Data on 75 567 ejaculates from 1 417 boars of the breeds Czech Large White and Czech Landrace collected in 23 AI centres between 2000 and 2007 were analyzed. Fixed effects were estimated from a four-t...
Daily gains of 8 243 dual-purpose bulls from 100 to 400 days of age during the years 1971 to 2007 were analyzed by random regression models. Orthogonal Legendre polynomials (LP) of degree 4 were appli...
Three varieties of rapeseed namely Foseto, Option500 and Goliath including F2 and F3 generations (crosses among them) were planted in a complete randomized block design for evaluation of genetic varia...
A study was conducted at Jatropha Research Station of Phytosalinity Discipline, Central Salt and Marine Chemical Research Institute, Chorvadla,Bhavnagar, Gujarat, India. The objective was to determine...
摘要畜禽遗传评定是畜禽育种的重要内容。目前畜禽遗传评定方法中应用最广的是基于表型信息的BLUP动物模型。基因组学的发展和应用产生了大量分子遗传标记,结合分子遗传标记信息的遗传评定方法MBLUP随之产生。MBLUP将成为一种快速有效的畜禽遗传评定方法。本文主要介绍了畜禽遗传评定方法的研究进展和发展趋势。 Abstract:Genetic evaluation is one of the most ...
The effect of an upgraded Finnish evaluation model on bias in estimated breeding values for protein yield was investigated. Evaluations based on repeatability animal model and on random regression tes...
The covariance structure was estimated by REML for a joint genetic evaluation of production and reproduction traits for Czech Landrace (58 258 records) and Czech Large White (167 161 records) pigs usi...
Survival Kit V3.12 was used to analyse the length of productive life of cattle in theCzechRepublic. The data set consisted of 230 028 registeredHolstein cows. The model included the time-dependent eff...
