摘要
为研究鲁西黑头羊新品种种质特性及开发利用,对鲁西黑头羊中心产区自然生态条件、品种特性、体型外貌、生产性能、杂交改良等进行了调查研究、对比试验和统计分析。研究结果表明,鲁西黑头羊外貌特征一致,生长速度快、产肉性能好、繁殖力强,适应性广。成年公羊体重(107.33±5.43)kg,成年母羊体重(60.10±4.52)kg,屠宰率(56.63±1.88)%,产羔率192.14%~222.12%。鲁西黑头羊完全具备专门化肉羊品种的优点,既可纯繁生产优质肥羔,也可做父本对低产品种进行杂交改良,推广应用前景广阔。该研究可为该品种的进一步选育提高及杂交利用提供理论依据。
In order to study the germplasm characteristics and development utilization of new varieties of Luxi black headed sheep,a survey,comparative experiment,and statistical analysis were conducted on the natural ecological conditions,variety characteristics,body shape and appearance,and production performance indicators in the central production area of Luxi black headed sheep.The results showed that Luxi black headed sheep had the same appearance characteristics,fast growth,good meat production,strong Fecundity and wide adaptability.Adult ram weighs(107.33±5.43)kg;The ewe weighs(60.10±4.52)kg,with a slaughter rate of(56.63±1.88)%and a lambing rate of 192.14%to 222.12%.Luxi Black Head Sheep fully possesses the advantages of specialized meat sheep breeds,which can produce high-quality fat lambs through pure breeding,and can also be used as a male parent for hybrid improvement of low yield varieties.The prospects for promotion and application are broad.This study can provide theoretical basis for further breeding,improvement,and hybrid utilization of this variety.
