摘要
目的:研究农民对杂交品种(Malya x Sukuma)相对于本地 Sukuma 山羊的性能的看法。研究设计:研究采用横断面设计,并进行比较分析。研究地点和时间:研究在坦桑尼亚马斯瓦地区进行,为期三周。研究方法:有目的地从以前参与过杂交育种计划的家庭中抽取 50 名受访者。在调查过程中,他们就每种基因型的优点/积极和缺点/消极属性接受了问卷调查,然后根据市场价格、成熟体型和达到成熟体型的年龄对所需品种进行了排名。在对每户受访者进行访谈后,还对成熟的杂交山羊(Malya x Sukuma)和纯种 Sukuma 山羊进行了体重和体型测量。访谈数据使用 SPSS 的描述性统计选项进行分析,身体测量数据使用 SAS 的 GLM 程序进行分析。结果最受欢迎的品种是杂交山羊,因为其市场价格高、成熟体型大且成熟年龄早。苏库马山羊的优点是抗病(98%)和抗旱(94%),缺点是市场价格低(88%)、体型小(94%)和生长速度慢(72%)。杂交山羊的好属性是市场价格高(92%)、生长速度快(80%)和体型大(94%)。杂交山羊的不良属性出现频率很低。与苏库马山羊相比,杂交山羊体型较大。杂交山羊的成年体尺分别为体长(60.6±0.46 厘米)、心周(77.6±0.58 厘米)、肩高(66.4±0.42 厘米)和体重(35.1±0.52 千克),而苏库马山羊的成年体尺分别为 49.6±0.42 厘米、65.1±0.54 厘米、56.7±0.39 厘米和 21.6±0.48 千克。结论杂交山羊因其对家庭经济的有利影响而被农民接受。
Breed Preference by Farmers and the Morphometric Characteristics of Sukuma Goats and a Crossbred of Malya and Sukuma Goats in Maswa District, Tanzania
Aims: To study farmers’ perception toward performance of crossbreds (Malya x Sukuma) relative to the indigenous Sukuma goats.
Study Design: The study was of cross-sectional design employing comparative analysis.
Place and Duration of Study: The study was conducted in Maswa District of Tanzania over a three weeks period.
Methodology: Fifty respondents from household which were previously involved in the crossbreeding program were sampled purposively. In which they were interviewed using questionnaires on good/positive and bad/negative attributes for each genotype, then ranks of desired breed according to market price, mature body size and age of attaining mature size. Body weights and linear body measurement of mature crossbred (Malya x Sukuma) goats and pure Sukuma goats were also taken after interviewing each household respondent. Interview data were analyzed using descriptive statistics option of SPSS and body measurements were analyzed using GLM procedure of SAS.
Results: The most preferred breed was crossbred goats due to their high market price, large mature body size and early age of attaining mature size. Good attributes for Sukuma goats were disease resistance (98%) and drought resistance (94%) while bad attributes were low price in the market (88%), small body size (94%) and slow growth rate (72%). Good attributes for crossbred goats were premium price in the market (92%), high growth rate (80%) and large body size (94%). Bad attributes for crossbred goats had very low frequency. The crossbred goats were larger compared to Sukuma goats. Their mature body measurements were body length (60.6±0.46 cm), heart girth (77.6±0.58 cm), height at withers (66.4±0.42 cm) and body weight (35.1±0.52 kg) for crossbred goats while corresponding mature body measurements for Sukuma goats were 49.6±0.42 cm, 65.1±0.54 cm, 56.7±0.39 cm and 21.6±0.48 kg, respectively.
Conclusion: Crossbred goats were accepted by farmers due to their beneficial impact to the households’ economy.
