 감소 효과가 없고 활성탄 형태의 흡착제에서 감소 효과를 보인 것으로 보아 미세 세공에 흡착되는 특성이 있는 것으로 보인다. 따라서 흡착제를 이용하여 식용유지를 정제할 때는 회화재 형태와 활성탄 형태의 흡착제들을 혼합하여 사용하면 유리지방산과 lutein을 동시에 제거할 수 있을 것이다.

  • Objective: The objective was to determine standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in cereal grains and various co-products fed to growing pigs. Methods: Ten feed ingredients tested were barley (9.3% CP), lupin kernels (31.1% CP), and wheat (11.3% CP) as cereal grains, and 2 sources of corn gluten feed produced in China (21.6% CP) and Korea (24.6% CP), corn gluten meal (65.3% CP), lupin hulls (11.6% CP), rice bran (14.5% CP), soybean meal (44.8% CP), and wheat bran (15.4% CP) as co-products. Ten experimental diets were formulated to contain each ingredient as a sole source of N and an N-free diet was used to correct basal endogenous losses of CP and AA. All diets also contained 0.5% Cr2O3 as an indigestible index. A replicated 11×6 incomplete Latin square design with 11 dietary treatments, 6 periods, and 22 animals was employed. Twenty-two barrows with an initial body weight of 64.6±4.9 kg were equipped with a T-cannula in the distal ileum. An experimental period consisted of a 4-d adaptation period and a 2-d collection period. Results: The SID of CP in the barley, lupin kernels, wheat, 2 sources of corn gluten feed, corn gluten meal, lupin hulls, rice bran, soybean meal, and wheat bran were 84.7%, 90.5%, 90.4%, 77.4%, 74.6%, 89.5%, 90.4%, 74.4%, 86.9%, and 63.4% (standard error of the mean [SEM] = 5.3, p = 0.006), respectively. The respective SID values of Lys were 75.5%, 88.4%, 83.9%, 74.7%, 62.4%, 80.3%, 83.9%, 78.5%, 88.0%, and 71.2% (SEM = 3.3, p<0.001), and the SID values of Met were 83.6%, 88.7%, 89.4%, 85.7%, 78.3%, 88.9%, 89.4%, 85.3%, 91.1%, and 77.0% (SEM = 2.4, p<0.001), respectively. Conclusion: The ileal digestibility of protein and amino acids varies among the feed ingredients fed to pigs.

  • 대두 가공 부산 폐기물로부터 발생되는 대두피에서 식이섬유를 분리하여 대두 자엽 및 타 식물 유래 식이섬유와 설사개선에 미치는 효능을 비교 평가하였다 설사를 유발시킨 Sprague Dawley 수컷 흰쥐를 불용성 식이섬유인 셀룰로오스(CON), 불용성과 수용성 식이섬유가 혼합된 대두 자엽 유래 식이섬유(S-COTL), 불용성 대두피 추출 식이섬유(S-HULL) 및 수용성인 치커리 식이섬유(CHI)가 각각 동량 함유된 식이의 네 군으로 나누어 24시간 동안 실험 식이를 공급한 결과 CON과 S-HULL에서 S-COTL과 CHI보다 약 10-20% 가량 높은 변수분 감소 효과를 나타내었다. 그리고 탈수 증상의 척도인 혈청 삼투압 변화 측정 결과 역시 네 군 중 CON과 S-HULL에서 가장 높은 감소율을 보였다. 이 결과를 통해 대두피에서 추출한 식이섬유의 설사 개선 효과가 기존의 타 식이섬유에 비해 우월하다는 사실을 생화학적으로 해석할 수 있었다. 나아가 현재 경관급식 환자식에 대두 자엽 유래 식이섬유 및 기타 수용성 식이섬유 등이 사용되고 있음에도 자주 발생하는 잠재적이고도 심각한 위협이 되는 설사증상을 본 연구 결과에서 제시한 대두피 추출 식이섬유원으로 대체하는 것에 의해 해결할 수 있을 것으로 기대해 볼 수 있다.

