There was no impact on milk volume or other components and only a slight increase in dry matter intake, which resulted in no effect on feed efficiency in terms of energy-corrected milk.With butterfat doubling in value to average $2.30 per pound over the past three years, a 0.2% increase in butterfat for an 80-pound dairy herd could mean 35 cents per hundredweight to the milk check under normal marketing conditions when milk volume and other components are unchanged.Through a check-off grant from the Pennsylvania Soybean Board, Alexander Hristov, Ph.D., PAS, Penn State professor of dairy nutrition, led a project to evaluate dairy ration performance of three soybean meal sources: conventional, high linoleic extruded soybean meal; extruded Plenish (DuPont Pioneer) high oleic soybean meal; and whole, heated Plenish high oleic soybeans. High oleic soybeans have been grown commercially in the United States for five seasons, and are grown in Pennsylvania and 11 other states.The study was done with extruded soybean meal versus conventional solvent extraction because more of the soybean oil is retained with the extrusion process. Substituting the extruded Plenish variety soybean meal for conventional extruded soybean meal requires no adjustment in dairy rations, according to the study.“We were surprised with such an obvious (0.2%) milkfat percentage increase. The mechanism we think is taking place is the higher level of oleic fatty acids in the Plenish high oleic soybeans versus linoleic fatty acids in the conventional soybeans, and a reduction in the already small level of trans fatty acids in milk,” Hristov said.Not only did the high oleic variety raise milk butterfat content over conventional soybean meal, it changed the composition of the milkfat. The increase in heart-healthy monounsaturated fats and some significant decreases in trans fatty acids in the milk are noteworthy for consumers.“The 17% reduction in trans fatty acids is significant,” Hristov said. “These are the harmful fatty acids consumers want to avoid and it went from 3.36% of the total percentage of milkfat to 2.80% in the Plenish diets. Even though those levels of trans fatty acids are relatively low in milk to begin with, the Plenish diets still decreased them further, which is beneficial.“If soybean growers grow more high oleic beans versus conventional because it benefits human food products more, there will be more soymeal going into animal feed with this profile. But the benefits are only realized if the residual fat is in the soymeal (via extrusion or whole roasting). Although this wasn’t studied, it can be assumed that the benefit is close to zero if solvent extraction processes are used versus extrusion.”Hristov describes the research and findings in his paper published in the September 2015 Journal of Dairy Science.

first_imgBijay Bhuyan, a farmer in Odisha’s Bhadrak district, has been living with his family in their ancestral home for years, but he had no inkling that he was sharing it with cobras.To his utter surprise, he found 106 juvenile cobra snakes in the house in Paikasahi village on Friday. Efforts are on to retrieve more reptiles from an ant-hill that has come up adjacent to an earthen wall. Fellow villagers have thronged Mr. Bhuyan’s house to see the young reptiles.“Family members had come across snakes around their house on several occasions,” said Seikh Mirza, a member of Snake Helpline, a voluntary forum that helps rescue snakes in distress. “Their religious belief did not allow them to dismantle the ant hill.”“We have rescued 99 young cobras. Six snakes were found dead. As many as 19 eggs have also been spotted,” he said.last_img read more

first_imgA PWD junior engineer, who was allegedly forced by a newly elected BJD MLA in Odisha to do sit-ups in public, on Friday claimed the legislator had also asked an executive engineer to slap him, even as the police registered a case against the lawmaker. The alleged “rowdyism” of Saroj Kumar Meher, first-time MLA from Patnagarh in Bolangir district, also triggered a row with the Opposition BJP coming down heavily on the BJD government and demanding immediate arrest of the lawmaker and the Congress condemning the incident. Mr. Meher, who drew flak after a video purportedly showed him forcing a PWD junior engineer to do sit-ups in public went viral, on Thursday apologised for his action, claiming he did so to assuage public anger. Later on Thursday, the engineer’s wife lodged a complaint with the police against the MLA, accusing him of publicly humiliating her husband.last_img read more

From digital twins for virtual commissioning to system-level models for complex engineering design projects, MapleSim helps organizations reduce development risk, lower costs, and enable innovation. The latest release provides new tools for developing digital twins, in addition to greater connectivity with other modeling tools, and expanded modeling scope.MapleSim is used across a wide variety of applications and industries, including the creation of physics-based digital twins for virtual commissioning. Identifying the optimal motor size required to drive a mechanism is one of the most important goals of simulation with digital twins, and MapleSim 2018 provides tools that make this task easier. The new 1-D Motion Generation App allows engineers to create motion profiles that adhere to defined velocity and acceleration constraints. They can define the desired motion of the joints, and then run the simulation to discover the torques and forces required to create that motion.  This information can then be used to correctly size the motors, ensuring optimum performance at minimal cost.MapleSim is a natural environment for modeling multidomain systems that supports the rapid creation and testing of initial concepts. With MapleSim, engineers can try out more ideas in less time, identify and prevent unexpected interactions between different domains, and generate computationally efficient models. New features in MapleSim 2018 further enable this work with more connectivity options and increased modeling scope. MapleSim 2018 provides greater toolchain connectivity with the ability to import models from even more software tools.  With the expanded FMI support, engineers can import models defined using FMI 2.0 Fixed-Step Co-Simulation, as well as FMI Model Exchange. Other improvements include enhanced Modelica support for easy access to more 3rd party component libraries inside MapleSim. In addition, the MapleSim Heat Transfer Library from CYBERNET offers improved tools for studying heat transfer effects and preventing overheating, while the MapleSim Hydraulics Library from Modelon and MapleSim Pneumatics Library from Modelon add-ons can both now take into account temperature effects during simulations. MapleSim is available in English, Japanese, and French.Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Tools & Software last_img read more
