Abstract

This experiment was conducted to research the effects of dietary Lactobacillus on growth performance, serum biochemical indices and the number of fecal microorganisms of sows and suckling piglets through drinking. Forty late gestation (81 to 85 d) sows with the same parity were randomly divided into 4 groups with 10 sows per group. The Lactobacillus liquid (live Lactobacillus concentration was ≥ 1×10⁹ CFU/mL) was fed per pig per day for sows in experimental groups: 200, 250 and 300 mL, respectively, and the control group was 0 mL, and that for 4 groups of piglets were 5, 10, 15 and 0 mL, respectively. The durations of the test were 80 and 7 days, respectively. The results showed as follows: 1) compared with control group, the score of sow body condition at weaning in 250 mL group was significantly improved (P<0.01). Both normal estrus and fecundation rates in experimental groups were 100.00%. 2) Compared with control group, the weight of piglets at weaning, average daily gain and score of piglet skin development condition in experimental groups were significantly improved (P<0.01); diarrhea rate showed a decreased tendency. 3) Compared with control group, feeding Lactobacillus had a significant effect on the content of immunoglobulin G in colostrums (P<0.05), moreover, the content of milk protein, milk fat and serum antioxidative indexes of the colostrums also had increased tendency. In the 300 mL group, the number of E.coli and Salmonella were significantly lower than those in control group (P<0.05), nevertheless, the number of Lactobacillus was significantly higher (P<0.05). These results prove that feeding Lactobacillus can improve intestinal microorganisms and healthy conditions of pigs; moreover, it can improve reproduction performance of sows and growth performance of suckling piglets.
