The DNA in tissue of ear skin of 91 Danish Landrace were collected to test the gene and genotype frequencies of porcine Malignant Hyperthermia Syndrome(MHS) locus with the method of PCR RFLP.

In the enforcement period of the“ninth five-year plan”,open nucleus breeding system was utilized in the process of selection for America-line Landrance in Nanchong breeding farm.

Studies on Optimal Levels of Crude Protein and Lysine for the Sow during Lactation and Observation of Adaptability in Sweden Landrace;

Objective To explore the normal values of blood routine and biochemical indexes of Chang-Bai piglet,and to provide the normal values for the experimental studies.

Histoligical observation on the intestinal mucosa of Jiuyang pig,Jianbai pig and Changbai pig at the different ages;

<Abstrcat> Add 0,5,10,25,50 and 100　ng/mL platelet-activating factor (PAF) into the artificially gathered seminal fluid of Changbai pig and breed them in 37℃ thermostatical water for 5,15,25,35,45 and 60 minutes.

The leg and feet triats of Min pig compared with Landrace pig and their crossbreed;

Myogenin mRNA abundance in longissimus dorsi muscle of Jinhua pig and Landrace pig

A total number of 6733 litter records of littering and breeding of Landrace pig collected at Hangzhou (stud or breeding) pig farm from 1996 to 2001 are analysed in this study.
