Abstract

This study was carried out to determine the dietary supplementation of organic zinc on feed intake (FI), feed conversion ratio (FCR), egg production (EP), egg mass (EM) and quality. A total of 120 ISA-Brown layers aged 20 weeks were used in this study. Hens were distributed randomly to four treatments (30 hens of each) with three replicates. The organic zinc was supplemented into basal diet at different concentrations as follows; (T1) 0, (T2) 100, (T3) 200, and (T4) 300 mg/kg. The results showed T2 was recorded improvement significant on FI, and FCR followed by T3. Also, egg mass in T2 was increased significantly compared with T1. The T2 and T3 were significantly higher in average egg production as compared to T1 which was showed the lowest value. There was no significant effect on egg quality when supplemented organic Zn to the diet of layer hens. It might be concluded that the dietary supple-mentation of 100 mg/kg of organic Zn has improved feed consumption which is reflected in the produc-tivity of laying hens.

基础饲粮中添加有机锌对蛋鸡生产性能的影响

本研究旨在测定日粮中添加有机锌对采食量（FI）、饲料转化率（FCR）、产蛋量（EP）、蛋质量（EM）和品质的影响。本研究共使用了120只20周龄的ISA Brown蛋鸡。母鸡被随机分配到四个处理（每个处理30只母鸡），三个重复。将有机锌以不同浓度补充到基础日粮中，如下所示；（T1）0、（T2）100、（T3）200和（T4）300 mg/kg。结果显示，T2对FI有显著改善，FCR其次是T3。此外，与T1相比，T2的卵子质量显著增加。T2和T3的平均卵子产量显著高于T1，T1显示出最低值。蛋鸡日粮中添加有机锌对蛋品质无显著影响。可以得出的结论是，日粮中添加100mg/kg有机锌可以提高蛋鸡的饲料消耗，这反映在蛋鸡的生产能力上。

期刊介绍： Journal of the Indonesian Tropical Animal Agriculture (JITAA) is a double blind peer-reviewed publication devoted to disseminate all information contributing to the understanding and development of animal agriculture in the tropics by publication of original research papers. The journal covers all aspect relating to Animal Agriculture, including: -Animal breeding and genetics -Animal feeding and nutrition -Animal reproduction -Animal biotechnology -Animal physiology -Animal production and technology -Animal products technology -Animal management and economics -Animal products processing and animal by-products -Animal microbiology -Livestock farming systems -Other related topics in relation to animal science. The topics of research are not only on Indonesian tropical animal agriculture, but also on other tropical regions of the world.
