Nutrition and longevity in animals.

Calorie Restriction, Longevity and Cognitive Function

Companion Animals Symposium: Living beyond 20: Discoveries in geriatric companion animal biology.

It has traditionally been the responsibility of the animal science community to develop management, nutrition, health and well-being protocols for animals raised for production purposes. The vast array of scientific inquiry dedicated to production livestock have been instrumental in the management of these animals to optimize a value-based end product. Within the last several decades however, t...

Nutritional influence on epigenetics and effects on longevity.

PURPOSE OF REVIEW This review synthesizes recently published information regarding nutrition and its impact upon epigenetically mediated mechanisms involved in longevity and aging. RECENT FINDINGS Recent studies enriched considerably our understanding of the relationship between aging and gene-nutrient interactions that continuously shape our phenotype. Epigenetic mechanisms play an important...

New insights into cardiac aging.

All animals have limited life spans, and work in a variety of organisms has established that caloric restriction results in increased longevity. For example, inbred female mice fed an ad libitum diet had an average life span of 27 months, whereas calorie-restricted mice fed a diet with 65% fewer calories had an average life span of 45 months.1 The mechanisms by which caloric restriction retards...

Nutritional Effects of High Protein Feeds on Growth, Development, Performance and Overwintering of Honey Bee (Apis mellifera L.)

In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevi...
