Abstract:
In a completely randomized design, the effect of nanochitosan from chitosan as an alternative to antibiotics was evaluated using 4 liters per treatment such that the four dietary treatments had 32 piglets in each group. The dietary treatments were creep feed (T1, control), creep feed with antibiotic (T2), creep feed with 1.0% chitosan (T3), creep feed with 0.1% nanochitosan (T4) supplementation. The piglets were weaned at 42 days and fed for another 14 days by selecting at random 6 piglets for each treatment. Grower ration (T1) was supplemented with antibiotic (T2), 5.0% chitosan (T3), 0.5% nanochitosan (T4). During pre-weaning phase, the initial piglet weight (kg), final piglet weight (kg), average daily gain and weight gain were significantly (P<0.01) different among treatments. During grower phase, the total weight gain (kg) and average daily gain (kg) of pigs were higher (P<0.01) in T3 and T4. At 10th day, the villi height (µm), crypt depth (µm) and ratio of villus height to crypt depth (VH/CD) in duodenum, jejunum and ileum and the E. coli and Salmonella count (cfu/g) was not significantly different among treatments T1 to T4. At 42nd day, the villi height (µm) in duodenum was significantly higher (P<0.01) in pigs fed on T4 ration but in jejunum and ileum, height of villi (µm) was significantly higher (P<0.01) in pigs fed on T3 and T4 rations. The crypt depth (µm) in duodenum was significantly lower (P<0.01) in pigs fed on T2 ration, whereas, in jejunum and ileum the crypt depth (µm) was significantly lower (P<0.01) in pigs fed on T3 and T4. The ratio of villus height to crypt depth (VH/CD) in duodenum, jejunum and ileum was significantly higher (P<0.01) in pigs fed on T4 ration. The E. coli (P<0.01) and Salmonella (P<0.05) count in pigs fed on T4 ration was significantly lower. At 57th day, the height of villi (µm) and ratio of villus height to crypt depth (VH/CD) in duodenum, jejunum and ileum in pigs fed on T4 ration was significantly higher (P<0.01). The crypt depth (µm) in duodenum, jejunum and ileum was significantly lower (P<0.01) in pigs fed on T4 ration than in other treatments. The E. coli and Salmonella count (cfu/g) was significantly lower (P<0.01) in pigs fed on T3 and T4 rations.
