| 1 | 益生元和益生菌显示文摘益生元是一种不易被消化的可食用物质,通过选择性地刺激肠道中有益细菌的生长,从而对宿主产生有益的影响。益生菌是有益微生物的活菌制剂。有关益生元和益生菌的生长性能的试验结果并不一致。需要更多的研究来证明益生元和益生素在猪日粮中使用的合理性。 | 张婵娟 Jay Y.Jacela Joel M.De Rouchey Mike D.Tokach | 2011 | 国外畜牧学(猪与禽)2011，，6： | 4 |
| 2 | 使用能量利用效率评估豆粕对于玉米的相对能值及其对保育仔猪生长性能的影响显示文摘试验旨在评估豆粕相对于玉米的能值,并测定提高日粮中豆粕水平对保育仔猪的影响。总计2233头猪(品种PIC337×1050),初始平均体重10.98 kg,分配到92个饲养栏中,每个饲养栏20~27头仔猪,性别混合。断奶后,所有仔猪饲喂21 d相同日粮,按完全随机试验设计,根据体重将仔猪分为不同处理组。处理组日粮分别含21%、27%、33%、39%豆粕,并通过改变饲料氨基酸水平和玉米水平来配制平衡日粮,试验期饲喂21 d。仔猪称重并测定采食量,计算平均日增重(ADG)、平均日采食量(ADFI)、料重比(F/G)和热量效率(CE)。采用SAS的GLIMMIX程序,以随机效应和处理组作为固定因子分析数据。建立单自由度对比来检测随豆粕水平增加的线性和二次效应。对ADG有二次效应趋势(P=0.090),当豆粕水平为33%时有显著提高。随着日粮豆粕水平提高对于ADFI有降低趋势(线性,P=0.092)。随着日粮豆粕水平提高,仔猪的料重比呈提高趋势(二次,P=0.066),33%豆粕处理组仔猪的料重比最高,但39%豆粕处理组又回到对照组水平。随着豆粕水平提高,CE呈增加趋势(线性,P=0.001;二次,P=0.065)。以CE方式测定4个数据点评估豆粕能值为玉米能值的105.4%,11.78 MJ/kg净能。当去除39%豆粕处理组的CE值时(含39%豆粕水平时呈二次趋势),仅使用CE应答的线性趋势部分来计算豆粕能值为玉米能值的121.1%,净能为13.54 MJ/kg。综上,试验结果表明饲喂豆粕水平达33%时可提高ADG、F/G和CE,豆粕能值为玉米能值的105.4%~121.1%,这要比当前推荐的豆粕能值为玉米能值78%数据要高很多。该结果意义重大,因为它增加了日粮配方中豆粕的能值。 | 何颖(编译) Henrique S.Cemin Mike D.Tokach Steve S.Dritz Jason C.Woodworth Joel M.De Rouchey Robert D.Goodband | 2020 | 猪业科学2020，37，3： | 1 |

| 4 | 种猪营养和管理推荐措施显示文摘母猪妊娠期营养和管理
当为妊娠母猪制定饲喂方案时,要记住该营养策略的总体目标:(1)使母猪在分娩时达到适合的体况:(2)尽可能提高母猪繁殖性能(分娩率和窝产仔数):(3)在最低的可能成本下满足母猪营养日需要量(以每天每头母猪的成本来衡量)。 | Joel M.DeRouchey Steve S.Dritz Robert D.Goodband Jim L.Nelssen Mike D.Tokach 冯占雨 | 2010 | 今日养猪业2010，，1： | 0 |
| 5 | 纤维源和粗蛋白水平对保育猪生长性能和粪便微生物菌群的影响显示文摘仔猪断奶后腹泻(PWD)是一种通常发生在仔猪断奶后2周的疾病,可以通过对猪只反复排泄松散的水样粪便进行诊断。这种疾病致使猪只生长缓慢、脱水、营养物质消化率降低,严重情况下可能会出现猪只死亡,给生猪产业带来重大的经济损失。近年来,针对各种PWD缓解剂和促生长添加剂(例如药物锌制剂和抗菌物质)都颁布了限制和禁令,因为它们在商业生产环境中阻碍了猪只健康及生产性能和对环境产生污染。 | 何颖(编译) Kelsey L.Batson Alison C.Neujahr Thomas Burkey Samodha C.Fernando Mike D.Tokach Jason C.Woodworth Robert D.Goodband Joel M.DeRouchey Jordan T.Gebhardt Hilda I.Calderón | 2022 | 猪业科学2022，39，6： | 0 |
| 6 | 种猪营养和管理推荐措施显示文摘日粮中需要添加铬和L-肉碱吗?
