Two experiments investigated the effects of lysophospholipid (LPL) supplementation on low-energy and low-nitrogenous diets for broilers. A total of 300 one-day-old male chicks (Ross 308) was allotted to 5 treatments in a completely randomized design. Each group consisted of 6 replicates with 10 birds each. Experimental diet I included positive control (PC) having 3,025 (starter), 3,150 (grower), and 3,200 kcal/kg (finisher) of ME; negative control (NC) was 150 kcal/kg of ME lower than PC, and LPL-05, LPL-10, and LPL-15 treatments were NC + 0.05%, 0.10%, and 0.15% of LPL supplementation, respectively. Experimental diet II included positive control (PC) having a formulated amount of crude protein including Lys and Met + Cys that met the Ross 308 standards; negative control (NC) was 4% lower CP and AA than PC; other treatments were supplemented with LPL at 0.05% (LPL-05), 0.10% (LPL-10), and 0.15% (LPL-15) into the NC, respectively. Experiment I showed that growth performance linearly increased as the LPL inclusion increased (P < 0.001). Broilers fed LPL-10 and LPL-15 increased digestibility of DM (P < 0.05), crude protein (P < 0.01), and total amino acids (P < 0.01) compared to NC. Serum glucose (P < 0.01) and high-density lipoprotein (P < 0.05) concentrations were greater in groups fed LPL-10 than those fed PC. Furthermore, leg muscle increased in birds fed LPL-10 compared with NC (P < 0.05). Experiment II observed a linear response to LPL supplementation in the whole period, in terms of body weight gain (P = 0.015) and feed conversion ratio (P = 0.027). Feeding of 0.15% LPL had promising effects on digestibility of crude protein and ether extract compared with NC (P < 0.01 and P < 0.05, respectively). Overall, LPL could be considered as a feed additive to reduced energy (-150 kcal/kg) or nitrogenous diets (-5%) in order to improve growth performance and nutrient digestibility without adverse effects on lymphoid organs and hepatic enzyme of broilers.

补充溶血磷脂以减少能量,粗蛋白和氨基酸饮食对肉鸡生长性能,营养消化率和血液状况的影响。

两项实验研究了溶血磷脂(LPL)补充对肉鸡低能量和低氮饮食的影响。完全随机设计将300只1天大的雄性小鸡(罗斯308)分配给5种处理方法。每组由6个重复样本组成,每组10羽。实验饮食I包括阳性对照(PC),其具有3,025(发酵剂),3,150(生长剂)和3,200 kcal / kg(精加工剂)的ME;阴性对照(NC)的ME比PC低150 kcal / kg,LPL-05,LPL-10和LPL-15的处理分别为NC +补充LPL的0.05%,0.10%和0.15%。实验饮食II包括阳性对照(PC),其具有一定量的粗蛋白,包括符合Ross 308标准的Lys和Met + Cys;阴性对照(NC)的CP和AA比PC低4%;其他治疗分别在NC中补充了0.05%(LPL-05),0.10%(LPL-10)和0.15%(LPL-15)的LPL。实验I表明,随着LPL夹杂物的增加,生长性能线性增加(P <0.001)。与NC相比,饲喂LPL-10和LPL-15的肉鸡增加了DM(P <0.05),粗蛋白(P <0.01)和总氨基酸(P <0.01)的消化率。LPL-10组的血清葡萄糖(P <0.01)和高密度脂蛋白(P <0.05)的浓度高于PC组。此外,与NC相比,饲喂LPL-10的家禽腿部肌肉增加(P <0.05)。实验二观察到整个时期对LPL补充的线性响应,以体重增加(P = 0.015)和饲料转化率(P = 0.027)表示。送入0。与NC相比,15%LPL对粗蛋白和乙醚提取物的消化率具有良好的影响(分别为P <0.01和P <0.05)。总体而言,LPL可被视为降低能量(-150 kcal / kg)或含氮饮食(-5%)的饲料添加剂,以改善生长性能和养分消化率,而不会对肉鸡的淋巴器官和肝酶产生不利影响。
