While an appropriate feed intake is crucial for the reproductive performance of sows, there is a lack of recommendations currently for feed allowance of Guangdong Small-ear Spotted gilts during gestation. The effects of 2 different feeding patterns during gestation on the reproductive performance of Guangdong Small-ear Spotted gilts were investigated by assigning 80 gilts to 2 feeding pattern groups with a randomized complete block design in accordance with initial body weight and back fat thickness, followed by treatment with an incremental feeding pattern (IFP) and a concaved feeding pattern, respectively, with no difference in total feed intake. The IFP group showed a significant decrease in the stillbirth rate (P < 0.05) and an upward trend in piglet mean birth weight (P = 0.06). Furthermore, the IFP group exhibited an increase in the weights of stomach, supraspinatus tendon, triceps, and psoas minor in neonatal piglets (P < 0.05). Overall, the results of the present investigation showed that IFP could significantly reduce the stillbirth rate of Guangdong Small-ear Spotted gilts and increase the muscle weight of progeny.

虽然适当的采食量对母猪的繁殖性能至关重要，但目前对于广东小耳斑后备母猪妊娠期的饲喂量缺乏建议。通过根据初始体重和背部脂肪厚度将 80 头后备母猪随机分配到 2 个饲喂模式组中，研究 2 种不同饲喂模式对广东小耳斑小母猪繁殖性能的影响。分别采用增量饲喂模式（IFP）和凹饲模式进行处理，总采食量没有差异。IFP组死产率显着下降（P < 0.05），仔猪平均出生体重呈上升趋势（P = 0.06）。此外，IFP组新生仔猪的胃、冈上肌腱、肱三头肌和腰小肌的重量增加（P < 0.05）。总体而言，本调查结果表明，IFP可以显着降低广东小耳斑后备母猪的死产率，并增加后代的肌肉重量。
