Effects were compared of two methods of feed restriction (skip-a-day, SAD, vs. skip-two-days, STD) during 4 to 22 wk of age on the development, uniformity, and subsequent performance of White Rock pullets. The pullets, housed in cages, consumed the same amount of feed in both treatments. Nevertheless, body weights of birds kept under the STD feeding regimen were significantly (P less than .01) lower. This difference was still significant (P less than .05) at 35 wk of age. Flock uniformity at 11 wk of age was significantly (P less than .05) higher in pullets kept on the STD feeding program. Plasma glucose and corticosterone levels in fasted pullets and corticosterone levels in fed birds at the age of 21 wk were not affected by feeding regimen. However, the increase in plasma glucose after feeding was significantly (P less than .05) higher in pullets on the STD feeding program. Plasma corticosterone levels were consistently, and at times significantly (P less than .05), higher in fasted birds. Laying of the first egg was significantly (P less than .05) delayed in hens previously kept on the STD feeding regimen. Rate of egg production and egg weights up to 35 wk of age were not affected by the method of feed restriction.
比较了两种限饲方法（隔日限饲，SAD，与隔两日限饲，STD）对4至22周龄白洛克小母鸡发育、均匀度及后续生产性能的影响。小母鸡饲养在笼中，两种处理方式下的采食量相同。然而，采用STD饲喂方案饲养的鸡体重显著更低（P<0.01）。在35周龄时，这种差异仍然显著（P<0.05）。采用STD饲喂方案饲养的小母鸡在11周龄时的鸡群均匀度显著更高（P<0.05）。21周龄时，禁食小母鸡的血浆葡萄糖和皮质酮水平以及采食母鸡的皮质酮水平不受饲喂方案影响。然而，采用STD饲喂方案的小母鸡采食后血浆葡萄糖的升高显著更高（P<0.05）。禁食鸡的血浆皮质酮水平始终较高，有时显著更高（P<0.05）。先前采用STD饲喂方案饲养的母鸡首次产蛋显著延迟（P<0.05）。至35周龄时的产蛋率和蛋重不受限饲方法的影响。
