Weaning is associated with a dramatic change in the nutritional status of young animals, and many neonates experience a lag in their normal trajectory of growth post-weaning because they have little experience of ingesting solid food. In the wild, animals are able to learn which foods are ‘safe’ through the mammary transfer of volatile flavours present in the maternal diet. This mechanism could be harnessed in a commercial environment by the use of flavour imprinting, a technique where a characteristic flavour is included both in the maternal and weanling's diet (for pilot data see Campbell, 1976). The use of this method could be associated with considerable increases in the profitability of animal production, however, the whole area is poorly understood. The objective of this experiment was to enhance our understanding of the effect of flavour imprinting on the acceptability of solid food, and hence our ability to predict the diet selection and food intake of newly weaned animals.

In The Wild

Playback experiments have proved to be a useful tool to investigate the extent to which wild animals understand numerical concepts and the factors that play into their decisions to respond to different numbers of vocalizing conspecifics. In particular, playback experiments have broadened our understanding of the cognitive abilities of historically understudied species that are challenging to test in the traditional laboratory, such as members of the Order Carnivora. Additionally, playback experiments allow us to assess the importance of numerical information versus other ecologically important variables when animals are making adaptive decisions in their natural habitats. Here, we begin by reviewing what we know about quantity discrimination in carnivores from studies conducted in captivity. We then review a series of playback experiments conducted with wild social carnivores, including African lions, spotted hyenas and wolves, which demonstrate that these animals can assess the number of conspecifics calling and respond based on numerical advantage. We discuss how the wild studies complement those conducted in captivity and allow us to gain insights into why wild animals may not always respond based solely on differences in quantity. We then consider the key roles that individual discrimination and cross-modal recognition play in the ability of animals to assess the number of conspecifics vocalizing nearby. Finally, we explore new directions for future research in this area, highlighting in particular the need for further work on the cognitive basis of numerical assessment skills and experimental paradigms that can be effective in both captive and wild settings.

Rats consuming a diet of 34% tallow select more protein and less carbohydrate than rats fed either 5% corn oil or tallow or 34% corn oil (25). To examine potential mechanism(s) of this phenomenon, we fed rats diets containing either tallow or corn oil at levels of 5 or 34% for 2 days. Sera were analyzed, and rats fed 34% tallow had higher serum insulin compared with those fed 34% corn oil. In a second experiment, rats were fed either 34% corn oil or tallow for 2 days. Brain tissues were analyzed, and rats fed 34% tallow had elevated serotonin in the raphe area compared with those fed 34% corn oil. In a third experiment, rats were fed either 34% corn oil or tallow for 2 days and then given dl-fenfluramine before diet selection. Fenfluramine depressed food intake to a greater degree in rats fed 34% tallow compared with those fed corn oil. These findings suggest that the diet selection behavior observed in tallow-fed rats may be mediated by a central serotonin system.

Background : Nutrition problems in toddlers become a public health problem when it exceeds WHO indicators in which the issue of malnutrition and undernutrition 17.8%, short toddlers 27.5% and thin toddlers 11.1%. The problem of undernutrition, short and thin toddlers are public health problem in the chronic category.Objective :  to determine the factor related to the nutritional status of toddlers in Loa Ipuh Health Centre. The design of this research is a cross-sectional study with total sample of 97 toddlers. Data collection uses anthropometric measurements, 24 hours of form food recall and questionnaires for mother's knowledge of breastfeeding complementary feeding and the utilization of health services.Method : Data analysis is using Pearson product-moment test with a significance level of 0.05. The results showed that there was a significant positive relationship between the food intake with the WAZ (P=0,000), HAZ (P=0,000) and  WHZ (P=0,021), mother's knowledge about complementary feeding with the WAZ (P=0,041), HAZ (P=0,010) and WHZ (P=0,010), utilization of health services with the WAZ (P=0,007), HAZ (P=0,009) and WHZ (P=0,006). Result : there is a significant positive relationship between intake of toddler feeding, mother's knowledge about complementary feeding and the utilization of health services with the nutritional status of toddlers WAZ, HAZ, and WHZ. Access to health services should be improved and evenly distributed throughout the health centre area.Conclusion : There is a significant positive relationship between food intake for children under five, maternal knowledge about complementary foods and health service utilization with the nutritional status

Background: Previous research state the correlation between vitamin D deficiency and Type 1 diabetes. The deficiency of Vitamin D is caused by vitamin D intake, sunlight exposure, or nutritional status. Indonesia, as a tropical country, is close to the equator and receives sunlight all year long. Little research has been done on vitamin D levels in children and adolescents with Type 1 Diabetes in Indonesia.Objective: The study aims to determine the relationship among sunlight exposure, nutritional status, food intake, and vitamin D levels in children and adolescents with Type 1 Diabetes.Methods: The study design was cross-sectional with a sample size of 31 children and adolescents aged 5-19 years. Sunlight exposure data were collected using the Sun Exposure Questionnaire form, nutritional status o BMI/age data were using the WHO Anthro, food intake data were using the Semi-Quantitative Food Frequency Questioner, and vitamin D level data were using the ELISA method. Statistical analysis was conducted by using SPSS Version 21 with Pearson and Spearman correlation test.Results: All respondents showed vitamin D deficiency. Most respondents had low sunlight exposure and nutritional status in the normoweight category. The majority of respondents had good energy and protein intake, excess fat, low carbohydrates, and low vitamin D and calcium.Conclusion:There is a positive relationship between sunlight exposure and vitamin D level (p = 0.001, r = 0.627). However, there is no relationship among nutritional status, protein intake, fat, carbohydrates, vitamin D and calcium on the level of vitamin D (p = 0.409; p = 0.240; p = 0.311; p = 0.822; p = 0.231; 0.382).

School Girls

This study aims to investigate the determinants of nutritional status (BMI) of school girls, selected randomly from the schools of Chittagong metropolitan area because good nutritional status is a prerequisite for good health, fertility and national productivity. The results of this study show that more than one-third (38.6%) school girls belong to underweight, 47.9% normal and 13.5% overweight. The overall mean BMI of the selected girls is found 20.03±4.06 kg/m2 with considerable variations by their background characteristics. The co-efficient of variation (20.27%) indicates that there exists extreme heterogeneity in BMI of the respondents. Co-efficient of skewness (β1=0.85) and excess of kurtosis (γ2=1.05) reflect that the distribution of BMI is positively skewed and leptokurtic. The mean BMI is found relatively high among the respondents living in the metropolitan area (21.18 kg/m2). The highest mean BMI is found among the girls belong to high family income group (21.62 kg/m2) and low (18.69 kg/m2) in lower family income group. Bivariate analysis indicates that religion, place of origin, place of residence, respondents’ education, arm circumference, fathers and mothers education and occupation, family income, family size, sibling size, skipping and cycling, duration of sporting activity and sleeping, and food intake are found to have significant association with nutritional status of the girls. The study also shows that BMI is significantly positively correlated with family income and negatively with duration of sporting activities. Multinomial logistic regression analysis illustrates that place of residence, arm circumference, mothers’ occupation, duration of sleeping and food intake is found significant predictors of BMI.
