Comparative studies of microorganism products, mixed herb, Biotronic, choline chloride and beta-agonist on quality of pork

Comparative studies of the effects of supplementation with Microorganism Products, Mixed Herb, Biotronic, Choline Chloride and Beta-agonist in pig dictary fomulations on quality of pork were carried out. Forty two castrated male Largc White at 30 kgs of initial weight were randomized to 7 experimental groups; group 1:control group; group 2: supplemented with Effective Microorganism Products 1 percent; group 3:supplemented with Mixed Herb;group 4:supplemented with Biotronic 0.2 percent; group 5:supplemented with Choline Chloride 0.15 percent; group 6: supplemented with Salbutamol (8 ppm) 0.1 percent and group 7:supplemented with Salbutamol (12 ppm) 0.1 percent. In group 6 and group 7, salbutamol were supplemented to the pigs of 70 kgs body weight. Pigs were killed at approximate 100 kgs body weight. Blood were collected for complete blood count (CBC) and lipid profile analysis. Three portions of pork (Top Round, Loin Roast and Pork Fillet) and subcutaneous backfat were collected to study the nutritional value and fatty acid composition including the cholesterol content. There were no significantly differences of CBC and nutritional value of three portions of pork in among treatments. Supplementation with Mixed Herb, Biotronic or Choline Chloride in pig diets reduced the cholesterol content of subcutaneous backfat, but not significantly differences when compared with control and salbutamol supplemented groups. In Cholinc Chloride supplemented group, plasma cholesterol content was lower than other groups (p0.01). Fatty acid composition of subcutaneous backfat in Choline Chloride supplemented and control groups were found that total percentage of saturated fatty acids were higher, but total percentage of unsaturated fatty acids were lower than salbutamol supplemented group (p0.01). Therefore, it is concluded that supplementation with Microorganism Products, Mixed Herb, Biotronic, Choline Chloride or Beta-agonist in pig dietary formulations have no effect on quality of pork. However, the cholesterol content of pork still require additional studies.
