Experimental Protocol

46 adult multiparous Rasa Aragonesa ewes were housed in individual pens and offered a diet (once daily) that provided 1 x live weight maintenance requirements for 1 month prior to the beginning of the experimental procedures [12]. The estrus cycles were synchronized using intravaginal sponges, which were inserted for 14 days. At the time of sponge insertion, ewes were allocated to one of two planes of nutrition: a control (n= 21; 7.8 MJ of metabolisable energy per ewe), which continued to receive the same diet for 28 days, and a low plane of nutrition (n = 25; 3.9 MJ of metabolisable energy per ewe), which was offered at 50% of estimated daily requirements (pellet and straw) until the end of the experiment. At the time of sponge withdrawal, ewes were injected with 300 IU, i.v., equine chorionic gonadotropin (Intervet, Salamanca, Spain), and the occurrence of estrus (Day 0) was monitored every 8 h. Thirteen control ewes and 18 ewes in the low plane of nutrition were mated to vasectomized or intact rams to establish a cyclic and pregnant group, respectively, within each plane of nutrition
