Double 3 × 3 was used in rumen of 6 hollow Holstein cows.

Latin square 15 days, during which the influence of different protein was studied.

Rumen fermentation and supplementary feed for local grazing cows

The director's depraved characteristics. Sunflower powder and feather powder

Separate. Three different treatments include concentration: low

Director -SM (long -SM), high director -SM (high -SM) and high director -FM (high -FM).

All cattle were grazed with 23 10 Deutsche Mark winter oatmeal (Oat Lake).

Kg/ha bed, directed by 14.2%, 33.6%, NDF and in vitro digestibility of diabetes mellitus were 82.2%.

Eight weeks. Stingo Sm and H-FM enrichment 15.3%,

23.3% and 24.6% respectively. I compared l and h with the clock team.

Frequency modulation. General walking and gun instructors, it is estimated that chromium is marked with feces, similar.

Interprocess (P "0.05). Total volatile fatty acid concentration regardless of pH value

Rumen fluid was affected, which was therapeutic (P 0.05). L-SM and

Frequency modulation test showed that the concentration of NH3-N in rumen was higher than that of H- Sm (P < 0. 05).

For Oskov and McDonald's (1979). Protein didn't supplement the quantity.

Without changing the consistency of concentrated rumen digestion (P "0.05),

However, the rumen degradation rate is low, which reduces a small part of degradable sources.