已有研究表明,一些通常在生长-肥育猪日粮中无需添加的维生素和矿物质元素会改善母猪的繁殖性能。这些营养素包括生物素、胆碱、叶酸,最近发现铬(微量元素)和L-肉碱也属于此类。 | Joel M.DeRouchey Steve S.Dritz Robert D.Goodband Jim L.Nelssen Mike D.Tokach 冯占雨 | 2010 | 今日养猪业2010，，2： | 0 |
| 7 | Estimate of the energy value of soybean meal relative to corn based on growth performance of nursery pigs显示文摘Background:Two experiments were conducted to determine the effects of increasing amounts of soybean meal(SBM)in swine diets and estimate the energy value of SBM.Methods:A total of 2233 pigs(PIC 337×1050,Hendersonville,TN)and 3796 pigs(PIC 359×C40),initially 11.0 kg and 17.6 kg body weight(BW),were used in Exp.1 and 2,respectively.In Exp.1,pigs were placed in 92 pens each containing 20 to 27 pigs.In Exp.2,pigs were placed in 84 pens each containing 37 to 43 pigs.Treatments were assigned in a randomized complete block design with BW as the blocking factor.Dietary treatments consisted of 21%,27%,33%,or 39%SBM in Exp.1 and 17.5%,22%,26.5%,31%,35.5%,or 40%SBM in Exp.2,obtained by changing the inclusion rate of feed-grade amino acids and corn grain.For Exp.1,representative samples of corn grain,SBM,and distillers dried grains with solubles were analyzed for total AA content prior to diet formulation.For Exp.2,diets were formulated using NRC(2012)nutrient loadings.Treatment diets were fed for 21 and 22 d(Exp.1 and 2)and there were 23 replicates in Exp.1 and 14 replicates in Exp.2.Pigs were weighed and feed disappearance measured weekly to calculate average daily gain(ADG),average daily feed intake(ADFI),gain-to-feed ratio(G:F),and caloric efficiency(CE).Data were analyzed with block as a random effect and treatment as a fixed effect,and contrasts were constructed to test the linear and quadratic effects of increasing SBM.Results:In Exp.1,there was a tendency(linear,P=0.092)for a decrease in ADFI as SBM increased.There was a tendency(P=0.090)for a quadratic response for ADG,with a decrease in ADG observed with 39%SBM inclusion.Pigs fed diets with increasing SBM had a tendency(quadratic,P=0.069)for an increase in G:F up to 33%SBM and an improvement(linear,P=0.001;quadratic,P=0.063)in CE with increasing SBM.Using CE to estimate the energy of SBM relative to corn,a value of 105.4%of corn energy or 2816 kcal/kg NE was determined using all data points.When removing the CE value of the 39%SBM treatment due to the quadratic tendency,SBM was estimated to have 121.1%of corn energy or 3236 kcal/kg NE.In Exp.2,there was a decrease(linear,P=0.001)in ADFI.Pigs fed increasing SBM had a tendency(linear,P=0.065)for reduced ADG but an improvement(linear,P=0.001)in G:F and CE as SBM increased.The energy value of SBM was estimated as 124.7%of corn energy or 3332 kcal/kg NE.Conclusions:The results suggest that feeding increasing levels of SBM improves G:F and CE.The energy value of SBM was estimated to be between 105%and 125%of corn,which is much greater than the NRC(2012)would indicate. | Henrique S.Cemin Hayden E.Williams Mike D.Tokach Steve S.Dritz Jason C.Woodworth Joel M.DeRouchey Robert D.Goodband Kyle F.Coble Brittany A.Carrender Mandy J.Gerhart | 2020 | Journal of Animal Science and Biotechnology2020，11，3： | 0 |
| 8 | 霉菌抑制剂、霉菌毒素结合剂和抗氧化剂显示文摘饲料原料如谷物易于霉菌的生长及霉菌毒素的污染。在日粮中添加霉菌抑制剂,如有机酸可防止霉菌生长,但是不能有效地预防霉菌毒素的污染。向日粮中添加霉菌毒素结合剂可防止猪通过采食受污染的饲料而摄入毒素。常见的霉菌毒素结合剂能够有效地预防黄曲霉毒素的污染,而对其他霉菌毒素的作用很有限。在含有易于酸败(由于脂肪含量较高)的饲料原料的日粮中,添加抗氧化剂看来是可行的。 | 黄玲 Jay Y.Jacela Joel M.De Rouchey Mike D.Tokach Robert D.Goodband Jim L.Nelssen David G.Renter Steve S.Dritz | 2011 | 国外畜牧学(猪与禽)2011，，6： | 0 |
| 9 | 植酸酶显示文摘植酸酶是一种能够提高猪日粮中磷的利用率的酶。它可以降低日粮中所需磷的添加量。由于提高了日粮磷的利用率,因此减少了粪便磷的排放量。植酸酶在较长的贮存期间容易失活。 | 徐淑玲 Jay Y.Jacela Joel M.De Rouchey Mike D.Tokach | 2011 | 国外畜牧学(猪与禽)2011，，6： | 0 |
| 10 | 植物提取物饲料添加剂(植生素或植物药物)显示文摘植物提取物饲料添加剂是从植物中提取的一类活性物质。在猪日粮中添加植物提取物的潜在益处现在还没有得到充分的证实。目前的研究结果显示,植物提取物饲料添加剂对动物生长的有益影响仍不足以与饲用抗生素相比。 | 苏良科 Jay Y.Jacela Joel M.De Rouchey Mike D.Tokach | 2011 | 国外畜牧学(猪与禽)2011，0，6： | 0 |
| 11 | 考虑实际日粮因素以优化生长肥育猪养殖利润显示文摘在猪的生产过程中,75%~80%的饲料用于生长育肥期。因此,育肥阶段对养猪生产者而言具有重要的经济影响。本文通过研究能量水平、氨基酸比例、钙磷含量及其比例以及维生素、微量元素、盐以及包括添加剂在内的其他养分的水平,以优化生长育肥猪养殖利润。 | Mike D.Tokach Henrique S.Cemin Joel M.DeRouchey Robert D.Goodband Jason C.Woodworth Steve S.Dritz | 2020 | 饲料工业2020，41，8： | 0 |
