The goal of this research, conducted in the most southern part of Taiwan, was to create a new genotype: the "Hengchun Black Goat" (HB). Nubian (NU) goats were first crossed with a local breed, the Taiwan native (TN), then the F1 females were crossed with the imported black Boer (BO) bucks. The upgraded genotypes were then compared with the parental breeds and Kinmen (KM), another local breed, for growth traits and body conformation. The study concerned 1,136 kids born between 2005 and 2007. The analysed traits were body weight (BW), average daily gain and three linear measurements, namely height at withers, body length and chest girth. The results indicated that environmental factors, sex, birth and rearing type, dam parity and birth year had significant effects from birth to 6 months of age. The same differences persisted to 1 year. At 6 months of age, the least square means of BW were 16.2, 19.2, 25.1, 32.0, 23.9, 23.8, 23.0 and 23.9 kg, for KM, TN, NU, 1/2BO, 3/4BO, 7/8BO, BO and HB, respectively. These first results also indicate that the growth performances of the newly created line, Hengchun Black, were equivalent to those of Boer goats.
“恒春黑山羊”（HB）。努比亚（NU）山羊首先与当地品种台湾本土山羊（TN）杂交，然后F1代母羊再与引进的黑色波尔（BO）公羊杂交。之后将改良后的基因型与亲本品种以及另一个当地品种金门山羊（KM）在生长性状和体型方面进行比较。该研究涉及2005年至2007年间出生的1136只羔羊。所分析的性状包括体重（BW）、平均日增重以及三项线性测量指标，即肩高、体长和胸围。结果表明，环境因素、性别、出生和饲养类型、母羊胎次以及出生年份在出生至6月龄期间具有显著影响。这些差异一直持续到1岁。在6月龄时，KM、TN、NU、1/2BO、3/4BO、7/8BO、BO和HB的BW最小二乘均值分别为16.2、19.2、25.1、32.0、23.9、23.8、23.0和23.9千克。这些初步结果还表明，新培育的恒春黑山羊品系的生长性能与波尔山羊相当。
