植物乳杆菌和干酪乳杆菌对仔猪生长性能、器官指数及小肠形态的影响
Effects of Lactobacillus plantarum and Lactobacillus casei on Growth Performance, Organ Index and Intestinal Morphology of Piglets
摘要
Abstract
The experiment was conducted to study the effects of Lactobacillus plantarum and Lactobacillus ca-sei on growth performance, organ index and intestinal morphology of piglets. A total of 15 litters piglets ( Yorkshire × Landrace) at age of 7 days were randomly assigned to 3 groups with 5 replicates per group and 1 litter ( 8 to 10 piglets) per replicate, including the control group orally administrated with distilled water, Lac-tobacillus plantarum group orally administrated with Lactobacillus plantarum and Lactobacillus casei orally ad-ministrated with Lactobacillus casei. The experiment started at day 7 and ended at day 35 after birth. The pig-lets were slaughtered on day 21, 24 and 35 after birth for sampling. The results showed that compared with the control group, Lactobacillus plantarum and Lactobacillus casei significantly increased average daily feed intake ( ADFI) and average daily gain ( ADG) and decreased feed/gain ( F/G) after weaning ( P<0.05) , however, no effects were found before weaning for both tested strains (P>0.05). Organ indexes of piglets at 35 days such as spleen and thymus were also significantly increased in the two tested strains group (P<0.05), and stomach index and large intestine index were not affected. ( P>0.05) . Lactobacillus plantarum and Lactobacil-lus casei improved the villus development of jejunum and ileum of weaning piglets. The findings indicate that both Lactobacillus plantarum and Lactobacillus casei have potential benefits to the growth performance and in-hibition of diarrhea of piglets. However, further study of mechanisms and a large number of repeated experi-ments are needed for the evaluation of both tested strains for clinical use.关键词
