The Effects Of Dietary IMO And CBM On Sows Production Performance

The present study was conducted to investigate the effects of dietary IMO and CBM on sows reproductive performance, In the hope to improve the reproductive performance of sows, serum biochemical indices, digestibility of nutrient, The balance of gastrointestinal tract microecological bacteria, serum immunoglobulins, and Indirectly enhance the growth performance of piglets, the body’s immune resistance, reduce piglet diarrhea rate, etc.Through the 2×4 factorial design, The two level of IMO (Omg/kg,0.50mg /kg),and four level of CBM (Omg/kg,0.05mg/kg,0.1 Omg/kg,0.150mg/kg). This test selects no significant difference of the tire (5-9), Body condition, backfat binary mixed 48 sows(P>0.05),divided into eight groups of three replicates of 2 sow.Stage 1 is from pregnancy 75d to 90d to promote the development of b reast.Stage 2 is from pregnancy 91d to 114d to promote the rapid of growth a nd development of the fetus,to the end of the 21 days of lactation.The results showed that:(1) Reproductive performance:Add 0.5% IMO,0.5% IMO+0.05CBM%,0.5% IMO+0.10CBM% on average piglet birth weight was significant effect level (P<0.05). In terms of litter weight at birth, Group 6 (0.5% IMO+0.10CBM%) of the average piglet litter weight at birth was significant effect level (P<0.05). In healthy rate, Group 6 (0.5% IMO+0.10CBM%) and significantly higher than the first and third group (P<0.05).(2) Sows body condition indexes:Adding 0.15% CBM can increase sow feed intake significantly(P<0.05). Univariate adding 0.5% IMO makes sows lochia average duration significantly decreased (P<0.05). In univariate and add CBM and IMO+ CBM interactions showed significant (P<0.05). In estrus interval. Adding 0.10% CBM,0.15% CBM, estrus interval 0.15% CBM+ 0.5% IMO group were significantly lower (P<0.05), and in the IMO+ CBM interaction terms showed significant (P<0.05).(3) Lactation performance:In terms of milk protein,5,6,7 group (IMO+ CBM in combination group) were significantly higher (P<0.05). In terms of milk fat,6 were significantly higher (P<0.05). In terms of non-fat solids,3,6 group were significantly higher (P<0.05). On the whole, adding IMO and CBM can effectively improve the nutritional level of the sow’s colostrum. Butterfat content aspect, IMO and CBM interactions performed significantly (P<0.05). Adding non-fat solids content of 0.05% CBM, and 0.15% CBM group were significantly higher than 0% CBM group (P<0.05).(4)The apparent nutrient digestibility:In terms of crude protein,group 6,7 was significantly higher than group 1 (P<0.05). In terms of crude fiber, group7 was significantly higher (P<0.05). In terms of calcium, Group 6 were significantly higher (P<0.05). In terms of phosphorus, the first group was significantly higher than group 6,7 and 1 (P<0.05). Univariate add IMO, CBM on protein, phosphorus digestibility was significantly (P<0.05), and the IMO and CBM interaction effect on phosphorus digestibility was significantly (P<0.05).(5) Sow serum biochemical parameters:In TP, Glo aspect, the first group are the highest total protein content, and they were significantly higher than group 3,7 (P<0.05). In the A/G ratio aspect, the highest ratio in Group 7. In blood sugar, group 3,4,5 were significantly higher. Univariate and interaction effects showed that adding 0.05% CBM TP group was significantly higher than 0.15% CBM group (P<0.05). Adding 0.05% CBM Group cholesterol levels were significantly higher than 0% CBM and 0.10% CBM group (P<0.05). Adding 0.15% CBM TG levels were significantly higher than that added 0.05% CBM group (P<0.05).(6) Lactating sows serum immune indexes:The first group 3,4,6 IgG levels were significantly higher (P<0.05), the level of immunity to Group 6 is the highest.3,4,5 group IgM were significantly higher (P<0.05).3 and 4 of IgA were significantly higher (P<0.05). Univariate added 0.5% IMO IgG group was significantly higher than 0% IMO group (P<0.05), and individually add CBM, IMO+CBM interactions showed significant (P<0.05). IgM levels in the IMO and CBM interaction terms showed significant (P0<0.05).(7) Lactating sows Fecal indicator bacteria:It was significantly higher (P<0.05) in the third and fifth groups Fecal Bifidobacterium. The first group of lactic acid bacteria levels 1,5,7 fecal samples contained significantly higher (P<0.05). Univariate added 0.15% CBM group of bifidobacteria was significantly higher than 0% CBM group (P<0.05), and the performance in terms of IMO+CBM interaction significantly (P<0.05). Add 0.05% CBM group number of lactic acid bacteria fecal samples were significantly higher than 0% CBM group (P<0.05).(8) Growth performance of piglets:Group6,7 piglets average litter weight were significantly higher (P<0.05). The first group 3,5,6,7 average weaning weight were significantly higher (P<0.05).6,7 Group diarrhea were significantly lower than the control group and the group 1,4 (P<0.05) single factor is added an average weaning weight of 0.15% CBM group was significantly higher than 0% CBM group and 0.05% CBM (P<0.05), and the performance in the IMO+CBM interactions significantly better than single factor (P<0.05). Univariate added 0.15% CBM group average weaning weight was significantly higher than 0% CBM group and 0.05% CBM (P<0.05), and the performance in terms of IMO+CBM interaction significantly (P<0.05). Adding diarrhea rate level of 0.50% IMO group were significantly lower than 0% IMO group (P<0.05), adding diarrhea rate level of 0.15% CBM group and 0.10% CBM group was significantly lower than 0% CBM group (P<0.05).(9) Biochemical indices in terms of piglets:Adding 0.50% IMO,0.5%IMO+ 0.05CBM%,0.5% IMO+0.10CBM% of piglets affect the results of the indicators is relatively good, and adding 0.50% IMO GLU levels were significantly higher than 0% IMO group (P<0.05).(10) Adding 0.50% IMO,0.5% IMO+0.05CBM%,0.5% IMO+0.10CBM% immunoglobulin Index of Piglets relatively good, and individually add IMO aspects of performance significantly (P<0.05). Adding 0.15% CBM group of IgA was significantly higher than 0.10% CBM group (P<0.05), and individually adding IMO performance significantly (P<0.05).On the whole, the single factor adding IMO, univariate adding CBM% in terms of interaction with 0.5% IMO,0.5% IMO+0.05CBM,0.5% IMO+0.10CBM group effect is more prominent, and reproductive performance of sows and piglets growth performance greater impact.
