I 摘 要 广西三黄鸡品种类型是目前两广地区饲养量最大的土鸡品种，为了解温氏培育的广西三黄鸡品种与社会优良品种的差异，特引进―参皇鸡‖品种开展该对比试验。本次试验对―参皇鸡‖和温氏广西三黄鸡父系N415、温氏广西三黄鸡配套（N415×N414）进行了生长速度、饲料转化率、体重均匀度、生活力、体尺指标、外观质量、屠宰性能等项目的测定、观察和评估。结果表明，参皇鸡体型紧凑、骨骼细致、外观质量好、但生长速度慢，从销售的角度来看，属于相对较高档次的土鸡类型。

1 前言 广西三黄鸡又叫信都鸡、糯垌鸡、大安鸡、麻垌鸡、江口鸡，分布于广西省桂东南部的桂平、平南、藤县、苍梧、贺县、岭溪、容县等地，为我国优良的地方品种，具有毛黄、脚黄、皮黄的特点，其早熟性好，肉质优良，体重适中，为广西地区传统养鸡生产的主要品种类型。改革开放后，从多的育种公司以广西三黄鸡为素材选育出不同特点的品种，该品种类型目前为两广地区饲养量最大的土鸡品种类型，估计年上市母鸡数量超过2亿只。 “参皇鸡”是广西“参皇”公司培育的广西黄品种，是在当地传统的优质地方品种（广西三黄鸡）基础上选育而成，该品种具有毛色淡黄、体型团圆、羽毛紧奏贴身、脚细等特点，在珠三角地区特别受欢迎，有较高的市场售价。N415和N414为温氏集团育种公司用广西三黄鸡为素材培育的广西三黄鸡品种的专门化品系，其中N415为父系，具有早熟、体重团圆、体重较大、毛色淡黄的特色；N414为母系，具有早熟、毛色纯黄、体重适中、产蛋量高的特点。 为比较温氏公司广西三黄鸡品种与社会优良品种的特点和差异，特引进不同来源的“参皇鸡”品种与育种公司的广西三黄鸡配套（N415*N414）、以及温氏广西三黄鸡父系系（N415）进行肉鸡性能对比试验，目的是分析温氏广西三黄鸡品种与社会优良品种的优劣，明确今后的改良方向。 2 材料与方法 2.1 试验材料 2010年6月3日，在育种公司肉鸡试验场第2栋、6栋进行试验鸡苗饲养，品种包括参皇1（种试）、参皇2（坝塘）、N415（蚕田）和N415×N414（良洞）的母苗。试验鸡苗每栏放240只左右，设有多组重复。 2.2 分组放置
