Abstract

|
A total of 120 pigs were used to investigate the effect of feeding probiotics on quality properties of pork. About 6 kg pigs were randomly alloted into one or three experimental diet groups (C: commercial diet feed; T1: 0.1% KBC1121 feed; T2: 0.1% YC2000+0.1% KBC1121 feed). Pigs were slaughtered at approximately 110 kg live weight and chemical composition and physico-chemical characteristics were measured in pork loin. Moisture, crude protein and crude ash were not differences among the treatments. However, crude fat content of T2 was significantly higher than that of other treatments. All of dietary probiotic groups showed significantly higher pH than control. WHC was significantly higher in T1 than other treatments. Cooking loss, shear force value and cholesterol content were not differences among the treatments. In meat color, value was not difference among the treatments, but value were lower in T1 than other treatments. In textrure properties of cooked meat, brittleness, hardness, gumminess and chewiness value were significantly higher in T1 than other treatments. Sensory evaluation was not difference among the treatments. The myristic, stearic and oleic acid content of T2 were significantly higher than those of other treatments. Whereas linoleic acid was significantly lower than other treatments. Unsaturated fatty acid (UFA) was significantly higher in T1 than T2. Essential fatty acid (EFA) and EFA/UFA were higher in the order of T1 > C > T2. In amino acid composition, total and essential amino acid, aspartic acid, threonine, serine, glutamic acid, valine, isoleucine, leucine and lysine level were lower in T2 than other treatments.
