Effects of dietary non-fibrous carbohydrate (NFC) to neutral detergent fiber (NDF) ratio change on rumen bacterial community and ruminal fermentation parameters in Chinese black Tibetan sheep (Ovis aries)
This study evaluated the effects of different non-fibrous carbohydrate/neutral detergent fiber (NFC/NDF) ratios on the rumen fermentation parameters and bacterial community of black Tibetan sheep. Fifteen 2-month-old rams with an average body weight of 10.45 ± 0.96 kg were randomly assigned to three...

Zusammenfassung: | This study evaluated the effects of different non-fibrous carbohydrate/neutral detergent fiber (NFC/NDF) ratios on the rumen fermentation parameters and bacterial community of black Tibetan sheep. Fifteen 2-month-old rams with an average body weight of 10.45 ± 0.96 kg were randomly assigned to three treatments and fed NFC/NDF of 1.82 (H group), 1.16 (M group), and 0.71 (L group), respectively. This study was conducted for 127 d, including 7 d of adaption to the diets. The fermentation parameters and bacterial characteristics of rumen fluid were measured after the end of feeding trials. According to the results, the concentrations of propionate and total volatile fatty acids (TVFA) increased in the H group than those in the L group (P |
