This study was aimed to examine the antibacterial and antioxidative properties of seven edible plants from Thailand develop alternative antibiotics as feed additives. The include Citrus aurantifolia Swingle (Lime) fruits its leaves, Sesbania grandiflora L. (Agati sesbania) Piper sarmentosum Roxb (Wild betal) Curcuma domestica Valeton (Turmeric) roots, Morinda citrifolia (Beach mulberry) Cassia siamea britt (Siamea cassia) Cocos nucifera (Coconut) peels. were extracted by methanol, n-hexane,...
The present study was conducted to investigate the effect of a multi-protease on production indicators broiler chickens fed crude protein and amino acid deficient-diets for 35 days immediately after hatch. A total 448 one-day-old Ross 308 male chicks were allocated in completely randomized design into one eight dietary treatments (positive control [PC], negative [NC: minus 0.5% from PC, 2% lysine, methionine, threonine methionine plus cysteine], extreme [ENC: 1% 4% 150 or 300 g per ton [e....
The effect of intravenous infusion acetate, propionate and butyrate (0, 3, 10, 30μmol kg-1 min-1 over 40min) on the secretion growth hormone (GH), insulin glucagon in response to hormone-releasing factor (GRF) injection (0.25μg/kg, 10min after onset acid infusion) was determined six sheep. GRF caused a marked increase plasma GH at every dose each acid. unaffected by an acetate. basal levels insulin, glucose were unchanged acetate infusion. markedly suppressed dose-dependent manner....
A VFA mixture solution containing acetate, propionate and butyrate (the molar ratio of n-butyrate = 61.7:24.3:14.0) was infused into the rumen at various rates (53.5, 107 214 mumol kg-1 min-1) over 6 h to examine effects on basal growth hormone-releasing factor (GRF, 0.25 micrograms kg-1)-induced increase in secretion GH, insulin, glucagon somatostatin (SRIF) five castrated male sheep. Intraruminal infusion 18-h-fasted animals 53.5, min-1 finally raised total intraruminal concentration from...
본 연구에서는 Ross strain-208 브로일러 수컷 36,800 수를 기본 사료만 급여한 대조구와 사료에 0.3% 점토 광물질 발효 산물을 첨가 처리구로 나누어 5주간 사양 시험을 시행하였고, 사육 후 육계의 최종 체중 및 일당 증체량, 육성율, 사료 섭취량, 효율, 생산 지수 등에 미치는 영향을 조사하였다. 그 결과, 체중은 처리구가 대조구에 비해 유의성은 없으나 약 18.5% 증가하였고, 증체량은 18.2% 유의하게 증가한 것으로 나타났다(p<0.05). 섭취량과 대조구보다 21.4% 효율은 2.7% 나타났다. 특히 육성율과 지수는 각각 4.4%와 4.9% 증가하였다(p<0.05). 또, ND(뉴캐슬병)와 IBD(전염성 F낭병)의 백신을 음용 투여하였을 때의 항체 역가는, 0.3 % 산물 첨가구가 13.8%와 15.7% 높은 이상의 결과로부터 산물의 첨가급여는 생산성과 면역 기능을 증진시켜 항생제를 저감한 친환경적인 고품질 육계 생산에 도움이 될 사료되었다.

This study was conducted to evaluate the effects of high-temperature stress on dairy cow productivity and correlation between rumen sensors. The data were collected temperature, humidity, milk productivity, components, blood sensor from 125 cows during experimental period (1 May 2020 30 October 2020). High-temperature evaluated based temperature-humidity index (THI). correlations stress, analyzed using SAS R programs. THI ranged 46.9 81.0 period, a significant decrease observed in production August (
ニホンジカおよびヒツジに,体重の2%のアルファルファ•ヘイ•キューブを制限給餌した時の飼料片の消化管内通過速度および消化率を,夏期(7月)と冬期(2月)に測定して比較した.両動物種の消化管内通過速度は夏期と比較して冬期に有意に速くなり,飼料消化率は有意に低下した.また,ヒツジと比較してニホンジカの消化管内通過速度は有意に速く,消化率は有意に低かった.以上の結果から,制限給餌下において,両動物種の飼料消化率には季節変動および種差が認められ,その原因として消化管内通過速度が関与している可能性が考えられる.
본 연구는 식물성 phytase 처리수준이 산란계의 생산성에 미치는 영향 및 인 이용률에 영향을 검토하기 위하여 실시하였다. NRC 사양표준의 유효 요구량을 충족시킨 대조구와 무기태인 사용량을 50%로 제한한 처리구로 나누고, 각각의 처리구에 phytase를 각각 0.05%, 0.1% 0.2% 첨가하였다. 58주령의 갈색 산란계(ISA-Brown) 240수를 공시하여 총 6주간 사양실험을 실시하였고 산란종계를 이용하여 질소의 이용성을 측정하였다. 그 결과를 요약하면 다음과 같다. 1. 50% 수준에서 phytase의 첨가에 따른 일당증체량, 산란율의 저하는 나타나지 않았다. 2. 0.05% 첨가수준에서 일시적으로 난각질 저하 현상이 나타났으나 이상 첨가수준에서는 난각질의 변화가 관찰되지 3. 효소의 첨가수준이 증가함에 따라 P 배설량의 감소와 이용률이 개선되었다(P<0.05). 4. 첨가는 성적 저하없이 사료내 무기태인의 줄일 수 있음이 시사되었다.
