Studies on the Pork Characteritics of Fuzhou Black Pig,the Meat-type Pig and the Cross-bred Pig

The meat hereditary character of Fuzhou Black Pig,Duroc,New Landrance,Sige and the cross-bred pig,altogether 12 breeds or cross-breeds of 86 pigs,was studied on this paper.The result shows that the meat indexes of the local Fuzhou Black Pigs are higher than that of all kinds of introduced rneat pigs.The rneat pH value of Fuzhou Black Pig is high,which is 6.24 ± 0.16;the colour of meat is in nomorl range,which is 3.33±0.21;the marbling of meat is distributed well,which is 3.33±0.21;the ratio of water loss(%)is low,which is 19.28±5.49;the meat fiber is thin and its diameter i,43.05±6.12μm.It shows at thexame time that in the introduced pigs the pork characteritics present sharp differences.The result also shows that in the cross breds,used Fuzhou Black Pigs female parent and the introduced pigs as male parent,the meat indexes of the crossbred pigs are hetween the average value of the two parents,but with their own characters,The meat quality of crossbreds DF and DNF is the highest by tising Duroc as the terminal male parent.When the leanmeat type pigs are developed and tixed,the male parent must be selected with great care in order to prevet PSF meat.
