The results showed that the degradation rate of neutral detergent fiber(NDF) and acidic detergent fiber(ADF) were significantly increased in rumen when adding malate in ration((P<)(0.05));
The influence of dietary NDF levels on the growing male calves' apparent digestibility ratio of ND and acidic detergent fiber(ADF) was great(P<0.05),the apparent digestibility ratio of NDF and ADF increased with the increasing dietary NDF levels;
The degradability of dry matter(DM),neutral detergent fiber(NDF),acid detergent fiber(ADF) at 48 h and 72 h were 80.67 %,72.47 %,61.44 % and 85.51 %,78.96 %,74.52 % respectively.
The resultsshowed that the efficiency of synthesis of microbial protein(MCP)in stomach was 9.80±0.59g/100g OMD and thedigestibility of acid detergent fibre(ADF)and organic matter(OM)in stomach were 38.79%±1.35% and 49.26%±1.72% respectively.
Digestibility of meat rabbits to main nutrient content of wedelia chinensis had been determined, digestibility of CP、 EE, Ash, Ca, P, hemicellulose, NDF and ADF was 68.72%, 54.27%, 2.65%, 72.30%, 89.80%, 77.39%, 52.95% and 9.38% respectively.
And the digestibility of dry matter, organic matter, nitrogen and ADF of pellet were respectively higher 3.85%(p>0.05), 0.65%(p>0.05), 0.05%(P>0.05), 12.90% ( P>0.05 ) .
The results showed that when WSPO was treated with Le and Di realignment, NDF, HC and ADL decreased by 11.83%-12.84% (P<0.05), 33.41%-36.46% (P<0.05) and 21.98%-25.67% (P<0.05) respectively, compared with the control group;
In our experiment four 42 to 68kg Duroc×Taihu crossbred barrows were fitted with fistulas in the stomach and the caecum. For each barrow a spun nylon bag filled with a sample of ground rice straw was put in the cavity of the stomach or the caecum for 24 hr. and the changes in the contents of ADF, cellulose and lignin were measured with the improved Van Soest analytic method.The average rates of the disappearance (%) of ADF and cellulose in th gastric sample during the period of basal ration were—1.59 and 0....
Rice straw was ammoniated by evaporation of 30% NH4OH solution under plastic coverage for 1-1. 5 month. The crude protein content of the straws increased from 5.4% to 8.46% after ammoniation. The in vitro DMD, OMD for the treated and untreated straw were 49.51%, 50.03% and 41.73%,41.09% respectively.
Three water buffalo cows (two with rumen and abomasum cannula and one with rumen cannula only) under barn feeding condition in winter were used in a series of experiment. Treatment of diet in three periods were as follows: (Ⅰ)rice straw only, (Ⅱ) Ⅰ +NPN, (Ⅲ) Ⅰ +Ⅱ+corn flour. Amount of OM intake was 3% and 21% higher for diet Ⅱ and Ⅲ than the value obtained from diet Ⅰ.Diets Ⅱ and Ⅲ increased the ruminal TVFA, NH_3-N, concentration. The amount and efficiency of MP synthesis were increased from 174.24g, 4.14 ...
