1饲料中添加蛋白酶对肉鸡性能、养分利用率、肠道形态和胴体品质的影响显示文摘试验在饲喂玉米、高粱为主的肉鸡日粮中补充大豆,并添加蛋白酶,研究蛋白酶对肉鸡性能、养分消化率、肠道形态和胴体品质的影响。试验选取1日龄AA肉仔鸡(43.8±1.31 g)256只,均为公鸡,随机分配到2×2试验设计方阵中,方阵包括正常组(玉米组和高粱组)和蛋白酶组(空白组和添加蛋白酶150 mg·kg^(-1)的试验组)。试验1~21 d为第一阶段,22~42 d为第二阶段。试验结果表明,第二阶段中,日粮中添加蛋白酶极显著提高肉鸡的平均日增重(ADG,P<0.01),在整个试验过程中显著提高(P<0.05)。在各个时期,正常组对肉鸡生产性能均无显著影响(P>0.05)。19~21 d时,添加蛋白酶可显著提高肉鸡的表观代谢能(AME),干物质(DM)、总能量(GE)和养分消化率(P<0.05)。此外,日粮以高粱为主时,AME、GE消化率有降低趋势(P=0.05),氮沉积率也有降低趋势(P=0.08)。40~42 d时,日粮中添加蛋白酶可显著提高AME,DM、GE和氮沉积率(P<0.05)。21 d时,日粮中添加蛋白酶极显著增加肠绒毛高度、肠绒毛与隐窝深度比值,极显著降低十二指肠、空肠、回肠的隐窝深度(P<0.01)。42 d时,日粮中添加蛋白酶显著增加空肠肠绒毛高度、绒毛高度与隐窝深度比值,显著降低隐窝深度(P<0.05)。日粮中添加蛋白酶显著增加胸肌重、24 h p H,显著降低胸肌的滴水损失(P<0.05)。试验结果表明,饲养阶段日粮中添加复合蛋白酶可提高肉鸡ADG;在第一阶段可改善AME、DM、GE和氮沉积率和肠道形态。补充蛋白酶可提高出栏重、胸肌重和24 h pH,降低胸肌的滴水损失。低单宁高粱日粮与玉米日粮相比,对肉鸡性能的影响相近。Xu X Wang H L Pan L Ma X K Tian Q Y Xu Y T Long S F Zhang Z H Piao X S 2017饲料博览2017,0,1:2
2A review on MBE-grown HgCdSe infrared materials on GaSb(211)B substrates显示文摘We review our recent efforts on developing HgCdSe infrared materials on Ga Sb substrates via molecular beam epitaxy(MBE) for fabricating next generation infrared detectors with features of lower production cost and larger focal plane array format size. In order to achieve high-quality HgCdSe epilayers, ZnTe buffer layers are grown before growing HgCdSe, and the study of misfit strain in ZnTe buffer layers shows that the thickness of ZnTe buffer layer needs to be below 300 nm in order to minimize the generation of misfit dislocations. The cut-off wavelength/alloy composition of HgCdSe materials can be varied in a wide range by varying the ratio of Se/Cd beam equivalent pressure during the HgCdSe growth.Growth temperature presents significant impact on the material quality of HgCdSe, and lower growth temperature leads to higher material quality for HgCdSe. Typically, long-wave infrared HgCdSe(x = 0.18, cut-off wavelength of 10.4 μm at 80 K) presents an electron mobility as high as 1.3×10~5cm^2·V^(-1)·s^(-1), a background electron concentration as low as 1.6×10^(16)cm^(-3), and a minority carrier lifetime as long as 2.2 μs. These values of electron mobility and minority carrier lifetime represent a significant improvement on previous studies of MBE-grown HgCdSe reported in the open literatures,and are comparable to those of counterpart HgCdTe materials grown on lattice-matched CdZnTe substrates. These results indicate that HgCdSe grown at the University of Western Australia, especially long-wave infrared can meet the basic material quality requirements for making high performance infrared detectors although further effort is required to control the background electron concentration to below 10^(15)cm^(-3). More importantly, even higher quality HgCdSe materials on GaSb are expected by further optimizing the growth conditions, using higher purity Se source material, and implementing postgrowth thermal annealing and defect/impurity gettering/filtering. Our results demonstrate the great potential of HgCdSe infrared materials grown on GaSb substrates for fabricating next generation infrared detectors with features of lower cost and larger array format size.Z K Zhang W W Pan J L Liu W Lei 2019Chinese Physics B2019,28,1:2
