Abstract This study was aimed to estimate the effect of cultivation stage and supplementation level of sprouted barley (SB) on nutrient content and fermentation quality of fermented total mixed ration (TMR). The SB were collected at day 6 (SB6) and day 8 (SB8) of cultivation stages and substituted at 5% (TMR5) and 10% (TMR10) of TMR on dry matter (DM) basis. These TMR were ensiled into 10 L mini silo (3 kg) for 14 days in triplicate. After silo open, sample (1 kg) was collected for laboratory analysis. Before ensiling, crude protein (CP) was lower (P = 0.012) in SB6 than in SB8. Additionally, DM in TMR10 was slightly lower (P = 0.015) than in TMR5 while CP and acid detergent fiber were higher (P < 0.05). After fermentation, crude ash (P = 0.002), in vitro DM digestibility (IVDMD) (P = 0.001; 73.5 vs. 72.0%) and in vitro neutral detergent fiber (IVNDFD) (P = 0.001; 50.6 vs. 47.7%) were higher in SB6 than in SB8. Additionally, DM (P = 0.002; 64.0 vs. 64.5) in TMR10 was lower than in TMR5, while CP (P = 0.005; 19.7 vs. 18.9%), IVDMD (P = 0.001; 74.5 vs. 71.0%), and IVNDFD (P = 0.001; 52.0 vs. 46.3%) were higher. Fermentation indices and microbial counts were not affected by cultivation stage of SB, except on propionate that higher (P = 0.014) in SB8 than SB6. Silage pH (P = 0.001) was lower in TMR10 than in TMR5, which followed by higher lactate (P = 0.003; 3.27 vs. 2.85%), acetate (P = 0.004; 0.52 vs. 0.42%), propionate (P < 0.001), and LAB count (P = 0.020; 7.49 vs. 7.19%). The interaction effects between cultivation stage and supplementation level only found on propionate production (P = 0.001). Yeast and mold were not affected by cultivation stage and supplementation level of SB. This study concluded SB6 was recommended to improve fermentation quality of fermented diet, and its application on TMR10 could increase not only rumen digestibility but also fermentation indices.

The objective of this study was to evaluate the effects of dietary energy levels on growth performance, rumen fermentation and bacterial community, and meat quality of Holstein-Friesians bulls slaughtered at different ages. Thirty-six Holstein-Friesians bulls (17 months of age) were divided into a 3 × 3 factorial experiment with three energy levels (LE, ME and HE; metabolizable energy is 10.12, 10.90 and 11.68 MJ/kg, respectively) of diets, and three slaughter ages (20, 23 and 26 months). Results indicated that bulls fed with ME and HE diets had higher dry matter intake, average daily gain, and dressing percentage at 23 or 26 months of age. The ME and HE diets also reduced bacterial diversity, altered relative abundances of bacteria and produced lower concentrations of acetate, but higher butyrate and valerate concentrations in rumen fluid. Increasing in dietary energy and slaughter age increased the intramuscular fat (IMF) and water holding capacity. In summary, Holstein-Friesians bulls fed with ME and HE diets, slaughtered at 23 and 26 months of age could be a good choice to produce beef with high IMF. Slaughter age may have less influence than dietary energy in altering fermentation by increasing amylolytic bacteria and decreasing cellulolytic bacteria, and thus, further affecting meat quality.
