Three ways to get the most out of creep feeding pigs
2016-06-30 06:00:00| National Hog Farmer
Nursery management sets the pace for pigs’ lifetime performance, so minimizing production lags is crucial during this phase. Creep feeding is one practice you can use to optimize performance during the weaning period. Research at the Purina Animal Nutrition Center in Gray Summit, Mo., has shown creep-fed pigs ate more aggressively and experienced early and sustained gains in the nursery compared to pigs that weren’t creep-fed. read more
2 ways to limit the number of heat-related deaths from climate change
2016-06-28 18:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: By the 2080s, as many as 3,331 people could die every year from exposure to heat during the summer months in New York City. The high estimate by Columbia University scientists is based on a new model--the first to account for variability in future population size, greenhouse gas trajectories, and the extent to which residents adapt to heat through interventions like air conditioning and public cooling centers. Results appear online in the journal Environmental Health Perspectives. Researchers...

9 ways to manage heat stress on corn, soybeans
2016-06-25 00:55:00| Corn & Soybean Digest
By Suat Irmak, University of Nebraska-Lincoln Extension water resources engineer While some crops are more susceptible to heat stress during critical growth stages, both corn and soybean are also susceptible to extreme heat (and water) stress during early vegetative stages. While options are limited for mitigating the negative impact(s) of extreme heat stress on crops, there are several practical options, especially in irrigated settings. read more
Researchers find new ways to make clean hydrogen, rechargable zinc batteries
2016-06-20 05:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A Stanford University research lab has developed new technologies to tackle two of the world's biggest energy challenges -- clean fuel for transportation and grid-scale energy storage. The researchers described their findings in two studies published this month in the journals Science Advances and Nature Communications. Hydrogen fuel Hydrogen fuel has long been touted as a clean alternative to gasoline. Automakers began offering hydrogen-powered cars to American consumers last year, but only a...
