The effect of feeding a phytogenic (Ambitine™FT) with and without added copper on late finishing pig performance
Eight hundred and eighty late finishing pigs (initial BW = 95.2kg) were used to evaluate the effect of feeding a commercially available phytogenic Ambitine™ Feed Technology (Ambitine™ FT) in corn-soybean meal-dried distillers grains with solubles (DDGS) diet on late finisher pig performance. Pigs were allotted in a randomized complete block design into mixed gender pens, with 11 replicates per treatment, 20 pigs per pen, and fed 1 of 4 dietary treatments. Dietary treatments were Control no medication, Ambitine™FT (0.10%), Ambitine™FT (0.10%) + Copper Chloride (150ppm), Copper Chloride (150ppm). Pigs were fed 2 dietary phases, phase 1 was fed from day 0 to 20 and consisted of corn-soybean meal-12.5% DDGS formulated to 0.70% TID lysine, phase 2 was fed from day 20 to 42 and consisted of corn-soybean meal-10% DDGS formulated to 0.65% TID lysine. Data were analyzed using the Mixed procedure in SAS. There were no difference in pig performance in period 1 day 0 to 20. Total gain for period 2 day 20 to 42 tended to be increased (P=0.08) with Ambitine™FT and Ambitine™FT + Copper Chloride treatments when compared to the Control and the Copper Chloride treatment was intermediate (18.40, 19.99, 19.60, 19.24 kg, treatments respectively). Period 2 ADG was increased (P=0.04) with Ambitine™FT and Ambitine™FT + Copper Chloride treatments when compared to the Control and the Copper Chloride treatment was intermediate (837.63, 908.91, 891.66, 862.15 g/d, treatments respectively). Period 2 ADFI was not different between treatments (2.979, 2.954, 2.912, 2.894 kg/d, treatments respectively). Period 2 Gain:Feed was increased (P=0.01) with Ambitine™FT, Ambitine™FT + Copper Chloride, and Copper Chloride treatments when compared to the Control (0.281, 0.308, 0.306, 0.299, treatments respectively). Overall day 0 to 42 ADG was not different between treatments (913.45, 941.60, 942.96, 929.34 g/d, treatments respectively). Overall ADFI was not different between treatments (2.840, 2.790, 2.802, 2.805 kg/d, treatments respectively). Overall Gain:Feed for day 0 to 42 was increased (P=0.03) with Ambitine™FT and Ambitine™FT + Copper Chloride treatments when compared to the Control and the Copper Chloride treatment was intermediate (0.322, 0.337, 0.337, 0.331, treatments respectively). Supplementation of Ambitine™FT with or without copper chloride to late finishing pigs resulted in improved feed conversion.
