4 IU/kg DM, 1 mg all-rac-[alpha]-tocopheryl acetate = 1 International Unit), were supplemented to the basal ration (VE content 38 IU/kg DM) in a 4 x 4 Latin square design as experimental treatments I, II, III, and IV, respectively.
In the present trial, the VE supply from the basal ration for the cattle was 142 IU/head/d (38 IU/kg DM x 3.
The reason could be that the VE content of the basal ration met the VE requirement of the cows or the supplementation level of 145 mg VE/head/d was not high enough to influence the nutrient digestibility and the performance of the cows.
2013), however, reported that injecting 5 mg sodium selenite and 450 mg VE injections (Viteselen 15, Adwia Company, Tanta, Egypt) two times per week for 1 month increased the serum concentration of GSH-PX of Ossimi rams (VE content in basal ration 15 mg/kg on fed basis).
The 1st group expressed as (control) and received basal ration
while rabbits in 2nd, 3rd, 4* and 5th groups were received the basal ration
supplemented with mixture juice of (LOG) at levels (5, 10, 15 and 20 ml/ kg DM intake) (V/W), respectively.
The experimental groups were designed as (1-) no supplementation to basal ration
(Control-Group I); (2-) supplementation of 500 ppm vitamin C and 200 ppm lead (as lead acetate) to basal ration
(Group II); (3-) supplementation of 1 g/kg propolis and 200 ppm lead (as lead acetate) to basal ration
(Group III); and (4-) supplementing of 200 ppm lead (as lead acetate) to basal ration
(Group IV) for a period of 3-42 days.
