The objective of this study was to investigate whether valine (Val) supplementation in a reduced protein (RP) diet regulates growth performance associated with the changes in plasma amino acids (AAs) profile, metabolism, endocrine, and neural system in piglets. Piglets or piglets with a catheter in the precaval vein were randomly assigned to two treatments, including two RP diets with standardized ileal digestible (SID) Val:Lysine (Lys) ratio of 0.45 and 0.65, respectively. The results indicated that piglets in the higher Val:Lys ratio treatment had higher average daily feed intake (ADFI) (P < 0.001), average daily gain (ADG) (P = 0.001), feed conversion ratio (FCR) (P = 0.004), lower plasma urea nitrogen (P = 0.032), expression of gastric cholecystokinin (CCK), and hypothalamic pro-opiomelanocortin (POMC). Plasma AAs profiles including postprandial plasma essential AAs (EAAs) profile and in serum, muscle, and liver involved in metabolism of AAs and fatty acids were significantly different between two treatments. In conclusion, Val influenced growth performance associated with metabolism of AAs and fatty acids and both endocrine and neural system in piglets.

减少蛋白质饮食中的缬氨酸补充可部分通过调节仔猪血浆氨基酸谱，代谢反应，内分泌和神经因子来调节生长性能
这项研究的目的是研究在减少蛋白（RP）饮食中补充缬氨酸（Val）是否能调节与仔猪血浆氨基酸（AAs）分布，代谢，内分泌和神经系统变化相关的生长性能。仔猪或在前腔静脉中带导管的仔猪被随机分配到两种治疗方法中，包括两种回肠日粮，其回肠消化率（SID）Val：赖氨酸（Lys）的标准比分别为0.45和0.65。结果表明，采用较高的Val：Lys比处理的仔猪平均日采食量（ADFI）（P <0.001），日平均增重（ADG）（P = 0.001）和饲料转化率（FCR）（P = 0.004 ）较高。），血浆尿素氮较低（P= 0.032），胃胆囊收缩素（CCK）和下丘脑前视紫红质皮质激素（POMC）的表达。两种治疗之间的血浆AA谱（包括餐后血浆必需AAs（EAA）谱）以及参与AA和脂肪酸代谢的血清，肌肉和肝脏中的血浆AA谱显着不同。总之，Val影响仔猪的AA和脂肪酸代谢以及内分泌和神经系统代谢相关的生长性能。
