HNFAS study suggests global warming may contribute to poultry production losses

Chicken meat and chicken eggs are the most-consumed and widely-accepted animal protein worldwide. To meet the growing demand, advances in chicken genetics have been huge in recent decades. But the resulting improvements in poultry strains and production performance have come at a price. Today’s chickens are more susceptible to higher environmental temperatures due to a greater metabolic rate, besides the lack of sweat glands and presence of feathers.

Environmental heat stress, also a potential consequence of global warming, is a significant problem in the poultry industry. The adverse effect on poultry health and production has led to substantial economic losses in Hawaiʻi and beyond.

In a new study from the Dept. of Human Nutrition, Food and Animal Sciences, researchers are investigating several antioxidants and polyphenols to mitigate heat stress in poultry. Their findings suggest that a dietary supplementation of dried plum (rich in polyphenols) and Alpha-lipoic acid (fat and water soluble antioxidant) may impart a number of benefits. Such supplements can ameliorate the broilers’ health and production by improving the feed utilization and feed conversion ratio, antioxidants and immune-related genes, and gut microbiomes.

“It is not economical to use an air-cooling system inside a poultry house,” lead investigator Birendra Mishra points out. “Thus, with the rising issue of global warming, it is important to develop cost-effective and adoptable strategies for sustainable poultry production.”

For his related published research, graduate student Sanjeev Wasti received the 2019 Best Poster Presentation award from the Poultry Science Association and 2020 Hatchery Students of the Year award.

An Ahupua’a in Your Back Yard

TPSS is featured on Voice of the Sea

The MALAMA aquaponics program is a decade-long effort to improve the health of Waimanalo, Oʻahu, community members through a culturally grounded, multi-generational, family-based, backyard aquaponics program. MALAMA, which stands for “Mini Ahupuaʻa for Lifestyle and Mea'ai through Aquaponics” is also the focus of the latest Voice of the Sea video series. CTAHR education specialist and community coordinator Ilima Ho-Lastimosa was featured, along with UH faculty Jane Chung-Do (Public Health), Clyde Tamaru (CTAHR, retired) and Ted Radovich (CTAHR).

MALAMA involves a multidisciplinary community-academic partnership with researchers and community leaders from CTAHR, Office of Public Health Studies, and Ke Kula Nui O Waimānalo. MALAMA was first initiated in Waimānalo by Ilima in 2009 and teaches families to grow their own food using backyard aquaponics technology through Hawaiian cultural practices and values. 

The 6-month program includes a series of hands-on, family-oriented workshops to guide families to build and maintain a backyard aquaponics home system and make healthy meals and lāʻau (Hawaiian healing remedies using herbs) using the plants and fish grown in aquaponics systems.

Aquaponics has been found to resonate with Native Hawaiian communities because it utilizes a symbiotic relationship between fish and plants by effectively combining hydroponics (raising plants in water) and aquaculture (raising fish in tanks) to create a contained, sustainable food-production system that mimics the traditional Native Hawaiian ahupua‘a system of land stewardship and food sustainability.

The hands-on workshops have been held at the Waimānalo Learning Center inside the Waimānalo Research Station, where there is a community aquaponics demonstration system. As one participant in the video describes her system, “I get the food that comes out of it and it feeds my soul as well.“

FDM students’ designs will be exhibited at ITAA conference

With names like Magnificent Contemporary Hepburn and Comfey Dream, the design outfits of Jade Young and Natsuki Sugimoto will be presented Nov. 3-4 to a global audience during the upcoming International Textiles & Apparel Association’s 2021 Conference. Jade, a senior design student in the Fashion Design and Merchandising program of the Dept. of Family and Consumer Sciences, and Natsuki, a 2020 FDM graduate, will compete with other students across the country for awards and recognition in marketable designs, textiles, and sustainable designs.

“I am proud of Jade and Natsuki for their achievements,” says design mentor Minako McCarthy. “I cannot wait to see their designs exhibiting on a national stage. Their achievements will positively impact the FDM community and program, and help motivate other students in their future creations.”

Vote for your favorite in this Oʻahu 4-H contest

Turning misfortune into a new opportunity is what we do at Oʻahu 4-H. So with Covid restrictions, we decided to create a virtual “Giant Pumpkin Contest” similar to the traditional “Giant Fruit and Vegetable Contest” on the Big Island. We’ve even added a CTAHR Choice Award! That means voting for the Giant Pumpkin Contest is now open to our CTAHR community! which includes all faculty, staff, students, and community partners. That means you! Video entries will be posted on our Facebook and Instagram (@giantpumpkinoahu) pages.

Voting is open NOW until September 27 at 8:00 pm Hawaiʻi time.

The total number of “likes” for each entry on the Facebook and Instagram pages will be combined to determine the recipient of the 2021 Giant Pumpkin Contest CTAHR Choice Award! An anouncement of the recipient will be made in late September on our webpage and in CTAHR Notes.

As in years past, we’ll also have a Youth Choice Award. Youth ages 3-19 years old can vote (please have only youths participate) on a poll with one vote each! Youth Choice Award polls are open now until 9/27 8:00 pm Hawaiʻi time.

The contest is led by our Giant Pumpkin Contest Planning Team, which includes Josh Silva, Edible Crops Assistant Extension Agent; Kate Eickstead, Military 4-H Program Coordinator; Kalani Matsumura, Master Gardener Coordinator and Junior Extension Agent; Christine Hanakawa, Oʻahu 4-H Assistant Extension Agent; and Jhanella Gerardo, Hawaiʻi State FFA Officer and Waipahu High FFA Chapter.

Mahalo for everyone’s support. Now get out there and vote!
