GB20557—2006山羊冷冻精液

NY/T1450—2007中国荷斯坦牛生产性能测定技术规范

3术语和定义

本文件没有需要界定的术语和定义。

4外貌评分

4.1母羊外貌评分按附录A表A.1执行。

4.2公羊外貌评分按附录A表A.2规定执行。

4.3外貌评分等级标准按附录A.3规定执行。

5生长性能

5.1体重

用校正后的称重器于早饲前空腹称重，单位kg，精确到小数点后1位。不同年龄奶山羊体重范围

标准见附录B.1。

5.1.1初生重：羔羊出生后吃初乳前的活重。

5.1.2断奶重：羔羊断奶时（2～4月龄）的空腹活重，应记录准确的断奶日龄。

5.1.312月龄重：青年羊12月龄空腹重。

5.1.4成年体重：成年羊（24月龄）空腹重。

5.2体尺

不同年龄奶山羊体尺范围标准见附录B.1。

5.2.1体高：髻甲最高点到地面的垂直距离，用测杖测量。

DB43/T2330—2022

5.2.2体斜长：体斜长是指由肩胛前端至坐骨结节后端的直线距离，用软尺测量。

5.2.3胸围：胸围是指在肩胛骨后端，围绕胸部一周的长度，用软尺测量。

6繁殖性能

6.1种母羊

测定方法见附录C。

6.2种公羊

6.2.1精液品质

按GB20557的规定执行。

6.2.2后裔测定

见附录D。

7泌乳性能

7.1采样

按NY/T1450附录A的规定执行。

7.2产奶量

7.2.1个体实际产奶量

按NY/T1450的规定执行。

7.2.2个体校正300d产奶量

按附录E的规定执行。

7.2.3个体校正300d乳脂率4％标准奶量

按公式（1）计算：

FCMM(0.40.15F)…………（1）

式中：

FCM——个体校正300d乳脂率4％标准奶量；

F——实际乳脂率；

M——乳脂率为F的校正300d产奶量。
