The oxygen (O2) consumption, carbon dioxide (CO2) production, heat production (HP) and milk nutrient intake of 22 litters of suckling piglets were recorded every 4 days from the day after birth to weaning at 22 days of age. At weaning, 147 representative piglets of these litters were slaughtered to measure their chemical composition and to calculate the(More)
Data on energy metabolism and body composition changes of the pregnant and lactating sow have been considered in order to propose methods for determination of energy requirements according to a factorial approach. Daily requirements for maintenance at thermoneutrality amounts to about 105 and 110 kcal ME/kg BW.75 in pregnant and lactating sows,(More)
The effects of zearalenone on swine reproduction were investigated in two trials involving a total of 82 gilts which were allotted into three groups at puberty, mated at second estrus and slaughtered 80 d postbreeding. A control diet without mycotoxin (group 1) or an experimental diet containing 3.61 ppm (first trial) or 4.33 ppm zearalenone (second trial)(More)
BACKGROUND Sodium fluoride is the preferred agent to inhibit glycolysis. Its action is not immediate, however, and complete inhibition is delayed for up to 4 hours. A more effective method is needed. Acidification of blood combined with the addition of NaF and EDTA appears to be such a method. We studied whether acidification was indeed more effective than(More)
Using 73 Large White gilts, we studied the lysine requirement during lactation. Sow and pig performance and nitrogen balance of sows were measured during the total 21-d lactation period. Variation in body composition of sows between farrowing and weaning was determined by the comparative slaughter technique. Two levels of crude protein (15.5 and 17.1%) were(More)
The effects of growth hormone-releasing factor (GHRF) injections to sows during late gestation were investigated in two experiments. In the first one, four treatments were applied to eight catheterized sows according to two 4 x 4 Latin squares: oral administration of 2 mg of pyridostigmine, a cholinesterase inhibitor, per kilogram of BW (PYR group); i.m.(More)
This experiment was undertaken to determine whether pregnancy affects glucose metabolism and insulin sensitivity in sows fed at different levels. Four replicates of six multiparous Large White sows were involved. In each replicate, four sows were inseminated on the first postweaning estrus (pregnant group) and the two remaining were kept nonpregnant. Half(More)
Multiparous Large White sows were used in two experiments to determine the effects of energy intake on the reconstitution of body reserves during pregnancy. In Exp. 1, 21 sows received one of three different energy levels during pregnancy: 7.4, 8.8, or 10.4 Mcal DE/d. In Exp. 2, two energy levels (7.9 and 9.2 Mcal DE/d) were fed to 36 sows that mobilized(More)
This study was conducted to investigate the effects of feeding sows a bulky diet during gestation on their physiological and metabolic adaptations during the peripartum period, and to determine how these effects may relate to sow and piglet performances. From d 26 of gestation until farrowing, gilts were fed diets that contained 2.8 or 11.0% crude fiber(More)
