DIETARY REQUIREMENTS FOR REPRODUCTION

Evaluation of Dietary Calcium Requirements in Fayoumi Laying Hens

The experiment was carried out in poultry experimental station belonging to NRC, Cairo, Egypt. A total of 120 Fayoumi layers, 45 weeks old, were randomly divided into four equal groups. Each group included three replicates (10 hens in each). The first group was fed the control diet containing 3.3% gram Ca, whereas, the other three received diets containing 2.8, 2.6 and 2.4% gram Ca, respectivel...

Nutritional requirements and actual dietary intake of adult burn patients

Background: Nutritional support of the burn patient is essential to optimize, host immune defenses and to promote prompt wound healing. Furthermore, the increased needs in calorie requirement of burned patients, the composition of proteins, carbohydrates and fats in their diet is important. The purpose of this study was to evaluate energy, macronutrient and micronutrient intake and comparing wi...

Appetite for reproduction: dietary restriction, aging and the mammalian gonad

The major physiologic theory of aging, the disposable soma theory, links dietary restriction (DR), also known as calorie or food restriction, to prolonged lifespan and makes specific predictions about the effects of aging and DR on reproduction. A recent study in BMC Biology profiling the effects of aging and DR on gonadal gene expression provides novel molecular evidence that has a significant...

Some thoughts on dietary requirements of macro-elements for ruminants.

Dietary protein for athletes: from requirements to optimum adaptation.

Opinion on the role of protein in promoting athletic performance is divided along the lines of how much aerobic-based versus resistance-based activity the athlete undertakes. Athletes seeking to gain muscle mass and strength are likely to consume higher amounts of dietary protein than their endurance-trained counterparts. The main belief behind the large quantities of dietary protein consumptio...
