Abstract

This study evaluated the effectiveness of different concentrations of arginine (Arg) in the diet on reproductive performance, body weight loss and plasma biochemical indices of breeding pigeons as well as on growth performance, carcass characteristics and plasma biochemical indices of squabs.2. In total, 360 pairs of 12-16-month-old European Mimas breeding pigeons were randomly divided into six groups (10 replicates of 6 pairs each). They were fed different pelleted diets with Arg levels of 0.58, 0.73, 0.88, 1.03%, 1.18 or 1.33%, respectively, for an experimental period of 45 d.3. The highest body weight gain during the incubation period occurred in the 1.03% Arg group. Feed intake increased curvilinearly throughout the trial in line with the increase in Arg levels, the highest being observed in the 1.18% Arg group.4. Body weight of squabs increased curvilinearly with an increase in Arg levels, with the highest occurring in the 1.18% Arg group. The FCR decreased curvilinearly with an increase in Arg levels. The lowest FCR occurred in the 1.03% and 1.18% Arg groups. Slaughter weights, eviscerated weight and pectoral muscle weights of 21 d squabs increased curvilinearly with increasing Arg levels and the best slaughter yield was observed in the 1.18% group.5. In addition, the highest plasma activities of total superoxide dismutase (T-SOD) and catalase (CAT) and the lowest malondialdehyde (MDA), aspartate transaminase (AST) and uric acid (UA) levels were observed in the 1.18% group. Using binary regression modelling in SPSS, the optimal dietary Arg level for breeding pigeons, based on the slaughter performance and FCR of squabs was 1.01-1.07%. Additionally, based on the full-term weight loss and oxidative stress of breeding pigeons as evaluation indexes, 0.96-1.01% Arg was optimal.6. In conclusion, the optimal dietary Arg for the best reproductive of breeding pigeons and growth performance of squabs in a 2+4 lactation pattern was 0.96%-1.07%.

摘要

本研究评估了日粮中不同浓度精氨酸（Arg）对种鸽繁殖性能、体重损失和血浆生化指标以及乳鸽生长性能、胴体特性和血浆生化指标的影响。
总共360对12 - 16月龄的欧洲肉鸽被随机分为六组（每组6对，共10个重复）。它们分别饲喂精氨酸水平为0.58%、0.73%、0.88%、1.03%、1.18%或1.33%的不同颗粒饲料，试验期为45天。
孵化期体重增加最多的是1.03%精氨酸组。整个试验期内采食量随精氨酸水平的升高呈曲线增加，在1.18%精氨酸组中观察到最高值。
乳鸽体重随精氨酸水平的升高呈曲线增加，在1.18%精氨酸组中最高。饲料转化率随精氨酸水平的升高呈曲线下降。最低的饲料转化率出现在1.03%和1.18%精氨酸组。21日龄乳鸽的屠宰体重、去内脏体重和胸肌重量随精氨酸水平的升高呈曲线增加，在1.18%组中观察到最佳屠宰率。
此外，在1.18%组中观察到总超氧化物歧化酶（T - SOD）和过氧化氢酶（CAT）的血浆活性最高，丙二醛（MDA）、天冬氨酸转氨酶（AST）和尿酸（UA）水平最低。使用SPSS中的二元回归模型，基于乳鸽的屠宰性能和饲料转化率，种鸽日粮中精氨酸的最佳水平为1.01 - 1.07%。此外，以种鸽的全期体重损失和氧化应激为评价指标，0.96 - 1.01%的精氨酸是最佳的。
总之，在2 + 4泌乳模式下，种鸽最佳繁殖性能和乳鸽最佳生长性能的日粮最佳精氨酸水平为0.96% - 1.07%。
