Effects of tributyrin on growth performance and diarrhea rate in nursery pigs
A total of 180 ternary hybrid"Duroc×Landrace×Yorkshire"nursery pigs the average weight of about 8 kg, evenly divided be-tween males and females, were randomly divided into 3 groups, with 5 replicates in each group and 12 piglets in each replicate. The experiment lasted for 21 days, divide into columns and conducted in the same nursery house while the experiment began simultane-ously. Each group was fed with a basic diet (control group A), supplemented with 1 kg/t of doxycycline (group B), and supplemented with 0.2% tributyrin (group C), the experiment was conducted to study the effects of tributyrin on the growth performance and diarrhea rate of nursery pigs. The results showed that in terms of average head weight gain and daily weight gain, there was a very significant difference (P<0.01) between group A and group B and C. Group B and group C were about 6.6% and 11% higher than group A re-spectively;The difference between group B and group C is also extremely significant, with group C being about 4% higher than group B. In terms of diarrhea rate, group B had a significantly lower diarrhea rate than group A (P<0.05), group C had a significantly lower diarrhea rate than group A (P<0.01), and there was no significant difference in diarrhea rates between group B and group C (P>0.05). As a control group, the diarrhea rate of group A was 43.5% and 69.5% higher than that of group B and group C, respectively. The di-arrhea rate of group C was also 46% lower than that of group B. These results indicated that adding antibiotics and tributyrin to diets could greatly improve the average head weight gain and daily weight gain of nursery pigs, reduce the diarrhea rate of piglets, and adding 0.2% tributyrin was significantly better than adding antibiotics, which could to some extent replace antibiotics for addition.
