The present study investigated the effects of microbial additives producing antimicrobial and digestive-enzyme activities on the growth performance, blood metabolites, and fecal microflora of weaning pigs from 21 to 42 d of age. A total of 144 weaning pigs (1:1 ratio of gilt and boar; 21 d of age; 7.40 ± 0.53 kg of average body weight) were randomly distributed into four supplementary levels of microbial additive (0 vs. 0.5 vs. 1.0 vs. 1.5% of fresh weight) with three pens of replication, consisting of 12 weaning pigs per pen. All weaning pigs were maintained with the same basal diet for 21 d. Blood and feces were subsampled at day 21. Feed efficiency tended to increase linearly (p = 0.069) with an increasing supplementation level. Insulin, insulin-like growth factor 1, and blood glucose presented a quadratic effect (p < 0.05) with an increasing supplementation level, and these blood metabolites were highest at the 1% supplementation level. Immunoglobulin G in blood increased linearly by (p < 0.05) increasing the supplementation level. Salmonella and Escherichia coli in feces were decreased linearly by (p < 0.05) increasing the supplementation level. In conclusion, supplementation of microbial additive at 1.0% improved the feed efficiency, blood metabolites, and fecal microflora of weaning pigs.

Abstract Two experiments were conducted to evaluate the effect of creep feed (CF) and its nutrient level on growth performance of suckling and weaning pigs. In Exp. 1, eight litters (d 20 of age) were allotted to 2 treatments based on breed, litter size and weight as follows: no-CF (n=3) and CF (n=5; offered from 8 days before weaning). At weaning (d 28 of age), the pigs were divided into 3 treatments (6 pigs/pen, 3 replicates; initial BW: 9.66±0.34 kg) balanced with gender, weight, and breed as follows: eaters, noneaters, and no-CF. In Exp. 2, seven litters (d 12 of age) were allotted to 2 treatments as follows: HN (n=4): CF with fish meal (3%), blood meal (2.4%), and whey (15%), and LN (n=3): CF without those ingredients. At weaning (d 25 of age), eater pigs were divided into 2 treatments (6 pigs/pen, 3 replicates; initial BW: 7.53±0.97 kg) as follows: HN-eaters and LN-eaters. In both experiments, the pigs were fed a common nursery diet for 21 days. The CF was mixed with 1% Cr2O3 to measure fecal color for eater/noneater categorization. Piglet weaning weight was not different among eaters and non-eaters in both experiments (in Exp. 1, P=0.99; 9.35, 9.33, and 9.20 kg for eaters, noneaters, and no-CF, respectively). There was no difference on overall nursery growth performance in both experiments. The HN-eaters tended to have greater ADG (P=0.08; 0.506 vs. 0.427 g/d for HN-eaters and LN-eaters, respectively) and G:F (P=0.09; 0.889 vs. 0.717, respectively) than LN-eaters in d 7-14 postweaning in Exp. 2. The CF intake and percentage of eaters/litter (P=0.60; 85.6 and 80.87% for LN and HN, respectively) in Exp. 2 were not different between treatments. In conclusion, CF did not affect overall piglet growth in suckling and nursery phases, but nutrient level might affect early nursery pig growth.

Abstract The objective of this study was to evaluate the effects of dietary supplementation of coated omega-3 fatty acid (n-3 CFA) by corn cob power silica on performance of weaning pigs. A total of 200 weaned pigs [(Landrace x Yorkshire) x Duroc, average initial body weight at 6.97 ± 1.22 kg] were randomly assigned to four experimental treatments in a 6-week experiment in 3 phases as follows: CON, basal diet; 2) 0.3CFA, CON + phase 1(0.3% n-3CFA), phase 2(0.2% n-3CFA), phase 3(0.1% n-3CFA); 3) 0.6CFA, CON + phase 1(0.6% n-3CFA), phase 2(0.4% n-3CFA), phase 3(0.2% n-3CFA); 4) 0.9CFA, CON + phase 1(0.9% n-3CFA), phase 2(0.6% n-3CFA), phase 3 (0.3% n-3CFA). Each treatment had 10 replicates with 5 pigs (three gilts and two barrows) per replicate. The data were analyzed using the GLM procedure of SAS as a randomized complete block design. Pen served as the experimental unit. Linear, quadratic and cubic polynomial contrasts were used to examine effect of dietary treatment with coated n-3FA in the basal diet. Variability in the data was expressed as the standard error of means and P&lt; 0.05 was considered to statistically significant. Increasing the level of n-3CFA in the diet linearly increased ADG and G/F of pigs (Table 1). Increasing the level of n-3CFA showed a linear increment in the digestibility of DM (83.59, 84.38, 85.13, 85.89 %) whereas nitrogen digestibility (81.79, 82.38, 82.96, 83.64 %) showed a trend (linear effect, p=0.0594) at the end of experiment. The fecal lactobacillus count was increased (7.22, 7.27, 7.33, 7.35 log10cfu/g) with the increase in the supplemental level of n-3CFA (linear effect; p&lt; 0.05). However, there were no differences in the concentration of serum haptoglobin, or fecal E. coli, Clostridium and Salmonella counts despite the increase in n-3CFA levels in the diet. Supplementation of the diet with coated n-3 fatty acids positively affected growth performance and digestibility of dry matter and nitrogen, and enhanced the count of lactobacillus in weaning pigs.
