摘要：

【目的】比较不同血统比例特克赛尔羊与哈萨克羊杂交组合后代羔羊的早期生长发育规律,筛选早期生长快、增重显著的杂交组合,为培育哈萨克羊肉用新类型提供理论依据。【方法】测量4个不同杂交组合(即特克赛尔羊×F₁、F₂×F₁、F₂×哈萨克羊、F₁×F₂),共计1 193只单胎型羔羊出生至180日龄期间不同生长阶段的体重,比较4个不同杂交组合的累积生长、绝对生长、相对生长等生长性状,并利用Logistic、Gompertz、Von Bertalanffy非线性拟合模型拟合与分析体重数据生长曲线,筛选出早期生长性能最佳的杂交组合。【结果】羔羊从出生至180日龄生长过程中,F₂×F₁杂交组合羔羊生长速度快,生长强度大,增重较显著,拐点体重较高的同时也能最快到达拐点体重。其次是特克赛尔×F₁、F₂×哈萨克羊杂交组合羔羊。F₁×F₂杂交羔羊生长发育速度较迟缓,生长强度较低,体重显著低于同一日龄的其它杂交组合。尽管F₁×F₂杂交组合公羔拐点体重高,但到达这一体重所需时间也过长。【结论】哈萨克羊早期生长发育性能最佳的杂交组合是F₂×F₁。

Abstract:

【Objective】 Through the comparison of the early growth and development law of the offspring of different generations of hybrid combinations of Texel Sheep and Kazak sheep, this project aims to screen the hybrid combinations with fast growth and significant weight gain in the early stage, and to determine the optimal cross fixation mode, so as to provide a theoretical basis for screening new types of meat breeding of Kazak sheep.【Methods】 Based on the previous studies of Kazak sheep, the body weight of four different hybrid combinations (Texel Sheep× F₁, F₂ × F₁, F₂ × Kazakh sheep, F₁ × F₂), a total of 1,193 singleton lambs from birth to 180 days of age was measured and their cumulative growth, absolute growth and relative growth were fit and compared by using Logistic, Gompertz and Von Bertalanffy nonlinear fitting models, from which, the crosses with the best early growth performance were selected and the optimal regression equation established and the growth curve drawn.【Results】 From birth to 180 days of age in lambs of different hybrid combinations, F₂ × F₁ hybrid lambs have fast growth speed, high growth intensity, significant weight gain, and can reach the inflection point weight faster when the inflection point weight is higher.Texel×F₁, F₂×Kazakh Hybrid lambs followed.In contrast, F₁×F₂ hybrid lambs have slower growth and development speed, lower growth intensity, and the body weight is significantly lower than other hybrid combinations of the same age.Although the male lambs has a high inflection point body weight, it takes too long to reach this body weight.【Conclusion】 Through screening, it is considered that the hybridized combination with the best early growth and development performance is F₂ × F₁.
