Abstract
The present study was conducted, at the Department of Animal nutrition. Animal Production Research Institute (APRI) and Rumen Department of Animal Production lab, Faculty of Agriculture, Ain Shams University, Cairo, Egypt.
Four agricultural by products used usually as roughages in ruminant diets were incubated with five different ZAD concentrations for four different times. Roughages used were rice straw (RS), Wheat straw (WS), corn stover (CS) and sugarcane bagasse (SCB).
ZAD concentrations were (0, 0.5, 1, 1.5 and 2 ml/kg) in a solution of water, Urea and molasses. Ensiling incubation periods were (1, 2, 3 and 4 weeks). Effect of ZAD on chemical composition, in vitro experimental during different periods (12, 24, 48 and 72 h.) for concentrations (0, 1 and 2 ml/kg) of ZAD and bacterial count was recorded for the tasted roughages. Results indicated that:
1. Treatments increased CP, EE, and decreased CF of all roughages used in the present study.
2. Effect of treatments was significant and clear after 3 and 4 weeks of ensiling.
3. ZAD concentrations had similar effects above 0 ml/ kg DM.
4. SCB was the most affected roughage by treatments.
5. In vitro study showed that SCB was the highest in total gas production (TGP).
6. The highest DMD was observed for CS with ZAD concentration of 2 ml/ kg and after 48 hrs. of incubation.
7. The highest bacterial count was observed with WS treated with 2 ml/kg of ZAD and incubated for 4 weeks.
