293 – Effects of dietary hop beta-acids or colistin on the performance nutrient digestibility and intestinal health of weanling pigs (Research paper – Sbardella – 2016)Click here for resource
In Significant Impact Groups: Feed / gut health \ Feed additives and supplements; Specific alternatives
Species targeted: Pigs;
This study evaluated the effects of hop (Humulus lupulus) beta-acids or colistin on several parameters, namely body weight (BW), Average feed intake (ADFI) Average daily gain (ADG), gain:feed ratio (G:F). Two hundred 21-d weaned pigs fed diets supplemented with 0 (negative control), 120, 240, or 360 mg/kg hop beta-acids, or with 40 mg/kg colistin (antimicrobial control) during a 35-d experiment. Increasing dietary levels of hop beta-acids improved linearly BW, ADG, G:F,and digestibility in weanling pigs. The colistin treatment improved BW, ADG, and G:F compared to the negative control. No difference in growth performance was observed between hop beta-acids levels and colistin. Overall, the occurrence of diarrhea was lower for colistin, negative control, and 360 mg/kg hop beta-acids than for other levels. In conclusion, dietary hop beta-acids concentrations up to 360 mg/kg improved weanling pig growth rate by affecting the efficiency of feed utilization, as well as observed for colistin.
