A study of the effect of extra D.L. - methionine hydroxy ana log, and capsaicin to nursery pigs by analysis of the characteristics of pig manure Planning of randomized complete (Completely randomized design;CRD) by studying the effects of supplementation of D.L. - methionine hydroxy ana log, and capsaicin in diet on production performance of pigs in kindergarten. The pH of the gastrointestinal tract in pigs infected Escherichia coil kindergarten in the intestine.Using experimental animals as pigs. The castrated males, age 6 weeks of 96, divided into 4 groups 6 repeatedly, each 4 period 6 week. To supplement the theo - methionine hydroxy ana log, and capsaicin is divided into 4 level is a group 1.LMA capsaicin (control group) and group 2 extra LMA 0% and capsaicin 2.5 ppm group 3 accessories and LMA 0.25% capsaicin 2.5 ppm and group 4 accessories and LMA 0.5% capsaicin 2.5 ppm was not มีผลต่อสมรรถภาพ production (P > 0.05). The pH of the gastrointestinal tract (P > 0.05) CFU Escherichia coil in colon and the feces of pigs Kindergarten (P > 0.05). So the theo - methionine hydroxy ana log, and capsaicin to kindergarten pigs not different significantly.
