- Abstract
Napiergrass ( Pennisetum purpureum Schumach.) is one of important feeding ingredients for dairy cows in Taiwan. The lignified napiergrass is not easy to be digested and utilized by cattle, but it is the best medium for cultivating Pleurotus eryngii instead of sawdust. Functional components such as polysaccharides produced by the degradation of napiergrass by fungal mycelium of Pleurotus eryngii can be used as feed additives. The intestinal microorganisms of calf feces were examined by next generation sequencing. The initial bodyweight of treatment was 58.6 ± 4.2 kg and control was 57.1 ± 10 kg. The results of experiment showed that the relative abundance of the specific of microorganisms after 3 months of feeding was higher than that of 2 months of feeding. The experimental group fed for 3 months significantly increased the firmicutes/ bacteroidetes (F/B) ratio and inhibited the species of Tyzzerella nexilis that caused calf bloating and diarrhea. In addition, the weight of the treatment 96.5 ± 10.8 kg was better than the control 90 ± 10.3 kg. From those results, the special feed additives could increase the abundance of intestinal microorganisms and produces economic benefits of promoting calf weight gain during the starter stage.
