Study on the breeding objective traits and selected traits for beef line of Luxi cattle;

The Investigation and Study of Maintenance of Breeds Present Situation and Exploitation Direction of Luxi Cattle in the Huanghe River Delta;

The Study of Somatic Cells Cloning Technology in Luxi Cattle s Conservation;

The sequences of MC1R gene of Chinese Holstein Cattle,Luxi Yellow Cattle and Bohai Black Cattle were cloned and sequenced in this experiment.

One hundred ninety healthy quarantined Luxi Yellow cattle of 3~5 year-old were selected and fed in same location.

In this paper, the adaptation of Luxi yellow cattle under higher temperature environment was studied after it was introduced from Shandong province to Qiyang.

Genetic polymorphisms of four Y-STR loci in Luxi cattle;

PCR-RFLP technique was used to analyze the relationship between the polymorphisms of IGFBP3 gene and beef performance in 24 Luxi cattles and 19 Jinnan cattles.

We measured the body weight,growth index,slaught performance and reproductive character of cow from 258 animals(bull) and 625(cow) animals in Xiangxi cattle breed.

The growth curves of female Xiangxi cattle were fitted by the equation of Logistic and Gompertz using 562 female Xiangxi cattle s weight data.

Outside this research from Xiangxi cattle production performance, the Xiangxi cattleSimmental and the shorthorn improves the Xiangxi cattle effect as well as the Xiangxi cattleinducts the blood selective breeding effect (F_1 generation of production performance) and so onfour aspects to study the Xiangxi cattle s growth developmental mechanism and the hybrid useeffect.

Research and Extension on Crossbreeding Improvement Technology of Xiangxi Yellow Cattle;

Xiangxi yellow cattle were analyzed by using of six microsatellite markers in this study.

Taking the example of the practice in Xiangxi yellow cattle, the change of main works and working styles in breed conservation of yellow cattle was discussed and three breed conseration strategies of Xiangxi yellow cattle evaluted.
