The effect of low-density broiler breeder diets on performance and immune status of their offspring.
Effects of low-density broiler breeder diets on offspring performance and mortality were studied using 2,100 female and 210 male Cobb 500 breeders. Breeder treatments involved 4 experimental groups and a control group with normal density diets (ND, 2,600 kcal of AME/kg during rearing and 2,800 kcal of AME/kg during laying). In treatment 2, nutrient densities were decreased by 12% (LD12) and 11%...

متن کاملEffects of maternal nutrition on conceptus growth and offspring performance: implications for beef cattle production.
Developmental programming is the concept that a maternal stimulus or insult at a critical period in fetal development has long-term effects on the offspring. Historically, considerable effort has been made to understand how nutrition influences health and productivity during the postnatal period. Whereas maternal nutrition during pregnancy plays an essential role in proper fetal and placental d...
متن کاملAltering ewe nutrition in late gestation: II. The impact on fetal development and offspring performance.
The present study was conducted to evaluate the effects of offering Belclare X ewes a single diet rationed to 80, 100, or 120% of recommended ME requirements from d 119 of gestation to parturition, with concurrent changes in other dietary nutrients.

متن کاملNutrition and mental performance.
There is no doubt that nutritional status can have significant and sometimes profound effects on human mental performance (Table 1). This is evidenced by, for example, the consequences of chronic and severe food restriction (Smart, 1993), thiamin deficiency (Kanarek & Marks-Kaufman, 1991), and Fe deficiency (Pollitt, 1987). Acute effects of food and fluid ingestion have also been described, and...
