A new paper has been published in the International Journal of Food Sciences and Nutrition titled “Dietary A1 beta-casein affects gastrointestinal transit time, dipeptidyl peptidase-4 activity, and inflammatory status relative to A2 b-casein in Wistar rats”
The key findings are:
1. A1 beta casein slows down transit of food through the digestive system relative to A2 beta-casein and this is an opioid effect.
2. A1 beta-casein induces a pro- inflammatory effect in the colon which is also an opioid effect.
3. A1 beta casein relative to A2 beta-casein causes up-regulation of the enzyme DPP4 in the small intestine and this is apparently a non-opioid effect.
4. In contrast to the A1 beta-casein, there is no evidence of opioid effects from the A2 beta-casein in relation to either food transit times or pro-inflammatory effects. . . .
Benefits of collaboration – Sally Rae:
Collaboration and partnerships.
Two words mentioned often during a Federated Farmers high country field day in the upper Waitaki last week.
It was a fitting location for such an event, with what could be dubbed the ”green versus brown” debate a very hot issue in both the upper Waitaki and neighbouring Mackenzie districts.
Starting in Twizel, about 140 people travelled in a convoy of vehicles through Doug McIntyre’s dairy farm operation, on to Ohau Downs, where Kees Zeestraten is battling to bring irrigation to his property, then through Ribbonwood Station and into the Ahuriri Valley before viewing irrigation development at Tara Hills near Omarama. . .
Millions spent but no irrigation yet – Sally Rae:
Kees Zeestraten has spent close to $3 million trying to get water to irrigate Ohau Downs.
He admitted he was ”gutted” it had cost so much to get to that point – and still not have water.
Meanwhile, the flats of the 5200ha Omarama property, where he intended to do his irrigation development, were, as North Otago Federated Farmers high country chairman Simon Williamson said, ”pretty depleted”, with hieracium taking over and tussocks struggling to survive.
”In general, you would not say it’s in great health. It’s certainly not knee-high tussocks waving in the wind,” Mr Williamson said. . .
Green hues advancing in the high country – Sally Rae:
‘You wouldn’t get a better landscape. Green is as much a part of it as the tawny brown landscape in the background. What are they worrying about? It fits in.”
That was the comment of High Country Accord chairman Jonathan Wallis, after viewing the result of irrigation development on Tara Hills at Omarama.
The contrast between the green, irrigated flats of the property and the surrounding brown hills was vivid.
The 3400ha station, best known as a research property, was bought by Dave Ellis two years ago. . .
Sorting out key issues – Bryan Gibson:
Prime Minister John Key will hope his visit to China last week will have done the trick in terms of reassuring the government in that country and the buying public that our milk products are safe and our food-safety regime is robust.
A report, covered in this week’s Farmers Weekly, says New Zealand’s infant formula industry is in pretty good shape, but faces many challenges as China looks to tame the “Wild West” market that has taken shape there.
Audits of this country’s processing plants by Chinese authorities are under way and there will be many eager to know the results. . .
The Foundation for Arable Research says its foray into Australia last year is paying off.
Foundation chief executive Nick Pyke said the link with Australia enables it to leverage off the much larger investment in cropping research being carried out across the Tasman.
“We have had some involvement in programmes which are quite different for them (Australia) because of the way we grow crops here in New Zealand, so they have learnt from that”. . .
The major winners in the 2014 Auckland Hauraki Dairy Industry Awards, Bryce and Rosemarie Costar, have well achievable goals to keep them focused and heading in the right direction.
The Onewhero couple were named the region’s Sharemilker/Equity Farmers of the Year at an awards dinner in Pukekohe last night . Ngatea contract milker Simon Player was named the 2014 Auckland Hauraki Farm Manager of the Year and Paeroa dairy farm assistant Marion Reynolds won the region’s Dairy Trainee of the Year title.
Bryce and Rosemarie Costar are 55% sharemilking 300 cows on a family farm owned by Bill Costar. They won $20,200 in prizes. . .
