“…In this study, the growth heights affected the chemical composition, chlorophyll, phytol, and biomass yield of P. sinese , and this result has been verified in several studies ( King et al., 2013 ; Lv et al., 2017 ; Zi et al., 2017 ). The concentration of pigment decreased gradually with the increase of the growth height of P. sinese .…”

“…Due to multiple cutting, P. sinese is hard to judge its nutritional value through its growth period. To some extent, the growth heights reflect the growth and development stages of plants, which influenced chemical composition and feed quality ( Dong et al., 2013 ; Zi et al., 2017 ). Therefore, we speculate that P. sinese contains more photosynthetic pigments, and the impact of growth heights on the phytol or chlorophyll level also should be clarified.…”

The dynamics and correlations of chlorophyll and phytol content with silage bacterial of different growth heights Pennisetum sinese were investigated. The results demonstrated that the chlorophyll and phytol content of P. sinese before and after ensiled decreased with the increase of growth height. Ensiling significantly reduced pigment content but had no significant effect on phytol. In addition, P. sinese pigment yield before and after ensiled increased with growth heights increasing, and the yield at 150 or 180 cm was obviously higher. Moreover, the higher silage quality V-Score were at 150 or 180 cm growth heights. Furthermore, the silage microbial diversity were varied by growth heights, and some specific undesirable microorganisms (Acinetobacter, Cellvibrio, Sphingobacterium, etc.) were negatively correlated with pigment and phytol content. Therefore, with comprehensive consideration of pigment, phytol yield, and silage quality, the optimum harvest growth height of P. sinese was 150 cm. Furthermore, precise reduction of particular undesirable microorganisms maybe helps to preserve pigments and phytol.

Rheum tanguticum (Rh. tanguticum) is a Chinese medicinal plant traditionally used in the treatment of constipation. As a byproduct, the seeds of this plant are rich in nutrients and phytochemicals. This study aimed to determine and assess seed germination ability, seed physical characteristics, soluble protein content, chemical constituents and antioxidant capacity from different breeding lines, to promote the development and utilization of seed resources. Significant differences were observed for the soluble protein content and antioxidant assays among the ten lines. The contents of aloe-emodin, rhein and catechins accumulated in seeds were extremely low and significantly different from those in roots. In contrast, emodin and chrysophanol were abundant in seeds, and significant differences were observed between seeds and roots. It was found that associations between gallic acid and catechins were not significant for either soluble protein or antioxidant capacity. There was a significantly positive correlation between the contents of four anthraquinones (aloe-emodin, rhein, emodin and chrysophanol) and soluble protein. Seeds have potent antioxidative capacity and relatively high levels of soluble protein content. The rich chemical composition of seeds can be widely used in the medical industry for further development.

“…Differences in forage fragility for BMR and BMRFL versus CONV may help account for decreased chewing time per kilogram of NDF, which subsequently allowed for 0.5 kg/d greater NDF intake for cows consuming bm3 CS hybrids. Fiber with lower lignin or uNDFom content requires less fracture force for exposure of cell wall to microbial degradation (Zi et al, 2017). Eating time on a NDF basis was greater for cows consuming CONV (33.9 min/kg of NDF) compared with cows consuming BMRFL (30.9 min/kg NDF; P = 0.03) and intermediate for cows consuming BMR (32.3 min/kg of NDF).…”

Dry matter intake, lactation performance, and chewing behavior of multiparous Holstein cows (n = 15) fed diets containing a novel bm3 corn silage hybrid with floury kernel genetics were compared with cows fed diets containing commercially available conventional and bm3 hybrids using a replicated 3 × 3 Latin square design with 28-d periods. Cows were housed in tiestalls, milked 3 times/d, and fed a total mixed ration containing 49.0% (dry matter basis) of (1) a conventional corn silage hybrid (CONV); (2) a brown midrib bm3 hybrid (BMR); or (3) a bm3 hybrid with floury kernel genetics (BMRFL). All diets contained 6.3% hay crop silage and 44.7% concentrate. Dietary nutrient composition averaged 32.7% neutral detergent fiber (NDF) and 26.3 starch (% of dry matter). Data were analyzed by ANO-VA using the MIXED procedure in SAS (SAS Institute Inc., Cary, NC). The dry matter intake was greater for cows fed BMR (28.0 kg/d) compared with CONV (26.8 kg/d), whereas dry matter intake for cows fed BMRFL was intermediate (27.6 kg/d). Energy-corrected milk (ECM) yield was greater for cows fed BMR (50.3 kg/d) and BMRFL (51.8 kg/d) compared with CONV (47.2 kg/d). Milk fat yield was higher for cows fed BMRFL (1.87 kg/d) compared with CONV (1.74 kg/d) and BMR (1.80 kg/d). Milk protein yield was greater for cows fed BMR (1.49 kg/d) and BMRFL (1.54 kg/d) compared with CONV (1.36 kg/d). Milk urea-N was reduced for cows fed BMR (11.61 mg/dL) and BMRFL (11.16 mg/dL) compared with CONV (13.60 mg/dL). Feed efficiency (ECM/dry matter intake) was higher for cows fed BMRFL (1.87) compared with CONV (1.76) and BMR (1.79). Milk N efficiency was greatest for cows fed BMRFL (40.4%) followed by BMR (38.1%) and finally CONV (35.3%). Cows fed CONV chewed 5 min more per kilograms of NDF consumed than cows fed either of the BMR hybrids. No differences were observed among diets in apparent total-tract digestibility of NDF (58.1%) or starch (99.3%). Overall lactational performance was enhanced for cows fed diets containing both BMR and BMRFL hybrids versus CONV. In addition, feeding the BMRFL corn silage improved efficiency of component-corrected milk production and milk N efficiency compared with the CONV and BMR silages.
