Abstract Maternal undernutrition during pregnancy impairs offspring behaviours and thereby their survival rate indirectly by decreasing lamb birth weight or by deteriorating milk production which in turn limits bonding of the dam with the neonate. This study was aimed to investigate the effect of maternal feed restriction during late pregnancy on performance and behaviours of ewes and their lambs. Twenty-four Ghezel ewes were allocated to the three experimental treatments including ad libitum intake (AL); restricted feed intake by 60 % (FR); and propylene glycol- supplemented restricted diet (FR + PG). AL and FR + PG ewes had higher circulating oestradiol (P

妊娠晚期饲料限制和生糖前体对 Ghezel 母羊及其后代行为和性能的影响

摘要 母体在怀孕期间营养不良会通过降低羔羊出生体重或降低产奶量从而限制母体与新生儿的结合间接损害后代行为，从而间接损害其存活率。本研究旨在调查母羊在妊娠后期限制饲料对母羊及其羔羊的生产性能和行为的影响。24 只 Ghezel 母羊被分配到三种实验处理中，包括随意摄入 (AL)；将饲料摄入量限制为 60 % (FR)；和丙二醇补充限制饮食（FR + PG）。AL 和 FR + PG 母羊具有更高的循环雌二醇（P
