The ru- men degradation characteristics of dry matter （DM） and crude protein （CP） of roughage at 6, 12, 24, 48 and 72 h were measured by nylon bag method. The re- suits showed that the effective degradation rates of DM and CP of alfalfa hay were the highest, while higher contents of rapid degradation part and potential degrada- tion part of DM and CP also resulted in higher degradation rates of DM and CP. The effective degradation rates of CP and DM of roughage presented strong positive correlation with CP, but showed strong negative correlation with neutral detergent fiber （NDF）. The effective degradation rates of CP of five roughages successively were alfalfa hay 〉 alfalfa block 〉 ryegrass 〉 silage corn 〉 straw.展开更多

This experiment was conducted with the purpose to test the effect of dietary crude protein level (CP %) of feeds prepared from similar feed ingredients in different ratios on growth performance and survival rate of Rohu fry (Labeorohita). An initial density of 100 fry/m2 was maintained in hapa fixed in the cemented tank. The dietary CP% level of feed tested were 20% CP, 25% CP, 30% CP, and 35% CP fed at 5% body weight. The experiment ran for 53 nursing days. The results showed that there was no significant difference (P > 0.05) in the growth rate (g/day) of fry among treatments. Rather group fed with higher protein level grew comparatively better indicating possibility of increasing need of protein in diets. However, the survival rate (%) of rohu fry was significantly different (P < 0.05) in each tested CP% level of feed. Highest survival (82%) of fry was found in the feed of CP 35% and lowest (56%) in the feed of CP 25%. It was predicted that feed with increasing level of CP % in diet is essential for increasing survival rate.展开更多

Forty-eight adult male Albino Wistar rats weighing 150 - 180 g were randomly divided 8 per group into: group I (control) oral gavaged 3 ml/kg of normal saline;group II received 3 ml/kg of NBLCO;groups III, IV and V received in addition to 3 ml/kg of NBLCO 1 ml/kg vitamin C, vitamin E and 3 ml/kg of honey bee respectively;group VI received 3 ml/kg of honey. After 28 days of treatment, all animals were anaesthetized with chloroform and blood collected by cardiac puncture for analysis. Results showed that NBLCO administration significantly increased erythrocyte sedimentation rate and C-reactive protein while supplementation with antioxidant significantly reversed such effects (p < 0.05). NBLCO significantly reduced platelets and fibrinogen levels compared with the control group (p < 0.05). Interestingly, the vitamin supplementation significantly reduced platelets and fibrinogen levels compared to group II (NBLCO) (p < 0.05). Honey supplementation on the other hand significantly reduced platelets and fibrinogen compared to group II (NBLCO) (p < 0.05). From the results obtained it is concluded that ingestion of NBLCO has the potential to induce development and progression of inflammation but could substantially be mitigated by supplementation with antioxidant vitamins C, E and honey.展开更多
