| 1 | Effect of exogenous fibrolytic enzymes on performance and blood profile in early and mid-lactation Holstein cows显示文摘The supplementation of exogenous fibrolytic enzymes(EFE) to dairy cows diets could be a strategy to improve fiber degradation in the rumen which is especially important for the early lactating cows characterized by a high milk energy output and an insufficient energy intake. The objective of this study was to examine the effects of a fibrolytic enzyme product(Roxazyme G2 Liquid, 3.8 and 3.9 mL/kg total mixed ration [TMR] DM) supplemented to a TMR on production performance and blood parameters of dairy cows during early(trial 1) and mid-lactation(trail 2). In addition, rumination activity was measured in trial 2. The nutrient digestibility of the experimental TMR was obtained by using wethers. In the digestibility trial, EFE was supplemented at a rate of 4.4 m L/kg Roxazyme G2 Liquid TMR-DM. The TMR contained 60% forage and 40% concentrate(DM basis). Twenty eight 50 ± 16 days in milk(DIM)and twenty six 136 ± 26 DIM Holstein cows were used in two 8-wk completely randomized trails,stratified by parity and milk yield level. One milliliter of the enzyme product contained primarily cellulase and xylanase activities(8,000 units endo-1,4-? glucanase, 18,000 units endo-1,3(4)-? glucanase and 26,000 units 1,4-? xylanase). No differences in digestibility of DM, OM, CP, NDF and ADF were observed(P >0.05) between the control and the EFE supplemented TMR. Addition of EFE to the TMR fed to early(trial 1) and mid-lactation cows(trial 2) did not affect daily dry matter intake(DMI), milk yield,4% fat-corrected milk, energy-corrected milk(ECM), concentration of milk fat, protein, fat-protein-quotients, somatic cell score, energy balance, and gross feed efficiency of early and mid-lactation cows(P >0.05). Mid-lactation cows(trial 2) fed with TMR enzyme showed a tendency of a slightly higher ECM yield(P = 0.09). The tested blood parameters were not affected by treatment in trials 1 and 2(P >0.05).Exogenous fibrolytic enzymes supplementation did not alter daily time spent ruminating in trial 2(P =0.44). In conclusion, under the conditions of this study, no positive effects of enzyme supplementation on dairy performance and health status of dairy cows during early and mid-lactation were observed. | Anja Peters Ulrich Meyer Sven Danicke | 2015 | Animal Nutrition2015，，3： | 5 |
