Title: Study on Germplasm Characteristics of Jiangkouluobo Pig
Abstract: The results from determining partial germplasm characteristics of Jiangkouluobo pig showed that the mean litter size,mean birth weight per piglet,mean 21-day litter weight and mean 2-month weaning weight of first farrowing sow were(4.96±1.01),(0.60±0.08)kg,(11.87±3.08)kg and(9.98±1.82)kg respectively,the mean litter size,mean birth weight per piglet,mean 21-day litter weight and mean 2-month weaning weight of multiparity sow were(8.95±1.06),(0.65±0.10)kg,(15.65±3.78)kg,and(10.23±2.31)kg separately,the mean body weight of sow with 4-month and sow with 6-month was(28.74±3.86)kg and(46.44±5.56)kg,the mean body weight of boar was(21.20±1.38)kg and(37.76±7.47)kg and the growth and development speed of the sow was higher than the boar.Jiangkouluobo piglet with 3-month age should be fattened for 120d and the mean daily gain is(418.11±14.56)g.(1kg gain consumes(3.19±0.13)kg concentrated feed and 1.80kg green feed.The dressing percentage,lean meat percentage,fat thickness,eye muscle area,hind leg proportion,flesh color score,marbling score,water loss rate and cooked meat rate are(69.58±5.01)%,(41.35±4.98)%,(3.38±1.20)cm,(16.92±3.70)cm2,(0.26±0.12)cm,(25.62±0.85)cm,(3.17±0.40),(3.33±0.51),(18.17±2.58)% and(65.90±1.38)% respectively,which indicates that the meat quality of Jiangkouluobo pig is excellent.
