Effects of tribasic copper chloride (TBCC), Saccharomyces cerevisiae fermentation product (YFP), and narasin (NAR) supplementation on growth performance of 12 to 25 kg pigs
A total of 929 pigs were used in a 28-d experiment to determine the effects of TBCC (Intellibond C, Micronutrients), YFP and NAR (Skycis, Elanco Animal Health) alone and in combination on growth performance of 12 to 25 kg pigs. Twenty-one days post-weaning, pens of pigs were allotted to one of 6 dietary treatments (TRT) in a randomized complete block design based on previous TRT and BW with 24 to 26 pigs per pen and 6 replicates per TRT. Data were analyzed using GLM procedure of SAS. All diets were Corn-SBM- 10% DDGS based, fed in pellet form (3.17 mm.), and formulated to contain 1.25% SID LYS. The dietary TRT were; 1) Control (C), 10 ppm Cu sulfate; 2) C + 142.5 ppm TBCC; 3) C + 0.05% YFP; 4) C +142.5 ppm TBCC + 0.05% YFP; 5) C + 19.91 ppm NAR; 6) C + 142.5 ppm TBCC + 0.05% YFP + 19.91 ppm NAR. Overall (Table 1.), pigs fed TRT 6 had the greatest ADG, followed by TRT 2, 4, and 5, with TRT 1 and 3 being the poorest. Pigs fed TRT 6 had the highest ADFI (P < 0.05) compared with pigs fed TRT 3, with all other TRT being intermediary. Feed efficiency was greatest (P < 0.05) for pigs fed TRT 6 and poorest for pigs fed TRT 1 and 3. Pigs fed TRT 2 and 5 had similar (P < 0.05) GF to TRT 6 and 4, but TRT 4 was not similar (P > 0.05) to TRT 6. In summary, feeding TBCC or NAR alone can increase growth performance compared with pigs fed the C and YFP, while the combination of TBCC, NAR, and YFP were additive and resulted in the greatest improvement in ADG, ADFI, and GF.
