Resumen
To evaluate the effect of different feed restrictions on the fetoplacental development in rabbit does, a total of 32 animals were divided in three groups. Group C (n=9) was fed ad libitum throughout the pregnancy, whereas group P (n=11) was restricted to 50% of their requirements from day 0 to day 7 of pregnancy and group T (n=12) restricted to 50% throughout the pregnancy. On day 28 of pregnancy, fetuses from group T presented lower placental weight and fetal size respect group C and P (P<0.05). Feed restriction during the first week was related to a lower fetal distance from crown to tail basis respect group C. Does from group P consumed a higher amount of feed respect group C when the restriction period was concluded. In conclusion, a severe feed restriction throughout pregnancy affected negatively the development of the conceptuses, whereas the restriction during the first week reduced crown to tail basis respect group C. However, it was not linked to an altered ovulation or a higher implantational loss rate.
