Wheat germ oil was added to a larval liquid diet for rearing Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) to optimize fruit fly quality. Effects of various concentrations of wheat germ oil at 0.04, 0.07, 0.15, 0.30, and 0.66% and their possible mode of action were evaluated. Results suggest that addition of wheat germ oil does not affect pupal weight, larval developmental period, adult e...
The effect of residual yolk removal at hatch on growth and feeding behavior was assessed in lines of chickens divergently selected for low (LW) or high (HW) 56-day body weight. At hatch chicks were assigned to 1 treatment: removal of the residual yolk (R) or no surgery (I). Twenty-four chicks per line (12 I and 12 R) were assigned to an all-mash regimen (M) and 48 per line (24 I and 24 R) to a ...
Background and Objective: It is conceivable that caffeine consumption would induce gonadal changes. The aim of this study is to assess the impact of embryonic caffeine exposure on rat testis and prostate. Materials and Methods: Female rats were divided into (n=7): A control, only received drinking water. B and C groups received caffeine low dose (26 mg/kg) and high dose (45 mg/kg) respectively...
It is not rare that newly hatched chicks remain without feed for about 24 to 48 h before they are placed on farms due to a series of logistic operations. Furthermore, the spread in hatching time can also mount up to 30 to 48 h for late v. early hatchers. In other words, the practice is a complex combination of spread of hatch and delayed feed access. The present study was aimed to investigate t...
BACKGROUND Excessive maternal weight gain during pregnancy impacts on offspring health. This study focused on the timing of maternal gestational weight gain, using a porcine model with mothers of normal pre-pregnancy weight. METHODS Trial design ensured the trajectory of maternal gestational weight gain differed across treatments in early, mid and late gestation. Diet composition did not diff...
Caffeine was investigated for its possible fetal programming effects on reproductive function of male offspring. Sixty-five pregnant Wistar rats were grouped into four. Group 1 was control and received distilled water. Groups 2, 3 and 4 were treated orally with 1.14, 3.42 and 5.70 mg/kg body weight of caffeine respectively. Each group was subdivided into four based on gestation days (GD) 1-7, 8...
Introduction: In the present study the effect of chronic maternal high-fat diet consumption on energy homeostasis and glucose metabolism in response to chronic stress was investigated in adult male rats. Materials and Methods: Female rats were divided into two groups of normal and high fat diets. Each group received their diet from 3 weeks before pregnancy until the end of lactation. At 8 weeks...
Background: Prenatal bacterial lipopolysaccharides (LPS) exposure causes damage of the brain and gonadal system.The aim of this study included determination of astaxanthin effect to ameliorate undesired effects of bacterial LPS during fetal period and improve maternal behavior, body weight and length and neural changes in adult male NMRI mice. Methods: Pregnant female mice were divided into fou...
AIM To determine parental, especially paternal factors associated with the weight of the placenta and offspring. METHODS This population-based birth-cohort study includes 2947 singleton children born from April 2006 to 2007 and living in Drenthe, The Netherlands. Placental weight and birth weight were measured and questionnaires were filled out for this cohort. Associations between parental f...
