Abstract

Four hundred and eighty, 53 weeks old Isa Brown layers were used for the 8 weeks feeding trial to determine the internal and external egg qualities of layers fed two proprietary feeds (designated Top feed (TF) and Animal Care feed (AC)) in five dynamics and two feeding frequencies. The birds were randomly allocated in a 5 x 2 factorial arrangement to five feeding dynamics (D1 TF only; D2 AC feed only; D3 weekly alternation of TF & AC; D4 Alternation of TF & AC every two weeks; D5 Monthly alternation of TF & AC) and two feeding frequencies (Twice & Thrice daily). Data were collected on external and internal egg qualities and analyzed using Analysis of variance (ANOVA). The results showed that both feeding dynamics and feeding frequencies significantly (p<0.05, R2=0.4) contributed to egg length as single factor. However, egg shape index (p=0.002), % yolk (0.00), yolk weight (p=0.004), egg moisture (0.003), egg fat (0.001) and egg carbohydrate (0.001) were influenced by interaction effect of feeding dynamics and feeding frequency. From the findings of this study, alternating brands of feed in the short term (weekly) and feeding laying birds twice daily is recommended.

两种专有饲料对蛋鸡内外蛋品质的影响

选用480只53周龄的伊沙布朗蛋鸡进行8周的饲粮试验，研究在5种动力和2种饲喂频率下饲喂两种专有饲料(顶级饲料(TF)和动物护理饲料(AC))的蛋鸡的内外蛋品质。按5 × 2的阶乘随机分配到5个摄食动态组(D1 - TF;D2只交流馈电;D3每周TF和AC交替;D4每两周换气;D5每月交替饲喂TF和AC，两次饲喂频率(每日2次和3次)。收集卵外品质和卵内品质数据，采用方差分析(ANOVA)进行分析。结果表明:采食动态和采食频率对卵长均有显著影响(p<0.05, R2=0.4)。而蛋形指数(p=0.002)、蛋黄百分比(0.00)、蛋黄重(p=0.004)、鸡蛋水分(0.003)、鸡蛋脂肪(0.001)和鸡蛋碳水化合物(0.001)受饲喂动态和饲喂频率的交互作用影响。根据本研究的结果，建议在短期内(每周)交替饲喂品牌，每天饲喂两次。
