在天山畜牧昌吉生物工程有限责任公司榆树沟良种繁育基地,土壤较瘠薄,盐碱较重的地段,进行了苜蓿配合施肥试验。结果表明:配合施肥可提高杂花苜蓿干草产量,过磷酸钙与硫酸钾配合施用干草产量最高为15 860.80 kg/hm2,高于对照36.81%;同时也提高了苜蓿粗蛋白含量,改善了苜蓿品质。尿素,过磷酸钙及硫酸钾配合施用时,前两茬草粗蛋白含量分别为19.12%和19.90%,高于对照的17.4%和12.8%;提高了苜蓿种植的经济效益,尿素与过磷酸钙配合施用时效果最好,净增1 826.55元/hm2。  相似文献   

Reproductive and Endocrine Characteristics of Delayed Pubertal Ewe-Lambs after Melatonin and l-Tyrosine Administration     

KA El-Battawy 《Reproduction in domestic animals》2006,41(1):1-4

The investigation was carried out to study the impact of melatonin and L-tyrosine administration on the onset of cyclicity in delayed pubertal ewe-lambs. Fifteen delayed pubertal ewe-lambs (age >16 months) were used in this study after being assigned randomly into three groups. In the first group (melatonin treated group, n = 5), each lamb was administered 3 mg melatonin orally at 16:00 hours from 1 July to 15 September while in the second group (L-tyrosine treated group, n = 5), each lamb was administered L-tyrosine at the level of 100 mg/kg b.w. as a single oral dose. The third group (n = 4) served as control. Lambs were exposed to mature, fertile rams daily and blood samples were collected twice weekly. The progesterone concentrations (P4 evaluations) were significantly higher (p < 0.05) in treated groups than the control group. Ovarian activity, assessed by P4 evaluations, showed that all animals in the first group came in oestrus and from them four got pregnant (80%) while in the second group, only three lambs came in heat and from them two became pregnant (40%). On the contrary, none of the control lambs showed oestrus. In conclusion, this study confirmed that the oral administration of melatonin and L-tyrosine played an essentially physiological roles to induce cyclicity in delayed pubertal ewe-lambs and improved their reproduction.  相似文献   

不同精粗比全混合颗粒饲粮对母羊营养物质表观消化率、氮代谢和能量代谢的影响   总被引：4，自引：0，他引：4

本试验研究了不同精粗比全混合颗粒饲粮对母羊营养物质表观消化率、氮代谢和能量代谢的影响,以确定母羊饲粮适宜精粗比[或中性洗涤纤维(NDF)水平]。试验采用单因素完全随机区组设计,将30只体况良好、8月龄、体重相近的杂交母羊(萨福克羊×阿勒泰羊)随机分为6个处理,每个处理5只羊,分别饲喂6种不同精粗比(85∶15、70∶30、55∶45、40∶60、25∶75、10∶90)的全混合颗粒饲粮。预试期10 d,消化代谢试验18 d,呼吸测热试验2 d。结果表明:1)全混合颗粒饲粮精粗比对母羊干物质(DM)、有机物(OM)和NDF表观消化率均产生了极显著影响(P<0.01),DM和OM表观消化率随精粗比的上升而升高,精粗比为55∶45的饲粮NDF表观消化率最高,与精粗比为85∶15和70∶30的饲粮差异不显著(P>0.05)。2)消化氮随着精粗比的上升而升高,过高或过低精粗比均不利于氮的沉积,精粗比为55∶45时,母羊对氮的利用效率最高。3)消化能、代谢能、总能消化率和总能代谢率均随着精粗比的上升而出现极显著的升高(P<0.01)。在本试验条件下,母羊对精粗比为70∶30和55∶45(NDF水平分别为37.78%和45.80%)的全混合颗粒饲粮消化吸收较好。  相似文献   

Diameter-Selective Raman Scattering from Vibrational Modes in Carbon Nanotubes   总被引：1，自引：0，他引：1

Single wall carbon nanotubes (SWNTs) that are found as close-packed arrays in crystalline ropes have been studied by using Raman scattering techniques with laser excitation wavelengths in the range from 514.5 to 1320 nanometers. Numerous Raman peaks were observed and identified with vibrational modes of armchair symmetry (n, n) SWNTs. The Raman spectra are in good agreement with lattice dynamics calculations based on C-C force constants used to fit the two-dimensional, experimental phonon dispersion of a single graphene sheet. Calculated intensities from a nonresonant, bond polarizability model optimized for sp2 carbon are also in qualitative agreement with the Raman data, although a resonant Raman scattering process is also taking place. This resonance results from the one-dimensional quantum confinement of the electrons in the nanotube.  相似文献
