Effect of dietary energy intake during lactation on performance of primiparous sows and their litters.
A total of 146 primiparous sows was used in four replications of an experiment to investigate the effect of energy intake during a 28-d lactation on sow and litter performance. Dietary treatments consisted of three energy intakes; 10, 12 or 14 Mcal of metabolizable energy (ME) X sow-1 X d-1. All sows were fed equal amounts of crude protein, vitamins and minerals daily, which met or exceeded sta...
متن کاملBehavioral and physiological responses of primiparous sows to mixing with older, unfamiliar sows.
Pigs are mixed into new social groups at various stages of production, and this study investigated the response of gilts to mixing with older unfamiliar sows. Four groups of 6 gilts and 1 group of 5 gilts were housed in stable groups until the most recently bred female reached d 39 of gestation. Then, stable groups were split such that 15 gilts remained in their home pens (CON) and 14 gilts wer...
متن کاملEffects of postweaning dietary energy source on reproductive traits in primiparous sows.
An experiment was conducted to study the effects of major dietary energy source fed from weaning to ovulation or from ovulation to d 35 of pregnancy on reproductive traits in primiparous sows. Dietary energy sources were used to manipulate the plasma insulin concentration. One hundred thirteen sows were used in a split-plot design. From weaning to ovulation sows were fed at two times maintenanc...
متن کاملEffects of dietary valine:lysine ratios on lactation performance of primiparous sows nursing large litters
Eighteen sows were used to determine the effect of dietary valine:lysine (val:lys) ratios on lactation performance in primiparous sows and litter performance. Sows, raised in individual pens, were randomly assigned to 1 of 2 experimental diets containing different standardized ileal digestibility (SID) val:lys ratios of 0.80 or 0.85. Corn-soybeanwheat-based diets were formulated to achieve the ...
متن کاملExcessive gestational calorie intake in sows regulates early postnatal adipose tissue development in the offspring
Background: Many pregnancies in the United States are associated with maternal calorie overconsumption. Few data exist that track the impact of maternal and offspring calorie consumption on the risks for obesity development. Methods: To determine the effects of maternal calorie intake during gestation on programming for adiposity in the offspring, pregnant gilts were fed either a normal (NE) or...
