10Investigation of the stability and hydrodynamics of Tetrosomus gibbosus carapace in different pitchangles显示文摘In this paper,stability properties of Tetrosomus gibbosus have been experimentally and numerically studied in pitching movements.This fish lives in southern offshores of Iran.Boxfishes usually live in extremely turbulent parts of seas and oceans,with high stability and maneuverability that has caught the attention of scientists.Their body shape let them swim with a quite rapid speed.Studies on Boxfishes have had influences on automotive and marine industries.The CAD file of the boxfish was created using optical CMM.Also a model was built and tested in a subsonic wind tunnel and a numerical study was conducted in virtual wind tunnel.The experimental results are consistent with the numerical ones and also support the findings of other studies on similar boxfishes.These results show that the flow around the fish,which is a consequence of its body shape,tries to maintain the stable position of the fish by resisting against the external force tilting the fish from its stable horizontal posture.The ventral and dorsal keels of the boxfish generate column-like vortices in horizontal direction which play an imperative role in maintaining the stability of the fish.Mahyar Malekidelarestaqi Alireza Riasi Hadi Moradi Mohammad Samadpour 2019Journal of Hydrodynamics2019,31,2:0
11Performance and plasma concentration of metabolites in transition dairy cows supplemented with vitamin E and fat显示文摘The objective of this study was to evaluate the effects of vitamin E(VE; 1 500 or 3 000 international units(IU) d^(–1)) and fat(2% of dry matter calcium salt of soybean oil) supplementation during the transition period on feed intake, milk yield and composition and blood metabolites of dairy cows. 48 multiparous Holstein cows were randomly assigned into one of four treatments in a 2×2 factorial arrangement of vitamin E and supplemental dietary fat during the transition period. Treatments were: 1) 1 500 IU d^(–1) vitamin E without fat supplementation(1 500VE–F); 2) 1 500 IU d^(–1) vitamin E with fat supplement(1 500VE+F); 3) 3 000 IU d^(–1) vitamin E without fat supplementation(3 000VE–F); and 4) 3 000 IU d^(–1) vitamin E with fat supplement(3 000VE+F). Dietary treatments were initiated at approximately 28 d before expected calving dates and continued through 28 d postpartum. Dry matter intake(DMI) was unaffected(P>0.05) by prepartum treatment. Regardless of vitamin E supplementation, DMI was greater(P<0.01) in fat-supplemented cows compared with un-supplemented cows(19.60 vs. 18.45 kg d^(–1); SEM=0.42) during the postpartum period. Energy balance and body weight were not affected(P>0.05) by treatments. Postpartum diets had no significant effect on milk yield or milk composition. Plasma concentrations of non-esterified fatty acids, glucose, and insulin were not affected(P>0.05) by treatments. Regardless of vitamin E supplementation, plasma β-hydroxybutyrate concentration was greater(P<0.05) in fat-supplemented cows compared with un-supplemented cows during the postpartum period. These results showed no indication of positive effects on lactation performance associated with vitamin E and dietary fat supplement in transition cows.Rohollah Amirifard Mohammad Khorvash Masiholla Forouzmand Hamid-Reza Rahmani Ahmad Riasi Mohammad Malekkhahi Mojtaba Yari Morteza Hosseini-Ghaffari 2016Journal of Integrative Agriculture2016,15,5:0
12瘤胃维生素丸缓释多种维生素对高热条件下哺乳期高产奶牛生产繁殖性能的影响显示文摘试验旨在探索高温条件下,饲粮中添加瘤胃维生素丸,缓释多种维生素对泌乳期荷斯坦奶牛血液代谢物和生产繁殖性能的影响。试验期间,最高温湿指数(THI)达到77.7。50头高产奶牛随机分到两个试验组中:1组为试验组,饲粮中补充维生素丸;2组为空白对照组,饲粮中无添加。每个维生素丸含有矿物质(铜16.2 g、硒0.251 g、钴0.236 g、碘0.497 g、锰8.28 g、锌13.32 g)和维生素(维生素A 545.6×103U、维生素D3 109.1×106U、维生素E 1 092 U)。试验结果表明,与对照组相比,饲粮中添加维生素丸可使奶牛产奶量有增加趋势(P=0.07),显著提高乳脂肪含量(P=0.03),极显著增加乳蛋白含量和非脂乳固体(SNF)含量(P<0.001)。饲喂维生素丸可使产后期奶牛血浆中未酯化脂肪酸(NEFA)含量降低,但与对照组相比差异不显著(P=0.09)。饲喂维生素丸可使空怀期(产犊后时期)显著缩短(P=0.02),在第5次人工授精时引发的妊娠反应显著增强(P=0.01)。试验结果表明,补充缓释矿物质和维生素超过NRC推荐标准时,显著提高了高温环境下的高产奶牛生育和生产性能。Khorsandi S Riasi A Khorvash M Mahyari S A Mohammadpanah F Ahmadi F 2016饲料博览2016,0,5:0
