|
This study was performed to evaluate the effects of medicinal herbs on characteristics and qualities of pork for 6 months using 102 post-weaning piglets, To improve the bod gain and feed efficiency rate, post-weaning piglets were fed with medicinal herbs from 4 to 10 weeks after birth, while grower pigs for 60 days before slaughter. Daily body gain of piglets of experimental group was higher(493.1g) than control(447.8g), with feed demand index 1.49 versus 1.6 times in control, indicating. The more pigs were fed with herbs, the higher body gain was observed. Among carcass characteristics, dressing percentage and backfat thickness were higher in experimental group(68.26% and 14.52mm) than control(67.39% and 14.36mm). Experimental group(0.5% medicinal herb-fed) produced more A class carcass. In fatty acid analysis, meats of experimental group contained less saturated(more unsaturated) fatty acids than control. Especially, palmitic acid, a precursor of cholesterol, was less and oleic acid was more contained than control. In amino acid analysis, essential amino acids(methionine and isoleucine) were increased in meats of experimental group. In concolusion, feeding medicinal herbs has effects such as increased body gain, improved feed demand, and carcass class on piglets and improved meat quality on growers.
