Regulation of Amylase-Glucose-Insulin via Dietary Supplemental of Zinc in Weanling Pigs

The impact of supplemental Zinc on Amylase Glucose - Insulin regulation were studied in 15 numbers of weanling pigs 87.50 percent Hampshire (Hampshire X Meghalaya local) weaned at 60 days of age, apparently healthy with uniform body weight (10.60 to 10.70 kg) were selected for the experiment and were randomly allocated into 3 treatment groups viz. Group A (100ppm Zn) as per the recommendation of NRC (1998) which was considered as control, B (200ppm Zn) and C (300ppm Zn) comprising 5 weanling pigs in each group. The experiment was conducted for a period of 4 months (2 to 6 months of age). The body weight gain (BWG) was measured and serum sample were collected at fortnightly interval from 2 to 6 months of age. The BWG, serum zinc concentration, amylase activity and insulin concentration was found significantly (Pless than0.01) higher in group C followed by B whereas the lowest was in group A at the end of the experiment (6 month of age). Significantly (Pless than0.01) highest serum glucose concentration was observed in A group whereas, lowest was in C group. The variations in response to dietary supplemental zinc among treatments could be related to the stimulation of Amylase - Glucose insulin pathway by dietary zinc supplementation to enhance the body weight.
