Replacement of fish oil in plant‐based diets for Pacific white shrimp,Litopenaeus vannamei,by stearine fish oil and palm oil

Stearine fish oil (SFO) and palm oil (PO) have emerged as promising alternatives for the replacement of fish oil (FO) in aquafeeds. This study evaluated the replacement of FO with alternative oils in practical diets for Litopenaeus vannamei. In a clear brackish water study (14.1 g/L) utilizing shrimp (0.29 ± 0.02 g, initial weight), FO was replaced by SFO at inclusion ratios of 100:0, 75:25, 50:50, 25:75, and 0:100 (FO:SFO) and PO as 90% of FO. After 55 days, no significant differences (p < 0.05) in final weight, growth, or survival of shrimp were observed. A second trial (8 weeks) in low‐salinity water (2.1 g/L) with shrimp (0.92 ± 0.02 g, initial weight) evaluated diets with 100% FO, 100% SFO, 90% PO, 90% soybean oil (SO), or 90% flaxseed oil (FXO) as a replacement for FO and four commercially produced diets with 2% of FO, SO, PO, or FXO. One treatment received half rations of the commercial FO diet, and one treatment was based entirely on natural productivity. Results show that the fatty acid profiles of the tail muscle conformed to the lipids of the feed, and highly unsaturated fatty acids (HUFAs) were preserved. Following 8 weeks of culture, there were no significant differences in production performance.

进口木地板坯料应注意的问题

本文提出了进口木地板坯料时应考虑南北气候差异及木材密度等材性差异来确定留有不同的加工余量，并建议海关按照国际惯例制定以净尺寸材积作为计税材积的标准，避免各港口实行不同征税标准，给企业进口地板坯料带来诸多困难。该建议已引起海关总署重视，并委托国家林业局起草单耗标准。     

GI PiCO2: Tissue Specific Monitoring For Improving Patient Outcomes

Improvements in human patient monitoring despite their development in animals, do not always find their way into veterinary clinical use due to financial constraints. Gastrointestinal intraluminal CO₂ partial pressure (Gip₁CO₂) monitoring, however, is not only proving very beneficial in human trauma and critical patient care but is also very likely to become relatively inexpensive. By providing information on the perfusion adequacy of a high risk, critically important tissue, the GI mucosa, GI P₁CO₂ monitoring offers an easily accesible indicator of the efficacy and adequacy of resuscitative interventions. The potential for decreasing morbidity and mortality is enormous. Therefore, the practicing veterinarian should become familiar with GI P₁CO₂ monitoring theory and technology so he or she can be better prepared to incorporate it into practice when in becomes available.     

高等农业教育在重庆全面建设小康社会中的地位与作用研究

重庆作为年轻的直辖市，城镇化程度低，是典型的农业大市。因此，没有农业的现代化也没有整个重庆的现代化；没有广大农村地区的全面小康就谈不上整个重庆的全面小康。文章针对重庆特别是农村实际，通过分析重庆农村能否实现全面小康，对整个重庆全面小康的影响，破解农村问题的基本思路；以及针对重庆教育特别是高等农业教育的发展现状、高等农业教育在全面建设农村小康社会中的地位与作用作了进一步的研究。探索出高等农业教育在重庆全面建设农村小康社会中地位特殊、作用重要，发展高等农业教育的任务紧迫。
