چکیده

Abstract To evaluate the association of fatty acids, prebiotics and zinc proteinate (Viligen NE) in weaned piglet diets without AGP, 80 piglets averaging 6.69±0.19 kg (21-days old) were distributed randomized blocks design. Eight replicates one male female used for each five treatments: positive control (an antibiotic growth promoter; 0.02% Halquinol 60%), negative (no additive) 3 levels Viligen NE (0.10, 0.14 0.18%). Daily feed intake (DFI), average daily gain (ADG) conversion (FC) determined from 21 to 35 36 49 days age. At end experiment, jejunum content was collected Lactobacillus sp Enterobacteria counts, cecum Bifidobacterium Clostridium perfringens counts. The had worst ADG (P=0.0004) FC (P=0.0357) (P=0.0196) days. All showed same performance as Halquinol, both portions feeding period. optimal ADG, estimated by quadratic broken line models, 0.137 0.100%, respectively. Significant linear relationships found between (negative days) (positive 46 days). Jejunal count least (P=0.0001). Cecal greater (P=0.0063) 0.18% NE, while less (P=0.0008) 0.10 NE. Quadratic models jejunal with 0.110 0.070% respectively, cecal at 0,096 0,079% Under conditions this 0.10% or supported detrimental effects on intestinal microbiota populations.
