The Effect of Dietary Energy and Protein Levels on Production in Breeding Female Ostriches.

1. In a study spanning two breeding seasons, we assessed the effect of different dietary energy and protein levels on body mass, body condition, and egg production of female ostriches. 2. During the first breeding season, groups were given diets with energy concentrations of 8.5, 9.5 and 10.5 MJ/kg dry mass (DM) metabolisable energy (ME) and protein concentrations of 135, 150 and 165 g/kg. In the second breeding season, groups were given diets with ME of 7.5, 8.5 and 9.5 MJ/kg and protein contents of 105, 120 and 135 g/kg. 3. Body mass of birds on diets of 7.5 and 8.5 MJ/kg ME decreased significantly in the course of the breeding season compared with birds fed on diets with higher energy contents and body measurements decreased, suggesting a loss of body condition. 4. Females fed on diets containing only 7.5 MJ/kg ME produced significantly fewer eggs at significantly longer intervals, resulting in fewer chicks hatched. 5. There was no significant difference in egg mass, initial chick mass, chick survival to one month of age and body mass of chicks at one month. 6. Dietary protein concentrations had no effect on egg production, egg mass, hatchability, initial chick mass, chick survival or chick mass at one month old. 7. The female ostriches regained their original body mass during the 4-month rest period between breeding seasons, but significant differences in some parameters during the second breeding season suggest that they may not have fully recovered their body condition. 8. A dietary energy content of 7.5 MJ/kg proved to have an adverse effect on egg production by breeding female ostriches, and it may be concluded from this study that a diet containing 8.5MJ ME/kg DM and 105 g/kg protein should be regarded as the minimum that can be used for breeding female ostriches without compromising egg production

The Effects of Personal Characteristics and Religious Orientations on Identification with All of Humanity and Humanitarian Behaviors

This research examined the effects of personal characteristics (empathy and authoritarianism) and religious orientations (Christian humanitarianism and religious fundamentalism) on identification with all humanity and resulting humanitarian behavior. This research also tested two hypothetical models (personality is primary, religion is primary) for the relationship between identification with all humanity and resulting humanitarian behavior. Two samples, consisting of 221 students and 158 adults, completed measures of authoritarianism, religious fundamentalism, dispositional empathy, Christian humanitarianism, identification with all humanity, and an assessment of humanitarian behaviors. As hypothesized, Christian humanitarianism and empathy were positively correlated with identification with all humanity and humanitarian behavior. Furthermore, authoritarianism and religious fundamentalism were negatively correlated with identification with all humanity and humanitarian behavior. Results also suggest that religious views may lead to the strengthening of specific personality characteristics and these, in turn, influence whether or not one identifies with all humanity and engages in humanitarian behaviors. Directions for future research are discussed as well as the implications of this research to real-world settings
