This experiment was conducted to determine the optimal standardized ileal digestible lysine (SID Lys) level in diets fed to primiparous sows during gestation. A total of 150 (Landrace × Large White) crossbred gilts (weighing 149.9 ± 3.1 kg) were fed gestation diets (12.55 MJ of ME/kg) containing SID Lys levels of 0.43, 0.52, 0.60, 0.70 or 0.80% respectively. Gilts were fed 2.0 kg/day from day 1 to 80 and 3.0 kg/day from day 80 to 110 of gestation respectively. Gilts were allocated to treatments based on their body weight on the day of breeding. Weight gain from day 80 to 110 increased with increasing dietary SID Lys levels (p = 0.044). Fitted broken-line (p = 0.031) and quadratic plot (p = 0.047) analysis of body weight gain indicated that the optimal SID Lys level for primiparous sows was 0.70 and 0.69% respectively. During gestation, neither backfat thickness nor loin eye area was affected by dietary SID Lys level. Increasing dietary Lys had no effect on the litter size at birth or pigs born alive per litter. Litter weight at birth was not affected by dietary SID Lys level. The litter weight variation at birth quadratically decreased with increasing dietary SID Lys (p = 0.021) and was minimized at 0.70% dietary SID Lys. Gilts fed the 0.70% SID Lys diet had the highest dry matter (p = 0.031) and protein (p = 0.044) content in colostrum. On day 110 of gestation, gilts fed the 0.70% SID Lys diet tended to have the highest serum prolactin (p = 0.085) and serum insulin (p = 0.074) levels. The data demonstrate that the optimal dietary SID Lys was 0.70% for pregnant gilts, which is similar to the recommendation of 0.69% that was estimated by the NRC (2012).

“…In the present study, DT or ST of dietary threonine intake resulted in lower serum prolactin on day 110 of gestation. This observation is consistent with reports that pregnant sows consuming adequate lysine had higher serum prolactin concentrations compared with sows fed deficient lysine (Shi, Shi, Li, Li, & Wang, ; Zhang et al., ). In swine, lactogenesis is initiated by a prepartum peak of prolactin which is induced by a drop in progesterone concentration (Farmer, Robert, & Rushen, ).…”

“…The reproductive performance of sows can be significantly influenced by inadequate nutritional intake (Prunier & Quesnel, ). Formulation of the gestation diet for primiparous gilts should take into consideration sufficient nutrient supply for optimal foetal development, but also for the young sows to reach their mature body size (Zhang et al., ). Under commercial conditions, the sows are restricted fed during gestation to avoid extra body weight gain.…”

Dietary threonine imbalance is known to impair reproductive performances of gestating sows, but the underlying mechanisms are largely unknown. In this study, effects of deficiency and surplus dietary threonine during gestation on reproductive performance, serum metabolites and hormones concentration, and colostral nutrient and immunoglobulin contents of primiparous sows were investigated. Ninety primiparous pregnant gilts were assigned to one of the three dietary treatments with different standardized ileal digestible threonine/lysine ratios at 0.59, 0.72 and 0.85, which represented deficient (DT), adequate (AT) and surplus (ST) dietary threonine concentration respectively. Maternal body weight gain from day 80-110 of gestation was highest (p < .05) for gilts fed AT than for gilts fed DT or ST. On days 30 and 110, serum threonine concentration increases in a dose-dependent manner with the increasing of dietary threonine concentration in (p < .01), serum urea nitrogen concentration was lower (p < .01) in gilts fed AT than DT or ST, and serum insulin-like growth factor-I (IGF-I) was lowest (p < .05) for gilts fed DT. On day 110, gilts fed AT had lower serum progesterone concentration but higher concentrations of serum prolactin (p < .05) compared to DT and ST. Concentration of colostral immunoglobulin A and G from gilts fed DT was lower (p < .05) compared with gilts fed AT or ST. In conclusion, gilts with the adequate threonine intake were more able to conserve dietary amino acids to support foetal and maternal tissue gain. Deficient or ST threonine intake may induce a delay in changes in progesterone and prolactin concentrations during the prepartum period impeding the transition from pregnancy to lactation.

“…Teóricamente el aumento de las concentraciones de BHB después del parto, puede deberse a que la cerda pasa de un metabolismo anabólico de la gestación a un metabolismo catabólico en la lactancia, presentándose lipólisis de la grasa corporal de reserva para la producción de calostro y leche (15). Las cerdas en esta situación fisiológica están propensas a la acumulación de cuerpos cetónicos en el plasma, no obstante y posiblemente por el efecto de las dietas esto no fue observado.…”

RESUMENObjetivo. Evaluar el metabolismo lipídico de cerdas gestantes como respuesta a la modificación del nivel graso de la dieta y su efecto sobre la nutrición fetal a través de indicadores metabólicos. Materiales y métodos. Cincuenta y seis cerdas gestantes primíparas o multíparas se seleccionaron para suministrarles una dieta sin adición de grasa extra (SAp o SAm) o con adición de grasa extra (AGp o AGm). La dieta SA consistió en suministrar 3 kg/día de una dieta comercial convencional, en la dieta AG se redujo el maíz y se incluyó aceite de soya para proporcionar 20% de grasa extra. Las muestras sanguíneas se colectaron a los 85, 100, 113 días de gestación y a las 24 horas posparto, asimismo, al 50% de los lechones nacidos vivos de cada camada. Se analizaron concentraciones séricas de colesterol (CT), triglicéridos (TG), lipoproteínas de alta (HDL) y baja densidad (LDL), ácidos grasos no esterificados (NEFA) y betahidroxibutirato (BHB). Resultados. Las concentraciones séricas de HDL, LDL, CT, NEFA, BHB y TG, (p<0.01) aumentaron tanto en las cerdas primíparas como multíparas al día 100 y 113, pero disminuyeron a las 24 horas posparto. Los metabolitos sanguíneos en los lechones bajo la influencia de los dos tratamientos presentaron diferencias significativas (p<0.01). Conclusiones. No se encontró efecto de la modificación de la grasa en la dieta sobre LDL y NEFA; para los restantes indicadores se presentó diferencia en las cerdas en gestación. No se encontró correlación entre los indicadores metabólicos de las madres y los lechones. ABSTRACTObjective. Evaluate the lipidic metabolism of gestating sows in response to a modification in the fat level of the diet and its effect on fetal nutrition through metabolic indicators. Materials and methods. Fifty-six first-timers or multiparous sows were selected receive a diet without adding extra fat (SAp or SAm) or with extra fat addition (AGp o AGm). The SA diet consisted in feeding a conventional commercial diet of 3 kg/day, in the AG diet the corn was reduced and soybean oil was included to supply 20% extra fat. Blood samples were collected at 85, 100, 113 days of gestation and 24 hours postpartum, and on 50% of the piglets born alive per litter. Serum cholesterol (CT), triglycerides (TG), high (HDL) and low (LDL) density lipoproteins, non-esterified fatty acids (NEFA) and beta hydroxybutyrate (BHB) were analyzed. Results. The Serum concentrations of HDL, LDL, CT NEFA, BHB, and TG (p<0.01) increased in sows on days 100 and 113, but decreased at 24 hours postpartum. Blood metabolites in piglets under the influence of both treatments showed significant differences (p<0.01). Conclusions. There was no statistical effect from the modification of dietary fat on LDL and NEFA; for the remaining indicators differences were evident in pregnant sows. There was no correlation between metabolic indicators in mothers and piglets.
