This study examined critical periods in development to determine when offspring were most susceptible to dietary sodium manipulation leading to amphetamine sensitization. Wistar dams (n = 6-8/group) were fed chow containing low (0.12% NaCl; LN), normal (1% NaCl; NN), or high sodium (4% NaCl; HN) during the prenatal or early postnatal period (birth to 5 wk). Offspring were fed normal chow therea...

hatch as a % of initial egg weight demonstrated an interaction of storage treatment and rate of warm up. This difference appears to be the result of the significant differences in the low amount of residual yolk at hatch in the slow fresh chicks. The slow had significantly elevated heart rates. Relative heart weight was significantly greater for fresh versus stored and slow versus fast warm up ...

Background—We sought to examine the association of gestational weight gain (GWG) and prepregnancy weight with offspring adiposity and cardiovascular risk factors. Methods and Results—Data from 5154 (for adiposity and blood pressure) and 3457 (for blood assays) mother-offspring pairs from a UK prospective pregnancy cohort were used. Random-effects multilevel models were used to assess incrementa...

Submitted: Jan 2, 2013; Accepted: Feb 6, 2013; Published: Aug 18, 2013 Abstract: This study was undertaken to determine the effects of divergent selection and different positions of Japanese quail eggs in artificial incubation on hatchability, egg weight loss, chick weight. 300 Japanese quail (100 birds in each line) were used for egg collection. These lines have been selected for high (HW) and...

body weight (bw) is a complex and important economic trait that may benefit from the implementation of marker assisted selection (mas). the objective followed in this study was to identify qtls associated with bw at different ages as distinct traits based on an experimental half-sib cross of japanese quails divergently selected for bw at 4 weeks of age. the body weights at hatch, and as well at...

BACKGROUND As egg production and offspring care are costly, females should invest resources adaptively into their eggs to optimize current offspring quality and their own lifetime reproductive success. Parasite infections can influence maternal investment decisions due to their multiple negative physiological effects. The act of preening--applying oils with anti-microbial properties to feathers...

Poor early growth is associated with Type II diabetes, hypertension and other features of the metabolic syndrome in adulthood. It has been suggested that this results from the development of a thrifty phenotype by a malnourished fetus. Such a phenotype would predispose the offspring to the development of obesity if born into conditions of over-nutrition. The present study aimed to determine if ...

BACKGROUND Maternal obesity and hyperglycemia increase risk of obesity and diabetes in offspring later in life. OBJECTIVE We examined the relation between gestational glycemia and prepregnancy body mass index (ppBMI) with offspring growth in an Asian mother-offspring cohort. DESIGN Pregnant mothers undertook a 75-g 2-h oral-glucose-tolerance test at 26-28 wk of gestation. In 937 singleton o...

BACKGROUND Few studies have examined the relations of adiposity and lifestyle factors in young offspring with their parents as children (parentschild) or at their current age (parentsadult). Therefore, we compared measures of adiposity and lifestyle in parentschild and parentsadult with their offspring. METHODS Two generations (one parent and his/her offspring) participated in this study: 234...
