Effects of MSM (Methyl Sulfonyl Methane) Supplementation on Growth Performance and Digestibility of Ca and N in Pigs

摘要

For the EXP 1, the objective of this study was to determine the effect of MSM (methyl sulfonyl methane) supplementation on growth performance and nutrient digestibility in pigs. Sixty crossbred (Landrace x Yorkshire X Duroc) pigs (48.15±0.15 kg average initial body weight) were used in a 35 days growth assay. Dietary treatments included 1) Control (basal diet), 2) Tl (basal diet + 0.01% MSM) and 3) T2 (basal diet + 0.02% MSM). For overall period, average daily gain, average daily feed intake and feed efficiency were not significantly different among the treatments (p>0.05). Digestibilies of DM, N, Ca and P were not significant defferences (p>0.05). For the EXP 2, the objective of this study was to determine the effect of MSM and antibiotic supplementation on growth performance and nutrient digestibility in pigs. One hundred crossbred (Landrace x Yorkshire xDuroc) pigs (33.85 + 0.15 kg average initial body weight) were used in a 42 days growth assay. Dietary treatments included 1) Control (basal diet), 2) Tl (basal diet+ 0.05% neomycin sulfate, 0.055% oxytetracycline), 3) T2 (Con dict + 0.01% MSM) and T3 (Tl + 0.01% MSM). For overall period, average daily gain and average daily feed intake of pigs fed T3, T2 diets were higher than those of CON diet (p<0.05). Average daily gain was not significantly different between T2 and T3. However, food efficiency of pigs fed CON was the highest among the treatments (p<0.05). Pigs fed T3 diet increased nutrient digestibility compared to other treatments (p<0.05). In conclusion, the results suggest that the dietary addition of MSM and antibiotics into diets for pigs affect growth performance and nutrient digestibility.
