“…In the last 2 decades, the breeding of rabbits moved on from traditional production systems to more intensive ones using modern prolific lines (see review of Castellini et al, 2010). Consequently, the productivity of rabbit farms has increased but, at the same time, several problems related to the health status and the welfare of does also have appeared, for example excessive replacement rates, high mortality and culling rates and hypo-fertility (Rosell and de la Fuente, 2009;Sánchez et al, 2012).…”

“…In modern intensive rabbit breeding, the reproductive management of the rabbit doe, the genetic programmes and the feeding systems have greatly increased the profitability of the system but, at the same time, several problems related to the health status and the welfare of does have also appeared, as reviewed by Pascual et al (2006 and and Castellini et al (2010). One of these concerns the difficulties of the does during the peripartum.…”

“…In this period the doe is exposed to dramatic physiological and dietary challenges, including the abrupt transition from pregnancy to lactation that could be exacerbated if the number of foetuses in gestation is very high. The manner in which these changes occur and how they are managed are of great importance as they are closely linked with lactation success, the incidence of clinical and subclinical postpartum diseases and reproductive performance for the next gestation, all factors that affect significantly the profitability of the system (Castellini et al, 2010).…”

“…The genetic selection programs for reproductive traits have mainly focused on improving litter size , and the breeding of rabbits moved on from traditional production systems to more intensive ones using modern, prolific lines (Castellini et al, 2010). The high number of foetuses of these breeds may trigger the pregnant does to respond to metabolic challenges happening in the last week of pregnancy.…”

The aim of this study was to investigate the metabolic and biochemical changes in plasma that occur in the reproductive rabbit doe close to the parturition, as well as if the number of offspring affects the metabolism and the health status of the doe. At − 3, 4 and 12 days from parturition (-D3, D4, and D12, respectively) nine rabbit does at their third parity from a commercial hybrid line (HYPLUS PS 19) selected for high prolificacy were weighted and blood was collected for a wide inflammometabolic profile. According to the number of offspring the does were retrospectively divided in two groups: high litter size group (HI; n = 5) and low litter size group (LO; n = 4). BW was higher (P < 0.01) at -D3 and had the lowest values at D4. At D12, the BW was lower (P < 0.05) in LO compared with HI. Several metabolites significantly changed from dry to lactation period. Glucose and cholesterol had the lowest levels at -D3; non-esterified fatty acid (NEFA) and aspartate aminotransferase had the highest values before parturition (P < 0.05); creatinine and β-hydroxybutyrate (BHBA) were higher at -D3 with respect to D4 (P < 0.05). The lowest value of paraoxonase was observed in does at -D3 (P < 0.05), whereas at this time ceruloplasmin and total bilirubin had the highest concentration (P < 0.05). The differences for blood profile parameters between does grouped according to litter size were mainly evident before parturition (-D3). In particular, BHBA, NEFA and total bilirubin had higher concentrations (P < 0.05) in HI v. LO group, whereas albumin and PON were lower in HI group (P < 0.01). After parturition there were no significant differences for the metabolic parameters between the two groups. The results show that for reproductive rabbit doe the last days of gestation are very stressful from a metabolic and inflammatory point of view. The genetic selection of does for higher litter size has increased their ability to mobilize body reserves in order to guarantee the nutrients to a high number of kits. This exposes them to a more severe metabolic and inflammatory challenge during the transition period. Consequently, feeding and managerial strategies for high prolificacy periparturient rabbit does should be revised.

“…En consecuencia, la gestación subsecuente que diera lugar al evento de superfetación pudo ocurrir gracias a dos circunstancias facilitadoras: la primera, consistente con una condición folicular pre-ovulatoria concomitante con mayores concentraciones de estradiol en plasma, cuyos niveles se elevan de manera espontánea en la coneja durante los días 1, 5, 7, 23 y 30 posparto [30,31], y con respecto a la segunda, que dicha variación hormonal desencadenó la circunstancia ideal para que se presentara la indispensable receptividad sexual que permitiera que se concretara el apareamiento, hecho apoyado por informes que señalan a la coneja como un ovulador inducido capaz de sostener el desarrollo folicular durante ciertas etapas del embarazo [16,30,31,32].…”

Reportes de casoPosible superfetación en una coneja raza nzb (Oryctolagus cuniculus) concomitante a retraso del desarrollo intrauterino (rdiu) resumen. Los trastornos reproductivos del conejo son complejos y numerosos incluyendo rarezas como la superfetación (sf). Se describe un posible caso de sf descubierto accidentalmente, asociado a distocia en una coneja de la raza nzb, que sufre de severa hemorragia vaginal, postración, hipotermia y no reactiva al estímulo. Durante la palpación, numerosos fetos fueron detectados en ambos cuernos uterinos sin respuesta a la manipulación obstétrica para extracción. La cesárea urgente reveló seis productos a término; uno de talla superior muerto en posición caudal bloqueando el canal de parto cerca del cuello uterino, y uno más subdesarrollado retirado del cuerno uterino derecho entre una camada de siete gazapos. La madre se eutanizó in extremis mediante sobredosis de Pentotal Sódico. Morfológicamente, los fetos a término registraron pesos de 65,8, 70,7, 61,3, 68,4, 53,7 y 65,3 gramos, respectivamente; el crío subdesarrollado pesó 19,5 gramos y presentó meconio abundante ausente en el resto. Las longitudes corporales totales (lct) realizadas análogamente bajo criterio céfalo-caudal (cc), reportaron 10,7,11,2,9,9,10,9,8,6 y 9,2 cm, respectivamente, y sólo 3,9 cm para el crío subdesarrollado, sin evidencia de malformaciones o infección. Basado en observaciones clínico-quirúrgicas el diagnóstico primario fue de distocia obstructiva, asociada a un sobredesarrollo fetal e inercia uterina secundaria. La comparación morfológica del crío subdesarrollado se postuló como superfetación concomitante a gestación/distocia, sin datos de muerte fetal o maceración. Los registros apuntan que estando gestante esta hembra fue re-apareada. Sin embargo, no está claro cómo la coneja experimentó una segunda implantación y notable retraso en la maduración de un solo feto.EduardoPalabras clave: coneja, distocia materna, maduración interrumpida, reproducción, superfetación.
