- Abstract
The article aim of experiment was to study the effect of fructooligosaccharides on rumen fermentation parameters in suckling lambs. Forty-four lambs with similar body weights at 15 days of age were randomly divided into four groups: no fructooligosaccharides were added to the starter diet of the control group, and 0.5%, 1% and 1.5% fructooligosaccharides were added to the starter diet of the experimental groups Ⅰ, Ⅱ and Ⅲ, respectively (experimental treatment). All lambs were weaned at 60 days of age, which was recorded as d 0. Rumen fluid was collected before morning feeding on day 0, 3, 7 and 14 to determine rumen fermentation parameters. After weaning, the lambs were fed until 74 days of age for a total of 59 d. The results showed that: ① the treatment and time significantly (P<0.05) affected rumen pH and ammoniacal nitrogen (NH3-N). The rumen pH and NH3-N of the test Ⅱ group were significantly lower than those of the control group on day 3, 7 and 14 (P<0.05); with the extension of weaning time, pH increased and then decreased, and there was a tendency for NH3-N to decrease. Treatment × time had no effect on pH and NH3-N (P>0.05). ② Treatments significantly affected total volatile fatty acids (TVFA), acetic acid, propionic acid, butyric acid and ethyl/propyl in the rumen of lambs (P<0.05). TVFA, acetic acid and propionic acid were significantly higher (P<0.05) than those of the control group in the test Ⅱ group on day 14, and did not differ from those of the test Ⅰ and Ⅲ groups (P>0.05); with the extension of the weaning time, TVFA, acetic acid, propionic acid, and butyric acid as a whole showed a tendency of decreasing firstly and then increasing later; the treatment × time had no effect on TVFA, acetic acid, propionic acid, butyric acid, and ethanol/propanol (P>0.05). In conclusion, the results of this study indicated that the addition of fructooligosaccharides to the starter diet could improve the rumen environment by improving the rumen fermentation function in suckling lambs. The optimum addition of fructooligosaccharides was 1% under the conditions of this experiment.