  • 본 연구는 산업체에서 발생되는 총 19종 부산물들의 동물사료로의 활용성을 증대시킬 목적으로 유기성 부산물들의 배출 현장을 방문하여 부산물 발생 및 이용 현황을 조사하고, 각각의 화학적 특성을 평가하고, 분석된 화학적 성분들 중에서 부산물 사료의 동물 소화율을 예측할 수 있는 신뢰성 있는 지표를 발굴하고, 사료 배합비 설계 시 실제 분석치 대신 문헌 성분표상의 수치 이용의 위험성을 진단하기 위해서 실시되었다. 실험 결과, 부산물들의 발생 현황 및 이용 현황은 매우 다양하였다. 부산물들을 영양적 주성분에 따라 분류하였을 때, 과일가공부산물(사과박, 감껍질, 배박, 포도박)과 제과부산물은 에너지 사료에 속하였고, 비지, 동물성 사료(혈액, 우모분, 닭내장), 유가공슬러지는 단백질 사료에 속하였으며, 대두피, 버섯잔사, 맥아피, 폐지, 육계분은 조사료에 속하였다. 반추위내용물과 식당 원 남은 음식물의 영양적 특성은 각각 소 TMR사료와 양돈용 배합사료 성분에 근접하였다. 대두박과 비교해서 아미노산 함량은 혈액과 우모분은 상대적으로높았고 (P<0.05), 맥아근, 유가공 슬러지, 식당원 남은 음식물들은 상대적으로 낮았다 (P< 0.05). 단백질 원 부산물사료들의 펩신 소화율은 66~99%의 범위에 속하였다. 부산물 종류에 상관없이 in vitro 건물 소화율은 식당 원 남은 음식물, 제과부산물, 사과박, 대두피, 배박, 감껍질, 맥아피, 맥아근, 비지, 포도박, 반추위 내용물, 가금부산물, 육계분, 폐지, 버섯잔사, 유가공 슬러지, 우모분, 혈액의 순으로 높았다 (P <0.05). In vitro 건물 소화율은 화학성분들 중에서 비섬유성 탄수화물과 가장 높은 상관관계(r=0.68)를 보였으며, 이는 비섬유성 탄수화물이 부산물 사료들의 소화율 예측 시 신뢰성 있는 지표로 이용될 수 있음을 의미한다. 부산물 사료들의 실제 화학 분석치와 문헌에 제시된 성분표 상의 수치간의 차이는 큰 편이었다. 따라서 동물 사료 내에 다량의 부산물 사료를 이용할수록 동물 생산성의 극대화를 위해서는 실제 분석치의 이용이 필수적인 것으로 사료되었다.

  • Objective: The study was conducted to determine the effects of body weight (BW) and fiber sources on nutrient digestibility, fiber fermentation and short chain fatty acids (SCFA) concentration in different intestinal segments of growing pigs fed high-fiber diets. Methods: Nine barrows with initial BW of 25.17±0.73 kg and 9 barrows with initial BW of 63.47±2.18 kg were allotted to a duplicate 9×2 Youden Square design with 3 dietary treatments and 2 periods. The dietary treatments were formulated with 3 different high-fiber ingredients: corn bran, sugar beet pulp, and soybean hulls, respectively. Each diet was fed to 3 barrows with different stage of BW in each period. Results: There were no differences in the apparent ileal digestibility (AID) of most nutrients between pigs at different BW stages. Pigs at 60 kg had greater (p<0.05) apparent total tract digestibility (ATTD) of total dietary fiber (TDF), soluble dietary fiber (SDF) and insoluble dietary fiber (IDF), and had greater (p<0.05) hindgut disappearance of IDF and cellulose than pigs at 25 kg. The acetate, propionate and total SCFA concentrations in ileal digesta and feces of pigs at 60 kg were greater (p<0.05) than those of pigs at 25 kg. In addition, fiber sources affected (p<0.05) the AID of gross energy (GE), organic matter (OM), ether extract (EE), crude protein, SDF and hemicellulose, the hindgut disappearance and ATTD of dietary fiber components, the lactate and propionate concentrations in ileal digesta and the butyrate, valerate and total SCFA concentrations in feces. There were interactions (p<0.05) between BW and fiber sources on the AID of GE, OM, EE, SDF, hemicellulose, the ATTD of EE, TDF, and IDF, and the hindgut disappearance of SDF and hemicellulose. Conclusion: Increasing BW mainly improved the digestibility of dietary fiber fractions, and the dietary fiber sources influenced the digestibility of almost all the dietary nutrients in growing pigs.

  • This work was carried out to study the chemical and fatty acid composition of Longissimus muscle (LM) of crossbred young bulls finished in a feedlot. After weaning (at 8 months old), the bulls were kept in a feedlot for 180 days. The bulls were kept in individual pens and fed (twice daily) with corn silage, soybean hulls, cracked corn, limestone, urea and mineral salt. The bulls were slaughtered with a final weight of 464 kg. Forty bulls were used: 10 Caracu (CAR), 10 Canchim (CAN), 10 Caracu vs. Charolais (CCH) and 10 Canchim vs. Aberdeen Angus (CAA). The percentages of moisture, ash, crude protein, total lipids, as well as the fatty acid composition, were measured in the LM. The moisture percentage was lower (p<0.05) for bulls from CAA genetic group (71.2%) in comparison to bulls from CAR (74.2%), CAN (74.9%) and CCH (74.7%) genetic groups. On the other hand, there was no difference (p>0.05) among bulls from CAR, CAN and CCH genetic groups. Ash percentage was lower (p<0.05) for CAR bulls (0.96%) in comparison with the other genetic groups. There was no difference (p>0.05) among CAN, CCH and CAA genetic groups. Similarly, there was no difference (p>0.05) in crude protein among the different genetic groups. Total lipids percentage was higher (p<0.05) for CAA bulls (5.35%) and lower (p<0.05) for CAN (1.85%) and CCH (1.41%) genetic groups. Genetic group has little effect on the fatty acid composition of Longissimus muscle of bulls. However, CLA (C 18:2 c-9 t-11) percentage was higher (p<0.05) for CAR (0.33%) and CCH (0.37%) in comparison to CAN (0.27%) and CAA (0.29%) genetic groups. Saturated, monounsaturated and polyunsaturated fatty acids, n-6 and n-3 percentages did not differ (p>0.05) among genetic groups. PUFA/SFA ratio ranged from 0.10 to 0.15, with no difference (p>0.05) among genetic groups. Similarly, n-6/n-3 ratio ranged from 12.6 to 16.3, without difference (p>0.05) among genetic groups.
