dc.description.abstract | Se evaluó el efecto del peso al destete (PD) (4,0±0,7 kg y 6,3±0,6 kg), temperatura ambiental (TA)(29±1,7oC y 25±1,3oC), y nivel de energía metabolizable del pienso (EMP) (3250, 3400, 3550 o 3700kcal EM/kg) sobre el desempeño, digestibilidad de los nutrientes, metabolizabilidad de la energía bruta(MEB) y retención de nitrógeno (CRN), en lechones destetados. De 1 a 14 días post destete (pd), fueronutilizados 64 lechones de linaje comercial, en una jaula/dupla metabólica. De 15 a 28 días pd, perma-necieron 32 animales. En el período total, la conversión alimenticia (CA) presentó interacción entre PDy EMP resultando en mejor CA en lechones pesados en respuesta al incremento de EMP. Lechones levespresentaron mayor CA y menor ganancia de peso (GP) y consumo de pienso (CP). La TA 25 oC propicióuna mejor GP y mayor CP. Los niveles de energía no fueron significativos para ninguna de las respu-estas de desempeño evaluadas. Para el período total se presentó un aumento lineal de la digestibilidadaparente de la materia seca, proteína bruta, energía bruta, grasa bruta, del CRN y de la MEB en respu-esta al incremento de la EMP. En TA 25oC todos los parámetros de metabolismo evaluados fueronmenores que en TA 29oC. No hubo efecto del PD en el estudio de metabolismo. | es |
dc.description.abstract | This research was developed to evaluate the effect of weaning weight (WW) (4.0±0.7 kg and 6.3±0.6kg), environmental temperature (ET) (29±1.74oC and 25±1.3oC) and dietary ME level (DME) (3250,3400, 3550 or 3700 kcal of ME/kg) on performance, digestibility of nutrients, gross energy metabolizabi-lity (GEM) and nitrogen retention (NR) for newly–weaned piglets. In the period, from 1 to14 days afterweaning, sixty four hybrid piglets were allotted on metabolic cages (two animals/cage) and in the periodfrom 15 to 28 days after weaning, 32 piglets were kept individually housed in the same cage. In the totalperiod, there was a significant interaction between WW and DME for feed: gain ratio (FGR) with theheavy piglets presenting better FGR in response to increase of DME. Piglets with lower weight had higherfeed: gain ratio and weight gain and feed intake reduced. Piglets allotted in environment with 25oC sho-wed greater WG and FI. There was no effect of DME on performance evaluated. In the total period,apparent digestibility of dry matter, crude protein, gross energy and crude fat, NR and GEM showedlinear effect by increased of DME. In all metabolic parameters, the animals kept at 25oC of ET had lowervalues than the animals kept at 29oC. WW had no influence on metabolism of nutrients. | en |
